Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, and in particular to a high-pressure dehydration vacuum suction filter. Background Technology

[0002] Wastewater treatment plant sludge differs from conventional sludge and river sludge. Its main characteristics are high water content (up to 80% or more), high organic matter content, easy decomposition and foul odor, and fine particle size. It is a viscous substance between liquid and solid, which can be transported by pumps, but is difficult to separate into solid and liquid phases through sedimentation. Sludge dewatering and drying is the most crucial step and a fundamental requirement in sludge treatment and disposal, and has become an essential link and foundation for sludge treatment and disposal.

[0003] The pain points of existing mechanical sludge dewatering technologies:

[0004] 1. Commonly used sludge dewatering equipment, without the addition of chemicals, generally results in a sludge moisture content of around 80% after treatment, which is incomplete dewatering and makes subsequent disposal more difficult;

[0005] 2. To enhance dewatering, auxiliary chemical agents such as lime, iron salts, aluminum salts, and PAM are needed. While these chemical additives can improve sludge dewatering, they also increase the amount of sludge, the workload for workers, and the cost of sludge disposal.

[0006] To address this, we designed a high-pressure resistant dewatering vacuum filtration device that can effectively improve the dewatering efficiency of sludge without increasing costs. Utility Model Content

[0007] This utility model discloses a high-pressure dehydration vacuum suction filter device, which aims to solve the problems existing in the sludge treatment devices mentioned in the background art.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A high-pressure resistant dehydration vacuum filtration device includes a treatment box, a dehydration mechanism is installed inside the treatment box, a top partition is fixedly connected to the inner wall of the treatment box, and drain pipes are fixedly embedded on both the left and right sides of the treatment box.

[0010] The dehydration mechanism includes a filter screen shell fixedly connected between the lower surface of the top partition and the bottom wall of the treatment box. A dehydration base block is provided at the bottom of the filter screen shell. A drive screw is rotatably connected at the center of the upper surface of the dehydration base block. A dehydration pressure plate is threadedly connected to the surface of the drive screw. Electric telescopic rods with corresponding positions are installed on the front and rear surfaces of the treatment box. Movable frames are fixedly connected to the telescopic ends of the two electric telescopic rods. A dehydration motor is fixedly installed on the upper surface of the movable frame.

[0011] By installing a dewatering mechanism inside the treatment box, the sludge can be squeezed in the filter screen shell by the dewatering plate and the dewatering bottom block during dewatering, and the sludge can be squeezed out of the filter screen shell and enter the treatment box. The sludge can also be squeezed into a cake shape by the dewatering plate and the dewatering bottom block.

[0012] In a preferred embodiment, the output shaft of the dehydration motor extends below the movable frame and is fixedly connected to the top of the drive screw.

[0013] In a preferred embodiment, two guide rods are fixedly connected to the upper surface of the dehydration plate, and the surface of the movable frame is provided with limiting through holes that match the guide rods. The guide rods are slidably connected to the surface of the movable frame through the limiting through holes.

[0014] By setting guide rods, the dehydration pressure plate can be guided and limited.

[0015] In a preferred embodiment, two limiting rods are fixedly connected to the lower surface of the processing box, and a sealing bottom cover is fixedly connected to the lower surface of the dehydration bottom block. L-shaped movable plates are fixedly connected to both sides of the sealing bottom cover, and the L-shaped movable plates are slidably connected to the surfaces of the limiting rods.

[0016] By setting a limit rod and an L-shaped movable plate, the dewatering bottom block can be guided and limited using the L-shaped movable plate and the limit rod.

[0017] In a preferred embodiment, the lower surface of the processing box has a discharge port located directly below the filter screen shell, and the size of the discharge port matches the dewatering bottom block.

[0018] By setting up a discharge port, an electric telescopic rod can be used to drive the dewatering block downwards to extend the discharge port, thus opening the discharge port and making it convenient for staff to clean and collect the mud cake after dewatering on the surface of the dewatering block.

[0019] In a preferred embodiment, a rubber sealing strip is fixedly connected to the upper surface of the sealing bottom cover, and an annular sealing groove is provided on the lower surface of the processing box, the size of which matches the rubber sealing strip.

[0020] By installing a rubber sealing strip, the rubber sealing strip can be inserted into the annular sealing groove when the sealing bottom cover is closed, thereby waterproofing and sealing the sealing bottom cover.

[0021] In a preferred embodiment, a control valve is fixedly installed on the surface of the drain pipe, and a vacuum pump is fixedly installed on the back of the treatment tank, with the input end of the vacuum pump extending into the interior of the treatment tank.

[0022] By installing a vacuum pump, the inside of the processing chamber can be evacuated during the dehydration and filtration process, thereby improving the dehydration and filtration effect.

[0023] In a preferred embodiment, an exhaust pipe is fixedly connected to the output end of the vacuum pump, and a pressure relief valve is provided on the surface of the exhaust pipe.

[0024] As can be seen from the above, the high-pressure dehydration vacuum suction filter provided by this utility model has the following technical effects.

[0025] Firstly, by setting up a dewatering mechanism inside the treatment tank, the sludge can be squeezed in the filter screen shell by the dewatering plate and dewatering bottom block during dewatering. The sludge is squeezed out of the filter screen shell and enters the treatment tank. The dewatering plate and dewatering bottom block can also be used to squeeze the sludge into a cake shape. Then, the electric telescopic rod can be used to drive the dewatering bottom block to extend downward to the discharge port, which makes it convenient for the staff to clean and collect the sludge cake after dewatering on the surface of the dewatering bottom block, achieving a low-cost and efficient sludge dewatering effect.

[0026] Secondly, by setting guide rods and L-shaped movable plates at the bottom of the processing box, the sealed bottom cover can be guided and limited, which facilitates the electric telescopic rod to drive the dewatering mechanism to move up and down as a whole, so as to achieve the purpose of rapid material discharge.

[0039] It should be noted that two limiting rods 209 are fixedly connected to the lower surface of the processing box 1, and a sealing bottom cover 210 is fixedly connected to the lower surface of the dehydration bottom block 202. L-shaped movable plates 211 are fixedly connected to both sides of the sealing bottom cover 210, and the L-shaped movable plates 211 are slidably connected to the surfaces of the limiting rods 209.

[0040] Reference Figure 5 The lower surface of the processing box 1 is provided with a discharge port 5, which is located directly below the filter screen shell 201, and the size of the discharge port 5 matches the dewatering bottom block 202.

[0042] By setting a sealing bottom cover 210, the discharge port 5 can be covered by the sealing bottom cover 210, and the rubber sealing strip 212 can play a certain role in waterproofing and sealing.

[0043] It should be noted that a drive screw 203 is rotatably connected to the center of the upper surface of the dewatering bottom block 202, and a dewatering pressure plate 204 is threadedly connected to the surface of the drive screw 203. Electric telescopic rods 205 with corresponding positions are installed on the front and rear surfaces of the processing box 1.
