Description

Technical Field

[0001] This utility model relates to the field of reaction tank operation and maintenance, specifically a bottom cleaning device for reaction tanks. Background Technology

[0002] In the structural design of many chemical reaction tanks, the central bottom position is reserved for outlets for material discharge, drainage, and oil discharge, and the bottom often has a narrowing funnel-shaped structure. After a period of use, these reaction tanks often experience material accumulation and adhesion to the walls at the bottom, requiring regular cleaning. Existing methods often involve adding a spray system inside the tank or using external spray facilities connected through inspection ports or manholes for flushing. However, because the spray facilities are mostly located at the top of the tank, combined with the funnel-shaped bottom, this area is difficult to clean thoroughly by flushing alone, especially when encountering sticky materials or materials adhering to the walls, making cleaning even more difficult. Currently, manual scrubbing of the bottom or direct entry into the manhole is often used, which is not only labor-intensive but also creates a harsh working environment and increases the risk of inhaling harmful gases. Utility Model Content

[0003] The purpose of this invention is to provide a bottom cleaning device for reaction tanks, which can scrub the inclined surface at the bottom of the tank, achieving efficient and thorough cleaning and effectively solving the problem of material sticking to the bottom.

[0021] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0022] Example 1:

[0023] Based on the premise of focusing on cleaning the bottom, this example is a standalone external cleaning device. Its main structure includes a movable base 1. The base 1 can be equipped with corner wheels or other structures to facilitate movement. A motor and a rotating seat are mounted on the top surface of the base 1. A vertical shaft 2 is rotatably mounted on the rotating seat. The vertical shaft 2 is driven by the output shaft of the motor through a common transmission structure. For example, the vertical shaft 2 is provided with a driven pulley, and the output shaft of the motor is provided with a driving pulley. A transmission belt is wound between the driving pulley and the driven pulley. Another example is that a speed-changing gearbox is mounted on the output shaft of the motor, and the output shaft of the speed-changing gearbox is geared to the vertical shaft 2. It is not limited to the examples in this example. Other common transmission structures can be used to drive the vertical shaft 2 to rotate.

[0024] The top of the vertical shaft 2 is fixed with a coaxial vertical tube 3. The vertical tube 3 is a rectangular tube and can be obtained by cutting and processing square steel tubes, not limited to this example. It can also be processed by processing round steel tubes. Square tubes are easy to cut and position, so it is simpler for our workshop to process. The vertical tube 3 has a hollow cavity inside. The top of the vertical tube 3 is hinged to a swing cylinder 4 located in the cavity. The bottom of the swing cylinder 4 is provided with a swing cylinder 4 rod that is telescopically coordinated with it. The top of the vertical tube 3 is provided with a clearance opening 5 corresponding to the telescopic and swing stroke range of the swing cylinder 4 and the swing cylinder 4 rod. The clearance opening 5 is used to provide space for the swing and telescopic movement of the swing cylinder 4. Below the clearance opening 5 is a fixed hinge seat 6 welded to the side wall of the vertical tube 3. A swing connecting rod 15 is hinged to the fixed hinge seat 6. The swing connecting rod 15 is provided with an eccentric mounting seat 7 near the fixed hinge seat 6. The bottom of the swing cylinder 4 rod is hinged to the mounting seat 7 to realize the driving and control of the angle of the swing connecting rod 15. Based on the above structure, the swing link 15 has a swing stroke relative to the vertical tube 3.

[0025] The riser 3 has a horizontal through-hole 8 in its middle section, which is located below the fixed hinge seat 6. The riser 3 has a slider 9 with a cross-section adapted to its cavity, which slides up and down relative to the riser 3. A lifting hinge seat 10 is fixed to one side of the slider 9, and a lower connecting rod 16 is hinged to the lifting hinge seat 10. In this example, the lower connecting rod 16 and the swing connecting rod 15 are of the same length. A side connecting rod 11 is provided between the lower connecting rod 16 and the swing connecting rod 15 and is hinged to the first and last ends of both. The top end of the side connecting rod 11 is hinged to the end of the swing connecting rod 15 away from the fixed hinge seat 6, and the bottom end of the side connecting rod 11 is hinged to the end of the lower connecting rod 16 away from the lifting hinge seat 10. Based on the swing of the swing hinge seat and the lifting of the lifting hinge seat 10, the angle of the side connecting rod 11 and its distance relative to the riser 3 can be changed and controlled.

