Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, and more specifically, to a wastewater treatment device for a thermal power plant. Background Art

[0002] In the daily operations of thermal power plants, wastewater treatment systems are a key link in ensuring environmentally friendly emissions. Filter plates, as core components of wastewater treatment equipment, have a direct impact on the overall system's treatment effectiveness due to their efficiency. However, existing wastewater treatment equipment often presents operational difficulties during the installation and removal of filter plates, posing a significant challenge for maintenance personnel. Frequent installation and removal is not only time-consuming and labor-intensive, but can also damage the filter plates and the equipment itself.

[0003] The design of existing wastewater treatment devices in thermal power plants fails to fully consider the need for rapid installation and removal of filter plates. As a result, in actual operation, maintenance personnel need to spend a lot of time on complex installation steps. Due to the unreasonable design of the connection structure between the filter plate and the device, it often requires the collaboration of multiple people and the use of professional tools to complete the installation or replacement. This not only increases maintenance costs but also reduces maintenance efficiency. In emergency situations, this cumbersome operation process may delay troubleshooting and affect the normal operation of the thermal power plant. Utility Model Content

[0008] The present invention is further configured such that a positioning groove is provided at the bottom end of the fixing sleeve, and a positioning block is provided at the bottom end of the clamping tube.

[0009] The utility model is further configured such that most positioning grooves and positioning blocks are configured as polygons and are adapted to each other. The cooperation between the polygonal positioning grooves and the positioning blocks ensures the precise position of the card tube in the fixing sleeve, prevents the card tube from rotating and deflecting, and improves the accuracy and stability of the installation.

[0010] The utility model is further configured such that limiting grooves are provided in multiple groups of the limiting sleeves, limiting sliders are installed on the outsides of multiple groups of the clamping blocks, and multiple groups of the limiting sliders are slidably installed in the limiting grooves. The cooperation between the limiting grooves and the limiting sliders ensures the movement trajectory of the clamping blocks in the limiting sleeves, prevents the clamping blocks from deflecting and shaking, and improves the stability and reliability of the entire mechanism.

[0011] The utility model is further configured as follows: the fixed sleeve is provided with a quick release mechanism, the quick release mechanism includes a rotating sleeve, a transmission sleeve, a push block and a resist block, the transmission sleeve is rotatably mounted on the top surface of the fixed sleeve, the transmission sleeve is slidably mounted on the fixed sleeve, the push block is mounted on the bottom end of the transmission sleeve, and the resist block is mounted on the top surfaces of multiple groups of resist blocks.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the present invention provides a wastewater treatment device for a thermal power plant, which has the following beneficial effects:

[0017] 1. The beneficial effects of the filtering mechanism are reflected in: a stable filtering channel is established through the reliable connection between the connecting pipe and the conveying pipe, the fixing sleeve is installed at the bottom end of the connecting pipe to form a solid supporting structure, the clamping tube is set in the fixing sleeve and fixes the filter plate to form a preliminary filtering unit. This modular design is not only convenient for installation and maintenance, but also improves the filtering efficiency. At the same time, the cooperation between the polygonal positioning groove and the positioning block effectively prevents the rotation of the clamping tube, ensuring the stability and reliability of the filtering device.

[0018] 2. The beneficial effects of the quick-lock mechanism are as follows: by arranging multiple sets of installation grooves and limit sleeves on the inner wall of the fixed sleeve, and coordinating the combination of the card block, push spring and card slot, an automatic locking function is achieved. The limit grooves in the limit sleeve and the limit slider on the outside of the card block form a precise guide system, ensuring that the card block can only move on the predetermined track. When the card tube is inserted, the card block automatically embeds into the card slot under the action of the push spring, forming a reliable lock. This design not only improves installation efficiency, but also ensures the reliability of locking through multiple guides.

[0019] 3. The beneficial effects of the quick-release mechanism are as follows: a smooth and controllable transmission effect is achieved through the threaded connection between the rotating sleeve and the transmission sleeve. The push block at the bottom of the transmission sleeve is guided by the slide groove and accurately pushes the resistance block to act on the card block, so that the card block overcomes the push spring force and exits the card slot. This mechanical transmission method is not only easy to operate, but also has stable and reliable transmission. At the same time, the sealing groove at the bottom of the transmission sleeve cooperates with the sealing strip on the top surface of the card tube to form a reliable sealing structure to prevent medium leakage. The entire quick-release process does not require tools, which greatly improves maintenance efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

The delivery pipe 1 is provided with a filtering mechanism, the filtering mechanism including a connecting pipe 2, a fixing sleeve 3, a clamping pipe 4, a filter plate 21 and a quick clamping mechanism. The connecting pipe 2 is installed at one end of the delivery pipe 1, the fixing sleeve 3 is installed at the bottom end of the connecting pipe 2, the clamping pipe 4 is arranged in the fixing sleeve 3, the quick clamping mechanism includes a mounting groove 5, a limiting sleeve 6, a clamping block 7, a push spring 8 and a clamping groove 9. The mounting groove 5 is provided with multiple groups distributed on the inner wall of the fixing sleeve 3, the limiting sleeve 6 is installed in multiple groups of mounting grooves 5, the clamping block 7 is provided with multiple groups arranged in the fixing sleeve 3, the push spring 8 is provided with multiple groups and the two ends are respectively connected to the clamping block 7 and the limiting sleeve 6, the clamping groove 9 is provided with multiple groups distributed on the outer wall of the clamping pipe 4, and the filter plate 21 is fixed in the clamping pipe 4.

