Description

Technical Field

[0001] The utility model belongs to the technical field of chemical production equipment, and in particular relates to an environmentally friendly and efficient chromium-free passivating agent production device. Background Art

[0002] Traditional galvanized steel plate surface passivation mainly uses chromate. In the process of processing and producing chromium-free passivator, the raw material solution for preparing chromium-free passivator needs to be heated. After the raw material solution of chromium-free passivator reacts, the chromium-free passivator needs to be cooled for subsequent processing.

[0003] The Chinese utility model patent with announcement number CN218296430U discloses a cooling device for the production of chromium-free passivating agents, comprising a cooling box, wherein the bottom and top ends of the outer side of the cooling box are both provided with vertical nozzles, a bottom rectangular block is fixed to the bottom of the cooling box, and a transverse rotating rod and a longitudinal rotating rod are provided inside the cooling box. The utility model, through the provision of a circulation mechanism, enables the interior of the transverse rotating rod and the longitudinal rotating rod to rotate with liquid, thereby facilitating heat transfer of the chromium-free passivating agent inside the cooling box, thereby lowering the temperature of the chromium-free passivating agent inside the cooling box. The provision of the rotating mechanism enables the transverse rotating rod and the longitudinal rotating rod to better disturb the chromium-free passivating agent, thereby facilitating better contact between the transverse rotating rod and the longitudinal rotating rod and the chromium-free passivating agent, thereby better cooling and lowering the temperature of the chromium-free passivating agent.

[0004] However, the above device still has the following technical problems when actually used:

[0005] First, the above-mentioned device allows the condensate to flow through the longitudinal rotating rod and the transverse rotating rod in the cooling box, so that the condensate exchanges heat with the high-temperature raw material in the cooling box, and at the same time drives the transverse rotating rod to rotate circumferentially outside the longitudinal rotating rod to achieve the purpose of cooling. However, in this method, the condensate needs to flow through the entire longitudinal rotating rod. When the temperature of the high-temperature raw material is too high, the condensate may lose its heat exchange capacity due to excessive heat absorption when it flows through the middle section of the longitudinal rotating rod. At this time, this part of the condensate has not yet returned to the water tank for further cooling, resulting in the inability to cool the condensate when it flows in the rear section of the longitudinal rotating rod. On the one hand, this reduces the cooling and heat exchange efficiency, and on the other hand, it also slows down the reflux rate of the condensate.

[0006] 2. In addition, the above device is only equipped with a single cooling device, which cannot achieve the purpose of quickly cooling the high-temperature raw materials. Simply setting up liquid cooling will greatly extend the working time of the equipment, reduce the cooling efficiency, and increase the cost loss of the equipment. Utility Model Content

[0007] The utility model provides an environmentally friendly and efficient chromium-free passivating agent production device, which aims to solve the problem mentioned in the above background technology that the condensate in the above device needs to flow through the entire longitudinal rotating rod. When the temperature of the high-temperature raw material is too high, the condensate may lose its heat exchange capacity due to absorbing too much heat when flowing through the middle section of the longitudinal rotating rod, resulting in the inability to perform cooling treatment when flowing in the rear section of the longitudinal rotating rod. In addition, the above device cannot achieve the purpose of quickly cooling the high-temperature raw material by only setting liquid cooling, and at the same time increases energy loss.

[0008] The utility model is achieved in this way. An environmentally friendly and efficient chromium-free passivating agent production device includes: a base, on which a cooling box is fixedly installed, a liquid inlet pipe is connected to the top wall of the cooling box, and a liquid outlet pipe is connected to the bottom wall, a condensing mechanism, which has: a water tank fixedly installed on the base on one side of the cooling box, and cooling components are respectively provided on both side walls of the cooling box, the cooling components are connected to the water tank, and each of the cooling components is rotatably connected to the cooling box through a rotating component, and an air cooling component is provided on the top wall of the cooling box and connected to the inner cavity of the cooling box; in this solution, the device is rotatably provided with cooling components on both side walls of the cooling box, and the coolant flow direction of the two groups of cooling components flows from the side walls of the cooling box to the center thereof, so that each group of cooling components only needs to cool the raw materials at one side of the cooling box, avoiding the problem of the coolant circulating in the cooling box for a long time due to the inability to exchange heat, accelerating the rate at which the coolant quickly flows back to the water tank, and at the same time making full use of the coolant, thereby improving the efficiency of cooling the raw materials.

[0009] In addition, the device is also provided with an air-cooling component. When the condensing mechanism is working, the air-cooling component also introduces cold air into the cooling box. The cold air is transported through the air supply pipe and mixed into the raw materials. The rotating component stirs the raw materials so that the cold air is fully in contact with the raw materials, thereby improving the efficiency of cooling the raw materials.

