Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to a squeezing device for treating sewage waste residue. Background Art

[0002] At present, when treating domestic sewage, it is generally treated in sequence through a primary anaerobic sedimentation tank, a secondary anaerobic sedimentation tank, and a clarification tank. Among them, a large amount of waste residue will be precipitated in the primary anaerobic sedimentation tank and the secondary anaerobic sedimentation tank, especially the amount of waste residue precipitated in the primary anaerobic sedimentation tank is very large. This waste residue can be prepared into fertilizer or fuel through squeezing, dehydration, and drying, which has very good economic value. For this reason, mechanical equipment for dehydrating waste residue has now appeared.

[0003] For example: the patent document with the Chinese authorization announcement number CN219256548U, and a technical solution named "a domestic sewage waste residue squeezing and drying machine" disclosed, which includes the following technical features: bottom plate, collection box, support frame, rotating shaft, squeezing cylinder, motor, bracket, water collection box, drain pipe, electric slide rail, slider, cylinder, push rod, and pressure plate. Among them, in order to squeeze out as much water as possible from the waste residue, the waste residue added to the squeezing cylinder is generally squeezed with a large pressure. In this way, after squeezing, it is easy for the waste residue to stick to the squeezing cylinder too tightly. In addition, there are multiple groups of filter holes on the squeezing cylinder, which will further limit the waste residue from being separated from the squeezing cylinder after squeezing, so that when the squeezing cylinder is turned over to dump the waste residue, there is too much waste residue that cannot be poured out normally, which requires workers to clean up the waste residue that has not been poured out, which not only leads to low squeezing efficiency, but also easily leads to high labor intensity for workers. In addition, during the overturning and dumping process of the pressing cylinder, the waste residue rolls and falls into the collection box, which easily causes the waste residue to break into powder, which is not convenient for use as fuel.

[0004] Therefore, it is very necessary to design a squeezing device for treating sewage and waste residue to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of the utility model is to solve the above-mentioned problems and shortcomings and to provide a squeezing device for treating sewage waste residue, which can facilitate the rapid and accurate discharge of the squeezed waste residue without the intervention of workers, which can not only improve the squeezing efficiency of the sewage waste residue, but also help to reduce the labor intensity of workers; and the squeezed waste residue can be output in blocks, which can be conveniently used as fuel.

[0022] like Figure 1 As shown, a squeezing device for treating sewage and waste residue described in the utility model comprises a squeezing box 1, a limiting baffle mechanism 2, a pushing baffle mechanism 3, and a squeezing mechanism 4, wherein a holding chamber 11 is provided on the squeezing box 1, a cavity bottom of the holding chamber 11 is provided with a water filtering mesh plate 12 for filtering sewage, a slag discharge hole 13 and a mounting hole 14 which penetrate to the outside of the squeezing box 1 are respectively provided on the left and right lower cavity walls of the holding chamber 11, the limiting baffle mechanism 2 can be opened and closed on the slag discharge hole 13, the pushing baffle mechanism 3 is provided on the mounting hole 14, and the movable end of the pushing baffle mechanism 3 can reciprocate to push the slag toward the slag discharge hole 13, the squeezing mechanism 4 is provided above the holding chamber 11, and the movable end of the squeezing mechanism 4 can reciprocate to press the water filtering mesh plate 12, and the squeezing mechanism 4, the limiting baffle mechanism 2, the pushing baffle mechanism 3, the water filtering mesh plate 12 and the inner wall of the holding chamber 11 together enclose a slag pressing space 10.

[0023] In the squeezing device, after the squeezing mechanism 4 has finished squeezing the waste residue, the slag outlet 13 can be opened by the limit baffle mechanism 2, and then the squeezing waste residue can be quickly, accurately and comprehensively pushed out by the push baffle mechanism 3, which can effectively reduce the residual amount of waste residue in the slag pressing space 10, without the need for workers to clean it up, which can not only improve the slag pressing efficiency of sewage waste residue, but also help reduce the labor intensity of workers. And by pushing the squeezing waste residue out by the push baffle mechanism 3, the pushed waste residue can be output in blocks, thereby preventing the squeezing waste residue from being too loose, which can be conveniently used as fuel.

