[0002] A circulating acid drying and cooling device is a specialized chemical equipment used for drying powdered acidic chemical reagents. It mainly consists of a drying chamber and a cooling chamber. Chinese utility model patent (patent number 201920907191.8) discloses a circulating acid drying and cooling device. This device achieves circulating cooling by installing a blower and an exhaust fan symmetrically distributed along the central axis of the cooling chamber, and simultaneously incorporating a circulation system to achieve circulating flow of the acidic powdered reagent within the cooler. However, this cooler requires an additional circulating flow channel, resulting in a relatively complex structure, and is prone to clogging when powder enters the channel. Summary of the Invention

[0003] The main purpose of this invention is to provide a circulating drying and cooling equipment, which aims to improve the drying effect while avoiding the situation of moisture and clumping during discharge.

[0004] To achieve the above objectives, the present invention proposes a circulating drying and cooling equipment, comprising:

[0005] frame;

[0006] The feeding device is installed on the frame;

[0007] A drying device, installed on the frame and located downstream of the feeding device; and

[0008] A cooling device includes a cooling tank and a stirring rod. The cooling tank is mounted on the frame and located downstream of the cooling device. The cooling tank has a cooling cavity and at least two cooling air inlets and cooling air outlets communicating with the cooling cavity. The stirring rod is disposed inside the cooling cavity and can rotate inside the cooling tank. The two cooling air inlets are arranged opposite to each other and are offset from the central axis of the cooling tank. The two cooling air outlets can discharge air opposite to each other to form a circulating airflow in the cooling cavity.

[0009] In an optional embodiment, the stirring rod includes a rod body and a drive motor, the rod body being rotatably connected to the cooling tank, and the drive motor being mounted on the cooling tank and drivingly connected to the rod body.

[0010] In an optional embodiment, the stirring rod further includes a plurality of auxiliary drying boxes, which are detachably connected to the rod body and are evenly spaced along the circumference of the rod body.

[0011] In an optional embodiment, the auxiliary drying box includes a box body and an auxiliary desiccant. The box body is detachably connected to the rod body and has a drying cavity and a plurality of through holes communicating with the drying cavity. The desiccant is disposed in the drying cavity.

[0012] In an optional embodiment, the auxiliary drying box further includes mounting screws, the box body is provided with a connecting through hole, the stirring rod is provided with a mounting threaded hole, and the mounting screws pass through the connecting through hole and the mounting threaded hole to connect the box body and the stirring rod.

[0013] In an optional embodiment, the feeding device includes a feeding hopper, a feeding pipe, and a feeding pump. The feeding pipe is installed on the frame and connected to the drying device and the feeding pump. The feeding hopper is connected to the middle of the feeding pipe.

[0014] In an optional embodiment, the feeding device further includes two rollers, which are spaced apart from each other in the feeding bin and rotate relative to the feeding bin.

[0015] In an optional embodiment, the surface of the rolling roller is recessed to form a plurality of rolling grooves, and the plurality of rolling grooves are evenly spaced along the circumference of the rolling roller.

[0016] In an optional embodiment, the bottom of the cooling tank is further provided with a discharge port that communicates with the cooling chamber.

[0017] This utility model's technical solution employs a frame, with a feeding device mounted on the frame, a drying device mounted on the frame and located downstream of the feeding device, and a cooling tank mounted on the frame and located downstream of the cooling device. The cooling tank has a cooling chamber and at least two cooling air inlets and cooling air outlets connecting to the cooling chamber. A stirring rod is disposed inside the cooling chamber and can rotate inside the cooling tank. The two cooling air inlets are arranged opposite each other and offset from the central axis of the cooling tank, and the two cooling air outlets discharge air opposite each other, so as to form a circulating airflow in the cooling chamber.

[0018] In this application, the acidic chemical powder to be dried and cooled is fed into the drying device located downstream by the feeding device. After drying by the drying device, the powder enters the cooling tank. At the same time, cold air enters through the two cooling air inlets, and the stirring rod stirs the powder simultaneously. Through continuous stirring, the powder and cold air can be more fully mixed, thereby improving the drying and cooling effect. In this application, the two cooling air inlets are arranged opposite each other and offset from the central axis of the cooling tank. When the air is discharged, a circulating airflow can be formed in the cooling chamber. This not only improves the cooling effect of the powdered acidic chemical, but also drives the stirring rod to rotate to a certain extent, making the rotation speed of the stirring rod higher and consuming less energy.

[0031] Reference Figures 1 to 5 This utility model proposes a circulating drying and acid cooling device 100.

[0032] In this embodiment of the present invention, the circulating drying and cooling equipment 100 includes a frame; a feeding device 10 installed on the frame; a drying device 20 installed on the frame and located downstream of the feeding device 10; and a cooling device 30 including a cooling tank 31 and a stirring rod 32. The cooling tank 31 is installed on the frame and located downstream of the cooling device 30. The cooling tank 31 has a cooling cavity 31a and at least two cooling air inlets 31 and cooling air outlets 31c communicating with the cooling cavity 31a. The stirring rod 32 is disposed in the cooling cavity 31a and can rotate within the cooling tank 31. The two cooling air inlets 31 are arranged opposite to each other and offset from the central axis of the cooling tank 31. The two cooling air outlets 31c can discharge air relative to each other, so that a circulating airflow is formed within the cooling cavity 31a.

