Under-floor heating pipe cleaning sand recovery device and under-floor heating pipe cleaning device comprising same

Abstract

The invention discloses an under-floor heating pipe cleaning sand recovery device. The device comprises a barrel body. The device is characterized in that: a filter screen is arranged in the barrel body; a cavity, namely, a filtering cavity, provided with a water inlet and a sand discharging opening is defined by the filter screen; an interlayer sleeve is arranged outside the filtering cavity; thedevice is also provided with a water outlet, a sand outgoing pipe and a water incoming pipe; the interlayer sleeve is communicated with the outside through the water outlet; one end of the sand outgoing pipe is connected with the sand discharging opening; the other end of the sand outgoing pipe is arranged outside the barrel body; one end of the water incoming pipe is connected with the water inlet; sand-water mixed liquid enters the filtering cavity through the water incoming pipe during cleaning; gravel is blocked by the filter screen, left in the filtering cavity and discharged through thesand discharging opening and the sand outgoing pipe; liquid penetrating through the filter screen is collected in the interlayer sleeve and discharged through the water outlet; and circulation is conducted in this way. Compared with the prior art, the device has the advantages of simple structure, good cleaning effect, convenience, practicability, convenience and quickness in cleaning sand recovery and the like.

Description

technical field [0001] The invention relates to a floor heating pipe cleaning sand recovery device and a floor heating pipe cleaning device. Background technique [0002] Compared with traditional heating, geothermal heating has the advantages of high heating efficiency, low water temperature attenuation rate, and uniform heating distribution. However, due to the relatively complicated pipeline arrangement, a large amount of metal ions (such as Ca, Mg) scale, sediment, and rust in the pipeline, resulting in pipeline blockage, poor water flow, and low heat dissipation efficiency. [0003] Chinese patent CN203991551 discloses a physical floor heating cleaning device. Its working principle is to use a positive pressure air pump to input air from the inlet of the pipeline to drive the collodion particles to remove the dirt on the inner wall of the pipeline through friction in the cleaned pipeline, and pass through the pipeline outlet. The negative pressure air pump and the posi...

AI Technical Summary

Problems solved by technology

The actual work has the following disadvantages: when the high-speed air in the pipeline drives the collodion in the pipe to clean the dirt, the collodion itself will not cause damage to the pipe wall due to its texture, but the dirt particles in the pipe after cleaning will inevitably have hard and sharp objects. Driven by the air, it will cause damage to the pipe and its narrow bends, resulting in water leakage and other consequences. Because of its certain plasticity, the collodion may be stuck in the narrow or bend of the pipe.

In actual work, it has the following disadvantages: the high-speed water flow cannot effectively clean the hard dirt on the pipe wall because of its relatively low friction, and the equipment is relatively complicated, and the cost investment for the cleaning result is too large

[0008] Chinese patent CN206670447U discloses a cleaning device for floor heating pipes. Its working principle is to mix the cleaning sand in the liquid, and mix the cleaning sand in the water flow, so that the cleaning sand enters the pipeline, and the pipeline is cleaned by friction between the cleaning sand and the inner wall of the pipeline. , after the cleaning is completed, the cleaning sand is recycled through a rotating gauze, that is, the recycling gauze in the cleaning state and the recovery state needs to be rotated and switched, the actual operation is more complicated, and the rotating gauze is in the working state and the recovery state When switching, its wear resistance is also to be tested
