Stepless adjustable wastewater ratio regulator

Abstract

The invention provides an adjustable stepless waste water proportional regulator. The regulator comprises a motor (1), a valve element (2) and a regulator body (4), wherein a motor shaft of the motor (1) is in mechanical connection with the valve element (2) and drives the valve element (2); the upper portion of the valve element (2) is provided with an external thread (21), and the lower portion of the valve element (2) is an adjusting end (24); the upper portion of the valve element is provided with a mechanism which is in mechanical connection with the motor shaft of the motor (1); and the regulator body (4) is provided with a three-way pipe structure, and one passage is provided with an internal thread (41) matched with the external thread (21) of the valve element. The adjustable stepless waste water proportional regulator is simple in structure and applicable to various types of water purifiers. The regulator is mounted on the downstream of the concentrated water outlet end and can play a role of stepless regulation of the waste water ratio, and accordingly water production of the water purifiers as required can be met.

Description

【Technical field】 [0001] The invention relates to a waste water ratio regulator, in particular to a regulator capable of realizing stepless adjustment of the waste water ratio. 【Background technique】 [0002] The wastewater ratio regulator is a type of device commonly used in water purifiers, especially those using reverse osmosis membranes and nanofiltration membrane water purifiers. It is a device that adjusts the ratio of wastewater by changing the concentrated water pipeline pressure of the membrane filter element. [0003] Existing waste water proportioners suitable for water purifiers are generally divided into "fixed" waste water ratio and "grading type" manual adjustment of waste water ratio. The limitations of these two types of wastewater ratio regulators are: first, they are either not adjustable at all, or can only be adjusted in several gears (levels) to adjust the ratio of wastewater, and they cannot automatically and continuously adjust the ratio of wastewater...

AI Technical Summary

Problems solved by technology

The limitations of these two types of wastewater ratio regulators are: first, they are either not adjustable at all, or can only be adjusted in several gears (levels) to adjust the ratio of wastewater, and they cannot automatically and continuously adjust the ratio of wastewater according to water quality. In order to deal with different water quality (TDS) more accurately, and finally achieve the best balance between protective film performance and efficient water saving

Second, after a period of use, the waste water scaler is prone to fouling, which will cause membrane blockage, and in severe cases, the water purification equipment will be scrapped

The above two types of wastewater proportioners either cannot be descaled at all (only parts can be replaced), or can only be manually intervened to perform manual descaling. Neither of them can realize automatic descaling in response to changes in the working conditions of the proportioner to ensure clean water The equipment can always operate under the best working conditions

This leads to increased after-sales maintenance costs and poor user experience
