Description

Technical Field

[0001] This utility model relates to the field of corn starch processing technology, and in particular to a multi-stage separation and screening mechanism for corn starch production and processing. Background Technology

[0002] The production method of corn starch includes steps such as cleaning, soaking, coarse crushing of corn, germ separation, corn grinding, starch sieving, protein separation and drying, centrifugation and drying. In the starch sieving process, the conventional method is to grind the corn pieces to obtain corn paste, and then use sieving to separate the starch from the coarse and fine residue.

[0003] In the prior art, referring to a corn starch screening device with patent application number 2022209387467, when screening corn starch, the starch and coarse and fine residue mixture is directly poured into the screening equipment for screening. The pouring process causes dust, and the screening structure is a nested inclined setting. The corn starch and coarse and fine residue mixture accumulates at the bottom of the nested cylinder screen under its own weight. Therefore, it is impossible to complete the rapid screening by vibration alone, and it is difficult to achieve layered separation of coarse and fine residue. The coarse and fine residue cannot be used directly after subsequent separation.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a multi-stage separation and screening mechanism for corn starch production and processing, in order to solve the problem that corn starch and coarse and fine residue mixtures cannot be quickly screened and separated separately under their own weight.

[0006] The objective of this utility model can be achieved through the following technical solution: A multi-stage separation and sieving mechanism for corn starch production and processing includes a side box and sieving plates. The sieving plates are distributed from top to bottom on the inner side of the side box, and a screen is installed in the middle of the sieving plates. The screen aperture of the screen gradually decreases from top to bottom. A discharge rod seat is installed on one side of each sieving plate. A vibration motor is installed outside the discharge rod seat. A discharge bag penetrating the side box is installed at the outer end of the discharge rod seat. A top cover is installed at the upper end of the side box. An inlet pipe is installed in the middle of the upper end of the top cover. A conveying shovel is installed at the upper end of the inlet pipe. An insert rod is installed in the middle of the upper end of the conveying shovel near the inlet pipe.

[0007] Preferably, an inner ring screen plate and an outer ring screen plate are installed sequentially from the inside to the outside at the inner bottom end of the screening plate. The inner ring screen plate and the outer ring screen plate are on the same horizontal plane as the screen mesh, and the screen hole diameter of each set of inner ring screen plates and outer ring screen plates gradually decreases from top to bottom.

[0008] Preferably, the discharge rod seat has a discharge port inside the outer ring screen plate that communicates with the discharge bag.

[0009] Preferably, each of the screening plates is provided with a fixing plate at intervals on its outer ring side, and a connecting block connected to the inner wall of the side box is installed on the outer side of the fixing plate.

[0010] Preferably, the portion of the infeeding shovel corresponding to the feed pipe has a slot, and the insert rod is located on the inner ring side of the slot.

[0011] Preferably, the bottom of the side box is equipped with a bottom rod that contacts the ground, and the side box has an insertion hole that matches the discharge bag.

[0012] The beneficial effects of this utility model are:

[0013] (1) In this utility model, after corn starch and coarse and fine residues are fed into the side box, they first gather in the upper screening plate and are gathered in the center. Under the synchronous start of the vibrating motor, the mixture in each screening plate can be screened step by step. The screening process is completed by the vibration effect of the vibrating motor, and the coarse and fine residues are separated and discharged into the discharge bag through the discharge port. The corn starch passes through each set of screens, the inner screen plate, and the outer screen plate in sequence and is screened downwards, and is collected at the bottom of the entire separation and screening mechanism. The advantage is that the screening stage of corn starch and coarse and fine residues eliminates the influence of the weight of the mixture of corn starch and coarse and fine residues, which causes incomplete separation, and can achieve accurate multi-stage separation.

[0014] (2) The corn starch and coarse and fine residue mixture is first fed into the screening box through the feeding component from the packaging bag. During the feeding, the packaging bag is supported by the feeding shovel, while the upper part of the packaging bag is supported by the insert rod. The opening of the packaging bag is completely buried in the slot, so that the corn starch and coarse and fine residue mixture in the packaging bag can slide down smoothly. The dust generated during the feeding process is all collected in the packaging bag, and no dust will be generated. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: This example is used to solve the problem that corn starch and coarse and fine residue mixtures cannot be quickly screened and separated under their own weight.

[0025] Please see Figure 1 - Figure 6 As shown, this embodiment is a multi-stage separation and sieving mechanism for corn starch production and processing, including a side box 1 and screening plates 6. The screening plates 6 are distributed from top to bottom on the inner side of the side box 1, and a screen 7 is installed in the middle of the screening plate 6. The screen aperture of the screen 7 gradually decreases from top to bottom. A discharge rod seat 9 is installed on one side of each screening plate 6. A vibration motor 10 is installed outside the discharge rod seat 9, and a discharge port penetrating the side box 1 is installed at the outer end of the discharge rod seat 9. The bag 11 and the screening plate 6 have an inner ring screen plate 16 and an outer ring screen plate 17 installed sequentially from the inside to the outside. The inner ring screen plate 16 and the outer ring screen plate 17 are on the same horizontal plane as the screen 7, and the screen aperture of each set of inner ring screen plates 16 and outer ring screen plates 17 gradually decreases from top to bottom. The screening plate 6, the screen 7, and the inner ring screen plate 16 and the outer ring screen plate 17 together constitute a screening component to achieve accurate and separate separation of corn starch and coarse and fine residue mixture.

