Description

Technical Field

[0001] This utility model belongs to the field of food production technology, specifically a device to prevent splashing after starch is sieved. Background Technology

[0002] As living standards improve, people's demands for material and cultural products are also increasing, including higher standards for food. To develop safer, healthier, and more cost-effective foods, food manufacturers often use starch in the food processing process to replace some colloidal substances and enrich the product's flavor. Before use, starch needs to be sieved (using a vibrating screen to filter the starch) to prevent foreign matter from entering the starch and ensure food safety.

[0003] For households, starch sieving is mainly done through manual flour sieves and electric handheld sieves, which are simple to operate. However, for food processing plants that process in batches, vibrating screens, rotary vibrating screens, or air classifiers are used, with vibrating screens being the most common. These screens allow starch granules to move actively, thus separating out foreign objects.

[0004] During the starch sieving process, dust splashing and pollution are problems that exist. In addition, the splashed starch not only causes economic losses, but also harms the health of employees, pollutes the environment, and poses a risk of dust explosion. Utility Model Content

[0005] To address the problem that dust splashing and pollution caused by vibration after starch sieving, which not only results in economic losses but also harms the health of employees, this utility model provides a starch sieving anti-splashing device.

[0006] This utility model is achieved through the following technical solution: A starch sieving anti-splashing device includes a fixed frame, a first support plate fixedly installed on the upper side of the fixed frame, a first spring connected to the lower side of the first support plate, a sieve bucket connected to the lower side of the first spring, a vibrator connected to the side of the sieve bucket, a cylinder connected to the lower side of the sieve bucket by bolts, an inverted frustum-shaped silicone buffer pad connected to the bottom of the cylinder, a second spring connected to the lower side of the cylinder, a second support plate fixedly connected to the fixed frame connected to the lower side of the second spring, a storage tank connected to the lower side of the second support plate, a first flexible connection connected between the storage tank and the cylinder, and a switching mechanism connected to the bottom of the storage tank.

[0007] A further improvement of this utility model is that a second flexible connection is installed between the first support plate and the screen hopper, and a hopper is installed on the upper side of the first support plate.

[0008] A further improvement of this utility model is that the side of the sieve hopper is provided with an opening, and an openable baffle is rotatably connected and installed on the outside of the opening.

[0009] A further improvement of this utility model is that a viewing window is provided on the side of the storage tank.

[0010] A further improvement of this utility model is that a straight rod is provided on the side of the storage tank, and a removable rubber hammer is connected to the straight rod.

[0011] A further improvement of this utility model is that the switching mechanism includes a guide rail frame connected and installed on the lower side of the storage tank, a slide plate slidably embedded in the guide rail frame, a threaded hole on the slide plate, a servo motor connected and installed on the fixing frame, and a lead screw threadedly connected to the threaded hole at the output end of the servo motor.

[0012] A further improvement of this utility model is that an exhaust device is provided on the side of the storage tank. The exhaust device includes a pressure sensing valve connected and installed on the outer wall of the storage tank. The pressure sensing valve is connected to a coarse filter through a pipe.

[0013] A further improvement of this invention is that a quick connector is provided between the pipe and the coarse filter.

[0014] As can be seen from the above technical solutions, the beneficial effects of this utility model are: Workers place starch in a stainless steel sieve hopper and turn on the vibrator. Under the action of the vibrating sieve, the starch slowly passes through the hopper and falls onto a silicone buffer pad, reducing splashing and rebound. Due to the vibration, the starch on the silicone buffer pad flows down a slope through a central hole into a storage tank. When the storage tank is almost full, an infrared sensor inside the tank sounds an alarm, and workers promptly remove the sieved starch through the bottom outlet. This device uses a closed storage tank to ensure that all starch passing through the sieve falls completely into the tank. The silicone buffer pad allows the starch to fall from a low height when it is almost completely sieved, reducing dust spillage from the sieve. Furthermore, the small opening at the bottom of the silicone buffer pad after the starch falls into the storage tank reduces the amount of starch dust spilling out, preventing waste and reducing the risk of dust injury to employees and dust explosions.

[0021] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0022] like Figure 1-4As shown, a starch sieving anti-splashing device includes a stainless steel frame 1. A first support plate 2 is fixedly installed on the upper side of the frame 1. A first spring 3 is connected and installed on the lower side of the first support plate 2. A sieve hopper 4 is connected and installed on the lower side of the first spring 3. The screen on the sieve hopper 4 can be replaced with different mesh sizes to meet different requirements. At the same time, several reinforcing ribs can be set at the bottom of the sieve hopper 4 to prevent starch from damaging the screen. An eccentric wheel vibrator 5 is connected and installed on the side of the sieve hopper 4. A cylinder 7 is detachably connected and installed on the lower side of the sieve hopper 4 by bolts 6, and a gasket is provided at the connection surface for sealing. A frustum-shaped silicone buffer pad 8 is connected and installed at the bottom of the cylinder 7. The silicone buffer pad 8 is open on both the top and bottom sides. A second spring 9 is connected and installed below the cylinder 7. All springs are springs with high stiffness. A second support plate 10 is connected and installed below the second spring 9 and is fixedly connected to the fixed frame 1. A storage tank 11 is connected and installed below the second support plate 10. A first flexible connection 12 made of food-grade canvas, silicone and polyurethane is connected and installed between the storage tank 11 and the cylinder 7. A switch mechanism 13 that can open and close the material outlet is connected and installed at the bottom of the storage tank 11.

