Description

Technical Field

[0001] The utility model relates to the technical field of industrial waste salt treatment, in particular to an industrial waste salt purification device. Background Art

[0002] Industrial waste salt refers to waste salt containing organic matter and other toxic and harmful substances and water generated in the industrial production process; it mainly comes from industries such as petrochemicals, pesticides, medicines and fine chemicals. Recycling and purifying industrial waste salt can not only eliminate the harm of waste salt to the environment, but also recycle and fully utilize the waste salt to achieve a circular economy. At present, the commonly used methods for treating waste salt containing organic matter include dissolution and refining followed by secondary concentration and crystallization treatment, direct thermal incineration, high-temperature carbonization and other methods. In conventional secondary concentration and crystallization treatment operations, the treatment of industrial high-salt wastewater containing industrial waste salt is generally carried out through an industrial high-salt wastewater separation and purification device to automatically precipitate the salt in the concentrated brine and separate it for purification.

[0003] The Chinese invention patent with publication number CN115286160B discloses a method for separating and purifying industrial high-salt wastewater, which relates to the technical field of industrial high-salt wastewater treatment. The method for separating and purifying industrial high-salt wastewater is realized by industrial high-salt wastewater separation and purification equipment, which includes a reactor, microwave radiators are fixedly nested on both sides of the reactor, a wastewater input pipe is fixedly penetrated on the top of the left side of the reactor, a wastewater output pipe is fixedly penetrated on the bottom of the left side of the reactor, a crystallized salt output pipe is fixedly penetrated on the bottom of the right side of the reactor, and a guide seat is nested in the bottom of the reactor through a bearing rotation. The invention can directly complete the drying and crushing of crystallized salt inside the reactor, and then more conveniently obtain the finished crystallized salt, improve the efficiency of obtaining the finished crystallized salt, and reduce the cost of obtaining the finished crystallized salt, which is more suitable for the treatment of industrial high-salt wastewater.

[0004] However, in this scheme, after crystallization and drying, the rotating disk descends along the outside of multiple hollow arc plates to scrape the crystallized salt coated on the outside of the hollow arc plates onto the guide seat. Since the guide seat is only a cone, it is difficult to transport the scraped crystallized salt particles to the outlet of the crystallized salt output pipe during rotation, resulting in poor discharge of the crystallized salt. In addition, its structural principle is to drive the rotating hollow arc plates in the wastewater for crystallization of the crystallized salt. Since the rotation in the wastewater will encounter resistance, combined with its structure, it can be seen that it only supports the upper end of the hollow arc plate, and the structural support stability is low, resulting in low equipment reliability.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1 , 2 As shown, in Example 1, an industrial waste salt purification device comprises a reactor body 1, and a microwave emitter 2 is provided on the side wall of the reactor body 1. In this embodiment, a groove is provided on the side wall of the reactor body 1, and the microwave emitter 2 is arranged in the groove. A crystal precipitation impeller 3 is fixedly provided in the reactor body 1, and a stirring guide impeller 4 is rotatably provided at the bottom of the reactor body 1. The stirring guide impeller 4 is transmission-connected with a stirring drive mechanism 5 fixed on the reactor body 1. An inlet and outlet liquid system is provided on the side wall of the reactor body 1, and a crystallized salt output port 6 is provided at the bottom of the reactor body 1. In this embodiment, the inlet and outlet liquid system comprises a liquid inlet 22 and a liquid outlet 23 provided on the side wall of the reactor body 1, and the liquid outlet 23 is located at the lower part of the side wall of the reactor body 1. Valves are provided on the liquid inlet 22 and the liquid outlet 23, and the valves are provided to control the discharge and discharge of wastewater. In addition, a scraper 7 is slidably provided on the crystallization impeller 3, and a screw assembly 8 is provided on the reactor body 1. The screw assembly 8 can be used to drive the scraper 7 to move. When the scraper slides along the crystallization impeller, the crystallized salt on the crystallization impeller is scraped off.

