Description

Technical Field

[0001] The utility model relates to the technical field of particle material processing, in particular to a cleaning device for particle material processing. Background Art

[0002] Artificially cultivated granular materials need to go through multiple rounds of growth to reach a thickness that can be grinded. Before each round of growth, the growth layer of the granular materials and the surrounding polycrystals need to be removed by laser processing to facilitate subsequent growth. However, graphite and residual carbon powder are usually produced during laser cutting and grinding. These impurities will directly stick to the surface of the polished granular materials, and the granular materials need to be cleaned. Currently, the common way to deal with these impurities is acid washing (cleaning with a cleaning solution prepared in a certain proportion of concentrated sulfuric acid and concentrated nitric acid), but the waste acid after use pollutes the environment more greatly, and concentrated acid is also dangerous to a certain extent. There are safety hazards in the cleaning process of granular materials.

[0003] Based on this, the prior art, such as the utility model patent with authorization announcement number CN217165473U, discloses a multi-layer cleaning device for artificial diamonds, which specifically discloses a cleaning box, wherein the top inner wall and the inner side wall of the cleaning box are respectively equipped with a dispersed nozzle and a high-pressure jet head. After the artificial diamond raw material enters the cleaning box from the drop port, it falls between the filter box and the filter screen in the material lifting control structure in the cleaning box. During the lifting process of the material lifting control structure in the cleaning box, the diamond raw material is cleaned by the dispersed nozzle and the high-pressure jet head. Finally, a sufficient amount of water is added to the cleaning box so that the water covers the artificial diamond, and then the ultrasonic generator is turned on to ultrasonically clean the diamond raw material between the filter box and the filter screen.

[0004] Although the above-mentioned prior art can realize high-pressure washing and ultrasonic washing of artificial diamond raw materials, a better cleaning effect of impurities is achieved through high-pressure jet and ultrasonic two-layer cleaning, thereby replacing traditional acid washing. However, during the cleaning process, the height of the drive motor is adjusted by the electric lifting rod so that the drive motor drives the filter box to flip for multi-directional cleaning. After the high-pressure jet cleaning is completed, the height of the filter box needs to be specially adjusted for ultrasonic washing. The switching between the jet washing and ultrasonic washing processes is more troublesome, and the structure inside the cleaning box is complex, which increases the difficulty of manufacturing; at the same time, when it is washed by water spraying through the nozzle, the water flow will also be sprayed on the drive motor, the electric lifting rod and other electric mechanisms. In particular, when ultrasonic cleaning is performed, sufficient water needs to be added to the cleaning box, so that the drive motor is soaked in water for a long time, which is very likely to cause damage to the drive motor and other electric structures or even scrap, especially when the drive motor needs to be replaced, resulting in higher costs. Not only does the cleaning device often fail to be used, which affects the production of artificial diamonds, but also the maintenance cost is too high due to the significantly increased frequency of maintenance, and the overall cost invested is too high. Utility Model Content

[0005] The utility model aims to provide a cleaning device for granular material processing, so as to solve the problems in the prior art that when cleaning granular material impurities by water jetting and ultrasonic cleaning, the process switching between jet cleaning and ultrasonic cleaning is troublesome, and the manufacturing and maintenance costs of the cleaning box are high.

[0006] To achieve the above-mentioned purpose, the technical solution of the cleaning device for processing granular materials provided by the utility model is: it includes a cleaning box, the inner cavity of the cleaning box is divided into a flushing chamber and an ultrasonic chamber arranged upper and lower, the flushing chamber is provided with a high-temperature and high-pressure injection mechanism and a filter support plate for supporting the granular materials, the filter support plate is horizontally inserted in the cleaning box, and the granular materials can be dropped into the ultrasonic chamber by pulling out the filter support plate.

[0007] As a further improvement, a partition plate is horizontally inserted in the cleaning box to separate the flushing chamber and the ultrasonic chamber. Pulling out the partition plate and the filter support plate can allow the granular material to fall into the ultrasonic chamber.

[0008] As a further improvement, a limit plate is inserted in the cleaning box, and the limit plate is arranged in a vertical fit with the filter support plate. The limit plate is provided with holes for placing the granular material in the holes and being supported by the filter support plate.

[0009] As a further improvement, the holes are evenly and densely distributed on the limit plate.

[0010] As a further improvement, the holes are arranged in a matrix.

[0011] As a further improvement, the high-temperature and high-pressure injection mechanism includes a nozzle disposed above the limiting plate, and the nozzle is arranged corresponding to the hole position.

[0012] As a further improvement, a carrier plate is provided in the ultrasonic chamber for supporting the granular material falling into the flushing chamber, and filtering holes are provided on the carrier plate.

