Description

Technical Field

[0001] This utility model relates to the field of diamond pickling technology, specifically to a device for a synthetic diamond pickling tank. Background Technology

[0002] After the production of synthetic diamonds, impurities need to be removed by acid washing. Existing acid washing tank equipment has obvious technical shortcomings in practical applications: First, the acid solution is mostly left to stand naturally or simply stirred, resulting in uneven contact with diamond particles. Some particles are easily encapsulated, leading to incomplete acid washing and low efficiency. Second, the residual heat generated by the acid washing reaction is difficult to control precisely, causing fluctuations in the acid solution temperature, which affects the acid washing reaction rate and the impurity removal effect. Third, when the acid mist escapes, it is easy to carry tiny diamond particles, which not only causes raw material loss but also increases the difficulty of subsequent acid mist treatment. Utility Model Content

[0003] In view of the problems existing in the above-mentioned artificial diamond pickling tank device, this utility model is proposed.

[0004] Therefore, the purpose of this utility model is to provide a synthetic diamond pickling tank device, which solves the problem that the acid solution is mostly left to stand naturally or simply stirred, resulting in uneven contact with diamond particles and some particles being easily coated, leading to incomplete pickling.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A synthetic diamond pickling tank device includes a pickling tank body. A guide plate and hanging ears are fixedly provided on the inner side wall of the pickling tank body. A porous support basket is disposed inside the pickling tank body. Hanging rings are fixedly provided on both side walls of the porous support basket. The porous support basket is suspended inside the pickling tank body by the cooperation of the hanging rings and hanging ears. A heat exchange chamber is wrapped around the outer side wall of the pickling tank body. A heat-conducting layer is sandwiched between the heat exchange chamber and the outer side wall of the pickling tank body. A heat exchange medium outlet is provided at the bottom of the heat exchange chamber, and a heat exchange medium inlet is provided at the top of the heat exchange chamber. A sealing cover is closed on the top of the pickling tank body. An acid mist collection channel is opened in the middle of the sealing cover. Multiple layers of intercepting mesh are fixed inside the acid mist collection channel. An acid mist treatment component is sealed and connected to the outlet end of the acid mist collection channel.

[0006] Preferably, a circulation pipe is fixedly provided at the bottom of the pickling tank body, a pump body and a valve body are fixedly provided on the wall of the circulation pipe, one end of the circulation pipe is fixedly connected to a sealing cap, and a temperature sensor is embedded in the side wall of the pickling tank body.

[0007] Preferably, the acid mist treatment assembly includes an acid mist absorption tower and a fan.

[0009] Furthermore, a control panel is fixedly installed on the outer wall of the acid mist absorption tower.

[0010] Preferably, solenoid valves are fixedly installed on the outer walls of both the heat exchange medium outlet and the heat exchange medium inlet.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. In this utility model, the guide plate, circulation pipe and pump body are combined with the through hole design of the suspended porous bearing basket to make the acid solution form a directional circulation flow, which greatly improves the uniformity of contact between the acid solution and diamond particles, avoids the particles being wrapped by the acid solution and thus avoids incomplete pickling, effectively improving pickling efficiency and impurity removal effect.

[0012] 2. In this utility model, the heat exchange chamber on the outer wall of the pickling tank body is combined with a heat-conducting layer. With the synergistic effect of the temperature sensor and the solenoid valve, the residual heat generated by the pickling reaction can be precisely controlled, the acid temperature can be stabilized, the influence of temperature fluctuation on the pickling reaction rate can be avoided, and the consistency of the pickling quality of artificial diamond can be guaranteed.

[0013] 3. In this utility model, the sealing cover, acid mist collection channel, multi-layer interception net, and acid mist treatment components form a closed-loop design.

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model discloses a device for acid pickling tank for artificial diamond.

