Description

Technical Field

[0001] This utility model relates to the field of sludge dewatering technology, and in particular to a device for homogenizing and dewatering dry and wet sludge. Background Technology

[0002] Sludge dewatering is a sludge treatment method that removes water from fluid raw, concentrated, or digested sludge and transforms it into semi-solid or solid sludge blocks. After dewatering, the sludge moisture content can be reduced to 55% to 80%, depending on the properties of the sludge and sediment and the efficiency of the dewatering equipment. Workers often use dewatering devices when mixing dry and wet sludge for dewatering.

[0003] According to the search, the Chinese patent "A Dry and Wet Sludge Mixing, Homogenizing and Dewatering Device" authorized announcement number "CN220723925U" includes a box body with a through hole on the top of the back of the box body; an extrusion mechanism, which is located inside the box body and includes a pressure plate body; and a pushing mechanism, which is located inside the box body. In this invention, by setting up scrapers, round blocks, a first cylinder, and an inclined rod, the first cylinder can be activated to push the push-pull block upward, thereby driving the inclined rod upward. The inner wall of the inclined rod will squeeze the outer surface of the round block, so that the two round blocks drive the two scrapers to move towards each other, scraping off the sludge adhering to the bottom of the pressure plate body. This achieves the effect of facilitating the cleaning of sludge adhering to the bottom of the pressure plate body, thus avoiding a decrease in sludge recovery rate. However, the above method has the following defects in actual use: during the relative movement of the scrapers, although the sludge can be squeezed and scraped off, a small amount of sludge is easily squeezed and flows along the through hole to the outside of the box. Moreover, the scraping method of resistance can easily leave a thin layer of sludge residue, and sludge is also easy to adhere to the scrapers, resulting in a decrease in sludge recovery rate. In addition, the design of the through hole and the open feeding port can easily cause odor to be emitted during the dewatering process, affecting the working environment. Utility Model Content

[0004] Therefore, it is necessary to provide a dry and wet sludge mixing, homogenization and dewatering device to address the problems of reduced sludge recovery rate and odor emission affecting the working environment.

[0005] A dry and wet sludge mixing, homogenization, and dewatering device includes a housing and a filter plate and a pressure plate disposed therein; it also includes two cleaning mechanisms, which are disposed inside the housing and used to clean the sludge remaining on the pressure plate; wherein, the cleaning mechanism includes a U-shaped tube and two strip grooves, the strip grooves being opened on the U-shaped tube, the horizontal position of the strip grooves being lower than the horizontal position of the pressure plate, and the angles between the two strip grooves and the horizontal plane being 30 degrees and 80 degrees, respectively.

[0006] In one embodiment, a three-way flexible tube extending to the outside of the housing is provided between the two loops, and an air pump is provided on the top of the housing, with the output end of the air pump connected to one end of the three-way flexible tube.

[0007] In one embodiment, two threaded plates are provided on the outer side of the U-shaped tube, and a servo motor is provided on the outer side of the housing. The output shaft of the servo motor is equipped with a lead screw through a coupling, and one end of the lead screw passes through and is threaded to the outer side of the two threaded plates in sequence.

[0008] In one embodiment, the interior of the housing is provided with a push plate above the pressure plate, and the exterior of the housing is provided with two cylinders, which are used to drive the pressure plate and the push plate respectively.

[0009] In one embodiment, grooves are provided on both sides of the interior of the box, and the U-shaped tube is located inside the grooves.

[0010] In one embodiment, the input end of the air pump is equipped with a bend tube, one end of which extends into the interior of the housing and is located below the filter plate.

[0011] In one embodiment, a discharge port is provided on one side of the box, and a cover plate is provided on the outside of the discharge port. Beneficial effects

[0012] 1. By setting up a U-shaped tube and two strip grooves at different angles, the U-shaped tube drives the strip grooves to move gradually along the bottom of the pressure plate. During the movement, the gas sprayed from the strip grooves forms an air blade to clean the sludge under the pressure plate, which has a good cleaning effect and improves the sludge recovery rate.

[0013] 2. The use of a cover and closing plate ensures a closed dehydration process inside the chamber. Combined with an air pump and folding pipes, the gas in the working area is circulated, reducing odor emissions and ensuring a safe working environment. Attached Figure Description

The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0026] The following is combined with Figures 1-4 This invention describes a dry and wet sludge mixing, homogenization, and dewatering device.

[0027] In one embodiment, a dry and wet sludge mixing, homogenizing, and dewatering device includes a housing 100 and filter plates 200 and pressure plates 300 disposed therein; it also includes two cleaning mechanisms 400, which are disposed inside the housing 100 and used to clean the sludge remaining on the pressure plates 300; wherein, the cleaning mechanism 400 includes a U-shaped tube 410 and two strip grooves 420, the strip grooves 420 being opened onto the U-shaped tube 410, the horizontal position of the strip grooves 420 being lower than the horizontal position of the pressure plates 300, and the angles between the two strip grooves 420 and the horizontal plane being 30 degrees and 80 degrees, respectively.

