Description

Technical Field

[0001] The invention relates to the technical field of pollutant treatment and regeneration, and in particular to a reaction pool sediment collection and centralized treatment system. Background Art

[0002] In the field of metal parts processing and manufacturing, industrial reaction tanks are the core equipment for completing key processes such as pickling, electroplating, anodizing, and chemical dyeing. During the production process, the workpieces are orderly transferred and immersed in multiple reaction tanks through the overhead crane system. With continuous operation, composite sediments composed of metal salt crystals, suspended particles, and reaction by-products will gradually accumulate at the bottom of the reaction tank. These sediments form a dense hardened layer after long-term standing, which will not only change the effective concentration and physical and chemical parameters of the chemical solution, but also directly affect the surface treatment quality of the workpiece.

[0003] Currently, mainstream sediment cleaning processes can be divided into two categories:

[0004] (1) Chemical solution emptying and cleaning method

[0005] The advantages of manual desilting by completely emptying the reaction tank of chemical solution are high thoroughness of cleaning (removal rate > 95%) and low technical requirements for operation. However, there are significant limitations: first, it involves the scrapping of chemical solution (single tank processing capacity reaches 3-5 tons), which directly leads to material loss of tens of thousands of yuan; second, the operation cycle is as long as 8-12 hours (including drainage, cleaning, injection, parameter debugging, etc.), causing partial shutdown of the production line; third, the newly injected chemical solution needs to re-establish a stable chemical reaction balance, which affects the stability of the initial processing quality.

[0006] (2) In-situ cleaning method

[0007] Mechanical equipment is used to clean sediments while retaining chemical solutions. The main equipment types and their characteristics are as follows:

[0008]

[0009]

[0010] Although other new equipment such as high-pressure jet devices and underwater robots perform well in clean water environments, they face serious constraints in industrial chemical solution environments: the former will produce drug atomization pollution, and the latter is limited by the cost of corrosion-resistant materials and navigation obstacles of complex pool structures, as well as the corrosive effect of the drug solution itself on the underwater robot.

[0011] Therefore, there are still significant technical challenges in developing efficient dredging equipment that can adapt to industrial chemical solution environments, and breakthroughs are needed in dimensions such as material compatibility, dredging efficiency, and process interference. Summary of the invention

[0012] In view of the above-mentioned deficiencies or defects in the prior art, the present invention provides a reaction pool sediment collection and centralized treatment system, which can clean the sediment in the reaction pool without sucking away the liquid in the reaction pool.

[0013] In order to achieve the above-mentioned object, the present invention provides a reaction tank sediment collection and centralized treatment system, comprising a track, a carrier vehicle traveling along the track, and a centralized treatment system located at one end of the track.

[0019] In some embodiments, the centralized processing system includes a collection box, a dehydrator, a filter, a liquid storage tank, and a solid storage tank. After the carrier runs to the location of the centralized processing system, the temporary storage box can be connected to the collection box to transfer the materials in the temporary storage box to the collection box.

[0020] The outlet of the collecting box is connected to the inlet of the dehydrator, the liquid outlet of the dehydrator is connected to the filter, the outlet of the filter is connected to the liquid storage tank, and the solid outlet of the dehydrator is connected to the solid storage tank.

[0021] In some embodiments, the same chemical solution is contained in the multiple reaction pools that the track passes through. A regeneration reactor is arranged between the filter and the liquid storage tank of the centralized treatment system, the inlet of the regeneration reactor is connected to the outlet of the filter, and the outlet of the regeneration reactor is connected to the inlet of the liquid storage tank. A stirrer is arranged in the regeneration reactor.

[0022] In some embodiments, the end of the mechanical arm is connected to one end of an extension arm, and an adsorption head is installed at the end of the extension arm away from the mechanical arm. When working, the extension arm extends into the reaction pool, the adsorption head connected to the bottom of the extension arm contacts the bottom of the pool, and the top of the extension arm is above the liquid surface.

[0023] In some embodiments, the extension arm is hollow and tubular, and the mud suction airflow channel is formed in the hollow cavity of the extension arm; a spiral conveying rod is arranged inside the extension arm, and a driving motor is fixed on the top of the extension arm, and the driving motor drives the spiral conveying rod to rotate. An air outlet is provided on the side of the top of the extension arm, and the air outlet is connected to the negative pressure air source through a pipeline, and the bottom opening of the extension arm is connected to the mud suction pipe of the adsorption head.

[0024] In some embodiments, the mud suction system further includes a controller, an air intake flow sensor, an air outlet flow sensor, an air intake flow control valve, and an air outlet flow control valve.