[0023] When this embodiment is used, wastewater containing industrial waste salt is input into the reactor body 1 through the liquid inlet 22, and then the microwave transmitter inside the reactor body 1 is started. The microwave transmitter performs microwave heating on the wastewater inside the reactor body 1, so that the salt in the wastewater crystallizes and precipitates to form crystalline salt. During the crystallization of salt, the stirring drive mechanism 5 drives the stirring guide impeller 4 to rotate, thereby driving the wastewater to rotate, and the crystallized salt precipitated in the wastewater adheres to the solution precipitation impeller. After collection, the wastewater is discharged from the liquid outlet, and then the microwave transmitter is turned on again to continue drying the residual moisture of the crystallized salt. After drying, the lead screw assembly drives the scraper to move downward, and the scraper scrapes off the crystallized salt attached to the crystallization precipitation impeller. At the same time, the footstep guide impeller at the bottom continues to rotate, and the fallen crystallized salt is moved to the crystallization salt output port for discharge.

[0024] Example 2, an industrial waste salt purification device, based on Example 1, as Figure 3 As shown, the stirring guide impeller 4 includes a central column 9 rotatably arranged at the bottom of the reactor body 1, the lower end of the central column 9 passes through the reactor body 1 and is transmission-connected to the stirring drive mechanism 5, and a plurality of blades 10 are arranged circumferentially of the central column 9. In addition, in this embodiment, the central column 9 and the blades 10 are arranged in a conical shape, and the conical arrangement can increase the stirring range of the blades, which is conducive to driving the wastewater to flow in the reactor body and promoting precipitation. In this embodiment, the central column is rotatably matched with the reactor body through a bearing, and a sealing ring or shaft seal for waterproof penetration is provided between the reactor body and the central column.

[0025] In addition, the stirring drive mechanism 5 includes a first drive motor 11 fixedly arranged below the reactor body 1 , and a drive shaft of the first drive motor 11 is transmission-connected to the central column 9 via a belt transmission pair 12 .

[0026] The crystallized salt output port 6 includes an output pipe segment 13 connected to the bottom of the reactor body 1. The lower end of the output pipe segment 13 is covered with a lower cover 14. The discharge of the purified crystallized salt is controlled by opening and closing the lower cover.

[0027] When in use, the first drive motor drives the central column to rotate through the belt transmission pair, and then drives the blades on the central column to rotate, so as to achieve the purpose of stirring the wastewater. When the crystallized salt needs to be discharged, the lower cover is opened, and the crystallized salt is scraped onto or between the blades by the scraper. As the blades rotate, the crystallized salt is driven to the top of the output pipe section, and the crystallized salt naturally falls into the output pipe section and is discharged from the output pipe section.

[0028] Embodiment 3, an industrial waste salt purification device, based on embodiment 2, the crystallization precipitation impeller 3 includes a fixed ring 15 fixedly connected to the inner wall of the reactor body 1, and a plurality of arc-shaped blades 16 are vertically arranged on the fixed ring 15. In this embodiment, two fixed rings are provided, which are respectively fixedly connected to the arc-shaped blades to form a stable support for the arc-shaped blades. In addition, the bending directions of the arc-shaped blades are consistent and are arranged at equal intervals along the circumference of the fixed ring. Secondly, the fixed ring at the lower end is inclined inwardly, which can guide the scraped crystallized salt, so that it can fall on the stirring guide impeller 4, which is beneficial to the subsequent discharging process of the crystallized salt.

[0029] The scraper 7 includes a scraper body 17 coaxially arranged with the fixing ring 15. The scraper body 17 is provided with a plurality of arc openings corresponding to the arc blades 16. The scraper body 17 is transmission-connected with the lead screw assembly 8 and the lead screw assembly 8 can drive the scraper body 17 to move vertically.

[0030] The screw assembly 8 includes a screw seat 18 fixedly connected to the fixing ring 15, a screw 19 is rotatably provided on the screw seat 18, a screw nut 20 for transmission cooperation with the screw 19 is fixedly provided on the scraper body 17, a second drive motor 21 is fixedly provided on the top of the reactor body 1, and the output shaft of the second drive motor 21 is connected to the screw 19 through a coupling.

[0031] When this embodiment is in use, when it is necessary to scrape off the crystallized salt attached to the curved blades, the second drive motor works to drive the lead screw to rotate, and then drives the scraper body downward under the cooperation of the lead screw and the lead screw nut, and the scraper body scrapes off the crystallized salt attached to the surface of the curved blades.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
