Description

Technical Field

[0001] The invention relates to the technical field of water baths, in particular to an industrial thermal circulation water bath device. Background Art

[0002] As a core device for temperature control in industry, a water bath's core function is to achieve uniform heat transfer through the flow of a circulating medium, ensuring stable operation of the reaction system or sample at a constant temperature. Traditional water baths typically consist of a circulating pump, heater, piping system, and temperature control unit.

[0003] Due to impurity precipitation and scale formation during the thermal cycle, dirt easily accumulates at the bottom of the water bath. If not cleaned, this dirt and impurities can enter the circulating water and cause corrosion and blockage of piping, heaters, and circulating pumps. However, existing industrial thermal circulating water baths generally lack bottom cleaning capabilities, a critical bottleneck that has hindered the long-term stable operation of the equipment and industrial production efficiency. Summary of the Invention

[0004] The object of the present invention is to provide an industrial thermal circulation water bath device to solve the problems raised in the prior art.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an industrial thermal circulation water bath device, comprising a pool and a water tank, the water tank being mounted on a bracket placed beside the pool, a circulation pump and a liquid level switch being arranged above the water tank, a heating component for heating water and a thermometer for detecting the water temperature being arranged in the water tank, a heat exchange box being arranged at the bottom of the pool, a return pipe for returning hot water being arranged below the water tank, the return pipe being connected to the heat exchange box, a water inlet pipe being installed at the inlet of the circulation pump, the water inlet pipe being half immersed in water and a water inlet being arranged at the part immersed in water, and the circulation pump pumping water into the water tank. Under the weight of the water and the restraint of an external rope (one end of the rope is tied to the water inlet pipe, the other end is tied to another fixed structure outside the pool), the water inlet pipe is half-submerged in water. A circulating pump draws water from the upper layer of the pool through the water inlet pipe (not shown) and pumps it into the water tank. The heater heats the water. A valve (not shown) is installed where the water tank connects to the return pipe. Once the water is heated to the set temperature, the valve opens, allowing the hot water to flow back into the pool through the return pipe. A heat exchanger is installed in the pool. The heat exchanger is located at the bottom of the pool and connected to the return pipe. The heat exchanger returns the hot water from the bottom of the pool to the pool. The circulating pump removes the water from the upper layer, which is losing heat quickly and has low heat. The heat exchanger returns the hot water from the bottom of the pool. This circulation method ensures that the heat of the water in the pool is maintained and effectively prevents the returning hot water from losing heat quickly.

[0006] The heating component is a heater, and the number of heaters is at least two. The liquid level switch is a float type liquid level switch. The heater heats the water, and the liquid level switch monitors the water level in the water tank.

[0007] The water tank is located at either end of a drive box and a secondary box. Two guide rods are rotatably mounted between the drive box and the secondary box. Each guide rod houses an electromagnetic block, which is fitted with a sliding sleeve that mates with the electromagnetic block. Magnets are located inside the sliding sleeves. A cleaning box is located between two corresponding sliding sleeves on the two guide rods. The heat exchanger box is mounted on the cleaning box. A hydraulic drive mechanism is located inside the drive box, which causes the electromagnetic block to move axially within the guide rods. Under the influence of the magnetic field, the sliding sleeves move synchronously with the electromagnetic block. A coil is wound around the electromagnetic block, which is electrically connected to a control system (not shown) in the drive box. When the coil is energized, it generates a magnetic field that attracts the magnets inside the sliding sleeves. The hydraulic drive mechanism (not shown) drives the electromagnetic block to move, which in turn causes the sliding sleeves to move synchronously with the heat exchanger box through the cleaning box. The movement of the cleaning box removes impurities deposited at the bottom of the water tank. The movement of the heat exchanger box allows hot water to flow back to different locations within the water tank, thereby improving the efficiency of the hot and cold water exchange within the water tank.

