Description

Technical Field

[0001] This solution belongs to the field of cleaning equipment technology, specifically involving an automatic cleaning system for textile air conditioning spray rooms. Background Technology

[0002] In textile production, strict requirements are placed on workshop temperature and humidity, and ordinary ventilation equipment cannot accurately control the temperature. Textile air conditioning can stabilize the workshop temperature within the suitable range of 22-28℃, ensuring continuous production. However, textile air conditioning relies on spraying, where atomized water mist comes into contact with the air and cools it rapidly using the latent heat of vaporization. But the spray room requires a water tank for water circulation. After long-term operation, some cotton dust will float on the water surface and some will settle, while salts in the water will precipitate and form scale. If these contaminants are not cleaned, they will clog the pipes and nozzles. Therefore, the spray tank needs to be cleaned regularly.

[0003] A textile factory air conditioning water tank filtration system is disclosed in existing publication (announcement number CN207537252U). The system includes a water tank, an air conditioning return water pipe, a coarse filter, filter screens, a quartz sand layer, an outlet pipe, and an ultrafiltration membrane filter. The air conditioning return water pipe is connected to the upper end of the water tank and is equipped with a coarse filter. Three layers of filter screens are installed in the upper part of the water tank, and three layers of quartz sand are installed in the lower part. The outlet pipe is connected to the lower end of the water tank and is equipped with an ultrafiltration membrane filter. The water is coarsely filtered in the return water pipe, then sequentially filtered through the three layers of filter screens in the upper part of the water tank, with the filter holes decreasing in size to remove impurities sequentially. After further filtration by the three layers of quartz sand in the lower part of the water tank (with holes decreasing in size), the water flows into the outlet pipe. Finally, it is filtered again by the ultrafiltration membrane filter on the outlet pipe to obtain clean water for recycling.

[0004] For example, the air conditioning water tank filtration system mentioned above, although it achieves circulating water purification through multi-stage filtration, the sludge deposited in the tank will first block the connection port between the bottom of the tank and the outlet pipe in the long term, resulting in obstructed circulation of water, which in turn leads to insufficient water supply to the spray room and affects the temperature of the textile workshop. Therefore, it is necessary to clean the sludge regularly to ensure the needs of textile production. Utility Model Content

[0005] The purpose of this solution is to provide an automatic cleaning system for textile air conditioning spray rooms to solve the problem of sludge accumulation in textile air conditioning spray pools.

[0006] To achieve the above objectives, this solution provides an automatic cleaning system for textile air conditioning spray rooms, including a cleaning system installed in a spray pool, the cleaning system comprising: A sewage pump, which is connected to the drain outlet of the spray pool via a sewage pipe; A sludge collection hopper is located at the bottom of the spray pool; A liquid level sensor is installed inside the spray tank and is electrically connected to the sewage pump. It is used to detect the sludge height in the sludge collection hopper and to send a start signal to the sewage pump when the sludge height exceeds a height threshold.

[0007] Furthermore, the top of the sludge collection hopper has a "bowl-shaped" structure.

[0008] Furthermore, the taper of the sludge collection hopper is 60°.

[0009] Furthermore, the cleaning system also includes a mesh screen, which is located inside the spray tank and directly above the sludge collection hopper.

[0010] Furthermore, the mesh is made of stainless steel and has an aperture of 10mm × 10mm.

[0011] Furthermore, the dimensions of the sludge collection hopper and the mesh grid are matched with the inner wall of the spray pool.

[0012] Furthermore, the cleaning system also includes a cleaning scraper, which is disposed in the spray pool, and the rotating shaft of the cleaning scraper is coaxially rotatably connected to the water inlet end of the drain pipe. The cleaning scraper is connected to a drive source for driving its rotation.

[0013] Furthermore, the side of the cleaning scraper closest to the sludge collection hopper is in contact with the sludge collection hopper.

[0014] Furthermore, the sewage pipe is equipped with a pressure sensor for monitoring the pressure inside the sewage pipe.

