Description

Technical Field

[0001] This utility model relates to the field of buffer tank technology, specifically a vertical buffer tank with a cleaning mechanism. Background Technology

[0002] In the lithium battery slurry, coating, food, and cosmetic industries, the production process of slurry often requires storing the mixed slurry or solution in a tank. After use, the inside of the tank inevitably retains a significant amount of slurry, which can solidify and affect reuse. To address this, CN208824311U discloses a wastewater buffer tank, comprising a tank body, a motor protection box, and two stirring shafts. The motor protection box is embedded at the center of the top of the tank body, housing a motor. The motor's output is connected to two stirring shafts, with a fixing plate at the bottom of each shaft. A support bar is fixed to the bottom of the fixing plate via a connecting rod, and the support bar is fixed to the top of a drain ring. The design of the motor and the two stirring shafts effectively stirs the inside of the tank, preventing uneven drainage caused by sediment buildup and improving wastewater flow. The side and oblique scraper designs, driven by the motor, evenly scrape the inner wall of the tank body, preventing sediment from adhering to the inner wall.

[0003] Existing methods of cleaning the interior by rotating side and oblique scrapers driven by a motor, while capable of cleaning after use, have the following shortcomings in actual use: 1. Cleaning by scraping only the inner wall of the buffer tank is ineffective, and a large amount of slurry is easily left on the internal structural components; 2. Slurry adhering to the inner top cannot be cleaned, resulting in poor overall cleaning. In view of this, this application proposes a vertical buffer tank with a cleaning mechanism to solve the above-mentioned problems. Utility Model Content

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1

[0033] like Figures 1 to 3 As shown, the vertical buffer tank with a cleaning mechanism proposed in this embodiment includes:

[0034] The buffer tank body 1 has three L-shaped supports fixedly connected to its bottom in a triangular shape. Its bottom is set with a conical opening structure and connected to a discharge valve 101. Its top is fixedly installed with a cover 102 by four bolts.

[0035] Rotary tube 2 is sealed and rotatably embedded in the bottom of upper cover 102. Its bottom end is set as a sealing structure, and both sides of its bottom are fixedly connected with actuating blades 203. The bottom of upper cover 102 is provided with a circular through hole, and a first sealing bearing is fixedly sleeved in the circular through hole. The inner ring of the first sealing bearing is fixedly sleeved with the outer side of the rotary tube 2, so as to achieve the effect of sealing and rotating the rotary tube 2.

[0036] Protective cover 4 is fixedly connected to the top of the upper cover 102;

[0037] The feed pipe 6 is embedded and fixed on the top right side of the upper cover 102 and is connected to the inside of the buffer tank body 1. The top left side of the feed pipe 6 is connected to the sealing plate 601 by a hinge, and the sealing plate 601 is connected to the feed pipe 6.

[0038] The rotary drive assembly is mounted on the protective cover 4 and fixedly sleeved on the top of the outer side of the rotating tube 2; the rotary drive assembly is used to drive the rotating tube 2 to rotate.

[0039] The water supply assembly is fixedly installed on the top of the protective cover 4 and connected to the top of the rotating pipe 2; the water supply assembly is used to supply water into the rotating pipe 2.

[0040] The rotary scraping cleaning assembly is fixedly connected to the left side of the rotating tube 2 and makes movable contact with the inner wall of the left side and the inner wall of the bottom of the buffer tank body 1; the rotary scraping cleaning assembly is used to scrape and clean the side wall and the inner wall of the bottom of the buffer tank body 1 simultaneously when the rotating tube 2 rotates.

[0041] The rotary jet cleaning and scraping assembly is fixedly connected to the top left side of the rotary pipe 2 and is fixedly connected to the rotary scraping cleaning assembly. The rotary jet cleaning and scraping assembly is used to scrape and clean the bottom of the top cover 102 when the rotary pipe 2 rotates, and is also used to spray and clean the bottom of the top cover 102 and the inside of the buffer tank body 1 when water is supplied into the rotary pipe 2. The agitator 203 is used to rotate and agitate the material in the lower part of the inner side of the buffer tank body 1 when the rotary pipe 2 rotates. When the discharge valve 101 is opened to discharge material, the rotation and agitation form a vortex at the top of the discharge valve 101, which increases the material flow rate and reduces the static jamming phenomenon.

[0042] Furthermore, the sealing plate 601 is threadedly fixed to the feed pipe 6, wherein the feed pipe 6 has a threaded groove on the top right side, and a knob bolt 602 is threadedly screwed into the threaded groove, and the top right side of the sealing plate 601 is threadedly connected to the knob bolt 602.

