Description

Technical Field

[0001] This utility model relates to the field of scraper technology, and more specifically, to a scraper for scraping the bottom of a sugar dissolving tank. Background Technology

[0002] Saccharification refers to the process by which starch is broken down into sweet products by adding water. It is a major process in the manufacture of starch-based sugars and also a major process in the fermentation of many intermediate products in food or pharmaceuticals.

[0003] The stirring paddle and wall scraper of the sugar dissolving tank are important components of the sugar dissolving tank stirring device, mainly used to solve the problem of material sticking to the wall during the pharmaceutical sugar dissolving process; The scraper blade rotates along with the agitator, and under the action of centrifugal force, it always conforms to and adheres closely to the tank wall. By continuously scraping the tank wall, new material interfaces are constantly created on the tank wall, effectively preventing high-concentration, viscous pharmaceutical materials from sticking to the wall, scorching, and discoloring during the heating and sugar-refining process, thus ensuring the smooth progress of the sugar-refining process. However, currently, the angle of the agitator blade scraper blade inside the sugar-refining tank is fixed, which causes the scraper blade to be continuously in contact with the inner wall of the tank during the rotation of the agitator. Long-term use results in significant wear on the scraper blade. Therefore, a scraper blade for the bottom agitator blade of the sugar-refining tank is provided. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a stirring paddle and wall scraper at the bottom of the sugar dissolving tank, which aims to solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a bottom stirring paddle scraper for scraping the wall of a sugar dissolving tank, including a stirring frame, wherein the bottom of the stirring frame is equipped with an integrated wall scraping adjustment component; The integrated wall scraping adjustment assembly includes a pressure plate fixedly installed at the bottom of the stirring rack, an elastic V-plate movably sleeved on the outside of the pressure plate, and a scraper strip detachably connected to the outside of the elastic V-plate. A threaded cylinder is fixedly installed at the top center of the pressure plate. A lead screw is threaded through the inner hole of the threaded cylinder. The bottom end of the lead screw is rotatably connected to a limiting plate through a rotating connector. The limiting plate has abutment grooves adapted to the elastic V plate on both sides. The abutment grooves are sleeved on the outside of the elastic V plate and slide with the elastic V plate.

[0006] Optionally, in a possible implementation, the inner walls of the elastic V-plate are integrally formed with slide rails on both sides, and the two ends of the pressure plate are respectively provided with slide grooves along their length. The slide rails are embedded in the slide grooves and form a sliding guide fit structure with the slide grooves. The elastic V-plate is made of food-grade elastic metal material. The V-shaped opening of the elastic V-plate is set towards the inner wall of the sugar dissolving tank, and the curvature of the elastic V-plate matches the curvature of the inner wall of the sugar dissolving tank. The scraper is made of food-grade silicone material. A clamping plate is provided on the side of the scraper away from the elastic V-plate. The clamping plate is connected to the elastic V-plate by fastening bolts passing through the clamping plate and the scraper in sequence, so as to realize the detachable fixation of the scraper on the outside of the elastic V-plate. Optionally, in a possible implementation, a plurality of stirring rods are uniformly fixedly connected to the side of the elastic V-plate along its length direction. The plurality of stirring rods are arranged in parallel and spaced apart, and the axial direction of the stirring rods is perpendicular to the length direction of the elastic V-plate. The top end of the lead screw extends to the top of the stirring frame. The contact groove elastically abuts against the outer wall of the elastic V-plate. The rotating connector is a deep groove ball bearing. The inner ring of the deep groove ball bearing is interference-fitted with the bottom end of the lead screw. The outer ring of the deep groove ball bearing is fixedly connected to the top end of the limiting plate. The technical effects and advantages of this utility model are as follows: The elastic V-plate, made of food-grade elastic material, possesses excellent deformation and recovery capabilities. Its elasticity adapts to the curvature of the tank wall, avoiding rigid friction. Combined with an adjustment structure consisting of a threaded cylinder, screw, and limiting plate, the screw can be rotated to control the up-and-down movement of the limiting plate, thus adjusting the degree of deformation of the elastic V-plate. To reduce wear, the limiting plate can be pressed down to slightly move the ends of the elastic V-plate away from the tank wall, reducing the contact pressure between the scraper and the tank wall. To enhance the scraping effect, the limiting plate can be loosened, allowing the elastic V-plate to naturally unfold and conform to the tank wall. This adjustable fit design completely avoids continuous rigid contact between the scraper and the tank wall, significantly reducing the wear rate of the scraper, extending the service life of the scraper and the elastic V-plate, and reducing maintenance frequency and costs. The flexible V-plate has a V-shaped opening facing the tank wall. Combined with centrifugal force, it naturally expands towards the tank wall during rotation, ensuring that the scraper always fits tightly against the tank wall without any dead corners. The scraper is made of food-grade silicone, which is soft and has good sealing properties. It can thoroughly scrape off the material adhering to the tank wall, constantly creating new material interfaces and preventing the material from scorching and discoloring due to prolonged contact with the tank wall. When the stirring rod rotates with the overall structure, it can break the laminar flow state of the material inside the tank, forming a dual stirring effect in both the longitudinal and transverse directions, promoting material convection. It can cover different areas inside the tank, especially the material at the bottom of the sugar dissolving tank, effectively stirring it to ensure that the material is heated evenly, accelerating the dissolving rate, improving sugar dissolving efficiency and the uniformity of material dissolution.

