[0001] This utility model belongs to the field of filter tanks, and in particular relates to a sludge treatment sludge discharge pipe filter tank. Background Technology

[0002] The sludge treatment system of the water plant is responsible for the disposal of sludge and the reuse of supernatant. The sludge water treated by the sludge treatment system contains debris such as leaves, tree roots, and plastic bags. The sludge water containing debris enters the sludge treatment lift pump. The debris in the sewage cannot be filtered and will enter the lift pump, which will have an adverse effect on the safe operation of the lift pump. Summary of the Invention

[0003] In view of this, the present invention aims to propose a sludge treatment discharge pipe filter tank to solve the technical problem that the sludge water being treated in the sludge treatment system contains debris such as leaves, tree roots, and plastic bags. When the sludge water containing debris enters the sludge treatment lift pump, the debris in the sewage cannot be filtered and will enter the lift pump, causing adverse effects on the lift pump.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A sludge treatment sludge discharge pipe filter tank includes a filter tank body, with an inlet pipe and an outlet pipe respectively connected to both sides of the filter tank body. A filter assembly is disposed inside the filter tank body, and the filter assembly includes:

[0006] The filter plate includes an inclined filter plate and a horizontal filter plate, which divides the filter tank into a first chamber and a second chamber. The first chamber is connected to the sludge inlet pipe, and the second chamber is connected to the sludge outlet pipe.

[0007] Furthermore, the top of the filter tank is covered with a sealing cap, and the top of the sealing cap is fixedly connected to an exhaust pipe, on which an exhaust valve is installed.

[0008] Furthermore, a vent pipe is fixedly connected to the bottom end of the filter tank, and a vent valve is installed on the vent pipe.

[0009] Furthermore, the filter tank is provided with a support body inside, which includes an arc-shaped support and an inclined support, both of which are fixedly connected to the inner wall of the filter tank.

[0010] Furthermore, a support frame is fixedly connected to the edge of the filter plate. The support frame includes an arc-shaped frame and an inclined frame. A first support rod and a second support rod are respectively disposed on the surface of the arc-shaped frame and the inclined frame. A lower pressure plate is fixedly connected between the top of the first support rod and the second support rod, and the lower pressure plate is in contact with the bottom of the sealing cover.

[0011] Furthermore, a connecting ring is fixedly connected to the surface of the filter tank, and the connecting ring is fixedly connected to the sealing cover by bolts.

[0012] Compared with the prior art, the sludge treatment discharge pipe filter tank of this utility model has the following advantages:

[0013] Beneficial effects:

[0014] (1) In the filtration process described in this utility model, mud and water will enter the first chamber of the filter tank through the mud inlet pipe, and then enter the second chamber after being filtered by the filter plate. The mud and water entering the second chamber will be discharged through the mud outlet pipe and then enter the lifting pump, thus preventing impurities in the mud and water from entering the lifting pump, which is beneficial to protecting the lifting pump.

[0015] By dividing the filter plates into inclined and horizontal plates, the water flow on the inclined plates is laminar due to the smaller hydraulic radius, which is conducive to sedimentation. The inclined plates increase the settling area of ​​the particles, accelerate the settling speed of the particles, and make it more difficult for impurities to remain on the filter plates, so as not to affect the flow rate.

[0016] (2) In this utility model, after the lower pressure plate is pressed against the sealing cover, the lower pressure plate will press against the support frame through the first support rod and the second support rod, thereby pressing the filter plate and positioning the filter plate on the support body to maintain the stability of the filtration state.

[0028] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] like Figures 1 to 5 As shown, in one embodiment, a sludge treatment discharge pipe filter tank includes a filter tank body 1, with an inlet pipe 2 and an outlet pipe 3 respectively connected to both sides of the filter tank body 1. A filter assembly is disposed inside the filter tank body 1, and the filter assembly includes:

[0030] The filter plate 4 includes an inclined filter plate 401 and a horizontal filter plate 402. The filter plate 4 divides the filter tank 1 into a first cavity 101 and a second cavity 102. The first cavity 101 is connected to the mud inlet pipe 2, and the second cavity 102 is connected to the mud outlet pipe 3.

