Description

Technical Field

[0001] This utility model relates to the field of wastewater crystallization treatment technology, and in particular to a wastewater heating crystallization separation treatment device. Background Technology

[0002] With the acceleration of industrialization, wastewater discharge is increasing year by year, making the efficient treatment of pollutants in wastewater and its resource utilization an urgent problem to be solved. In wastewater treatment technology, heating crystallization separation is an important process, which precipitates dissolved substances in wastewater to form crystals, thereby achieving solid-liquid separation and resource recovery. However, traditional wastewater treatment devices still face many technical bottlenecks in practical applications, requiring urgent improvement and optimization.

[0003] Currently, existing wastewater treatment devices suffer from the following problems in the filtration and crystallization separation stages: First, in the filtration stage, floating debris in the wastewater easily adheres to the surface of the filter plates, leading to decreased filtration efficiency or even clogging, thus affecting the treatment effect. Simultaneously, the filtered-down floating debris often absorbs a large amount of wastewater; if not cleaned or treated promptly, it may cause secondary pollution in subsequent stages. Second, in the crystallization separation stage, the crystals formed on the inner wall of the crystallization tank are difficult to effectively scrape off and collect, usually requiring manual cleaning or the use of complex equipment, resulting in cumbersome operation, low efficiency, and increased maintenance costs. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a wastewater heating crystallization separation treatment device. This device uses a filter plate to intercept floating debris, and a hydraulic rod to push a squeezing plate to clean and squeeze the floating debris, preventing blockage and reducing secondary pollution. A spiral scraper removes crystals from the inner wall of the crystallization tank and transports them for collection, simplifying the process and eliminating cleaning hassles.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wastewater heating crystallization separation treatment device, comprising a crystallization tank, a scraper connected inside the crystallization tank via a rotating assembly, an electric heating tube fixedly connected to the inner wall of the crystallization tank, a solenoid valve fixedly connected to the lower right side of the crystallization tank, a first support fixedly connected to the outer surface of the lower end of the crystallization tank, a connecting pipe fixedly connected to the outer surface of the top end of the crystallization tank, a filter box fixedly connected to the upper end of the connecting pipe, a door slidably connected to the right end of the filter box, a filter plate connected to the inner wall of the filter box via a linkage assembly, and a water inlet pipe fixedly connected to the top of the filter box.

[0006] Furthermore, the rotating assembly includes a motor fixedly connected to the left end of the crystallization tank, a stirring shaft fixedly connected to the drive end of the motor, a stirrer fixedly connected to the outer wall of the stirring shaft, and a scraper fixedly connected to one end of the stirrer.

[0007] Furthermore, the linkage component includes a hydraulic rod fixedly connected to the inner wall of the left end of the filter box, a pressing plate fixedly connected to the driving end of the hydraulic rod, the pressing plate being slidably connected to the upper end of the filter plate, and the filter plate and the filter box being slidably connected.

[0008] Furthermore, a second bracket is fixedly connected to the lower end of the filter box, and the second bracket is fixedly connected to the upper surface of the crystallization tank.

[0009] Furthermore, the stirring shaft is rotatably connected to the crystallization tank, and a support plate is fixedly connected to the lower end of the motor.

[0010] Furthermore, the extrusion plate and the filter box are slidably connected.

[0011] Furthermore, the support plate is fixedly connected to the left end of the crystallization tank.

[0012] This utility model has the following beneficial effects:

[0013] 1. In this invention, a filter plate effectively intercepts various floating debris mixed in with wastewater. Then, a hydraulic rod is activated, its drive end pushing a pressing plate tightly against the upper surface of the filter plate and moving it downwards. This not only pushes the floating debris accumulated on the filter plate surface to the tank door but also applies pressure to the floating debris, squeezing out a large amount of wastewater absorbed inside. In this way, the filter plate is cleaned promptly, effectively avoiding clogging caused by the accumulation of floating debris, and reducing the potential secondary pollution to the environment caused by floating debris in subsequent treatment processes.

[0014] 2. In this invention, a spiral scraper removes the crystals formed on the inner wall of the crystallization tank and transports them along the spiral direction to the position above the solenoid valve on the right end of the crystallization tank. After the crystallization process is complete, simply opening the solenoid valve allows for convenient and quick collection of the crystals. This design not only simplifies the crystal collection process but also avoids the hassle of tedious cleaning of the crystallization tank due to crystals adhering to the tank wall.

[0020] 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.

