Description

Technical Field

[0001] The utility model relates to the technical field of sludge coal blending, in particular to a sludge dehydration device for sludge coal blending. Background Art

[0002] The basic principle of sludge blending with coal is to mix sludge with coal and use it as fuel to replace pure coal in industry or energy production. Due to the high water content of sludge, the sludge is viscous and difficult to mix evenly. In order to solve this problem, the sludge is dehydrated before mixing with coal. Dehydration can reduce the moisture content of the sludge, thereby reducing its viscosity and making it easier to mix evenly with coal.

[0003] Centrifugal dehydration is often used to dehydrate sludge. This method uses a high-speed rotating centrifuge to separate water from solid sludge, so that the sludge reaches the required degree of dryness. However, although the centrifugal dehydration method has a good effect, its equipment cost is extremely high. In addition to the high initial investment, when the centrifuge fails, the subsequent maintenance cost is also high. Utility Model Content

DETAILED DESCRIPTION

[0025] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] See also Figure 1-5As shown, the utility model provides a sludge dewatering device for sludge coal blending, including a dewatering tank 1 and a dewatering assembly 4, a plurality of drainage holes 11 are opened through the surface of the dewatering tank 1, a material discharge tank 13 is fixedly connected to the left side of the dewatering tank 1, a placement rack 2 is fixedly connected to the outside of the dewatering tank 1, and the front and rear sides of the placement rack 2 are fixedly connected to an I-beam 3, and the lower surface of the I-beam 3 is fixedly connected to a plurality of supporting legs 31, and the dewatering assembly 4 includes a push plate 42, a roller 43, a pressure seat 44, and a baffle. 45 and scraper 46, the lower surface of the push plate 42 is higher than the upper surface of the dewatering tank 1, the right side of the push plate 42 is fixedly connected with a support plate 424, the upper surface of the support plate 424 is fixedly connected with two support columns 425, the upper surface of the support column 425 is fixedly connected with a fixed plate 41, the lowest point of the roller 43 is level with the upper surface of the dewatering tank 1, the outer side of the roller 43 is rotatably connected with a C-shaped buckle 431, the upper surface of the C-shaped buckle 431 is fixedly connected with a round rod 432, and the round rod 432 is fixedly connected The lower surface of the pressure seat 44 is connected to the fixed plate 41 and is located on the right side of the support column 425. The upper surface of the pressure seat 44 is fixedly connected to a sleeve 441. The inner upper end of the sleeve 441 is fixedly connected to a hydraulic rod 442. The hydraulic rod 442 is fixedly connected to the lower surface of the fixed plate 41 and is located on the right side of the round rod 432. The lower surface of the baffle 45 is flush with the upper surface of the dewatering tank 1. The upper surface of the baffle 45 is fixedly connected to a connecting frame 451. The upper surface of the connecting frame 451 is fixedly connected to the fixed plate 41. The lower surface of the scraper 46 is fitted with the inner part of the bottom wall of the dewatering trough 1, and the upper part of the scraper 46 is fixedly connected with a connecting frame 2 461, and the upper surface of the connecting frame 2 461 is fixedly connected to the lower surface of the fixed plate 41 and is located on the right side of the connecting frame 1 451. A driving member 5 for driving the dewatering assembly 4 to move is connected to the upper part of the fixed plate 41, and a water collecting trough 6 is detachably connected to the lower part of the placement rack 2, and a downpipe 62 is connected to the bottom wall of the water collecting trough 6.

[0027] When dehydrating sludge, the utility model only needs to pour the undehydrated sludge into the dehydration tank 1, and then drive the dehydration assembly 4 to move from right to left inside the dehydration tank 1 through the driving member 5, so as to complete the dehydration of the sludge in the dehydration tank 1. Finally, the sludge is discharged from the discharge tank 13 (a collection bucket or a conveyor belt can be placed under the discharge tank 13 to facilitate the subsequent treatment of the sludge). The water squeezed out of the sludge flows into the water collection tank 6 from the drain hole 11, and then discharged through the downpipe 62 (a valve can be installed at the downpipe 62, and when the valve is closed, the sewage can be temporarily stored in the water collection tank 6).

[0028] A sludge temporary storage space is formed between the scraper 46 and the baffle 45. When the scraper 46 scrapes the sludge and moves, the sludge will always be in the sludge temporary storage space. This can effectively prevent the sludge from sliding to the side of the pressure seat 44 when the scraper 46 scrapes the sludge, thereby not affecting the normal work of the pressure seat 44.

[0029] Furthermore, guard plates 12 are fixedly connected to the front and rear upper surfaces of the dewatering tank 1 ; the function of the guard plates 12 is to provide protection for the front and rear sides of the upper surface of the dewatering tank 1 to prevent the accumulated sludge from falling off.

[0030] Furthermore, the longitudinal section of the lower half of the dewatering tank 1 is trapezoidal. This trapezoidal cross-section design increases the contact area between the sludge and the dewatering tank 1, so that the sludge can be more fully in contact with the dewatering tank 1 during the dewatering process, thereby improving the dewatering efficiency and facilitating more thorough removal of moisture from the sludge, thereby obtaining a drier dewatered product.

