Description

Technical Field

[0001] This utility model relates to the technical field of ceramic tube shell production equipment, specifically a device for recovering slurry from ceramic tube shells. Background Technology

[0002] Surface mount sensors are packaged using ceramic housings. The manufacturing process for ceramic housings involves: casting, drilling, printing, adhesive coating, stacking, thermal cutting, and sintering. Conductivity in the ceramic housing is typically achieved through upper and lower layer circuit printing, slurry filling holes, or slurry coating holes. Applying slurry to the surface of the printed raw ceramic sheet is a crucial step in the manufacturing of ceramic housings.

[0003] According to Chinese Patent Application No. CN202222474862.0, a device for recovering slurry from ceramic tube shells belongs to the technical field of ceramic tube shell production equipment. It includes a slurry-coating platform with an internal air extraction chamber. A slurry-coating mask is located within the air extraction chamber and is flush with the platform surface. The mask has a first slurry flow hole. A support plate is located below the mask, with a second slurry flow hole on the support plate. An air passage plate is located below the support plate, with a receiving groove in the middle. The sidewall of the receiving groove is fixed to the air passage plate, and a gap exists between the receiving groove and the support plate. Through holes are provided around the air passage plate. An air extraction hole is located at the bottom of the air extraction chamber and is connected to an air extraction pipe. This invention solves the problem of recycling excess slurry, greatly reducing raw material waste and saving tooling cleaning time. It also has a simple structure and good practicality. When the above-mentioned device is in use, various impurities will be mixed into the slurry. If these impurities are not effectively filtered and removed during the recycling process, they will seriously affect the quality of the ceramic tube shell after being reused, resulting in product defects. Therefore, a slurry recycling device for ceramic tube shells is proposed to solve the above-mentioned problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a device for recycling slurry on ceramic tube shells, addressing the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a recycling device for slurry on ceramic tube shells, including a slurry platform, an installation hole on the slurry platform, an air circuit plate connected in the installation hole, a material receiving groove on the air circuit plate, a filter screen plate connected to the inner wall of the material receiving groove, and a scraping mechanism provided on the air circuit plate.

[0006] The scraping mechanism includes a lead screw, which is rotatably connected to the inner right side of the air passage plate via a bearing. A sliding plate is threaded onto the outer wall of the lead screw, and a scraper is connected to the bottom of the sliding plate. The bottom of the scraper is in contact with the upper surface of the filter screen plate. During the slurry application process, excess slurry falls into the receiving trough through the slurry flow hole. The filter screen plate intercepts impurities in the slurry, ensuring the purity of the recovered slurry. The lead screw rotation drives the sliding plate and scraper to move along the surface of the filter screen plate, automatically scraping off the adhering impurities and residual slurry, avoiding the tediousness of manual cleaning, preventing filter screen plate clogging, improving recovery efficiency, and reducing slurry waste.

[0007] Preferably, the scraping mechanism further includes an electric motor connected to the inner left side of the air circuit plate, and the left end of the lead screw is connected to the output end of the electric motor. By starting the electric motor, the lead screw is driven to rotate, providing power to the lead screw and realizing the automatic reciprocating motion of the scraper.

[0008] Preferably, the inner wall of the back of the air passage plate is provided with a sliding groove, and the back of the slide plate is slidably connected in the sliding groove. The sliding groove limits the slide plate, ensuring that the slide plate and scraper move smoothly in a straight line, avoiding incomplete scraping or damage to the filter plate due to deviation, and ensuring the accuracy and reliability of the scraping action.

[0009] Preferably, the bottom of the receiving trough is connected to a discharge pipe, the bottom end of which passes through the air passage plate and extends downward. A solenoid valve is installed on the discharge pipe, which is connected to a recycling container. The solenoid valve controls the timing of slurry discharge, facilitating the centralized collection of filtered pure slurry and realizing the recycling of slurry.

[0010] Preferably, a slurry-coating mask is connected inside the mounting hole and is located above the air passage plate. The top of the slurry-coating mask has several slurry flow holes, which limit the flow path of the slurry, ensure accurate slurry placement, and facilitate guiding the slurry into the receiving tank to prevent slurry from dripping and contaminating the equipment.

[0011] Preferably, the bottom of the air circuit board is provided with an air extraction hole, and the bottom of the air circuit board is connected to an air extraction pipe, which is connected to the air extraction hole. The air extraction pipe is connected to an external negative pressure device to form a downward airflow during slurry application, which accelerates the slurry through the slurry flow hole and falls into the receiving trough. A gap is left between the receiving trough and the slurry coating mask to ensure the smooth flow of the air extraction path. The air circuit board is provided with a through hole so that the air path reaches the air extraction pipe through the through hole.

[0012] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0013] 1. This is a ceramic tube shell slurry recycling device. During the slurry coating process, excess slurry falls into the receiving tank through the slurry flow hole. The filter screen plate intercepts impurities in the slurry to ensure the purity of the recycled slurry. By starting an electric motor to drive the lead screw to rotate, the lead screw rotates and drives the slide plate and scraper to move along the surface of the filter screen plate, automatically scraping off the adhering impurities and residual slurry, avoiding the tedious manual cleaning, and at the same time preventing the filter screen plate from clogging, improving recycling efficiency and reducing slurry waste.

[0014] 2. This ceramic tube shell slurry recycling device connects to a recycling container via a discharge pipe, and a solenoid valve controls the timing of slurry discharge, facilitating the centralized collection of filtered pure slurry and realizing the recycling of slurry.

A scraper 73 is connected to the bottom of plate 72. The bottom of scraper 73 is in contact with the upper surface of filter plate 6. During the slurry application process, excess slurry falls into the receiving trough 5 through the slurry flow hole 3.

A gap is left between the receiving trough 5 and the slurry-coating mask 2 to ensure unobstructed air extraction. A through hole is opened on the air passage plate 4, allowing the air to reach the air extraction pipe 11 through the through hole.
