[0025] The specific implementation of the present utility model is described in detail below with reference to the accompanying drawings.

[0026] like Figure 1 、 Figure 2 As shown, an automated drying equipment for tin particle production includes a feeding area 1, a drying area 2, a cooling area 3, a discharging area 4, which are sequentially connected and fixed on a bracket, a conveying system 5 respectively arranged in the drying area and the cooling area, and an electrical controller; the brackets of the feeding area, drying area, cooling area, and discharging area can be set separately or as a whole bracket.

[0027] The feeding area includes a draining vibration screen 12 fixed on the frame 11; the tin particles are initially drained through the vibration screen and then transported to the feeding port via a conveyor belt;

[0028] The drying area includes a drying bin 21, a heating pipe 22 and a circulating fan 23 arranged in the drying bin, and a dehumidification port 24 arranged on the top of the drying bin. Insulation layers 25 can also be provided on the upper and lower sides of the drying bin. Wind screens can be installed at the feed and discharge ports of the drying area to enhance the thermal insulation effect. For safety in use, a fan protection cover 26 is provided on the circulating fan. The heating pipes in the drying bin can be arranged in a pull-out manner to reduce the difficulty of maintenance. The material slowly passes through the drying area on the conveyor belt, and hot air is formed by the heating pipe to take away moisture. The insulation layer increases the thermal insulation effect so that the surface temperature of the object can reach about 200°C, and the humid air is discharged from the dehumidification port. Five temperature measurement zones can be set in the drying bin to monitor the temperature in the drying bin so that the temperature can be adjusted in time through the controller. Figure 3 and Figure 4 As shown, an inspection door can also be installed on the side of the drying chamber to facilitate maintenance and to deal with problems such as track jamming and bottom material falling. When maintenance is required, the inspection door can be opened through the handle 28;

[0029] The cooling zone includes a cooling tunnel 31 and cooling fans 32 respectively arranged on the upper and lower surfaces of the cooling tunnel. After drying, the tin particles enter the cooling zone for cooling and are transported to the material outlet by a conveyor chain. Cooling fans are distributed above and below the cooling zone. When the cooling fans are running, they promote air flow, forming a high-speed airflow that blows towards the tin particles and quickly removes the surface heat, prompting the internal heat to be continuously transferred to the surface, forming a heat dissipation cycle, and the temperature of the tin particles is cooled to below 50°C.

[0030] The discharging area includes a material receiving inclined plate 41 and a photoelectric sensor switch 42, which automatically stops the machine when the material is full.

[0031] The conveying system includes a conveyor belt 51, a transmission shaft 52, a drive motor 53, a frequency converter, and a drying discharge inclined plate 55. The conveying system adopts a "Y"-shaped conveyor belt with a mesh size less than 2mm. The side guards on both sides are raised by 30mm to prevent metal materials from falling. The conveying speed can be freely adjusted by using a variable speed drive. A protective plate 13 can also be provided on the outside of the transmission shaft to prevent the chain from causing harm to the operator. An emergency stop switch is provided on the protective plate to facilitate stopping the conveying in an emergency. The conveying system and the electrical controller adopt existing technologies. The electrical controller may include existing technologies such as an independent electrical box, a relay, a radiator, a heating switch, a fan start, and a temperature control program to achieve efficient operation of the equipment.

[0032] The vibrating screen, driving motor, circulating fan, cooling fan, photoelectric sensor, response switch and frequency converter are electrically connected to the electrical controller respectively.

[0033] The above-mentioned drying and cooling areas can adopt a segmented drying and cooling structure to reduce energy consumption, extend the service life of the equipment, and at the same time improve the flexibility and reliability of the production process to meet different processing requirements of the same material.

[0034] The working principle and operation of this utility model are as follows:

[0035] Tin particles with a large amount of water are put into the vibrating draining screen. The vibration frequency and vibration time are adjusted by the controller to drain a large amount of water, and then the tin particles slide from the vibrating screen outlet to the feed port. The conveying button is activated, and the tin particles are transported to the drying area by the stainless steel mesh belt. The drying temperature (below 200℃) and drying time are adjusted by the controller to achieve the required drying effect of the tin particles in a relatively short time. When the dried tin particles are transported from the drying area to the cooling area, the cooling fan is started. The strong wind generated by the cooling fan quickly cools the surface temperature of the tin particles. The cooled tin particles are transported from the cooling area to the discharge port, which is connected to the suspended vibrating screen of the production equipment through the receiving inclined plate to realize the subsequent screening and packaging of the tin particles.
