Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the technical field of tar storage tank cleaning, specifically to a tar storage tank cleaning device. Background Technology
[0002] In industrial production such as coking and coal chemical processing, tar storage tanks are key equipment for storing tar. During storage, heavy components and impurities in the tar gradually precipitate and adhere to the inner walls and bottom of the tank, forming a thick layer of waste residue. If this waste residue is not cleaned in time, it will reduce the effective volume of the storage tank, affecting the storage capacity and transportation efficiency of tar, and may even cause production interruptions due to pipeline blockage. Therefore, regular cleaning of tar storage tanks is an important step in ensuring stable production operation.
[0003] Currently, traditional tar storage tank cleaning devices have significant drawbacks in practical applications. On the one hand, the cleaning effect is poor. Due to the high viscosity and strong adhesion of tar waste residue, the scrapers or shovels of existing cleaning devices are mostly fixed structures, making it difficult to fully conform to the curvature or corners of the inner wall and bottom of the storage tank. This results in some areas of waste residue not being completely scraped off, and the residual waste residue continues to accumulate, shortening the cleaning cycle of the storage tank.
[0004] On the other hand, most existing devices lack the function of collecting waste residue and wastewater. During the slag removal process, the scraped-off waste residue mixes with residual tar and water in the storage tank to form a slurry. This mixture flows freely, polluting the surrounding environment, increasing the difficulty of subsequent cleaning, and potentially wasting tar resources. Furthermore, the mixture may seep into the soil, polluting the surrounding ecosystem and failing to meet environmental protection requirements. These drawbacks severely impact the efficiency and environmental friendliness of tar storage tank slag removal. Therefore, it is essential to develop a slag removal device with good scraping effect and the ability to collect waste residue and wastewater. Utility Model Content
[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a tar storage tank cleaning device, which solves the technical problems of poor cleaning effect and inability to collect waste residue and wastewater in the prior art.
[0006] According to one aspect, at least one embodiment of this disclosure provides a tar storage tank cleaning device, comprising:
[0007] A base box and a ring frame, wherein the ring frame is mounted on the base box;
[0008] A support frame and a collection assembly, wherein the support frame is fixed to the base box and the collection assembly is disposed in the base box;
[0009] A slag removal assembly, wherein the slag removal assembly is mounted on the annular frame;
[0010] The slag removal assembly includes an inner frame, which is fixed inside the annular frame. The annular frame is inserted into the bracket through the inner frame. An outer annular frame is slidably connected to the outside of the annular frame. Several fixing seats are fixedly connected to the outer annular frame by bolts, and cleaning scrapers are provided on the fixing seats.
[0011] As a further technical solution, a drive motor is fixedly connected to the surface of the ring frame, a drive wheel is provided at the output end of the drive motor, a protrusion is provided around the inner surface of the outer ring frame, the drive wheel is in contact with the surface of the protrusion, and several outer frames are fixedly connected to the side surface of the ring frame.
[0012] As a further technical solution, a pair of pulleys are rotatably connected to the outer frame, and a movable wheel driven by electricity is installed at the lower end of the side surface of the ring frame. An annular pipe is fixedly connected to the surface of the ring frame.
[0013] As a further technical solution, a connecting pipe is provided on the annular pipe, the connecting pipe passes through the inner frame and the support, and a plurality of flushing nozzles are provided on the surface of the annular pipe, the flushing nozzles being connected at an inclined angle.
[0014] As a further technical solution, the collection component includes a fitting bracket, which is fixed to the side surface of the bottom box and connected to the inside of the bottom box. A discharge pipe is provided on one side of the bottom box.

[0018] The beneficial effects of the embodiments disclosed herein are as follows:
[0019] In this disclosure, the slag removal assembly solves the problem of incomplete cleaning in traditional devices by combining rotary scraping with fluid flushing. The outer ring frame drives the scraper blade to rotate, making it closely adhere to the inner wall of the storage tank, effectively removing slag from corners and curved areas. The moving wheels allow the device to move along the tank, expanding the scraping range. The inclined fluid from the flushing nozzles disperses stubborn slag, preventing secondary adhesion. The double pulleys ensure smooth rotation, and the reliable transmission between the drive wheel and the raised layer allows the scraper blade to operate continuously and efficiently, thoroughly removing high-viscosity tar slag, reducing residue, and extending the storage tank cleaning cycle.

