Description

Technical Field

[0001] This utility model relates to the technical field of sludge treatment equipment, and in particular to an oily sludge drying device. Background Technology

[0002] Oilfield extraction generates large amounts of oily sludge, which significantly impacts the surrounding soil environment. According to relevant environmental laws and regulations, oily sludge generated during extraction must undergo oil displacement treatment before discharge. Therefore, the treatment of oily sludge is a crucial component of oil extraction and production. In practical applications, oily sludge drying equipment typically requires the following technologies:

[0003] 1. Feeding unit: including feed hopper, conveyor or screw feeder, etc., used to smoothly feed oily sludge into the drying device;

[0004] 2. Heating system: Common heating systems include steam heating coils, electric heating elements, or hot oil circulation systems, which provide the heat required for the drying process;

[0005] 3. Mixing mechanism: such as a mixing paddle or rake mixer, which continuously turns the sludge to ensure that the sludge is heated evenly and to speed up the drying process.

[0006] For example, a Chinese patent discloses an oily sludge drying device (patent number: CN211814109U). This device uses a combination of multiple sets of conveying screws for transmission, and the conveying screws are arranged longitudinally, which reduces the footprint. Each conveying screw is individually conveyed with hot air, which reduces heat loss. At the same time, an arc-shaped baffle is added to make the hot air delivery more targeted, thereby improving the drying rate of oily sludge.

[0007] However, during the implementation of the above technical solution, at least the following technical problems were found: as mentioned above, the device is difficult to adsorb toxic gases. When drying oil sludge, a large amount of toxic gases may be generated, such as hydrogen sulfide and ammonia. If not handled properly, it may cause environmental pollution. Utility Model Content

[0008] To address the shortcomings of existing technologies, this invention provides an oily sludge drying device, which solves the problem that the device is difficult to adsorb toxic gases. When drying oily sludge, a large amount of toxic gases, such as hydrogen sulfide and ammonia, may be generated, which may cause environmental pollution if not handled properly.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] An oily sludge drying device includes a heating tank. A stirring mechanism is installed inside the heating tank. The stirring mechanism includes a motor, a rotating shaft, a first connecting plate, a scraper, a second connecting plate, a stirring rod, a synchronous belt drive assembly, a first bevel gear shaft, a second bevel gear shaft, a connecting rod, and a fan blade. The rotating shaft is fixedly installed at the motor output end. The first connecting plate and the second connecting plate are fixedly installed inside the rotating shaft. The scraper is fixedly installed on the side wall of the first connecting plate. The stirring rod is fixedly installed on the side wall of the second connecting plate. The synchronous belt drive assembly is driven and installed on the side wall of the rotating shaft. The first bevel gear shaft is driven and installed inside the synchronous belt drive assembly. The first bevel gear shaft and the second bevel gear shaft are meshed together. The connecting rod is fixedly installed at the end of the second bevel gear shaft near the first bevel gear shaft. The fan blade is fixedly installed at the end of the second bevel gear shaft away from the connecting rod.

[0011] Preferably, a feed pipe is fixedly installed on the side wall of the heating barrel, a collection box is rotatably installed on the side wall of the connecting rod, the collection box is fixedly installed on the side wall of the heating barrel, and a connecting plate is fixedly installed inside the collection box.

[0012] Preferably, the collection box has a protective door hinged to its side wall, and a slide rail is fixedly installed inside the collection box.

[0013] Preferably, an activated carbon plate is slidably installed inside the slide rail, and a baffle is fixedly installed inside the collection box.

[0014] Preferably, a base is fixedly installed on the side wall of the heating tank, and a hydraulic component is fixedly installed inside the base.