[0008] The heat exchanger box includes a housing without end covers and side panels mounted at both ends of the housing opening. Three shaft seats are mounted below the side panels. Three gratings are rotatably mounted between the two side panels via a rotating shaft. A driven gear is mounted at each end of the rotating shaft. A rack and a rotary hydraulic cylinder that drives the rack are slidably mounted below the side panels, corresponding to the driven gear. A drive gear is mounted on the output shaft of the rotary hydraulic cylinder, and the rack meshes with the drive gear and the driven gear. The rotary hydraulic cylinder is connected to the hydraulic system in the drive box via a pipe. The rotary hydraulic cylinder drives the rack to move via the drive gear, which in turn rotates the driven gear, thereby rotating the gratings on the rotating shaft. The gratings open the heat exchanger box opening, allowing hot water to flow out of the heat exchanger box. By changing the inclination angle of the gratings, the outflow direction of the hot water is changed, allowing the hot water to flow back into the pool from different angles. When hot water is not flowing back, the three gratings cooperate to close the heat exchanger box opening.

[0009] Two rows of scrapers are symmetrically arranged below the cleaning box, with each row containing several scrapers. Each scraper has a blade at one end that does not come into contact with the pool. A discharge pipe is located below the cleaning box, between the two rows of scrapers, and is connected to the sewage pump pipe outside the pool. Under the pumping action of the sewage pump (not shown), the discharge pipe draws water from the bottom of the cleaning box, while water from other locations in the pool rapidly flows toward the bottom of the cleaning box. The flow and impact of the water draw impurities into the water, creating dirty water containing impurities. The sewage pump and discharge pipe then clear the dirty water out of the pool, effectively cleaning the pool bottom. The scrapers separate impurities that settle at the bottom of the pool, facilitating extraction by the discharge pipe.

[0010] A flushing pipe is provided on one side of the discharge pipe at the bottom of the cleaning box, one end of the flushing pipe is inclined and faces the bottom of the pool, the discharge pipe is located on one side of the inclined direction of the flushing pipe, the discharge pipe is located between the flushing pipe and the scraper, a water pump is provided in the cleaning box, a plurality of extraction ports are provided in the middle position of the bottom of the cleaning box, the inlet of the water pump is connected to the extraction port through a multi-way pipe, and the outlet of the water pump is connected to one end of the flushing pipe through a pipe; two discharge pipes and two flushing pipes are symmetrically provided on the cleaning box; the discharge pipe and the flushing pipe are both square pipe structures with one end closed, the closed end is located in the cleaning box and has an opening, the openings at one end of the two discharge pipes are connected through a multi-way pipe and connected to the sewage pump, the openings at one end of the two flushing pipes are connected through a multi-way pipe and connected to the water pump, and the width of the discharge pipe is greater than the width of the flushing pipe. By installing two flushing pipes, no matter which direction the cleaning tank moves, one flushing pipe's outlet direction is opposite to the movement direction. The water sprayed from the flushing pipe hits impurities at the bottom of the pool at an inclined angle, facilitating the removal of impurities from the pool bottom and further improving impurity cleaning efficiency. The inclined end of the flushing pipe is located below and to the side of the discharge pipe. After the water is sprayed from the flushing pipe and hits the impurities, the dirty water mixed with impurities is at the inlet of the discharge pipe and directly extracted by the discharge pipe. The extraction volume of the discharge pipe is greater than the discharge volume of the flushing pipe, preventing the dirty water from spreading in the pool. The water pump draws water from the pool that has been cleaned of impurities, ensuring that impurities do not enter the water pump.

