Description

Technical Field

[0001] This utility model relates to the field of corn processing technology, and in particular to an automatic slag removal device. Background Technology

[0002] There are many methods for producing corn starch, but the two most commonly used processes are the wet process and the dry process. The wet process refers to the pre-processing method of corn raw materials in the starch industry, which involves soaking corn in warm water, grinding it coarsely and finely, and separating the germ, fiber, and protein to obtain a high-purity starch product.

[0003] Before soaking, the corn needs to be purified. Often, a vibrating screen with dust suction (wind power) is used to remove impurities of all sizes, and an electromagnetic separator is used to remove iron pieces before soaking the corn. This corn sorting process is cumbersome and the equipment investment cost is relatively high. Utility Model Content

[0004] In view of this, the present invention provides an automatic slag removal device, the main purpose of which is to reduce equipment investment costs and improve corn sorting efficiency.

[0005] To achieve the above objectives, this utility model mainly provides the following technical solutions:

[0006] This utility model provides an automatic slag removal device, which includes: a housing, a feeding pipe, and a slag capture unit;

[0007] The front wall of the box is connected to the water inlet pipe. Multiple partitions are arranged horizontally inside the box to divide the internal space of the box into multiple settling spaces. The rear wall of the box is connected to the conveying mechanism to convey the sorted materials.

[0008] The feeding pipe is located above the front side wall of the box and is used to feed the material to be sorted into the box.

[0009] The scum capture unit includes a chute and a transmission belt mechanism. One end of the chute is located on the liquid surface of the rear side wall of the tank, and the other end is inclined upward. The transmission belt mechanism is located above the chute, and the working surface of the transmission belt mechanism extends in the same direction as the chute. Multiple scrapers are arranged sequentially on the working surface of the transmission belt mechanism. The scraper located below the working surface of the transmission belt mechanism contacts the bottom wall of the chute and is used to drive the scum in the material to be sorted to move to the other end of the chute.

[0010] The purpose of this utility model and the technical problems to be solved can be further achieved by the following technical measures.

[0011] Optionally, the scraper has multiple through holes evenly distributed on its surface.

[0012] Optionally, the bottom wall of the box is inclined, the front side wall of the box is located at the upper end of the inclined direction of the bottom wall of the box, the rear side wall of the box is located at the lower end of the inclined direction of the bottom wall of the box, and the plurality of partitions are arranged sequentially along the inclined direction of the bottom wall of the box.

[0013] Optionally, the lower end of the bottom wall of the box in the inclined direction is connected to a drain pipe, and the drain pipe is equipped with a drain valve.

[0014] Optionally, it also includes a feeding hopper, which is connected to the upper end of the feeding pipe, and the lower end of the feeding pipe faces the upper port of the housing.

[0015] Optionally, a scum collection frame is also included, which is located below the other end of the chute.

[0016] Optionally, it may also include a blowpipe, which corresponds to the working surface of the transmission belt mechanism at the other end of the chute.

[0017] By employing the above technical solution, this utility model has at least the following advantages:

[0018] When using this device, the corn material to be sorted is fed into the box through the feeding pipe from the front side wall of the box. The corn material gradually spreads along the liquid surface inside the box, while the flushing water enters the box through the inlet pipe. The flushing water carries the corn material towards the rear side wall of the box. During the above process, heavy residues of different densities also flow with the water. The heavier residues with higher density settle faster in the water inside the box and move forward a short distance with the flushing water before entering the settling space. The lighter residues settle slower in the water inside the box and move forward a longer distance with the flushing water before entering the settling space. The density of the corn kernels is less than that of the heavy residues. The corn kernels move with the flushing water to the rear side wall of the box and then settle completely. The conveying mechanism transports the sorted corn kernels to the soaking tank to complete the subsequent soaking of the corn kernels.

[0019] The corn material fed into the tank also contains scum. The scum moves along the liquid surface of the tank with the flushing water to the rear side wall and concentrates at one end of the chute. The transmission belt mechanism drives multiple scrapers to move back and forth, so that the scrapers below the working surface of the transmission belt mechanism move upward along the inclined direction of the chute, thereby driving the scum upward along the inclined direction of the chute, so that the scum is thrown out from the other end of the chute. At the same time, because the scum moves upward along the chute, it prevents the water at one end of the chute from moving to the other end.