[0015] Furthermore, it also includes a control cabinet, which contains a controller. The input terminal of the controller is electrically connected to a liquid level sensor and a pressure sensor; the output terminal of the controller is electrically connected to a sewage pump.

[0016] Compared with the prior art, the present invention has the following advantages: 1. Through the structure of mesh grid and bowl-shaped sludge collection hopper, the mesh grid first intercepts large particles of cotton dust and impurities, preventing them from being dispersed and deposited in various parts of the pool; the 60° tapered bowl-shaped sludge collection hopper uses the principle of gravity to quickly collect sludge to the bottom of the hopper, solving the problem of sludge dispersion and deposition and difficulty in centralized cleaning in the existing technology.

[0017] 2. By electrically connecting the liquid level sensor to the sewage pump, the sewage discharge is automatically started when the sludge height exceeds the threshold, without the need for manual intervention or shutdown for sludge removal. This avoids the production interruptions and workshop temperature and humidity fluctuations caused by the need for manual cleaning in existing technologies. Furthermore, it eliminates the need for personnel to enter the humid and harsh water tank environment for manual sludge removal, thus reducing labor costs.

[0018] 3. The cleaning scraper is designed to contact the sludge collection hopper, and its rotating shaft rotates coaxially with the water inlet end of the drain pipe. This design can scrape away the sticky mud and stubborn sludge adhering to the inner wall of the sludge collection hopper, further improving the cleaning effect.

[0019] 4. By monitoring the pressure of the sewage pipe with a pressure sensor and the sludge height with a level sensor, together with the controller in the control cabinet, the system can monitor the operating status in real time and respond promptly in case of equipment failure (such as pipe blockage or sewage pump malfunction).

Detailed Implementation

[0022] The following will describe the concept and technical effects of this utility model clearly and completely with reference to the embodiments, so as to fully understand the purpose, features and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Example 1: Please see Figure 1 This embodiment discloses an automatic cleaning system for a textile air conditioning spray room, including a spray pool 1 and a cleaning system 2 installed within the spray pool 1. The cleaning system 2 includes a sewage pump 21, a sludge collection hopper 22, and a level sensor (not shown). Two sewage pumps 21 are configured, operating in a one-in-one-outstand mode to ensure proper sewage discharge. Each sewage pump 21 has a flow rate of 50 m³ / h and a head of 15 m, capable of extracting concentrated sludge from the sludge collection hopper 22. The sewage pipe 211 is made of corrosion-resistant PVC material, with one end sealed to the inlet of the sewage pump 21 and the other end fixedly connected to the drain outlet 11 at the bottom of the spray pool 1. The diameter of the sewage pipe 211 is DN50. The sludge collection hopper 22 is fixedly installed at the bottom of the spray pool 1, with a bowl-shaped top and a 60° tapered design, allowing sediment to quickly slide to the bottom of the hopper using gravity. The number of sludge collection hoppers 22 is arranged according to the size of the spray pool 1. In this embodiment, one hopper is used. The edge of each sludge collection hopper 22 is tightly fitted to the inner wall of the spray pool 1 to prevent sludge from slipping out through gaps. Each sludge collection hopper 22 has a through hole at the bottom and a corresponding drain outlet 11. The liquid level sensor is a capacitive liquid level sensor, which is vertically installed on the inner side wall of the sludge collection hopper 22. Its detection end is 10cm away from the bottom of the sludge collection hopper 22. It is used to monitor the accumulation height of sludge in the sludge collection hopper 22 in real time. The liquid level sensor is electrically connected to the controller in the control cabinet 25 through a shielded cable. When the sludge height reaches 2 / 3 of the depth of the sludge collection hopper 22 (i.e., the height threshold), the liquid level sensor will send a start signal to the controller.

