Description

Technical Field

[0001] The utility model relates to a drying device for salt production, belonging to the field of edible salt production. Background Art

[0002] The process of producing iodized ordinary edible salt includes moisture intake, brine making, crystallization, salt collection and salt washing. After the salt washing step is completed, it needs to be dehydrated and dried. The drying is generally carried out by vibration drying on a vibrating drying bed.

[0003] The vibrating drying bed, also called vibrating fluidized bed dryer, works on the principle of using a combination of vibration and hot air to dry the material. First, the material is fluidized on the drying bed through the vibration device to increase the contact area between the material and the hot air. Then, the hot air heats the material through the drying bed to evaporate the moisture in the material. At the same time, the continuous vibration of the vibration device can make the material tumble and spread continuously on the drying bed, ensuring that the material is evenly heated and ventilated. Finally, after a certain period of drying, the moisture in the material is completely evaporated to obtain a dry product.

[0004] In the process of drying edible salt, the smaller the salt particles are, the more feed quantity is needed. On the basis of the same air intake, if the feed speed is too fast, the eccentric block of the vibration motor cannot be synchronized, and the vibration net is not easy to vibrate and move forward with the edible salt, the edible salt will accumulate at this end and is particularly easy to stick together.

[0005] Therefore, the present invention provides a drying device for barbeque production which can rotate and transport materials to different distances through a material transfer device. Utility Model Content

[0006] In view of this, the purpose of the utility model is to provide a drying device for barbeque production which can rotate and transport materials to different distances through a material transfer device.

[0007] The utility model is achieved in this way:

[0008] A drying device for salt production, comprising a screw feeder, a material transfer device, and a drying box, wherein a feed port is arranged at one horizontal end of the drying box, a material transfer device is installed at the bottom end of the feed port, so as to transfer the material sent by the screw feeder to the vibration net of the drying box, and a screw feeder is arranged directly above the feed port;

[0009] The material transfer device includes a driving motor, a toggle rod, and a push plate. The driving motor is located outside the drying box and is mechanically connected to the toggle rod located below the feed.

[0010] As a further improvement, the toggle lever includes a drive head connected to an output end of the drive motor;

[0011] an extension rod extending into the rod body;

[0012] A limit plate is installed at the end of the rod body close to the driving head, and the limit plate is closely attached to the inner wall of the drying box;

[0013] The adapter connected to the inner wall of the drying box is rotatably installed at the other end of the rod body.

[0014] As a further improvement, a plurality of wedge-shaped openings are formed on the outer surface of the rod at equal distances, and the push plate is engaged with the wedge-shaped openings.

[0015] As a further improvement, the push plate includes an engaging portion and a toggle portion, the engaging portion and the toggle portion are an integrated structure, and the engaging portion cooperates with the wedge-shaped opening.

[0016] As a further improvement, the engaging portion is made of rubber material or silicone material.

[0035] Reference Figure 1-Figure 5 As shown, this embodiment provides a specific implementation method for a drying device for salt production, including a screw feeder 10, a material transfer device 20, and a drying box 40. A feed port is provided at one horizontal end of the drying box 40, and a material transfer device 20 is installed at the bottom end of the feed port to transport the material sent by the screw feeder 10 to the vibration net 30 of the drying box 40. The screw feeder 10 is provided directly above the feed port;

[0036] The material transfer device 20 includes a driving motor 201, a toggle rod 202, and a push plate 203. The driving motor 201 is located outside the drying box 40 and is mechanically connected to the toggle rod 202 located below the feed. The outer surface of the toggle rod 202 is fixed with push plates 203 of different widths by plugging. There are several push plates 203.

[0037] When the utility model feeds materials through the screw feeder 10, the materials fall into the drying box 40, and the driving motor 201 drives the toggle rod 202 to drive the push plate 203 to rotate. The push plates 203 have different widths and carry different weights of materials. On the basis of the same rotational force, they will be thrown out at different distances, and then fall on the vibration net 30, and are driven forward by the vibration net 30, and are then dried by the incoming wind and discharged from the discharge port 80. The specific structure is as follows.

[0038] Wherein, the toggle rod 202 includes a driving head 221 connected to the output end of the driving motor 201;

[0039] The extension rod 222 extends into the rod body 224, and the extension rod 222 can move flexibly in the rod body 224 to adjust the total length of the rod body 224; for example, if the extension rod 222 extends outside the drying box 40, the total length of the rod body 224 is longer, and it is more convenient to connect with the output end of the drive motor 201 and to set up the drive motor 201.

[0040] A limit plate 223 is installed at the end of the rod body 224 close to the driving head 221. The limit plate 223 is tightly attached to the inner wall of the drying box 40 without any gap. Edible salt particles will not fall into the gap to cause rotation obstruction or even jamming.

[0041] The adapter 225 rotatably connected to the inner wall of the drying box 40 is installed at the other end of the rod body 224 and rotates synchronously with the rod body 224 to make the rotation smoother.

[0042] Furthermore, a plurality of wedge-shaped openings 224-1 are equidistantly provided on the outer surface of the rod body 224, and the push plate 203 is engaged with the wedge-shaped openings 224-1. The width of the end of the wedge-shaped opening 224-1 close to the outer surface of the rod body 224 is smaller than the diameter inside the wedge-shaped opening 224-1. Once the push plate 203 is embedded in the wedge-shaped opening 224-1, it will not fall off easily.

[0043] In one specific embodiment, the push plate 203 includes an engaging portion 231 and a toggle portion 232 . The engaging portion 231 and the toggle portion 232 are integrated into one structure. The engaging portion 231 matches with the wedge-shaped opening 224 - 1 .

[0044] Furthermore, the engaging portion 231 is made of a rubber material or a silicone material, which is soft and has a shape, but also has a certain deformation ability, so that the push plate 203 can be easily inserted and removed.

[0045] In one specific embodiment, the number of the pusher plates 203 is an even number, the pusher plates 203 have the same width, two pusher plates 203 form a group, and the width of the pusher plates 203 increases in a step-like manner, which is clearer and more intuitive and also easier to process.

[0046] In one specific embodiment, the number of the pusher plates 203 is an odd number. When all the pusher plates 203 are installed on the rod body 224, they are unfolded in a spiral manner, and each step of the material throwing is different.

[0047] In one specific embodiment, the thickness L of the push plate 203 does not exceed 3 cm. When the thickness L exceeds 3 cm, the tail end of the rod body 224 will not be too heavy after the rod body 224 rotates, and the material will be easier to throw.

[0048] The utility model also includes a discharge port 80 for discharging materials at the other horizontal end of the drying box 40;

[0049] A plurality of air inlets 60 and air outlets 90 are provided at the bottom and top of the drying box 40;

[0050] The fan 50 is connected to the air inlet 60 or the air outlet 90 via a pipeline.

[0051] The utility model also includes a device which is arranged on the outer surface of the drying box 40 and is mechanically connected to the vibration net 30 .

[0052] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