[0019] This utility model provides, for example Figure 1-3The illustrated synthetic diamond pickling tank device includes a pickling tank body 1. A guide plate 2 is fixedly installed on the inner wall of the pickling tank body 1. Hanging ears 3 are also fixedly installed on the inner wall of the pickling tank body 1. A porous support basket 4 is disposed inside the pickling tank body 1. Hanging rings 5 ​​are fixedly installed on both side walls of the porous support basket 4. The porous support basket 4 is suspended inside the pickling tank body 1 by the cooperation of the hanging rings 5 ​​and the hanging ears 3. A heat exchange chamber 6 is wrapped around the outer wall of the pickling tank body 1. A heat-conducting layer 7 is sandwiched between the heat exchange chamber 6 and the outer wall of the pickling tank body 1. A heat exchange medium outlet 8 is provided at the bottom of the heat exchange chamber 6, and a heat exchange medium inlet 9 is provided at the top of the heat exchange chamber 6. A sealing cover 10 is fitted over the top of the pickling tank body 1. An acid mist collection channel 11 is provided in the middle. Multiple layers of intercepting mesh 12 are fixed inside the acid mist collection channel 11. An acid mist treatment component is sealed to the outlet end of the acid mist collection channel 11. First, the artificial diamond particles to be acid-washed are placed into a porous support basket 4. The porous support basket 4 is suspended inside the acid washing tank body 1 by the engagement of the hanging rings 5 ​​on both sides of the basket with the hanging ears 3 fixed to the inner wall of the basket. The pump body 14 on the wall of the circulation pipe 13 is started, and the valve body 15 is opened. The acid in the acid washing tank body 1 is transported to the sealing cover 10 through the circulation pipe 13. Then, the acid flows to the guide plate 2 fixed to the inner wall of the acid washing tank body 1. Guided by the guide plate 2, the acid is sprayed directionally onto the surface of the diamond particles in the porous support basket 4. Simultaneously, the acid can pass through… Through the perforations on the sidewalls and bottom of the porous bearing basket 4, the acid solution achieves all-round contact with the diamond particles. After one round of contact, the acid solution flows back to the bottom of the pickling tank body 1, and is then transported again through the circulation pipe 13 and pump body 14, forming a circulating flow of acid solution to continuously contact the diamond particles to remove impurities. During the pickling reaction, the temperature sensor 16 embedded in the sidewall of the pickling tank body 1 detects the acid solution temperature in real time and transmits the temperature signal to the relevant control unit. When the acid solution temperature is too high, the solenoid valve 22 on the outer wall of the heat exchange medium outlet 8 and the heat exchange medium inlet 9 is controlled to increase the opening of the heat exchange medium inlet 9 and adjust the opening of the heat exchange medium outlet 8, so that the heat exchange medium enters the heat exchange cavity 6 wrapped by the outer wall of the pickling tank body 1. The heat-conducting layer 7 sandwiched between the side walls quickly transfers the residual heat of the acid solution in the pickling tank body 1 to the heat exchange medium. The heat-exchanged medium is discharged from the heat exchange medium outlet 8, thus cooling the acid solution. If the temperature is too low, the flow rate of the heat exchange medium is reduced by adjusting the opening of the solenoid valve 22 to maintain the acid solution within a suitable reaction temperature range and ensure the stable progress of the pickling reaction. The acid mist generated during the pickling process is not easily dispersed to the outside due to the sealing cover 10 covering the top of the pickling tank body 1. Instead, it flows into the acid mist collection channel 11 opened in the middle of the sealing cover 10. When the acid mist passes through the multi-layer interception net 12 fixed inside the acid mist collection channel 11, the interception net 12 will trap the tiny diamond particles entrained in the acid mist to avoid raw material loss. Then, the fan 18 in the acid mist treatment component is started.The fan 18 draws the intercepted acid mist into the acid mist collection channel 11 and transports it into the acid mist absorption tower 17. At this time, the spray tank 19 at the top of the acid mist absorption tower 17 sprays acid mist absorption liquid through the spray nozzle 20 at the bottom. The absorption liquid comes into full contact with the acid mist, neutralizing and purifying it to meet environmental emission requirements. Throughout the process, the operating status of components such as the pump body 14, valve body 15, solenoid valve 22, and fan 18 can be adjusted via the control panel 21 on the outer wall of the acid mist absorption tower 17 to ensure stable operation of the device.

[0020] To facilitate the circulation of acid, such as Figure 1 As shown, a circulation pipe 13 is fixedly provided at the bottom of the pickling tank body 1. A pump body 14 and a valve body 15 are fixedly provided on the wall of the circulation pipe 13. One end of the circulation pipe 13 is fixedly connected to a sealing cap 10. A temperature sensor 16 is embedded in the side wall of the pickling tank body 1.

[0021] To facilitate the absorption of acid mist, such as Figure 1 As shown, the acid mist treatment assembly includes an acid mist absorption tower 17 and a fan 18.

[0022] To achieve better absorption of acid mist, such as Figure 3 As shown, a spray tank 19 is fixedly provided on the top of the acid mist absorption tower 17, and a spray nozzle 20 is fixedly provided on the bottom of the spray tank 19.

[0023] Finally, for ease of operation, such as Figure 1 As shown, a control panel 21 is fixedly installed on the outer wall of the acid mist absorption tower 17, and solenoid valves 22 are fixedly installed on the outer walls of the heat exchange medium outlet 8 and the heat exchange medium inlet 9.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
