Description

Technical Field

[0001] The present invention relates to the technical field of gas cleaning equipment, and specifically to a material cleaning device for the production of mechanical and electrical parts. Background Art

[0002] In the patent application with the application publication number CN220559960U, it includes a cleaning box, a sealing door provided on one side of the cleaning box, a partitioning unit provided inside the cleaning box, a dust removal and drying chamber located on one side of the partitioning unit, and a cleaning chamber located on the other side of the partitioning unit. It further includes: a transportation unit, where the transportation unit includes a transportation member provided inside the cleaning box; a dust removal and drying unit, where the dust removal and drying unit includes a dust removal and drying member provided on the top wall of the dust removal and drying chamber and a first material turning member provided below the dust removal and drying member; a cleaning unit, where the cleaning unit includes a cleaning member provided on the top of the cleaning chamber and a second material turning member provided below the cleaning member. The advantages are as follows: By setting the partitioning unit, the internal space of the cleaning box is divided into a dust removal and drying chamber and a cleaning chamber, which facilitates the cleaning unit to wash the components in the cleaning chamber. When transporting the components through the transportation unit, open the sealing door on one side of the cleaning box, push the components onto the rubber layer through the guide plate and place them in the dust removal and drying chamber. The dust removal and drying unit performs dust removal and drying on the components in the dust removal and drying chamber. After dust removal is completed, the driving motor continues to operate, driving the conveyor belt, rubber layer, and the first rubber sheet to rotate. During the process of the first rubber sheet moving to the right, it pushes the bottom of the second rubber sheet, causing the second rubber sheet to flip with the movable column as the axis. When multiple first rubber sheets all enter the cleaning chamber, under the action of gravity, the second rubber sheet rotates back to its initial state, and the components enter the cleaning chamber. The cleaning unit cleans the components in the cleaning chamber. The components after dust removal enter the cleaning chamber, and the cleaning unit cleans the components in the cleaning chamber.

[0003] In the prior art including the above-mentioned patent, mostly enclosed boxes or semi-enclosed boxes are used, and the materials are dried after cleaning. Although this can ensure that the materials are dry after cleaning to prevent the influence of water vapor on them, the high temperature is carried out after cleaning, and it can only dry the materials. If high-temperature compressed air is used during cleaning or the temperature in the chamber is increased, a part of the dirt on the material surface will change its physical properties due to the high temperature, which may cause the dirt to adhere more tightly to the material or be blown away under the action of compressed air to expand the pollution area or remain on the inner wall of the chamber. This will not only affect the cleaning effect and efficiency but also pollute the inner wall of the device. Moreover, when there is more water vapor in the compressed air, the water vapor it carries may have an adverse effect on the material itself, which is particularly obvious on thinner plates. Summary of the Invention

[0004] The problems to be solved by the present invention are: enhancing the cleaning effect of compressed air and reducing the influence of water vapor on the material.

[0005] To solve the above technical problems, the technical solution of the present invention is: a material cleaning device for the production of mechanical and electrical parts, including a box body and a bracket. A clamping assembly is arranged at the lower end inside the box body.

[0006] Preferably, the clamping assembly includes a workbench. The upper end of the workbench is flush with the lower end of the inner wall of the box body. The workbench is hollow. An installation box is fixedly arranged inside the workbench. There are four installation boxes evenly distributed around the center of the workbench.

[0007] Preferably, the limiting tube penetrates through the front and rear ends of the installation box. A clamping jaw is slidably arranged on the outer surface of the limiting tube. The clamping jaw is slidably connected with the installation box. A corrugated pipe is fixedly arranged on the side of the clamping jaw away from the center of the workbench. The corrugated pipe is located outside the limiting tube. The other side of the corrugated pipe is fixedly connected with the installation box.