[0025] The intake flow sensor and the outlet flow sensor are electrically connected to the controller and send the collected signals to the controller. The controller is electrically connected to the intake flow control valve and the outlet flow control valve respectively, and the controller controls the opening and closing of the intake flow control valve and the outlet flow control valve.

[0026] The air intake flow sensor is arranged on the pipeline between the positive pressure air source and the adsorption head, and the air intake flow control valve is arranged on the pipeline between the air intake flow sensor and the adsorption head.

[0027] The outlet air flow sensor is arranged on the pipeline between the separator and the adsorption head, and the outlet air flow control valve is arranged on the pipeline between the negative pressure gas source and the separator.

[0031] In some embodiments, a conveyor is disposed at the bottom of the temporary storage box, and a terminal end of the conveyor is aligned with an outlet of the temporary storage box.

[0032] In the traditional underwater dirt cleaning process, dirt is transported using liquid as the transport medium. During the cleaning process, a large amount of liquid will be sucked away at the same time as the dirt is sucked away. Dirt that has been deposited for a long time and has a harder texture requires a scraper or other tools to loosen the dirt, and then the loosened dirt is sucked away. Because during the dirt loosening process, scrapers and other tools will disturb the water body, accelerating the dirt to drift around. In order to prevent the dirt from drifting, it is necessary to increase the flow rate of the sucked liquid and suck away more liquid. Otherwise, the dirt is carried to a position far away from the adsorption head by the disturbed liquid during the loosening process, and reattaches to the bottom of the pool after standing, affecting the dirt cleaning effect.

[0033] Therefore, the most common practice in the prior art is to empty the reaction tank, centrally clean it, and finally refill it with the reaction chemical solution.

[0034] The above technical solution of the present invention is used to collect and centrally treat sediment in a reaction pool, which has the following effects:

[0035] The present invention sets the suction system and suction head for adsorbing the sediment at the bottom of the pool on a carrier, and the carrier runs on a track, which passes through the reaction pools to be cleaned in sequence. When the carrier runs to the location of the reaction pool to be cleaned, the suction head is inserted into the reaction pool by the mechanical arm on the carrier and moves along the bottom of the pool to complete the adsorption and cleaning of the sediment at the bottom of the pool.

[0036] The suction head of the present application is provided with a water-proof cover, and the positive pressure air source of the mud suction system blows air into the water-proof cover to empty the liquid in the water-proof cover to form a positive pressure chamber. The suction port of the mud suction pipe is arranged in the positive pressure chamber, and the negative pressure source of the mud suction system is connected to the mud suction pipe, and the sediment at the bottom of the pool is sucked away with air as the medium, instead of sucking away a large amount of chemical solution with liquid as the medium like the traditional mud suction machine.

[0037] After the temporary storage box in the carrier is full, the carrier can run along the track to the centralized processing system to transfer the sediment in the temporary storage box to the centralized processing system. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] The specific embodiments of the present invention are described in detail below. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0052] The present invention provides a reaction tank sediment collection and centralized treatment system 6, comprising a track 2, a carrier vehicle 1 traveling along the track 2, and a centralized treatment system 6 located at one end of the track 2.

[0053] Track 2, see Appendix Figure 1 , the track 2 passes through a plurality of reaction pools 7 in sequence. The track 2 here can be either an actual steel rail or guide rail for carrying the carrier 1, or a virtual running line. When the track 2 is a physical steel rail, the carrier 1 can be an EMS trolley that cooperates with the steel rail. When the track 2 is an aerial track, the carrier 1 can be an overhead crane that can run along the aerial track 2. When the track 2 is a virtual line, the carrier 1 can be a tracking trolley or an AGV trolley.

[0054] Carrier 1, see attached Figure 3 and Figure 4 The carrier 1 is provided with a sludge suction system 3. The carrier 1 is also provided with a mechanical arm 4. An adsorption head 5 is installed at the end of the mechanical arm 4. The mechanical arm 4 can be inserted into the reaction tank 7 so that the adsorption head 5 fits the bottom of the reaction tank 7. The carrier 1 can run along the route specified by the track 2. The carrier 1 is provided with an operation control system for controlling the carrier 1 to run to a specific location of the reaction tank 7.