[0023] Please continue reading. Figure 1It also includes a mesh grille 23 and a cleaning scraper 24. The mesh grille 23 is made of 304 stainless steel with a mesh size of 10mm×10mm. It can block large particles of dust and debris from entering the spray pipe without affecting the normal circulation of the spray water. The mesh grille 23 is laid horizontally above the sludge collection hopper 22, 20cm away from the top of the sludge collection hopper 22. The edge of the mesh grille 23 is fixed to the inner wall of the spray water tank 1 by bolts. Its size fits the inner wall of the spray water tank 1 to prevent debris from leaking from the edge into the outside of the sludge collection hopper 22. The cleaning scraper 24 is made of wear-resistant rubber and its shape is adapted to the bowl-shaped structure of the sludge collection hopper 22. The rotating shaft of the cleaning scraper 24 is coaxially connected to the water inlet end of the sewage pipe 211 through a coupling. The side of the cleaning scraper 24 near the sludge collection hopper 22 is in close contact with the inner wall of the sludge collection hopper 22. The cleaning scraper 24 is connected to a drive source for driving its rotation. In this embodiment, the drive source is a drive motor 241, which is a PID servo motor. The drive motor 241 is located above the spray pool 1 and is fixedly mounted on a bracket (not shown). The output end of the drive motor 241 is connected to a drive shaft 242. The free end of the drive shaft 242 is fixedly connected to the rotation center of the cleaning scraper 24. The drive motor 241 drives the drive shaft 242 to rotate, thereby driving the cleaning scraper 24 to rotate circumferentially along the inner wall of the sludge collection hopper 22, thereby scraping away the sludge accumulated on the top surface of the sludge collection hopper 22 and collecting it at the pipe opening of the sewage pipe 211. It should be noted that, since the drive shaft 242 and the sewage pipe 211 are located on the same central axis, in this embodiment, the connection end between the drive shaft 242 and the cleaning scraper 24 is set to a "cross-shaped" structure, hinged to the cleaning scraper 24 through four symmetrical hinge points. This ensures that there is sufficient gap between this end of the drive shaft 242 and the opening of the sewage pipe 211, allowing sludge to enter the opening of the sewage pipe 211. A pressure sensor (not shown) is installed on the sewage pipe 211 near the sewage pump 21 to monitor the pressure changes in the sewage pipe 211 in real time. The pressure sensor is electrically connected to the controller via a signal cable. When sewage discharge is completed, the pressure in the sewage pipe 211 will drop to a set low-pressure threshold, and the pressure sensor will send a stop signal to the controller. The control cabinet 25 is fixedly installed on the outer wall of the spray pool 1. The control cabinet 25 is equipped with a PLC controller. The input terminal of the controller is electrically connected to the liquid level sensor and the pressure sensor respectively. The output terminal of the controller is electrically connected to two sewage pumps 21. The controller has a pre-stored timed cleaning mode (automatically starts once every 3 days). The operator can set parameters and monitor status through the control panel on the surface of the control cabinet 25.

[0024] In this embodiment, during operation, the circulating water in the spray tank 1, carrying cotton dust and debris, flows through the mesh screen 23. Large particles of impurities are intercepted by the mesh screen 23 and cannot enter the spray pipe; only clean water passes through the mesh screen 23 to participate in the circulation. Under the action of gravity, the intercepted impurities slide down the surface of the mesh screen 23 into the sludge collection hopper 22 below. The 60° tapered sludge collection hopper 22 accelerates the collection of sediment to the bottom of the hopper. The liquid level sensor monitors the sludge height in real time. When the set threshold is reached or a timed cleaning command is triggered, the controller automatically starts. First, the electric valve corresponding to the bottom of the sludge collection hopper 22 is opened, and then the sewage pump 21 is started, prioritizing the main pump. If the main pump fails, the controller will automatically switch to the standby pump and issue an alarm signal. During the sewage discharge process, the pressure sensor monitors the pressure in the sewage discharge pipe 211 in real time. When the pressure drops to the low-pressure threshold, it indicates that the sewage discharge is complete, and the controller automatically closes the electric valve and the sewage pump 21, and the system returns to standby mode. The entire cleaning process does not require stopping the system or draining water, and will not affect the normal operation of the spray system. When the water tank needs to be drained and cleaned, the cleaning scraper 24 is manually rotated to scrape the sludge collected in the sludge collection hopper 22 into the drain outlet 11.

