Description

Technical Field

[0001] The utility model relates to the technical field of water seal tank cleaning, in particular to a device for cleaning mud residue at the bottom of a water seal tank. Background Art

[0002] A large number of coking furnaces are used in the industrial production process, and each coking furnace has a matching carbonization chamber. A riser is set on the top of the carbonization chamber. The coking furnace needs to be aired before use, and the smoke in the carbonization chamber will be discharged through the riser during the airing. For a large number of risers, a movable gas collection hood is provided to collect the smoke in the risers one by one. The collected smoke will be discharged to the smoke collection pipe through the smoke pipe. The smoke pipe will pass through the water seal tank to perform preliminary treatment on the smoke during the smoke guiding process. At the same time, it can prevent the leakage of harmful substances. When the smoke and dust pass through the water seal tank, the smoke and dust will fall into the bottom of the water seal tank to form mud. Most of the existing methods are to move the smoke pipe in the water seal tank, and drive the mud at the bottom of the water to move to the slag discharge tanks at both ends of the water seal tank for cleaning. The effect is poor. When a large amount of mud accumulates at the bottom of the water seal tank, it is necessary to have cleaning personnel enter the water seal tank to clean the mud at the bottom when stopping work, which increases the labor intensity of the cleaning personnel, and the harmful substances in the mud will cause the risk of injury to the cleaning personnel. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a mud residue cleaning device at the bottom of a water seal tank. By setting the horizontal height of the bottom of the water seal tank to a structure that gradually decreases from the middle to both ends, since the first sleeve and the second sleeve can be relatively telescopic under the action of the elastic member, it is convenient for the cleaning component to cooperate with the bottom of the water seal tank, and it is convenient to ensure that the scraper is always in contact with the bottom of the tank body, further ensuring the cleaning effect, eliminating the need for cleaning personnel to enter the bottom of the tank body for cleaning, and reducing the labor intensity of cleaning personnel.

[0004] To achieve the above purpose, the present invention provides the following technical solutions:

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1

[0027] A device for cleaning mud residue at the bottom of a water seal tank, the structure of which is as follows Figures 1-6 As shown, a tank body 1 including a water seal tank is provided on the side of the tank body 1. A flue 2 is provided on the top of the tank body 1 and the top of the flue 2. The side of the flue 2 away from the tank body 1 is higher than the height of the side of the tank body 1. An L-shaped partition 3 is installed on the side of the flue 2 away from the tank body 1. The end of the partition 3 away from the flue 2 extends into the opening of the tank body 1. Rails 18 are provided on the opposite sides of the tank body 1 and the flue 2. A movable frame is installed on the rail 18. A smoke guide device is provided at the bottom of the movable frame. The smoke guide device includes A U-shaped smoke guide tube 4 is located inside the trough body 1 and connects both sides of the partition 3. A cleaning assembly is provided at the bottom of the U-shaped smoke guide tube 4, and the cleaning assembly includes a first sleeve 13 whose length is adapted to the width of the trough body 1. A telescopic second sleeve 15 is sleeved in the first sleeve 13. An elastic member 14 is provided through the second sleeve 15 and the first sleeve 13. The bottom end of the elastic member 14 is connected to the top of the second sleeve 15. The bottom end of the second sleeve 15 is provided with a scraper 16 that can abut against the bottom of the trough body 1.

[0028] Since the trough body 1 and the flue 2 are arranged side by side and abutting each other, rails 18 are provided on the sides of the trough body 1 and the flue 2 that are away from each other, so that the movable frame can move on the rails 18 and drive the smoke guide device to move to the top of each riser.

[0029] Since the horizontal height of the side of the flue 2 away from the trough body 1 is higher than the horizontal height of the top of the trough body 1, an L-shaped partition 3 is provided on the side of the flue 2 with a higher horizontal height and extends into the trough body 1. Water is poured into the trough body 1, and the height of the horizontal plane is higher than the height of the end of the partition 3 extending into the inner end of the trough body 1, which can isolate the flue 2 from the outside. The outside and the flue 2 can be connected through the U-shaped smoke guide pipe 4, which facilitates the collection of smoke and dust in the riser into the flue 2 through the U-shaped smoke guide pipe 4. When the smoke and dust enter the side where the flue 2 and the trough body 1 are connected, the smoke and dust can be preliminarily treated with water;

[0030] When the furnaces are dried one by one, the mobile frame drives the smoke guide device to move to the top of each riser one by one. When the furnaces are dried, the smoke generated by each riser can pass through the smoke guide device on the mobile frame one by one into the flue 2. Since the smoke guide device includes a U-shaped smoke guide pipe 4, and the U-shaped smoke guide pipe 4 is arranged inside the trough body 1, connecting the flue 2 and the external riser, when the smoke passes through the U-shaped smoke guide pipe 4 and enters the connection between the trough body 1 and the flue 2 separated by the partition 3, the smoke can come into contact with the water in the trough body 1 and can be preliminarily treated by the water, and the impurities in the smoke will fall into the water and sink to the bottom of the water to form mud residue. Since the bottom of the U-shaped smoke guide pipe 4 is provided with a first sleeve 13 and a second sleeve 15 sleeved in the first sleeve 13, the first sleeve 13 and the second An elastic member 14 is provided between the sleeves 15, and a scraper 16 abutting against the bottom of the trough body 1 is provided at the bottom end of the second sleeve 15. When the movable frame moves, it can drive the scraper 16 at the bottom of the U-shaped smoke guide pipe 4 to clean the bottom of the trough body 1. Since slag discharge grooves 17 are provided at both ends of the bottom of the trough body 1, and the horizontal height of the bottom of the trough body 1 gradually decreases from the middle toward the slag discharge grooves 17 at both ends, it is convenient for the mud residue at the bottom of the trough body 1 to be effectively cleaned, and the first sleeve 13 and the second sleeve 15 can be relatively extended and retracted under the action of the elastic member 14, so as to ensure that the scraper 16 is always abutted against the bottom of the trough body 1, further ensuring the cleaning effect, and there is no need for cleaning personnel to enter the bottom of the trough body 1 for cleaning, thereby reducing the labor intensity of cleaning personnel.