[0031] Specifically, filter holes are provided on the surfaces of both the inclined filter plate 401 and the horizontal filter plate 402.

[0032] It should be understood that there are two booster pump pipelines in the sludge treatment of the water plant. One is the pipeline for discharging sludge from the high-density tank to the equalization tank, and the other is the pipeline for feeding sludge from the equalization tank to the centrifuge. By installing the filter tank 1 on the high-density tank sludge discharge pipeline, both the high-density tank sludge discharge pump and the centrifuge sludge inlet pump are protected.

[0033] During the filtration process, the muddy water enters the first chamber 101 of the filter tank 1 through the mud inlet pipe 2, and then enters the second chamber 102 after being filtered by the filter plate 4. The muddy water in the second chamber 102 is discharged through the mud outlet pipe 3 and then enters the lifting pump, which prevents impurities in the muddy water from entering the lifting pump, thus helping to protect the lifting pump.

[0034] By dividing the filter plate 4 into an inclined filter plate 401 and a horizontal filter plate 402, in order to intercept impurities, when the water flows on the inclined filter plate 401, the water flow is in a laminar state due to the small hydraulic radius, which is conducive to sedimentation. The inclined filter plate 401 increases the settling area of ​​the particles, accelerates the settling speed of the particles, and increases the difficulty of impurities remaining on the filter plate, so as not to affect the flow rate.

[0035] like Figure 1 and Figure 2 As shown, in one embodiment, the top of the filter tank 1 is covered with a sealing cover 5, and the top of the sealing cover 5 is fixedly connected to an exhaust pipe 6, on which an exhaust valve 7 is installed; the bottom of the filter tank 1 is fixedly connected to a vent pipe 8, on which a vent valve 9 is installed. It should be understood that during the high-density tank water filling operation, the exhaust valve 7 is opened, and after the filter tank 1 is filled with water, the exhaust valve 7 is closed, and the filter tank 1 is officially put into operation. By installing the vent valve 9 and the vent pipe 8, when the vent valve 9 is opened, the muddy water in the first chamber 101 can be discharged into the mud discharge ditch.

[0036] like Figure 2 and 3As shown, in one embodiment, a support body 10 is provided inside the filter tank 1. The support body 10 includes an arc-shaped support 1001 and an inclined support 1002, both of which are fixedly connected to the inner wall of the filter tank 1. It should be understood that by providing the arc-shaped support 1001 and the inclined support 1002, the structure of the inclined filter plate 4 and the horizontal filter plate 4 can be adapted to better support and limit the filter plate 4.

[0037] like Figure 2 and Figure 5 As shown, in one embodiment, a support frame 11 is fixedly connected to the edge of the filter plate 4. The support frame 11 includes an arc-shaped frame 1101 and an inclined frame 1102. A first support rod 12 and a second support rod 13 are respectively contacted on the surfaces of the arc-shaped frame 1101 and the inclined frame 1102. A lower pressure plate 14 is fixedly connected between the tops of the first support rod 12 and the second support rod 13, and the lower pressure plate 14 contacts the bottom of the sealing cover 5. It should be understood that the arc-shaped frame 1101 and the inclined frame 1102 are used to adapt to the shape of the filter plate 4 and to cooperate and overlap with the arc-shaped support 1001 and the inclined support 1002.

[0038] Furthermore, after the lower pressure plate 14 is pressed against the sealing cover 5, the lower pressure plate 14 will press against the support frame 11 through the first support rod 12 and the second support rod 13, thereby pressing the filter plate 4, and thus positioning the filter plate 4 on the support body 10 to maintain the stability of the filtration state.

[0039] like Figure 1 As shown, in one embodiment, a connecting ring 15 is fixedly connected to the surface of the filter tank 1, and the connecting ring 15 is fixedly connected to the sealing cover 5 by bolts 16. It should be understood that by setting bolts 16 to connect the sealing cover 5 and the connecting ring 15, a detachable connection is achieved.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
