Description

Technical Field

[0001] The utility model relates to a rolling device for salt manufacturing, belonging to the field of edible salt processing equipment. 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 using a vibrating drying bed or a rotary drying furnace.

[0003] For example, the vibrating drying bed uses a vibration device to fluidize the material on the drying bed, increasing the contact area between the material and the hot air; then, the hot air passes through the drying bed to heat the material, causing the moisture in the material to evaporate; at the same time, the continuous vibration of the vibration device can cause the material to continuously roll and diffuse 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, resulting in a dry product.

[0004] In the process of drying edible salt with these two drying equipments, the smaller the salt particles are, the greater the possibility of solidification, because the larger the specific surface area, the larger the contact area between the salt particles and the air, and the easier it is to deliquesce and agglomerate. In addition, if there are many small salt particles between the large salt particles, the fine salt will repeatedly deliquesce and crystallize, causing the large salt particles to stick to each other.

[0005] Currently, rollers are used for crushing and vibration. Since there are a large number of salt blocks of different sizes, and most of the salt blocks are completely dry, there is no need to return them to the furnace for drying again, they only need to be crushed.

[0006] Therefore, the utility model provides a rolling device for salt manufacturing which can roll and convey the salt at the same time. Utility Model Content

[0007] In view of this, the purpose of the utility model is to provide a rolling device for salt manufacturing that can roll and convey at the same time.

[0008] The utility model is achieved in this way:

[0009] A rolling device for salt manufacturing, comprising a conveyor and a transmission belt on the conveyor, and a rolling unit installed at the output end of the conveyor;

[0010] The rolling unit comprises a rolling roller placed horizontally above the transmission belt; the head and tail ends of the rolling roller are mounted on the frame of the conveyor through brackets;

[0011] The horizontal end of the roller is mechanically connected to a motor so that the motor drives the roller to rotate on the bracket.

[0012] As a further improvement, the roller comprises roller bars and a main body. A plurality of roller bars are installed in grooves on the outer surface of the main body by means of plug connection, so as to realize equidistant distribution of the roller bars on the outer surface of the main body.

[0013] As a further improvement, rolling bearings are installed at the joints between both ends of the main body and the brackets.

[0014] As a further improvement, the roller bar comprises a wedge-shaped part and an arc-shaped part. The wedge-shaped part and the arc-shaped part are of an integrally formed structure, and the wedge-shaped part is installed in the groove by means of plug connection.

[0015] As a further improvement, an arched arc bar is arranged at the free end of the arc-shaped part away from the wedge-shaped part.

[0016] As a further improvement, the distance L between the end of the roller bar and the surface of the conveyor belt is 0.3 - 0.5 millimeters.

[0017] As a further improvement, a placement groove for placing a cleaning brush is formed on the side surface of the roller.

[0018] As a further improvement, the placement groove is formed at a position on the side end face of the roller deviating from the center of the circle.

[0019] The beneficial effects of the present utility model are as follows:

[0020] ① In the present utility model, materials are conveyed by a conveyor to a rolling unit, and directly output after being rolled by the rolling unit. Compared with using a crusher for crushing, this kind of rolling is not restricted by the shape and size of salt blocks. The crushed salt blocks can be directly seen and can be directly packaged.

[0021] ② The particle size of the refined edible salt of the present utility model is between 20 mesh and 40 mesh, and is directly prepared under a gap difference of 0.3 - 0.5 millimeters, reducing the number of screening and re-crushing times, and being directly output after rolling.

[0032] Embodiment 1

[0033] Reference Figures 1 - 3 and Figure 5 As shown, this embodiment provides a specific implementation manner regarding a rolling device for salt production, including a conveyor 10 and a transmission belt 20 located on the conveyor 10, and a rolling unit 40 installed at the output end of the conveyor 10;

[0034] The rolling unit 40 includes a rolling roller 402 placed horizontally above the transmission belt 20; both ends of the rolling roller 402 are supported on the frame of the conveyor 10 through brackets 403;

[0035] One end of the rolling roller 402 is mechanically connected to a motor 401, so that the motor 401 drives the rolling roller 402 to rotate on the brackets 403.

