Description

Technical Field

[0001] This application relates to the field of potato processing equipment technology, and more specifically, to a potato impurity removal and pulping device. Background Technology

[0002] Potato pulping refers to washing potatoes and then crushing them into a pulp using a grinder or similar device. The resulting pulp is primarily used to produce starch or other foods, such as purified potato starch.

[0003] In related technologies, because the surface of potato raw materials often contains some mud and sand, and the tuber roots also contain coarse fiber impurities, the resulting pulp after potato pulping and crushing will contain some impurities. Therefore, the potato pulp needs to be filtered to obtain a purer pulp.

[0004] However, the traditional method requires manual processing, repeatedly filtering potato pulp through sieves to remove impurities. This method has the following drawbacks: manual operation is labor-intensive and has limited processing efficiency; the sieves are prone to clogging, and need to be cleaned after each batch of potato pulp is processed. While existing mechanical filtration equipment can improve overall efficiency, it generally suffers from problems such as easy clogging of the sieves, high levels of impurity residue, and complex structure making maintenance difficult. Utility Model Content

[0005] In view of this, the present application provides a potato impurity removal and pulping device, which utilizes the synergistic effect of the fan-shaped spreading plate and the brush in the rotating impurity removal mechanism to achieve the function of directional movement of impurities towards the edge of the circular screen plate.

The shaft has a brush and a fan-shaped paving plate arranged radially symmetrically on its side wall. Its bottom is connected to the output shaft flange of a servo motor, which is fixedly mounted inside the protective cover.

[0013] In some possible implementations, the top of the vertical pivot is provided with a height-adjustable conical tip.

[0014] In some possible implementations, the brush includes a substrate and bristles, the substrate being connected to the sidewall of the vertical rotating shaft by bolts, the bristles being located on the bottom surface of the substrate and abutting against the upper surface of the circular screen plate, and the upper surface of the substrate being provided with guide slopes that slope downwards to both sides in its width direction.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0037] like Figure 1 and Figure 4 As shown in the figure, the potato impurity removal and pulping device provided in this application embodiment includes a frame 100, a crushing chamber 200, a receiving plate 400, a circular screen plate 500, and a rotary impurity removal mechanism. The frame 100 is the supporting structure of the entire impurity removal and pulping device. The frame 100 is formed into a frame structure by welding 304 stainless steel, and its bottom is provided with a rubber anti-slip pad. A motor bracket is fixedly installed on the side wall of the frame 100, and a drive motor 110 is mounted on the motor frame 100 through a flange.

[0038] A horizontal crushing chamber 200 is horizontally arranged above the frame 100. The crushing chamber 200 has a horizontal cylindrical structure, and its inner wall is lined with a removable wear-resistant ceramic plate. A crushing shaft 300 is horizontally inserted and rotatably installed inside the crushing chamber 200. Several crushing blades 310 are also fixedly installed on the outer wall of the crushing shaft 300. Specifically, 6 to 8 sets of crushing blades 310 are evenly distributed along the circumference of the surface of the crushing shaft 300. The included angle between adjacent crushing blades 310 is between 45° and 60°. Each set of crushing blades 310 is made of cemented carbide.

[0039] The drive shaft of the drive motor 110 is connected to the crushing shaft 300 via a belt 320, so the crushing shaft 300 can rotate under the drive of the drive motor 110 and crush the potatoes through the crushing blades 310. In addition, the bottom of the crushing chamber 200 is provided with a tapered discharge pipe 210, the cone angle of which is between 60° and 90°, so that the slurry formed after the potatoes are crushed can flow out through the discharge pipe 210 under the action of gravity.

[0040] The receiving plate 400 is a plate-shaped structure mounted on the frame 100. Located below the discharge pipe 210, the receiving plate 400 has a circular mounting hole 410 in its center along its thickness direction. The circular mounting hole 410 and the discharge pipe 210 are coaxial, meaning their centers are on the same vertical line. A circular screen plate 500 is mounted on the receiving plate 400 through this circular mounting hole 410. The outer diameters of both the circular screen plate 500 and the circular mounting hole 410 are larger than the outer diameter of the discharge pipe 210.

[0041] The circular sieve plate 500 has multiple sieve holes along its thickness direction. The circular sieve plate 500 can be made of 304 stainless steel with a thickness between 3mm and 5mm. Therefore, the potato pulp flowing out through the pulp outlet pipe 210 falls onto the circular sieve plate 500 for screening. Preferably, the circular sieve plate 500 is detachably connected within the circular mounting hole 410, facilitating subsequent replacement of the circular sieve plate 500 according to actual needs.

[0042] In this embodiment, the rotary impurity removal mechanism includes a vertical rotating shaft 600, which is rotatably disposed at the center of the circular sieve plate 500. The side wall of the vertical rotating shaft 600 is radially symmetrically provided with a brush 800 and a fan-shaped paving plate 700. The bottom of the vertical rotating shaft 600 is coaxially and fixedly connected to the output shaft of the servo motor 900 through a coupling.

[0043] The fan-shaped paving plate 700 is a fan-shaped plate structure made of 2mm thick 316L stainless steel plate, and its bottom surface is provided with wear-resistant strips made of polytetrafluoroethylene. The bottom surface of the circular sieve plate 500 is also coaxially fixed with a hemispherical protective cover 510. The top of the protective cover 510 is provided with a cylinder 511, which is inserted into the center of the circular sieve plate 500 by interference fit. The vertical rotating shaft 600 is rotatably set inside the cylinder 511.

