Technical Field

The invention relates to the field of solid granular material conveying and dredging, in particular to a safety plug removing device for a material hopper.

Background

Most of the existing hoppers for feeding are in a vertically-arranged funnel shape, the upper ends of the hoppers are provided with feed inlets, the lower ends of the hoppers are provided with discharge outlets, and the hoppers are in a tapered tubular structure with a large upper part and a small lower part, such as a curved shrimp coal hopper, so that the pressure borne by the materials is gradually increased when the materials flow downwards, the cross-sectional area of through flow is smaller, and the friction and extrusion force between the materials and the hopper wall and between the materials are larger and larger; the materials are easy to extrude into an arch, and the downward flow of the materials is blocked; when the material granule is little, the ash is big, humidity is big, the stickness is big, the mobility in material and the hopper is very poor, can often take place blocking phenomenon, and the material in case the jam can seriously influence equipment safety, especially rubbish now.

The name is: in the application of the hopper bin wall to the air hammer (patent number: 201310052306.7), the air hammer at the piston rod end of the air cylinder is used for rapping the outer wall of the hopper to realize the dredging of the feed opening. It has better effect on dry powder or granular materials. However, the existing waste incineration power generation is more and more popularized, wherein the humidity and viscosity of materials to be incinerated are extremely large, the material blocking phenomenon is extremely easy to occur during the blanking, the blanking port cannot be effectively dredged by the rapping of the piston rod, the common method in the prior art is to open the observation port at the blanking port, a worker uses one material smashing drill rod to stretch into the observation port to dredge the material blocking position, and the mode is time-consuming, labor-consuming and has potential safety hazards.

Disclosure of Invention

The invention aims to provide a safety-in-use and good-dredging-effect safety-type safety-rising blockage clearing device.

In order to realize the purpose, the technical scheme is as follows: a safety blockage removing device comprises a cylinder arranged beside a shrimp curve blanking hopper, the cylinder is fixedly connected with a cylinder support, and a telescopic path of a piston rod on the cylinder penetrates through a hopper wall and a blanking opening of the hopper.

The blockage at feed opening department is directly beaten through the piston rod in the above-mentioned scheme, compare in clear stifled through the vibration, it is clear stifled ability stronger, prevents that stifled mediation effect is better, has good effect equally to the blockage that viscidity is big.

Detailed Description

A safety blockage removing device comprises a cylinder 30 arranged beside a shrimp curve blanking hopper 1, wherein the cylinder 30 is fixedly connected with a cylinder support 20, and a telescopic path of a piston rod 32 on the cylinder 30 penetrates through the wall of the hopper 1 and a blanking port. It also can be other power device only as an optimal selection scheme of drive piston rod 32 motion among the above-mentioned scheme, hopper 1 is also only one of hopper under the dried small shrimp curve, it also can be applicable to other hopper down equally, strike artificial ramming material borer operation of material simulation of jam through piston rod 32 disect insertion feed opening, labour saving and time saving and impact dynamics are bigger more to be favorable to dredging the feed opening, the problem of material funnel unloading putty has been solved, reach the purpose of broken arch mediation.

The cylinder support 20 is fixedly arranged on the side wall of the hopper 1 above the feed opening, and the protective pipe 22 sleeved on the outer side of the cylinder body of the cylinder 30 is obliquely arranged on the cylinder support 20. As the bucket diameter of the hopper 1 under the shrimp curve is larger, the length of the piston rod 32 is limited by the specification of a conventional cylinder, and in order to provide the longer piston rod 32 to increase the mass of the piston rod and improve the striking impulse, a section of rod body of the piston rod 32 which retracts to the right position is still positioned outside the cylinder body, so as to carry out enclosure on the piston rod, the protective pipe 22 is arranged, the cylinder can be integrally arranged in the protective pipe, the enclosure is obtained under the non-use state, and the length of the protective pipe 22 is usually designed to be consistent with the length of the cylinder assembly in the retraction state.

The forward extending direction of the piston rod 32 is biased towards the conveying direction of the conveying mechanism below the feed opening. Namely, the included angle between the forward extending direction of the piston rod 32 and the conveying direction of the conveying mechanism below the feed opening is smaller than 90 degrees, so that the blocked materials can be pushed to the downstream of the conveying mechanism below the feed opening, and the situation that the materials return to the position of the feed opening after being pushed to the upstream and are piled up and blocked again with the newly-fallen materials at the feed opening is avoided. The anti-blocking dredging effect is optimal.

The front end of the piston rod 32 is conical or wedge-shaped or cylindrical. The taper or wedge shape facilitates cleaning.

A buffer sleeve 40 is flanged to the end of the protection tube 22 through which the piston rod 32 passes. This facilitates the connection of the cushion sleeve 40 to the sheath 22.

One end of the buffer sleeve 40 is connected with the protective tube 22, via holes 411 are formed in the end plates 41 at the two ends of the buffer sleeve 40, check rings 42 are arranged on the inner side plate surfaces of the two end plates 41, the peripheral size of each check ring 42 is larger than the aperture of each via hole 411, the inner hole size of each check ring 42 is smaller than the aperture of each via hole 411, and two ends of a spring 43 sleeved on the piston rod 32 abut against the check rings 42 respectively. The provision of the damping sleeve 40 ensures that in both extreme positions, i.e. when the piston rod 32 is extended or retracted into the extreme positions, the piston strikes the end cap of the cylinder.

The cleaning brush ring 44 is arranged at the outer end nozzle of the buffer sleeve 40. The cleaning brush ring 44 is used to remove the coke ash adhered to the piston rod 32 in the furnace wall, and prevent the coke ash from accumulating and blocking the tube body 22.

The cleaning brush ring 44 is a ring-shaped brush as shown in fig. 2. The annular brush is beneficial to cleaning fine granular coke ash.

The cleaning brush ring 44 is an annular brush blade with the blade opening facing outward as shown in fig. 3. The brush shovel facilitates cleaning of foreign matter attached to the piston rod 32.

The piston rod 32 outside the two retainer rings 42 is provided with an annular protrusion 321, the protrusion 321 and the piston rod 32 are arranged concentrically, the peripheral size of the piston rod protrusion 321 is smaller than the aperture of the end plate via hole 411, and the peripheral size of the protrusion 321 is larger than the inner hole size of the retainer ring 42. One protrusion 321 is provided near the end of the piston rod 32, and the distance between the two protrusions 321 corresponds to the stroke of the piston. For example, when the piston rod 32 is extended and the piston is about to approach the front end of the cylinder, the protrusion 321 contacts the retainer 42 first, and the speed of the piston rod 32 is reduced under the buffering action of the compression spring 43, so that the impact of the piston on the front end cover of the cylinder is relieved obviously, and vice versa.

The safety blockage removing device is reasonable in structure and safe and reliable to use, solves the problem of material blockage of a material funnel during discharging, and improves production efficiency.
