Description

Technical Field

[0001] This utility model relates to the field of screening device technology, and in particular to a calcium hydroxide impurity screening device. Background Technology

[0002] The calcium hydroxide impurity screening device is a specialized piece of equipment used to separate and purify impurities from calcium hydroxide raw materials or finished products. Its core function is to remove solid impurities from calcium hydroxide through physical or mechanical means, thereby improving product purity and meeting the purity requirements of industries such as construction, chemical, environmental protection, and food.

[0003] When using a calcium hydroxide impurity screening device to screen impurities in calcium hydroxide raw materials or finished products, the calcium hydroxide raw materials need to be fed into the feed hopper. The calcium hydroxide raw materials need to be initially filtered through the filter plate at the bottom of the feed hopper before they can be screened by the vibrating screen. However, if a lot of raw materials accumulate in the feed hopper, they can easily form a whole, which can clog the filter holes of the filter plate at the bottom of the feed hopper, thus reducing the screening efficiency of the material. Utility Model Content

[0004] This invention provides a calcium hydroxide impurity screening device to address the problem that excessive accumulation of raw materials in the feed hopper can easily form a solid mass, clogging the filter holes of the filter plate at the bottom of the feed hopper and thus reducing the material screening efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a calcium hydroxide impurity screening device, comprising a support frame, a vibrating screen mounted on the top of the support frame, a discharge hopper welded to one side of the bottom of the vibrating screen, the discharge hopper being inserted inside the support frame, a feed hopper welded to the other side of the top of the vibrating screen, and an auxiliary device provided on one side of the vibrating screen and the feed hopper. The auxiliary device uses a striking plate and an inclined plate to strike one side of the vibrating screen and the feed hopper, thereby causing the calcium hydroxide raw material or finished product clogging the filter holes to detach from the filter holes.

[0006] The effect achieved by the above components is as follows: by setting the striking plate and the inclined plate, and adjusting the striking plate and the inclined plate, the striking plate and the inclined plate will strike one side of the vibrating screen and the feed hopper respectively. This will cause the filter plate inside the feed hopper to vibrate, which will help to remove the material from the filter holes and prevent the filter holes from being blocked, thus preventing the problem of reduced material screening efficiency.

[0007] Preferably, the auxiliary device includes a striking plate and an inclined plate, the inclined plate being welded to the top of the striking plate. The striking plate and the inclined plate are respectively disposed on one side of the vibrating screen and the feed hopper. Auxiliary plates are symmetrically installed on the top of the striking plate. Both auxiliary plates are fixedly installed at the bottom of the vibrating screen. Springs are fixedly installed on both sides of the striking plate, and one end of each spring is fixedly installed on both sides of the vibrating screen.

[0008] The effect achieved by the above components is as follows: pushing the striking plate will cause the inclined plate to move towards the feed hopper. When the striking plate moves, it will compress the spring, causing the spring to deform until the striking plate and the inclined plate hit one side of the vibrating screen and the feed hopper. When the force applied to the striking plate is removed, the spring will reset and drive the striking plate and the inclined plate to automatically move away from the feed hopper. The above operation is repeated, which can make the filter plate inside the feed hopper vibrate continuously, which is conducive to the material in the filter holes leaving the filter holes.

[0009] Preferably, the spring has a round rod inside, one end of which is fixedly installed on one side of the impact plate, and the round rod is slidably installed on one side of the vibrating screen.

[0010] The effect achieved by the above components is that by setting up the round rod, the round rod can guide the spring, which helps to prevent the spring from easily bending during deformation.

[0011] Preferably, a circular block is fixedly installed at one end of the circular rod, and the outer diameter of the circular block is larger than the outer diameter of the circular rod.

[0012] The effect achieved by the above components is that by setting up a circular block, the circular block can block one end of the circular rod, which helps to prevent the circular rod from detaching from the inner wall of the vibrating screen due to misoperation.

[0013] Preferably, the same rubber plate is fixedly installed on the side of the striking plate and the inclined plate near the feed hopper.

[0014] The effect achieved by the above-mentioned components is as follows: by setting up a rubber plate, one side of the rubber plate can replace the impact plate and the inclined plate to abut against one side of the vibrating screen. In this way, when the impact plate and the inclined plate strike one side of the vibrating screen and the feed hopper, it can play a certain protective role on one side of the vibrating screen and the feed hopper, which helps to prevent damage to the vibrating screen and the feed hopper caused by long-term impact.