[0030] A positioning groove 10 is provided at the bottom end of the fixing sleeve 3 , and a positioning block 11 is provided at the bottom end of the clamping tube 4 .

[0031] Most of the positioning grooves 10 and positioning blocks 11 are configured as polygons and are adapted to each other. The positioning groove 10 at the bottom of the fixing sleeve 3 and the positioning block 11 at the bottom of the clamping tube 4 are designed as polygons, and the two are adapted to each other to form a precise positioning structure.

[0032] Limiting grooves 12 are provided in multiple groups of limiting sleeves 6, and limiting sliders 13 are installed on the outside of multiple groups of clamping blocks 7. Multiple groups of limiting sliders 13 are slidably installed in the limiting grooves 12. The limiting grooves 12 provided in the limiting sleeves 6 cooperate with the limiting sliders 13 on the outside of the clamping blocks 7 to form a guide limiting structure.

[0033] In this embodiment, when the filter plate needs to be installed, it is connected to the delivery pipe 1 through the connecting pipe 2, and the card tube 4 is inserted into the fixed sleeve 3. At this time, the polygonal positioning block 11 cooperates with the positioning groove 10 to prevent the card tube 4 from rotating. During the insertion process, the multiple groups of card grooves 9 on the outer wall of the card tube 4 contact the card block 7 in the fixed sleeve 3, pushing the card block 7 to compress the push spring 8 and slide along the limit groove 12. When the card tube 4 is fully inserted into place, under the action of the push spring 8, the card block 7 automatically pops into the card groove 9 to achieve quick locking. The cooperation between the limit sleeve 6 and the limit slider 13 ensures that the card block 7 can only move on the predetermined track, thereby improving the reliability of the locking. At the same time, the cooperation between the sealing strip 20 and the sealing groove 19 ensures the sealing performance of the connection.

[0034] See also Figure 5 As an implementation method of the quick release mechanism: a quick release mechanism is provided on the fixed sleeve 3, and the quick release mechanism includes a rotating sleeve 14, a transmission sleeve 15, a push block 16 and a stop block 17. The transmission sleeve 15 is rotatably installed on the top surface of the fixed sleeve 3, the transmission sleeve 15 is slidably installed on the fixed sleeve 3, the push block 16 is installed at the bottom end of the transmission sleeve 15, and the stop block 17 is installed on the top surface of multiple groups of stop blocks 17.

[0035] The inner side of the rotating sleeve 14 and the outer wall of the transmission sleeve 15 are arranged to be threadedly connected, and the inner side of the rotating sleeve 14 and the outer wall of the transmission sleeve 15 are threadedly connected to form a transmission mechanism.

[0036] A sliding groove 18 is provided on the outer wall of the clamping tube 4 , and multiple groups of push blocks 16 are slidably installed in the sliding groove 18 . The sliding groove 18 provided on the outer wall of the clamping tube 4 and the push blocks 16 slide together to form a sliding mechanism.

[0037] A sealing groove 19 is formed at the bottom of the transmission sleeve 15 and a sealing strip 20 is formed on the top of the clamping tube 4. The sealing groove 19 at the bottom of the transmission sleeve 15 cooperates with the sealing strip 20 on the top of the clamping tube 4 to form a sealing structure.

[0038] More specifically, when the filter device needs to be disassembled or replaced, the rotating sleeve 14 is rotated to drive the transmission sleeve 15 to move downward through the threaded connection. The push block 16 at the bottom of the transmission sleeve 15 slides along the slide groove 18 on the outer wall of the card tube 4, and at the same time pushes the block 17 to move inward. The block 17 pushes the card block 7 to overcome the force of the push spring 8 and exit the card slot 9, releasing the locked state. At this time, the card tube 4 can be easily taken out and quick disassembly can be achieved.

[0039] In summary, when the overall equipment is in use or running: when the filter plate needs to be installed, it is connected to the delivery pipe 1 through the connecting pipe 2, and the card tube 4 is inserted into the fixed sleeve 3. At this time, the polygonal positioning block 11 cooperates with the positioning groove 10 to prevent the card tube 4 from rotating. During the insertion process, the multiple groups of card grooves 9 on the outer wall of the card tube 4 contact the card block 7 in the fixed sleeve 3, pushing the card block 7 to compress the push spring 8 and slide along the limit groove 12. When the card tube 4 is fully inserted into place, under the action of the push spring 8, the card block 7 automatically pops into the card groove 9 to achieve quick locking. The cooperation between the limit sleeve 6 and the limit slider 13 ensures that the card block 7 can only move on the predetermined track, thereby improving the reliability of the locking. At the same time, the cooperation between the sealing strip 20 and the sealing groove 19 ensures the sealing performance of the connection.

[0040] When the filter device needs to be disassembled or replaced, the rotating sleeve 14 is rotated to drive the transmission sleeve 15 to move downward through the threaded connection. The push block 16 at the bottom of the transmission sleeve 15 slides along the slide groove 18 on the outer wall of the card tube 4, and at the same time pushes the stop block 17 to move inward. The stop block 17 pushes the card block 7 to overcome the force of the push spring 8 and exit the card groove 9, releasing the locked state. At this time, the card tube 4 can be easily taken out, and quick disassembly is achieved.

[0041] In all the schemes mentioned above, the connection between the two components can be selected according to actual conditions by welding, bolt and nut connection, bolt or screw connection or other well-known connection methods, which will not be listed here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