[0008] Preferably, the surface of the installation box connected with the corrugated pipe is provided with holes for ventilation. The holes on the installation box are located outside the limiting tube. An air duct is arranged inside the clamping jaw. There are two air ducts symmetrically arranged along the center line of the clamping jaw. The air ducts are communicated with the corrugated pipe. A spring is fixedly arranged on the side of the clamping jaw away from the corrugated pipe. The spring is located around the limiting tube. The other end of the spring is fixedly connected with the installation box.

[0009] Preferably, a connecting rod is fixedly arranged in the middle of the workbench. The connecting rod does not contact the installation box. Installation pipes are arranged around the connecting rod. The installation pipes are located at the lower end of the workbench. Storage boxes are arranged around the installation pipes. A plurality of stirring rods are fixedly arranged at the lower end of the storage box inside the connecting rod. A grid plate is arranged at the lower end of the stirring rods. The grid plate is fixedly connected with the storage box.

[0010] Preferably, a motor shaft is fixedly arranged at the lower end of the connecting rod. The motor shaft passes through the storage box, the grid plate and the bracket and is connected with the motor. Air supply pipes are fixedly arranged on both sides of the storage box. The air supply pipes are respectively located above and below the grid plate. Nozzles are fixedly arranged at the ends of the air supply pipes. The nozzles are located directly above the workbench. The nozzles are fixedly connected with the box body.

[0011] Preferably, a feed pipe is fixedly arranged on one side of the storage box. The feed pipe is located between two air supply pipes, above the grille plate, and the other end of the feed pipe is connected to a dry ice maker.

[0012] Preferably, the aggregate component includes a driving ring located outside the workbench. The driving ring is fixedly connected to the workbench. A straight chute is formed on the outer side of the driving ring, and there are four straight chutes in total. Impellers are arranged around the driving ring. An inclined slider is fixedly arranged on the outer side of the lower end of the impeller, and a straight slider is fixedly arranged on the inner side of the lower end of the impeller.

[0013] Preferably, the number of the straight sliders corresponds to that of the straight chutes. The straight sliders are arranged in the straight chutes. A limiting ring is arranged around the impeller. An inclined chute is formed on the inner surface of the limiting ring, and there are eight inclined chutes and eight inclined sliders.

[0014] Preferably, the limiting ring is fixedly connected to the box body. A material discharge hole is formed at the connection between the limiting ring and the box body. A filter screen is fixedly arranged outside the material discharge hole of the box body. The upper edge of the impeller is slidably connected to the inner wall of the filter screen.

[0015] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0016] (1) Through the arrangement of the clamping component, in areas with high humidity, the moisture in the compressed air can be reduced, avoiding adverse effects on materials due to excessive humidity. Moreover, using dry ice can not only reduce humidity but also lower the temperature of the compressed air, materials, and the chamber. Utilizing the characteristic that materials shrink at low temperatures, after shrinking, the adhesion degree of some dirt on their surface will be reduced accordingly. And under the action of low temperature, the dirt itself can also be embrittled. In this way, the dirt can be easily removed by high-pressure air. It is worth mentioning that the dry ice particles ejected with the air can act like abrasives to further remove stubborn dirt without damaging the material itself. The dry ice remaining on its surface will also leave no trace after vaporization, thereby improving the cleaning intensity and reducing the influence of moisture on it;

[0017] (2) Through the setting of the aggregate component, the wind force generated by the rotation of the impeller can throw the peeled dirt and dry ice particles towards the surrounding filter screens, and the centrifugal wind force generated can make some dry ice particles temporarily stay inside the chamber, continuously reducing the temperature inside the box. Moreover, after the cleaning stops, when the impeller returns to its position, it can also scrape off and collect the dirt and dry ice particles remaining on the filter screen. This can not only provide a guiding force for the peeled dirt during cleaning to prevent it from staying on the material again and causing secondary pollution, but also maintain the temperature inside the box to a certain extent, and prevent the dirt from splashing inside the chamber.

[0036] On one side of the storage box 210, a feeding pipe 216 is fixedly arranged. The feeding pipe 216 is located between the two air supply pipes 214. The feeding pipe 216 is located above the grid plate 212. The other end of the feeding pipe 216 is connected to a dry ice maker.

