Jam-proof automatic filth-discharging recharging device

Abstract

The invention relates to an anti-plug automatic blowdown recharge device used for water-source heat pump collection well, which includes: well tube and recharge pipe controlled by return valve and connected to the water-source heat pump and assembled in the well tube. And the technical points includes that: automatic control powerful blowdown pump is arranged at bottom of the water return level in the well tube, and the pump body of the blowdown pump is integrated with double-channel non-plug impeller comprised by main, vice impellers, and terminal fixed stirrer of motor shaft equipped with the main, vice impellers, and the stirrer is arranged in channel under a clapboard in base water inlet cavity of the blowdown pump, and outlet end of the pump body is connected to sedimentation pond outside the well tube via muddy water straw. The invention can fully resolve the problem of well tube plug existing in current technology, and can reduce the amount of recharge well and desterilize disabled well as well as save operation cost and maintain cost, prolong the service life of the collection well.

Description

technical field [0001] The invention relates to a water source heat pump heat collecting well recharge device, in particular to a water source heat pump unit heat collector well for single tube well recharge or multi-tube well recharge to prevent sedimentation of fine sand and suspended matter from clogging the well pipe Anti-clogging automatic sewage refilling device. Background technique [0002] At present, the development and utilization of geothermal resources have been widely promoted and applied in industries such as heating, aquaculture, and breeding. Water source heat pump units are energy-collecting devices that use heat-collecting wells to exchange heat with groundwater. The heat collector wells of water source heat pump units can be divided into single-tube wells (that is, the tasks of pumping and recharging in the same tube well) and multi-tube wells (that is, one tube well pumps water and multiple tube wells recharge) according to the distribution of their rech...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide an anti-clogging automatic sewage drainage and refilling device, which can fundamentally solve the problem of well pipe clogging in the prior art. The thorough dredging effect and recharge effect, and the ability to fully extract heat can effectively reduce the number of recharge wells and reuse abandoned wells, and also achieve the saving of operation and maintenance costs of heat collection wells and prolong their use. purpose of life