[0043] The knob-type bolt 602 is designed to engage with the threaded groove to lock the sealing plate 601, preventing water from splashing upwards from the feed pipe 6 during rinsing. By rotating the knob-type bolt 602 in the opposite direction to separate it from the threaded groove, the locking can be released, allowing personnel to rotate the sealing plate 601 upwards to open it, facilitating the unlocking or locking of the sealing plate 601.

[0044] Furthermore, such as Figure 2 and 3 As shown, the rotary drive assembly includes a drive motor 502 fixedly mounted on the top right side of the protective cover 4. The output shaft of the drive motor 502 extends into the protective cover 4 and is fixedly connected to a gear 501. The left side of the gear 501 is engaged with an external gear ring 5 fixedly sleeved on the outside of the rotary tube 2.

[0045] In this embodiment, the drive motor 502, the external gear ring 5, and the gear 501 work together to drive the gear 501 to rotate, and the gear 501 drives the external gear ring 5 that meshes with it to rotate, thereby driving the rotating tube 2 to rotate.

[0046] Furthermore, such as Figure 2 and 3 As shown, the water supply assembly includes a water pump 401 fixedly installed on the top left side of the protective cover 4, a connecting sleeve 402 located inside the protective cover 4 and connected to the top end of the rotating pipe 2, the connecting sleeve 402 is sealed and rotated on the outside of the water outlet of the water pump 401, and a suction hose is connected and fixed to the water inlet of the water pump 401.

[0047] In this embodiment, two second sealing bearings are fixedly fitted inside the connecting sleeve 402. The inner ring of the second sealing bearing is fixedly fitted to the outer side of the outlet of the water pump 401, which achieves the effect of rotating the connecting sleeve 402 from the inside. By using the rotating connection method, when the rotating pipe 2 rotates and drives the connecting sleeve 402 to rotate, the rotational torque can be avoided from being transmitted to the outlet of the water pump 401.

[0048] In this implementation scheme, the water pump 401, the connecting sleeve 402 and the suction hose are used to connect the suction hose to the external water supply pipe. When cleaning after use, the water pump 401 draws water through the suction hose and pumps it into the transfer pipe 2 through the connecting sleeve 402 to achieve the effect of supplying water into the transfer pipe 2.

[0049] Furthermore, such as Figure 2 and 3 As shown, the rotary scraping cleaning assembly includes an inclined support rod 201 fixedly connected to the bottom left side of the rotary tube 2. An L-shaped scraper 202 is fixedly connected to the left end of the inclined support rod 201. The left side and bottom of the L-shaped scraper 202 are in active contact with the inner wall of the left side and the inner wall of the bottom of the buffer tank body 1, respectively.

[0050] In this embodiment, the inclined support rod 201 and the L-shaped scraper 202 work together to drive the L-shaped scraper 202 to rotate when the rotating pipe 2 rotates. The rotation of the L-shaped scraper 202 is used to simultaneously scrape and clean the side wall and bottom inner wall of the buffer tank body 1.

[0051] Furthermore, such as Figure 2 and 3As shown, the rotary spray cleaning and scraping assembly includes a three-way pipe 3 connected to the top left side of the rotary pipe 2. The left side of the three-way pipe 3 is fixedly connected to the top right side of the L-shaped scraper 202. The top of the three-way pipe 3 is fixedly connected to the upper scraper 302. The top of the upper scraper 302 is in contact with the bottom left side of the upper cover 102. The front bottom and front top of the three-way pipe 3 are both connected to and fixed with nozzles 301. There are multiple nozzles 301 located below, which are tilted forward and downward. The tilt angle of the multiple nozzles 301 located below increases from left to right. There are two nozzles 301 located above, which are tilted upward to the left and right respectively. The nozzles 301 located above are also tilted forward.

[0052] In this implementation scheme, the three-way pipe 3, the upper scraper 302, and the nozzles 301 work together. When the rotating pipe 2 rotates, the three-way pipe 3 drives the upper scraper 302 and multiple nozzles 301 to rotate. The rotation of the upper scraper 302 achieves scraping and cleaning of the bottom of the upper cover 102. When water is supplied into the rotating pipe 2, the water enters the three-way pipe 3 and is then sprayed out through the multiple rotating nozzles 301. By using the downward tilting of the lower nozzles 301 and the upward tilting of the upper nozzles, the internal cleaning effect is achieved by simultaneously rotating and spraying the internal parts for comprehensive internal cleaning. The combination of scraping and rinsing effectively ensures the internal cleaning effect.

