Description

Technical Field

[0001] This utility model relates to the field of wastewater filtration technology, specifically to a wastewater filtration device with an easy-to-wash filter screen. Background Technology

[0002] Screen-type wastewater filtration equipment uses screens with different apertures to intercept large particles, suspended solids, and fibers in wastewater. For example, a microfiltration machine is a type of rotary screen filtration device. The wastewater to be treated enters the machine along the axial pipe inlet and flows out radially through the screen. Impurities in the water are trapped on the inner surface of the filter screen on the drum.

[0003] Chinese patent CN220460014U discloses a wastewater filtration device with an easy-to-replace filter screen. By setting up a locking block, scraper, and placement groove, it solves the problems that during use, only the waste filtered by the first filter screen is processed, causing the second filter screen to become clogged and unable to filter. Moreover, the wastewater filtration device does not allow for convenient replacement of the filter screen, which leads to clogging of the filter screen after long-term use, thus preventing wastewater from being discharged.

[0004] Although the above solution uses a retractable filter to facilitate cleaning and replacement, debris inside the pipe will remain inside when the filter is pulled out for cleaning, causing secondary pollution. Moreover, cleaning the filter by simply scraping the side of the pipe is not very effective.

[0005] Therefore, this utility model provides a wastewater filtration device with an easy-to-replace filter screen to solve the above problems. Utility Model Content

[0006] In view of the above situation and to overcome the defects of the prior art, this utility model provides a sewage filtration device that facilitates the replacement and cleaning of the filter screen. This solves the problem that when the filter screen is pulled out for cleaning, debris inside the pipe will remain inside the pipe, causing secondary pollution. Moreover, cleaning the filter screen inside the pipe by simply scraping the side of the pipe is not enough to achieve a good cleaning effect.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A wastewater filtration device that facilitates filter screen replacement includes a treatment tank. The treatment tank is fixedly connected to an inlet pipe, a cleaning pipe, a sewage pipe, and a drain pipe. A motor is installed on the treatment tank. The output shaft of the motor is fixedly connected to a cross baffle. A rubber sealing block is fixedly connected to one side of the cross baffle near the treatment tank. Two mounting slots are provided on the cross baffle, and a filter screen is installed in each of the two mounting slots.

[0009] Preferably, two fixing brackets 1 are fixedly connected to both sides of the treatment tank, and two fixing brackets 2 are provided on both sides of the treatment tank. The two ends of the fixing brackets 2 are fixedly connected to the two fixing brackets 1 respectively, and each fixing bracket 1 is fixedly connected to an installation block.

[0010] Preferably, the water inlet pipe and the cleaning pipe are located above the two filter screens, and the cleaning pipe is detachably fitted with a plug.

[0011] Preferably, the cleaning tube is fixedly connected to two sets of connecting plates, each of which is fitted with a screw. One end of the screw is fixedly connected to a plug, and the other end of the screw is threaded with a nut.

[0012] Preferably, a fixing plate is fixedly connected to the filter screen, and a locking bolt is installed on the fixing plate, and the locking bolt is threaded to the cross baffle.

[0013] Preferably, a positioning block is fixedly connected to the fixing plate, and a positioning groove matching the positioning block is provided on the cross baffle.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The treatment tank is divided into an inlet chamber, a cleaning chamber, a sewage discharge chamber, and a drain chamber by a cross baffle. The cross baffle is rotated 180 degrees by a motor, which can transfer the impurities filtered and trapped by the filter screen in the inlet chamber to the cleaning chamber for treatment. The transfer and treatment of impurities can be achieved without removing the filter screen, avoiding secondary pollution caused by impurities remaining in the pipeline. At the same time, it ensures the continuity of the filtration process and reduces equipment downtime caused by cleaning or replacing the filter screen.

[0016] 2. The filter screen is fixedly connected to the cross baffle by locking bolts on the fixing plate, and the positioning block on the fixing plate matches the positioning groove of the cross baffle. This not only realizes the quick installation and removal of the filter screen, but also improves the installation stability of the filter screen on the cross baffle through the cooperation of the positioning block and the positioning groove.

