[0001] This utility model relates to the field of chemical tank cleaning technology, and in particular to a chemical tank bottom cleaning device. Background Technology

[0002] Chemical tanks are a general term for various tank-shaped containers used in chemical industrial production for storing, processing, or transporting raw materials, intermediates, and products. Chemical tanks must be thoroughly cleaned after use to prevent cross-contamination.

[0003] Currently, the main technologies for solving this problem include using fixed spray balls to spray multiple high-pressure water jets to clean the inside of the tank or the cleaning method of "filling the tank with water first and then emptying it (full tank cleaning)". However, these solutions are not only time-consuming, but also require a lot of cleaning media and energy. At the same time, for chemical tanks with conical or spherical bottoms, blind spots are easily created during cleaning, resulting in poor cleaning effect. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, one objective of this utility model is to provide a chemical tank bottom cleaning device that uses an inclined rotating spray method to make the ejected water flow into a turbine shape and impact the tank wall and bottom at a certain angle, thereby enabling comprehensive cleaning of the tank wall and bottom, avoiding blind spots in cleaning, achieving good cleaning effect, saving resources, reducing cleaning time, and improving cleaning efficiency.

[0006] To achieve the above objectives, the first aspect of this utility model provides a chemical tank cleaning device, comprising: a tank body, a cover, a water inlet mechanism, a nozzle mechanism, and a rotating mechanism, wherein the cover is connected to the upper end of the tank body; the water inlet mechanism includes a first water inlet pipe, a second water inlet pipe, and a bend joint, wherein the first water inlet pipe passes through the cover and extends to the middle of the interior of the tank body; one end of the second water inlet pipe is connected to the upper end of the first water inlet pipe; one end of the bend joint is connected to the lower end of the first water inlet pipe, and the other end of the bend joint is inclined downwards; the nozzle mechanism is connected to the bend joint; and the rotating mechanism is disposed between the cover and the first water inlet pipe.

[0007] In addition, the chemical tank cleaning equipment proposed above according to this utility model may also have the following additional technical features: Specifically, the nozzle mechanism includes a housing, a rotating block, a sealing ring, and multiple nozzles. A rotating groove is provided on the inner side of one end of the bent pipe joint. An inlet is provided at one end of the housing. The rotating block is disposed on the inlet of the housing and is adapted to the rotating groove. The sealing ring is sleeved on the outer side of the rotating block. Multiple nozzles are respectively disposed on the outer side of the housing and distributed in a ring array.

[0008] Specifically, the rotating mechanism includes a mounting bracket, a driving component, a first gear, and a second gear. The mounting bracket is disposed on the upper part of the cover. The driving component is mounted on the mounting bracket, and its output end passes through the mounting bracket. The first gear is connected to the output end of the driving component. The second gear is sleeved on the upper part of the first water inlet pipe and meshes with the first gear.

[0009] Specifically, a discharge pipe is provided at the lower part of the tank, and a valve is provided on the discharge pipe.

[0010] Compared with the prior art, the present invention has the following beneficial effects: The chemical tank cleaning equipment of the present invention can spray multiple streams of water through the bent pipe joint and the nozzle mechanism. The reaction force drives the nozzle mechanism to rotate, so that the multiple streams of water generate turbine motion and impact the tank wall and tank bottom at a certain angle. Then, the rotating mechanism drives the nozzle mechanism to revolve around the first water inlet pipe as the center, thereby cleaning the tank wall and tank bottom thoroughly, avoiding cleaning blind spots, ensuring cleaning effect, saving resources, reducing cleaning time, and improving cleaning efficiency.

[0014] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0015] The chemical tank cleaning equipment of this utility model is described below with reference to the accompanying drawings.

[0016] like Figures 1-4 As shown, the chemical tank cleaning device of this utility model embodiment may include: tank body 1, cover 2, water inlet mechanism 3, nozzle mechanism 4 and rotating mechanism 5.

[0017] The cap 2 is connected to the upper end of the tank body 1.

[0018] It should be noted that, in this embodiment, the tank 1 is placed on the ground by means of support legs, and the opening of the tank 1 and the cover 2 are detachably connected by bolts, so that the cover 2 can be removed and reinstalled as the original cover of the tank 1 after cleaning.

[0019] The water inlet mechanism 3 includes a first water inlet pipe 301, a second water inlet pipe 302, and a bend joint 303.

[0020] The first water inlet pipe 301 passes through the cover 2 and extends to the middle of the tank body 1. One end of the second water inlet pipe 302 is connected to the upper end of the first water inlet pipe 301. One end of the bent pipe joint 303 is connected to the lower end of the first water inlet pipe 301, and the other end of the bent pipe joint 303 is inclined downward.

[0021] It should be noted that the first water inlet pipe 301 described in this embodiment is made of stainless steel, which has high strength and good corrosion resistance. At the same time, a sealing bearing is provided between the first water inlet pipe 301 and the cover 2 to ensure sealing while realizing the rotation function of the first water inlet pipe 301.

[0022] Additionally, it should be noted that the second water inlet pipe 302 described in this embodiment is used to connect to an external high-pressure water pump for extracting cleaning agent or clean water. A sealed bearing is also provided between the second water inlet pipe 302 and the first water inlet pipe 301, so that the second water inlet pipe 302 remains stationary when the first water inlet pipe 301 rotates.

[0023] It should be noted that the elbow joint 303 described in this embodiment is made of stainless steel, which has high strength and good corrosion resistance. At the same time, the elbow joint 303 is welded and fixed to the first water inlet pipe 301 to ensure stability and sealing.