[0055] Adsorption head 5, see attached Figure 5 The adsorption head 5 is used to adsorb the sediment at the bottom of the reaction tank 7 below the liquid surface. The adsorption head 5 includes a mud suction tube 5a. A suction port is provided at the bottom of the mud suction tube 5a. A water-proof cover 5b is arranged at the bottom of the mud suction tube 5a. The water-proof cover 5b is sleeved on the mud suction tube 5a. The bottom opening of the water-proof cover 5b is a bowl-shaped structure inverted on the bottom of the tank, and a positive pressure chamber is formed in the water-proof cover 5b. A positive pressure chamber is formed by blowing air into the water-proof cover 5b inverted on the bottom of the tank. The positive pressure chamber is an air environment. The adsorption port of the mud suction tube 5a adsorbs sediments from the air environment, and the sucked air is replenished into the water-proof cover 5b by the positive pressure air source 3a, and it is only necessary to keep the amount of blown air ≥ the amount of air extracted.

[0056] Suction system 3, see attached Figure 3 The mud suction system 3 includes a positive pressure air source 3a, a negative pressure air source 3b, a separator 3c and a temporary storage box 3d, wherein the negative pressure air source 3b is connected to the separator 3c. The feed port of the separator 3c is connected to the mud suction pipe 5a of the adsorption head 5 through a pipeline. A discharge port is arranged at the bottom of the separator 3c, and the temporary storage box 3d is arranged below the separator, and the discharge port of the separator 3c is connected to the temporary storage box 3d.

[0057] The negative pressure gas source is used to generate suction to suck away the sediment. A separator 3c is arranged between the negative pressure gas source 3b and the adsorption head 5. The separator 3c separates the gas and the sediment, and the sediment moves downward into the temporary storage box 3d. The positive pressure gas source 3a is responsible for blowing air into the water-proof cover 5b of the adsorption head 5 to maintain the air environment in the water-proof cover 5b.

[0058] Centralized processing system6, see Appendix Figure 2 The centralized processing system 6 is used to collect and process the sediment in the temporary storage box 3d.

[0059] Centralized processing system 6:

[0060] See attached Figure 2 The centralized treatment system 6 includes a collection box 6a, a dehydrator 6b, a filter 6c, a liquid storage tank 6e and a solid storage tank 6f. The centralized treatment system 6 is arranged at one end of the track 2. When the temporary storage box 3d of the carrier 1 is full, the carrier 1 moves to the location of the centralized treatment system 6 and transfers the mixture of sediment and chemical solution stored in the temporary storage box 3d to the collection box 6a. The carrier 1 can then leave the centralized treatment system 6 and continue the sediment adsorption work.

[0061] The following methods can be used to transfer the sediment from the temporary storage tank 3d to the collection tank 6a:

[0062] (1) The collecting box 6a is open, and the top of the collecting box 6a is open without a box cover. After the transport vehicle 1 runs above the collecting box 6a, the temporary storage box 3d discharges the sediment into the collecting box 6a below.

[0063] (2) The inlet of the collection box 6a and the outlet of the temporary storage box 3d are configured as flanges that can be docked and matched with each other. During operation, the outlet of the temporary storage box 3d is connected with the inlet of the collection box 6a, and then the sediment stored in the temporary storage box 3d is transferred.

[0064] The outlet of the collecting box 6a is connected to the inlet of the dehydrator 6b. The liquid outlet of the dehydrator 6b is connected to the filter 6c. The outlet of the filter 6c is connected to the liquid storage tank 6e. The solid outlet of the dehydrator 6b is connected to the solid storage tank 6f.

[0065] Among them, the collecting box 6a is not limited to the form of a box body. When the factory is large in scale and there are more sediments to be processed, it can also be set in the form of a collecting pool. A scraper is installed at the bottom of the collecting box 6a, and the scraper guides the sediment to the outlet of the collecting box 6a. The function of the dehydrator 6b is to separate solids and liquids. As a system for processing sediments in the factory reaction tank 7, its processing capacity is usually not large, and the processing operation is intermittent. Therefore, it is more appropriate to use a centrifugal separator 3c as the separator 3c. The separated chemical solution flows into the filter 6c from the liquid outlet and is filtered and then enters the liquid storage tank 6e. Solid waste enters the solid storage tank 6f.

[0066] Under the condition that the same chemical solution is contained in the multiple reaction pools 7 that the track 2 passes through, the entire centralized treatment system 6 processes the same type of chemical solution. At this time, the following settings can be used to achieve the recycling of chemical solutions. Specifically, a regeneration reactor 6d is set between the filter 6c and the liquid storage tank 6e of the centralized treatment system 6. The inlet of the regeneration reactor 6d is connected to the outlet of the filter 6c. The outlet of the regeneration reactor 6d is connected to the inlet of the liquid storage tank 6e. At the same time, a dosing device is also required to be set up, and the dosing device injects the regeneration agent into the regeneration reactor 6d. Figure 2 In the figure, the icon on the upper left corner of the regeneration reactor 6d is a dosing device. A bypass pipeline is provided between the filter 6c and the liquid storage tank 6e. When necessary, the liquid can bypass the regeneration reactor 6d via the bypass pipeline. A stirrer is provided in the regeneration reactor 6d.

