Technical Field

[0001] This utility model relates to the field of abrasive equipment technology, and in particular to an abrasive equipment. Background Technology

[0002] In existing technology, abrasive equipment includes a sieve and a pin mill. The sieve is located on the ground, and the pin mill is located on an abrasive platform. After the first material bucket is filled with material, a first elevator is used to lift the first material bucket onto the sieve for sieving. The sieved material is then loaded into a second material bucket, which is then lifted by a second elevator onto the pin mill for pin milling. This process requires the material to be lifted twice before entering the pin mill, which is cumbersome and reduces abrasive efficiency.

[0003] Therefore, there is an urgent need for an abrasive device to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this invention is to provide an abrasive device to at least solve one of the above-mentioned problems.

[0012] Furthermore, the sieving machine also includes a moving component, which includes a slider and a slide rail. One of the slider and the slide rail is disposed on the sieving base, and the other is configured to be disposed on the abrasive platform. The slider is slidably disposed on the slide rail.

[0013] Furthermore, the abrasive equipment also includes a sealing cover, which is disposed on the sieve feed inlet. The sealing cover has a sealing opening that communicates with the sieve feed inlet. The discharge port of the material hopper can be inserted into the sealing opening and sealed by the sealing cover.

[0014] Furthermore, the needle mill also includes a first level gauge and a second level gauge, which are spaced apart along the height direction on the feeding hopper.

[0015] Furthermore, the abrasive device also includes a clamp, through which the screen cylinder and the feed hopper are connected.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] like Figures 1-10As shown, this embodiment provides an abrasive device 100, which is located inside a grinding chamber 300, specifically on an abrasive platform 400 within the grinding chamber 300. The abrasive device 100 includes a sieve 1, a pin mill 2, and an elevator 4. Both the pin mill 2 and the sieve 1 are installed on the abrasive platform 400, and the sieve hopper 12 of the sieve 1 is directly connected to the feeding hopper 22 of the pin mill 2. The elevator 4 is used to lift the material-filled bucket 200 to the connection with the sieve 1. After being sieved by the sieve 1, the material falls directly into the pin mill 2 for pin grinding. The material-filled bucket 200 only needs to be lifted by the elevator 4 to the sieve inlet 1211 of the sieve 1, eliminating the need for two lifting operations, simplifying the operation steps, and improving the abrasive efficiency.

[0041] The top of the crushing chamber 300 has an obstacle zone 301. If the existing sieve bucket of the sieve machine and the feed hopper of the pin mill are directly connected, and considering the installation position of the grinding equipment 100 in the crushing chamber 300, the sieve machine 1 and the pin mill 2 will interfere with the obstacle zone 301 in the height direction after installation. Furthermore, the sieve machine 1 and the pin mill 2 will exceed the lifting range of the elevator 4 in the height direction after installation. Therefore, it is necessary to modify the sieve machine 1 and / or the pin mill 2 so that they do not interfere with the obstacle zone 301 and are within the lifting range of the elevator 4.

[0042] like Figures 1-4 As shown, the sieve 1 includes a sieve base 11 and a sieve hopper 12. The sieve hopper 12 includes a feeding part 121, a screen 122 and a sieve cylinder 123. The feeding part 121 has a sieve inlet 1211. The screen 122 is disposed on the sieve inlet 1211. The sieve cylinder 123 is connected to the feeding part 121 and is disposed on the sieve base 11. The needle mill 2 includes a needle mill frame 21 and a feeding hopper 22. The feeding hopper 22 is disposed on the needle mill frame 21. The sieve cylinder 123 has a sieve outlet 1231. The feeding hopper 22 has a feeding inlet 221 and is connected to the sieve outlet 1231. The sieve base 11 can be partially inserted into the needle mill frame 21. The elevator 4 can lift the material-filled bucket 200 to the sieve inlet 1211. The sieve hopper 12 of the sieve machine 1 has its lower feed hopper removed, shortening the overall height of the grinding equipment 100 to avoid interference with the obstruction zone 301 of the crushing chamber 300. The sieve discharge port 1231 of the sieve machine 1 is directly connected to the feed inlet 221 of the needle mill 2, so that the material falls directly into the needle mill 2 for grinding after being sieved by the sieve machine 1. The material bucket 200 only needs to be lifted to the sieve feed inlet 1211 of the sieve machine 1 by the elevator 4. The material does not need to be lifted twice, simplifying the operation and improving the grinding efficiency.