[0031] like Figures 1-3 As shown, it illustrates a tar storage tank cleaning device according to an embodiment of the present disclosure, comprising:
[0032] A base box 1 and a ring frame 2, wherein the ring frame 2 is mounted on the base box 1;
[0033] The bracket 3 and the collection component 5 are provided, wherein the bracket 3 is fixed on the base box 1 and the collection component 5 is disposed in the base box 1;
[0034] Slag removal component 4, which is mounted on the annular frame 2;
[0035] The slag removal assembly 4 includes an inner frame 4-1, which is fixed inside the annular frame 2. The annular frame 2 is inserted into the bracket 3 via the inner frame 4-1. An outer annular frame 4-2 is slidably connected to the outside of the annular frame 2. Several fixing seats 4-3 are fixedly connected to the outer annular frame 4-2 by bolts. A cleaning scraper 4-4 is provided on the fixing seats 4-3. A drive motor 4-5 is fixedly connected to the surface of the annular frame 2. A drive wheel 4-6 is provided at the output end of the drive motor 4-5. A protrusion 4-7 is provided around the inner surface of the outer annular frame 4-2. The drive wheel 4-6 and... The surface of the protruding layer 4-7 is attached. Several outer frames 4-8 are fixedly connected to the side surface of the annular frame 2. A pair of pulleys 4-9 are rotatably connected to the outer frames 4-8. A movable wheel 4-10 driven by electricity is installed at the lower end of the side surface of the annular frame 2. An annular pipe 4-11 is fixedly connected to the surface of the annular frame 2. A connecting pipe 4-12 is provided on the annular pipe 4-11. The connecting pipe 4-12 passes through the inner frame 4-1 and the support 3. Several flushing nozzles 4-13 are provided on the surface of the annular pipe 4-11. The flushing nozzles 4-13 are connected at an inclined angle.
[0036] In some examples, a slag removal assembly 4 is designed to achieve a cleaning effect on the inner wall of the storage tank. This assembly includes an inner frame 4-1 arranged in a straight line inside the annular frame 2. One end of the inner frame 4-1 is fixed to the inner wall of the annular frame 2, and the other end forms an insertion structure that fits into the slot of the bracket 3, allowing the annular frame 2 to be pulled out of the bracket 3 during use. The outer ring frame 4-2 is fitted onto the outside of the annular frame 2 through a sliding structure, and the contact surfaces of the two are lubricated to ensure that the outer ring frame 4-2 can rotate flexibly. The fixing base 4-3 is evenly distributed around the outer ring frame 4-2 and has a cleaning scraper 4-4 fixed inside. The fixing base 4-3 is fixed by bolts, and the blade fits against the inner wall of the storage tank. The bolt connection facilitates the replacement of the scraper according to the wear of the tank wall.
[0037] The drive motor 4-5 is fixed to the surface of the annular frame 2 via the bracket 3. The drive wheel 4-6 at the output end is made of rubber and fits tightly against the raised layer 4-7 on the inner surface of the outer annular frame 4-2. The raised layer 4-7 is continuously distributed around the circumference of the outer annular frame 4-2, forming a transmission track. The outer frame 4-8 on the side surface of the annular frame 2 is symmetrically distributed, and the pulley 4-9 is rotatably connected to the end of the outer frame 4-8, providing movable support for the outer annular frame 4-2, allowing it to move within the storage tank. The moving wheel 4-10 is mounted on the lower end of the side surface of the annular frame 2 via bearings and is driven to rotate by the motor, causing the entire annular frame 2 to move circumferentially along the inner wall of the storage tank to adjust the cleaning position.
[0038] The annular pipe 4-11 is fixed to the surface of the annular frame 2 by a clamp, and is coaxial with the annular frame 2. One end of the connecting pipe 4-12 is connected to the annular pipe 4-11, and the other end extends to the outside through the inner frame 4-1 and the support 3, and is connected to a high-pressure water source or cleaning agent. The flushing nozzles 4-13 are distributed obliquely around the annular pipe 4-11, and the spray direction is directed towards the contact area between the inner wall of the storage tank and the cleaning scraper 4-4. During operation, the drive motor 4-5 drives the drive wheel 4-6 to rotate, which drives the outer ring frame 4-2 to rotate around the annular frame 2 through friction. The cleaning scraper 4-4 rotates with the outer ring frame 4-2 to scrape off the tar residue on the tank wall. The moving wheel 4-10 drives the annular frame 2 to move, expanding the cleaning range. The flushing nozzles 4-13 simultaneously spray high-pressure fluid to flush off the scraped residue and prevent secondary adhesion. The pulley 4-9 ensures the smooth rotation of the outer ring frame 4-2, and the insertion structure of the inner frame 4-1 and the bracket 3 restricts the shaking of the ring frame 2. This component achieves efficient cleaning of the inner wall of the storage tank through the synergy of rotational scraping and directional flushing.
