Abstract
Description
Technical Field
[0001] This utility model belongs to the field of ring cooling technology, specifically relating to a novel fluid circulation device for a liquid-sealed ring cooler. Background Technology
[0002] Liquid-sealed ring coolers use a liquid medium (mainly water) for sealing, offering advantages such as better sealing and lower air leakage compared to traditional blower-type coolers. However, during operation, existing sealed ring coolers experience slurry formation due to the mixing of internal dust and water, which creates resistance to the cooler's transmission. When this resistance reaches a critical value, it causes equipment failure and shutdown.
[0003] Further as Figure 4 The existing circulation method shown has the following problems: the valve is in a platformless position for a long time as the circulator rotates, which poses a safety risk of accidents when the operator controls the valve. Secondly, if the connecting pipe is blocked, it is not only a safety hazard when the operator clears the connecting pipe, but also requires the equipment to be shut down for maintenance, resulting in a lot of expenses. Utility Model Content
[0004] This invention provides a novel fluid circulation device for a liquid-sealed ring cooler, aiming to solve the problems of mud accumulation, personnel operation risks, and easy blockage of connecting pipes in the above-mentioned background art.
[0005] To achieve the above objectives, the technical solution of this utility model is: a novel fluid circulation device for a liquid-sealed ring cooler, comprising an upper sealing groove, a lower sealing groove, a sedimentation tank, a purification tank, and a circulation pump, characterized in that: an electric stirrer is fixedly attached to the upper sealing groove, the electric stirrer comprising a motor, a reducer, and an impeller, the motor drive end being connected to the impeller via the reducer, the impeller being located within the upper sealing groove, a siphon tube being provided within the upper sealing groove, the inlet end of the siphon tube being inserted into the upper sealing groove, the outlet end of the siphon tube being inserted into the lower sealing groove, and a first valve being provided on the siphon tube.
[0006] Furthermore, a flexible tube is connected to the middle of the siphon tube, and the flexible tube is equipped with a second valve.
[0007] Furthermore, a scraper is welded to the edge of the impeller.
[0008] Furthermore, the impeller is made of corrosion-resistant stainless steel.
[0009] The beneficial effects of this invention are as follows: The electric agitator installed on the device, driven by a motor, reduces the speed and impeller, agitates the slurry deposited at the bottom of the upper sealing groove, preventing slurry blockage and thus avoiding circulation interruption. The siphon pipe is less prone to clogging than a connecting pipe. If blockage occurs, the flexible hose connected in the middle of the siphon pipe can be flushed and cleared by injecting high-pressure water through an external water supply pipe. Personnel can also disassemble and clear the blockage without shutting down the machine, reducing personnel safety risks and maintenance costs. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0016] like Figure 1-3 As shown, a novel fluid circulation device for a liquid-sealed ring cooler includes an upper sealing groove 1, a lower sealing groove 2, a sedimentation tank 12, a purification tank 13, and a circulation pump 14. The device is characterized in that: an electric stirrer 6 is fixedly attached to the upper sealing groove 1; the electric stirrer 6 includes a motor 3, a reducer 4, and an impeller 5; the drive end of the motor 3 is connected to the impeller 5 through the reducer 4; the impeller 5 is located within the upper sealing groove 1; a siphon pipe 7 is installed within the upper sealing groove 1; the inlet end of the siphon pipe 7 is inserted into the upper sealing groove 1, and the outlet end of the siphon pipe 7 is inserted into the lower sealing groove 2; a first valve 8, which is a DN40 valve, is provided on the siphon pipe 7.
[0017] Furthermore, a flexible hose 9 is connected to the middle of the siphon pipe 7. The flexible hose 9 is connected to a high-pressure water supply pipe. If a blockage occurs, water is injected through the high-pressure water supply pipe to flush and clear the blockage. At the same time, the flexible hose 9 is equipped with a second valve 10, which is a DN15 valve, to control the water supply pipe to clear the blockage.
[0018] Furthermore, a scraper is welded to the edge of impeller 5 to enhance the mud agitation effect. Meanwhile, impeller 5 is made of corrosion-resistant stainless steel, which extends the service life of the equipment and reduces maintenance costs.
[0019] In use, first, fix the electric mixer 6 to the upper sealing groove 1. Based on the depth of the upper sealing groove 1 (h=300mm), make an impeller 5 with a diameter of 520mm. Start the motor 3 (specifically model YE3-90S-4) to drive the impeller 5 to rotate, stirring the slurry in the upper sealing groove 1. Simultaneously, the reducer 4 (specifically model XWD8105) can control the speed of the impeller 5 according to actual conditions. This process cleans the slurry at the bottom of the upper sealing groove 1, solving the problem of slurry accumulation causing blockages and resulting in machine malfunctions and shutdowns.
[0020] Next, the siphon pipe 7 is positioned behind the impeller 5, with the direction confirmed by the rotation direction of the annular cooler. The water inlet end of the siphon pipe 7 is vertically inserted into the upper sealing groove 1, with its port 30mm from the bottom of the sealing groove 1. During fluid circulation, the DN40 valve 8 is closed and the DN15 valve 10 is opened. When the siphon pipe 7 is full of water, the DN15 valve 10 is closed and the DN40 valve 8 is opened. The fluid continuously flows through the upper sealing groove 1 into the lower sealing groove 2, and then flows into the sedimentation tank 12 through the drain outlet of the sewage discharge trough 11. After sedimentation, in the purification tank 13, the fluid is injected back into the upper sealing groove 1 by the circulation pump 14, completing the circulation process. During this process, the siphon pipe 7 is not easily clogged, and personnel do not need to control the valves in the platform-less position, ensuring personnel safety. When a blockage occurs, it can be cleared not only by connecting the water supply pipe in the middle of the siphon pipe 7, but also by disassembling and clearing while the equipment is in operation, reducing maintenance costs and extending the service life of the equipment.
