Description

Technical Field

[0001] This utility model relates to the field of laundry detergent production technology, specifically a cooling device for laundry detergent after heat drying. Background Technology

[0002] In the production of laundry detergent, spray drying is a key process for obtaining granular finished products. The laundry detergent granules that come out of the high-temperature drying tower are at a high temperature. If they are packaged directly, they are prone to clumping due to heat accumulation, affecting the product's flowability, and may also damage the packaging materials. Therefore, hot laundry detergent needs to be cooled before packaging.

[0003] Currently, the most common cooling method for drying laundry detergent is to use a cold air unit. During the detergent conveying process, a large flow of cold air is used to blow the detergent away to remove its heat and cool it down after drying.

[0004] However, the air-blowing cooling method has problems such as short contact time between cold air and powder, uneven heat exchange, and limited cooling efficiency. During the transportation process, the cold air comes into contact with the surface of the laundry detergent more, which can easily lead to the laundry detergent being too thick and the cooling effect being poor. Utility Model Content

[0005] The purpose of this invention is to provide a cooling device for laundry detergent after hot drying, so as to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solutions: A cooling device for laundry detergent after heat drying includes an inclined conveyor frame, a slide for carrying and guiding laundry detergent at the top of the conveyor frame, a cooling cavity inside the conveyor frame located below the slide, a serpentine cooling pipe inside the cooling cavity, and water inlet and outlet of the serpentine cooling pipe extending to the outside of the conveyor frame; an air inlet at one end of the cooling cavity and an air outlet at the other end; and an axial flow fan on the conveyor frame for blowing air to the air inlet.

[0007] Preferably, the cooling cavity is further provided with an auxiliary heat conduction structure to enhance heat conduction, which is connected between the serpentine cooling pipe and the inner top wall of the cooling cavity.

[0008] Preferably, the auxiliary heat-conducting structure includes a heat-conducting metal block fixed on the serpentine cooling pipe and a heat-conducting copper sheet connected between the heat-conducting metal blocks, the top of which is bonded to the inner top wall of the cooling cavity by heat-conducting adhesive.

[0009] An adjustable height limiter is provided above the slide to control the thickness of the laundry detergent as it flows through the slide. A horizontal connecting plate is fixedly connected to the top of the limiter.

[0010] The limiting plate is connected to a vertical adjustment mechanism, which includes a fixed block fixed to the conveyor frame. An adjusting screw and a locking nut that cooperate with the adjusting screw are fixedly connected to the fixed block. The height of the horizontal connecting plate and the limiting plate is set by adjusting the position of the locking nut.

[0011] Preferably, the axial flow fan is fixed to the conveyor frame by a support frame and aligned with the air inlet of the cooling cavity. The air outlet is a ventilation opening opened on the side wall of the conveyor frame, and the air inlet is an opening that is open at one end of the cooling cavity.

[0012] The beneficial effects of this utility model are: This invention conveys dried laundry detergent through a slide. During conveying, a limiting plate restricts the thickness of the detergent. In the process of conveying the detergent, a serpentine cooling pipe in the lower cooling cavity is used for heat exchange, which quickly cools the detergent. An axial flow fan blows air to achieve interaction between the cooling cavity and the outside air, carrying away some of the heat in the cooling cavity and effectively improving the cooling effect on the detergent.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figures 1-4 As shown, a cooling device for laundry detergent after hot drying includes an inclined conveyor frame 1. The top of the conveyor frame 1 is a concave slide 101. The outlet of the laundry detergent drying device is located above the higher end of the conveyor frame 1. Below the lower end of the conveyor frame 1, there is an external conveyor belt that can directly drop the dried laundry detergent onto the conveyor frame 1 and slide it down the slide 101 to the lower conveyor belt, which then transports it to the subsequent packaging mechanism.

[0017] A cooling mechanism is provided on the conveyor frame 1. The cooling mechanism includes a cooling cavity 201, which is opened on the conveyor frame 1 and located below the slide 101. A serpentine cooling pipe 202 is fixedly connected to the top of the inner wall of the cooling cavity 201. The inner wall of the slide 101 is made of heat-conducting metal material to improve the heat exchange capacity between the laundry detergent above the slide 101 and the serpentine cooling pipe 102, thereby cooling the laundry detergent passing through the slide 101.

