In the using process, a heat dissipation structure of an existing closed cooling tower is optimized in a jacket type heat exchange mode, the influence of evaporation capacity reduction caused by high humidity in the cooling tower is small, and the heat dissipation effect of flowing spraying water is better compared with the mode that a water film is formed outside a hot air coil pipe in the prior art; and finally, the diameters of the heat exchange fins fixed to the outer wall of the hot air coil pipe are gradually increased in the cooling water flowing direction of the heat exchange jacket, so that the flowing speed of the cooling water in the heat exchange jacket is gradually reduced, and the cooling effect of the rear half section is improved. Spraying water falling into the water collecting tank from the filler support drops outside the heat exchange jacket to form a water film, heat of water flowing in the heat exchange jacket is further distributed more evenly, and the defect that the heat exchange effect of the rear half section of the heat exchange jacket is poorer than that of the front half section of the heat exchange jacket in the prior art is overcome.

Description

Technical Field

[0001] The invention relates to the technical field of cooling towers, in particular to a hot gas cooler for producing phosphate rock filling gelling materials. Background Art

[0002] In the prior art, anhydrous gypsum-based gelling agent slurry is mainly used for underground filling, which is like putting on a "protective coat" for the mine. It can make the filling body stronger and more stable, and can ensure that the front-line miners are safer when working. In the production process of anhydrous gypsum-based gelling agent slurry, it is necessary to cool the hot air, and the cooling tower is a device used to reduce the water temperature. It exchanges heat through the flow of water and air, and uses the principles of evaporative heat dissipation, convection heat transfer and radiation heat transfer to dissipate the waste heat generated in industry or refrigeration and air conditioning, thereby reducing the water temperature. This process is also applicable to the cooling of hot air. By introducing the hot air into the cooling tower and utilizing the working principle of the cooling tower, the temperature of the hot air can be reduced to achieve a cooling effect.

[0003] In a cooling tower, the incoming hot air has a high temperature, while the air flowing over the surface of the hot air coil has a low temperature. The heat is carried away by the air and dissipated into the atmosphere. There are three forms of heat dissipation from water to air: contact heat dissipation, evaporative heat dissipation, and radiative heat dissipation. The cooling tower mainly relies on the first two types of heat dissipation, and the radiative heat dissipation is very small and can be ignored. In addition, the main function of the filler in the cooling tower is to increase the heat dissipation, extend the residence time of cooling water, increase the heat exchange area and heat exchange amount, and ensure uniform water distribution and low ventilation resistance. The filler layer used in industrial cooling towers in the prior art is usually made of stainless steel. Although it has excellent corrosion resistance and high strength, and has a longer service life than the filler layer made of plastic, the stainless steel filler will gradually age due to the erosion of water and air during use. The scale attached to the stainless steel filler becomes the main reason affecting its heat exchange efficiency.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a hot gas cooler for the production of phosphate rock filling cementitious materials is proposed. Summary of the invention

[0007] Furthermore, an air inlet is provided at the bottom of the side of the cooling tower, and exhaust fans are embedded on both sides of the top of the cooling tower.

[0008] Furthermore, a rolling filler assembly is fixed at the middle end of the cooling tower, and the rolling filler assembly includes a filler bracket and a slag discharge port. The four corners of the filler bracket are fixed to the four bosses at the middle end of the cooling tower by bolts, and slag discharge ports are opened on both sides of the filler bracket.

[0009] Furthermore, the rolling filler assembly also includes a roller and a stainless steel filler barrel. Three rollers are rotatably installed inside the filler bracket, and a stainless steel filler barrel is coaxially fixed to the middle of the roller, and adjacent stainless steel filler barrels are gap-matched.

[0010] Furthermore, a swinging spray assembly is arranged at the top of the cooling tower, and the swinging spray assembly comprises a frame and a fixed shaft. The frame is welded and fixed to the top of the cooling tower, and a fixed shaft is fixed to the opposite surface of the bottom of the frame.

[0011] Furthermore, the swing spray assembly also includes a motor, a flywheel and a connecting pin. The motor is fixed at the middle end of the top of the frame, and the flywheel is fixedly connected to the output end of the motor, and the connecting pin is slidably fitted inside the seat hole of the flywheel disc.

[0012] Furthermore, the swing spray assembly also includes a sliding sleeve and a guide rod, the connecting pin is fixed to the outer wall of the sliding sleeve, and the sliding sleeve and the guide rod are slidably matched.

[0013] Furthermore, a spray slag removal assembly is rotatably installed in the middle of the fixed shaft, and the spray slag removal assembly includes a shaft sleeve and a connecting arm. Connecting arms are fixed at both ends of the top of the shaft sleeve, and the opposite surfaces of the connecting arms are welded and fixed to both ends of the guide rod.

