For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0036] A large amount of oil sludge is produced in the process of oil exploitation, transportation, smelting, storage and refining. The basic composition of oil sludge includes various petroleum hydrocarbon composition complex emulsifiers, water, heavy metals, silt and various chemical agent residues. The harmful components in the oil sludge can cause serious harm to the surrounding environment and human health during long-term stacking. The sulfide, benzene series, phenolic, anthracene and other harmful substances contained in the oil sludge have carcinogenic, teratogenic and mutagenic effects on some hydrocarbon substances. At the same time, the soil is polluted in the process of producing oil sludge, and the organic matter content in the oil sludge is high, which not only pollutes the soil. At present, the oil pollution and the contaminated soil are treated by ex situ thermal desorption process, and the contaminated soil or oil sludge is indirectly or directly heated by ex situ thermal desorption equipment. After discharging, cooling and heat exchange treatment is needed. In the cooling and heat exchange treatment process of the existing slag cooler, the material (contaminated soil, oil sludge) is easy to adhere to the equipment.

[0037] In view of the above problems, in order to avoid the problem of material adhering to the equipment as much as possible, the present application provides a drum type slag cooler. Referring to Figure 1 The drum type slag cooler can include a cylinder 100 and a rapping mechanism 200. The cylinder 100 has a material heat exchange cavity 110 inside. The rapping mechanism 200 is connected with the cylinder 100, and the rapping mechanism 200 is used to knock the cylinder 100 under the action of the rotation of the cylinder 100, so that the material adhering to the cylinder 100 is vibrated, and the material falls off from the cylinder 100.

[0038] The drum type slag cooler provided by the embodiments of the present application. The material exchanges heat in the material heat exchange cavity 110 inside the cylinder 100. When the material adheres to the cylinder 100, the cylinder 100 rotates. In this way, the knocking mechanism 200 knocks the cylinder 100, so that the material vibrates and falls off from the cylinder 100. In this way, the material adhering to the cylinder 100 is avoided.

[0039] In some embodiments of the present application, in order to realize the knocking of the knocking mechanism 200 to the cylinder 100. Referring to Figure 2 The knocking mechanism 200 can include a knocking base 210 and a knocking connecting rod 220. The knocking base 210 is installed on the cylinder 100. For example, the knocking base 210 is welded, screwed or integrally formed with the cylinder 100, which is not limited in the present application. The first end of the knocking connecting rod 220 is rotatably installed on the knocking base 210, and the second end of the knocking connecting rod 220 is used to knock the cylinder 100. Specifically, the first end of the knocking connecting rod 220 is rotatably installed on the knocking base 210 through a pin shaft, which is simple in structure and convenient to install.

[0040] Based on the above, the knocking connecting rod 220 can include a connecting rod body 230 and a knocking wheel 240. The first end of the connecting rod body 230 is rotatably installed on the knocking base 210. The knocking wheel 240 is rotatably installed on the second end of the connecting rod body 230. Specifically, the first end of the connecting rod body 230 is rotatably installed on the knocking base 210 through a pin shaft. The knocking wheel 240 is rotatably installed on the second end of the connecting rod body 230 through a pin shaft, which facilitates the disassembly and assembly of the knocking wheel 240. In addition, the knocking wheel 240 can be fixed on the second end of the connecting rod body 230 by welding or screwing.

[0041] In some embodiments of the present application, in order to realize the cooling and temperature reduction treatment of the material, referring to Figure 3The shown cylinder body 100 can include an inner cylinder body 120, an outer cylinder body 130 and a beating block assembly 140. The inner cylinder body 120 forms a material heat exchange cavity 110 inside. The outer cylinder body 130 is sleeved on the outer cylinder body 120, and a cold source cavity 150 is formed between the outer cylinder body 130 and the inner cylinder body 120, which is used to accommodate cooling liquid. The cooling liquid can be cooling water. The cooling water in the cold source cavity 150 cools the material in the material heat exchange cavity 110 through heat conduction. The outer cylinder body 130 is provided with a plurality of mounting holes in communication with the cold source cavity 150. The mounting holes are not shown in the figure, and the beating base 210 is mounted on the outer cylinder body 130. The beating block assembly 140 is arranged at the mounting hole and connected to the outer wall of the inner cylinder body 120 close to the outer cylinder body 130. Part of the beating block assembly 140 penetrates through the mounting hole and is exposed outside the mounting hole, which is used to contact the beating mechanism 200 when the beating mechanism 200 knocks the cylinder body 100. Specifically, the beating block assembly 140 mounted at the mounting hole can prevent the cooling water in the cooling cavity 150 from flowing out through the mounting hole.