[0020] This device utilizes the different densities of the components in corn material to achieve the purpose of corn material sorting. It eliminates the need for electromagnetic separators and vibrating screens to remove impurities, reducing equipment investment, shortening the corn sorting process, and improving corn sorting efficiency.

[0023] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the specific implementation methods, structures, features, and effects according to this utility model application are described in detail below with reference to the accompanying drawings and preferred embodiments. In the following description, different "embodiments" or "embodiments" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0025] like Figure 1 As shown, an embodiment of the present invention provides an automatic slag removal device, which includes: a housing 1, a feeding pipe 2, and a slag capture section;

[0026] The front wall of the box 1 is connected to the water inlet pipe 3. Multiple partitions 4 are arranged horizontally inside the box 1 to divide the internal space of the box 1 into multiple settling spaces. The rear wall of the box 1 is connected to the conveying mechanism to convey the sorted materials.

[0027] The feeding pipe 2 is located above the front side wall of the box 1 and is used to feed the material to be sorted into the box 1.

[0028] The scum capture unit includes a chute 5 and a transmission belt mechanism 6. One end of the chute 5 is located on the liquid surface of the rear side wall of the tank 1, and the other end is inclined upward. The transmission belt mechanism 6 is located above the chute 5. The working surface of the transmission belt mechanism 6 extends in the same direction as the chute 5. Multiple scrapers 7 are arranged sequentially on the working surface of the transmission belt mechanism 6. The scrapers 7 located below the working surface of the transmission belt mechanism 6 contact the bottom wall of the chute 5 and are used to drive the scum in the material to be sorted to move to the other end of the chute 5.

[0029] The working process of the automatic slag removal device is as follows:

[0030] When using this device, the corn material to be sorted is fed into the box 1 from the front side wall through the feeding pipe 2. The corn material to be sorted gradually spreads along the liquid surface inside the box 1. At the same time, the rinsing water enters the box 1 through the water inlet pipe 3. The rinsing water carries the corn material to the rear side wall of the box 1. During the above process, heavy residues of different densities also flow with the water flow. The heavier residues with higher density settle faster in the water of the box 1 and move forward a short distance with the rinsing water before entering the settling space. The lighter residues settle slower in the water of the box 1 and move forward a longer distance with the rinsing water before entering the settling space. The density of the corn kernels is less than that of the heavy residues. The corn kernels move with the rinsing water to the rear side wall of the box 1 and then settle completely. The conveying mechanism transports the sorted corn kernels to the soaking tank 9 to complete the subsequent soaking of the corn kernels.

[0031] The corn material fed into the tank 1 also contains scum. The scum moves along the liquid surface of the tank 1 with the flushing water to the rear side wall and concentrates at one end of the chute 5. The transmission belt mechanism 6 drives multiple scrapers 7 to move back and forth, so that the scrapers 7 below the working surface of the transmission belt mechanism 6 move along the inclined direction of the chute 5, thereby driving the scum to move upward along the inclined direction of the chute 5, so that the scum is thrown out from the other end of the chute 5. At the same time, because the scum moves upward along the chute 5, the water at one end of the chute 5 is prevented from moving to the other end.

[0032] This device utilizes the different densities of the components in corn material to achieve the purpose of corn material sorting. It eliminates the need for electromagnetic separators and vibrating screens to remove impurities, reducing equipment investment, shortening the corn sorting process, and improving corn sorting efficiency.

[0033] Specifically, the conveying mechanism uses a conveying pump 8. The lower end of the rear wall of the box 1 is connected to the inlet pipe of the conveying pump 8, and the outlet pipe of the conveying pump 8 is connected to one side of the upper end of the soaking tank 9. The other side of the upper end of the soaking tank 9 is connected to one end of the overflow pipe, and the other end of the overflow pipe is connected to the water inlet pipe 3. The soaking tank 9 has a volume of 400 cubic meters, and the liquid level in the soaking tank 9 is higher than the liquid level in the box 1. The sorted corn kernels enter the soaking tank 9 with the water flow and settle to the bottom of the soaking tank 9. Excess water flows out of the soaking tank 9 through the overflow pipe and flows back to the box 1. By controlling the output power of the conveying pump 8, the speed at which the water overflows from the soaking tank 9 through the overflow pipe can be controlled, which in turn controls the speed of the water flow in the box 1. This adjusts the distance that each component in the corn material moves horizontally with the water flow, so that components of different densities settle sequentially into different settling spaces in the box 1, thereby achieving the purpose of corn sorting.