[0043] To facilitate the description of the relative position of the abrasive device 100, the following will be used: Figure 1 , Figure 2 and Figure 7 The X direction is defined as the first direction, and... Figure 1 , Figure 2 and Figure 7 The Y-direction in the equation is defined as the second direction. Figure 1 , Figure 2 and Figure 7 The Z-direction is defined as the third direction, with the first direction, second direction, and third direction set perpendicularly to each other. In this embodiment, the third direction is the height direction.

[0044] Furthermore, the abrasive device 100 also includes a sealing cover 3, which is disposed on the sieve feed inlet 1211. The sealing cover 3 has a sealing port 31, which is connected to the sieve feed inlet 1211. The discharge port 202 of the material hopper 200 can be inserted into the sealing port 31 and sealed by the sealing cover 3.

[0045] Specifically, after the discharge port 202 of the material bucket 200 is inserted into the sealing port 31, the discharge port 202 and the sealing port 31 are interference fit to prevent gaps from appearing between the discharge port 202 and the sealing port 31, so as to prevent the material from flowing out from the gap between the discharge port 202 and the sealing port 31.

[0046] More specifically, the sealing cap 3 is made of silicone material, and the seal between the discharge port 202 and the sealing port 31 is achieved by the elasticity of the silicone material of the sealing cap 3.

[0047] Furthermore, the sieve feed inlet 1211 is conical, and the screen 122 is also conical, meaning that the area where the material enters is relatively large, which facilitates the material entering the sieve feed inlet 1211 and the screen 122.

[0048] Furthermore, the screen cylinder 123 is cylindrical and is directly connected to the feeding hopper 22.

[0049] Furthermore, the needle mill 2 also includes a first level gauge 23 and a second level gauge 24, which are spaced apart along the height direction on the feeding hopper 22. Specifically, the first level gauge 23 is located at a first preset position on the feeding hopper 22 and can detect whether the material level in the feeding hopper 22 has reached the first preset position. Correspondingly, the second level gauge 24 is located at a second preset position on the feeding hopper 22 and can detect whether the material level in the feeding hopper 22 has reached the second preset position. The height of the first preset position is greater than the height of the second preset position. If the first level gauge 23 detects that the material level in the feeding hopper 22 has reached the first preset position, it means that there is too much material in the feeding hopper 22, so the feeding of material into the feeding hopper 22 is stopped; if the second level gauge 24 detects that the material level in the feeding hopper 22 has reached the second preset position, it means that there is too little material in the feeding hopper 22, so the feeding hopper 22 needs to be fed to prevent the needle mill 2 from blocking or running dry, and to improve the needle mill efficiency.

[0050] Specifically, both the first level gauge 23 and the second level gauge 24 are capacitive proximity switches, specifically model CJM30-10A2-S level sensors.

[0051] Furthermore, the material hopper 200 includes a hopper body 201 and a switch valve 203. The hopper body 201 has a hopper outlet 202. The switch valve 203 is located near the hopper outlet 202. The switch valve 203 can block or open the hopper outlet 202 to determine whether the material hopper 200 supplies material to the screening machine 1.

[0052] In this embodiment, the switching valve 203 can be a butterfly valve.

[0053] Furthermore, the abrasive device 100 also includes a clamp 5, through which the screen cylinder 123 and the feeding hopper 22 are connected. This arrangement ensures that the relative positions of the screen hopper 12 and the feeding hopper 22 remain unchanged, allowing the material to smoothly enter the feeding hopper 22 from the screen hopper 12.

[0054] like Figures 5-8 As shown, the sieve 1 also includes a moving component 13, which is used to move the sieve 1 so as to clean and maintain the sieve hopper 12 of the sieve 1 and the feeding hopper 22 of the needle mill 2.

[0055] Furthermore, the moving component 13 includes casters 131, which are disposed on the bottom surface of the sieve base 11. This arrangement facilitates pushing the sieve base 11, thereby moving the sieve hopper 12 away from the feed hopper 22, so as to clean and maintain the sieve hopper 12 of the sieve machine 1 and the feed hopper 22 of the needle mill 2. In this embodiment, the moving direction of the sieve machine 1 is the first direction.

[0056] Furthermore, the moving component 13 also includes a positioning wheel 132, which is located on the side of the screening base 11. A positioning groove is provided on the needle mill frame 21, and the positioning wheel 132 is rotatably disposed in the positioning groove. The positioning wheel 132 and the positioning groove play a positioning and guiding role in the movement of the screening machine 1.

[0057] Furthermore, there are multiple positioning wheels 132, which are distributed on two opposite sides of the screening base 11. This arrangement makes the screening machine 1 move more stably.