[0042] Based on the above, in order to realize how the beating block assembly 140 cooperates with the beating mechanism 200 to knock the cylinder body 100. Referring to Figure 4 The shown beating block assembly 140 can include a first guard plate 141, a first sleeve 142 and a beating block 143. The first guard plate 141 is mounted on the outer wall of the inner cylinder body 120 close to the outer cylinder body 130. For example, the first guard plate 141 can be connected to the outer wall of the inner cylinder body 120 by welding or screws, which is not limited in the present application. One end of the first sleeve 142 is mounted on the first guard plate 141, and the other end of the first sleeve 142 extends outside the outer cylinder body 130 through the mounting hole. The first sleeve 142 is welded together with the first guard plate 141 at one end, which makes the installation more stable. The first sleeve 142 is welded to the inner wall of the mounting hole, so that the mounting hole is isolated from the cold source cavity 150, avoiding the cooling water in the cold source cavity 150 flowing out through the mounting hole. The beating block 143 is located in the first sleeve 142, one end of the beating block 143 is mounted on the first guard plate 141, and the other end extends outside the first sleeve 142. The beating block 143 is used to contact the beating wheel 240 when the beating wheel 240 knocks the cylinder body 100.

[0043] Referring to Figure 5 The shown cylinder body 100 rotates in the direction indicated by the arrow, and the connecting rod body 230 rotates around the connecting point of the connecting rod body 230 and the beating base 210. In this case, the beating wheel 240 also rotates, and when it rotates to the beating block 143, the beating wheel 240 knocks the beating block 143, so that the cylinder body 100 vibrates and the material adhering to the inner cylinder body 120 falls off.

[0044] Based on the above. In some embodiments of the present application, in order to improve the heat exchange efficiency of the roller type slag cooler. Referring toFigure 6 The shown drum-type slag cooler also comprises a plurality of cooling pipe rows 300 installed in the material heat exchange cavity 110. For example, there can be six cooling pipe rows 300, less than six cooling pipe rows 300 resulting in poor heat exchange effect, and more than six cooling pipe rows 300 occupying a large installation space. In addition, the cooling pipe rows 300 can be in communication with the cold source cavity 150 to realize the circulating flow of cooling water in the cooling pipe rows 300 and the cold source cavity 150, thereby increasing the heat exchange efficiency. The inner wall of the inner cylinder 120 is sprayed with an anti-sticking coating, so that dust is not easy to adhere to the inner wall of the inner cylinder 120, thereby improving the heat exchange coefficient.

[0045] Based on the above, the present application is exemplified by six cooling pipe rows 300. One side of the plurality of cooling pipe rows 300 is connected, and the other side is connected with the inner wall of the inner cylinder 120 respectively. The plurality of cooling pipe rows 300 divide the material heat exchange cavity 110 into a plurality of sub-cavities 111, and the cooling pipe rows 300 are provided with through holes 310, and the plurality of sub-cavities 111 are in communication through the through holes 310. The beating block 143 is located in the first extension direction (D direction) of the cooling pipe rows 300; the first extension direction is the same as the radial direction of the cylinder 100, so that the vibration generated by the beating wheel 240 knocking the beating block 143 directly acts on the cooling pipe rows 300, so that the cooling pipe rows 300 generate greater vibration. Six cooling pipe rows 300 divide the material heat exchange cavity 110 into six sub-cavities 111. During the rotation of the cylinder 100, the material will leak from one sub-cavity 111 to the adjacent other sub-cavities 111 through the through holes 310 of the cooling pipe rows 300, thereby realizing the scattering of the material and increasing the radiation heat transfer. At the same time, the material will also impact the material in other sub-cavities 111 during the scattering process under the action of its own gravity, thereby destroying the surface tension of the adsorbed material, so that the material is not easy to adhere to the inner wall of the cooling pipe rows 300 and the inner cylinder 120, thereby improving the heat exchange efficiency.