[0026] The discharge rod seat 9 has a discharge port 14 that communicates with the discharge bag 11 inside the outer ring screen plate 17. Each screening plate 6 has a fixing plate 12 installed at intervals on the outer ring side. The fixing plate 12 has a connecting block 13 that connects to the inner wall of the side box 1 installed on the outside of the fixing plate 12.

[0027] Please see Figure 1 - Figure 5 As shown, after corn starch and coarse and fine residues are fed into the side box 1, they first gather in the upper screening plate 6 and are gathered in the center. Under the synchronous start of the vibrating motor 10, the mixture in each screening plate 6 can be screened step by step. The screening process is completed by the vibration effect of the vibrating motor 10, and the coarse and fine residues are separated and discharged into the discharge bag 11 through the discharge port 14. The corn starch passes through each set of screens 7, the inner ring screen plate 16, and the outer ring screen plate 17 in sequence and is screened downwards, and is collected at the bottom of the entire separation and screening mechanism.

[0028] In this process, the screening stage of corn starch and coarse and fine residues eliminates the incomplete separation caused by the weight of the mixture of corn starch and coarse and fine residues, thus achieving accurate multi-stage separation.

[0029] Example 2: This example is used to solve the dust problem that occurs when feeding corn starch and coarse and fine residue mixture.

[0030] Please see Figure 1 - Figure 4 and Figure 6 As shown, a multi-stage separation and screening mechanism for corn starch production and processing in this embodiment includes a top cover 2 installed on the upper end of a side box 1, a feed pipe 3 installed in the middle of the upper end of the top cover 2, a conveying shovel 4 installed on the upper end of the feed pipe 3, and an insert rod 5 installed near the middle of the upper end of the conveying shovel 4. The conveying shovel 4 and the insert rod 5 together constitute a feeding assembly, which realizes the loading and feeding of a mixture of corn starch and coarse and fine residue, avoiding dust generation.

[0031] The part of the inlet pipe 3 corresponding to the inlet shovel 4 has a slot 18, and the insertion rod 5 is located on the inner ring side of the slot 18. The bottom of the side box 1 is equipped with a bottom rod 8 that is in contact with the ground, and the side box 1 has an insertion hole 15 that matches the discharge bag 11.

[0032] Please see Figure 3 , Figure 4 and Figure 6 As shown, the corn starch and coarse and fine residue mixture is first fed into the screening box from the packaging bag through the feeding component. During the feeding process, the feeding shovel 4 provides overall support for the packaging bag, while the upper part of the packaging bag is supported by the insert rod 5. The opening of the packaging bag is completely buried in the slot 18, which allows the corn starch and coarse and fine residue mixture inside the packaging bag to slide down smoothly. Moreover, all the dust generated during the feeding process is collected in the packaging bag, and no dust is generated.

[0033] Combining Embodiment 1 and Embodiment 2, on the one hand, the multi-level screening components accurately separate corn starch from coarse and fine residues, eliminating the incomplete screening caused by the weight of the mixed materials; on the other hand, the bag opening support structure in the feeding component ensures smooth feeding of the mixed materials, and most importantly, avoids dust generation. The combined use of these two components can effectively separate coarse and fine residues and finished products in the corn starch processing process, improving screening efficiency.

[0034] Example 3: The process and principle of this utility model are as follows:

[0035] Step 1: The mixture of corn starch and coarse and fine residue is first fed into the screening box through the feeding component from the packaging bag. During the feeding, the packaging bag is supported by the feeding shovel 4, while the upper part of the packaging bag is supported by the insert rod 5, and the opening of the packaging bag is completely buried in the slot 18.

[0036] Step 2: After the corn starch and coarse and fine residue are poured into the side box 1, they first gather in the upper screening plate 6 and gather in the center.

[0037] Step 3: Under the synchronous start of the vibrating motor 10, the mixture in each layer of the screening plate 6 can be screened step by step. The screening process is completed by the vibration effect of the vibrating motor 10, and the coarse and fine residues are separated and discharged into the discharge bag 11 through the discharge port 14. The corn starch passes through each set of screens 7, the inner ring screen plate 16, and the outer ring screen plate 17 in sequence and is screened downwards.

[0038] The benefits are: it allows the corn starch and coarse and fine residue mixture inside the packaging bag to slide smoothly, and all the dust generated during the feeding process is collected in the packaging bag, preventing dust from being generated; the screening stage of corn starch and coarse and fine residue eliminates the incomplete separation caused by the weight of the corn starch and coarse and fine residue mixture, and can achieve accurate multi-stage separation.

[0039] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