[0025] Example 2: The difference between this embodiment and the previous embodiment is that, since the spray tank 1 mainly stores circulating water, although the circulating water is filtered by a mesh screen to intercept large particles of impurities, it still contains a large number of tiny cotton dust particles, small particles of sludge, etc. These fine pollutants are difficult to settle by gravity and are prone to entering the spray pipe with the circulating water flow if they remain suspended in the water for a long time, leading to nozzle blockage and reduced spraying efficiency. Therefore, this embodiment further improves upon the first embodiment by adding a flocculant to the spray tank 1, causing these tiny pollutants to agglomerate into large flocs, which are easier to monitor by the liquid level sensor and can also accelerate settling into the sludge collection hopper.

[0026] Please see Figure 2 and Figure 3The system also includes a cleaning component 3, which is mounted on a guide rail 4. The guide rail 4 is horizontally positioned in the opposite direction to the length of the spray pool 1. In this embodiment, the guide rail 4 is a linear motor. The cleaning component 4 is driven by a slider on the linear motor to move along the length of the spray pool 1, thereby sequentially stirring the water and adding flocculant. Both the cleaning component 3 and the guide rail 4 are located behind the drive motor 241 and will not affect the operation of the drive motor 241. The cleaning component 3 includes a mixing vessel 31, which comprises a vessel body 311 and a drive rod 312. The drive rod 312 is disposed inside the vessel body 311 and coaxially connected to stirring blades 313 for stirring flocculants. There are two sets of stirring blades 313, spaced apart along the length of the drive rod 312 and located near the bottom of the vessel body 311. One end of the drive rod 312 passes through the bottom of the vessel body 311 and extends into the spray tank 1, where it is connected to a stirring rod 314 for stirring wastewater in the spray tank 1. The number of 14 is in two sets, and they are spaced apart along the length of the drive rod 312. The free end of the drive rod 312 passes through the top of the vessel body 311. The position where the drive rod 312 passes through the vessel body 311 needs to be protected, for example, by using a flange, to prevent liquid leakage from the vessel body 311. The drive rod 312 is connected to a motor 315 for driving the drive rod 312 to rotate. The motor 315 is located on the vessel body 311. The motor 315 is a servo motor with PID servo control, and its speed can be adjusted by PID. The top of the vessel body 311 is connected to a liquid inlet pipe 316, through which the flocculant is added into the stirred vessel 31.

[0027] Please continue reading. Figure 2 and Figure 3In the wastewater treatment process, the flocculant used in this embodiment is cationic polyacrylamide (CPAM), which is particularly suitable for wastewater scenarios containing fine cotton dust and organic sludge, such as textile and air conditioning spray pools. When preparing cationic polyacrylamide, the air inside the stirred tank needs to be replaced with an inert gas (such as nitrogen) to prevent molecular chain oxidation; simultaneously, maintaining a slight positive pressure of 0.02-0.05 MPa further prevents air from re-entering the stirred tank 31. Furthermore, the cleaning component 3 also includes a nitrogen tank 32, which contains a high-pressure nitrogen source. The nitrogen tank 32 is connected to an air pump (not shown) via a pipe. The outlet of the air pump is connected to an inlet pipe 321, and the other end of the inlet pipe 321 passes through the vessel body 311 and communicates with the internal chamber of the vessel body 311. Nitrogen gas from nitrogen tank 32 is introduced into vessel 311 via an air pump to replace the air inside vessel 311. After adding flocculant and various reaction media, nitrogen gas is introduced again via an air pump to maintain a slight positive pressure of 0.02-0.05 MPa inside vessel 311. Then, motor 315 is started to drive drive rod 312 to rotate, which in turn drives stirring blade 313 to rotate, mixing various reaction media and preparing cationic polyacrylamide. After preparation, drain valve at the bottom of stirring vessel 31 is opened to add flocculant into water. During the addition process, motor 315 is controlled to increase speed, driving drive rod 312 and stirring rod 314 to rotate rapidly, thereby rapidly mixing and diffusing flocculant with wastewater.