[0039] like Figures 1-3 As shown in the figure, the collection component 5 in this embodiment includes a fitting bracket 5-1, which is fixed to the side surface of the bottom box 1 and is connected to the inside of the bottom box 1. A discharge pipe 5-2 is provided on one side of the bottom box 1.
[0040] In some examples, to achieve centralized collection of cleaning wastewater and slag, a collection component 5 is designed. This component includes a fitting bracket 5-1 on the side surface of the bottom tank 1, made of elastic material (such as wear-resistant rubber), which is fixed by bolts. The edge of the bracket fits tightly against the outer edge of the bottom of the storage tank, forming a sealed structure to prevent wastewater and slag from leaking out during the cleaning process. The fitting bracket 5-1 is hollow inside and communicates with the inside of the bottom tank 1, forming a flow channel so that the scraped slag and flushing wastewater flow into the bottom tank 1 through the bracket.
[0041] The bottom tank 1 has a hollow cavity structure, which can hold a certain amount of wastewater and slag. The discharge pipe 5-2 on the side surface is connected to the bottom of the bottom tank 1. The end of the pipe can be connected to a valve or a transfer pump to control the discharge. The elastic design of the fitting bracket 5-1 allows it to adapt to minor deformations at the bottom of the storage tank, ensuring reliable sealing.
[0042] During slag removal, the mixture of wastewater and slag enters the bottom tank 1 through the bonding bracket 5-1 and is discharged to the treatment equipment through the discharge pipe 5-2. This component, through sealing and guiding, achieves the orderly collection of slag removal waste, prevents pollution to the surrounding environment of the storage tank, and facilitates subsequent waste treatment.
[0043] For example, such as Figure 2 As shown, a rubber strip 6 is provided at the connection point between the fitting bracket 5-1 and the bottom box 1.
[0044] In some examples, the rubber strip 6 at the connection point between the fitting bracket 5-1 and the bottom box 1 is elongated, with its edges tightly fitted to the inner wall of the connection. The rubber strip 6 is elastic, capable of sealing gaps and preventing leakage of slag and wastewater. Simultaneously, it can deform slightly with water flow and slag impact, avoiding wear caused by hard contact, extending the service life of the connection, and ensuring the sealing performance of the collection assembly 5.
[0045] For example, such as Figure 2 As shown, the fitting bracket 5-1 has an overall arc-shaped transition structure, and the arc of the fitting bracket 5-1 matches the arc of the outer wall of the storage tank.
[0046] In some examples, the curved transition structure of the fitting bracket 5-1 matches the curvature of the outer wall of the storage tank, allowing it to fit tightly against the tank. The curved design increases the contact area, improves the sealing effect, and prevents wastewater and slag from leaking out of gaps during slag removal. The curved transition also ensures that the bracket is subjected to uniform stress, avoiding damage from excessive local stress, adapting to the circular structure of the storage tank, and enhancing the applicability of the device.
[0047] For example, such as Figure 1 As shown, pulleys 4-9 are all double-wheel structures.
[0048] In some examples, the double-wheel pulleys 4-9 are symmetrically distributed on both sides of the outer frame 4-8. The double-wheel design restricts the outer ring frame 4-2 from both sides, preventing lateral deviation and ensuring rotational stability. At the same time, the double wheels share the pressure, reducing wear on individual wheels, extending service life, and ensuring that the cleaning scraper 4-4 maintains stable contact with the inner wall of the storage tank, improving the slag removal effect.
[0049] In actual use: Move the device to the side of the tar storage tank, ensuring the fitting bracket 5-1 fits against the outer wall of the tank, with the rubber strip 6 ensuring a seal. Place the bottom box 1 on the outside of the tank bottom. Start the slag removal assembly 4. The drive motor 4-5 drives the drive wheel 4-6 to rotate, which in turn drives the outer ring frame 4-2 to rotate around the ring frame 2 via the protrusion 4-7. The cleaning scraper 4-4 rotates with it, scraping away the waste residue from the inner wall of the tank. The double-wheeled pulley 4-9 assists in the smooth rotation of the outer ring frame 4-2. The moving wheel 4-10 moves the ring frame 2 circumferentially around the tank, expanding the cleaning range. The flushing nozzle 4-13 of the annular pipe 4-11 sprays fluid at an angle to wash away the scraped waste residue. The mixture of waste residue and wastewater flows into the bottom box 1 through the fitting bracket 5-1 and is then discharged through the discharge pipe 5-2 for treatment. After cleaning is complete, shut down the equipment and move the device away from the storage tank.