[0018] Both ends of the serpentine cooling pipe 202 pass through the conveyor frame 1 and extend to the outside of the conveyor frame 1. The two ends of the serpentine cooling pipe 202 located outside the conveyor frame 1 are designed as an inlet 203 and an outlet 204, respectively. The inlet 203 is connected to the external water inlet pipe, and the outlet 204 is connected to the external water outlet pipe. After the water in the outlet pipe is condensed by the external equipment, it is transported back to the inlet 203 by the water pump in conjunction with the inlet pipe.

[0019] Thermally conductive metal blocks 205 are fixedly connected to both sides of the outer surface of the serpentine cooling pipe 202. Thermally conductive copper sheets 206 are fixedly connected between the thermally conductive metal blocks 205. The top of the thermally conductive copper sheet 206 and the inner wall of the cooling cavity 201 are bonded together with thermally conductive adhesive, which can further improve the heat exchange capacity between the detergent above the slide 101 and the serpentine cooling pipe 102.

[0020] The cooling cavity 201 has an open design at the high end and a closed design at the low end. Ventilation openings 3 are provided on both sides of the conveyor frame 1 at the low end, and the ventilation openings 3 are connected to the cooling cavity 201. An axial flow fan 4 is installed on the outer side of the opening end of the slide 101. Support frames 401 are fixedly connected to both sides of the axial flow fan 4. The support frames 401 are fixed on the conveyor frame 1 to provide support for the axial flow fan 4. The axial flow fan 4 sends air into the cooling cavity 201. Some of the airflow can pass through the cooling cavity 201 and carry away some of the heat from the serpentine cooling pipe 202. This not only improves the heat dissipation effect of the serpentine cooling pipe 202 on the slide 101, but also reduces the condensation pressure of the cooling water output from the serpentine cooling pipe 202.

[0021] The conveyor frame 1 is equipped with a limiting mechanism, which includes a limiting plate 501 with adjustable height. The limiting plate 501 is located above the slide 101. When the laundry detergent passes through the slide 101, it can only pass through the space below the limiting plate 501 in the slide 101, so as to avoid the laundry detergent accumulating too thickly when passing through the slide 101, which would affect the cooling capacity of the dried laundry detergent. A transverse connecting plate 502 is fixedly connected to the top of the limiting plate 501. Fixed blocks 503 are fixedly connected to both sides of the conveyor frame 1. An adjusting screw 504 is fixedly connected to the top of the fixed block 503. The adjusting screw 504 passes through both ends of the transverse connecting plate 502. Locking nuts 505 are threadedly connected to the adjusting screw 504 above and below the transverse connecting plate 502. By adjusting the height of the locking nuts 505, the height of the transverse connecting plate 502 can be adjusted, thereby controlling the up and down movement of the limiting plate 501, and thus adapting to the passage capacity of laundry detergent with different heat dissipation requirements in the slide 101.

[0022] The working principle of the cooling device after hot drying of laundry detergent provided by this utility model is as follows: When the dried laundry detergent needs to be cooled, the dried laundry detergent is fed into the upper part of the slide 101 and flows down the slope of the slide 101. After passing the bottom of the limiting plate 501, the thickness of the laundry detergent flowing on the slide 101 is limited, and finally it flows into the conveyor belt below and is transported to the next processing stage. External cooling water is input into the interior of the serpentine cooling pipe 202 through the inlet 203. The heat exchange between the serpentine cooling pipe 202 and the conveyor frame 1 is utilized. At the same time, the heat-conducting metal block 205 and the heat-conducting copper sheet 206 conduct heat together, improving the heat exchange efficiency. As the laundry detergent passes through the slide 101, the laundry detergent above is cooled. After the cooling water exchanges heat through the serpentine cooling pipe 202, it is output to the external pipe through the outlet 204. During the heat exchange process, the axial flow fan 4 is started, and the airflow passes through the interior of the cooling cavity 201 and finally flows out through the vent 3, taking away some of the heat in the cooling cavity 201 and enhancing the cooling capacity of the serpentine cooling pipe 202 in the cooling cavity 201 for the dried laundry detergent.

[0023] Compared with related technologies, the cooling device for laundry detergent after heat drying provided by this utility model has the following beneficial effects: This invention conveys dried laundry detergent through a slide 101. During conveying, a limiting plate 501 restricts the thickness of the laundry detergent. During the conveying process, heat exchange is performed using a serpentine cooling pipe 202 in the lower cooling cavity 201 to cool the laundry detergent in the slide 101. This quickly cools the laundry detergent. Furthermore, an axial flow fan 4 blows air to achieve interaction between the cooling cavity 201 and the outside air, carrying away some of the heat in the cooling cavity 201 and effectively improving the cooling effect on the laundry detergent.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
