Description

Technical Field

[0001] This utility model belongs to the field of geothermal equipment technology, specifically relating to a ground source heat pump pipeline flow regulation device. Background Technology

[0002] Existing ground source heat pump pipeline systems suffer from several drawbacks: First, traditional flow regulation mechanisms (such as valves or baffles) are prone to malfunction and reduced accuracy when operating in media containing impurities due to particle blockage or wear, making it impossible to stably maintain the set flow rate and severely impacting the system's heat exchange efficiency. Second, commonly used fixed filtration devices (such as single-layer metal mesh or filter bags) quickly become clogged after intercepting impurities, leading to a sharp increase in water flow resistance and a sudden drop in flow rate. This necessitates frequent shutdowns for disassembly, cleaning, or filter replacement, resulting in high maintenance costs and interruptions to continuous system operation. Furthermore, existing filtration devices generally lack self-cleaning capabilities to actively remove attached impurities. The continuous accumulation of impurities not only accelerates clogging but may also breed microorganisms, forming stubborn biodegradation, further deteriorating filtration performance and contaminating the system. The drainage design also has significant shortcomings; the rudimentary drainage outlets often require the system to be shut down or partially shut down during operation. The current technology often separates flow regulation components from filtration components, resulting in inefficient sewage discharge during operation. This leads to the accumulation of impurities in dead corners, causing secondary pollution or blockages. More importantly, existing technologies typically separate flow regulation components from filtration components, resulting in a dispersed structure, large space occupation, and complex piping. In particular, the moving parts of the regulation components (such as valve cores) are directly exposed to the unfiltered medium, making them susceptible to wear and jamming due to impurities, significantly reducing reliability and lifespan. At the same time, the repeated movement of the regulation components and the influence of impurities can easily lead to seal failure, causing media leakage or the infiltration of external contaminants, threatening system safety. These defects together lead to frequent system failures, increased downtime, and high maintenance costs. There is an urgent need to develop an integrated device that can integrate precise flow regulation, efficient dual filtration, automatic anti-clogging scraping, convenient sewage discharge, and reliable sealing functions to comprehensively improve the stability, efficiency, and lifespan of ground source heat pump pipeline systems. Utility Model Content

[0003] The purpose of this invention is to provide a ground source heat pump pipeline flow regulation device, which aims to solve the problems mentioned in the background art.

[0005] Workbench;

[0006] An adjustable sewage discharge assembly is located on the outer wall of the workbench. The assembly includes a heat pump body, a delivery pipe, an adjusting pipe, a mounting base, a sealing ring, a metal mesh, a sewage discharge pipe, a drive rod, a conical block, a scraper, and a drive component. The heat pump body is fixedly positioned at the top center of the outer wall of the workbench. The delivery pipe is connected to the heat pump body, and the adjusting pipe is connected to the delivery pipe. The mounting base is embedded in the inner wall of the adjusting pipe, the sealing ring is embedded in the inner wall of the adjusting pipe, the metal mesh is rotatably embedded in the inner wall of the adjusting pipe, the sewage discharge pipe is embedded in the inner wall of the adjusting pipe, and the metal mesh is rotatably inserted into the outer wall of one end of the sewage discharge pipe. The drive rod is inserted into the center of the outer wall of the conical block, and the conical block is slidably inserted into the inner wall of the mounting base. The conical block and the sealing ring are matched. The scraper is embedded in the inner wall of the adjusting pipe and matches the metal mesh. The drive component is located on the inner wall of the adjusting pipe.

[0007] Furthermore, the drive assembly includes a drive blade and a connecting rod. The drive blade is fixedly disposed on the outer wall of one end of the connecting rod and sleeved on the outer wall of the drive rod. The other end of the connecting rod is fixedly disposed on the inner wall of the metal mesh.

[0008] Furthermore, the inner wall of the metal mesh is embedded with a non-woven fabric layer.

[0009] Furthermore, a reset spring is embedded in the inner wall of the mounting base, and the reset spring is sleeved on the outer wall of one end of the conical block.

