Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a raw material screening device. Background Technology

[0002] In the ceramic production process, clay needs to be screened to select fine clay for producing high-quality ceramics. A ceramic clay screening device is used to screen, remove impurities, and grade clay during ceramic production. Its main function is to remove impurities (such as stones, metal particles, and coarse particles) from the clay, ensuring its fineness and uniformity, thereby improving the quality and yield of ceramic products.

[0003] In ceramic production, clay screening is a crucial pretreatment step that directly affects the forming quality and sintering performance of the green body. Currently, the most common clay screening equipment is the vibrating screen. However, due to the viscosity of the clay, it tends to accumulate in certain areas of the screen plate during the vibrating screening process, leading to localized overload, clogging of the screen plate, and affecting the overall screening efficiency.

A cleaning brush b213 is installed on the side of the cleaning shaft 210 and abuts against the bottom surface of the filter screen 204. The cleaning shaft 210 rotates to clean both the upper and lower surfaces of the filter screen 204, which can effectively prevent the filter screen 204 from clogging and improve screening efficiency. At the same time, the cleaning brush a212 and the cleaning brush b213 clean the upper and lower surfaces of the filter screen 204 respectively, ensuring that the raw materials pass through the filter screen 204 smoothly and reducing residue.

[0026] Example 2: Please refer to Figure 4 , Figure 5 and Figure 6 This embodiment provides a technical solution: a raw material screening device, including a screening section 2, a screening barrel 201, and a cleaning shaft 210. A slide rod 101 is provided on the side of the support frame 1, and a slide groove 203 is provided on the side of the screening barrel 201. The slide rod 101 passes vertically through the slide groove 203 and is slidably connected to the screening barrel 201. A spring 102 is nested on the outside of the slide rod 101. There are two springs 102. The screening barrel 201 is located between the two springs 102. The screening barrel 201 can be driven to vibrate up and down along the slide rod 101 by the vibrator 205. The springs 102 provide buffering and reset functions, making the vibration of the screening barrel 201 more stable.

[0027] A discharge port 202 is provided at the bottom of the screening barrel 201. A storage box 103 is slidably provided at the bottom of the support frame 1. The storage box 103 is located directly below the discharge port 202, which can facilitate the collection of the screened raw materials and allow the screened materials to be quickly taken out by sliding the storage box 103.

[0028] A crossbeam 206 is fixedly installed inside the screening bin 201. The fixing method is an existing detachable fixing, such as bolt connection, snap connection, etc. A power shaft 207 is horizontally rotatably installed on the top of the crossbeam 206. A motor 209 is installed on the top of the crossbeam 206. The output end of the motor 209 is connected to the power shaft 207. The motor 209 can drive the power shaft 207 to rotate, thereby driving the cleaning shaft 210 to rotate.

[0029] The cleaning shaft 210 passes vertically through the crossbeam 206 and is rotatably connected to the crossbeam 206, which ensures that the cleaning shaft 210 remains stable during rotation, avoids swaying, and improves the cleaning effect of the cleaning brushes a212 and b213 on the filter screen 204.

[0030] Two power bevel teeth 208 are integrally arranged on the side of the power shaft 207. The two power bevel teeth 208 are arranged in a mirror image around the center of the power shaft 207. A transmission bevel tooth 211 is provided on the top of the cleaning shaft 210. The number of teeth of the two power bevel teeth 208 is half. The two power bevel teeth 208 are alternately engaged with the transmission bevel teeth 211. Through the meshing of the power bevel teeth 208 and the transmission bevel teeth 211, the cleaning shaft 210 is intermittently rotated in opposite directions, thereby driving the cleaning brush a212 and the cleaning brush b213 to clean the filter screen 204 in an intermittent manner.

[0031] There are three cleaning brushes a212, which are arranged in a central rotational symmetric structure around the rotation center of the cleaning shaft 210. There are also three cleaning brushes b213, which are arranged in a central rotational symmetric structure around the rotation center of the cleaning shaft 210. The three symmetrically distributed cleaning brushes a212 and b213 can evenly cover the upper and lower surfaces of the filter screen 204, ensuring thorough cleaning and improving the cleanliness of the filter screen 204.

[0032] A stirring rod 214 is provided on the side of the cleaning shaft 210. There are three stirring rods 214. The three stirring rods 214 are arranged in a central rotational symmetric structure around the rotation center of the cleaning shaft 210. The stirring rods 214 can stir the raw materials in the screening barrel 201 during the rotation process, prevent the raw materials from accumulating, improve the screening efficiency, and promote the uniform passage of the raw materials through the filter screen 204.

[0033] Working principle: First, the raw material to be screened is poured into the screening barrel 201. The vibrator 205 is started, causing the screening barrel 201 to vibrate up and down along the slide bar 101. At the same time, the spring 102 provides buffering and reset functions, making the vibration more stable. During the vibration process, the raw material is screened through the filter screen 204. The material that meets the requirements falls from the discharge port 202 into the collection box 103, while larger particles remain in the screening barrel 201. Simultaneously, the motor 209 is started, driving the power shaft 207 to rotate. The two power bevel teeth 208 on the power shaft 207 alternately mesh with the transmission bevel teeth 211 at the top of the cleaning shaft 210, making... The cleaning shaft 210 generates intermittent forward and reverse rotation. The cleaning shaft 210 drives the cleaning brushes a212 and b213 to clean the upper and lower surfaces of the filter screen 204 respectively, preventing clogging and ensuring screening efficiency. In addition, the stirring rod 214 on the cleaning shaft 210 continuously stirs the raw materials in the screening barrel 201 during rotation, preventing accumulation and promoting the uniform passage of raw materials through the filter screen 204. After screening is completed, the vibrator 205 and motor 209 are turned off, and the sliding collection box 103 removes the screened material, completing the entire screening process. This device effectively improves screening efficiency by combining vibration screening with automatic cleaning.
