Background

The processing of minerals usually needs to process larger materials into smaller particles for effective utilization, and waste sand after casting application is subjected to casting high temperature to form blocks with higher strength. Efficient crushers are required to break apart the lumps, separating out sand particles, which can also be used in the casting process, or to make sodium silicate.

Disclosure of Invention

Based on the problems, the invention provides a variable-section negative-pressure drop-hammer type crusher, which is used for solving the problems of low efficiency of crushing materials, low product qualification rate and environmental pollution in the prior art. According to the invention, negative pressure is formed in the cavity through the air draft device, after a large material is beaten by the drop hammer, separated small sand grains timely pass through the air holes to enter the cavity and are taken away by wind, so that the times of hitting the material in the barrel body are increased, the crushing efficiency is improved, the product yield is improved, and meanwhile, dust is timely taken away by the wind, so that the pollution to the environment is reduced.

The invention specifically adopts the following technical scheme for realizing the purpose:

the utility model provides a variable cross section negative pressure gets rid of hammer crusher, includes the barrel, the top surface of barrel is equipped with the feed inlet, and the bottom surface is equipped with the discharge gate, the pivot that extends to in the barrel is installed to the top surface of barrel, power device is installed to the upper end of pivot, be connected with the tup through the hinge along its direction of height in the pivot, install the connecting piece on the inner wall of barrel, install the inner tube on the connecting piece, leave the cavity between inner tube and barrel, it has a plurality of gas pockets to open on the inner tube, open the lower part of barrel has with the communicating air outlet of cavity, install updraft ventilator on the air outlet.

The working principle is as follows: the power device drives the rotating shaft to rotate, the installation block capable of installing the hinge shaft can be installed on the rotating shaft, or the installation block capable of installing the hinge shaft and the rotating shaft are integrally formed, the rotating shaft drives the hammer head to rotate, the power device capable of driving the rotating shaft to rotate is a conventional power device, such as a motor and the like, when a material falls down from the feed inlet into the barrel body, the material is hit by the high-speed rotating hammer head to be broken, the hit material is collided with the lining plate component to be broken, the back impact is collided with the hammer head again, and the hard impurities are discharged from the discharge port below. The external updraft ventilator of air outlet, updraft ventilator here can be the fan, also can be at waste sand processing system, have originally and establish for the environmental protection wind-force system, also can be from the wind-force system who takes among the entire system, updraft ventilator makes the cavity in form the negative pressure, under the effect of negative pressure, forms wind from inside to outside, and wind gets into the barrel from feed inlet and discharge gate, takes away the tiny particle, passes the gas pocket on the welt subassembly and gets into the cavity, finally discharges from the air outlet.

By the technical scheme, small sand grains separated by beating are taken away with wind in time, so that the obstruction of the sand grains is reduced, large materials are directly beaten, the probability and the strength of beating the large materials are increased, and the efficiency of crushing the materials is improved; after the large materials are beaten, the separated small sand grains are timely taken away by wind, so that the small sand grains are prevented from being repeatedly beaten and excessively crushed, and the product percent of pass is improved; the dust is sucked away by wind in time and is emptied after dust removal, thereby reducing the environmental pollution.

As a preferable mode, the inner cylinder is composed of a plurality of lining plate components, the lining plate components are installed on the connecting piece through the installation piece, and the plurality of air holes are uniformly formed in the lining plate components.

As a preferred mode, the welt subassembly includes left welt, mounting bar and the right welt as an organic whole of mutual shaping from left to right mutually, left side welt and right welt symmetry each other, the even division of gas pocket is on left welt and right welt, the installed part is installed on the mounting bar.

Preferably, the lining plate component is trapezoidal, and the width of the upper part of the lining plate component is larger than that of the lower part of the lining plate component.

Preferably, the lower portion of the liner plate assembly is further provided with a straight section.

Preferably, the mounting member is a bolt, and the connecting member is a bracket.

Preferably, the number of the air outlets is multiple, and the air outlets are uniformly formed in the lower portion of the cylinder.

In a preferred form, the inner cylinder is tapered and the cross-sectional area of the upper portion of the inner cylinder is greater than the cross-sectional area of the lower portion.

Preferably, the inner cylinder is made of a wear-resistant plate.

Preferably, the upper part of the rotating shaft is mounted on the top surface of the cylinder through an upper bearing seat, and the lower end of the rotating shaft is mounted on the bottom surface of the cylinder through a lower bearing seat.

The invention has the following beneficial effects:

(1) after the materials enter the inner barrel, the materials are quickly crushed through repeated striking collision of the hammer head and the lining plate component, the struck and separated sand grains slide away along with wind in time, so that the obstruction of the sand grains is reduced, large materials are directly struck, the striking probability and strength of the large materials are increased, and the crushing efficiency is improved.

(2) After the large materials are beaten, the separated sand grains are timely taken away by wind, so that the sand grains are prevented from being repeatedly beaten and excessively crushed, and the grain size qualified rate is ensured.

(3) The sand grains are taken away by wind in time, so that energy consumption loss caused by repeated striking is avoided, the load is reduced, the power is reduced, a wind power system which is set for protecting the environment originally exists in the waste sand treatment system, the wind power system is directly applied to an air draft device, and a special air draft device is not required to be arranged, so that the energy consumption is reduced.

(4) The dust in the invention is sucked away by wind in time, and is emptied after dust removal, thereby avoiding environmental pollution and harm to the body of workers.

(5) The sand grains are taken away by wind in time, so that repeated beating by the hammer head and the lining plate is avoided, and the service lives of the hammer head and the lining plate are prolonged.

(6) The variable cross-section structure of the invention, especially the variable cross-section structure with large opening and small bottom, and the suction effect of negative pressure, improve the efficiency, and compared with the prior hammer crusher, the variable cross-section structure of the invention can be manufactured smaller and lighter under the same yield, thereby reducing the manufacturing cost.

(7) The lining plate component comprises a left lining plate, a mounting strip and a right lining plate which are mutually formed into a whole from left to right, the left lining plate and the right lining plate are mutually symmetrical, and the two lining plates are equivalently combined into a whole, so that the left lining plate and the right lining plate are more conveniently mounted on the connecting piece.