[0015] Preferably, a fixing rod is fixedly installed on the top of the hydraulic component, a sealing plate is fixedly installed on the top of the fixing rod, a hammer is fixedly installed on the top of the sealing plate, a discharge pipe is fixedly installed on the bottom of the heating tank, and the fixing rod is slidably installed inside the discharge pipe.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. Place the sludge into the heating tank. Then, start the heating tank and motor. The motor drives the shaft to rotate counterclockwise, which in turn drives the first and second connecting discs to rotate counterclockwise. The first and second connecting discs, in turn, drive the scraper and the second connecting disc to rotate counterclockwise. The scraper scrapes the inside of the heating tank to prevent excessive sludge buildup on the inner wall. At the same time, the scraper and the second connecting discs also stir the sludge inside the heating tank to ensure uniform heating. Meanwhile, the shaft drives the synchronous belt drive assembly to rotate counterclockwise, which in turn drives the first bevel gear shaft to rotate counterclockwise. The first bevel gear shaft drives the second bevel gear shaft to rotate clockwise, which in turn drives the fan blades to rotate clockwise. The sludge is heated and produces steam and toxic gases, which are drawn into the collection box. When the steam and toxic gases pass through the activated carbon plate, they are blocked by the baffle to prevent excessive local absorption by the activated carbon plate, which would reduce its adsorption capacity. This achieves the function of recovering toxic gases and preventing air pollution.

[0018] 2. When drying is complete, start the hydraulic assembly. The hydraulic assembly drives the fixed rod to move from top to bottom, the fixed rod drives the sealing disc to move from top to bottom, and the sealing disc drives the hammer to move from top to bottom. At this time, the scraper and the second connecting disc inside the heating tank continue to rotate to prevent clumping inside. The sludge will also be exposed from inside the heating tank and will flow out along the discharge pipe. If there is a blockage, start the hydraulic assembly again. The hydraulic assembly will drive the hammer to move up and down reciprocally to ensure the smooth exposure of the sludge. Attached Figure Description

[0027] This application provides an oily sludge drying device that effectively solves the problem of the device's inability to adsorb toxic gases. During the drying of oily sludge, a large amount of toxic gases, such as hydrogen sulfide and ammonia, may be generated, potentially causing environmental pollution if not handled properly. The sludge is placed inside a heating tank. The heating tank and motor are then activated. The motor drives the rotating shaft to rotate counterclockwise, which in turn drives the first and second connecting discs to rotate counterclockwise. The first and second connecting discs, in turn, drive the scraper and the second connecting disc to rotate counterclockwise. The scraper scrapes away sludge from the inside of the heating tank, preventing excessive sludge accumulation on the inner wall. Simultaneously, the scraper and the second connecting discs also stir the sludge inside the heating tank, ensuring uniform heating. At this time, the rotating shaft drives the synchronous belt drive assembly counterclockwise, which in turn drives the first bevel gear shaft counterclockwise. The first bevel gear shaft drives the second bevel gear shaft to rotate clockwise, which in turn drives the fan blades to rotate clockwise. The sludge is heated, generating steam and toxic gases, which are drawn into the collection box. When the steam and toxic gases pass through the activated carbon plate, they are blocked by the baffle to prevent excessive local absorption by the activated carbon plate, which would reduce its adsorption capacity. This achieves the function of recovering toxic gases and preventing air pollution. When drying is complete, the hydraulic component is activated. The hydraulic component drives the fixed rod to move from top to bottom, which in turn drives the sealing disc to move from top to bottom. The sealing disc then drives the hammer to move from top to bottom. At this time, the scraper and the second connecting disc inside the heating tank continue to rotate to prevent clumping inside. The sludge will also be exposed from inside the heating tank and will flow out along the discharge pipe. If there is a blockage, the hydraulic component is activated again, which will drive the hammer to move up and down repeatedly to ensure the smooth exposure of the sludge.