[0014] Furthermore, the spray slag removal assembly also includes a through hole and a spray water interface.

[0016] The present invention provides a hot gas cooler for producing phosphate rock filling cementitious materials, which has the following beneficial effects:

[0017] 1. During the use of the present invention, the hot air generated in the production process of anhydrous gypsum-based gelling agent slurry is introduced into the hot air coil from one end of the hot air inlet and outlet, and the output end of the water pump is connected to the cooling water inlet and outlet at one end of the heat exchange jacket through a water cooling pipe, and the fully cooled spray water flows through the heat exchange jacket outside the hot air coil. The flowing water takes away the heat in the hot air by convection heat transfer to achieve cooling. The present application optimizes the heat dissipation structure of the existing closed cooling tower by the jacket heat exchange method, which is not only less affected by the high humidity in the cooling tower due to the reduced evaporation, but also has a small influence on the evaporation capacity. Compared with the prior art method of forming a water film on the outside of the hot air coil, water sprinkling has a better heat dissipation effect and can effectively improve the cooling efficiency of the hot air. Finally, the heat exchange fins fixed on the outer wall of the hot air coil gradually increase in diameter along the flow direction of the cooling water in the heat exchange jacket, so that the flow rate of the cooling water in the heat exchange jacket gradually slows down to improve the cooling effect in the rear half. The spray water droplets that fall into the water collecting pool from the filler bracket fall on the outside of the heat exchange jacket to form a water film, which further makes the heat distribution of the water flowing in the heat exchange jacket more uniform, thereby solving the prior art deficiency that the heat exchange effect in the rear half of the heat exchange jacket is worse than that in the front half.

[0018] 2. During the use of the present invention, in order to solve the problem that the scale attached to the stainless steel filling barrel in the prior art affects its heat exchange efficiency and thus limits its service life, the present application sets a swinging spray assembly, so that the atomizing nozzle can swing back and forth in the fan-shaped area to achieve uniform coverage of the spray water on the stainless steel filling barrel, thereby avoiding the spray water being concentrated in a part of the stainless steel filling barrel, which not only reduces the cooling effect of the spray water, but also aggravates the scale generation of the stainless steel filling barrel in the spraying part. In addition, a hard-bristle brush is provided in the middle of the recess at the bottom of the sleeve, and the hard-bristle brush brushes the outer edge of the stainless steel filling barrel with the reciprocating swing of the sleeve, and discharges the scale attached to the stainless steel filling barrel from the slag discharge ports on both sides of the filling bracket. Moreover, the stainless steel filling barrel rotates in the filling bracket through the rotating roller, so that the stainless steel filling barrel contacts the spray water at different contact angles, thereby avoiding the problem that the stainless steel filling layer in the prior art usually generates scale on the top layer of filling, resulting in a decrease in the overall heat exchange effect, thereby effectively improving the service life of the stainless steel filling barrel.

[0027] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following embodiments are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0028] See also Figures 1 to 4 The present invention provides a technical solution: a hot air cooler for the production of phosphate rock filling cementitious materials, comprising a cooling tower 1, an air inlet 2 is provided at the bottom of the side of the cooling tower 1, and exhaust fans 3 are embedded on both sides of the top of the cooling tower 1, a water collecting pool 4 is fixed at the bottom of the cooling tower 1, and a water pump 5 is fixed on the outside of the side of the cooling tower 1, the input end of the water pump 5 is connected to a pumping pipe 6, and the pumping pipe 6 extends into the bottom of the water collecting pool 4, one side of the output end of the water pump 5 is connected to a spray pipe 7, and the other side of the output end of the water pump 5 is connected to a water cooling pipe 8, and the cooling tower 1 is provided with a water collecting pool 4. There is a hot air coil 9, and both ends of the hot air coil 9 are connected with a hot air inlet and outlet 10, the hot air coil 9 is covered with a heat exchange jacket 11, and both ends of the heat exchange jacket 11 are fixed to the inner wall flange of the cooling tower 1, and both ends of the heat exchange jacket 11 are connected with a cooling water inlet and outlet 12, and the inlet end of the cooling water inlet and outlet 12 is connected to the water cooling pipe 8, and the outlet end of the cooling water inlet and outlet 12 corresponds to the water collecting tank 4, and the outer wall of the hot air coil 9 is fixed with a heat exchange fin 13, and the diameter of the heat exchange fin 13 gradually increases along the cooling water flow direction of the heat exchange jacket 11;