[0033] Specifically, the frame (not shown) is made of metal profiles. The feeding device 10 includes a feeding bin 11, a feeding pipe 12, and a feeding pump. The feeding pipe 12 is installed on the frame by screws or welding. One end of the feeding pipe 12 is connected to the feeding pump, and the other end extends towards the drying device 20. The feeding bin 11 is connected to the middle of the feeding pipe 12 and communicates with it. The drying device 20 includes a drying tank and a desiccant placed inside the drying tank. The desiccant can be activated alumina, bone charcoal, charcoal, quicklime, etc., and can be selected according to needs. The drying tank is connected to the feeding pipe 12 and the cooling tank 31. In practical applications, the acidic chemical material to be dried and cooled enters the feeding pipe 12 through the feeding bin 11 and then sequentially enters the drying tank and the cooling tank 31 under the drive of the feeding pump.

[0034] In this application, the acidic chemical powder to be dried and cooled is fed into the drying device 20 located downstream by the feeding device 10. After drying by the drying device 20, the powder enters the cooling tank 31. At the same time, cold air enters through the two cooling air inlets 31, and the stirring rod 32 stirs the powder. Through continuous stirring, the powder and cold air can be mixed more thoroughly, thereby improving the drying and cooling effect. In this application, the two cooling air inlets 31 are arranged opposite each other and offset from the central axis of the cooling tank 31. When the air is discharged, a circulating airflow can be formed in the cooling chamber 31a. This not only improves the cooling effect of the powdered acidic chemical, but also drives the stirring rod 32 to rotate to a certain extent, making the rotation speed of the stirring rod 32 higher and the energy consumption lower.

[0035] It is understandable that the number of cooling air inlets 31 can be set to 4, 6 or 8, etc., without limitation. The cooling air inlets 31 and the cooling air outlets 31c are connected to external refrigeration equipment through pipes to input cold air into the cooling chamber 31a, and at the same time, the cooling air outlets 31c output cold air from the cooling chamber 31a to maintain the air pressure balance of the cooling chamber 31a.

[0036] In this embodiment, the stirring rod 32 includes a rod body 321 and a drive motor (not shown). Bearings are provided at both the upper and lower ends of the cooling tank 31. Both ends of the rod body 321 are respectively embedded in the bearing holes and rotatably connected to the cooling tank 31. The drive motor is connected to the rod body 321 via a pulley structure. In this application, the drive motor drives the rod body 321 to rotate via the pulley structure, achieving thorough stirring of the acidic chemical reagent by the rod body 321 and enabling more complete contact with cold air.

[0037] Furthermore, the stirring rod 32 also includes a plurality of auxiliary drying boxes 322, which are detachably connected to the rod body 321 and are evenly spaced along the circumference of the rod body 321.

[0038] Specifically, there are three auxiliary drying boxes 322. The stirring rod 32 includes three connecting plates, which are evenly spaced along the circumference of the rod body 321 and extend towards the side wall of the cooling chamber 31a. Each auxiliary drying box 322 includes a box body, an auxiliary desiccant, and mounting screws. The box body has a connecting through hole 322b, and the rod body 321 of the stirring rod 32 has a mounting threaded hole. The mounting screws pass through the connecting through hole 322b and the mounting threaded hole, connecting the box body and the stirring rod 32. The box body has a drying chamber 322c and multiple through holes 322b communicating with the drying chamber 322c. The desiccant is placed inside the drying chamber 322c. In this application, by placing a desiccant inside the box, the cooling and drying effect of the circulating drying and cooling equipment 100 can be further improved. Furthermore, by spaced the three boxes between two adjacent connecting plates, the space utilization of the stirring rod 32 is greatly improved, further enhancing the drying effect of the auxiliary drying boxes 322. Meanwhile, the box and rod 321 are detachably connected, which greatly facilitates users in replacing the desiccant.

[0039] Please see again Figure 4 The feeding device 10 also includes two rolling rollers 13, which are spaced apart in the feeding bin 11. The two rolling rollers 13 are driven by a motor and can rotate relative to the feeding bin 11. Multiple rolling grooves 13a are recessed on the surface of each rolling roller 13 and are evenly spaced along the circumference of the rolling roller 13. In this application, by providing two relatively rotating rolling grooves 13a, the acidic chemical powder can be prevented from clogging the feeding bin 11. Furthermore, by providing multiple rolling grooves 13a, the friction can be increased, thereby making the rolling of the acidic chemical powder more refined.

[0040] In this application, the bottom of the cooling tank 31 is also provided with a discharge port 31d that communicates with the cooling chamber 31a. The discharge port 31d is equipped with a switch valve (not shown in the figure). By providing the discharge port 31d, it is convenient for the operator to take out the dried and cooled acidic chemical powder.

[0041] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
