Description

Technical Field

[0001] The invention belongs to the technical field of brick blank raw material crushing equipment, and specifically refers to a brick blank raw material crushing machine. Background Art

[0002] Brick blanks are semi-finished products for making bricks. In the production process, raw materials such as clay, shale, coal gangue, etc. need to be crushed first, then mixed and kneaded, pressed and formed, and finally dried or dried to form brick blanks. After proper treatment and firing, these raw materials can be made into various types of bricks for use in construction and civil engineering.

[0003] Clay, shale, coal gangue and other materials contain a variety of impurities, which are mixed with brick raw materials after crushing, affecting the hardness of the finished bricks. Therefore, it is necessary to remove the impurities that affect the hardness of the brick raw material powder in the brick raw material powder; static electricity, humidity and other reasons often cause the brick raw material powder to accumulate in the crushing equipment, resulting in unbalanced operation of the crushing equipment and increased kinetic energy required for operation. It is necessary to avoid the accumulation of particulate matter in the crushing equipment; the crushed ore particles have a large splash range due to external environmental reasons. In order to reduce the diffusion range of the ore particles during discharge, that is, when ore particles are about to fall outside the conveyor belt, it is necessary to automatically limit the range of the ore particle falling space to ensure that all crushed ore particles can be effectively transmitted. Summary of the invention

[0004] In view of the above situation, in order to avoid ore particles splashing out of the conveyor belt, reduce the accumulation volume of brick embryo powder in the crushing equipment, and at the same time screen out the lighter impurities in the brick embryo powder, the present invention provides a brick embryo raw material crushing machine, which effectively limits the diffusion range of the brick embryo powder during discharge, so that it can fully fall on the conveyor belt, screen out the lighter impurities in the brick embryo raw material, improve the hardness of the brick embryo, reduce the amount of brick embryo powder accumulated in the gaps and corners of the crushing equipment, and balance the internal weight of the crushing equipment.

[0005] The technical solution adopted by the present invention is as follows: the present invention provides a brick raw material crushing machine, comprising a horizontal hammer crushing device, a roller crushing device and a conveyor belt for sending out powder, wherein the conveyor belt is arranged below the horizontal hammer crushing device, the roller crushing device is placed on the ground, and the discharge end of the roller crushing device is arranged above the feed end of the horizontal hammer crushing device; The roller crushing device includes a roller crusher that automatically adjusts the discharging direction and a small-particle raw material conveyor belt that prevents the conveyor belt from sticking.

The roller crusher first crushes large pieces of ore material into small particles, and the small particles of ore fall onto the small-particle raw material conveyor belt below, and are sent to the feed end of the horizontal hammer crushing device through the small-particle raw material conveyor belt.

[0006] Furthermore, the roller crusher includes a crusher casing, a crushing roller, an ore guide plate, a discharge end baffle, an impact plate, a pressing column, a column slide, and a discharge angle adjustment plate.

[0007] Furthermore, the ore guide plate is arranged as a three-dimensional trapezoidal structure, so as to further reduce the falling range of the crushed ore, the discharging end baffle plate and the impact plate are connected by a torsion spring, the impact plate and the pressing column are connected by a torsion spring, the discharging angle adjustment plate and the bottom wall of the discharging end baffle plate are connected by a torsion spring, the width of the column slide groove is greater than the width of the pressing column, and when the impact plate flips over, the pressing column is limited by the column slide groove, and can perform contact tail pressing on the discharging angle adjustment plate, so that the front end of the discharging angle adjustment plate is tilted toward the middle position of the crusher casing, thereby further reducing the discharging range of the ore particles.

[0008] Furthermore, the crushing roller is connected to a gear, and two groups of crushing rollers are provided. The gears connected to the two groups of crushing rollers rotate in opposite directions, which can squeeze the ore. The crushing roller is driven by a motor, and the top wall of the ore guide plate is set as an arc-shaped surface. The ore guide plate with a curved surface structure can move the ore to the center position of the two groups of crushing rollers.

[0009] Furthermore, the small particle raw material conveyor belt includes a conveyor belt baffle structure, a particle ore conveyor belt, a bottom collecting box, a paddle, and a collecting trough. The conveyor belt baffle structure is fixedly installed on the ground through a bracket, the particle ore conveyor belt is engaged and rotatably set on the conveyor belt baffle structure, and the particle ore conveyor belt is engaged and installed on the roller on the conveyor belt baffle structure. The bottom collecting box is fixedly installed below the particle ore conveyor belt through a bracket, the collecting trough is fixedly set on the bottom collecting box, and the paddle is fixedly installed on the upper wall of the bottom collecting box.