[0067] Robotic Arm 4:

[0068] See attached Figure 1 , Figure 3 , Figure 4 A mechanical arm 4 is provided on the carrier 1. The mechanical arm 4 is a servo system for operating the adsorption head 5, and the adsorption head 5 is moved and operated by the mechanical arm 4. The bottom of the adsorption head 5 is in contact with the bottom of the pool, and the adsorption head 5 can move along the bottom of the pool.

[0069] The chemical solution contained in the reaction tank 7 of the factory, whether it is acid, alkali or electrolyte, is often highly corrosive. If the robot arm 4 is directly extended into the reaction tank 7, its servo motor, reducer and rotating shaft are easily corroded and fail by the chemical solution. Therefore, the present invention is provided with an extension arm 4a, the extension arm 4a is inserted into the reaction tank 7, and the main body of the robot arm 4 is maintained outside the reaction tank 7. The end of the robot arm 4 is connected to one end of the extension arm 4a. An adsorption head 5 is installed at one end of the extension arm 4a away from the robot arm 4. During operation, the extension arm 4a is extended into the reaction tank 7, the adsorption head 5 connected to the bottom of the extension arm 4a contacts the bottom of the tank, and the top of the extension arm 4a is located above the liquid level.

[0070] The extension arm 4a is in the shape of a hollow tube. The mud suction airflow channel is formed in the hollow cavity of the extension arm 4a. A spiral conveying rod 4b is arranged inside the extension arm 4a. A driving motor is fixed on the top of the extension arm 4a. The driving motor drives the spiral conveying rod to rotate. An air outlet is provided on the top side of the extension arm 4a, and the air outlet is connected to the negative pressure air source 3b through a pipeline. The bottom opening of the extension arm 4a is connected to the mud suction pipe 5a of the adsorption head 5.

[0071] Suction system 3

[0072] The mud suction system 3 includes a positive pressure air source 3a, a negative pressure air source 3b, a separator 3c and a temporary storage box 3d. The negative pressure air source 3b is connected to the separator 3c. The feed port of the separator 3c is connected to the mud suction pipe 5a of the adsorption head 5 through a pipeline. The bottom of the separator 3c is connected to the temporary storage box 3d below the separator 3c. The positive pressure air source 3a is connected to the positive pressure chamber through an air blowing pipe. The negative pressure air source is used to generate suction to suck away the sediment. A separator 3c is arranged between the negative pressure air source 3b and the adsorption head 5. The separator 3c separates the gas and the sediment. The sediment moves downward into the temporary storage box 3d. The positive pressure air source 3a is responsible for blowing air into the water-proof cover 5b of the adsorption head 5 to maintain the air environment inside the water-proof cover 5b.

[0073] In order to control the balance of air intake and air extraction in the water-blocking cover 5b. The mud suction system 3 also includes a controller, an air intake flow sensor, an air outlet flow sensor, an air intake flow control valve, and an air outlet flow control valve. The air intake flow sensor and the air outlet flow sensor are electrically connected to the controller and send the collected signal to the controller. The controller is electrically connected to the air intake flow control valve and the air outlet flow control valve respectively. The controller controls the opening and closing of the air intake flow control valve and the air outlet flow control valve.

[0074] The inlet air flow sensor is arranged on the pipeline between the positive pressure air source 3a and the adsorption head 5. The inlet air flow control valve is arranged on the pipeline between the inlet air flow sensor and the adsorption head 5. The outlet air flow sensor is arranged on the pipeline between the separator 3c and the adsorption head 5. The outlet air flow control valve is arranged on the pipeline between the negative pressure air source 3b and the separator 3c.

[0075] Adsorption head 5:

[0076] Reference Figure 5 The suction head 5 includes a mud suction pipe 5a, an air inlet pipe, a water-proof cover 5b, a cleaning brush and a baffle 5c.

[0077] The mud suction pipe 5a is used to suck away dirt. The bottom of the mud suction pipe 5a is provided with a suction port, and the mud suction pipe 5a is connected to the inlet of the separator 3c through a pipeline.