[0013] As a further improvement, the loading plate can be detachably mounted on the cleaning box and can be taken out as a whole.

[0014] As a further improvement, the carrier plate is installed close to the bottom wall of the ultrasonic chamber.

[0015] As a further improvement, the carrier plate is inserted into the cleaning box.

[0016] The beneficial effect is: the utility model provides a cleaning device for processing granular materials which is improved on the basis of the multi-layer cleaning device of artificial diamond in the prior art. When cleaning the granular materials, the granular materials are first placed on the filter support plate in the flushing chamber, and the granular materials are flushed by a high-temperature and high-pressure jet mechanism. After the granular materials are flushed with high pressure, the operator can directly pull out the filter support plate, and the granular materials on the filter support plate will fall into the ultrasonic chamber for ultrasonic cleaning.

[0017] The cleaning device for processing granular materials provided by the utility model only needs to pull out the filter support plate during cleaning work to allow the granular materials to fall directly from the flushing chamber into the ultrasonic chamber, so as to enter the ultrasonic cleaning process from the jet flushing process. The switching between the two cleaning processes is convenient and rapid. At the same time, the cleaning box has a simple structure, is easy to manufacture, and is easy to operate and not easy to damage. It can be used for a long time in cleaning work, and the overall processing, manufacturing and maintenance costs invested are low, which is conducive to promotion. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0022] Artificially cultivated granular materials need to be cleaned during and after their growth. To ensure the cleaning effect, pickling is generally performed using a cleaning solution prepared in a certain proportion of concentrated sulfuric acid and concentrated nitric acid to ensure the cleaning effect. However, the waste liquid generated by pickling not only pollutes the environment, but also has certain dangers during the cleaning process. Based on this, the prior art cited in the background technology uses a multi-layer cleaning device such as clean water spraying and ultrasonic cleaning to replace traditional pickling, which not only has a better cleaning effect on impurities on the granular materials, but also avoids safety hazards and environmental pollution hazards during the cleaning process. However, an electric lifting rod, a drive motor, etc. are provided in the cleaning box, which requires wiring and other operations to realize electric control, resulting in a complex structure of the cleaning box. The most important thing is that the processing difficulty of the cleaning box is relatively high, resulting in excessive production costs and difficulty in widespread promotion. The utility model provides a cleaning device for processing granular materials to solve the problems existing in the above-mentioned prior art, and the cleaning device for processing granular materials provided by the utility model is particularly suitable for cleaning diamonds.

[0023] The overall design concept of the cleaning device for particle material processing provided by the utility model is:

[0024] like Figure 1-Figure 2 As shown, a cleaning device for processing granular materials comprises a cleaning box 1, the inner cavity of the cleaning box 1 is divided into a flushing chamber and an ultrasonic chamber 8 arranged upper and lower, a high-temperature and high-pressure jet mechanism and a filter support plate 4 are arranged in the flushing chamber, the filter support plate 4 is horizontally inserted in the cleaning box 1, and the granular materials are supported by the filter support plate 4 for cleaning, and a liquid inlet pipe is externally connected to the cleaning box for supplying water or cleaning liquid to realize jet flushing and ultrasonic cleaning.

[0025] When cleaning the granular material, the granular material is first placed on the filter support plate 4, and the granular material is sprayed and washed by the high-temperature and high-pressure spray mechanism. The high-temperature and high-pressure spray washing can reliably ensure the cleaning effect of the granular material. After the granular material is sprayed and washed, the operator can directly pull out the filter support plate 4 so that the granular material falls into the ultrasonic chamber 8 for ultrasonic cleaning. The water in the ultrasonic chamber 8 generates a cavitation effect, so that the water can be cleaned wherever it reaches, so as to clean the edges and corners of the granular material, thereby achieving all-round cleaning of the granular material; and there is no need to set up an additional stirring structure, which not only reduces the cleaning cost, but also avoids damage to the granular material.

[0026] The cleaning device for processing granular materials provided by the utility model only needs to pull out the filter support plate 4 during the cleaning work so that the granular materials can be directly transferred from the jet flushing process to the ultrasonic cleaning process. No other complicated structures need to be arranged in the cleaning box 1 so as to realize the rapid switching of the two cleaning processes of high-temperature and high-pressure jet flushing and ultrasonic cleaning. The structure is simple, the manufacturing process is simple, the required manufacturing time is short, the manufacturing cost is significantly reduced, and the operation process is simple, the granular materials can be used normally for a long time, the maintenance cost is low, and it is conducive to the popularization and use in actual work.