[0028] Example 3: The difference between this embodiment and Embodiment Two is that, due to the high water level in the spray tank 1, if the stirring rod 314 is only positioned at a fixed liquid level in the spray tank 1, the stirring force and range will be relatively uneven. Furthermore, if the flocculant is added from the liquid surface each time, and only after stirring does it diffuse to the rest of the water, the mixing effect will be relatively poor. Therefore, this embodiment further improves upon Embodiment Two to solve this problem.

[0029] Please see Figure 3 and Figure 4It also includes a telescopic unit 33, which includes a cylinder 331 and a piston 332. The cylinder 331 is located inside the vessel body 311, and its top end is fixedly connected to the output shaft of a motor 315. The motor 315 drives the cylinder 331 to rotate. Air inlets 3311 are provided on both sides of the cylinder 331 and are connected to the vessel body 311. The piston 332 is slidably located inside the cylinder 331 and is interference-fitted with the cylinder 331. A spring 333 is connected to one end of the piston 332, and the free end of the spring 333 is connected to the inner end of the cylinder 331. The piston 332 is fixedly connected to the wall, dividing the cylinder 331 into two chambers: an upper chamber 3312 and a lower chamber 3313. The air inlet 3311 is located in the upper chamber 3312, and the piston 332 is located in the lower chamber 3313. The piston 332 is fixedly connected to one end of the drive rod 312, meaning the drive rod 312 is no longer directly driven by the motor 315. The free end of the drive rod 312 passes through the bottom of the cylinder 331 and is connected in sequence to the stirring blade 313 and the stirring rod 314. The cylinder 331 is driven to rotate by the motor 315, thereby driving the drive rod 312 to rotate. It should be noted that the moving distance of the drive rod 312 is less than the distance between the stirring blade 313 and the vessel body 311, to avoid the stirring blade 313 from colliding with the bottom of the vessel body 311 due to the movement of the drive rod 312.

[0030] Please see Figures 3-5Furthermore, the drive rod 312 is a hollow drive rod 312, and the drive rod 312 has a liquid inlet 3121. The two ends of the air inlet 3121 are respectively connected to the hollow cavity of the drive rod 312 and the vessel body 311. The air inlet 3121 is a flared liquid inlet 3121. A sealing ball 3122 is provided inside the liquid inlet 3121. The sealing ball 3122 is connected to a tension spring 3123. The other end of the tension spring 3123 is fixedly connected to the inner wall of the drive rod 312. In the natural state, the preload of the tension spring 3123 drives the sealing ball 3122 to abut against the liquid inlet 3121, thereby sealing the liquid inlet 3121 and preventing the reaction medium from entering the drive rod 312. When the drive rod 312 rotates at a high speed, the centrifugal force is large. The large centrifugal force causes the tension spring 3123 to drive the sealing ball 3122 away from the liquid inlet 3121. The stirring rod 314 is also a hollow stirring rod 314. The stirring rod 314 is connected to the drive rod 312. The stirring rod 314 has a liquid outlet 3141. There are multiple sets of liquid outlets 3141, which are all spaced apart along the length of the stirring rod 314 and symmetrically arranged in two sets, one above the other, along the central symmetry line of the stirring rod 314. The liquid outlet 3141 is also equipped with a sealing ball 3122 and a tension spring 3123. In normal conditions, the tension spring 3123 drives the sealing ball 3122 to resist the liquid outlet 3141. When the flocculant pressure in the stirring rod 314 exceeds the tension limit of the tension spring 3123, the tension spring 3123 drives the sealing ball 3122 away from the liquid outlet 3141, so that the flocculant enters the drive rod 312 through the liquid inlet 3121, and is sprayed out from the liquid outlet 3141 through the drive rod 312 and the stirring rod 314.