[0046] Based on the above, with reference to Figure 7 The shown drum-type slag cooler can also comprise a central pipe 320. The central pipe 320 has a hollow structure. The central pipe 320 is located in the material heat exchange cavity 110 and is coaxially arranged with the inner cylinder 120. One side of the plurality of cooling pipe rows 300 is connected with the outer wall of the central pipe 320, and the other side is connected with the inner wall of the inner cylinder 120 respectively, thereby improving the installation stability of the cooling pipe rows 300. In this case, one end of the central pipe 320 is in communication with the cooling pipe rows 300, thereby facilitating the rapid distribution of cooling water in each cooling pipe row 300 through the central pipe 320, thereby improving the cooling and heat exchange efficiency of the cooling water on the material.

[0047] In addition, in some embodiments of the present application, with reference to Figure 8The cooling pipe row 300 shown can include two support plates 330, a plurality of heat exchange pipes 340, a connecting plate 350 and a guide plate 360. The heat exchange pipes 340 are in communication with the central pipe 320. The two support plates 330 are respectively located at two ends of the central pipe 320, one end of the two support plates 330 is welded or bolted on the central pipe 320, and the other end of the two support plates 330 is welded or bolted on the inner wall of the inner cylinder 120. The two support plates 330 are arranged in parallel. The plurality of heat exchange pipes 340 are uniformly and spacedly arranged between the two support plates 330 and connected with the two support plates 330. The connecting plate 350 is arranged between adjacent two heat exchange pipes 340 to further fix the heat exchange pipes 340. The through hole 310 is arranged on the connecting plate 350. The guide plate 360 is welded on the heat exchange pipe 340 and the connecting plate 350 to realize the conveying of the material.

[0048] As can be seen from the above, with reference to Figure 9 The cylinder 100 shown can include an inner cylinder 120 and an outer cylinder 130. The inner cylinder 120 forms a material heat exchange cavity 110 inside. The outer cylinder 130 is sleeved outside the inner cylinder 120, and a cold source cavity 150 is formed between the outer cylinder 130 and the inner cylinder 120, which is used to accommodate cooling liquid. A plurality of mounting holes are formed in the outer cylinder 130 and are in communication with the cold source cavity 150. The knocking mechanism 200 can include a second sleeve pipe 410 and a first knocking ball 420. The second sleeve pipe 410 is L-shaped, which can also be arc-shaped structure. The first end of the second sleeve pipe 410 is mounted on the outer wall of the inner cylinder 120 close to the outer cylinder 130, the bent part of the second sleeve pipe 410 passes through the mounting hole and is located outside the outer cylinder 130; the second end of the second sleeve pipe 410 is closed. The first knocking ball 420 is located in the second sleeve pipe 410 and freely moves in the second sleeve pipe 410. Specifically, during the rotation of the cylinder 100, the first knocking ball 420 will be brought to the tail end of the second sleeve pipe 410, and after the cylinder 100 rotates by a certain angle, the first knocking ball 420 will slide to the outer wall of the inner cylinder 120 under the rotation force of the cylinder 100 and its own gravity, thereby knocking the inner wall of the inner cylinder 120, so that the material adhering to the inner wall of the inner cylinder 120 falls off under the vibration force, thereby achieving the purpose of preventing adhesion. The first end of the second sleeve pipe 410 is located in the first extension direction (E direction) of the cooling pipe row 300. The first extension direction is the same as the radial direction of the cylinder 100, so that the first knocking ball 420 preferentially vibrates the cooling pipe row 300, so that the material on the cooling pipe row 300 is vibrated and falls off.

[0049] Based on the above, with reference to Figure 10 The knocking mechanism 200 shown can further include a second guard plate 430. The second guard plate 430 is mounted on the outer wall of the inner cylinder 120 close to the outer cylinder 130 and connected with the outer wall of the outer cylinder 130 and the second sleeve pipe 140, so as to avoid damage to the cylinder 100 caused by the excessive impact force of the first knocking ball 420.

[0050] In some embodiments of the present application, referring to Figure 11 The drum-type slag cooler shown in the figure can further include a connecting pipe 440 and a second beating ball. The second beating ball is not shown in the figure, the connecting pipe 440 has a circular arc structure, and the connecting pipe 440 is located between and connected with adjacent cooling pipe rows 300. The second beating ball is located in the connecting pipe 440 and freely moves in the connecting pipe 440. The second beating ball 450 directly strikes the cooling pipe row 300 to make the material on the cooling pipe row 300 vibrate and fall off in the case of rotation of the cylinder body 100.