[0024] The nozzle mechanism 4 is connected to the elbow joint 303.

[0025] It should be noted that the nozzle mechanism 4 can spray multiple high-pressure water streams and maintain the same tilt angle as the elbow joint 303, so that the sprayed water streams have a certain tilt angle. Among them, the downward sprayed water streams can be aimed at the bottom center of the tank 1.

[0026] The rotating mechanism 5 is located between the cover 2 and the first water inlet pipe 301.

[0027] Specifically, when the chemical raw materials inside the chemical tank are discharged and the inside of the tank 1 needs to be cleaned, the relevant personnel first open the original cover of the chemical tank, and then fix the cover 2 to the upper end of the tank 1, so that the first water inlet pipe 301, the elbow joint 303 and the nozzle mechanism 4 extend into the inside of the tank 1.

[0028] Next, the second water inlet pipe 302 is connected to an external high-pressure water pump, which is connected to the cleaning agent or water source. Then, the high-pressure water pump is started, and the cleaning agent or clean water enters the nozzle mechanism 4 through the second water inlet pipe 302, the first water inlet pipe 301 and the elbow joint 303. The nozzle mechanism 4 sprays out a turbine-shaped water flow that impacts the side wall and bottom of the tank 1. At the same time, the reaction force drives the nozzle mechanism 4 to rotate at high speed, so that multiple water flows form a circular water surface with a certain tilt angle. The water surface can cover the tank wall and the bottom of the tank.

[0029] Finally, the rotating mechanism 5 is activated, which drives the first water inlet pipe 301 to rotate. The first water inlet pipe 301 drives the elbow joint 303 and the nozzle mechanism 4 to rotate, thereby controlling the vortex water surface to rotate around the center of the bottom of the tank 1, so as to thoroughly clean the tank wall and bottom, avoid cleaning blind spots, and improve cleaning efficiency and effect.

[0030] After cleaning, the relevant personnel will remove the cover 2 and take the equipment out of the tank 1, and then install the original cover back onto the tank 1.

[0031] In one embodiment of this utility model, such as Figure 3As shown, the nozzle mechanism 4 includes a housing 401, a rotating block 402, a sealing ring 403, and multiple nozzles 404.

[0032] The elbow joint 303 has a rotating groove 405 on the inner side of one end, the housing 401 has an inlet at one end, the rotating block 402 is set on the inlet of the housing 401 and is adapted to the rotating groove 405, the sealing ring 403 is sleeved on the outside of the rotating block 402, and multiple nozzles 404 are respectively set on the outside of the housing 401 and distributed in a ring array.

[0033] It should be noted that the nozzle 404 described in this embodiment has a fan-shaped cross-section, so that multiple nozzles 404 can spray water along the tangential direction of the housing 401. The multiple water streams generate turbine motion, and the reaction force drives the housing 401 to rotate at high speed in conjunction with the rotating block 402 and the rotating groove 405, so that the water stream continuously moves and sweeps across the tank wall and tank bottom to clean the residual chemical products.

[0034] Understandably, the sealing ring 403 plays a sealing role during the rotation of the housing 401 to prevent water leakage.

[0035] In one embodiment of this utility model, such as Figure 4 As shown, the rotating mechanism 5 includes a mounting bracket 501, a driving component 502, a first gear 503, and a second gear 504.

[0036] The mounting bracket 501 is located on the upper part of the cover 2. The drive component 502 is mounted on the mounting bracket 501 and its output end passes through the mounting bracket 501. The first gear 503 is connected to the output end of the drive component 502. The second gear 504 is sleeved on the upper part of the first water inlet pipe 301 and meshes with the first gear 503.

[0037] It should be noted that the driving component 502 described in this embodiment can be a motor.

[0038] Specifically, when the drive unit 502 is started by the external control device, the drive unit 502 will drive the first gear 503 to rotate, the first gear 503 will drive the second gear 504 to rotate, the second gear 504 will drive the first water inlet pipe 301 to rotate, thereby the first water inlet pipe 301 will drive the elbow joint 303 and the nozzle mechanism 4 to rotate, so that the water flow fully covers the tank wall and the bottom of the tank, avoiding the occurrence of cleaning blind spots.

[0039] Additionally, it should be noted that the second gear 504 described in this embodiment is welded and fixed to the first water inlet pipe 301 to ensure connection strength and stability.

[0040] In one embodiment of this utility model, such as Figure 2 As shown, a discharge pipe 6 is provided at the lower part of the tank body 1, and a valve 7 is provided on the discharge pipe 6.

[0041] Understandably, after cleaning the inner wall and bottom of tank 1, valve 7 can be opened to allow the wastewater generated during the cleaning process to be continuously discharged through discharge pipe 6, thus preventing wastewater from accumulating inside tank 1.

[0042] In summary, the chemical tank cleaning equipment of this utility model can spray multiple water streams through the combination of the bent pipe joint and the nozzle mechanism. The reaction force drives the nozzle mechanism to rotate, causing the multiple water streams to generate turbine motion and impact the tank wall and bottom at a certain angle. Then, the rotating mechanism drives the nozzle mechanism to revolve around the first water inlet pipe as the center, thereby enabling comprehensive cleaning of the tank wall and bottom, avoiding cleaning blind spots, ensuring cleaning effect, saving resources, reducing cleaning time, and improving cleaning efficiency.
