Description

Technical Field

[0001] This utility model relates to the technical field of waste acid treatment equipment, specifically to a waste acid evaporation and crystallization device. Background Technology

[0002] Evaporation crystallization is mainly used for the recovery and treatment of waste acid liquids containing volatile acids such as hydrochloric acid, hydrofluoric acid, and nitric acid. The working principle of evaporation crystallization is based on the volatile nature of hydrochloric acid, hydrofluoric acid, and nitric acid. By heating, acidic gas is generated through evaporation and then condensed to form recovered acid. The concentrated liquid is then treated differently depending on the type of waste acid liquid. For hydrochloric acid waste liquid, byproducts such as ferrous chloride, aluminum chloride, and copper chloride can be obtained. When evaporating and crystallizing waste acid, a waste acid evaporation crystallization device is required.

[0003] Existing crystallization equipment cannot effectively filter acidic gases during the evaporation of waste acid. This results in the direct release of acidic gases into the environment, causing pollution and harming the health of workers who inhale large amounts of these gases. Furthermore, during the filtration process, crystals tend to accumulate on one part of the interceptor plate, reducing its interception efficiency and effectiveness, thus diminishing the overall practicality of the device.

[0004] Compared with Chinese Patent Publication No. CN219314627U, this utility model discloses a waste acid evaporation crystallization device. The separation module is used to separate the crystallizer from the concentrate. It includes a shell set on one side of the tank, a connecting pipe connecting the bottom of the tank and the top of the shell, an electric valve installed on the connecting pipe, a support leg fixed to the bottom of the shell, a pump installed on the support leg and connected to the bottom of the shell, guide rails symmetrically fixed on the inner wall of the shell, a collection frame movably set in the inner cavity of the shell, a filter screen installed on the inner wall of the collection frame, and an inlet pipe connecting the pump and the inlet pipe. The shell forms a sealed space for installing other components. One end of the connecting pipe is connected to the bottom of the tank and the other end is connected to the top of the shell, which is used to send the concentrate mixed and crystallized in the inner cavity of the tank into the inner cavity of the shell. The electric valve is used to control the opening and closing of the connecting pipe. This waste acid evaporation crystallization device has the advantages of avoiding crystallization blockage and being highly practical.

[0005] The above-mentioned solution can effectively crystallize waste acid, but it still cannot effectively filter acidic gases. Furthermore, it cannot effectively utilize the full performance of the filter screen and fails to solve the problems mentioned in the background section.

[0006] Therefore, those skilled in the art have provided a waste acid evaporation and crystallization device to solve the problems mentioned in the background art. Utility Model Content

This component effectively stirs the waste acid, improving crystallization efficiency, and also effectively filters the crystals. The crystals on the inner wall of the evaporation cylinder are scraped off. After the waste acid has evaporated, the solenoid valve opens, and the waste acid, carrying the crystals, is transferred through the discharge pipe to the inside of the discharge head, and then discharged into the storage tank. At the same time as the solenoid valve opens, the regulating component also starts to operate synchronously.

After the waste acid passes through the interception component, the liquid pump starts to operate.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1 - Figure 7 As shown, this embodiment provides a waste acid evaporation and crystallization device, including a base 1, and further comprising:

[0032] Storage box 2 is fixedly connected to the upper surface of base 1. An electromagnetic heating plate 16 is fixedly connected to the upper surface of storage box 2.

The bottom of fixing frame 4 is fixedly connected to the upper surface of base 1. A discharge pipe 6 is connected to the outside of evaporation cylinder 3 through electromagnetic valve 5. The discharge end of discharge pipe 6 extends into the interior of storage box 2 and is connected to discharge head 17.

[0033] The scraping and stirring components are located on the upper surface of the evaporator cylinder 3;

[0034] Adjustment components are respectively installed on the front and rear inner walls of storage box 2;

[0035] The interception component is located inside storage box 2;

[0036] A liquid pump 11 is fixedly connected to the upper surface of the base 1. The liquid inlet of the liquid pump 11 is connected to the bottom of the storage tank 2 through a pipe.

A support frame 7 is fixedly connected to the outside of the evaporation cylinder 3.

[0037] The filter assembly is disposed on the upper surface of the support frame 7.