[0058] In other alternative embodiments, the moving component 13 may also include a slider and a slide rail, one of which is disposed on the screening base 11 and the other is configured to be disposed on the abrasive platform 400, with the slider slidably disposed on the slide rail. The arrangement of the slider and slide rail also enables the movement of the screening machine 1.

[0059] Furthermore, the power source for moving the moving component 13 is not limited. The screening base 11 can be pushed manually, or a cylinder or the like can be used to move the screening base 11, as long as the movement of the screening machine 1 can be achieved.

[0060] like Figures 7-10 As shown, the elevator 4 has both lifting and rotating functions to lift the material bucket 200 onto the screening machine 1. The elevator 4 includes a lifting base 46, a lifting seat 42, and a clamping member 43. The lifting seat 42 is vertically mounted on the lifting base 46, and the clamping member 43 is rotatably mounted on the lifting seat 42 in a first rotation direction. The clamping member 43 can clamp the material bucket 200. When the lifting seat 42 rises, it causes the clamping member 43 and the material bucket 200 to rise; when the clamping member 43 rotates in the first rotation direction, the material bucket 200 is inverted so that the bucket outlet 202 can be inserted into the sealing port 31.

[0061] Furthermore, the hoist 4 also includes a first rotating shaft 44, which is rotatably mounted on the lifting seat 42, and a clamping member 43 is mounted on the first rotating shaft 44. When the first rotating shaft 44 rotates, it drives the clamping member 43 to rotate in a first rotation direction.

[0062] Furthermore, the elevator 4 also includes an elevator frame 41, which is rotatably mounted on the elevator base 46 in a second rotation direction. The lifting seat 42 is vertically mounted on the elevator frame 41. The elevator frame 41 rotates in the second rotation direction, causing the lifting seat 42, the clamping member 43, and the material bucket 200 to rotate in the second rotation direction, so that the elevator 4 avoids the screening machine 1 and / or the needle mill 2 during the process of lifting the material bucket 200, and ensures that the material bucket 200 moves above the screening inlet 1211.

[0063] Furthermore, the hoist 4 also includes a second rotating shaft 45, which is rotatably mounted on the hoisting base 46, and the hoisting frame 41 is rotatably mounted on the second rotating shaft 45.

[0064] In this embodiment, the axial direction of the first rotating shaft 44 is perpendicular to the axial direction of the second rotating shaft 45. The axis of the second rotating shaft 45 extends along a third direction, and the second rotation direction is the rotation direction on the plane formed by the first and second directions. Specifically... Figure 7 The counterclockwise direction.

[0065] In this embodiment, the power source for the lifting of the lifting seat 42, the power source for the rotation of the first rotating shaft 44, the power source for the rotation of the second rotating shaft 45, and the power source for the clamping of the clamping member 43 are not limited, and commonly used structures in the prior art can be selected.

[0066] In this embodiment, the hoist 4 is existing technology, and the model of the hoist 4 is PTH250. No modification was made to the hoist 4.

[0067] The lifting process of the elevator 4 lifting the material bucket 200 in this embodiment is as follows:

[0068] Clamping component 43 clamps the bucket 200 with the discharge port 202 facing upwards, and the butterfly valve is closed;

[0069] The lifting seat 42 rises on the lifting frame 41, causing the material bucket 200 with the discharge port 202 facing upwards to rise to the first preset height;

[0070] The first rotating shaft 44 rotates in the first rotation direction, causing the clamping member 43 and the material bucket 200 to rotate, so that the material bucket 200 is inverted and the bucket outlet 202 faces downward.

[0071] The lifting seat 42 continues to rise on the lifting frame 41, driving the material bucket 200 with the discharge port 202 facing downwards to rise to the second preset height;

[0072] The second rotating shaft 45 rotates in the second rotation direction, driving the lifting frame 41, lifting seat 42, clamping member 43 and the material bucket 200 with the discharge port 202 facing downward to rotate, so as to avoid the sieve machine 1 and / or needle mill 2.

[0073] The lifting seat 42 continues to rise on the lifting frame 41, driving the material bucket 200 with the bucket outlet 202 facing downwards to rise to the third preset height. At this time, the bucket outlet 202 is higher than the sieve inlet 1211.

[0074] The second rotating shaft 45 rotates in the second rotation direction, driving the lifting frame 41, lifting seat 42, clamping member 43 and the material bucket 200 with the bucket discharge port 202 facing downward to rotate, so that the bucket discharge port 202 is directly opposite to the sieve feed port 1211.

[0075] The lifting seat 42 descends on the lifting frame 41, causing the bucket discharge port 202 to insert into the sealing port 31.

[0076] Although the present invention has been described in detail above with general descriptions, specific embodiments, and experiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