[0023] Workers place starch in a stainless steel sieve hopper 4 and turn on the vibrator 5. Under the action of the sieve hopper 4, the starch slowly passes through the screen and falls onto the silicone buffer pad 8, reducing starch splashing and rebound. Due to the vibration of the vibrator 5, the starch falling onto the silicone buffer pad 8 will flow down the slope through the central hole into the storage tank 11. When the storage tank 11 is about to be full of starch, the radar level gauge inside the tank will sound an alarm. Workers will then promptly remove the sieved starch using the discharge port switch mechanism 13 at the bottom of the storage tank. This device uses a closed storage tank 11 to ensure that the starch sieved by the sieve 4 falls completely into the storage tank 11, thus guaranteeing the starch sieving speed. The silicone buffer pad 8 allows the starch in the sieve hopper to fall onto the silicone buffer pad at a lower height when the starch is almost completely sieved, reducing the amount of dust emitted from the sieve. At the same time, after the starch falls into the storage tank, the bottom opening of the silicone buffer pad is small, reducing the amount of starch dust that overflows from the opening in the storage tank, avoiding starch dust splashing and waste, and also reducing the harm of dust to employees and reducing the risk of dust explosion.

[0024] A second flexible connection 15 is installed between the first support plate 2 and the screen hopper 4, and a hopper 16 is installed on the upper side of the first support plate 2. The hopper 16 can increase the starch holding capacity of the screen hopper 4, prevent starch from overflowing from the screen hopper 4, and reduce starch dust. At the same time, since the screen hopper 4 and the hopper 16 are connected by a flexible connection, the vibration load on the vibrator 5 caused by a large amount of starch can be reduced, thereby improving the screening efficiency of the screen hopper 4.

[0025] The sieve hopper 4 has an opening on its side, and an openable baffle 41 is rotatably connected to the outside of the opening. This allows for convenient and periodic cleaning of large starch particles left in the sieve hopper 4 after sieving, ensuring the sieving efficiency of the sieve hopper 4.

[0026] The storage tank 11 has a tempered glass viewing window 17 on its side. The viewing window 17 allows the operator to observe the starch content inside, enabling them to monitor the internal conditions and perform cleaning.

[0027] The storage tank 11 has a straight rod 18 on its side, and a removable rubber hammer 19 is connected to the straight rod 18. When workers release the starch from the storage tank 11, some starch may stick to the inner wall of the storage tank 11. The rubber hammer 19 hanging on the straight rod 18 is removed and the side wall of the storage tank 11 is tapped to shake off the residual starch, preventing the starch from deteriorating and affecting food safety.

[0028] The switching mechanism 13 includes a guide rail frame 131 connected and installed on the lower side of the storage tank 11. A slide plate 132 is slidably embedded in the guide rail frame 131. The slide plate 132 has a threaded hole 133. A servo motor 134 is connected and installed on the fixing frame 1. The output end of the servo motor 134 is connected and installed with a lead screw 135 that is threadedly connected to the threaded hole 133. When the servo motor 134 is started, it drives the lead screw 135 to rotate. The lead screw 135 engages with the threaded hole 133, causing the slide plate 132 to slide horizontally along the guide rail frame 131. This allows the discharge port to be opened and closed electrically, reducing the inconvenience of manual adjustment.

[0029] The storage tank 11 is equipped with an exhaust device 14 on its side. The exhaust device 14 includes a pressure sensing valve 141 connected to and installed on the outer wall of the storage tank 11. The pressure sensing valve 141 is mechanical and is connected to a coarse filter 143 via a pipe 142. As more and more starch enters, positive pressure is generated inside the storage tank 11. This pressure resists the movement of the screen, making the screen vibration difficult. Because the starch on the screen blocks the ventilation, the pressure inside the storage tank 11 increases and the starch flow rate slows down. When the pressure inside the storage tank 11 reaches a certain level, the pressure sensing valve 141 will exhaust gas in real time according to the pressure level to achieve the purpose of stabilizing the pressure inside the storage tank 11 and ensuring that the starch flows smoothly downward.

[0030] A quick-connector 144 is provided between the pipe 142 and the coarse filter 143. The quick-connector 144 is connected by snap-fit ​​bolts and has good tightness and sealing performance. The quick-connector 144 can easily disassemble the coarse filter 143 to clean or replace the clogged filter screen and ensure air exchange efficiency.

[0031] The hopper 16 is equipped with a stainless steel cover with a handle for easy opening. This further reduces dust pollution caused by starch splashing and prevents starch dust from overflowing when the starch is about to be screened, as there is no starch covering the hopper 4.

[0032] The staff places the starch on the sieve 4 and turns on the vibrator 5. Under the action of the stainless steel vibrating sieve 4, the starch slowly passes through the screen and enters the lower stainless steel storage tank 11. As more and more starch enters, the sealing effect of the starch on the sieve 4 causes the pressure inside to increase and the starch flow rate to slow down. When the pressure inside the storage tank 11 reaches a certain level, the pressure sensing valve 141 will release the gas to stabilize the pressure inside the stainless steel storage tank 11 and ensure that the starch flows smoothly downward. When the starch is about to fill the storage tank 11, the radar level gauge inside the tank will sound an alarm and then stop the vibrator 5 from vibrating and screening. The operator starts the servo motor 134 to drive the slide plate 132 to move, opens the lower discharge port, and takes out the screened starch in time. At the same time, the situation inside the storage tank 11 can be observed through the viewing window. When there is a lot of starch stuck to the inner wall of the storage tank 11, the rubber hammer 19 can be used to knock the starch stuck to the tank wall off. Meanwhile, the coarse filter 143 in the exhaust device 14 can effectively block the starch from flowing out. When the coarse filter 143 is severely clogged, the coarse filter 143 can be disassembled for cleaning or replacement by opening the quick connector 144. This device uses a closed storage tank to ensure that the starch sieved by the sieve falls completely into the storage tank, preventing starch dust from splashing and causing waste. It also reduces the harm of dust to employees and lowers the risk of dust explosion.