[0021] Reference Figures 1-3 This utility model provides an embodiment of a wastewater heating crystallization separation treatment device, comprising a crystallization tank 1, a motor 2 fixedly connected to the left end of the crystallization tank 1, a support plate 3 fixedly connected to the lower end of the motor 2, the support plate 3 fixedly connected to the left end of the crystallization tank 1, a stirring shaft 4 fixedly connected to the drive end of the motor 2, the stirring shaft 4 being rotatably connected to the crystallization tank 1, a stirrer 5 fixedly connected to the outer wall of the stirring shaft 4, a scraper 6 fixedly connected to one end of the stirrer 5, a heating element 7 fixedly connected to the inner wall of the crystallization tank 1, a solenoid valve 8 fixedly connected to the lower right side of the crystallization tank 1, and a first support 9 fixedly connected to the lower outer surface of the crystallization tank 1. A connecting pipe 10 is fixedly connected to the outer surface of the top of the tank 1. A filter box 12 is fixedly connected to the upper end of the connecting pipe 10. A second support 11 is fixedly connected to the lower end of the filter box 12. The second support 11 is fixedly connected to the upper surface of the crystallization tank 1. A door 13 is slidably connected to the right end of the filter box 12. A hydraulic rod 14 is fixedly connected to the inner wall of the left end of the filter box 12. An extrusion plate 15 is fixedly connected to the driving end of the hydraulic rod 14. The extrusion plate 15 is slidably connected to the upper end of the filter plate 16. The filter plate 16 and the filter box 12 are slidably connected. The extrusion plate 15 and the filter box 12 are slidably connected. A water inlet pipe 17 is fixedly connected to the top of the filter box 12.

[0022] Specifically, when using this device to treat wastewater, the wastewater to be treated is first introduced into the filter box 12 through the inlet pipe 17. As the wastewater slowly flows through the filter plate 16, the filter plate 16 effectively intercepts various floating objects mixed in the wastewater. The filtered wastewater then flows smoothly into the crystallization tank 1 through the connecting pipe 10, preparing for subsequent treatment. At this time, the hydraulic rod 14 is activated, and its drive end pushes the extrusion plate 15 to tightly adhere to the upper surface of the filter plate 16 and move downwards. This action not only pushes the floating objects accumulated on the surface of the filter plate 16 to the box door 13, but also applies pressure to the floating objects, squeezing out a large amount of wastewater absorbed inside. In this way, the filter plate 16 is cleaned in time, effectively avoiding the clogging problem caused by the accumulation of floating objects, and reducing the secondary pollution that floating objects may cause to the environment in subsequent treatment stages. After the water in the floating objects has been fully squeezed out, the treated floating objects can be taken out and properly disposed of simply by opening the box door 13. After the wastewater enters the crystallization tank 1, the heating element 7 is turned on to heat the wastewater inside the tank. Simultaneously, the motor 2 is started, driving the stirring shaft 4 to rotate, thus activating the agitator 5. The continuous rotation of the agitator 5 ensures comprehensive stirring of the wastewater, guaranteeing uniform heating and significantly improving crystallization efficiency. At the same time, the spiral scraper 6 rotates synchronously with the agitator 5. Due to the unique spiral structure of the scraper 6, it easily scrapes off the crystals formed on the inner wall of the crystallization tank 1 during rotation and transports them along the spiral direction to the position above the solenoid valve 8 on the right side of the crystallization tank 1. After the crystallization process is complete, simply opening the solenoid valve 8 allows for convenient and quick collection of the crystals. This design not only simplifies the crystal collection process but also avoids the hassle of tedious cleaning of the crystallization tank 1 due to crystals adhering to the tank wall.

[0023] Working principle: When using this device, wastewater is first drawn into the filter box 12 through the inlet pipe 17. When the wastewater passes through the filter plate 16, the filter plate 16 will filter out the floating matter mixed in the wastewater. The filtered wastewater enters the crystallization tank 1 through the connecting pipe 10. The hydraulic rod 14 is activated, and the driving end of the hydraulic rod 14 will push the extrusion plate 15 to move downward close to the upper surface of the filter plate 16, thereby pushing the floating matter filtered down the surface of the filter plate 16 to the box door 13 and squeezing the floating matter. After the water in the floating matter is squeezed out completely, the box door 13 is opened to remove the floating matter for processing. After the wastewater enters the crystallization tank 1, the electric heating tube 7 is turned on to heat the wastewater. At the same time, the motor 2 is turned on. The drive end of the motor 2 drives the stirring shaft 4 to rotate, and the stirrer 5 rotates accordingly to stir the wastewater, making it heat evenly and accelerating the crystallization efficiency. The scraper 6 rotates with the rotation of the stirrer 5. Since the scraper 6 is spiral, the crystals generated on the inner wall of the crystallization tank 1 are scraped off and transported by the spiral scraper 6 to the top of the solenoid valve 8 at the right end of the crystallization tank 1. When the crystallization is completed, the solenoid valve 8 can be opened to collect the crystals.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
