Description

Technical Field

[0001] The utility model belongs to the technical field of dryers, in particular to a device for preventing slurry overflow. Background Art

[0002] Vacuum belt dryers are commonly used for continuous drying and curing of pharmaceutical, food, and chemical liquids and solids, such as traditional Chinese medicine extracts, instant solid beverages, lithium battery raw materials, and polyphosphates. When drying liquids, the concentrated slurry is usually sprayed onto a conveyor belt using a cloth.

[0003] During the drying and evaporation process, the water in the slurry and the volatile gases released during the drying reaction evaporate and are extracted from the viscous slurry under vacuum, causing it to foam. This foaming enhances the inherent fluidity of the slurry, prompting it to flow toward the edges of the conveyor belt. As the conveyor belt operates, the slurry can easily overflow the edges of the conveyor belt. This overflow can be carried onto the driven shaft as the conveyor belt rotates, where it adheres to the driven shaft. This accumulation can eventually cause the conveyor belt to slip and become inoperable.

[0004] In the prior art, for example, the technical solution described in the patent with publication number: CN220818436U is: a belt dryer, which introduces the high-temperature gas generated by the dryer box into the water storage tank through an air pump, transfers the heat to the water in the water storage tank, thereby heating the water, and then exchanges heat with the material barrel to achieve the effect of preheating the material to be dried inside the material barrel, and recycles the heat generated during the drying process.

[0005] In existing technology, overflow is usually controlled by reducing the amount of slurry sprayed, and then stopping the machine to clean the overflow before resuming operation. These measures cannot actively prevent slurry overflow. The slurry foams and overflows under vacuum, becoming a major problem affecting the continuous and stable operation of liquid vacuum belt dryers and their full production capacity.

[0029] Example 2

[0030] This embodiment is a further refinement of the first embodiment.

[0031] like Figure 1 As shown, a heating coil is installed inside the heating plate 3, and a heating medium is injected into the heating coil. The heating coil is spirally arranged inside the heating plate 3. The heating coil includes a first medium inlet 5, a first medium outlet 9, and a coil body. The first medium outlet 9 and the first medium inlet 5 are respectively arranged on either side of the heating plate 3 and connected by the coil body.

[0032] Specifically, by injecting a heating medium into the interior of the heating coil, the heating plate 3 is heated by the heating medium, and the injected heating medium is circulated through the provided first medium outlet 9 and the first medium inlet 5 to ensure the heating effect of the heating coil.

[0033] The temperature of the slurry is maintained by arranging a heating coil inside the heating plate 3 to prevent the slurry from solidifying during transportation, thereby affecting the transportation effect of the slurry.

[0034] like Figure 1 and Figure 2 As shown, a second heating chamber is provided within the first block 2, and a third heating chamber is provided within the second block 11. Heating medium is provided in each of the second and third heating chambers. A second medium inlet 8 and a second medium outlet 6 are provided at both ends of the first block 2, communicating with both ends of the second heating chamber. A third medium inlet 10 and a third medium outlet 7 are provided at both ends of the second block 11, communicating with both ends of the third heating chamber.

[0035] Specifically, such as Figure 2 As shown, by providing a first heating chamber inside the first block 2 and connecting it to the first heating chamber via the second medium inlet 8 and the second medium outlet 6, circulation of the heating medium is achieved, maintaining the heating effect of the first block 2. By providing a second heating chamber inside the second block 11 and connecting it to the second heating chamber via the third medium inlet 10 and the third medium outlet 7, circulation of the heating medium is achieved, maintaining the heating effect of the second block 11. The first block 2 and the second block 11 are heated by the heating medium, and the slurry that flows to the areas adjacent to the first block 2 and the second block 11 is heated, so that the slurry can be quickly dried and solidified, forming an overflow layer on the side mark of the conveyor belt 4, further enhancing the effect of preventing slurry overflow.

[0036] The driving assembly includes a driving shaft 12 and a driven shaft 1 , wherein the driving shaft 12 and the driven shaft 1 are respectively arranged at two ends of the conveyor belt 4 , and the driving shaft 12 is connected to the motor to drive the conveyor belt 4 to move.

[0037] The heating medium is steam, thermal oil or hot water.

[0038] Figure 1 This is only one embodiment of the present invention. According to actual needs, the first stopper 2 and the second stopper 11 can be arranged below the entire conveyor belt 4 for transporting slurry.

[0039] In this embodiment, a specific implementation method is provided. The first stopper 2 and the second stopper 11 support the two sides of the conveyor belt 4 to form an arc, so that the conveyor belt 4 forms an arc-shaped "cofferdam". The heating medium circulates inside the first stopper 2 through the second medium inlet 8 and the second medium outlet 6, and enters the internal circulation of the second stopper 11 through the third medium inlet 10 and the third medium outlet 7. The heating medium heats the first stopper 2 and the second stopper 11, and the slurry that flows to the area adjacent to the first stopper 2 and the second stopper 11 is heated, so that the slurry can be quickly dried and solidified, forming an overflow layer on the side mark of the conveyor belt 4, further enhancing the effect of preventing slurry overflow.

[0040] The device of the present invention can effectively prevent the slurry from overflowing the edge of the conveyor belt 4, thereby improving the stable operation cycle of the conveyor belt 4. As can be seen from the above description, the above embodiment of the present invention achieves the following technical effects:

[0041] 1. Blocks are added on both sides of the heating plate 3. The blocks support the two sides of the belt under the conveyor belt 4 to form an arc, so that the conveyor belt 4 forms an arc-shaped cofferdam, which effectively prevents the flow of slurry and prevents the slurry from overflowing from the edge of the conveyor belt 4, thereby improving the stable operation cycle of the conveyor belt 4.

[0042] 2. The interior of the heating block is a hollow structure. A heating medium is provided inside the cavity heating block. The heating medium effectively heats the slurry at the edge of the conveyor belt 4 area, so that the slurry at the edge of the conveyor belt 4 is fully solidified, preventing the slurry from overflowing from the edge of the conveyor belt 4.

[0043] 3. The heating medium of the heating block circulates through the heating medium inlet and the heating medium outlet.