[0037] The aggregate component 4 includes a driving ring 401 located outside the workbench 201. The driving ring 401 is fixedly connected to the workbench 201. On the outside of the driving ring 401, straight sliding grooves 402 are provided. There are four straight sliding grooves 402 in total. Around the driving ring 401, an impeller 403 is arranged. On the outer side of the lower end of the impeller 403, an inclined sliding block 404 is fixedly arranged. On the inner side of the lower end of the impeller 403, a straight sliding block 405 is fixedly arranged.

[0038] The number of the straight sliding blocks 405 corresponds to that of the straight sliding grooves 402. The straight sliding blocks 405 are engaged with the straight sliding grooves 402. Around the impeller 403, a limiting ring 406 is arranged. On the inner surface of the limiting ring 406, inclined sliding grooves 407 are provided. There are eight inclined sliding grooves 407 and eight inclined sliding blocks 404. The inclined sliding blocks 404 are slidably connected to the inclined sliding grooves 407.

[0039] The limiting ring 406 is fixedly connected to the box body 1 , a feeding hole is provided at the connection between the limiting ring 406 and the box body 1 , a filter screen 408 is fixedly provided on the outside of the feeding hole of the box body 1 , and the upper edge of the impeller 403 is slidably connected to the inner wall of the filter screen 408 .

[0040] The working principle and use process of the present invention are as follows: before the cleaning work is started, the dry ice maker needs to be turned on first. After the dry ice maker is in operation, the dry ice will be transported to the storage box 210. Then the motor is started. The operation of the motor drives the workbench 201 and the stirring rod 211 to rotate slowly. As the stirring rod 211 rotates, the dry ice is evenly spread on the grid plate 212, and is crushed into particles under the coordinated action of the stirring rod 211 and the grid plate 212. After completing the above steps, the external air pump is started to pre-inflate the clamping assembly 2.

[0041] The gas enters from the air supply pipe 214 and first reaches the inside of the storage box 210. At this time, the gas is cooled down by the action of the dry ice particles, and a large amount of moisture in the air is also condensed in this process. Then, the air flows upward and downward respectively. The low-temperature air flowing upward enters the workbench 201 through the installation pipe 209, and under the guidance of the limit pipe 203, fills the workbench 201, and then enters the bellows 205. The gas in the bellows 205 increases, pushing the clamping claw 204 to move toward the center to clamp the plate to be cleaned. After that, the excess gas flows out from the air channel 206 and sprays toward the plate. In this way, the workbench 201 and the sprayed low-temperature air work together to achieve cooling of the plate, and the air flowing downward will carry the dry ice particles into the nozzle mechanism 215, and then spray toward the plate;

[0042] It should be noted that in the working state, the production speed of the dry ice maker, the flow rate of the air pump and the speed of the motor need to be increased. In the non-working state, the dry ice maker and the motor can be turned off, and the air pump can only operate at reduced power.

[0043] During the material cleaning process, when the motor drives the workbench 201 to rotate rapidly, the driving ring 401 drives the impeller 403 accordingly. When the impeller 403 rotates, it gradually rises under the interaction of the inclined sliding block 404 and the inclined sliding groove 407 until the inclined sliding block 404 leaves the range of the inclined sliding groove 407. The impeller 403 maintains the current position and starts working. The wind generated by the impeller 403 will throw the dirt and dry ice particles to the surrounding filter screen 408. After the cleaning work is completed, as the speed of the workbench 201 decreases, the inclined sliding block 404 enters the inclined sliding groove 407. At this time, the impeller 403 automatically moves down and resets under the action of its own gravity, and its outer edge can scrape off the dirt and dry ice particles remaining on the filter screen 408, causing them to fall into the inside of the bracket 3 for cleaning during maintenance.

[0044] The above embodiments are only exemplary embodiments of the present invention and are not used to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions within the essence and protection scope of the present invention, and such modifications or equivalent substitutions should also be regarded as falling within the protection scope of the present invention.