[0013] 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.

[0014] This embodiment discloses a scraper for scraping the bottom of the sugar dissolving tank, which aims to solve the problem in the prior art where the angle of the scraper of the stirring paddle in the sugar dissolving tank is fixed, resulting in the scraper continuously adhering to the inner wall of the tank during the rotation of the stirring paddle and causing large wear over long-term use. At the same time, it further optimizes the stirring effect, improves the stability of the sugar dissolving process and the material handling efficiency, and the specific settings are as follows.

[0015] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the bottom stirring paddle scraper of the sugar dissolving tank includes a stirring frame 1. The stirring frame 1 serves as the support and power transmission core of the entire scraper structure. Its top can be fixedly connected to the stirring drive device of the sugar dissolving tank, such as the output shaft of a motor, and the drive device drives the entire structure to rotate around the central axis of the sugar dissolving tank.

[0016] An integrated component is installed at the bottom of the stirring rack 1. This integrated component is the key part for realizing the wall scraping function adjustment and efficient stirring, and specifically includes the following structure: Pressure plate 2 and elastic V-plate 3: Pressure plate 2 is V-shaped and horizontally installed at the bottom of stirring rack 1, with elastic V-plate 3 covering its outer side. Elastic V-plate 3 can be made of food-grade elastic stainless steel, possessing good deformation capacity and resilience. Its V-shaped opening faces the inner wall of the sugar dissolving tank, allowing it to adapt to the curvature of the tank wall through its own elasticity. Figure 3 As shown, slide rails 9 are integrally formed on both sides of the inner wall of the elastic V-plate 3. Correspondingly, grooves 10 are formed at both ends of the pressure plate 2 along the length direction. The slide rails 9 are embedded in the grooves 10 and slidably connected to the grooves 10. This structure of slide rails 9 and grooves 10 not only realizes the detachable connection between the elastic V-plate 3 and the pressure plate 2, but also allows the elastic V-plate 3 to slide slightly along the length direction of the pressure plate 2, that is, towards or away from the tank wall, providing a basis for adjusting the wall scraping gap.

[0017] Scraper 4 and clamp 12: such as Figure 3 As shown, a scraper 4 is fitted to the outer side of the elastic V-plate 3. The scraper 4 is made of food-grade silicone and can fit tightly against the inner wall of the sugar dissolving tank to prevent material from sticking to the wall. To ensure that the scraper 4 is firmly fixed and easy to replace, a clamping plate 12 is provided on the side of the scraper 4 away from the elastic V-plate 3. The clamping plate 12 is a metal plate that matches the curvature of the elastic V-plate 3. Stainless steel bolts pass through the clamping plate 12 and the scraper 4 in sequence and are then threadedly connected to the elastic V-plate 3 to achieve a tight fixation of the three. When the scraper 4 wears out due to long-term use, it can be replaced simply by removing the bolts, reducing maintenance costs.

