Description

Technical Field

[0001] This utility model relates to the field of ore grinding technology, specifically to a mining ore grinding device that avoids dust generation. Background Technology

[0002] Ore is a mineral aggregate, including metallic and non-metallic minerals. In order to extract useful minerals more easily, the ore needs to be processed by grinding it into powder to extract the useful minerals.

[0003] Application number CN202121936630.1 discloses a mining ore grinding device, relating to the field of ore processing technology. It includes a housing, a feed inlet, a grinding chamber, and a filtering and stirring chamber. The feed inlet is fixedly connected to the top of the housing, and the discharge outlet is fixedly connected to the bottom axis of the housing. The grinding chamber is located inside the housing, and a vibrating screen plate is installed at the bottom of the grinding chamber. A filtering and stirring chamber is also installed at the bottom of the vibrating screen plate. This invention uses a vibrating screen plate to perform an initial screening of the ground ore, followed by stirring the screened ore in the filtering and stirring chamber to prevent ore accumulation and clogging of the rectangular screen plate. A second screening is then performed using the rectangular screen plate, resulting in fine and uniform ore powder. A buffer plate causes the elastic block and arc-shaped return spring to deform, providing a buffering effect and effectively preventing damage to the components inside the housing from impacts by the ore.

[0004] When grinding ore into powder, the device grinds the ore into powder through a crushing and grinding chamber and a filtering and stirring chamber, and then stirs it evenly for use. During processing, impurities such as lime will adhere to the grinding and stirring chambers. When it is necessary to clean the two processing chambers of the device, because the grinding chamber and the stirring chamber are in an upper and lower structure and are isolated by a baffle, and the machine shell is a fixed structure, the cleaning water is poured into the machine through the feed port. The water source cannot reach the inner wall corners and crevices of the machine, which reduces the cleaning efficiency of the device. Utility Model Content

[0005] The purpose of this invention is to provide a mining ore grinding device that avoids dust generation and solves the problem of inconvenient cleaning of the gaps in the inner wall of the device.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a mining ore grinding device that avoids dust generation. It includes a material conveying structure and a grinding device. The material conveying structure is installed on the outer walls of both sides of the grinding device. The grinding device includes a grinding box. A fixing frame is welded to one outer wall of the grinding box. A sealing cover is hinged to the rod of the fixing frame. A rotating locking block is threaded onto the inner wall of one side of the sealing cover. The sealing cover is attached to one end of the grinding box. The rotating locking block is fixed to one outer wall of the grinding box. A feed hopper is welded to the outer wall of the sealing cover. A feed groove is formed on the overlapping surface of the feed hopper and the sealing cover. The purpose of this setup is that, during the use of the device, the ore bag opening is inserted into the feed hopper, aligned with its bottom. The sliding plate slides within the inclined groove, pressing against one end of the bag opening. The feed hopper and sliding plate secure the bag opening inside. The bottom of the bag opening is raised, allowing the ore to be poured into the feed hopper. From the bottom, the ore slides down the inclined groove to the feed trough and falls into the grinding box. A sealing cover hinged to the fixed frame is rotated to cover the opening of the grinding box. The locking block is then rotated to secure the sealing cover to the grinding box, ensuring a sealed state inside. The motor drives the shaft to rotate, causing the sleeve rod on the shaft to rotate as well. As the sleeve rod rotates, it drives the turntable and grinding blocks to agitate the ore. The turntable fixes two grinding blocks parallel to each other, and the two fixed turntables hold several grinding blocks together. One end is clamped and fixed to connect the ore. The ore is rubbed between the grinding block and the positioning grinding block to form powder. The ore is continuously stirred and rubbed in the narrow space of the grinding box to grind it into a completely powdered state. The powder with the appropriate density is filtered out through the screen plate on one side of the grinding box. Finally, the powder slides down the bottom of the inclined surface inside the discharge hopper and is discharged outward. When it is necessary to clean the inner wall of the grinding device, clean water is poured into the feed hopper. The water source enters the grinding box through the feed chute. The grinding blocks rotate and stir the clean water to wash the inner wall of the grinding box. When it is difficult to clean the gap between the positioning grinding block and the grinding block, the locking block is rotated to release the fixation of the grinding box. The sealing cover is rotated and unfolded, and one end of the grinding box is open, which facilitates the cleaning of the inner wall of the grinding box from all sides, improving the flexibility of the device.

[0008] Furthermore, a sloping groove is formed on the inner wall of the bottom of the feed hopper, and a sliding plate is slidably connected to the inner wall of the sloping groove. The feed hopper and the sliding plate are on the same horizontal line. The purpose of this arrangement is that during the use of the device, the opening of the ore bag is inserted into the feed hopper and aligned with its bottom. The sliding plate slides in the sloping groove to abut one end of the bag opening, and the feed hopper and the sliding plate fix the bag opening inside. The bottom of the bag opening is raised to pour the ore into the feed hopper.

[0009] Furthermore, a support is provided on one side of the grinding box, and a motor is fixedly installed on the upper surface of the support. The shaft of the motor is rotatably connected to the inner wall of the grinding box. The purpose of this arrangement is that during the use of the device, the motor drives the shaft to rotate, which in turn rotates the sleeve on the rod body. When the sleeve rotates, it drives the turntable and grinding blocks to stir the ore.

[0010] Furthermore, a sleeve rod is fixedly sleeved on the shaft of the motor, and two turntables are fixedly sleeved on the outer wall of the sleeve rod. Several grinding blocks are clamped onto the outer walls of the two turntables. The purpose of this arrangement is that during the use of the device, when the sleeve rod rotates, it drives the turntables and grinding blocks to stir the ore together. The turntables fix the two grinding blocks to be parallel, and the two fixed turntables clamp and fix one end of several grinding blocks to connect them. The ore is pulverized into powder through mutual friction between the grinding blocks and the positioning grinding blocks.

[0011] Furthermore, a sieve plate is fixedly installed on one inner wall of the grinding box, and the sieve plate is attached to and covers a groove on one side of the grinding box. The purpose of this arrangement is to ensure that during the use of the device…

[0012] Furthermore, several positioning grinding blocks are fixedly installed on the inner walls of the grinding box, with a certain distance between the positioning grinding blocks and the grinding blocks. A discharge hopper is welded to the outer wall of the grinding box near the screen plate. The purpose of this arrangement is that during the use of the device, after the ore is continuously stirred and rubbed in the narrow space of the grinding box and ground into a completely powdered state, the powder that has passed through the screen plate on one side of the grinding box is filtered out, and finally the powder slides downwards along the bottom of the inclined surface inside the discharge hopper and is discharged outwards.

[0013] This utility model has the following beneficial effects:

[0014] (1) By setting up a sealing cover and a feeding hopper, clean water is poured into the feeding hopper. The water source enters the grinding box through the feeding trough. The grinding blocks rotate and stir the clean water to rinse the inner wall of the grinding box. When it is difficult to clean the gap between the positioning grinding block and the grinding block, the rotating locking block is rotated to release the fixing of the grinding box. The sealing cover is rotated and unfolded, and one end of the grinding box is open, which makes it convenient to clean the inner wall of the grinding box in all directions, thus improving the flexibility of the device.

[0015] (2) By setting up the inclined groove and the sliding plate, the ore bag mouth is inserted into the feed hopper and aligned with its bottom. The sliding plate slides in the inclined groove to abut one end of the bag mouth. The bag mouth is fixed inside by the feed hopper and the sliding plate. The bottom of the bag mouth is raised and the ore is poured into the feed hopper. The ore slides down the inclined surface of the inclined groove to the feed trough and falls into the grinding box.