[0038] The working principle is as follows: When waste acid needs to be evaporated and crystallized, simply add the waste acid into the evaporation cylinder 3. At this time, the electromagnetic heating plate 16 starts operating, effectively heating and evaporating the waste acid. The evaporated acidic gas is then transmitted to the filter assembly through the exhaust pipe 9. The filter assembly effectively filters the acidic gas, preventing it from harming the environment and the health of workers. As the waste acid evaporates, its concentration increases, forming crystals. At this point, the scraping and stirring assembly starts operating. This assembly effectively stirs the waste acid, improving its crystallization efficiency, and also effectively scrapes away the crystals on the inner wall of the evaporation cylinder 3. When the waste acid evaporates... After completion, solenoid valve 5 opens, and the waste acid, carrying crystals, is transferred through discharge pipe 6 to the inside of discharge head 17, and then discharged through discharge head 17 to the inside of storage tank 2. At the same time as solenoid valve 5 opens, the regulating component also starts to operate synchronously. At this time, the regulating component will drive the discharge head 17 to move synchronously, so that the waste liquid and crystals can fall evenly and comprehensively to the outside of the interception component, thereby effectively improving the interception effect of the interception component, and allowing the crystals to adhere to the outside of the interception component for easy collection by the staff. After the waste acid passes through the interception component, the liquid pump 11 starts to operate. At this time, the liquid pump 11 will transfer the waste acid inside storage tank 2 to the inside of evaporation cylinder 3 for evaporation and crystallization treatment, effectively improving the crystallization effect and efficiency of waste acid, and improving the overall practicality of the device.

[0039] To effectively scrape away crystals on the inner wall of the evaporator 3, the scraping and stirring assembly includes a first motor 12 fixedly connected to the upper surface of the evaporator 3. The output shaft of the first motor 12 is fixedly connected to a rotating rod 13 via a coupling. Multiple stirring frames 14 are fixedly connected to the outside of the rotating rod 13, and scrapers 15 are fixedly connected to the outside of each stirring frame 14. When the waste acid is evaporated and crystallized, the first motor 12 will also start running synchronously. At this time, the first motor 12 will drive the rotating rod 13 to rotate synchronously, and the rotating rod 13 will drive the stirring frames 14 and scrapers 15 to rotate synchronously. At this time, the stirring frames 14 can effectively stir the waste acid, thereby effectively improving the crystallization efficiency of the waste acid, while the scrapers 15 can effectively scrape away the crystals adhering to the inner wall of the evaporator 3.

[0040] Considering the need to improve the interception effect and efficiency of the interception plate 25 during the interception and filtration process of crystals, the adjustment assembly includes adjustment plates 18 respectively disposed on the inner walls of the front and rear of the storage tank 2.

A threaded block 21 is threadedly connected to the outside of the threaded rod 20. Guide grooves for the slider 23 and threaded block 21 to move are respectively opened on opposite sides of the two adjustment plates 18. A movable plate is fixedly connected between the slider 23 and threaded block 21. 24. The interior of the movable plate 24 has a through-hole for installing the discharge head 17. When the solenoid valve 5 is opened, the second motor 19 will also start running synchronously. At this time, the second motor 19 will drive the threaded rod 20 to rotate synchronously, and the threaded block 21 will move synchronously outside the threaded rod 20, driving the movable plate 24 to move synchronously. The movable plate 24 will then drive the slider 23 to move synchronously outside the slider 22. The movable plate 24 will also drive the discharge head 17 to move synchronously. At this time, the position of the discharge head 17 can be adjusted and moved, thereby avoiding the accumulation of waste acid and solid waste in one part of the interceptor plate 25, effectively improving the filtration effect and efficiency of the interceptor plate 25 for crystallization, and giving full play to the performance of the interceptor plate 25.

The pull ring will drive the insertion rod 36 to move synchronously. The insertion rod 36 will then drive the contact plate 37 to move synchronously. During the movement of the contact plate 37, it will compress the return spring 38. At this time, the interceptor plate 25 is inserted into the inside of the two guide frames 26. The interceptor plate 25 will drive the outer plate 27 to move synchronously. The outer plate 27 will then drive the side plate 28 and the L-shaped plate 29 to move synchronously. The L-shaped plate 29 will then... The insert block 30 moves synchronously. When the insert block 30 is inserted into the inside of the fixed frame 34, the pull ring is released.

Each mounting frame 39 has a feed opening on its upper surface. The guide groove of the mounting block 33 is connected to the outside of the filter box 8 by a vent pipe 10. During the evaporation and crystallization process of waste acid, a large amount of acidic gas will be generated. At this time, the acidic gas will be transmitted to the inside of the filter box 8 through the exhaust pipe 9. When the acidic gas enters the inside of the filter box 8, the activated carbon honeycomb filter plate 31 can effectively filter the acidic gas. The filtered gas is then discharged through the vent pipe 10.

During the movement of the contact plate 42, the contact spring 43 will be squeezed. Then, the mounting block 33 is inserted into the inside of the mounting frame 39, and the pull plate is released. At this time, the contact spring 43 returns to its original position, driving the contact plate 42 and the fixed rod 41 to move synchronously.