[0024] The water filter screen 12 includes an outer frame, a plurality of nylon meshes, and a plurality of stainless steel meshes. Each nylon mesh and each stainless steel mesh are stacked one by one, and the outer frame clamps the outer edges of each nylon mesh and each stainless steel mesh. Such a water filter screen 12 not only has a good water filtering effect, but also has a high structural strength, so it can meet the needs of squeezing very well. Figure 1 As shown, the bottom of the containing cavity 11 is provided with an embedding hole 15 that penetrates to the bottom of the pressing box 1, and the embedding hole 15 matches the water filter screen 12. The water filter screen 12 is horizontally embedded in the embedding hole 15, and the top surface of the water filter screen 12 is flush with the bottom of the containing cavity 11. The outer frame of the water filter screen 12 is provided with a plurality of fixing lugs 121, and each fixing lug 121 is placed on the bottom surface of the pressing box 1, and each fixing lug 121 is fixed to the pressing box 1 with screws (not shown in the figure). This can meet the requirement of stable installation of the water filter screen 12, and thus can meet the requirements of actual use.

[0025] like Figure 1 As shown, a guide inclined plate 16 with a lower left side and a higher right side is provided on the lower opening edge of the outer side of the slag discharge hole 13. The guide inclined plate 16 can conveniently and stably guide the waste slag downward, thereby facilitating the improvement of the accuracy and stability of the waste slag output, and further contributing to further improving the applicability of the pressing device.

[0026] like Figure 1 As shown, in actual use, the lower end of the guide inclined plate 16 is directly placed above the conveyor belt 20, so that it is easy to stably receive the waste slag and accurately and stably transport the waste slag to the required area, which helps to improve the convenience of production.

[0027] like Figure 1 and Figure 2As shown, a water-blocking groove 161 is provided on the upper surface of the guide inclined plate 16 and runs through in the longitudinal direction (the longitudinal direction is the front-to-back direction), and at least one drainage hole 162 is provided at the bottom of the water-blocking groove 16 and runs through the guide inclined plate 16 vertically. In this way, when waste water is accidentally discharged between the limit baffle mechanism 2 and the slag discharge hole 13, the water-blocking groove 161 can prevent the waste water from flowing along the guide inclined plate 16 to the conveyor belt 20; and the drainage hole 162 can also be used to quickly drain the waste water in the water-blocking groove 161 to avoid waste water accumulation and overflow.

[0028] like Figure 1 and Figure 2 As shown, the lower opening of the drainage hole 162 is located on the convex pipe 163, which can prevent the sewage from flowing along the lower surface of the guide inclined plate 16, thereby better preventing the sewage from flowing turbulently.

[0029] like Figure 1 As shown, a water receiving tank body 5 is provided below the water filter screen plate 12. This can facilitate the collection of squeezed waste water, thereby helping to improve the convenience of collection.

[0030] like Figure 1 and Figure 4 As shown, the water receiving tank body 5 is also located directly below the drainage hole 162 and the mounting hole 14. In this way, the water receiving tank body 5 can be used to receive waste water discharged from the drainage hole 162. When waste water is accidentally discharged between the push baffle mechanism 3 and the mounting hole 14, the water receiving tank body 5 can be used to receive it, thereby preventing waste water from being discharged at will.

[0031] like Figure 1 As shown, the position-limiting baffle mechanism 2 includes a first transverse cylinder 21 and a first vertical baffle 22 matching the slag discharge hole 13. The first transverse cylinder 21 is arranged on the left side of the press box 1, and the first vertical baffle 22 is arranged in the slag discharge hole 13, and the first vertical baffle 22 is drivingly connected to the first transverse cylinder 21. Such a position-limiting baffle mechanism 2 is very simple and reliable, which is not only convenient to manufacture, but also can play a stable and effective blocking role, so that the pressing process can be carried out very smoothly and stably.

[0032] In order to improve the sealing performance between the first vertical baffle 22 and the slag discharge hole 13, a sealing rubber ring (not shown in the figure) can be provided on the first vertical baffle 22 to press against the hole wall of the slag discharge hole 13, so that the squeezing process can be completed very stably.

