[0003] However, existing drying and granulation equipment is still not ideal in practical use. This is because the fan equipment used to heat and dry fine droplets has a limited curing range for the fine droplets, which easily leads to a decrease in thermal efficiency and thus affects the drying speed of the fine droplets. In order to solve the above problems, the inventors propose a countercurrent pressure spray drying and granulation equipment. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figure 1-3 As shown, this utility model provides a technical solution: a counter-current pressure spray drying granulation device, including a drying tower 1, a feed pipe 11 fixedly installed at the top of the drying tower 1, a booster pump 12 fixedly installed inside the feed pipe 11, an atomizer 13 fixedly connected to one end of the booster pump 12, a solenoid valve 14 fixedly installed at the bottom of the drying tower 1, symmetrically distributed rotating shafts 15 rotatably inserted inside the drying tower 1, fixing blocks 16 fixedly sleeved on the outer side of each rotating shaft 15, an L-shaped fan 17 fixedly connected to one end of each fixing block 16, a half gear 18 fixedly connected to one end of each rotating shaft 15, a cylinder 19 fixedly installed on the outer side of the drying tower 1, a connecting rod 20 fixedly connected to the driving end of the cylinder 19, symmetrically distributed toothed plates 21 fixedly installed on the outer side of the connecting rod 20, one end of the toothed plate 21 meshing with the corresponding half gear 18, and symmetrically distributed air inlets 22 opened on the outer side of the drying tower 1.

[0020] A filter plate 23 is movably snapped onto the inner side of the air inlet 22. A horizontal plate 24 is fixedly connected to the outer side of the filter plate 23. An array of positioning blocks 25 is fixedly installed on the outer side of the drying tower 1. One end of the horizontal plate 24 is slidably sleeved onto the outer side of the corresponding positioning block 25. A symmetrically distributed connecting block 26 is fixedly installed on the outer side of the horizontal plate 24. A bolt 27 is threaded onto one end of each positioning block 25. One end of the bolt 27 is threaded onto the inner side of the connecting block 26.

[0021] By adopting the above technical solution, the filter plate 23 is used to help the air inlet 22 filter the air and prevent dust and materials from adhering to it. The filter plate 23 is positioned by the horizontal plate 24 on the positioning block 25, and then the filter plate 23 is fixed by the bolts 27 installed in the connecting block 26. The bolts 27 are removed and the horizontal plate 24 is removed from the positioning block 25, which makes it easy to disassemble the filter plate 23 and facilitates the cleaning and maintenance of the filter plate 23 in the future.

[0022] A slider 28 is fixedly installed at one end of the connecting rod 20, and a groove 29 is provided on the front of the drying tower 1. One end of the slider 28 is slidably engaged with the inner side of the groove 29.

[0023] By adopting the above technical solution, the movement stability of the connecting rod 20 and the toothed plate 21 is improved by setting the slider 28 to slide in the groove 29.

[0024] Symmetrically distributed triangular plates 30 are fixedly installed on the inner bottom surface of the drying tower 1.

[0025] By adopting the above technical solution, setting the triangular plate 30 facilitates material discharge.

[0026] A handle 31 is fixedly installed at the middle of one end of each horizontal plate 24.

[0027] By adopting the above technical solution, the handle 31 can be used to easily pull the horizontal plate 24 and the filter plate 23 out of the air inlet 22.

[0028] The bottom surface of the drying tower 1 is fixedly equipped with arrayed support legs 32.

[0029] By adopting the above technical solution, the drying tower 1 is supported by setting support legs 32.

[0030] Working principle: First, the liquid material is poured into the drying tower 1 through the feed pipe 11. After entering the feed pipe 11, the liquid material is pressurized by the booster pump 12 and discharged. Then, it passes through the atomizer 13 and becomes fine droplets. The fine droplets drip from top to bottom inside the drying tower 1. At the same time, the L-shaped fan 17 is started to heat the fine droplets by blowing air from bottom to top, drying them into granules. Then, the cylinder 19 is controlled to reciprocate to push the connecting rod 20 up and down. The movement of the connecting rod 20 drives the toothed plate 21 to move. The toothed plate 21 then controls the half gear 18 to reciprocate. The half gear 18 drives the rotating shaft 15 and the L-shaped fan 17 to operate. The movement expands the counter-current drying range of the L-shaped fan 17, which helps to improve thermal efficiency, make fuller use of heat energy, and achieve faster drying speed. When air enters the drying tower 1, the filter plate 23 helps the air inlet 22 to filter the air and prevent dust from contaminating the material. The filter plate 23 is positioned by the horizontal plate 24 on the positioning block 25, and then the filter plate 23 is fixed by the bolts 27 installed in the connecting block 26. The bolts 27 are removed to detach the horizontal plate 24 from the positioning block 25, which makes it easy to disassemble the filter plate 23 and facilitates the cleaning and maintenance of the filter plate 23 in the later stage.

[0031] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