[0044] The servo motor 900 is a vertical drive motor, which is mounted on the ground via a base at the bottom. The servo motor 900 is located inside the protective cover 510, which covers the servo motor 900 to prevent potato pulp falling through the circular sieve plate 500 from covering the surface of the servo motor 900 and affecting its normal operation.

[0045] The following is combined Figures 1-4 The working principle and working process of the potato impurity removal and pulping device provided in the embodiments of this application are described.

[0046] After washing, the potatoes are placed into the crushing chamber 200. The drive motor 110 drives the crushing shaft 300 and the crushing blades 310 to rotate synchronously via the belt 320. The staggered crushing blades 310 perform multi-stage shearing on the potatoes. After the above treatment, the potatoes will form a viscous slurry. This slurry will accumulate at the bottom of the crushing chamber 200 and flow outward through the slurry outlet pipe 210 under the action of gravity, eventually falling into the central area of ​​the circular screen plate 500.

[0047] The servo motor 900 drives the vertical shaft 600 to rotate at a constant speed. The vertical shaft 600 drives the fan-shaped spreading plate 700 to quickly spread the slurry that falls from the slurry pipe 210 onto the surface of the circular screen plate 500 into a uniform thin layer of 1mm to 3mm thickness, so that some of the potato slurry can fall through the sieve holes of the circular screen plate 500 under the action of gravity. At the same time, the brush 800 rotates synchronously with the vertical shaft 600 and the fan-shaped spreading plate 700. The soft bristles of the brush 800 come into contact with the circular screen plate 500 and clean the impurities such as coarse fibers mixed in with the potato slurry, so as to prevent the impurities from clogging the sieve holes of the circular screen plate 500.

[0048] In practical use, a collection box or other container can be placed below the circular sieve plate 500 to facilitate the directional collection of the filtered potato pulp. If workers find a large amount of impurities on the sieve plate, they can manually clean it to ensure the smooth progress of the process. Alternatively, a guide channel can be installed at the edge of the circular sieve plate 500, allowing impurities to be collected directionally. This structural design allows for the simultaneous removal of impurities from potatoes during the crushing process to form a pulp, thus simplifying the traditional operating procedures.

[0049] In the potato impurity removal and pulping device provided in this application embodiment, the vertical rotating shaft 600 can drive the fan-shaped spreading plate 700 to evenly spread the pulp into a thin layer on the upper surface of the circular screen plate 500. Combined with the directional cleaning function of the synchronously rotating brush 800, impurities can move synchronously circumferentially with the brush, preventing them from accumulating on the circular screen plate 500 and clogging the screen holes. With the above structural design, by integrating a rotating impurity removal mechanism below the crushing chamber 200, continuous crushing and impurity removal operations are achieved. Furthermore, the crushing and impurity removal operations can be carried out continuously without interruption, and there is no need to stop the machine to clean the circular screen plate 500 during this process, thereby greatly improving the potato pulping efficiency.

[0050] In some embodiments, the top of the vertical shaft 600 is provided with a height-adjustable conical tip 610. Specifically, the top of the vertical shaft 600 is provided with a threaded rod, and the bottom of the conical tip 610 is provided with an adjusting thread adapted to the threaded rod. The two can be adjusted up and down through the thread, and the cone angle of the conical tip 610 is between 60° and 90°.

[0051] By incorporating a height-adjustable conical tip 610, the dispersion angle of the potato slurry can be dynamically adjusted according to the feeding speed. The special cone angle design not only creates a guiding slope for the potato slurry but also prevents it from accumulating at the top of the vertical rotating shaft 600, ensuring that the potato slurry spreads evenly radially. Furthermore, the threaded adjustment structure facilitates the adjustment of the conical tip 610 to accommodate the processing needs of potato slurries with different viscosities.

[0052] In some embodiments, the brush 800 includes a substrate 810 and bristles 820. The substrate 810 may be made of polyurethane material and can be connected to the side wall of the vertical rotating shaft 600 via four sets of M6 countersunk bolts (not shown in the figure). The bristles 820 are made of nylon material and are fixedly mounted on the bottom plate of the substrate 810, abutting against the upper surface of the circular screen plate 500. The upper surface of the substrate 810 is provided with guide slopes 811 that slope downwards to both sides in its width direction.

[0053] The modular design of the base plate 810, with its split bolt connection, allows for individual replacement of worn brush 800 components. The guide slope 811 formed at the top of the base plate 810 creates a drainage gradient, directing impurities during cleaning to the outside of the brush 800's movement path. The nylon bristles 820 make elastic contact with the upper surface of the circular screen plate 500, ensuring effective cleaning while preventing damage to the screen plate 500.

[0054] In some embodiments, the circular area formed by the fan-shaped paving plate 700 and the brush is adapted to the upper surface area of ​​the circular screen plate 500. Specifically, the radial length of the fan-shaped paving plate 700 is 0.8-0.9 times the radius of the circular screen plate 500, and the cleaning area formed by the fan-shaped paving plate 700 and the brush 800 covers more than 85% of the area of ​​the circular screen plate 500. This can greatly shorten the residence time of impurities on the upper surface of the circular screen plate 500 and significantly reduce the probability of screen clogging.