[0028] Example

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the technical solution in this application embodiment effectively solves the problem that the device is difficult to adsorb toxic gases. When drying oily sludge, a large amount of toxic gases, such as hydrogen sulfide and ammonia, may be generated. If not handled properly, this may cause environmental pollution. The overall idea is as follows: An oily sludge drying device includes a heating tank 11. The heating tank 11 is equipped with a stirring mechanism, which includes a motor 12, a rotating shaft 13, a first connecting plate 18, a scraper 19, a second connecting plate 21, a stirring rod 22, a synchronous belt drive assembly 23, a first bevel gear shaft 24, and a second bevel gear shaft 25. 5. Connecting rod 26 and fan blade 27, rotating shaft 13 is fixedly installed at the output end of motor 12, first connecting plate 18 is fixedly installed inside rotating shaft 13, second connecting plate 21 is fixedly installed inside rotating shaft 13, scraper 19 is fixedly installed on the side wall of first connecting plate 18, stirring rod 22 is fixedly installed on the side wall of second connecting plate 21, synchronous belt drive assembly 23 is driven and installed on the side wall of rotating shaft 13, first bevel gear shaft 24 is driven and installed inside synchronous belt drive assembly 23, first bevel gear shaft 24 and second bevel gear shaft 25 are meshed and installed, connecting rod 26 is fixedly installed on second bevel gear shaft 25 near first bevel gear shaft 24. At one end, the fan blade 27 is fixedly installed at the end of the second bevel gear shaft 25 away from the connecting rod 26. Sludge is placed inside the heating tank 11. At this time, the heating tank 11 and motor 12 are started. The motor 12 drives the rotating shaft 13 to rotate counterclockwise. The rotating shaft 13 drives the first connecting plate 18 and the second connecting plate 21 to rotate counterclockwise. The first connecting plate 18 and the second connecting plate 21 respectively drive the scraper 19 and the second connecting plate 21 to rotate counterclockwise. The scraper 19 scrapes the inside of the heating tank 11 to prevent excessive sludge accumulation on the inner wall of the heating tank 11. Simultaneously, the scraper 19 and the second connecting plate 21 also clean the sludge inside the heating tank 11. The sludge is stirred to ensure that it is heated evenly. At this time, the rotating shaft 13 drives the synchronous belt drive assembly 23 to rotate counterclockwise. The synchronous belt drive assembly 23 drives the first bevel gear shaft 24 to rotate counterclockwise. The first bevel gear shaft 24 drives the second bevel gear shaft 25 to rotate clockwise. The second bevel gear shaft 25 drives the fan blade 27 to rotate clockwise. The sludge generates steam and toxic gases when heated, which will be sucked into the collection box 28. When the steam and toxic gases pass through the activated carbon plate 33, they will be blocked by the baffle 34 to prevent the activated carbon plate 33 from absorbing too much locally, which would reduce the adsorption capacity. This achieves the function of recovering toxic gases and preventing air pollution.

[0030] A feed pipe is fixedly installed on the side wall of the heating tank 11, and a collection box 28 is rotatably installed on the side wall of the connecting rod 26. The collection box 28 is fixedly installed on the side wall of the heating tank 11. A connecting plate 29 is fixedly installed inside the collection box 28. A protective door 31 is hinged to the side wall of the collection box 28. A slide rail 32 is fixedly installed inside the collection box 28. An activated carbon plate 33 is slidably installed inside the slide rail 32. A baffle 34 is fixedly installed inside the collection box 28 to facilitate quick replacement of the saturated slide rail 32.

[0031] A base 35 is fixedly installed on the side wall of the heating tank 11. A hydraulic component 36 is fixedly installed inside the base 35. A fixing rod 37 is fixedly installed on the top of the hydraulic component 36. A sealing plate 38 is fixedly installed on the top of the fixing rod 37. A hammer 39 is fixedly installed on the top of the sealing plate 38. A discharge pipe 41 is fixedly installed at the bottom of the heating tank 11. The fixing rod 37 is slidably installed inside the discharge pipe 41. When drying is complete, the hydraulic component 36 is activated. The hydraulic component 36 drives the fixing rod 37 to move from top to bottom. The fixing rod 37 drives the sealing plate 38 to move from top to bottom. The sealing plate 38 drives the hammer 39 to move from top to bottom. At this time, the scraper 19 and the second connecting plate 21 inside the heating tank 11 continue to rotate to prevent clumping inside. The sludge will also be exposed from inside the heating tank 11 and will flow out along the discharge pipe 41. When there is a blockage, the hydraulic component 36 is activated again. The hydraulic component 36 will drive the hammer 39 to move up and down reciprocally to ensure the smooth exposure of the sludge.

