Detailed Description

The embodiments of the invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout, are exemplary and are intended to be illustrative of the invention, and not to be construed as limiting the invention.

The embodiment of the invention has no auxiliary equipment, such as a spiral feeding machine; a driving part such as a motor and a speed reducer; and electrical control section, but no section without claims should be taken as limiting the invention.

The present invention throwing machine 100 is described below with reference to fig. 1-3.

As shown in fig. 1, the material throwing machine 100 according to the present invention includes a spiral distributor 10, a casing 20, and a material throwing disk 30.

The thrower 100 is fixed on the combustion equipment through a connecting plate 27.

The receiving hopper 11 of the material throwing machine 100 is used for receiving materials conveyed by other equipment, such as a spiral feeding machine and the like, and can also be used for directly storing the materials.

As shown in fig. 1, a shaft sleeve 23 is disposed in the housing 20, and a dust seal 24 and a bearing 25 are disposed inside the shaft sleeve 23.

The material throwing disk 30 is mounted in the bearing 25 and the sealing member 24 through a rotating shaft 33.

The lower end of the rotating shaft 33 is provided with a belt wheel 34, and the belt wheel 34 is connected with a separate power system to obtain rotary power.

The annular partition 22 is used for separating the two throwing disks and respectively rotating the two throwing disks.

In fig. 2, the receiving hopper 11 of the screw dispenser according to the invention is shown connected to the barrel 12, and the dispensing pipe 13 is connected to both the barrel 12 and the casing 20.

As shown in figure 2, two ends of the machine barrel are provided with end covers 14, bearings 16 are arranged on the end covers, two ends of a rotating shaft 18 are respectively arranged in the bearings 16, and a belt wheel 17 is arranged at one end of the rotating shaft 18 and is connected with an independent power system.

The operation of the thrower according to the invention is described below:

when the material throwing machine 100 operates, the material in the receiving hopper 11 on the spiral distributor 10 is filled with the material, the belt wheel 17 rotates under the action of external power, and the material moves towards the two material distributing pipes under the action of two sections of reverse spiral blades on the spiral 15 and falls onto the material throwing disc in the shell through the material distributing pipes.

when the material throwing machine 100 operates, the belt wheel 34 on the material throwing disk 30 starts to rotate under the action of another external power, when a material enters the material throwing disk 30, the material passes through the material distributing cone 35 on the material throwing disk 30 and is forced to move towards the edge of the material throwing disk 30 under the action of centrifugal force, the upper blade 31 of the material throwing disk 30 accelerates the material, and when the material passes through the discharge hole 26, the material is thrown out along the tangential direction of the material throwing disk 30;

The material throwing machine 100 has two material throwing discs which run simultaneously, so that the material throwing surface formed in front of the material outlet 26 is in a regular fan shape; the electric control part can endow the throwing disc with different speed curves according to the shape and the size of the combustion chamber, so that the throwing materials are uniformly distributed in the combustion chamber.

The number of the throwing disks of the throwing machine 100 is 2, but not limited to 2, and may also be 1, and there may be more according to the size of the combustion chamber.

Few parts of the materials fall under the throwing disk in the throwing process, the throwing disk 30 is blocked due to long-term accumulation, and the falling materials are thrown out again by the lower blade 32 of the throwing disk 30.

The thrower 100 is installed on a heating device, the thrower 100 can receive the conduction heat and partial radiation heat of the heating device, the high temperature of the thrower 100 is caused, the safety of the device is affected, and the blowpipe 21 can resist heat and radiate the thrower 100, so that the device is prevented from being damaged.

The blowpipe 21 is connected to the external fan system 3.

The total number of the power systems of the material throwing machine 100 is 3, and the power systems of the material distributor 1, the material throwing disc 2 and the fan system 3 and 3 are controlled in a unified way and do not operate respectively.

The material throwing machine 100 is not limited to the installation and operation mode, and the material throwing machine can be fixed on a spiral feeding machine and can be in butt joint with a combustion device, and the spiral feeding machine and the material throwing machine can be controlled simultaneously.

The thrower 100 can also be provided with a stand and wheels independently, and becomes independent running equipment and can be used in butt joint with combustion equipment.