[0015] Preferably, a wire is installed at the bottom of one side of the impact plate, a fixed pulley is rotatably installed on one side of the bottom of the vibrating screen, the wire is disposed on the outer surface of the fixed pulley, a limit block is installed on one side of the support frame, and the wire passes through the inside of the limit block.

[0016] The effect achieved by the above components is as follows: when the conveyor belt is pulled down, the conveyor belt will move the impact plate connected to the conveyor belt toward the vibrating screen under the action of the limiting block and the fixed pulley, thereby facilitating the adjustment of the impact plate and the inclined plate through the conveyor belt.

[0017] Preferably, a rubber block is installed on the inner wall of the limiting block, and the wire is inserted into the inner wall of the rubber block.

[0018] The effect achieved by the above components is that by setting the rubber block, the inner wall of the limiting block can be replaced to abut against the outer surface of the line. When the line is pulled, the rubber block can play a certain protective role for the line, which helps to prevent the line from breaking due to excessive friction between the line and the limiting block.

[0019] Preferably, one end of the line passes through the inner wall of the rubber block and is fixedly mounted with a handle.

[0020] The effects achieved by the above components are as follows: by setting up a grip rod, which is connected to the line body, it is easier to pull the line body by the grip rod. At the same time, the grip rod can block one end of the line body, which helps to prevent the line body from detaching from the inner wall of the limiting block. When one end of the grip rod abuts against the bottom of the limiting block, the striking plate and the inclined plate move to the position furthest from the vibrating screen and the feed hopper.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by setting a striking plate and an inclined plate, and adjusting the striking plate and the inclined plate, the striking plate and the inclined plate can strike one side of the vibrating screen and the feed hopper respectively. This will cause the filter plate inside the feed hopper to vibrate, thereby promoting the material in the filter holes to leave the filter holes. This helps to prevent the filter holes from being blocked, which would lead to a decrease in the material screening efficiency. Attached Figure Description

[0030] Example 1, referring to Figures 1-2 As shown, this embodiment discloses a calcium hydroxide impurity screening device, including a support frame 1. A vibrating screen 2 (the vibrating screen 2 can be a 1040 type vibrating screen) is installed on the top of the support frame 1. A discharge hopper 3 is welded to one side of the bottom of the vibrating screen 2 and is inserted into the support frame 1. A feed hopper 4 is welded to the other side of the top of the vibrating screen 2. An auxiliary device 5 is provided on one side of the vibrating screen 2 and the feed hopper 4. The auxiliary device 5 uses a striking plate 51 and an inclined plate 512 to strike one side of the vibrating screen 2 and the feed hopper 4, causing the calcium hydroxide raw material or finished product that is blocking the filter holes to leave the filter holes. By setting the striking plate 51 and the inclined plate 512 and adjusting them, the striking plate 51 and the inclined plate 512 strike one side of the vibrating screen 2 and the feed hopper 4 respectively. This causes the filter plate inside the feed hopper 4 to vibrate, thereby causing the material in the filter holes to leave the filter holes. This helps to prevent the filter holes from being blocked, which would lead to a decrease in the material screening efficiency.

[0031] Reference Figures 2-4As shown, the auxiliary device 5 includes a striking plate 51 and an inclined plate 512. The inclined plate 512 is welded to the top of the striking plate 51. The striking plate 51 and the inclined plate 512 are respectively arranged on one side of the vibrating screen 2 and the feed hopper 4. Auxiliary plates 52 are symmetrically installed on the top of the striking plate 51. Both auxiliary plates 52 are fixedly installed at the bottom of the vibrating screen 2. Springs 53 are fixedly installed on both sides of the striking plate 51. One end of each spring 53 is fixedly installed on both sides of the vibrating screen 2. Pushing the striking plate 51 will cause the inclined plate 512 to move towards the feed hopper 4. When the striking plate 51 moves, it will compress the springs 53, causing the springs 53 to deform until the striking plate 512 is fully depressed. When the impact plate 511 and the inclined plate 512 strike one side of the vibrating screen 2 and the feed hopper 4, and the force applied to the impact plate 51 is removed, the spring 53 will reset and drive the impact plate 51 and the inclined plate 512 to automatically move away from the feed hopper 4. This process is repeated, which makes the filter plate inside the feed hopper 4 vibrate continuously, which helps to remove the material from the filter holes. The spring 53 is equipped with a round rod 54. One end of the round rod 54 is fixedly installed on one side of the impact plate 51, and the round rod 54 is slidably installed on one side of the vibrating screen 2. By setting the round rod 54, the round rod 54 can guide the spring 53, which helps to prevent the spring 53 from easily bending during deformation.