[0029] The specific operation is as follows: the input end of the water pump 5 draws water from the water collecting tank 4 through the pumping pipe 6; the output end of the water pump 5 is connected to the spray water interface 1604 through the spray pipe 7; the water is atomized and sprayed out by the atomizing nozzle 1607 and falls on the stainless steel filling barrel 1404 inside the filling bracket 1401; by extending the residence time of the water on the stainless steel filling barrel 1404, and the exhaust fan 3 sucks the dry and cold air outside the cooling tower 1 from the air inlet 2, and flows alternately in the opposite direction with the spray water, so that the water is fully cooled and falls back into the water collecting tank 4 to form a closed loop; the hot air generated in the production process of the anhydrous gypsum-based gelling agent slurry is passed into the hot air coil 9 from one end of the hot air inlet and outlet 10; and the output end of the water pump 5 is connected to the cooling water inlet and outlet 12 at one end of the heat exchange jacket 11 through the water cooling pipe 8, so that the fully cooled spray water flows through the heat exchange jacket 11 outside the hot air coil 9, and the flow The moving water takes away the heat in the hot air by means of convective heat transfer to achieve cooling. The present application optimizes the heat dissipation structure of the existing closed cooling tower 1 by means of a jacketed heat exchange method.

Finally, the heat exchange fins 13 fixed on the outer wall of the hot air coil 9 gradually increase in diameter along the cooling water flow direction of the heat exchange jacket 11, so that the flow rate of the cooling water in the heat exchange jacket 11 gradually slows down, so as to improve the cooling effect in the rear half. The spray water droplets falling into the water collection pool 4 by the filler bracket 1401 fall on the outside of the heat exchange jacket 11 to form a water film, which further makes the heat distribution of the water flowing in the heat exchange jacket 11 more uniform, thereby solving the existing technical problem that the heat exchange effect of the rear half of the heat exchange jacket 11 is poorer than that of the front half.

[0030] See also Figures 5 to 7A rolling filler assembly 14 is fixed at the middle end of the interior of the cooling tower 1.

The four corners of the filler bracket 1401 are fixed with four boss bolts at the middle end of the interior of the cooling tower 1, and slag discharge ports 1402 are opened on both sides of the filler bracket 1401. The rolling filler assembly 14 also includes a roller 1403 and a stainless steel filler barrel 1404. Three rollers 1403 are rotatably installed inside the filler bracket 1401, and a stainless steel filler barrel 1404 is coaxially fixed to the middle of the roller 1403, and the clearance between adjacent stainless steel filler barrels 1404 is matched. The top of the cooling tower 1 is provided with a swing spray assembly 15, which includes a frame 1501 and a fixed shaft 1502.

The swing spray assembly 15 also includes a motor 1503, a flywheel 1504 and a connecting pin 1505. The motor 1503 is fixed to the middle end of the top of the frame 1501, and the output end of the motor 1503 is fixedly connected to the flywheel 1504, and the connecting pin 1505 is slidably matched inside the seat hole of the flywheel 1504 disk. The swing spray assembly 15 also includes a sliding The connecting pin 1505 is fixed to the outer wall of the sliding sleeve 1506, and the sliding sleeve 1506 and the guide rod 1507 are slidably matched. The spray slag removal component 16 is rotatably installed in the middle of the fixed shaft 1502. The spray slag removal component 16 includes a sleeve 1601 and a connecting arm 1602. The connecting arms 1602 are fixed at both ends of the top of the sleeve 1601, and the opposite surfaces of the connecting arms 1602 are welded and fixed to both ends of the guide rod 1507.

The middle of the sleeve 1601 is provided with a through hole 1603, and the through hole 1603 is provided. Rotatingly matched with the middle part of the fixed shaft 1502, the side of the sleeve 1601 is connected with a spray water interface 1604, and the spray water interface 1604 is connected with the spray pipe 7, the spray slag removal component 16 also includes a notch 1605, a bristle brush 1606 and an atomizing nozzle 1607, the bottom of the sleeve 1601 is provided with a notch 1605, and a bristle brush 1606 is arranged in the middle of the notch 1605, and the bristle brush 1606 is fitted with the outer edge of the stainless steel filling barrel 1404, and the atomizing nozzles 1607 are arranged at equal intervals on both sides of the notch 1605, and the atomizing nozzles 1607 correspond to the stainless steel filling barrel 1404;

[0031] The specific operation is as follows. In order to solve the problem that the scale attached to the stainless steel filling barrel 1404 in the prior art affects its heat exchange efficiency and thus limits its service life, the present application drives the flywheel 1504 to rotate through the motor 1503 when in use, and converts the rotational motion of the flywheel 1504 into the reciprocating swing of the sleeve 1601 on the fixed shaft 1502 through the longitudinal lifting of the connecting pin 1505 located in the seat hole of the flywheel 1504 disk and the lateral sliding of the sliding sleeve 1506 on the guide rod 1507, so that the atomizing nozzle 1607 can reciprocate in the fan-shaped area to achieve uniform coverage of the spray water on the stainless steel filling barrel 1404, avoiding the spray water from being concentrated in a part of the stainless steel filling barrel 1404, which not only reduces the cooling effect of the spray water, but also aggravates Scale is generated in the stainless steel filling barrel 1404 at the spraying part. In addition, a hard-bristle brush 1606 is provided in the middle of the recess 1605 at the bottom of the sleeve 1601.

