Description

Technical Field

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

[0002] The process of producing iodized ordinary edible salt includes absorbing tides, brine making, crystallization, and salt collection to obtain solar salt. In industrial production, the solar salt also needs to be washed, iodized, dried, and other steps to finally obtain refined salt, which is sorted. Solar salt is obtained directly from the salt field by sun drying, so it contains sand, grass, marine plants, etc. The marine plants mentioned here include but are not limited to kelp, seaweed, etc., which need to be fed and sorted.

[0003] In industrial production, the machines used for feeding include but are not limited to screw conveyors, belt conveyors, etc. Since solar salt is granular, its flow direction cannot be well guided during the transportation process, which makes it more likely for the material to tilt to the side. Therefore, screw conveyors are more commonly used.

[0004] However, solar salt has a high moisture content and is mixed with impurities. When batch feeding and screening are carried out, the screw conveyor pipeline is easily blocked, resulting in the inability to transport materials.

[0005] Therefore, the utility model provides a feeding device for salt manufacturing which can filter materials and adjust the inclination angle. Utility Model Content

[0006] In view of this, the purpose of the utility model is to provide a feeding device for salt manufacturing which can filter materials and adjust the inclination angle.

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

[0008] A feeding device for salt manufacturing, comprising a lifting motor, a discharge port, a spiral feeding pipe, a feeding hopper, and a bracket, wherein the spiral feeding pipe is tilted and supported on the ground by the bracket, a spiral rod is installed inside the spiral feeding pipe, the top end of the spiral rod passes through the spiral feeding pipe and is connected to the lifting motor by transmission, a feeding hopper for feeding edible salt is installed at the bottom end of the spiral feeding pipe, and an adjustment frame is placed in the feeding hopper;

[0009] The adjustment frame is installed in the feed hopper at a predetermined angle A, where the predetermined angle A is 0°-90°.

[0010] As a further improvement, the adjustment frame comprises a filter part, a receiving cavity, and an extension part, the filter part and the extension part form a curved structure, and the space between the bottom surface of the filter part and the bottom of the feed hopper is the receiving cavity;

[0011] The curved structure is installed in the feed hopper at a preset angle A with both ends thereof resting against the inner wall of the feed hopper.

[0012] As a further improvement, the filter screen portion includes a first filter screen and a second filter screen, the second filter screen is fixed to one end of the extension portion, and the first filter screen is installed above the second filter screen by snap-fitting.

[0013] As a further improvement, the aperture of the second filter screen is times larger than that of the first filter screen.

[0014] As a further improvement, the first surface of the extension portion is a straight surface with a smooth surface.

[0015] As a further improvement, the second surface of the extension portion opposite to the first surface is a curved surface.

[0016] As a further improvement, a filter plate extends from the bottom surface of the other end of the extension portion opposite to the filter screen portion, and the filter plate is provided with a plurality of feed ports.

[0017] As a further improvement, the extension portion is made of stainless steel.

[0018] The beneficial effects of the utility model are:

[0019] ① The utility model filters and blocks the problem of excessive feeding speed, which causes blockage inside the spiral feed pipe, by setting an adjustment frame. The two ends of the curved structure are against the inner wall of the feed hopper and are installed in the feed hopper at a preset angle A. The larger the preset angle A, the greater the inclination of the filter part, the worse the filtering effect of the solar salt, and the worse the blocking effect. Conversely, the smaller the inclination of the filter part, the better the filtering effect of the solar salt, and the better the blocking effect.

[0020] ② A filter plate is extended from the bottom surface of the other end of the extension part and the filter part of the utility model, and the filter plate has a plurality of feed ports, which plays a role of secondary filtration and further blocks the material from entering the spiral feed pipe.

[0021] ③ The utility model can also install a vibration motor at the bottom of the feed hopper to vibrate the feed hopper and simultaneously coordinate resonance with the spiral feed pipe to assist feeding.

[0022] ④ The length ratio of the filter part and the extension part of the utility model is 2:1, which increases the filtering effect of the filter part 701 and does not affect the feeding of the extension part. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0032] Reference Figure 1-Figure 6 As shown, this embodiment provides a specific implementation method for a feeding device for salt manufacturing, including a lifting motor 10, a discharge port 20, a spiral feeding pipe 30, a feeding hopper 40, and a bracket 50. The spiral feeding pipe 30 is tilted and supported on the ground by the bracket 50. A spiral rod 60 is installed inside the spiral feeding pipe 30. The top end of the spiral rod 60 passes through the spiral feeding pipe 30 and is transmission-connected to the lifting motor 10.