[0011] The middle part of the scraper is rotatably connected to the cleaning box through a pin shaft, and a swing shaft is provided at one end of the scraper close to the discharge pipe, one end of the swing shaft is inserted into the interior of the cleaning box, and an arc groove is provided at the position of the swing shaft at the bottom of the cleaning box corresponding to the swing shaft, and the swing shaft slides in the arc groove, and a connecting plate is provided at the position of the arc groove inside the cleaning box, and the connecting plate covers the arc groove, and the connecting plate is rotatably connected to the swing shaft, and a driving disk for driving the connecting plate to move is provided in the cleaning box, and the driving disk is rotatably connected to the connecting plate through a support plate;

[0012] The cleaning box is equipped with two partitions, which separate the interior of the cleaning box into three chambers. The discharge pipe, flushing pipe, and water pump are all located in the central chamber. The central chamber is equipped with an independent control system, hydraulic system, and power supply system. The power supply system supplies power to the control system and hydraulic system, and the control system controls the operation of the water pump and drive disk. The drive disk is a hydraulic rotating disk. The drive disk drives the connecting plate to move back and forth, and the connecting plate drives the swing shaft to continuously reciprocate in the arc groove, thereby causing the scraper to swing in the pool. The scraper concentrates impurities at the bottom of the pool on several lines, and also scrapes hard-to-rinse impurities from the bottom of the pool during the swinging process, improving the impurity cleaning effect.

[0013] There are multiple electromagnetic blocks, sleeves, heat exchange boxes, and cleaning boxes. An axially retractable and extendable bellows-like telescopic tube is located between adjacent electromagnetic blocks and between an electromagnetic block and the closed end of a guide rod. The telescopic tube and the electromagnetic block are both perforated at their centerlines. The telescopic tube is hollow and connected to a hydraulic drive mechanism via a pipe. The closed end of the guide rod is located in a secondary box. The pipes connecting the telescopic tube to the hydraulic drive mechanism and the wires connecting the electromagnetic block to the control system pass through the perforations. The hydraulic drive mechanism draws hydraulic oil from or injects it into the telescopic tubes, causing them to retract or extend. When all the tubes extend or retract simultaneously, the tubes drive the electromagnetic blocks to move synchronously in a single direction, allowing the cleaning box to clean impurities from the pool bottom. The reciprocating movement of the cleaning box by the extension and retraction of the telescopic tubes allows for multiple cleanings of the pool bottom. Alternatively, the movement of the cleaning box allows hot water to be recirculated to different locations within the heat exchange box. When one of the telescopic tubes contracts or extends, the distance between two adjacent electromagnetic blocks is adjusted, so that the two cleaning boxes or heat exchange boxes are moved closer or farther away. When the two heat exchange boxes are moved closer, hot water is concentratedly refluxed to a certain area.

[0014] Two key slots are provided on the guide rod, and an integrated flat key is provided at the position of the sliding sleeve corresponding to the key slot, and the flat key is located in the key slot. A connecting plate is provided below the sliding sleeve, and a connecting shaft is provided on both sides of one end of the connecting plate. Two auxiliary plates are provided at each end above the cleaning box, and a slideway is provided on the auxiliary plate, and the connecting shaft is located in the slideway;

[0015] One end of the guide rod is open and located in the drive box. A gear is provided at one end of the guide rod, located in the drive box. A C-shaped drive frame is slidably mounted in the drive box. A rack is provided on the drive frame corresponding to the gear, and the rack and gear mesh to transmit power. A hydraulic cylinder is installed in the drive box, and the cylinder rod of the hydraulic cylinder is connected to the drive frame. The hydraulic cylinder is connected to the hydraulic drive mechanism pipeline. When the cleaning box needs to be raised to remove the scraper from contact with the pool bottom and to move the heat exchange box, the hydraulic cylinder pulls up the drive frame, and the gear rotates the guide rod. The two guide rods rotate in opposite directions. Driven by the sliding sleeve, the connecting plate slides in the slide, thereby raising the cleaning box. When the pool bottom needs to be cleaned, the hydraulic cylinder drive frame is lowered, causing the guide rod to rotate the sliding sleeve again. Driven by the connecting plate, the cleaning box moves downward, bringing the scraper into contact with the pool bottom.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: the water inlet pipe is half immersed in water, the circulating pump draws water from the upper layer of the pool through the water inlet pipe and pumps it into the water tank, the heater heats the water, and after the water is heated to the set temperature, the hot water flows back to the heat exchanger through the return pipe, the heat exchanger returns the hot water from the bottom of the pool to the pool, the circulating pump draws away the water with low heat loss in the upper layer of the pool that loses heat quickly, and the heat exchanger returns the hot water from the bottom of the pool. Through this circulation method, the heat of the water in the pool is guaranteed, and it is effectively guaranteed that the returned hot water will not lose heat quickly.

