specific Embodiment approach 1

[0018]Specific embodiment 1: As shown in Figure 1 and Figure 2, the filter surface non-blocking and anti-blocking device of this embodiment consists of an outer shell 1, a rotating filter cartridge 3, a water inlet area 4-1 in the cylinder, and a water outlet area 4- in the cylinder. 2. The transmission device that drives the rotary filter cartridge 3 to rotate 5, the water inlet 6 outside the cartridge, the drain outlet 7 outside the cartridge, the outlet 8 of the water inlet area inside the cartridge, and the inlet 9 of the water outlet area inside the cartridge. The water inlet 6 and the drain outlet 7 outside the cylinder, the rotary filter cartridge 3 is arranged inside the outer casing 1, and the inside of the rotary filter cartridge 3 is divided into the water inlet area 4-1 in the cylinder and the water outlet area 4-2 in the cylinder, the water inlet area in the cylinder The water area 4-1 communicates with the outlet 8 of the water inlet area in the cylinder, and the ...

specific Embodiment approach 2

[0019] Specific embodiment two: as shown in Figure 3, according to actual needs, a hairbrush 10 can also be added in the anti-blocking device. The surfaces of the barrel 3 are in contact. When the anti-blocking device is in operation, the hair brush 10 is stationary, and the rotating filter surface is cleaned under the rotation of the rotating filter cartridge 3 . The increase of hairbrush 10 is to clean the dirt that hangs on the wall and cannot be backwashed on the filter surface, and plays an auxiliary cleaning effect when the backwash effect is not good, so as to ensure the cleaning effect of the filter surface.

[0020] Working principle: When the anti-blocking device is working, the transmission device 5 such as the motor and reducer drives the rotatable filter cartridge 3 to rotate, and the filter surface is continuously exchanged between the water inlet area 4-1 and the water outlet area 4-2 in the cylinder, and the rotation The speed is adjustable. The sewage enters...

specific Embodiment approach 3

[0021] Specific embodiment three: As shown in Figure 4, the secondary pump system of this embodiment is composed of primary pump 11, sewage and surface water source heat pump non-blocking pressure balance anti-blocking device 13, secondary pump 14, heat exchanger 15, connection The pipeline 12 and the drainage pipeline 16 are composed. The primary pump 11 communicates with the water inlet 6 outside the cylinder of the anti-blocking device 13 through the connecting pipeline 12, and the inlet of the secondary pump 14 is connected with the cylinder of the anti-blocking device 13 through the connecting pipeline 12. The outlet 8 of the inner water inlet area is connected, the outlet of the secondary pump 14 is connected with the inlet of the heat exchanger 15 through the connecting pipeline 12, and the outlet of the heat exchanger 15 is connected with the inlet of the inner water outlet area of ​​the anti-blocking device 13 through the connecting pipeline 12 9 communicates, and the ...

Abstract

The invention relates to a non-resistance pressure balance anti-resistance device of heat pump of ground water, and relative system, wherein the outer frame (1) of anti-resistance device has external water inlet (6) and external water outlet (7); the rotation filter cylinder (3) is inside the outer frame (1); the rotation filter cylinder (3) is divided into internal water inlet area (4-1) and internal water outlet area (4-2); the internal water inlet area (4-1) is connected to the internal water inlet area outlet (8) and the internal water outlet area (4-2) is connected to the internal water outlet area inlet (9). The invention has stable water pressure and stable flux, with small size and low cost.

Description

technical field [0001] The invention relates to an improvement of a filter surface non-blocking anti-blocking device when sewage and surface water sources (urban sewage, river and lake water, sea water, etc.) are used as low-level cold and heat sources of a heat pump. Background technique [0002] Using sewage and surface water sources as heat pump cold and heat sources to heat and air-condition buildings has important energy-saving and environmental protection values. It is one of the effective ways to alleviate energy consumption and reduce environmental pollution. However, it is necessary to effectively and economically solve the technical problems of water sources. Sewage and surface water both contain suspended matter, and heat exchange equipment can easily cause "instantaneous" blockage during the process of extracting heat or cooling by the heat pump. Although the relative content of suspended solids in surface water is not high, due to the large water consumption, th...