[0017] 3. Water is sprayed into the cleaning chamber through the cleaning pipe to clean the filter screen, with the filter screen's filtration surface facing the drain chamber. This allows impurities to be directly flushed into the drain chamber and discharged during water spraying. The cross baffle can be rotated to move the filter screen to be cleaned into the cleaning chamber, positioning its filtration surface for easy rinsing. With the help of directional water spraying and proper switching of the filter screen's position, impurities trapped on the filter screen's surface can be removed more thoroughly, effectively ensuring the filter screen's filtration efficiency and extending its service life.

[0023] The following will refer to the attached reference. Figures 1 to 4 The various embodiments of this utility model will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.

[0024] A wastewater filtration device with easy-to-wash filter screen includes a treatment tank 1. Two fixing frames 7 are fixedly connected to both sides of the treatment tank 1. Fixing frames 8 are provided on both sides of the treatment tank 1, and the two ends of the fixing frames 8 are fixedly connected to the two fixing frames 7 respectively. Each fixing frame 7 is fixedly connected to an installation block 9.

[0025] The treatment tank 1 is supported by the frame structure formed by the second fixing bracket 8 and the first fixing bracket 7, and the frame structure is fixed by the mounting block 9, thereby fixing the treatment tank 1.

[0026] Specifically, the treatment tank 1 is fixedly connected to an inlet pipe 2, a cleaning pipe 3, a sewage pipe 5, and a drain pipe 6. The inlet pipe 2, the cleaning pipe 3, the drain pipe 6, and the drain pipe 6 are arranged clockwise on the treatment tank 1. A motor 10 is installed on the treatment tank 1. The output shaft of the motor 10 is fixedly connected to a cross baffle 11. A rubber sealing block 12 is fixedly connected to one side of the cross baffle 11 near the treatment tank 1. Two mounting slots 13 are opened on the cross baffle 11, and a filter screen 14 is installed in each of the two mounting slots 13.

[0027] The treatment tank 1 is divided clockwise into an inlet chamber, a cleaning chamber, a sewage discharge chamber, and a drain chamber by a cross baffle 11. The inlet pipe 2 is connected to the inlet chamber, the cleaning pipe 3 is connected to the cleaning chamber, the drain pipe 6 is connected to the sewage discharge chamber, and the sewage discharge pipe 5 is connected to the drain chamber. The domestic sewage in the inlet chamber is filtered by the filter screen 14, and the filtered water falls into the drain chamber.

[0028] The water inlet pipe 2 and the cleaning pipe 3 are located above the two filters 14 respectively, and the cleaning pipe 3 is detachably equipped with a plug 4.

[0029] In this embodiment, two sets of connecting plates 15 are fixedly connected to the upper part of the cleaning tube 3. Each connecting plate 15 is fitted with a screw 16. One end of the screw 16 is fixedly connected to the plug 4, and the other end of the screw 16 is threaded with a nut 17.

[0030] When installing the plug 4, the screw 16 on the plug 4 needs to be inserted into the connecting plate 15, and the nut 17 needs to be threaded on to fix the plug 4.

[0031] A fixing plate 18 is fixedly connected to the filter screen 14. A locking bolt 21 is installed on the fixing plate 18 and is threaded onto the cross baffle 11.

[0032] The fixing plates 18 on the two filters 14 are in opposite positions in the horizontal direction, that is, the two fixing plates 18 are located in the cleaning chamber and the drain chamber respectively. The fixing plate 18 above the filter 14 in the cleaning chamber can facilitate the cleaning of the filter 14.

[0033] Since the filter surface of the filter screen 14 in the cleaning chamber is located in the drain chamber, water can be sprayed above the filter screen 14 to facilitate cleaning. The filter surface of the filter screen 14 in the water inlet chamber faces upward, so that impurities can be filtered and retained in the water inlet chamber. After the cross baffle 11 is rotated 180 degrees clockwise, the impurities can be transferred to the cleaning chamber.

[0034] A positioning block 19 is fixedly connected to the fixing plate 18, and a positioning groove 20 matching the positioning block 19 is provided on the cross baffle 11. The positioning block 19 and the positioning groove 20 are used to position the fixing plate 18, thereby improving the stability of the fixing plate 18 on the cross baffle 11.