[0010] Furthermore, the middle position of the granular ore conveyor belt is recessed downward, which is beneficial to the transportation of granular ore on the conveyor belt. The granular ore conveyor belt includes an ascending part and a horizontal part. The connection between the ascending part and the horizontal part is limited by pressing the edge of the connection between the two by a roller. The paddles and the collecting troughs are installed on the bottom collecting box in an alternating manner, and the paddles are in contact with the granular ore conveyor belt. The attachments on the granular ore conveyor belt are swept by the paddles and fall into the collecting trough below.

[0011] Preferably, the paddle is made of rubber material, has an arc-shaped curved surface structure, and has a side wall with rounded corners.

[0012] Furthermore, a group of fans is provided on the conveyor belt baffle structure, and the fans are arranged below the rising part of the particle ore conveyor belt, and the fans supply air to the feeding end of the horizontal hammer crushing device.

[0013] Furthermore, the horizontal hammer crushing device includes a ball mill crushing structure, a ball mill feeding device and an anti-adsorption cleaning device, wherein the ball mill crushing structure is fixedly arranged above the conveyor belt through a baffle, the ball mill feeding device is connected to the ball mill crushing structure, and the anti-adsorption cleaning device is mounted in the ball mill crushing structure; The ball mill crushing structure includes a pinion, a gear ring, a single-sided limit plate, a single-sided limit ring and a ball mill shell. The single-sided limit ring is fixedly installed on the bracket. One end of the ball mill shell is engaged and rotatably set on the single-sided limit ring. The single-sided limit plate is engaged and rotatably connected to the other side of the ball mill shell. The pinion is fixedly installed in the single-sided limit plate. The gear ring is fixedly installed on the outer wall of the ball mill shell. The pinion is meshed with the gear ring. The pinion drives the gear ring to rotate, which drives the ball mill shell to rotate on the single-sided limit ring.

[0014] Furthermore, the pinion is driven by a motor, and the ball mill shell includes a truncated cone shell, a cylindrical shell and a discharge port baffle. The truncated cone shell is snap-fitted and installed on a single-side limiting ring, and the cylindrical shell is fixedly installed on the circular bottom wall of the truncated cone shell. The truncated cone shell is provided with two groups, and the discharge port baffle is snap-fitted and installed on the side wall of the cylindrical shell. An array of crushing balls is provided in the ball mill shell.

[0015] Furthermore, the ball mill feeding device includes a spiral auger, a feed pipe, a strip filter and an expansion bell mouth. The feed pipe is mounted on the inner wall of a truncated cone-shaped shell in a snap-fitting and rotatable manner, the spiral auger is mounted in the feed pipe in a snap-fitting and rotatable manner, the strip filter is mounted on the bottom wall of the feed pipe, the expansion bell mouth is mounted on the feed pipe, and the expansion bell mouth is mounted in the truncated cone-shaped shell. When the particle ore conveyor belt delivers granular ore debris to the top of the feed pipe, the fan blows out lighter impurities in the ore. After the remaining small-particle ore powder enters the feed pipe, the smaller diameter part is screened by the strip filter and falls outside the feed pipe. The remaining ore particles are delivered into the ball mill shell by the spiral auger, and the spiral auger is driven by a motor.

[0016] Furthermore, the anti-adsorption cleaning device includes a convex rib plate, an anti-adsorption barrier plate, a cleaning protrusion, and a hanging rod. The convex rib plate is fixed in an array along the inner wall of the truncated cone-shaped shell. Gaps are provided between the convex rib plates on the same horizontal plane. The cleaning protrusion engages and slides in the gap between the convex rib plates. The hanging rod is suspended above the ball mill shell. The anti-adsorption barrier plate is fixedly mounted on the hanging rod, and the anti-adsorption barrier plate is arranged in the ball mill shell. The cleaning protrusion is fixedly mounted on the side wall of the anti-adsorption barrier plate. During the crushing process, the cleaning protrusion prevents ore powder from accumulating in the gap between the convex rib plates, thereby ensuring the stability of the ball mill shell during rotation.

[0017] Preferably, the anti-adsorption barrier plate is provided with small holes for filtering ore powder, and the convex ridge plate is set to a right-angled triangular prism structure. The convex ridge plate is used to increase the gravitational potential energy of the crushing ball. The higher the position of the ball is lifted, the greater the gravitational potential energy released when it falls, and the better the crushing effect.

[0018] Furthermore, the single-sided limit plate and the single-sided limit ring are both provided with a slot for engaging the suspension rod. When the ball mill shell rotates, the single-sided limit plate and the single-sided limit ring remain in a fixed state, so the suspension rod will not be displaced due to the rotation of the ball mill shell, and the anti-adsorption blocking plate is always in the upper space position inside the ball mill shell.

