[0028] A sludge resource utilization device, such as Figures 1 to 3As shown, the device includes an outer shell 1 supported by a support frame on the ground. Inside the outer shell 1, there is a reaction chamber 2 and a dehydration chamber 3. The reaction chamber 2 is located above the dehydration chamber 3, and the bottom of the reaction chamber 2 has a communication port that communicates with the dehydration chamber 3. A sealing component is provided on the side wall of the communication port. A discharge port is provided on one side of the dehydration chamber 3. A filter plate 8 is detachably fixed to the inner wall of the dehydration chamber 3. A drain pipe is provided on one side below the filter plate 8. A telescopic rod 6 is installed on the outer wall of the outer shell 1. The telescopic rod 6 passes through the outer shell 1 and is connected to a pressure plate 7. The pressure plate 7 slides in cooperation with the top outer wall of the filter plate 8 and the inner wall of the dehydration chamber 3. A telescopic rod 9 is installed on the side wall of the outer shell 1. The telescopic end of the telescopic rod 9 is connected to a sealing plate 10 through a connecting frame. The sealing plate 10 is located at the communication point between the dehydration chamber 3 and the discharge port. A sealing gasket is provided on the side wall of the sealing plate 10 that cooperates with the inner wall of the dehydration chamber 3 and the top outer wall of the filter plate 8.

[0029] The top of the outer shell 1 is provided with a feeding port, and a stirring motor 5 is installed on the outer wall of the top of the outer shell 1. The output shaft of the stirring motor 5 is fixedly connected to a stirring rod 4 located in the reaction chamber 2. A scraper is connected to the side wall of the central shaft of the stirring rod 4 and it contacts and cooperates with the inner wall of the reaction chamber 2.

[0030] The closing assembly includes baffles 11 and guide grooves 13. Two guide grooves 13 are opened opposite each other on the side wall of the communication opening. The baffles 11 are slidably fitted on the inner wall of the guide grooves 13. The two baffles 11 are used to close the communication opening. The side walls of the two guide grooves 13 are connected to the same sliding groove opened on the outer shell 1. A rack 14 is fixedly connected to the side wall of each of the two baffles 11. The rack 14 is slidably connected to the inner wall of the sliding groove. The two racks 14 are arranged alternately. The two racks 14 are engaged with the same gear 15 set in the sliding groove. A telescopic rod 12 is installed on one side of one of the guide grooves 13. The telescopic end of the telescopic rod 12 is fixedly connected to the side wall of one of the guide grooves 13.

[0031] The outer casing 1 contains a control module, which is a mature existing technology and will not be described in detail here. The stirring motor 5, telescopic rod 6, telescopic rod 9 and telescopic rod 12 are all electrically connected to the control module.

[0032] During operation, sludge enters reaction chamber 2 through the feed inlet, and reactants are added to the reaction chamber 2. The stirring motor 5 drives the stirring rod 4 to rotate, ensuring thorough mixing of the reactants and sludge. A scraper removes sludge adhering to the inner wall of reaction chamber 2. During this process, baffle 11 seals the connecting port. After mixing, the telescopic rod 12 moves a guide groove 13 away from the centerline of the connecting port. A rack 14 moves synchronously with the guide groove 13, and a gear 15 rotates with the rack 14, driving another rack 14 to move synchronously in the opposite direction, thus driving another... The guide groove 13 moves, connecting the reaction chamber 2 and the dewatering chamber 3. The sludge falls into the dewatering chamber 3 through the connecting port. The telescopic rod 12 pushes the baffle 11 to reset and close the connecting port. Then, the telescopic rod 6 and the telescopic rod 9 drive the pressure plate 7 and the sealing plate 10 to move in opposite directions, squeezing and dewatering the sludge in the dewatering chamber 3. The water is drained from the drain pipe through the filter plate 8. Then, the telescopic rod 9 drives the sealing plate 10 to move in the opposite direction until the dewatering chamber 3 is connected to the discharge port. Then, the telescopic rod 6 pushes the pressure plate 7 to move, pushing the sludge to the discharge port for further treatment.

[0033] By incorporating a telescopic rod 6, a pressure plate 7, a telescopic rod 9, and a sealing plate 10, the dewatering chamber 3 is sealed off from the discharge port during extrusion dewatering, preventing sludge from being discharged from the discharge port during extrusion and avoiding insufficient dewatering of sludge that could affect subsequent steps. At the same time, the pressure plate 7 can be used to extrude sludge or push it out of the dewatering chamber 3, reducing the structural requirements.

[0034] By incorporating a rack 14 and a gear 15, the two baffles 11 can move synchronously under the drive of a telescopic rod 12, reducing the need for a power source.

[0035] Example 2

[0036] A sludge resource utilization device, this embodiment is based on embodiment 1, with the following improvements, such as... Figure 1 , Figure 4 As shown, a reagent box 16 is provided on the top of the outer shell 1, and a rotating cavity communicating with the reaction chamber 2 is provided at the bottom of the reagent box 16. A rotating wheel 17 is rotatably connected to the inner wall of the rotating cavity.

A plurality of circumferentially arranged receiving grooves 18 are provided on the outer wall of the rotating wheel 17.

[0037] After the sludge is put into the reaction chamber 2, the drive mechanism drives the rotating wheel 17 to rotate, and a fixed amount of reactant enters the receiving tank 18 and moves with the receiving tank 18. When the receiving tank 18 moves into the reaction chamber 2, the reactant in the receiving tank 18 falls into the reaction chamber 2, realizing the automatic addition of reactant.

[0038] The system is equipped with a reagent tank 16, a rotating wheel 17, and a receiving tank 18, which enables automatic addition of the reactant, eliminating the need for manual addition of the reactant after each sludge input.

[0039] Working principle: During operation, sludge enters the reaction chamber 2 through the feeding port. The drive mechanism drives the rotating wheel 17 to rotate, and a fixed amount of reactant enters the receiving tank 18 and moves with it. When the receiving tank 18 moves into the reaction chamber 2, the reactant in the receiving tank 18 falls into the reaction chamber 2. The stirring motor 5 drives the stirring rod 4 to rotate, so that the reactant and sludge are fully mixed. The scraper can scrape off the sludge adhering to the inner wall of the reaction chamber 2. During this process, the baffle 11 closes the connecting port. After mixing is completed, the telescopic rod 12 drives a guide groove 13 to move away from the centerline of the connecting port. A rack 14 moves synchronously with the guide groove 13. As rack 14 rotates, it drives another rack 14 to move synchronously in the opposite direction, which in turn moves another guide groove 13, connecting reaction chamber 2 with dewatering chamber 3. Sludge falls into dewatering chamber 3 through the connecting port. Telescopic rod 3 12 pushes baffle 11 to reset and close the connecting port. Then telescopic rod 1 6 and telescopic rod 2 9 drive pressure plate 7 and closing plate 10 to move in opposite directions, squeezing and dewatering the sludge in dewatering chamber 3. Water is drained from the drain pipe through filter plate 8. Then telescopic rod 2 9 drives closing plate 10 to move in the opposite direction until dewatering chamber 3 is connected to discharge port. Then telescopic rod 1 6 pushes pressure plate 7 to move, pushing sludge to discharge port for further treatment.