[0032] Reference Figures 2-4 As shown, a round block 56 is fixedly installed at one end of the round rod 54. The outer diameter of the round block 56 is larger than the outer diameter of the round rod 54. By setting the round block 56, the round block 56 can block one end of the round rod 54, which helps to prevent the round rod 54 from detaching from the inner wall of one side of the vibrating screen 2 due to misoperation. The same rubber plate 55 is fixedly installed on the side of the striking plate 51 and the inclined plate 512 near the feed hopper 4. By setting the rubber plate 55, one side of the striking plate 51 and the inclined plate 512 can be replaced to abut against one side of the vibrating screen 2. Thus, when the striking plate 51 and the inclined plate 512 strike one side of the vibrating screen 2 and the feed hopper 4, it can play a certain protective role on one side of the vibrating screen 2 and the feed hopper 4, which helps to prevent damage to the vibrating screen 2 and the feed hopper 4 caused by long-term striking.

[0033] Reference Figure 5 and Figure 6As shown, a wire 57 is installed at the bottom of one side of the impact plate 51, and a fixed pulley 58 is rotatably installed on one side of the bottom of the vibrating screen 2. The wire 57 is set on the outer surface of the fixed pulley 58. A limit block 59 is installed on one side of the support frame 1, and the wire 57 passes through the inside of the limit block 59. When the wire 57 is pulled down, the wire 57 will drive the impact plate 51 connected to the wire 57 to move towards the vibrating screen 2 under the action of the limit block 59 and the fixed pulley 58, thereby facilitating the passage of the wire 57. 7. Adjust the striking plate 51 and the inclined plate 512; a rubber block 510 is installed on the inner wall of the limiting block 59, and the line 57 is inserted into the inner wall of the rubber block 510. By setting the rubber block 510, it can replace the inner wall of the limiting block 59 to abut against the outer surface of the line 57. When the line 57 is pulled, the rubber block 510 can play a certain protective role for the line 57, which helps to prevent the line 57 from breaking due to excessive friction between the line 57 and the limiting block 59.

[0034] Reference Figure 5 and Figure 6 As shown, one end of the wire 57 passes through the inner wall of the rubber block 510 and is fixedly installed with a grip rod 511. By setting the grip rod 511, the grip rod 511 is connected to the wire 57, which makes it easier to pull the wire 57 through the grip rod 511. At the same time, the grip rod 511 can block one end of the wire 57, which helps to prevent the wire 57 from detaching from the inner wall of the limiting block 59. At the same time, when one end of the grip rod 511 abuts against the bottom of the limiting block 59, the striking plate 51 and the inclined plate 512 move to the position furthest from the vibrating screen 2 and the feed hopper 4.

[0035] Working principle: Pulling down the grip rod 511 causes the conveyor belt 57 to slide along the inner wall of the limiting block 59. Under the action of the fixed pulley 58, the conveyor belt 57 moves the striking plate 51 and the inclined plate 512 towards the feed hopper 4 of the vibrating screen 2. As the striking plate 51 moves, it compresses the spring 53, causing the spring 53 to deform until the rubber plate 55 on one side of the striking plate 51 and the inclined plate 512 impacts one side of the vibrating screen 2 and the feed hopper 4. Gradually removing the force applied to the grip rod 511 causes the spring 53 to return to its original position, and it then moves the striking plate 51 and the inclined plate 512 back to their original position. As the feed hopper 4 moves away automatically, the feed line 57 slides inside the limiting block 59 until one end of the handle 511 abuts against one side of the limiting block 59. This process is repeated, causing the filter plate inside the feed hopper 4 to vibrate continuously, which helps the material in the filter holes to detach from the filter holes. The rubber block 510 can replace the inner wall of the limiting block 59 and abut against the outer surface of the feed line 57. When the feed line 57 is pulled, the rubber block 510 can provide some protection for the feed line 57, which helps prevent the feed line 57 from breaking due to excessive friction between the feed line 57 and the limiting block 59.