Moreover, the stainless steel filling barrel 1404 is rotated in the filling bracket 1401 through the rotating roller 1403, so that the stainless steel filling barrel 1404 contacts the spraying water at different contact angles, thereby avoiding the deficiency of the prior art that the stainless steel filling layer usually generates scale on the uppermost layer of filling, resulting in a decrease in the overall heat exchange effect, and effectively prolonging the service life of the stainless steel filling barrel 1404.

[0032] In summary, when the hot air cooler for the production of phosphate rock filling cementitious materials is used, the input end of the water pump 5 draws water from the water collecting tank 4 through the pumping pipe 6, and the output end of the water pump 5 is connected to the spray water interface 1604 through the spray pipe 7, and the water is sprayed out by the atomizing nozzle 1607 and falls on the stainless steel filling barrel 1404 inside the filling bracket 1401. By extending the residence time of water on the stainless steel filling barrel 1404, and the exhaust fan 3 sucks the dry and cold air outside the cooling tower 1 from the air inlet 2, and flows alternately in the reverse direction with the spray water, the water is fully cooled and falls back into the water collecting tank 4 to form a closed loop. During this period, the hot air generated in the production process of the anhydrous gypsum-based cementitious agent slurry is passed into the hot air coil 9 from one end of the hot air inlet and outlet 10, and the water pump 5 On the other hand, the output end is connected with the cooling water inlet and outlet 12 at one end of the heat exchange jacket 11 through the water-cooling pipe 8, and the fully cooled spray water flows through the heat exchange jacket 11 outside the hot air coil 9. The flowing water takes away the heat in the hot air through convection heat transfer to achieve cooling. The present application optimizes the heat dissipation structure of the existing closed cooling tower 1 through a jacketed heat exchange method. Not only is it less affected by the high humidity in the cooling tower 1 due to the reduced evaporation, but the flowing spray water has a better heat dissipation effect than the prior art method of forming a water film on the outside of the hot air coil 9, which can effectively improve the cooling efficiency of the hot air. Finally, the heat exchange fins 13 fixed on the outer wall of the hot air coil 9 gradually increase in diameter along the cooling water flow direction of the heat exchange jacket 11, so that the cooling water in the heat exchange jacket The flow rate in the sleeve 11 is gradually slowed down to enhance the cooling effect in the rear half, and the spray water droplets falling into the water collecting pool 4 from the filling bracket 1401 fall on the outside of the heat exchange jacket 11 to form a water film, further making the heat distribution of the water flowing in the heat exchange jacket 11 more uniform, thereby solving the prior art deficiency that the heat exchange effect in the rear half of the heat exchange jacket 11 is worse than that in the front half, and in order to solve the deficiency that the scale attached to the stainless steel filling barrel 1404 in the prior art affects its heat exchange efficiency and thus limits its service life, the present application drives the flywheel 1504 to rotate through the motor 1503 when in use, and converts the rotational motion of the flywheel 1504 into The shaft sleeve 1601 is transformed into a reciprocating swing on the fixed shaft 1502, so that the atomizing nozzle 1607 can reciprocate in the fan-shaped area to achieve uniform coverage of the spray water on the stainless steel filling barrel 1404, avoiding the spray water from being concentrated in a part of the stainless steel filling barrel 1404, which not only reduces the cooling effect of the spray water, but also aggravates the scale generation of the stainless steel filling barrel 1404 in the spraying part. In addition, a hard brush 1606 is also provided in the middle of the recess 1605 at the bottom of the shaft sleeve 1601. The hard brush 1606 brushes the outer edge of the stainless steel filling barrel 1404 with the reciprocating swing of the shaft sleeve 1601, and discharges the scale attached to the stainless steel filling barrel 1404 from the slag discharge port 1402 on both sides of the filling bracket 1401.Moreover, the stainless steel filling barrel 1404 is rotated in the filling bracket 1401 by the roller 1403, so that the stainless steel filling barrel 1404 contacts the spray water at different contact angles, thereby avoiding the disadvantage that the stainless steel filling layer in the prior art usually generates scale on the top layer of filling, which leads to a decrease in the overall heat exchange effect, and effectively prolongs the service life of the stainless steel filling barrel 1404.