[0026] A lifting cylinder 12 is fixedly installed at the bottom of the cavity. The top of the lifting cylinder 12 is provided with a lifting cylinder 12 rod that is telescopically coordinated with it. The top of the lifting cylinder 12 rod is fixed to the bottom of the slider 9 and is used to control and drive the slider 9 to lift and lower, thereby indirectly controlling the angle of the lower connecting rod 16, as well as the angle and position of the side connecting rod 11.

[0027] Cleaning components are fixed to the side connecting rod 11 and the lower connecting rod 16 respectively. The cleaning component is a brush plate 13. The outer side of the brush plate 13 is provided with bristles. The side of the brush plate 13 away from the bristles is provided with a mounting groove plate 14. The groove of the mounting groove plate 14 corresponds to the width of the side connecting rod 11 and the lower connecting rod 16. The mounting groove plate 14 is inserted into the outer side of the side connecting rod 11 / lower connecting rod 16. The cleaning component can be quickly fixed by screws passing through the mounting groove plate 14 and the side connecting rod 11 / lower connecting rod 16, and it is convenient to replace the worn cleaning component.

[0028] Based on the above structure, this device can have the following morphological variations (not exhaustive; specific settings can be made according to needs in specific applications):

[0029] State 1: such as Figure 5 As shown, the swing cylinder 4 retracts into the swing cylinder 4, the swing rod moves upward toward the riser 3, the angle between the swing rod and the riser 3 is no greater than 105 degrees, the slider 9 is located in the middle of its lifting and sliding stroke, so that the lower connecting rod 16 moves upward toward the riser 3, the side connecting rod 11 moves toward the riser 3, the swing connecting rod 15, the side connecting rod 11, and the lower connecting rod 16 are gathered together near the riser 3 to form a bundle, which facilitates entry or exit from the tank opening at the bottom of the reaction tank;

[0030] State 2: such as Figure 1 , 2As shown, the swing cylinder 4 retracts into the swing cylinder 4, the swing rod moves upward towards the vertical pipe 3, the angle between the swing rod and the vertical pipe 3 is no greater than 105 degrees, the slider 9 slides upward in the state 1 position until the tilt angle of the lower connecting rod 16 corresponds to the slope of the tank bottom, and the tank bottom can be brushed by rotating the vertical shaft 2.

[0031] State 3: such as Figure 2 , 3 As shown, the swing cylinder 4 extends to swing the swing rod outward, and the angle between the swing rod and the vertical pipe 3 gradually increases. Simultaneously, the slider 9 slides downward, making the lower connecting rod 16 parallel to the swing rod and the side connecting rod 11 vertical. Combined with the rotation of the vertical shaft 2, the side wall can be scrubbed. By adjusting the swing angle of the swing connecting rod 15 and the height of the slider 9, the distance between the side connecting rod 11 and the vertical pipe 3 can be adjusted, allowing the side connecting rod 11 to be used to scrub the side walls of tanks of different sizes.

[0032] Based on the above, the components can be used to achieve the effect of entering and exiting the bottom of the tank and cleaning the bottom and the side walls of the tank. Combined with the internal spraying, the bottom of the reaction tank can be thoroughly cleaned, solving the problem of wall adhesion. Moreover, no personnel need to enter or scrub, reducing the labor intensity and difficulty of the operation.

[0033] Example 2:

[0034] Based on Embodiment 1, a mobile trolley is provided below the base 1, and a lifting mechanism is provided between the mobile trolley and the base 1. The lifting mechanism can be a scissor lift or a screw jack. This allows it to automatically rise and insert into the bottom of the tank without relying on an external ladder structure. This facilitates easy adjustment of the relative position and height to the tank, further increasing operational convenience.