[0033] See also Figure 2 As shown, when the lifting motor 10 of the utility model drives the screw rod 60 to rotate, due to the gravity of the material and the friction between the material and the trough wall, the material can only move forward along the bottom of the conveyor trough under the push of the blades until the material is discharged from the discharge port 20;

[0034] A feed hopper 40 for feeding edible salt is installed at the bottom end of the spiral feeding pipe 30, and an adjustment frame 70 is arranged in the feed hopper 40. The adjustment frame 70 is installed in the feed hopper 40 at a predetermined angle A, and the predetermined angle A mentioned here is 0°-90°.

[0035] The utility model sets an adjustment frame 70 to filter and prevent the problem of excessive feeding speed causing blockage inside the spiral feeding pipe 30. The specific structure and principle are as follows:

[0036] The adjustment frame 70 includes a filter part 701, a receiving cavity 702, and an extension part 704. The filter part 701 and the extension part 704 form a curved structure. The space between the bottom surface of the filter part 701 and the bottom of the feed hopper 40 is the receiving cavity 702.

[0037] The curved structure has both ends pressed against the inner wall of the feed hopper 40 and is installed in the feed hopper 40 at a preset angle A. The larger the preset angle A is, the greater the inclination of the filter part 701 is, the worse the filtering effect of the solar salt is, and the worse the blocking effect is. Conversely, the smaller the inclination of the filter part 701 is, the better the filtering effect of the solar salt is, and the better the blocking effect is.

[0038] When the preset angle A is smaller, the material is poured into the feed hopper 40 from above the feed hopper 40 and falls on the filter part 701. The filter part 701 plays a filtering role, and the impurities in the solar salt are filtered out. The filtered solar salt will fall into the interior of the spiral feed pipe 30 from the accommodating cavity 702.

[0039] When the preset angle A is larger, the material is poured into the feed hopper 40 from above the feed hopper 40 and falls on the filter part 701. Since the filter part 701 is arc-shaped and mesh-shaped, it will block the flocs in the solar salt, such as seaweed and other plants, from entering the spiral feed pipe 30 and entangled on the spiral rod 60, causing blockage.

[0040] like Figure 5 As shown, further, the filter part 701 includes a first filter 711 and a second filter 712, the second filter 712 is fixed to one end of the extension part 704, and the first filter 711 is installed above the second filter 712 by snap-fitting.

[0041] Moreover, the aperture of the second filter 712 is 2 times larger than that of the first filter 711. Once the solar salt passes through the first filter 711, it will not be blocked by the second filter 712. The second filter 712 does not have a strong filtering effect, but only has a screening effect.

[0042] In one specific embodiment, the first surface 741 of the extension portion 704 is a straight surface with a smooth surface, so that materials can pass through smoothly without getting stuck in the extension portion 704 .

[0043] In one specific embodiment, the second surface 742 of the extension portion 704 opposite to the first surface 741 is a curved surface, and the material will not adhere to the second surface 742, so that the material can pass smoothly without residue.

[0044] Furthermore, a filter plate 703 is extended from the bottom surface of the other end of the extension portion 704 opposite to the filter screen portion 701 . The filter plate 703 has a plurality of feed ports to perform secondary filtration and further block materials from entering the spiral feed pipe 30 .

[0045] As a possible specific implementation of the present invention, the extension portion 704 is made of stainless steel. During the preparation process, the stainless steel is resistant to hydrochloric acid and is easy to process.

[0046] like Figure 6 As shown, as a possible specific implementation of the utility model, a vibration motor 80 can also be installed at the bottom of the feed hopper 40 to vibrate the feed hopper 40 and simultaneously coordinate the resonance of the spiral feed pipe 30 to assist in feeding.

[0047] As a possible specific implementation of the present invention, the length ratio of the filter part 701 and the extension part 704 is 2:1, which increases the filtering effect of the filter part 701 and does not affect the feeding of the extension part 704.

[0048] 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.