[0011] Furthermore, the bottom end of the sewage pipe is connected to a valve via a flexible hose and installed in an external waste collection device.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The conical block is moved by an external cylinder to change the gap between it and the sealing ring, achieving convenient and reliable flow regulation and ensuring sealing. When the medium flows through the regulating pipe, it passes through the non-woven fabric layer embedded in the metal mesh and the metal mesh itself for double high-efficiency filtration, intercepting impurities of different particle sizes, improving the cleanliness of the medium and protecting the equipment. The design of the non-woven fabric layer attached to the metal mesh allows for quick replacement and facilitates maintenance. The medium flow drives the fan blade to rotate, which in turn drives the metal mesh to rotate. With the help of the fixed scraper, impurities attached to the surface of the non-woven fabric are scraped off in time, effectively preventing blockage and ensuring that the filtration channel is unobstructed. The stripped impurities are collected with the water flow to the drain pipe and connected to the external collection device for quick and thorough discharge, maintaining system cleanliness. When the driving force is lost, the return spring automatically pushes the conical block to return to its original position and presses the sealing ring to ensure sealing safety in the non-regulating state. The guide cone at the end of the mounting base guides the water flow smoothly, reducing turbulence and ensuring regulation stability. The overall structure is firmly connected, the drive component and the metal mesh are reliably combined, and the drain channel design is simple, significantly reducing maintenance difficulty and workload. This component integrates precise flow control, high-efficiency filtration, self-cleaning anti-clogging, and convenient drain maintenance functions, comprehensively improving the operating efficiency, reliability and service life of the ground source heat pump pipeline system.

[0026] In a specific embodiment of this utility model, the drain assembly is adjusted, and the heat pump body 2 drives the pipeline. When the flow rate needs to be adjusted, the external cylinder drives the drive rod 9 to move, which drives the cone block 10 to overcome the return spring 12, so that the cone block 10 moves away from the mounting seat 5. At this time, the cone block 10 moves away from the sealing ring 6, and the medium flows through the conveying pipeline 3. It flows into the interior of the regulating pipe 4 through the gap between the sealing ring 6 and the cone block 10. The water source is filtered through the non-woven fabric layer and then filtered twice through the metal mesh 7 before flowing out. The non-woven fabric layer is attached to the metal mesh 7 and has a quick replacement function. The drain pipe 8 collects impurities on the non-woven fabric and discharges them quickly. The drive fan blade 13 drives the connecting rod 14 and the metal mesh 7 to rotate. The scraper 15 prevents impurities from accumulating on the non-woven fabric and ensures the rapid discharge of impurities.

[0035] Specifically, the bottom end of the sewage pipe 8 is connected to a valve via a flexible hose and installed in an external waste collection device.

[0036] In a specific embodiment of this utility model, the bottom end of the sewage pipe 8 is connected to a valve via a flexible hose and installed in an external waste collection device to ensure cleanliness.

[0037] Working principle:

[0038] Adjusting the sewage discharge component, the heat pump body 2 drives the pipeline. When the flow rate needs to be adjusted, the external cylinder drives the drive rod 9 to move, which drives the cone block 10 to overcome the return spring 12, so that the cone block 10 moves away from the mounting seat 5. At this time, the cone block 10 moves away from the sealing ring 6, and the medium flows through the conveying pipeline 3. It flows into the interior of the regulating pipe 4 through the gap between the sealing ring 6 and the cone block 10. The water source is filtered through the non-woven fabric layer and then filtered twice through the metal mesh 7 before flowing out. The non-woven fabric layer is attached to the metal mesh 7 and has a quick replacement function. The sewage pipe 8 collects impurities on the non-woven fabric and discharges them quickly. The drive fan blade 13 drives the connecting rod 14 and the metal mesh 7 to rotate. Through the scraper 15, impurities are prevented from accumulating on the non-woven fabric, ensuring the rapid discharge of impurities.