[0027] Based on the overall introduction of the present invention above, a more specific embodiment is provided below on the basis of the overall introduction:

[0028] like Figure 1-Figure 2 As shown, a partition plate 6 is also horizontally inserted in the cleaning box 1, and the partition plate 6 divides the inner cavity of the cleaning box 1 into an independent flushing chamber and an ultrasonic chamber 8, and a drainage structure is provided on the side wall of the flushing chamber, so that during the high-temperature and high-pressure jet flushing, waste water carrying impurities is directly discharged from the drainage structure and will not flow into the ultrasonic chamber 8, thereby ensuring the cleanliness of the ultrasonic chamber 8, and while the flushing process is being carried out in the flushing chamber, water or cleaning liquid can be supplied to the ultrasonic chamber 8 for cleaning, so that after the jet flushing is completed, the filter support plate 4 and the partition plate 6 can be directly pulled out to allow the granular material to fall into the ultrasonic chamber 8, thereby realizing the rapid connection between the jet flushing process and the ultrasonic cleaning process, and improving the work efficiency of the granular material cleaning operation.

[0029] A limit plate 3 is also inserted in the cleaning box 1. The limit plate 3 is arranged in a vertically contacting relationship with the filter support plate 4. A hole is provided through the limit plate 3. The granules are placed in the hole, and the filter support plate 4 supports the granules from below. During the process of the high-pressure water flow in the high-temperature and high-pressure injection mechanism spraying and flushing the granules, the granules can be restricted and constrained in the hole on the limit plate 3, thereby preventing the granules from being flushed to the edge of the filter support plate 4 during the flushing of the high-pressure water flow and affecting the spraying and flushing effect.

[0030] After the spray flushing is completed, the operator only needs to pull out the filter support plate 4 from the cleaning box 1. At this time, the bottom of the granular material in the hole of the limiting plate 3 is no longer supported, and the granular material will fall to the next process. The use of the filter support plate 4 and the limiting plate 3 can prevent the granular material from being brought to the side wall of the cleaning box 1 when only the filter support plate 4 is set, and in the process of pulling out the filter support plate 4, the granular material is continuously accumulated on the side wall of the filter support plate 4 extraction opening of the cleaning box 1, and the granular material squeezes and bumps against each other, causing scratches and other losses.

[0031] In order to prevent the particles from being stacked on the filter support plate 4 and affecting the jet flushing effect of the high temperature and high pressure mechanism, the holes are evenly and densely arranged on the limit plate 3, and each hole can accommodate a single particle. At this time, it can not only prevent the particles from being stacked on the filter support plate 4 to ensure that each particle is jet cleaned, the cleaning effect of the particles is reliably guaranteed, and it can also avoid that all the particles are flushed to one place during the high-pressure jet flushing process, resulting in scratches caused by collisions between the particles. Specifically, the holes are arranged in a matrix to facilitate the placement of the particles. In other embodiments, especially when the limit plate is a circular plate, the holes are arranged in a ring array on the limit plate.

[0032] The inner wall of the cleaning box 1 is provided with a transverse insertion groove for inserting the partition plate 6 and the filter support plate 4. The two ends of the partition plate 6 and the filter support plate 4 are respectively inserted in the corresponding transverse insertion grooves. During the actual production and use of the cleaning box 1, the installation position of the partition plate 6 can be changed by changing the layout position of the transverse insertion groove in the up and down directions, thereby changing the size of the flushing chamber and the ultrasonic chamber 8 formed by the partition plate 6 in the cleaning box 1, so as to make timely adjustments according to the actual needs in the particle cleaning process. The disassembly and assembly are simple, the compatibility is good, and it is easy to promote and apply.

[0033] By opening two parallel transverse insertion grooves on opposite sides of the cleaning box 1, the partition plate 6 can be pulled out and installed. Similarly, by opening two more transverse insertion grooves on the inner wall of the cleaning box 1, the filter support plate 4 can be installed. Transverse insertion grooves can also be set on three sides of the inner wall of the cleaning box 1 to ensure the insertion stability of the partition plate 6 and the filter support plate 4.

[0034] In order to further ensure the installation reliability of the partition plate 6 and the filter support plate 4, the transverse insertion groove is a dovetail groove. At this time, dovetail-shaped protrusions that cooperate with the dovetail groove are provided on both sides of the partition plate 6 and the filter support plate 4. Through the cooperation of the dovetail groove and the dovetail-shaped protrusion, the stability of the insertion can be improved on the basis of realizing the insertion of the partition plate 6, the filter support plate 4 and the cleaning box 1, and the phenomenon of shaking of the filter support plate 4 and the partition plate 6 will not occur, and the disassembly and assembly are also convenient. Of course, in other embodiments, the transverse insertion groove can also be a rectangular groove directly opened on the inner wall of the cleaning box 1, and the partition plate 6 and the filter support plate 4 can be directly inserted without other structures at both ends.