[0031] Furthermore, the placement rack 2 includes two groups of bases 21 and multiple groups of stainless steel buckles 22. The two groups of bases 21 are respectively fixedly connected to the front and rear sides of the dewatering trough 1, and the two groups of bases 21 are connected by multiple groups of stainless steel buckles 22, and the multiple groups of stainless steel buckles 22 are evenly distributed from left to right on the lower surface of the dewatering trough 1; the main function of the placement rack 2 is to provide external support force for the dewatering trough 1, thereby reducing the possibility of deformation of the dewatering trough 1, which not only enhances the structural stability of the dewatering trough 1, but also helps to ensure that it maintains a good shape and function during use.

[0032] Furthermore, the push plate 42 is composed of an upper plate 421, an inclined plate 422 and a lower plate 423. The inclined plate 422 is fixedly connected to the lower surface of the upper plate 421, and the lower plate 423 is fixedly connected to the lower surface of the inclined plate 422. The push plate 42 structure composed of the upper plate 421, the inclined plate 422 and the lower plate 423 can reduce the reaction force generated when pushing the sludge, so that the sludge will move more smoothly during the pushing process, reducing the reaction force on the push plate 42.

[0033] Further, the driving member 5 includes multiple groups of fixed seats 51, which are equidistantly fixed on the upper surface of the base 21 located at the rear side. The upper surface of the fixed seat 51 is fixedly connected with a C-shaped seat 52, and the inner side of the C-shaped seat 52 is rotatably connected with a screw rod 53. The right end of the screw rod 53 is connected with a reduction motor 54 through a coupling. The reduction motor 54 is fixedly connected to the right side wall of the C-shaped seat 52. The outer thread sleeve of the screw rod 53 is provided with two groups of nut seats 55. The front side of the two groups of nut seats 55 is fixedly connected with an L-shaped frame 56. The lower surface of the L-shaped frame 56 is fixedly connected with a connecting plate 57. The connecting plate 57 is bolted to the upper surface of the fixed plate 41. The driving member 5 uses a reduction motor 54 to drive the screw rod 53 to rotate, thereby driving the nut seat 55 to move, and then driving the dehydration assembly 4 to move left and right (when changing the moving direction of the dehydration assembly 4, it is only necessary to change the direction of the reduction motor 54). The braking structure has high stability and can perform braking operations frequently.

[0034] Furthermore, the C-shaped seat 52 is fixedly connected to the inside with a guide rail 521, and the lower surface of the nut seat 55 is rotatably connected with a roller 551, and the roller 551 is slidably connected to the inside of the guide rail 521; when the dehydration assembly 4 moves, the nut seat 55 simultaneously drives the roller 551 to slide inside the guide rail 521, so that the dehydration assembly 4 moves more smoothly. At the same time, the mutual cooperation between the guide rail 521 and the roller 551 can also support the dehydration assembly 4, which helps to reduce the stress of the screw rod 53, thereby extending the service life of the screw rod 53.

[0035] Furthermore, the lower surface of the base 21 is fixedly connected with a chute seat 23, and the upper surface of the water collecting tank 6 is fixedly connected with a slider 61 on both the front and rear sides, and the slider 61 is slidably connected inside the chute seat 23; the sliding and detachable structure of the slider 61 and the chute seat 23 greatly facilitates the cleaning and maintenance of the water collecting tank 6. This structure allows the operator to easily remove the slider 61 from the chute seat 23 without a complicated disassembly process.

[0036] Working principle: first pour the undehydrated sludge into the dewatering tank 1, then control the reduction motor 54 to operate, the reduction motor 54 drives the screw 53 to rotate through the coupling, and at the same time, the two sets of nut seats 55 located outside the screw 53 move to the left, and the nut seat 55 drives the fixed plate 41 and the push plate 42, the roller 43, the pressure seat 44, the baffle 45 and the scraper 46 to move to the left synchronously through the L-shaped frame 56 and the connecting plate 57. During the movement of the dewatering component 4, the push plate 42 first pushes the sludge accumulated in the dewatering tank 1 to spread (the height of the spread sludge will be slightly higher than the upper surface of the dewatering tank 1). During the spreading process, part of the water in the sludge will be discharged through the drain hole 11 by itself. Then the roller 43 rolls and flattens the spread sludge, so that the sludge inside the dewatering tank 1 is flush with the upper surface of the dewatering tank 1, and part of the water in the sludge will be discharged through the drain hole 11 again under the action of the roller 43. Then the telescopic end of the hydraulic rod 442 drives the pressing seat 44 to move up and down through the sleeve 441. During this process, the pressing seat 44 exerts a vertical hammering force on the sludge, so that the water in the sludge is squeezed out. Finally, the scraper 46 scrapes up the sludge in the dewatering tank 1 and pushes it to the discharge tank 13. The water squeezed out of the sludge flows into the water collection tank 6 through the drainage hole 11 and is discharged through the downpipe 62.

[0037] It should be noted that the hydraulic rod 442 and the reduction motor 54 mentioned above can be electrically connected to the main controller to achieve automatic sludge dewatering.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
