Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, specifically to an integrated device for efficient and deep sludge treatment. Background Technology

[0002] Existing sludge treatment methods include composting, incineration, and landfill. Composting is time-consuming, requires a huge area, and necessitates significant investment to prevent foul odor pollution. Sludge incineration is expensive, placing a heavy economic burden on the system. Currently, when large amounts of dredged sludge, sewage sludge, and various types of residual soil are landfilled, they contain a large amount of harmful substances. Direct landfilling will cause secondary environmental pollution to the soil and water environment, posing certain environmental risks.

[0003] When dewatering sludge, sludge treatment equipment generally uses screw press dewatering machines or high-pressure filter presses. Existing screw press dewatering machines squeeze the sludge through the screw shaft during dewatering, thereby squeezing out the water in the sludge and achieving the dewatering effect. However, the sludge near the screw shaft is far from the outlet, which can easily lead to poor dewatering effect.

[0004] Based on this, we now offer an integrated device for high-efficiency deep treatment of sludge, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] The purpose of this invention is to provide an integrated device for efficient and deep treatment of sludge, so as to solve the problems in the background art.

At the same time, the odor in the sludge is treated by the gas treatment component 800.

[0025] In one embodiment, such as Figure 1 and Figure 2 As shown, the pretreatment mechanism 100 has a first support column 101 at its lower end, a first feed inlet 102 on one side, a first discharge outlet 103 at its lower end, a weighing sensor 104 at the bottom, and a pH meter 105 on one side. In use, the amount of sludge to be treated in the pretreatment mechanism 100 is weighed through the weighing sensor 104, and the pH value of the sludge is detected through the pH meter.

[0026] In one embodiment, such as Figure 1 and Figure 2As shown, the pretreatment unit 100 is equipped with multiple screw-type quantitative feeders 400 at its top. The pretreatment unit 100 is also equipped with a stirrer 500. Both the screw-type quantitative feeders 400 and the stirrer 500 are common and readily available devices on the market. In use, based on the amount of sludge to be treated weighed by the weighing sensor 104 and the pH value detected by the pH meter, the system calculates and controls the screw-type quantitative feeders 400 to add a quantitative amount of treatment additives into the pretreatment unit 100. The stirrer 500 is used to stir the sludge and additives to ensure that they are fully mixed and reacted.

[0027] In one embodiment, such as Figure 3 As shown, the dewatering mechanism 200 includes a cylinder 201. One end of the cylinder 201 is provided with a second feed inlet 202, and the other end of the cylinder 201 is provided with a second discharge outlet 203. The second feed inlet 202 is connected to the first discharge outlet 103 through a connecting pipe 300. The lower end of the cylinder 201 is provided with a second support column 204. In use, the sludge treated by the pretreatment mechanism 100 is transported from the second feed inlet 202 into the cylinder 201 through the connecting pipe 300 for further processing.

[0028] In one embodiment, such as Figure 3 As shown, a screw extrusion conveying assembly is provided inside the cylinder 201. The screw extrusion conveying assembly includes a motor 205 located at one end of the cylinder 201. The output end of the motor 205 is connected to a rotating shaft 206. An expansion part 207 is provided on the rotating shaft 206. A spiral blade 208 is provided on the outside of the rotating shaft 206. In use, the rotating shaft 206 and the spiral blade 208 are driven to rotate together by the motor 205, thereby conveying and extruding the sludge inside the cylinder 201.

[0029] In one embodiment, such as Figure 3 As shown, the heating assembly 600 includes a fixed sleeve 601 sleeved on the outside of the cylinder 201. The fixed sleeve 601 is provided with a heating tube 602. In use, the sludge is heated by the heating tube 602, so that the moisture and gas in the sludge are in an unstable state.

[0030] In one embodiment, such as Figure 3 As shown, the negative pressure dewatering assembly 700 includes a water filter hole 701 located on the lower side of the cylinder 201. The water filter hole 701 is located below the expansion section 207. A first fixed box 702 is provided on the outside of the water filter hole 701. One side of the first fixed box 702 is connected to the negative pressure pump 703 through a pipe. In use, when the sludge passes through the water filter hole 701 with the spiral blade, the sludge is squeezed by the expansion section 207. At the same time, the negative pressure generated by the negative pressure pump 703 in the first fixed box 702 draws the water in the sludge into the first fixed box 702 through the water filter hole 701.

[0031] In one embodiment, such as Figure 3As shown, the gas treatment assembly 800 includes an air outlet 801 located on the upper side of the cylinder 201, above the expansion section 207.

An air outlet 806 is provided above the activated carbon adsorption plates 805. In use, when the sludge passes through the air outlet 801 with the spiral blades, the sludge is squeezed by the expansion section 207. At the same time, the odor emitted from the sludge is drawn into the second fixed box 802 through the air outlet 801 by the fan 803, and the odor is discharged from the air outlet 806 after being adsorbed by the activated carbon adsorption plates 805.

[0032] The above embodiment discloses an integrated device for high-efficiency deep treatment of sludge. In use, sludge is first added to the pretreatment unit 100 through the first inlet 102. The amount of sludge to be treated in the pretreatment unit 100 is weighed by a weighing sensor 104, and the pH value of the sludge is detected by a pH meter. Then, after system calculation, a screw-type quantitative feeder 400 is controlled to add a quantitative amount of treatment additive to the pretreatment unit 100, and the mixture is stirred by a stirrer 500 to ensure thorough mixing and reaction of the sludge and additive. The reacted sludge is then transported to the cylinder 201 through the connecting pipe 300 from the second inlet 202. The rotating shaft 206 and the spiral blade 208 are driven by the motor 205 to rotate together, thereby conveying and compressing the sludge in the cylinder 201. When the sludge passes through the water filter hole 701 and the air outlet 801 with the spiral blade, the sludge is compressed by the expansion part 207. The negative pressure generated in the first fixed box 702 by the negative pressure pump 703 draws the water in the sludge into the first fixed box 702 through the water filter hole 701. At the same time, the odor emitted from the sludge is drawn into the second fixed box 802 through the air outlet 801 by the fan 803, and the odor is discharged from the air outlet 806 after being adsorbed by the activated carbon adsorption plate 805.