[0010] Preferably, the cooling assembly includes: a mounting bracket fixedly mounted on the inner wall of the cooling box, second joints fixedly mounted on both side walls of the mounting bracket, the second joint being connected to the water tank through a return pipe, a connecting bracket fixedly mounted on the side wall of the cooling box, a first joint fixedly mounted on the connecting bracket, the first joint being connected to the water tank through a water supply pipe, and a water pump fixedly mounted on the water supply pipe, a rotating pipe being connected between the first joint and the second joint on each side, the rotating pipe being rotatably arranged between the first joint and the second joint, and a plurality of water distribution pipes being connected at equal angles on the outer wall of the rotating pipe; in this scheme, when the water pump is working, the coolant stored in the water tank will be transported to the first joint through the water supply pipe, and then transmitted to the rotating pipe connected thereto through the first joint, the rotating pipe will divert the coolant and transport it to each water distribution pipe, and the multiple water distribution pipes will allow the coolant to fully contact with the raw material to achieve the purpose of heat exchange. The coolant after heat exchange carries heat from the second joint through the return pipe into the cooling box for re-cooling for subsequent use

[0011] It should be explained that the device is also provided with a condensing device in the water tank, which is used to re-cool the coolant to achieve the purpose of reuse.

[0012] Preferably, each of the water distribution pipes is an S-shaped pipe, wherein water inlet grooves connected to the first joint and the second joint are opened in both ends of the rotating tube, and the two ends of the water distribution pipe are respectively connected to the water inlet grooves on the corresponding sides; in this scheme, the coolant transmitted by the first joint is transported to the water inlet groove in one end of the rotating tube, and then flows into each water distribution pipe through the diversion of the water inlet groove. After flowing in the water distribution pipe, the coolant enters the water inlet groove connected to the other end and flows into the second joint, and then flows back to the water tank through the return pipe connected to the second joint.

[0013] Preferably, the rotating assembly includes: a driven bevel gear is fixedly mounted on the outer side of the end portion of each rotating tube close to the first joint, and a motor is fixedly connected to the connecting frame, and a driving bevel gear is fixedly mounted on the output end of the motor, and the driving bevel gear is meshed and connected to the driven bevel gear; in this scheme, the rotating tube is rotatably arranged in a through groove opened on the side wall of the cooling box. When the motor is working, its output end rotates and drives the driving bevel gear to rotate, and the driving bevel gear controls the rotation of the driven bevel gear meshed with it. Since the driven bevel gear is fixedly mounted on the outer wall of the rotating tube, it will drive the rotating tube to rotate synchronously, and use the rotating tube to drive multiple water distribution pipes connected on its outer wall to rotate, so as to achieve the purpose of stirring the raw materials, and at the same time use the coolant flowing in the water distribution pipe to achieve the purpose of sufficient contact with the raw materials, thereby improving the cooling efficiency.

[0014] Preferably, the air-cooling component includes: an air collecting box fixedly mounted on the top wall of the cooling box, at least one exhaust fan fixedly mounted on the top wall of the air collecting box, the air inlet side of the exhaust fan facing the inner cavity of the air collecting box, and an air distribution box connected to the air collecting box is also fixedly mounted on the inner top wall of the cooling box, and a plurality of exhaust holes connected to the inner cavity of the cooling box are provided on both side walls of the air distribution box at equal intervals along its length; in this scheme, when the exhaust fan is working, it will draw outside air into the air collecting box, and then transmit it to the air distribution box connected to it through the air collecting box, and the cold air will be discharged along the multiple exhaust holes opened on the side walls of the air distribution box, and mixed into the raw materials, cooperating with the condensing mechanism to improve the cooling rate of the raw materials.

[0015] Preferably, an air supply pipe is fixedly installed on the side wall of the air distribution box corresponding to each of the exhaust holes, wherein each of the air supply pipes is arranged in contact with the cooling box, and one end of the air supply pipe is connected to the exhaust hole, and the other end extends to the bottom position in the cooling box; in this scheme, the cold air entering the air distribution box will flow into each air supply pipe through the exhaust hole, and be discharged into the raw material along the transportation of the air supply pipe. When the rotating component stirs the raw material, the cold air will be fully mixed into the raw material, and the cold air will be combined with the coolant to achieve the purpose of rapid cooling of the raw material.

Therefore, each set of cooling components only needs to cool down the raw materials on one side of the cooling box, avoiding the problem of coolant circulating in the cooling box for a long time due to the inability to exchange heat, accelerating the rate at which the coolant quickly flows back to the water tank, and at the same time making full use of the coolant, thereby improving the efficiency of cooling the raw materials.

[0034] See also Figure 1-5 The utility model provides a technical solution: an environmentally friendly and efficient chromium-free passivating agent production device, comprising: a base 1, on which a cooling box 2 is fixedly mounted, a liquid inlet pipe 21 is connected to the top wall of the cooling box 2, and a liquid outlet pipe 22 is connected to the bottom wall, a condensing mechanism 3, which comprises: a water tank 31 fixedly mounted on the base 1 on one side of the cooling box 2, and cooling components 32 are respectively provided on both side walls of the cooling box 2, the cooling components 32 are connected to the water tank 31, and each cooling component 32 is rotatably connected to the cooling box 2 through a rotating component 33, and an air-cooling component 4, which is arranged on the top wall of the cooling box 2 and is connected to the inner cavity of the cooling box 2.

