Description

Technical Field

[0001] The utility model relates to the technical field of sewage crystallization treatment and processing, in particular to a sewage crystallization treatment device. Background Art

[0002] Wastewater crystallization treatment is a method that utilizes the principle of solubility change of substances under specific conditions to convert soluble substances in wastewater into crystalline form, thereby realizing resource recovery in wastewater. During the treatment process, the wastewater is first pretreated and then enters the crystallizer. In the crystallizer, the temperature, pressure, pH value and other conditions are adjusted to make the soluble substances in the wastewater reach an oversaturated state, and then crystals are precipitated.

[0003] Steam crystallization is a commonly used treatment method for sewage crystallization. During the process of steam crystallization of sewage by sewage steam crystallization device, the crystals produced are easy to adhere to the inner wall of the device. The existing steam crystallization device will be equipped with a stirring structure inside. While steam crystallizing the sewage, the crystals adhering to the inner wall of the device will be removed. However, this stirring structure is vertically arranged inside the crystallization device. When the crystals produced by crystallization are large, the crystals will accumulate at the bottom of the crystallization device and contact with the stirring structure over a large area, which will produce greater resistance to the stirring structure, affect the normal rotation of the stirring structure, and even cause the stirring structure to malfunction and short-circuit, affecting subsequent use, which is very inconvenient. Utility Model Content

[0004] Based on the above description, the utility model provides a sewage crystallization treatment device to solve the problem that the stirring device provided in the existing sewage steam crystallization device will be blocked by crystals and affect rotation after a large amount of crystals are accumulated, and may even cause a short circuit failure of the stirring structure.

[0007] Furthermore, both ends of the crystallizer are semicircular, and a discharge port and a planar boss are respectively provided in the center of both ends of the crystallizer. A first through hole is opened in the center of the planar boss away from the discharge port. A feed port and an exhaust port are provided on the surface of the crystallizer, and the exhaust port is located at one end of the feed port close to the planar boss.

[0008] Furthermore, the positioning structure is composed of a partition and a bearing seat, the partition is installed on the inner side of the crystallizer and is located at one end of the exhaust port close to the planar boss, and the side of the partition close to the discharge port is inclined toward the exhaust port.

[0009] Furthermore, a second through hole is provided at the center of one side of the partition near the planar boss, the diameter of the second through hole is equal to the diameter of the first through hole, and a mounting groove is provided on the inner side of the second through hole near one end of the discharge port, and the bearing seat is installed on the inner wall of the mounting groove near the center of one end of the planar boss.

[0010] Furthermore, the driving assembly is composed of a driving motor and a coupling, the driving motor is installed on the surface of the planar boss, the output shaft of the driving motor passes through the first through hole and extends to the inside of the crystallizer, and the coupling is installed at one end of the driving motor output shaft close to the discharge port.

[0011] Furthermore, the stirring structure is composed of a movable rod, a support rod and a spiral blade. The movable rod is installed on the inner side of the bearing seat, and the end of the movable rod close to the planar boss is installed and connected to the coupling.

When used in conjunction with the threaded spiral blade, the structure occupies a small space and has a small contact area, which effectively reduces the force area when in contact with the crystal. Under the output of the driving motor, the spiral blade can stably penetrate the accumulated crystals in the crystallizer and rotate, and guide the crystals adhered to the inner wall of the crystallizer to the discharge port, thereby reducing the occurrence of short-circuit failures in the stirring process, ensuring the service life of the equipment, and facilitating the discharge of the crystals.

The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0023] See also Figure 1-4 The utility model is a sewage crystallization treatment device, comprising a crystallizer 1, a driving assembly is installed at one end of the crystallizer 1, a positioning structure for separating spaces is arranged inside the crystallizer 1, a stirring structure is installed in the positioning structure, which is fitted to the inner wall of the crystallizer 1 and connected to the driving assembly, and the stirring structure is spiral and has a conical end.