[0028] like Figure 1 and Figure 2 As shown, a three-way flexible hose 411 extending to the outside of the box 100 is provided between the two loop tubes 410. An air pump 110 is provided on the top of the box 100, and the output end of the air pump 110 is connected to one end of the three-way flexible hose 411.

[0029] In this embodiment, when cleaning the sludge remaining on the pressure plate 300, the two loop tubes 410 are driven to move relative to each other, and the air pump 110 is started at the same time. The air can be introduced into the loop tubes 410 along the three-way hose 411. Then, during the movement of the loop tubes 410, the strip grooves 420 at a 30-degree angle to the horizontal plane will pre-discharge the air below the pressure plate 300 to form an air blade. During the discharge of the small-angle air blade, there is good shearing force, which can peel off the sludge with high adhesion. Then, the strip grooves 420 at an 80-degree angle to the horizontal plane will exhaust air again. The exhaust direction is close to perpendicular to the bottom of the pressure plate 300, which can increase the impact force and reduce the phenomenon of thin sludge residue. After the pressure plate 300 is cleaned, the loop tubes 410 can be driven to reset.

[0030] It should be noted that the output power and specifications of the air pump 110 can be selected according to the condition of the sludge to be dewatered, and the number of cleaning cycles of the loop tube 410 can be adjusted according to the viscosity of the sludge to ensure that the cleaning requirements are met.

[0031] Feed ports are provided on both sides of the box 100, and a closing plate is provided on the outside of the feed ports. A drain pipe is also provided on the box 100.

[0032] like Figure 2 As shown, two threaded plates are provided on the outer side of the U-shaped tube 410, and a servo motor is provided on the outer side of the housing 100. The output shaft of the servo motor is equipped with a lead screw 120 through a coupling. One end of the lead screw 120 passes through and is threaded to the outer side of the two threaded plates in sequence.

[0033] Starting the servo motor will cause the lead screw 120 to drive the corresponding threaded plate to move, thereby causing the two loop tubes 410 to move relative to each other and away from each other, gradually cleaning the sludge under the pressure plate 300.

[0034] It should be noted that upright plates are also provided on the two loop tubes 410. The two upright plates are installed inside the housing 100, and a limit rod is provided between the two upright plates to reduce the accidental displacement or rotation of the loop tubes 410 during movement.

[0035] like Figure 1 , Figure 2 and Figure 4 As shown, the box 100 has a push plate 130 located above the pressure plate 300 inside, and two cylinders are provided on the outside of the box 100. The two cylinders are used to drive the pressure plate 300 and the push plate 130 respectively.

[0036] One cylinder drives the pressure plate 300 to complete the squeezing and dewatering operation. The remaining cylinder can drive the push plate 130 after dewatering to discharge the dewatered sludge to the outside of the box 100.

[0037] like Figure 2 As shown, grooves are provided on both sides inside the box 100, and the U-shaped tube 410 is located inside the groove.

[0038] The U-shaped tube 410 is housed in a groove, so that it is not easily obstructed when the pressure plate 300 is dewatering.

[0039] like Figure 1 and Figure 2 As shown, the input end of the air pump 110 is equipped with a folded pipe, one end of which penetrates into the interior of the housing 100 and is located below the filter plate 200.

[0040] The gas inside the box 100 is extracted by using a folding pipe, and then discharged along the three-way flexible hose 411 for gas recycling, ensuring the sealing effect of the work area and reducing odor emission;

[0041] It should be noted that users can install an activated carbon box in the middle of the tube for odor adsorption.

[0042] like Figure 1 As shown, a discharge port is provided on one side of the box 100, and a cover plate is provided on the outside of the discharge port.

[0043] When the pusher plate 130 pushes the material, the user can open the cover plate on the discharge port in advance, and then discharge the dewatered sludge along the discharge port.

[0044] Working principle: The user can feed the sludge into the box 100 through the feeding port. Then, the pressure plate 300 and filter plate 200 are used to squeeze and dewater the sludge. After dewatering, the servo motor is started to make the two U-shaped tubes 410 move relative to each other. During the movement, the gas sprayed from the strip groove 420 forms an air blade to clean the sludge remaining under the pressure plate 300. After cleaning, the push plate 130 is used to discharge the sludge through the discharge port to the outside of the box 100. Then, the water in the box 100 is discharged through the drain pipe.

[0045] It should be noted that the servo motor, air pump 110, cylinder, etc. mentioned above are all components with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the servo motor, air pump 110, and cylinder can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