[0018] Stirring rod 11: as Figure 3 As shown, several stirring rods 11 are uniformly welded to the side of the elastic V plate 3. The multiple stirring rods 11 are arranged side by side along the length of the elastic V plate 3. When the stirring frame 1 drives the overall structure to rotate, the stirring rods 11 can assist in stirring the material in the sugar dissolving tank, break the laminar flow state of the material, and promote the uniform heating and dissolution of the material. It is especially suitable for the sugar dissolving process of high-concentration viscous pharmaceutical materials.

[0019] like Figure 4As shown, a threaded cylinder 5 is vertically welded to the top center of the pressure plate 2. The inner hole of the threaded cylinder 5 has an internal thread, and a matching lead screw 6 passes through the middle. The top of the lead screw 6 extends to the top of the stirring frame 1 and is fixed with an adjustment knob (not shown in the figure). The bottom end is rotatably connected to a limit plate 7 via a bearing. On both sides of the limit plate 7, there are contact grooves 8 that are adapted to the elastic V plate 3. The inner wall of the contact groove 8 is covered with a wear-resistant rubber pad. The contact groove 8 covers the outer side of the elastic V plate 3 and is slidably connected to the elastic V plate 3. The specific working principle is as follows: Before installation or use, the adhesion between the scraper 4 and the tank wall can be adjusted according to the actual wear condition of the inner wall of the sugar dissolving tank and the viscosity of the material. During adjustment, the adjustment knob at the top of the lead screw 6 is rotated. Since the lead screw 6 is threadedly engaged with the threaded cylinder 5, the lead screw 6 will move up and down along the axis of the threaded cylinder 5, thereby driving the limiting plate 7 to move up and down synchronously. When the limiting plate 7 moves downward, the contact groove 8 applies downward pressure to the middle of the elastic V plate 3, causing the two ends of the elastic V plate 3 to deform away from the tank wall, increasing the gap between the scraper 4 and the tank wall. When the limiting plate 7 moves upward, the pressure of the contact groove 8 on the elastic V plate 3 decreases, and the elastic V plate 3 recovers its deformation under its own elasticity, with the two ends moving closer to the tank wall, reducing the gap between the scraper 4 and the tank wall. Through this adjustment method, the scraper 4 can avoid excessive pressure on the tank wall for a long time, significantly reducing the wear rate of the scraper 4 and extending its service life.

[0020] The stirring drive of the sugar dissolving tank is activated, causing the stirring frame 1 to rotate, which in turn drives the integrated assembly to rotate synchronously. Under centrifugal force, the elastic V-plate 3 extends further towards the tank wall, allowing the scraper 4 to fit tightly against the tank wall. As it rotates, it continuously scrapes the tank wall, disrupting the adhesion conditions of the material and preventing high-concentration, viscous medicinal materials from sticking to the wall, scorching, or discoloring during the sugar dissolving process. Simultaneously, the stirring rod 11 on the side of the elastic V-plate 3 rotates with the overall structure, stirring the material inside the tank, promoting material convection and heat transfer, ensuring uniform dissolution of the material, and improving sugar dissolving efficiency and quality.

[0021] The slide rail 9 and slide groove 10 structure between the elastic V-plate 3 and the pressure plate 2 can limit the lateral displacement of the elastic V-plate 3 during deformation or adjustment, ensuring that the elastic V-plate 3 always moves in the preset direction and avoiding unstable adhesion between the scraper 4 and the tank wall due to shaking. In addition, the sliding connection between the limiting plate 7 and the elastic V-plate 3 not only limits the elastic V-plate 3, but also does not hinder the normal deformation of the elastic V-plate 3 during rotation, ensuring the stability of the overall structure operation.

[0022] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
