Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a membrane treatment device for chemical wastewater treatment. Background Technology

[0002] Wastewater treatment and recycling are effective measures for developing and utilizing water resources. Chemical wastewater is an important source of wastewater for wastewater treatment. MBR membrane treatment is a new type of wastewater treatment technology that combines membrane separation units and biological treatment units. It has the advantages of high efficiency, good water quality, and small footprint.

[0003] For example, the patent application document with application number 202222811388.6 discloses a membrane treatment device for chemical wastewater treatment. This utility model discloses a membrane treatment device for chemical wastewater treatment, including a treatment box, a cleaning component and an auxiliary sewage discharge component, as well as water inlet pipes and drain pipes installed on the upper and lower sides of the treatment box. The cleaning component includes a filter screen that is movably installed in the center of the inside of the treatment box. The chemical wastewater treatment membrane equipment described in this utility model includes a filter screen and a filter membrane inside the treatment tank. After use, during the rotation driven by the geared motor, the inner and outer walls are uniformly cleaned by a spray pipe, thereby removing the dirt adhering to the inner and outer ends and improving the subsequent filtration effect of the filter screen and filter membrane. The bottom of the filter screen and filter membrane has a liftable sealing plate, which can be adjusted during the cleaning process, so that the cleaned wastewater inside the filter screen and filter membrane can be discharged through the drain pipe at the bottom of the treatment tank along the guide plate. However, when this chemical wastewater treatment membrane equipment is in use, simply spraying the filter membrane is not effective in cleaning and filtering the filter membrane if it encounters large impurities.

[0004] Therefore, in view of this, we have studied and improved the existing structure to propose a membrane treatment equipment for chemical wastewater treatment. Utility Model Content

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figures 1-3 As shown, a membrane treatment device for chemical wastewater includes a wastewater tank 1. A rotating base 101 is rotatably mounted in the middle of the wastewater tank 1, and an agitator 2 is provided on the outer surface of the rotating base 101. A driven gear 201 is mounted on the upper surface of the rotating base 101, and a rotating bearing 202 is rotatably mounted on the upper surface of the driven gear 201. In this technical solution, the driven gear 201 can drive the agitator 2 to rotate, agitating the wastewater inside the wastewater tank 1, preventing the wastewater from settling inside the wastewater tank 1, and improving the filtration effect of the membrane fiber filter body 204.

[0016] Furthermore, a driven gear 203 is mounted on the upper surface of the rotating bearing 202, and a membrane filter device body 204 is mounted on the upper surface of the driven gear 203. A branch suction pipe 205 is provided on the upper surface of the membrane filter device body 204. In this technical solution, the driven gear 203 can be used to control the rotation of the membrane filter device body 204, so that it generates centrifugal force and removes impurities adhering to the surface of the membrane filter device body 204 by radial shear water flow, thus preventing impurities from clogging the surface of the membrane filter device body 204 and affecting the filtration effect.

[0017] Furthermore, a main negative pressure suction pipe 206 is installed on the upper surface of the branch suction pipe 205, and a return water pipe 208 is provided on the outer surface of the main negative pressure suction pipe 206. A solenoid valve 207 is provided on the outer surface of the return water pipe 208. With this technical solution, by setting the solenoid valve 207, the water inside the return water pipe 208 can enter the interior of the main negative pressure suction pipe 206 through the opening and closing of the solenoid valve 207 to help clean the membrane fiber filter body 204.

[0018] Furthermore, an electric lifting rod 3 is installed on the right side of the rotating base 101, and a support plate 301 is provided on the upper surface of the electric lifting rod 3. In this technical solution, the electric lifting rod 3 can drive the drive gear 303 to rise and fall, so that it can switch to mesh with the driven gear 1 201 and the driven gear 2 203 to make the stirring blade 2 rotate or make the membrane fiber filter device body 204 rotate, and switch between the two modes.

[0019] Furthermore, a drive motor 302 is provided at the end of the support plate 301, and a drive gear 303 is provided at the output end of the drive motor 302. The drive gear 303 is meshed with the driven gear 201, and the drive gear 303 and the driven gear 203 are meshed after being raised and lowered by the electric lifting rod 3. In this technical solution, the rotation of the driven gear 201 and the driven gear 203 can be controlled by the setting of the drive gear 303.

[0020] Working Principle: When using this chemical wastewater treatment membrane equipment, firstly, the drive motor 302 is started to drive the drive gear 303 to rotate. Through meshing, the driven gear 201 rotates, which in turn drives the stirring blades 2 mounted on the rotating base 101 to rotate, thus agitating the wastewater inside the wastewater tank 1. Simultaneously, the main negative pressure suction pipe 206 generates negative pressure suction, which is transmitted through the branch suction pipe 205 to the interior of the membrane fiber filter body 204. This allows the wastewater to pass through the membrane fibers and then enter the main negative pressure suction pipe 206 to complete the filtration process. When further filtration is needed on the membrane fibers... When cleaning the filter body 204, simply activate the electric lifting rod 3 to move the support plate 301 upwards, causing the drive gear 303 to mesh with the driven gear 203. Then, activate the drive motor 302 to rotate the membrane filter body 204. Centrifugal force causes impurities on the outer surface of the membrane filter body 204 to fall off. Simultaneously, the solenoid valve 207 opens, allowing clean water to be sprayed out from inside the membrane filter body 204 through the return water pipe 208 and the main negative pressure suction pipe 206, thus assisting in cleaning the impurities. This is the working principle of this chemical wastewater treatment membrane treatment equipment.