[0078] The water-blocking cover 5b is installed at the bottom of the mud suction pipe 5a. The top of the water-blocking cover 5b is sleeved on the mud suction pipe 5a and sealed, and the bottom is open. The water-blocking cover 5b is in a bowl-shaped structure and is inverted on the bottom of the pool. The water-blocking cover 5b and the bottom of the pool enclose a positive pressure chamber, and the suction port is opened downward and placed in the positive pressure chamber. The water-blocking cover 5b is in the shape of an inverted bowl, and a suction port and a cleaning brush are arranged in the water-blocking cover 5b. The water-blocking cover 5b is usually made of stainless steel or hard plastic. The top opening of the water-blocking cover 5b is provided for the mud suction pipe 5a to pass through, and the mud suction pipe 5a extends from the top of the waterproof cover to the positive pressure chamber of the water-blocking cover 5b. The air inlet pipe runs through the top of the water-blocking cover 5b and is sealed to prevent air leakage or liquid leakage.

[0079] The air inlet pipe is connected to the positive pressure source and has a plurality of air outlets, and the air outlets of the air inlet pipe are arranged around the bottom edge of the water-blocking cover 5b.

[0080] The cleaning brush is installed in the water-proof cover 5b and is arranged around the suction port. The cleaning brush is driven by a cleaning brush driver, and the bristles of the cleaning brush can scrape the dirt on the bottom of the pool. The cleaning brush is arranged around the suction port, and the height of the cleaning brush is adjustable. The height of the cleaning brush is manually adjusted. When in use, the appropriate height is adjusted according to the state of the bottom of the pool. The cleaning brush driver is a motor that drives the cleaning brush to rotate.

[0081] The present invention proposes two specific arrangements of the cleaning brush: 1) The cleaning brush is a plurality of disc-shaped brush heads arranged around the adsorption port, and the bristles of the disc-shaped brush heads face and can be driven by the cleaning brush driver to rotate along the axis.

[0082] 2) The cleaning brush is a plurality of brush rollers arranged transversely, and the plurality of brush rollers are connected end to end and arranged around the adsorption head 5. The brush rollers can be driven to rotate by a cleaning brush driver, and the bristles at the bottom of the brush rollers move toward the adsorption head 5. The cleaning brush and the scraper have similar functions, and both can be provided at the same time, or the cleaning brush can be replaced by a scraper.

[0083] The sludge suction pipe 5a needs to suck away dirt while transmitting airflow. Therefore, the inner wall of the sludge suction pipe 5a is kept as smooth as possible, and the bending is reduced, especially the large-angle bending, to prevent dirt from being deposited in the sludge suction pipe 5a. The air inlet pipe only needs to be able to stably transmit airflow, and an ordinary hose can be used.

[0084] The enclosure 5c includes an inner layer and an outer layer, and a cavity is left between the inner layer and the outer layer. The tops of the inner layer and the outer layer are fixed at the lower edge of the water-blocking cover 5b, and the bottoms of the inner layer and the outer layer are connected and fused together. The cross section of the enclosure 5c is a cone that is wide at the top and narrow at the bottom. The bottom of the enclosure 5c is narrower and easier to deform, which is conducive to the enclosure 5c fitting the uneven pool bottom. The air inlet pipe is connected to the cavity in the enclosure 5c, and the air outlet connecting the cavity and the positive pressure cavity is provided around the inner layer. In order to reduce the liquid flowing into the bottom of the adsorption port, the bottom edge of the water-blocking cover 5b should be as close to the pool bottom as possible, because the dirt on the pool bottom will make the pool bottom uneven after deposition. If the water-blocking cover 5b is too low, its edge will scratch the dirt and push the dirt to the sides of the water-blocking cover 5b, affecting the cleaning effect; if the water-blocking cover 5b is too high, the gap between the water-blocking cover 5b and the pool bottom is too large, which will absorb a large amount of chemical solution. Therefore, the lower edge of the water shield 5b is equipped with an annular enclosure 5c, which is made of elastic and deformable material. When working, the bottom of the enclosure 5c contacts the bottom of the pool. The enclosure 5c itself is deformable and can adapt to the uneven state of the pool bottom. When the adsorption head 5 moves on the bottom of the pool, the flexible enclosure 5c will not scratch the dirt, but will slide over the top of the dirt after deformation, so that the dirt can smoothly contact the adsorption port and the cleaning brush.

[0085] In order to prevent sedimentation at the bottom of the temporary storage box 3d, a conveyor 3e is provided at the bottom of the temporary storage box 3d, and the end of the conveyor 3e is aligned with the outlet of the temporary storage box 3d. The conveyor 3e can be a screw conveyor 3e or a belt conveyor 3e.

[0086] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention. It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.