[0024] See also Figure 1Both ends of the crystallizer 1 are semicircular, and a discharge port 11 and a plane boss 14 are respectively arranged in the center of both ends of the crystallizer 1. The arrangement of the semicircular end of the crystallizer 1 facilitates the crystals to slide along the inner wall and concentrate at the discharge port 11 to complete the discharge of the crystals. A first through hole 15 is provided in the center of the plane boss 14 away from the discharge port 11. A feed port 12 and an exhaust port 13 are arranged on the surface of the crystallizer 1. The exhaust port 13 is located at one end of the feed port 12 close to the plane boss 14. The exhaust port 13 is higher than the feed port 12, and the enclosed space is large. When the crystallizer 1 works on sewage crystallization, the exhaust port 13 can, under the blocking cooperation of the partition 4, guide as much water vapor as possible to discharge the crystallizer 1 at the top of the crystallizer 1 to avoid the water vapor remaining in the crystallizer 1 being re-condensed into liquid to affect the crystallization efficiency.

[0025] See also Figure 1 The positioning structure is composed of a partition 4 and a bearing seat 5. The partition 4 is installed on the inner side of the crystallizer 1 and is located at one end of the exhaust port 13 close to the plane boss 14. The side of the partition 4 close to the discharge port 11 is inclined toward the exhaust port 13. A second through hole 41 is opened in the center of the side of the partition 4 close to the plane boss 14. The diameter of the second through hole 41 is equal to the diameter of the first through hole 15. A mounting groove 42 is opened at one end of the inner side of the second through hole 41 close to the discharge port 11. The bearing seat 5 is installed in the center of the inner wall of the mounting groove 42 close to one end of the plane boss 14. The partition 4 plays the role of partitioning space in the crystallizer 1. The partition 4 is installed through the bearing seat 5 and the movable rod 6 to form a sealed partition of the space inside the crystallizer 1 to prevent the steam generated during the operation of the crystallizer 1 from diffusing to the plane boss 14 and causing rust and short circuit to the drive motor 2 and the coupling 3. At the same time, the partition 4 can also guide the steam generated during the crystallization operation of the crystallizer 1 to the exhaust port 13 through the inclined side, thereby facilitating the steam discharge for treatment.

[0026] See also Figure 1 The driving assembly consists of a driving motor 2 and a coupling 3. The driving motor 2 is installed on the surface of the planar boss 14. The output shaft of the driving motor 2 passes through the first through hole 15 and extends to the inside of the crystallizer 1. The coupling 3 is installed at one end of the output shaft of the driving motor 2 close to the discharge port 11. The driving motor 2 is a servo motor with a model of ECMA-E21320SS. After being connected and fixed to the movable rod 6 through the coupling 3, the movable rod 6 can be driven to rotate at a uniform speed in the bearing seat 5.

[0027] See also Figure 1The stirring structure is composed of a movable rod 6, a support rod 61 and a spiral blade 7. The movable rod 6 is installed on the inner side of the bearing seat 5, and the end of the movable rod 6 close to the plane boss 14 is installed and connected to the coupling 3. The support rod 61 is arranged on the surface of the movable rod 6 at one end close to the discharge port 11 and is arranged in a cross shape. The movable rod 6 is dispersedly arranged, and the spiral blade 7 can be cross-fixed to increase stability. The spiral blade 7 is installed at the end of the support rod 61 that is away from each other. The end of the spiral blade 7 close to the discharge port 11 is tapered. The spiral blade 7 The outer side of the crystallizer 1 is in contact with the inner wall of the crystallizer 1. The spiral blade 7 can scrape off the crystals adhered to the inner wall of the crystallizer 1 when rotating, and can also push the crystals to the discharge port 11 to facilitate the discharge of the crystals. The spiral blade 7 is not in vertical contact with the accumulated crystals, but is inserted in a threaded shape. When used in conjunction with the movable rod 6, the contact surface is small. When rotating, the resistance generated by the spiral blade 7 and the accumulated crystals in the crystallizer 1 is also small, which will not affect the normal rotation of the spiral blade 7, thereby reducing the occurrence of short-circuit failures during the stirring process and ensuring the service life of the equipment.