[0051] Based on the above, in some embodiments of the present application, referring to Figure 12 The drum-type slag cooler shown in the figure can further include two groups of supporting wheels 500, a chassis 600, and a driving motor 700. The two groups of supporting wheels 500 are respectively rotatably connected to the two sides of the chassis 600. The outer cylinder body 130 is provided with a support ring 510 corresponding to the supporting wheels 500, and the support ring 510 is in sliding abutment with the supporting wheels 500. Thus, the rotation of the cylinder body 100 relative to the chassis 600 is realized. As known from the above, the cylinder body 100 is provided with the beating mechanism 200. Therefore, the distance between the outer cylinder body 130 and the chassis 600 is greater than the length of the beating mechanism 200, so as to avoid the beating mechanism 200 from contacting the chassis 600.

[0052] In order to avoid the outer cylinder body 100 from moving along the axial direction on the chassis 600, the support ring 510 is provided with a stop roller 520 on both sides, the stop roller 520 is in sliding abutment with the support ring 510, and the stop roller 520 is rotatably connected with the chassis 600. In this way, the support ring 510 is limited between the stop rollers 520. The driving motor 700 is installed on the chassis 600, and the driving motor 700 is in transmission connection with the outer cylinder body 130 through a chain or a gear transmission, so as to drive the rotation of the cylinder body 100. In order to facilitate the conveying, feeding, and discharging of the material, the inner wall of the inner cylinder body 120 is provided with a spiral guide piece 710, one end of the inner cylinder body 120 is a feeding port, and the other end of the inner cylinder body 120 is a discharging port. The material added from the feeding port is conveyed to the discharging port through the spiral guide piece 710 and the flow guide plate 360, so as to continuously cool and exchange heat with the material. The outer cylinder body 130 is provided with a safety valve 720 in communication with the cold source cavity 150. The safety valve 720 is mainly used for pressure relief when the cooling water in the cold source cavity 150 is heated and expanded due to too high temperature of the material caused by shutdown, so as to prevent explosion.

[0053] Based on the above, referring to Figure 13 The drum-type slag cooler shown in the figure can further include a feeding chute 730, a discharging cover 740, and a rotary joint 750. A sealing door is provided at the feeding port to seal the feeding port and avoid material spilling. Referring to Figure 14One end of the shown feed chute 730 extends into the inner cylinder 120 through the sealing door, and the other end of the feed chute 730 is connected with the chassis 600 through a support shaft 760, thereby supporting and fixing the feed chute 730. The feed chute 730 is connected with the sealing door through a dynamic and static sealing ring, so that the cylinder 100 rotates, the feed chute 730 does not rotate, and the connection is sealed. The material is added into the inner cylinder 120 through the feed chute 730. A bidirectional poking hole 770 is arranged on the feed chute 730 along the material feeding direction, and a cleaning rod is arranged in the bidirectional poking hole 770, which is not shown in the figure. When blockage occurs, the cleaning rod can be pulled out to achieve smooth flow of the blocked material. There is no need to stop and clean the material. In addition, in order to avoid splashing of the material during discharging, the discharge cover 740 is installed at the discharge port through a dynamic and static sealing ring, so that the cylinder 100 rotates and the discharge cover 740 does not rotate. The lower end of the discharge cover 740 is fixed on the chassis 600. After cooling, the material is discharged through the slag outlet 780 at the lower end of the discharge cover 740.

[0054] Referring to Figure 15 In order to facilitate observation of the situation in the material heat exchange cavity 110 and maintenance thereof, the discharge cover 740 is provided with a manhole 790 and an observation hole 800. A safety door is hingedly installed at the manhole 790, and the observation hole 800 is a transparent observation window. Figure 14 The rotary joint 750 is installed on the discharge cover 740. The inner pipe of the rotary joint 750 is connected with the central pipe 320, and the outer pipe of the rotary joint 750 is connected with the cooling source cavity 150. The inner pipe of the rotary joint 750 is used for discharging cooling liquid, and the outer pipe of the rotary joint 750 is used for discharging cooling liquid, so that the cooling liquid is circulated and cooled to cool the material.