[0033] like Figure 1As shown, the push baffle mechanism 3 includes a second transverse cylinder 31 and a second vertical baffle 32 matching the mounting hole 14. The second transverse cylinder 31 is arranged on the right side of the pressing box 1, and the second vertical baffle 32 is arranged in the mounting hole 14, and the second vertical baffle 32 is drivingly connected to the second transverse cylinder 31. Such a push baffle mechanism 3 is very simple and reliable, which is not only convenient for manufacturing, but also can play a stable and effective blocking and pushing role, so that the pressing and pushing process can be carried out very smoothly and stably.

[0034] In order to improve the sealing between the second vertical baffle 32 and the mounting hole 14, a sealing rubber ring (not shown) can be provided on the second vertical baffle 32 to press against the hole wall of the mounting hole 14, so that the squeezing process can be completed very stably.

[0035] like Figure 1 As shown, the pressing mechanism 4 includes a vertical cylinder 41 and a horizontal pressing plate 42 matched with the containing chamber 11. The vertical cylinder 41 is arranged above the pressing box 1, and the horizontal pressing plate 42 is arranged in the containing chamber 11, and the horizontal pressing plate 42 is driven and connected to the vertical cylinder 41. Such a pressing mechanism 4 is very simple and reliable, which is not only convenient for manufacturing, but also can play a stable and effective pressing role, so that the pressing process can be carried out very smoothly and stably.

[0036] In order to improve the sealing between the horizontal pressing plate 42 and the containing chamber 11, a sealing rubber ring (not shown in the figure) can be provided on the horizontal pressing plate 42 to press against the wall of the containing chamber 11, so that the squeezing process can be completed very stably.

[0037] like Figure 1 As shown, the squeezing device for treating wastewater residue further includes a delivery pipe 6, a delivery pump 7, and a containing tank 8. The edge of the upper cavity opening of the containing cavity 11 is tilted outward to form a feed nozzle 111. The two ends of the delivery pipe 6 are respectively placed in the feed nozzle 111 and the containing tank 8. The delivery pump 7 is connected in series to the delivery pipe 6. The containing tank 8 can be used to contain the collected waste residue with sewage, so that the delivery pipe 6 and the delivery pump 7 can be used to stably add waste residue to the containing tank 8, thereby helping to further improve the convenience and efficiency of squeezing.

[0038] like Figure 1 As shown, the horizontal pressing plate 42 can move upward to a position higher than the lower end of the feed nozzle 111, so as to avoid the horizontal pressing plate 42 affecting the input of waste residue; and the feed nozzle 111 can stably guide the waste residue into the containing cavity 11.

[0039] like Figure 1As shown, a stirring mechanism 9 is provided in the holding tank 8. The stirring mechanism 9 can prevent the waste residue from settling and solidifying at the bottom of the holding tank 8, which can avoid affecting the extraction of the delivery pump 7, thereby making the addition of the waste residue more stable and reducing the probability of failure of the delivery pump 7.

[0040] like Figures 3 to 5 As shown, when in use, firstly, a suitable amount of waste residue is pumped out from the storage tank 8 by the delivery pump 7 and pumped into the storage chamber 11; then, the squeezing mechanism 4 is pressed down to dehydrate the waste residue, and the squeezing sewage will flow into the water receiving tank body 5; after squeezing is completed, the horizontal pressing plate 42 of the squeezing mechanism 4 moves upward, and the first vertical baffle 22 of the limit baffle mechanism 2 moves to the left; after the horizontal pressing plate 42 and the first vertical baffle 22 move to the appropriate position, the second vertical baffle 32 of the push baffle mechanism 3 moves to the right to push the squeezing waste residue to slide through the slag discharge hole 13 onto the guide inclined plate 16; then, the waste residue can be guided to the conveying belt 20 through the guide inclined plate 16; then, the push baffle mechanism 3 and the limit baffle mechanism 2 are reset; this can complete a squeezing process. By repeating this process, the demand for squeezing waste residue can be continuously met. Such a pressing device can help to quickly and accurately discharge the waste residue after pressing without the need for worker intervention, which can not only improve the squeezing efficiency of sewage waste residue, but also help to reduce the labor intensity of workers.