[0017] Under the pumping action of the sewage pump, the discharge pipe draws water from the bottom of the cleaning tank. Water from other locations in the pool quickly flows toward the bottom of the cleaning tank. Under the flow and impact of the water, impurities are drawn into the water, forming dirty water containing impurities. The sewage pump and discharge pipe clean the dirty water out of the pool, completing the cleaning of the pool bottom. The scraper swings in the pool, concentrating impurities at the bottom of the pool on several lines. At the same time, the scraper also scrapes off difficult-to-rinse impurities from the bottom of the pool during the swinging process, improving the cleaning effect of impurities.

[0041] Two rows of scrapers 9 are symmetrically arranged below the cleaning box 8, and the number of scrapers 9 in each row is several. A blade is provided at one end of the scraper 9 and does not contact the water pool 1. A discharge pipe 19 is provided between the two rows of scrapers 9 below the cleaning box 8. A flushing pipe 20 is provided on one side of the discharge pipe 19 at the bottom of the cleaning box 8. The cleaning box 8 is provided with two partitions, which separate the inside of the cleaning box 8 into three chambers. The discharge pipe 19, flushing pipe 20 and water pump are all located in the middle chamber. The middle chamber is provided with an independent control system, hydraulic system and power supply system. The power supply system supplies power to the control system and the hydraulic system, and the control system controls the operation of the water pump and the drive disk 23.

The closed end is located inside the cleaning box 8 and has an opening. The openings at one end of the two discharge pipes 19 are connected by a multi-way pipe and connected to the sewage pump. The sewage pump is located outside the pool 1. The openings at one end of the two flushing pipes 20 are connected by a multi-way pipe and connected to the water pump. The width of the discharge pipe 19 is greater than the width of the flushing pipes 20. By providing two flushing pipes 20, no matter which direction the cleaning box 8 moves, there is always a flushing pipe 20 whose water outlet direction is opposite to the movement direction. The water pump draws water from the pool 1 that has been cleaned of impurities, which ensures that impurities do not enter the water pump.

[0043] The middle part of the scraper 9 is rotatably connected to the cleaning box 8 through a pin shaft. A swing shaft 24 is provided at one end of the scraper 9 close to the discharge pipe 19. One end of the swing shaft 24 is inserted into the interior of the cleaning box 8. An arc groove is provided at the position of the swing shaft 24 at the bottom of the cleaning box 8. The swing shaft 24 slides in the arc groove. A connecting plate 25 is provided at the position of the arc groove inside the cleaning box 8. The connecting plate 25 covers the arc groove. The connecting plate 25 is rotatably connected to the swing shaft. A driving disk 23 for driving the connecting plate 25 to move is provided in the cleaning box 8. The driving disk 23 is a hydraulic rotating disk. The driving disk 23 is rotatably connected to the connecting plate 25 through a support plate.

[0044] The working principle of the present invention is as follows: the water inlet pipe is half immersed in water, the circulating pump 3 draws water from the upper layer of the pool 1 through the water inlet pipe and pumps it into the water tank 2, the heater 11 heats the water, and a valve is installed at the position where the water tank 2 is connected to the return pipe. After the water is heated to the set temperature, the valve opens, and the hot water flows back to the heat exchange box 7 through the return pipe. The heat exchange box 7 returns the hot water from the bottom of the pool to the pool 1, the circulating pump 3 draws away the water in the upper layer of the pool 1 that loses heat quickly and has low heat, and the heat exchange box 7 returns the hot water from the bottom of the pool, thereby heating the water in the pool through this circulation method.