[0035] The washing chamber and the ultrasonic chamber 8 separated by the partition plate 6 on the cleaning box 1 are both provided with drainage structures, so as to drain water during the jet washing and ultrasonic cleaning processes respectively, so that the impurities washed away are carried by the water flow and discharged. Specifically, the drainage structure in the washing chamber is arranged at a position close to the partition plate 6. At this time, the chamber between the filter support plate 4 and the partition plate 6 forms a drainage chamber 5 in the washing chamber. The water flow during the jet washing process carries impurities such as graphite and residual carbon powder, which seep out from the filter support plate 4 and are discharged by the drainage structure. Preferably, in order to improve the manufacturing efficiency of the cleaning box 1, the drainage structure is a first drainage hole 7 directly opened on the side wall of the washing chamber, and a second drainage hole 10 directly opened on the side wall of the ultrasonic chamber 8. Or in other embodiments, the drainage structure is a drainage pipe externally connected to the washing chamber and the ultrasonic chamber, so as to facilitate the discharge of wastewater carrying impurities to a designated location.

[0036] Based on the overall introduction of the present invention above, a more specific embodiment is provided below on the basis of the overall introduction:

[0037] This embodiment focuses on the detailed description of the ultrasonic chamber.

[0038] like Figure 1-Figure 2 As shown, the cleaning box 1 is provided with an ultrasonic generator at the ultrasonic chamber 8, so as to ultrasonically clean the granular material in the ultrasonic chamber 8. Preferably, the ultrasonic generator is arranged at the bottom of the cleaning box to ensure the fluctuation range of the ultrasonic wave, thereby improving the effect of ultrasonic cleaning.

[0039] In order to further improve the cleaning effect in the ultrasonic chamber 8, a carrier plate 9 is provided in the ultrasonic chamber 8. After the filter support plate 4 and the partition plate 6 are pulled out, the granular material in the hole of the limit plate 3 falls on the carrier plate 9. The carrier plate 9 is provided with a filter hole. During the ultrasonic cleaning process, water can enter through the filter hole to clean the bottom of the granular material, further achieving all-round cleaning of the granular material. Specifically, the carrier plate 9 is arranged close to the bottom wall of the ultrasonic chamber 8, which can not only be relatively closer to the ultrasonic generator, but also can make the cleaning liquid in the ultrasonic chamber 8 not too much, that is, the cleaning liquid can cover the granular material on the carrier plate 9, so that the granular material on the carrier plate 9 can be cleaned on both the upper and lower sides.

[0040] In order to facilitate the operator to quickly remove the granular material on the carrier plate 9 after the ultrasonic cleaning work is completed, the carrier plate 9 is detachably installed on the cleaning box 1 and can be removed as a whole. Preferably, the carrier plate 9 is inserted into the cleaning box 1, and the insertion and installation method of the carrier plate 9 is the same as the insertion setting of the above-mentioned partition plate 6 and the filter support plate 4, which will not be repeated here. Furthermore, the carrier plate is drawer-shaped, which not only has a better supporting effect for the granular material, but also can facilitate the operator to quickly pull the carrier plate out of the cleaning box to take away the cleaned granular material; or in other embodiments, an opening equipped with a cover plate can be provided on the side wall of the cleaning box, and the opening corresponds to the setting of the carrier plate. After the cleaning of the granular material is completed, the operator can take out the granular material on the carrier plate through the opening.

[0041] Based on the overall introduction of the present invention above, a more specific embodiment is provided below on the basis of the overall introduction:

[0042] This embodiment focuses on the high-temperature and high-pressure injection mechanism and provides a detailed description.

[0043] like Figure 1-Figure 2 As shown, the high temperature and high pressure spray mechanism includes a spray head 2 arranged on the inner wall of the top plate of the cleaning box 1, and the spray head 2 is arranged corresponding to the hole position. At this time, the upper part of each single particle material has a separate spray head 2, which can reliably ensure the spraying and flushing effect of each particle material. In other embodiments, a single spray head can also correspond to two, three or four holes at the same time. In this case, the investment cost is relatively low, and the cleaning of the particles in the holes can also be achieved.

[0044] The nozzle 2 of the high-temperature and high-pressure spraying mechanism can also be a row of nozzles 2 arranged along the width direction or the length direction of the cleaning box 1. In this case, a corresponding slide is provided inside the cleaning box 1 for the nozzle 2 to slide, so that the spray flushing of the granular material is achieved during the sliding process of the row of nozzles 2.

[0045] It should be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0046] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