[0032] To address the problems existing in the prior art, this utility model provides an oily sludge drying device. The sludge is placed inside a heating tank 11. The heating tank 11 and motor 12 are then activated. The motor 12 drives the rotating shaft 13 to rotate counterclockwise, which in turn drives the first connecting plate 18 and the second connecting plate 21 to rotate counterclockwise. The first connecting plate 18 and the second connecting plate 21 respectively drive the scraper 19 and the second connecting plate 21 to rotate counterclockwise. The scraper 19 scrapes away sludge from the inside of the heating tank 11, preventing excessive sludge accumulation on the inner wall. Simultaneously, the scraper 19 and the second connecting plate 21 also stir the sludge inside the heating tank 11, ensuring uniform heating. At this time, the rotating shaft 13 drives the synchronous belt drive assembly 23 to rotate counterclockwise, which in turn drives the first bevel gear shaft 24 to rotate counterclockwise. The first bevel gear shaft 24 then drives the second bevel gear shaft 25 to rotate clockwise. Shaft 25 drives fan blade 27 to rotate clockwise. The sludge is heated and produces steam and toxic gas, which will be sucked into the collection box 28. When the steam and toxic gas pass through the activated carbon plate 33, they will be blocked by the baffle 34 to prevent the activated carbon plate 33 from absorbing too much locally, which would reduce the adsorption capacity. This achieves the function of recovering toxic gas and preventing air pollution. When drying is complete, hydraulic component 36 is activated. Hydraulic component 36 drives fixed rod 37 to move from top to bottom. Fixed rod 37 drives sealing disc 38 to move from top to bottom. Sealing disc 38 drives hammer 39 to move from top to bottom. At this time, scraper 19 and second connecting disc 21 inside heating tank 11 continue to rotate to prevent clumping inside. Sludge will also be exposed from inside heating tank 11 and will flow out along discharge pipe 41. When there is a blockage, hydraulic component 36 is activated again. Hydraulic component 36 will drive hammer 39 to move up and down to ensure the smooth exposure of sludge.

[0033] Working principle:

[0034] The first step involves placing the sludge into the heating tank 11. Then, the heating tank 11 and motor 12 are started. Motor 12 drives the rotating shaft 13 to rotate counter-clockwise, which in turn drives the first connecting plate 18 and the second connecting plate 21 to rotate counter-clockwise. The first connecting plate 18 and the second connecting plate 21, respectively, drive the scraper 19 and the second connecting plate 21 to rotate counter-clockwise. The scraper 19 scrapes the inside of the heating tank 11 to prevent excessive sludge buildup on the inner wall. Simultaneously, the scraper 19 and the second connecting plate 21 also agitate the sludge inside the heating tank 11, ensuring the sludge is evenly heated. When heated, the rotating shaft 13 drives the synchronous belt drive assembly 23 to rotate counterclockwise, which in turn drives the first bevel gear shaft 24 to rotate counterclockwise. The first bevel gear shaft 24 then drives the second bevel gear shaft 25 to rotate clockwise, which in turn drives the fan blades 27 to rotate clockwise. The sludge generates steam and toxic gases when heated, which are then drawn into the collection box 28. When the steam and toxic gases pass through the activated carbon plate 33, they are blocked by the baffle 34 to prevent the activated carbon plate 33 from absorbing too much locally, thus reducing its adsorption capacity and achieving the function of recovering toxic gases and preventing air pollution.

[0035] The second step involves activating the hydraulic assembly 36 when drying is complete. The hydraulic assembly 36 drives the fixed rod 37 to move from top to bottom, which in turn drives the sealing disc 38 to move from top to bottom. The sealing disc 38 then drives the hammer 39 to move from top to bottom. At this time, the scraper 19 and the second connecting disc 21 inside the heating tank 11 continue to rotate to prevent clumping inside. The sludge will also be exposed from inside the heating tank 11 and will flow out along the discharge pipe 41. If there is a blockage, the hydraulic assembly 36 is activated again, which will drive the hammer 39 to move up and down repeatedly to ensure the smooth exposure of the sludge.

Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible.
