Abstract

This utility model provides a fire-retardant coating processing and grinding device, including a fire-retardant coating grinding shell, and further including: a screening structure disposed within the fire-retardant coating grinding shell; and a grinding structure disposed within the screening structure. The rotating screening cylinder facilitates better screening of the ground material, preventing incompletely ground material from falling into the powder collection box, thus ensuring better grinding quality. As the screening cylinder rotates, the incompletely ground material rotates upwards. When it reaches a high position, the material particles roll downwards, falling between the grinding roller and grinding blocks for re-grinding. This facilitates better refeeding of incompletely ground material, allowing for cyclic grinding and ensuring the fire-retardant coating material is completely ground. The cleaning brush helps prevent powder from clogging the mesh of the screening cylinder, thus affecting the screening efficiency.

Description

Technical Field

[0001] This utility model relates to the field of fireproof coating processing technology, and in particular to a fireproof coating processing grinding device. Background Technology

[0002] Fire-retardant coating processing refers to the process of turning fire-retardant coating materials into coatings suitable for various substrate surfaces through specific processes and technologies. Fire-retardant coatings are special coatings with fire-retardant properties that can slow the spread of fire during a fire, buying valuable time for evacuation and firefighting. During the processing of fire-retardant coatings, grinding equipment is typically used to grind the materials.

[0003] However, conventional grinding equipment often lacks sufficient grinding efficiency, resulting in incomplete grinding of some fire-retardant coating materials. This leads to the presence of large particles in the ground fire-retardant coating powder, affecting the overall quality of the fire-retardant coating. Therefore, ensuring the complete grinding of fire-retardant coating materials and guaranteeing the grinding quality is a crucial issue that needs to be addressed in the design of fire-retardant coating processing grinding equipment. Utility Model Content

[0005] This utility model solves the above-mentioned technical problems through the following technical solutions:

[0006] This utility model provides a fire-retardant coating processing and grinding device, including a fire-retardant coating grinding shell, and further comprising:

[0007] A sieving structure is disposed within the fire-retardant coating grinding housing;

[0008] A grinding structure is provided inside a sieving structure, and the sieving structure and the grinding structure cooperate with each other to perform cyclic grinding;

[0011] In this technical solution, the support plate uses the shielding shell to fix and support the fireproof coating grinding shell in the inner ring of the rotating connecting ring.

[0012] Preferably, the grinding structure includes a fixed housing, a feeding housing, a grinding roller, grinding blocks, a feeding housing, a rotating rod, and a motor. The fixed housing is fixedly connected to the inner wall of the fire-retardant coating grinding housing. The feeding housing is fixedly connected to the bottom side wall of the fixed housing.

[0013] In this technical solution, the motor rotates to drive the rotating rod to rotate, and the rotating rod drives the grinding roller to rotate. The rotating grinding roller, together with the grinding blocks on both sides, grinds the material of the fireproof coating that enters.

[0014] Preferably, the grinding roller is located between two grinding blocks, the grinding roller and the two grinding blocks cooperate with each other, a rotating gear is fixedly connected to the side wall of the rotating rod, the rotating gear is located inside the shielding housing, and the rotating gear and the transmission gear mesh with each other.

[0015] In this technical solution, the rotating gear rotates along with the rotating rod, and the rotating gear drives the transmission gear to rotate.

[0016] Preferably, the screening structure includes a screening cylinder, a fixed ring, a baffle, a rotating connecting ring, a rotating toothed groove, and a rotating ring. Two fixed rings are fixedly connected to both ends of the screening cylinder. A rotating connecting ring is fixedly connected to the side wall of the fixed ring at one end of the screening cylinder. The rotating connecting ring is rotatably connected to the side wall of the back of the fire-retardant coating grinding shell.

A rotating ring is fixedly connected to the side wall of the fixed ring at the other end of the screening cylinder. The rotating ring is rotatably connected to the inner side wall of the fire-retardant coating grinding shell. Baffles are fixedly connected at equal intervals on the inner side wall of the screening cylinder.

[0017] In this technical solution, the rotating connecting ring drives the fixed ring to rotate, and the fixed ring drives the screening cylinder to rotate. The rotating screening cylinder screens the ground material, so that the material that is completely ground into powder is screened off, while the incompletely ground material particles continue to remain inside the screening cylinder. As the screening cylinder rotates, it is driven upward by the baffle. When it rotates to a high position, the baffle tilts downward, and the material particles on the inner wall of the baffle roll down along the tilted baffle and return to the feed housing.

The fixing plate is fixedly connected to the top inner side wall of the fireproof coating grinding shell, and the connecting rod is fixedly connected to the side wall of the fixing plate. The other end of the connecting rod is fixedly connected to the cleaning brush.

[0025] Preferably, the sidewall of the cleaning brush is attached to the sidewall of the screening cylinder.

[0026] In this technical solution, as the screening cylinder rotates, the cleaning brush cleans the screening cylinder, preventing powder from clogging the mesh of the screening cylinder and affecting the screening efficiency of the screening cylinder.

[0027] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0028] The positive and progressive effects of this utility model are as follows:

[0029] 1. The grinding material is sieved by a rotating sieve cylinder, so that the material that is completely ground into powder is sieved off and falls into the powder collection box for collection, while the incompletely ground material particles remain inside the sieve cylinder. This facilitates better sieving of the ground material and prevents incompletely ground material from falling into the powder collection box, thus better ensuring the grinding quality of the material.

[0030] 2. As the screening cylinder rotates, the incompletely ground material is driven upward by the baffle. When it reaches a high position, the baffle tilts downward, and the material particles on the inner side wall of the baffle roll down along the tilted baffle and return to the feed housing. They fall between the grinding roller and the grinding block for re-grinding, which facilitates the refeeding of the incompletely ground material and allows for the cyclic grinding of the incompletely ground material, ensuring that the fireproof coating material is completely ground.

[0031] 3. The cleaning brush of this application is attached to the side wall of the screening cylinder. As the screening cylinder rotates, the cleaning brush cleans the screening cylinder, which helps to prevent powder from clogging the mesh of the screening cylinder and affecting the screening efficiency of the screening cylinder.

As the screening cylinder 801 rotates, it is driven upward by the baffle 803. When it reaches a high position, the baffle 803 tilts downward, and the material particles on the inner wall of the baffle 803 roll down along the tilted baffle 803 and return to the feed housing 905.

[0051] The rotating tooth groove 805 and the transmission gear 14 mesh with each other.

[0052] The transmission gear 14 rotates within the rotating tooth groove 805, causing the rotating connecting ring 804 to rotate.

Fixed ring 802 drives screening cylinder 801 to rotate. The rotating screening cylinder 801 screens the ground material, so that the material that is completely ground into powder is screened off and falls into powder collection box 3 for collection. The material particles that are not completely ground continue to remain inside screening cylinder 801. As screening cylinder 801 rotates, it is driven to rotate upward by baffle 803. When it rotates to a high position, baffle 803 tilts downward. The material particles on the inner side wall of baffle 803 roll down along the tilted baffle 803 and return to the feed housing 905. They fall between grinding roller 903 and grinding block 904 for re-grinding, so that the fireproof coating material is completely ground.