[0045] When the bottom of the pool 1 needs to be cleaned, the hydraulic cylinder 13 drives the frame 21 downward, so that the guide rod 5 drives the sliding sleeve 6 to rotate again. Driven by the connecting plate 16, the cleaning box 8 moves downward, so that the scraper 9 contacts the bottom of the pool 1. The hydraulic drive mechanism extracts hydraulic oil from the telescopic tube 17 or injects hydraulic oil into the telescopic tube 17, causing the telescopic tube 17 to contract or extend. When all the telescopic tubes 17 extend or contract at the same time, the telescopic tube 17 drives the electromagnetic block 15 to move synchronously in one direction. Driven by the electromagnetic block 15, the sliding sleeve 6 drives the cleaning box 8 to move, so that the cleaning box 8 cleans impurities on the bottom of the pool 1. By extending or contracting the telescopic tube 17, the cleaning box 8 moves back and forth, and the scraper 9 divides the impurities deposited at the bottom of the pool 1. Under the extraction of the sewage pump, the discharge pipe 19 extracts water from the bottom of the cleaning box 8, and water at other positions in the pool 1 flows rapidly to the bottom of the cleaning box 8. Under the flow and impact of the water, impurities are drawn into the water and form dirty water containing impurities. The sewage pump and the discharge pipe 19 clean the dirty water out of the pool 1, thereby cleaning the bottom of the pool 1.

[0046] The water pump draws water from the pool 1 and pours it into the flushing pipe 20. The water sprayed from the flushing pipe 20 impacts the impurities at the bottom of the pool 1 at an inclined angle, making it easier for the impurities to separate from the bottom of the pool 1. After the water is sprayed from the flushing pipe 20 and impacts the impurities, the dirty water mixed with the impurities is at the inlet of the discharge pipe 19. The dirty water is directly extracted by the discharge pipe 19. The extraction volume of the discharge pipe 19 is greater than the discharge volume of the flushing pipe 20, so that the dirty water will not spread in the pool 1.

[0047] The driving disc 23 drives the connecting plate 25 to move back and forth, and the connecting plate 25 drives the swing shaft 24 to continuously reciprocate in the arc groove, thereby causing the scraper 9 to swing in the pool 1. The scraper 9 concentrates the impurities at the bottom of the pool 1 on several lines, and also scrapes off the impurities that are difficult to rinse from the bottom of the pool 1 during the swinging process, thereby improving the cleaning effect of the impurities.

[0048] When it is necessary to lift the cleaning box 8 so that the scraper 9 does not contact the bottom of the pool 1 and drives the heat exchange box 7 to move, the hydraulic cylinder 13 pulls up the drive frame 21, and the gear drives the guide rod 5 to rotate. The two guide rods 5 rotate in opposite directions. Driven by the sliding sleeve 6, the connecting plate 16 slides in the slide, thereby lifting the cleaning box 8.

[0049] The rotating hydraulic cylinder is connected to the hydraulic system in the drive box 12 via a pipe. The rotating hydraulic cylinder drives the rack to move via the drive gear 22, which in turn drives the driven gear 26 to rotate, thereby causing the rotating shaft to rotate the grid plate 14. The grid plate 14 opens the box opening of the heat exchange box 7, allowing hot water to flow out of the heat exchange box 7. By changing the inclination angle of the grid plate 14, the outflow direction of the hot water is changed, and the hot water is returned to the pool 1 from different angles. When the hot water is not returning, the three grid plates 14 cooperate to close the box opening of the heat exchange box 7.

[0050] When hot water needs to be refluxed in different areas, the hydraulic drive mechanism controls the telescopic tube 17 to expand or contract, the electromagnetic block 15 drives the sliding sleeve 6 to move, and the cleaning box 8 drives the heat exchange box 7 to move synchronously. The movement of the heat exchange box 7 can reflux hot water at different positions of the pool 1.

[0051] When one of the telescopic tubes 17 contracts or expands, the distance between two adjacent electromagnetic blocks 15 is adjusted so that the two heat exchange boxes 7 move closer or farther away. When the two heat exchange boxes 7 move closer, hot water is concentratedly refluxed to a certain area.