[0036] In the present utility model, the conveyor 10 conveys materials to the rolling unit 40, and after being rolled by the rolling unit 40, it is directly output. Compared with using a crusher for crushing, this rolling is not restricted by the shape and size of the salt blocks. The crushed salt blocks can be seen intuitively and can be directly packaged.

[0037] Among them, the rolling roller 402 includes rolling bars 421 and a main body 423. The number of the rolling bars 421 is several, and they are installed in grooves 425 on the outer surface of the main body 423 by a plug-in connection method, so as to realize that the rolling bars 421 are equidistantly distributed on the outer surface of the main body 423.

[0038] Further, the distance L between the end of the rolling bar 421 and the surface of the transmission belt 20 is 0.3 - 0.5 millimeters.

[0039] The particle size of refined edible salt is between 20 mesh and 40 mesh. Under the gap difference of 0.3 - 0.5 millimeters, it is directly prepared, reducing the number of screening and re - crushing times, and being directly output after rolling.

[0040] Further, the rolling bar 421 includes a wedge - shaped part 421 - 1 and an arc - shaped part 421 - 2. The wedge - shaped part 421 - 1 and the arc - shaped part 421 - 2 are of an integrally formed structure. The wedge - shaped part 421 - 1 is installed in the groove 425 by a plug - in method, and the wedge - shaped part 421 - 1 is horizontally installed along the horizontal direction of the groove 425. Once the wedge - shaped wedge - shaped part 421 - 1 is installed in the groove 425, it will not move horizontally in the radial direction. And the arc - shaped part 421 - 2 can dial the conveyed salt blocks between the rolling roller 402 and the transmission belt 20 without overflowing. The salt blocks are broken by the rotating rolling roller 402 and the gradually shortening vertical height, and the effect is better.

[0041] Furthermore, an arched arc bar 421 - 3 is provided at the free end of the arc - shaped part 421 - 2 away from the wedge - shaped part 421 - 1, so that once the arc - shaped part 421 - 2 dials the salt blocks, the salt blocks will not move out in the reverse direction.

[0042] Wherein, rolling bearings 422 are installed at the joints between both ends of the main body 423 and the bracket 403, so that during the rotation of the motor 401 driving the roller 402, the rotation is smoother without a sense of blockage.

[0043] Wherein, a placement groove 426 for placing the cleaning brush 424 is formed on the side surface of the roller 402.

[0044] Furthermore, the placement groove 426 is formed at a position deviating from the center of the side end face of the roller 402. After the crushed salt blocks become edible salt particles, they will stay on the grinding bars 421. When disassembling and replacing the grinding bars 421, the cleaning brush 424 is used to clean the edible salt particles on the surface of the grinding bars 421, which is convenient for disassembly and replacement.

[0045] As a possible specific implementation manner of the present utility model, the horizontal width of the grinding bar 421 is 3 - 8 cm. Since the widths of the grinding bars 421 are different, the sizes of the salt blocks being toggled are different. The longer the width of the grinding bar 421, the larger the volume of the salt blocks being toggled, and vice versa.

[0046] As a possible specific implementation manner of the present utility model, guiding bars 30 are provided on the frame of the conveyor 10. The number of the guiding bars 30 is 2, and they are arranged on both sides of the conveyor belt 20 to gradually guide the salt blocks in a certain direction.

[0047] Furthermore, the guiding bars 30 are rotatably connected to the frame of the conveyor 10, and the included angle between the guiding bars 30 and the frame of the conveyor 10 can be adjusted. The larger the included angle, the smaller the distance between the ends of the two guiding bars 30, and the better the aggregation effect of the salt blocks.

[0048] Embodiment 2

[0049] Please refer to Figure 4 , this embodiment is different from Embodiment 1 in that the grinding bar 421 is an integrated structure composed of a wedge-shaped portion 421 - 1 and a semi-cylinder. The wedge-shaped portion 421 - 1 fits into the groove 425 on the outer surface of the main body 423, so that the semi-cylinder is exposed. The material is conveyed by the conveyor belt 20, and then crushed by using the gap between the free end of the grinding bar 421 and the conveyor belt 20. The structure is simpler and easier to process.

[0050] The above is only the preferred implementation manner of the present utility model and is not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