[0053] It should be noted that both the drive motor 502 and the water pump 401 are fixedly equipped with on / off switches on the front side and are directly electrically connected via flexible wires. Regarding power supply, since the material processing buffer site is a processing and production area, there is no shortage of power supply measures on site. The two electrical components mentioned above are connected to the mains power on site and connected to the power input interfaces of each device through conventional power distribution devices such as circuit breakers, contactors, and power modules (not marked in the figure) to form a complete power supply circuit. This power supply scheme adopts the conventional power distribution and switch operation wiring method of industrial equipment, which is a conventional and mature known technology in this field and will not be described in detail here.

[0054] This embodiment facilitates simultaneous scraping and cleaning of the inner wall of the buffer tank body 1 and the bottom of the top cover 102 after caching, improving the comprehensiveness of internal cleaning. It also facilitates comprehensive internal cleaning by rotating and spraying water during scraping and rinsing after discharge. The water from the rotating spray also rinsing the internal structure by colliding and scattering with the internal structure or solid, reducing the phenomenon of a large amount of slurry residue on the internal structural parts. By combining scraping and rinsing, the comprehensiveness of internal cleaning is effectively guaranteed, and the cleaning effect is improved.

[0055] The usage method of this embodiment is as follows: When using the vertical buffer tank with cleaning mechanism, rotate the knob bolt 602 in the opposite direction to separate it from the threaded groove, which can release the lock so that the personnel can rotate the sealing plate 601 upward to open it. The material is added into the buffer tank body 1 through the feed pipe 6 for buffering. Rotate the sealing plate 601 back to close it, and rotate the knob bolt 602 back to lock the sealing plate 601. When discharging, open the discharge valve 101 and the drive motor 502. The drive motor 502 drives the gear 501 to rotate. The gear 501 drives the rotating tube 2 to rotate through the external gear ring 5 that meshes with it. The rotating tube 2 drives the agitator 203 to rotate, which rotates and agitates the material in the lower part of the inner side of the buffer tank body 1. The rotation and agitation form a vortex at the top of the discharge valve 101, which increases the material flow rate and reduces the phenomenon of the lower part of the material being stuck during discharge.

[0056] When the rotating pipe 2 rotates, the inclined support rod 201 drives the L-shaped scraper 202 to rotate. The rotation of the L-shaped scraper 202 is used to simultaneously scrape and clean the side wall and bottom inner wall of the buffer tank body 1. When the rotating pipe 2 rotates, the three-way pipe 3 also drives the upper scraper 302 and multiple nozzles 301 to rotate. The rotation of the upper scraper 302 is used to scrape and clean the bottom of the upper cover 102. By scraping and cleaning the inner wall of the buffer tank body 1 and the upper cover 102 simultaneously, the effect of comprehensive scraping and cleaning of the inside is achieved, improving the comprehensiveness of the internal cleaning.

[0057] Connect the suction hose to the external water supply pipe. After the material is discharged and transferred, personnel turn on the water pump 401. The water pump 401 draws water from the source through the suction hose and pumps it into the rotary pipe 2 through the connecting sleeve 402. The water enters the three-way pipe 3 and is then sprayed out through multiple rotating nozzles 301. By using the downward tilting of the lower nozzles 301 and the upward tilting of the upper nozzles, the internal scraping and cleaning effect is achieved, which is a comprehensive rotating spray flushing and cleaning effect on the interior after the material is discharged. The water sprayed by the rotation and scattering collides with the internal structure or solid objects, which also has the effect of flushing the internal structure, reducing the phenomenon of a large amount of slurry residue on the internal structural parts. By using scraping and flushing in combination, the internal cleaning is effectively guaranteed to be comprehensive and the cleaning effect is improved.

[0058] Example 2

[0059] like Figures 4 to 5 As shown, this embodiment differs from Embodiment 1 in that: the sealing plate 601 is magnetically fixed to the feed pipe 6, a magnet block 603 is fixedly connected to the top right side of the feed pipe 6, and the sealing plate 601 is made of iron and is attracted to the top of the magnet block 603.

[0060] This embodiment allows personnel to conveniently and directly lock the sealing plate 601 by rotating it upwards to open and downwards to close it by magnetic fixation, further improving the convenience and efficiency of locking and unlocking.

[0061] The method of use in this embodiment is as follows: The difference from the first embodiment is that it also has the following functions: The magnetic block 603 is made of iron in conjunction with the sealing plate 601, so as to facilitate the adsorption and fixation of the sealing plate 601. The magnetic fixation method makes it convenient for personnel to directly apply upward rotation force to open the sealing plate 601. Compared with the threaded locking method, it further improves the convenience and efficiency of locking and unlocking.

[0062] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