[0031] During operation, after the flocculant is prepared, nitrogen is injected into the vessel 311 through an air pump, which increases the pressure inside the vessel 311. The pressure enters the upper chamber 3312 through the air inlet 3311, which acts on the piston 332 and pushes the piston 332 to move towards the lower chamber 3313. This causes the drive rod 312 to move downward, which in turn causes the stirring rod 314 to move downward in the water body, thereby stirring the sewage in different water layers. Meanwhile, when the drive rod 312 moves the inlet 3121 downwards to contact the liquid surface, the motor 315 drives the cylinder 331 to rotate rapidly, generating a large centrifugal force. This large centrifugal force causes the tension spring 3123 to move the sealing ball 3122 away from the inlet 3121, leaving the inlet 3121 in an open state. As the pressure inside the vessel 311 increases, the pressurized flocculant liquid passes through the inlet 3121, the drive rod 312, and the stirring rod 314, causing the tension spring 3123 in the outlet 3141 to be stretched, which in turn moves the sealing ball 3122 away from the outlet 3141. Finally, the flocculant is sprayed out from the outlet 3141 and follows the stirring rod 314 to deliver flocculant to different water layers.

[0032] Please see Figures 3-5 During the flocculant addition process, the wastewater generally needs to be stirred rapidly to ensure quick mixing of the flocculant and wastewater. Aeration of the wastewater is also typically required to generate numerous bubbles, which, upon bursting, further enhance the mixing effect between the wastewater and flocculant. Furthermore, the air inlet pipe 321 is located below the preset liquid level of the stirred tank 31. With the air inlet pipe 321 positioned below the preset liquid level, after the flocculant is prepared, nitrogen gas is introduced into the tank 311 via an air pump. The stirring blades 313, combined with the nitrogen gas, cause the flocculant to generate a large number of bubbles. These bubbles rise to the liquid surface and are then moved downwards by the drive rod 312, positioning the inlet 3141 above the liquid surface. During operation, the flocculant entering through the inlet 3121 contains a large number of bubbles and is ejected from the outlet 3141. Under the stirring of the stirring rod 314, the flocculant bubbles are mixed into the wastewater and broken by stirring, thus avoiding the need for other aeration equipment to aerate the wastewater while adding flocculant, as required by existing technology.

[0033] Please see Figure 5 and Figure 6 Since the spray tank 1 contains not only sludge particles but also cotton dust floating on the water surface, these cotton dust particles are difficult to flocculate and settle using flocculants. Therefore, a sealing plug 322 is slidably installed inside the nitrogen tank 32. The sealing plug 322 is interference-fitted with the inner wall of the nitrogen tank 32. The sealing plug 322 is connected to a compression spring 323, the free end of which is fixedly connected to the inner wall of the nitrogen tank 32. The sealing plug 322 is used to divide the nitrogen tank 32 into a first chamber 324 and a second chamber 325. The first chamber 324 stores a high-pressure nitrogen source. The second chamber 325 is connected to a slag discharge pipe 326. A float 34 is slidably installed on the drive rod 312. The buoyancy of the float 34 is less than that of the sewage, so that the float 34 can float on the surface of the sewage. A suction nozzle 35 is installed on the float 34, and the suction nozzle 35 is connected to the slag discharge pipe 326 through a flexible hose. During operation, the air pump needs to introduce nitrogen from nitrogen tank 32 into vessel body 311, causing a decrease in pressure in the first chamber 324 of nitrogen tank 32. This causes the sealing plug 322 to move towards the first chamber 324, thereby increasing the space of the second chamber 325 and generating negative pressure. This negative pressure is then applied to the suction nozzle 35 through the slag discharge pipe 326 and flexible hose, with the nozzle 35 floating on the surface of the wastewater. This allows the cotton dust and impurities on the surface of the wastewater to be drawn into the second chamber 325 of nitrogen tank 32 for temporary storage and further processing. Simultaneously, because the surface of the spray pool 1 is relatively wide, the adsorption of cotton dust on the surface during wastewater agitation creates a swirling flow. The cotton dust on the surface rotates to the center of rotation of drive rod 312, facilitating the adsorption of cotton dust and impurities by suction nozzle 35.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