[0034] Specifically, the length of the transmission belt mechanism 6 is slightly greater than the length of the chute 5, and the scraper 7 located at the lower end of the working surface of the transmission belt mechanism 6 is slightly lower than one end of the chute 5, so that the transmission belt mechanism 6 drives the scraper 7 to sweep across the liquid surface of the tank 1 and move the scum towards one end of the chute 5.

[0035] Specifically, the lower side of the partition 4 is fixedly connected to the bottom wall of the tank 1, and the left and right sides of the partition 4 are fixedly connected to the opposite side walls of the tank 1. The surface of the partition 4 is evenly distributed with multiple filter holes. The flushing water flowing from front to back in the tank 1 enters one of the settling spaces and can also pass through the filter holes on the surface of the partition 4, thus avoiding excessive consumption of the kinetic energy of the flushing water by the partition 4. The pore size of the filter holes is smaller than the particle size of the heavy slag, thus preventing the heavy slag particles in the previous settling space from continuing to flow with the water flow to the next settling space, thereby achieving the step-by-step settling of the heavy slag.

[0036] Specifically, the working surface of the transmission belt mechanism 6 and multiple scrapers 7 are integrally formed and made of rubber.

[0037] In a specific embodiment, the scraper 7 has multiple through holes evenly distributed on its surface.

[0038] In this embodiment, specifically, the scraper 7 has multiple through holes evenly distributed on its surface. When the scraper 7 drives the scum to move upward along the chute 5, the water remaining in the chute 5 can flow back to the tank 1 through the multiple through holes on the scraper 7, ensuring the efficient utilization of water in the tank 1.

[0039] In a specific embodiment, the bottom wall of the box 1 is inclined, the front side wall of the box 1 is located at the upper end of the inclined direction of the bottom wall of the box 1, the rear side wall of the box 1 is located at the lower end of the inclined direction of the bottom wall of the box 1, and multiple partitions 4 are arranged sequentially along the inclined direction of the bottom wall of the box 1.

[0040] In this embodiment, specifically, the flushing water enters the tank 1 through the water inlet pipe 3 and flows along the inclined direction of the bottom wall of the tank 1. The potential energy of the flushing water is converted into kinetic energy, which helps to accelerate the generation of a speed difference between corn kernels and heavy residue, thereby facilitating the separation and sedimentation of corn kernels and heavy residue.

[0041] In a specific embodiment, the lower end of the bottom wall of the box 1 in the inclined direction is connected to the drain pipe 10, and the drain pipe 10 is equipped with a drain valve 11.

[0042] In this embodiment, specifically, when there are many impurities in the box 1 and it needs to be cleaned, the drain valve 11 can be opened to drain the water in the box 1.

[0043] In a specific embodiment, it also includes a feeding hopper 12, which is connected to the upper end of the feeding pipe 2, and the lower end of the feeding pipe 2 faces the upper port of the box body 1.

[0044] In this embodiment, specifically, the operator can put the corn material to be sorted into the feeding hopper 12 to increase the area of ​​the feeding pipe 2 for receiving materials.

[0045] In a specific embodiment, a scum collection frame 13 is also included, which is located below the other end of the chute 5.

[0046] In this embodiment, specifically, the scum collection frame 13 is located below the other end of the chute 5 and is used to receive the scum thrown out from the other end of the chute 5.

[0047] In a specific embodiment, a blow pipe 14 is also included, which corresponds to the working surface of the transmission belt mechanism 6 at the other end of the chute 5.

[0048] In this embodiment, specifically, the air blown out by the blowpipe 14 removes the scum adhering to the surface of the working surface scraper 7 of the transmission belt mechanism 6 at the other end of the chute 5, preventing the scum from re-entering the water in the tank 1 along with the scraper 7.

[0049] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
