Backfill equipment of ground buried pipe of ground source heat pump

Abstract

The invention relates to backfill equipment of a ground buried pipe of a ground source heat pump, which comprises a stand, wherein a hydraulic device, stirring devices and a beating device are arranged in the stand, the hydraulic device is respectively connected with the stirring devices and the beating device, the stirring devices are arranged at both sides of the upper part in the stand, the beating device is arranged at the bottom in the stand and positioned below a space between the stirring devices at both sides of the upper part in the stand, and the discharge ports of the stirring devices correspond to a loading hopper of the beating device. When in use, water is firstly added for test run, then materials are added into the stirring devices after everything is normal, the evenly stirred materials flow into the loading hopper of the beating device through the discharge ports of the stirring devices after the materials are evenly stirred by a stirring plate, and the materials are extruded from an outlet hose joint through a transition nozzle by the pressing of a hydraulic cylinder and a piston rod. The invention integrates a stirring system and a grouting system into a whole, realizes full hydraulic drive, has forceful and stable power, aims at the characteristic of the construction of the ground source heat pump and is designed and manufactured for all-weather field construction.

Description

technical field [0001] The invention relates to equipment for geothermal construction, in particular to equipment for backfilling buried pipes of ground source heat pumps. Background technique [0002] At present, domestic backfilling of buried pipes is done by manually mixing cement, sand, water, etc. and then filling them with shovels. The disadvantages are that the backfilling speed is slow, the mixing is uneven, the backfilling is not solid, and voids are prone to appear, which is not conducive to heat exchange and thermal efficiency. Low, waste energy, resulting in high operating costs for users. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a ground source heat pump buried pipe backfill equipment that is convenient for transportation and installation, easy to operate and use, easy to maintain and repair, and can meet all grouting filling needs in environmental prot...
