[0022] The uniform speed mechanism 5 includes a movable plate 501 movably installed between the containing box 6 and the inside of the feeding bin 2, a cross bar 502 is fixedly installed on one side of the movable plate 501, a push plate 503 is fixedly installed on one end of the cross bar 502, a spring 504 is sleeved on the outer surface of the cross bar 502, a motor 505 is fixedly installed inside the containing box 6, and a cam 506 is fixedly installed on the output shaft of the motor 505.

[0023] A support plate located on the right side of the outer surface of the movable plate 501 is fixedly installed on the inner top wall of the feed bin 2, and a baffle plate located on the left side of the outer surface of the movable plate 501 is fixedly installed on the inner top wall of the accommodating box 6. By setting the support plate and the baffle plate, it is convenient to support the movable plate 501, so that the movable plate 501 can stably move left and right between the support plate and the baffle plate.

[0024] The movable plate 501 is provided with an opening which is compatible with the bottom of the feed hopper 4, and the movable plate 501 is in contact with the bottom of the feed hopper 4. The opening is driven to overlap with the feed hopper 4 intermittently by the left and right movement of the movable plate 501, so as to achieve the purpose of quantitative feeding, avoid clogging the feed hopper 4 due to excessive feeding at one time, and at the same time improve the air-drying effect.

[0025] The air drying mechanism 3 includes a hot air blower 301 fixedly installed on the top of the feed bin 2, a connecting pipe 302 fixedly installed on the inner top wall of the feed bin 2, a plurality of air nozzles 303 are arranged at the bottom of the connecting pipe 302, and an air supply pipe is connected between the connecting pipe 302 and the hot air blower 301.

[0026] The zirconium silicate entering the feed bin 2 is preliminarily heated by the hot air blower 301 to reduce the viscosity of the zirconium silicate and prevent the zirconium silicate from sticking.

[0027] A breaking mechanism is provided inside the feed bin 2, and the breaking mechanism includes a motor 2 701 fixedly installed on the left side wall of the feed bin 2, a rotating rod 702 fixedly installed at the output shaft of the motor 2 701 and rotatably installed inside the feed bin 2, and a breaking rod 703 is installed at an equal distance on the outer surface of the rotating rod 702.

[0028] By setting up a breaking mechanism, the blocky parts of zirconium silicate can be broken up to facilitate subsequent transportation.

[0029] A motor 3 is fixedly mounted on the left side wall of the conveying device 1 , a conveying rod extending into the interior of the conveying device 1 is fixedly mounted on the output shaft of the motor 3 , and a spiral blade is arranged on the outer surface of the conveying rod.

[0030] Motor 3 drives the spiral blades to transport the zirconium silicate into the dryer.

[0031] When implementing, follow these steps:

[0032] 1) First, connect the feed hopper 4 to the external feeding device, and the silicate in the feeding device enters the interior of the feed bin 2 through the feed hopper 4;

[0033] 2) Before entering the feeding bin 2, the hot air blower 301 is first operated to generate hot air, which is then transported to the connecting pipe 302 through the air supply pipe and ejected through the multiple air nozzles 303 to increase the temperature in the feeding bin 2;

Then, the zirconium silicate enters the feed bin 2 from the feeding device at a uniform speed. Under the action of the air-drying mechanism 3, the viscosity of the zirconium silicate is reduced. At this time, the motor 2 701 drives the rotating rod 702 and the breaking rod 703 to rotate to break up the agglomerated zirconium silicate;

[0035] 4) Finally, the motor 3 drives the conveying rod and the spiral blade to rotate and convey the zirconium silicate to the interior of the dryer.

[0036] In summary, the feed auxiliary device of the zirconium silicate dryer is provided with an air drying mechanism 3 so that the hot air generated by the hot air blower 301 can enter the interior of the feed bin 2 to preliminarily heat the zirconium silicate, thereby reducing the viscosity of the zirconium silicate and avoiding sticking and affecting the feed speed.

[0037] Furthermore, by setting up a uniform speed mechanism 5, zirconium silicate can enter the interior of the feed bin 2 at a uniform speed and in a quantitative manner for air-drying, thereby improving the air-drying effect and avoiding blockage caused by excessive feeding at one time. Moreover, under the action of the breaking up mechanism, the lumps of zirconium silicate are broken up, making the conveying device 1 smoother during the conveying process.