[0035] Furthermore, the cooling assembly 32 includes: a mounting bracket 321 fixedly mounted on the inner wall of the cooling box 2, a second joint 322 fixedly mounted on both side walls of the mounting bracket 321, the second joint 322 being connected to the water tank 31 through a return pipe 323, a connecting bracket 324 fixedly mounted on the side wall of the cooling box 2, a first joint 325 fixedly mounted on the connecting bracket 324, the first joint 325 being connected to the water tank 31 through a water supply pipe 326, and a water pump 327 fixedly mounted on the water supply pipe 326, a rotating pipe 328 being connected between the first joint 325 and the second joint 322 on each side, the rotating pipe 328 being rotatably arranged between the first joint 325 and the second joint 322, and a plurality of water distribution pipes 329 being connected at equal angles on the outer wall of the rotating pipe 328.

[0036] Specifically, an inlet valve is fixedly installed on the water inlet pipe 21, and a liquid outlet valve is fixedly installed on the liquid outlet pipe 22. When the inlet valve is opened, the liquid outlet valve is closed, and the raw material is introduced into the cooling box 2. Conversely, when the liquid outlet valve is opened, the cooled raw material is discharged. The inlet pipe 21 and the liquid outlet pipe 22 are staggered, which can maximize the contact between the raw material and the air-cooled component 4 and the condensing mechanism 3, thereby achieving the purpose of rapid cooling.

[0037] Furthermore, each water distribution pipe 329 is an S-shaped pipe, wherein water inlet grooves 3281 connected to the first joint 325 and the second joint 322 are opened in both ends of the rotating tube 328, and both ends of the water distribution pipe 329 are respectively connected to the water inlet grooves 3281 on the corresponding sides.

[0038] Furthermore, the rotating assembly 33 includes: a driven bevel gear 331 is fixedly mounted on the outer side of the end of each rotating tube 328 close to the first joint 325, and a motor 332 is fixedly connected to the connecting frame 324, and a driving bevel gear 333 is fixedly mounted on the output end of the motor 332, and the driving bevel gear 333 is meshed and connected to the driven bevel gear 331.

[0039] Specifically, a through groove is provided on the side wall of the cooling box 2 for the rotating tube 328 to pass through. A sealed bearing is provided in the through groove, and the rotating tube 328 is rotatably connected to the sealed bearing. The sealed bearing can prevent the raw materials in the cooling box 2 from leaking along the through groove on the one hand, and can also reduce the friction of the rotating tube 328 during rotation on the other hand.

[0040] Furthermore, the air-cooling component 4 includes: an air collecting box 41 fixedly mounted on the top wall of the cooling box 2, at least one exhaust fan 42 fixedly mounted on the top wall of the air collecting box 41, the air inlet side of the exhaust fan 42 facing the inner cavity of the air collecting box 41, and an air distribution box 43 connected to the air collecting box 41 is also fixedly mounted on the inner top wall of the cooling box 2, and a plurality of exhaust holes 44 connected to the inner cavity of the cooling box 2 are provided on both side walls of the air distribution box 43 at equal intervals along its length.

[0041] Specifically, the device is also provided with a condenser (condenser plate) in the air collecting box 41. The condenser (condenser plate) is located below the exhaust fan 42. When the exhaust fan 42 is working, the outside air will be blown onto the condenser, and the air will be cooled through the condenser. The air is then blown into the air distribution box 43, and the cold air is brought into contact with the raw materials to achieve the purpose of cooling them.

[0042] Furthermore, an air supply pipe 45 is fixedly installed on the side wall of the air distribution box 43 corresponding to each exhaust hole 44, wherein each air supply pipe 45 is arranged in contact with the cooling box 2, and one end of the air supply pipe 45 is connected to the exhaust hole 44, and the other end extends to the bottom position inside the cooling box 2.

[0043] The working principle and use process of this utility model:

[0044] The raw materials are introduced into the cooling box 2 through the liquid inlet pipe, and then the output end of the motor 332 drives the rotating tube 328 to rotate through the meshing of the active bevel gear 333 and the driven bevel gear 331. The water pump 327 works to draw the coolant in the water tank 31 along the water delivery pipe 326 to the first joint 325, and then enters the water inlet groove 3281 at one end of the rotating tube 328 and flows into the water distribution pipe 329. After the coolant circulates in the water distribution pipe 329, it enters the second joint 322 along the water inlet groove 3281 at the other end of the rotating tube 328, and then flows back to the water tank 31 along the return pipe 323. When the rotating tube 328 rotates, it drives multiple water distribution pipes 329 to rotate synchronously, thereby achieving the purpose of stirring and cooling the raw materials.

[0045] In addition, the exhaust fan 42 draws the external cold air into the air collecting box 41, and then into the air distribution box 43. The cold air in the air distribution box 43 is then discharged into the air supply pipe 45 through multiple exhaust holes 44, and is discharged into the raw materials through the other end of the air supply pipe 45. The rotating component 33 is used to ensure that the cold air is fully mixed into the raw materials, thereby improving the cooling efficiency of the raw materials.
