Description

Technical Field

[0001] This utility model relates to a water treatment device based on inclined plate filtration. Background Technology

[0002] Among the wastewater treatment equipment in the aquaculture industry, microfiltration machines are the most commonly used filtration equipment. Microfiltration machines use roller-type filter screens, which have a relatively complex structure, making the filter screens easy to damage. Moreover, microfiltration machines consume a lot of power, generally more than 15 million kilowatts.

[0003] There are many other existing filtration devices, such as Chinese Patent CN 114797211A, which discloses an inclined plate filter tank, including a filter tank and a drain pipe. A valve is fixed to the drain pipe. A support shaft rotatably connects to the filter tank. A filter plate is fixed to the support shaft inside the filter tank. The filter plate has evenly distributed filter holes penetrating it. Support rings are symmetrically fixed to both ends of the filter plate. A connecting plate is provided between the two support rings. A rotating shaft is fixed to both ends of the connecting plate, passing through the corresponding support rings and rotatably connecting to them. A drain trough is also fixed to one side of the filter tank on one side of the connecting plate, with a drain outlet at the end of the trough. A drain pipe is also fixed to the bottom of the filter tank. This device has a relatively complex filtration structure and requires valve control and adjustment to achieve drainage, making operation complicated.

[0004] Therefore, it is necessary to design a new type of filtration device. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a water treatment device based on inclined plate filtration, which has a simple structure, good practicality and low energy consumption.

[0006] The technical solution of the utility model is as follows: A water treatment device based on inclined plate filtration includes a tank, an inclined filter plate, a sludge collection basket, an inlet pipe, and an outlet pipe; the inclined filter plate is installed in the tank at an angle (i.e., at an angle to the horizontal plane). The water inlet pipe is installed on the water tank and above the filter inclined plate, with the inlet of the water inlet pipe facing the filter surface of the filter inclined plate. The sludge collection basket is installed in the pool body and located below the lower end of the filter inclined plate; The drain pipe is located at the bottom of the pool.

[0007] Preferably, there are two drain pipes to improve drainage efficiency. Alternatively, there can be only one drain pipe, and the pipe diameter can be designed according to the drainage volume.

[0008] It also includes a slant plate bracket; the filter slant plate is installed on the slant plate bracket; The inclined plate bracket is fixed in the pool body at an angle. Specifically, it is fixed to the inner side of two opposite side plates of the pool body.

[0009] The tilt angle of the filter plate is 15-65 degrees. Preferably, the tilt angle is 30-45 degrees. A tilt angle of 20 degrees is also possible. This angle is relative to the horizontal plane.

[0010] Side guards are provided on both sides of the filter slant. The filter screen and guards can also be designed as a single unit.

[0011] The water outlet end of the inlet pipe has an elbow. Preferably, the water outlet direction is perpendicular to the filter screen, which facilitates the direct spraying of water onto the filter screen.

[0012] A manual valve is installed on the inlet pipe for easy flow adjustment. Furthermore, the water pump connected to the inlet pipe is controlled by a frequency converter, allowing the flow rate to be adjusted by changing the frequency.

[0013] There are multiple water inlet pipes, and these multiple water inlet pipes are arranged in parallel.

[0014] The inclined plate bracket is equipped with nozzles for backwashing. These high-pressure nozzles facilitate backwashing of the filter screen.

[0015] The pool can be square, or it can be round or other shapes.

[0016] The lower end of the inclined plate bracket has a limiting block for limiting the position of the filter inclined plate.

[0017] The sludge collection basket is a drawer-type sludge collection module, including a basket body and a basket support bracket for supporting the basket body. The basket body can be inserted into and removed from the bracket. In the normal state, the basket body is inserted into the bracket. Since the water level is not high and it is located below the basket body, it will not interfere with the operation of the basket body. When it is necessary to clean the waste residue, the basket body can be pulled out, which is convenient for operation.