[0019] The present invention provides a brick raw material crushing machine, which has the following beneficial effects: (1) The gravity released by the ore particles falling on the impact plate is converted into kinetic energy for the pressing column to move downward, so that the pressing column slides downward along the column chute, driving the tail of the discharge angle adjustment plate to press down and the head to tilt up, thereby reducing the range of splashing of ore particles discharged by the discharge end baffle. The discharge angle adjustment plates are arranged on both sides of the granular ore conveyor belt, effectively preventing the possibility of ore particles falling out of the granular ore conveyor belt; (2) The groove in the middle of the granular ore conveyor belt prevents the ore particles from falling during the conveying process. The arc-shaped surface structure of the paddle reduces the amount of brick raw material powder attached to the granular ore conveyor belt, effectively reducing the power required to drive the granular ore conveyor belt; (3) A set of fans is set between the particle ore conveyor belt and the feed pipe, so that the ore particles can obtain horizontal wind energy when they fall from the particle ore conveyor belt to the feed pipe below. The lighter impurities whose falling potential energy is less than the wind energy will be directly blown out of the feed pipe by the wind energy, thus making preparations to prevent impurities from entering the ball mill shell; (4) The combination of the truncated cone shell and the cylindrical shell with a bell-mouth structure causes the ore particles in the ball mill shell to move to the middle position, so that the ore particles in the middle position are continuously hammered, thereby improving the efficiency of ore particle crushing; (5) The convex ribs are used to increase the gravitational potential energy of the crushing ball. The higher the ball is lifted, the greater the gravitational potential energy released when it falls, and the better the crushing effect. Multiple sets of shorter ribs are used to replace one set of long ribs, which reduces the volume of powder that can be accumulated at the connection between the ribs and the ball mill shell. At the same time, in conjunction with the cleaning protrusions on the anti-adsorption barrier plate and the rotation of the ball mill shell itself, the cleaning protrusions can continuously clean the brick powder in the gaps between the ribs.

[0035] The small particle raw material conveyor belt 4 includes a conveyor belt baffle structure 13, a particle ore conveyor belt 14, a bottom collecting box 15, a paddle 16, and a collecting trough 17.

The remaining large pieces of ore contact the crushing rollers 6 and the ore guide plate 7 respectively. The arc-shaped upper wall on the ore guide plate 7 transports the ore to the crushing rollers 6 in the middle position. The two groups of crushing rollers 6 rotate toward the middle position to crush the ore on the crushing rollers 6 into small particles. The remaining impurities attached to the ore also pass through the crushing rollers 6 and fall onto the discharge end baffle 8 below. In order to allow the ore particles to fall completely onto the particle ore conveyor belt 14, a rotating impact piece is provided on the side wall of the discharge end baffle 8. 9.

During this process, the fan 20 continues to run, and the fan 20 removes the lighter impurities, Powder impurities are separated before the ore particles enter the feed pipe 33; when the ore conveyor belt 14 moves to the top of the bottom collecting box 15, if there are impurity materials such as small particles stuck, adsorbed, and adhered to the ore conveyor belt 14, the paddle 16 is close to the groove on the ore conveyor belt 14 to sweep off the attachments on the ore conveyor belt 14, and the particles fall into the collecting tank 17 below, ensuring that there are fewer impurities on the ore conveyor belt 14 and will not affect the quality of the brick embryo; after the ore particles enter the feed pipe 33, the spiral auger 32 rotates to transport the ore particles into the ball mill housing 28. During the transportation of the ore particles, some small particles are too small in size and are screened by the strip filter 34 when passing through it, and fall downward, and the remaining The remaining ore particles pass through the expansion bell mouth 35 and enter the ball mill housing 28; the pinion 24 rotates, and the gear ring 25 rotates synchronously to rotate the ball mill housing 28, and the metal balls and ore particles in the ball mill housing 28 obtain rotational kinetic energy and gravitational potential energy. When the metal balls move to a high position in the ball mill housing 28, they fall downward to release gravitational potential energy, and smash the ore particles below into powder. After continuous circulation, the ore particles are continuously crushed into fine particles; in this process, since the ball mill housing 28 is composed of two groups of frustum-shaped housings 29 and one group of cylindrical housings 30, the ore particles on both sides of the ball mill housing 28 move to the middle position of the ball mill housing 28, so that the ore particles are more concentrated and the crushing effect is better;When the convex rib plate 36 lifts the metal balls upward, small particles will accumulate at the connection between the convex rib plate 36 and the ball mill housing 28. In order to reduce the stock of small particles, the original long rib structure is changed into a plurality of short rib plates 36. In order to reduce the ore powder accumulated in the gaps between the rib plates 36, the anti-adsorption blocking plate 37 is suspended and installed by the suspension rod 39. When the cleaning protrusion 38 rotates in the ball mill housing 28, the ore particles and powder in the gaps between the rib plates 36 are scraped and dropped. When the crushed ore powder is taken out, the discharge port baffle 31 is rotated downward, and the discharge port baffle 31 is removed, so that the ore powder in the ball mill housing 28 falls onto the conveyor belt below. After being transported and collected by the conveyor belt, the powder required for raw materials of brick embryos can be obtained. ;