[0031] A water inlet and an overflow port are provided on the side of the tank body 1 , and slag discharge troughs 17 are provided at both ends of the bottom of the tank body 1 . The level of the bottom of the tank body 1 gradually decreases from the middle to the two ends.

[0032] The water inlet and overflow port are set to ensure that the water level in the tank body 1 is always at the moving height, avoiding smoke leakage due to the lowering of the water level, and ensuring the sealing of the water seal tank. The slag discharge troughs 17 set at both ends of the bottom of the tank body 1 can clean the mud residue at the bottom of the water seal tank into the slag discharge trough 17 when the mobile frame moves. A drainage pipe is set inside the slag discharge trough 17. After the production work is completed, the mud residue in the slag discharge trough 17 is cleaned through the drainage pipe under the action of water flow.

[0033] The scraper 16 is detachably arranged at the bottom end of the second sleeve 15. The cleaning component is made of stainless steel metal, and the scraper 16 is made of polyurethane material.

[0034] The first sleeve 13, the second sleeve 15 and the elastic member 14 are all made of stainless steel metal, which can improve their corrosion resistance and ensure service life. By setting the scraper 16 to polyurethane material, the scraper 16 can be prevented from scratching the bottom of the water seal groove, and at the same time, the mud residue at the bottom of the water seal groove can be effectively cleaned. The detachable scraper 16 can be replaced in time when the scraper 16 is damaged.

[0035] The cleaning components are arranged on both sides of the bottom end of the U-shaped smoke guide pipe 4 , and the size of the slag discharge groove 17 is larger than the width of the U-shaped smoke guide pipe 4 .

[0036] Cleaning components are respectively provided on both sides of the bottom of the U-shaped smoke guide tube 4. By cleaning with two scrapers 16 at the same time, the cleaning effect of the bottom of the trough body 1 can be increased. Since the size of the slag discharge trough 17 is larger than the width of the U-shaped smoke guide tube 4, it is convenient for the two scrapers 16 to clean the mud residue between the two scrapers 16 into the slag discharge trough 17, avoiding mud residue residue and improving the cleaning effect.

[0037] One end of the U-shaped smoke guide pipe 4 extends out of the trough body 1 through the L-shaped second smoke guide pipe 9, and the end of the second smoke guide pipe 9 away from the U-shaped smoke guide pipe 4 is connected to the L-shaped first smoke guide pipe 7 through the first adapter 6. The end of the first smoke guide pipe 7 away from the first adapter 6 is installed with a gas collecting hood 5, and the other end of the U-shaped smoke guide pipe 4 is connected to the flue 2 through the third smoke guide pipe 10.

[0038] Since the partition 3 divides the water seal groove into two parts, and the part where the partition 3 is connected to the flue 2 is in the sealed part, the U-shaped tube can bypass the partition 3 to connect the two parts. One end of the U-shaped smoke guide pipe 4 can be connected to the flue 2 through the third smoke guide pipe 10. The other end of the U-shaped smoke guide pipe 4 is installed with an L-shaped second smoke guide pipe 9, and then the second smoke guide pipe 9 and the L-shaped first smoke guide pipe 7 are connected through the first adapter 6. The bottom end of the first smoke guide pipe 7 is installed with a gas collecting hood 5 on the top of the riser, which is convenient for guiding the smoke and dust in the riser into the flue 2.

[0039] The mobile frame includes a frame body 19, and support legs 20 are respectively provided at the four corners of the bottom of the frame body 19. The bottom ends of the support legs 20 are provided with rollers 22 adapted to the rails 18. A connecting rod 21 is provided between the support legs 20 on the same side. A clamping device is provided between the bottom of the frame body 19 and the connecting rod 21. The clamping device includes a first clamping plate 23 and a second clamping plate 24. The first clamping plate 23 is provided at the bottom of the frame body 19, and the second clamping plate 24 is provided at the top of the connecting rod 21. The second smoke guide pipe 9 is clamped between the first clamping plate 23 and the second clamping plate 24.

[0040] The rollers 22 on the support legs 20 of the mobile frame can cooperate with the rails 18 to move the mobile frame. The first clamping plate 23 and the second clamping plate 24 at the bottom of the frame body 19 can clamp the second smoke guide pipe 9, so that the smoke guide device can be moved when the mobile frame moves.

[0041] Water splitters 8 are respectively provided on both sides of the outside of the U-shaped smoke guide pipe 4 , and one end of the flue 2 is connected to the smoke collecting pipe 12 through a second adapter 11 .

[0042] When the U-shaped smoke guide tube 4 moves in the water seal groove following the movable frame, there is water in the water seal groove, and the U-shaped smoke guide tube 4 will have a large resistance when moving. The water splitter 8 provided can further reduce the resistance of the water to the U-shaped smoke guide tube 4, ensuring that the U-shaped smoke guide tube 4 can move quickly. At the same time, it can avoid damage to the connection between the smoke guide device and the movable frame due to water resistance, thereby improving the service life of the device.

[0043] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes, additions, subtractions, or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