[0018] The bottom of the pool is the pool base 6, which makes the pool more stable. Beneficial effects

[0019] This utility model discloses a water treatment device based on inclined plate filtration, which is a novel filtration equipment. Compared with drum-type microfilters, it has a simpler structure and lower energy consumption (only a low-power water pump is needed, with power as low as 500W). It uses a drawer-type sludge collection basket, making manual cleaning convenient. In summary, this filtration device has a simple structure, low manufacturing cost, good filtration effect, and is easy to promote and implement. Attached Figure Description

Detailed Implementation

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: Example 1

[0028] like Figure 1-6 A water treatment device based on inclined plate filtration includes a tank body 1, an inclined filter plate 5, a sludge collection basket 9, an inlet pipe, and an outlet pipe 8; the inclined filter plate is installed in the tank body at an angle; the angle of inclination of the inclined filter plate is preferably 20 degrees. This angle is relative to the horizontal plane.

[0029] The water inlet pipe is installed on the water tank and above the filter inclined plate, with the inlet of the water inlet pipe facing the filter surface of the filter inclined plate. The sludge collection basket is installed in the pool body and located below the lower end of the filter inclined plate; The drain pipe is located at the bottom of the pool.

[0030] There are two drainage pipes located on opposite side walls of the pool to improve drainage efficiency.

[0031] The device also includes a slant plate bracket 10; the filter slant plate is mounted on the slant plate bracket; The inclined plate bracket is fixed in the pool body at an angle (20 degrees). Specifically, it is fixed to the inner side of the two opposite side plates of the pool body.

[0032] Side guard plates 2 are provided on both sides of the filter inclined plate. The filter screen is made of 150-200 mm steel wire mesh. The steel wire mesh is fixed to the frame 51. The frame, filter screen and guard plates can also be an integrated design.

[0033] The water outlet end of the inlet pipe has an elbow. The water outlet direction is perpendicular to the filter screen, which makes it easy for the water to be sprayed directly onto the filter screen.

[0034] A manual valve is installed on the inlet pipe for easy flow adjustment. Furthermore, the water pump connected to the inlet pipe is controlled by a frequency converter, allowing the flow rate to be adjusted by changing the frequency.

[0035] There are three water inlet pipes, and the three water inlet pipes are arranged in parallel.

[0036] The inclined plate bracket is equipped with nozzles for backwashing. These high-pressure nozzles facilitate backwashing of the filter screen.

[0037] The pool can be square, or it can be round or other shapes.

[0038] The lower end of the inclined plate bracket has a limiting block 11 for limiting the position of the filter inclined plate to prevent the filter inclined plate from sliding downward.

[0039] The sludge collection basket is a drawer-type sludge collection module, including a basket body and a sludge collection basket bracket 4 for supporting the basket body. The basket body can be inserted and pulled out on the bracket. In the normal state, the basket body is inserted into the bracket. Since the water level is not high and it is located below the basket body, it will not interfere with the operation of the basket body. When it is necessary to clean the waste residue, the basket body can be pulled out, which is convenient for operation.

[0040] The bottom of the pool is the pool base 6, which makes the pool more stable.

[0041] The inclined plate bracket is equipped with nozzles for backwashing (not shown in the figure). The nozzles are high-pressure nozzles, which facilitate backwashing of the filter screen.

[0042] The working process of this device is as follows: Wastewater requiring filtration enters the inlet pipe via a water pump, and then flows out through the inlet pipe to flush the filter screen; clean water passes through the filter screen, collects at the bottom of the tank, and then flows through the drain pipe into the next stage of water treatment (such as entering the biological treatment tank); debris (such as uneaten feed, fish feces, etc.) flows down the top of the filter screen and into the sludge collection basket for collection. The surface of the sludge collection basket is a relatively dense permeable medium (such as fabric) that can block impurities; when the debris in the sludge collection basket reaches a certain level, it is cleaned manually by pulling out the sludge collection basket, emptying the debris, and rinsing it clean with water.
