Description

Technical Field

[0001] The utility model relates to the technical field of crushing and grinding machines, in particular to a raw material crushing and grinding machine. Background Art

[0002] Ceramics is a general term for pottery and porcelain. Ceramics are products made from clay and various natural minerals through crushing, mixing, molding and calcining. Therefore, the raw materials need to be crushed during the ceramic preparation process, but ordinary crushing devices do not crush completely, and the feed port is in an open state for a long time. A large amount of granular dust generated after the raw materials are crushed will float out through the feed port and spread to the space where the crushing device is placed. It will enter the human respiratory tract with human breathing. If the dust prevention measures in the space are incomplete, long-term inhalation of granular dust may lead to dust-induced upper respiratory tract occupational diseases, and in severe cases, it may even turn into occupational respiratory cancer. Common dust reduction settings generally add a switch component at the entrance of the device. When feeding, the switch component needs to be turned on, which increases the operating steps during crushing. In addition, during crushing, the device will be displaced due to vibration, and sometimes the bottom of the device and the ground will be damaged;

[0003] In the prior art, for example, announcement number CN217796554U proposes a ceramic raw material crushing device for ceramic production. This technical solution relates to the technical field of ceramic production, and specifically refers to a ceramic raw material crushing device for ceramic production. It comprises a bottom plate, a crushing box on the top of the bottom plate, and the crushing box comprises a feeding bin, a primary crushing bin, a secondary crushing bin, and a collecting bin. There are two dust shielding assemblies on the top of the crushing box, and the dust shielding assembly comprises a fixed block, and a connecting clamp is provided on one side of the fixed block, and a dust shielding plate is provided in the connecting clamp, and torsion springs are provided on both sides of the connecting clamp. There are two crushing wheels in the primary crushing bin, and one end of one of the crushing wheels has a motor 1, and a guide plate is provided in the secondary crushing bin, and a grinding assembly is provided at the bottom of the guide plate, and the grinding assembly comprises a grinding plate, and a grinding cone is provided in the grinding plate, and a frame plate is provided at the bottom of the grinding cone, and a motor 2 is provided at the bottom of the frame plate, and a drawer is provided in the collecting bin, and a stable support assembly is provided at the bottom of the bottom plate. The utility model provides a ceramic raw material crushing device for ceramic production, which can reduce dust generation, facilitate feeding, and reduce damage to the bottom of the device and the ground;

[0004] However, since there is no filtering device inside the ceramic raw material grinding device of the prior art solution, when the device grinds and grinds the ceramic raw materials, some incompletely ground ceramic fragments will be mixed in the completely ground ceramic fragments, which may affect the production of ceramic products and even affect the quality of the finished ceramic products;

[0005] In order to solve the above problems, the present application proposes a raw material crushing and grinding machine. Utility Model Content

[0006] The utility model is intended to provide a raw material crushing and grinding machine, which is mainly used to solve the problem that the existing ceramic raw material crushing device has no filtering device inside, resulting in some incompletely crushed ceramic fragments being mixed in the completely crushed ceramic fragments when the device is operating, thus affecting the production of ceramic finished products.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0008] A raw material crushing and grinding machine comprises a crushing box, a drawer, a first crushing bin, a second crushing bin and a grinding cone installed inside the second crushing bin, wherein the interior of the crushing box is located above the drawer and is slidably connected to a frame, a filter is fixedly connected to the inner wall of the frame, a vibration assembly is fixedly connected to the bottom of the grinding cone, an inspection door is hinged on one side of the crushing box, an L-shaped block is fixedly connected to one side of the inspection door, a limit block matching the L-shaped block is rotatably connected to one side of the crushing box, and one side of the frame is arranged to abut the inspection door.

[0009] The working principle and beneficial effects of the utility model:

[0010] 1. Working principle: When using the device, connect the device to an external power supply, start the device, add the ceramic raw materials to be crushed and ground into the crushing box, and the ceramic raw materials will fall onto the filter after being crushed and ground by the first crushing bin and the second crushing bin. After the ceramic raw materials are filtered by the filter, fine ceramic debris will fall into the drawer, while large pieces of ceramic fragments will remain on the filter. After opening the inspection door, the staff can clean out the ceramic fragments on the filter, and then re-perform the crushing operation to obtain completely crushed ceramic raw materials.

[0011] 2. Beneficial effects: Through the filter screen arranged inside the crushing box, the ceramic raw materials fall onto the filter screen after being crushed and ground twice, and the ceramic raw materials can be filtered, thereby effectively preventing incompletely crushed ceramic fragments from mixing in the completely crushed ceramic fragments. The vibration component arranged at the bottom of the grinding cone can make the filter screen vibrate to a certain extent, so that the filter screen has a higher filtering efficiency for the ceramic raw materials, and can effectively reduce the clogging of the filter screen, thereby effectively improving the crushing efficiency of the device for the ceramic raw materials.

[0012] Preferably, the vibration assembly includes a connecting rod fixedly connected to the bottom of the grinding cone, the lower end of the connecting rod is fixedly connected to an impact block, and the top of the filter is fixedly connected to a plurality of vibration blocks matching the impact block, and the vibration blocks are equidistantly distributed on the filter in a circular array. During operation of the device, the rotation of the grinding cone can perform secondary grinding on the ceramic raw material. While the grinding cone rotates, it can drive the impact block at its bottom to operate in a circle inside the crushing box through the connecting rod. While the impact block operates in a circle inside the crushing box, it will hit the vibration block on the filter, causing the filter to vibrate to a certain extent, thereby making the filter more efficient in filtering ceramic debris and effectively reducing the possibility of filter blockage.

[0013] Preferably, an observation port is provided on the inspection door, and an observation window is fixedly connected to the inner wall of the observation port, and the observation window is transparent. The observation window can be made of tempered glass. Since the transparency of tempered glass is relatively high, the staff can observe the retention amount of ceramic fragments on the filter screen through the observation window provided on the inspection door, thereby facilitating people to clean the ceramic fragments on the filter screen in time, thereby effectively ensuring the normal operation of the device.

[0014] Preferably, guide blocks are fixedly connected to both sides of the frame, and guide grooves matching the guide blocks are provided on both sides of the inner wall of the crushing box. The guide blocks arranged on both sides of the frame and the guide grooves provided on the inner wall of the crushing box can guide the frame better when people disassemble and assemble the frame, thereby making it more convenient for people to disassemble and assemble the frame, and can provide better support for the frame, thereby making the device more stable during operation.

[0015] Preferably, the number of connecting rods is three, and the connecting rods are equidistantly distributed in a circular array at the bottom of the grinding cone. By setting the number of connecting rods at the bottom of the grinding cone to three, the lower ends of the three connecting rods are fixed with impact blocks, which can effectively increase the impact frequency of the impact blocks on the filter screen during the operation of the device, thereby making the vibration frequency of the filter screen higher during the operation of the device, and further making the filter screen more efficient in filtering ceramic debris.

[0016] Preferably, the corners of the L-shaped card block are all rounded, so that people can turn the inspection door and open it more easily by pulling the L-shaped card block. By setting the corners of the L-shaped card block to be rounded, people's hands can be more comfortable when pulling the L-shaped card block, and the corners of the L-shaped card block can be effectively prevented from scratching people's hand skin.

[0017] Preferably, a sealing strip is fixedly connected to the edge of the inspection door close to the crushing box. The sealing strip can be made of rubber material. Since rubber material has good sealing properties, the sealing strip arranged on one side of the inspection door allows people to close the inspection door and the device to have better sealing properties when operating normally, so that ceramic powder will not be discharged through the gap between the inspection door and the crushing box.
