Description

Technical Field

[0001] This utility model relates to the field of food processing technology, specifically to a dust removal and separation device for food processing. Background Technology

[0002] Food processing, as a key link connecting agricultural production and the consumer market, directly uses agricultural, forestry, animal husbandry, and fishery products as raw materials, covering grain milling, feed processing, vegetable oil and sugar processing, slaughtering and meat processing, aquatic product processing, as well as the processing of vegetables, fruits, and nuts. In recent years, with the improvement of residents' living standards and changes in consumption concepts, consumers have put forward higher requirements for the safety, hygiene, and quality stability of food.

[0003] The cleanliness of raw materials used in food processing is a fundamental condition for ensuring food safety. Dust and impurities in raw materials not only affect the taste and appearance of food, but may also carry harmful substances such as microorganisms and heavy metals, posing a potential threat to consumers' health.

[0004] Among the raw materials required for food processing, corn is a widely used ingredient. Its rich nutritional components, diverse physical properties, and processing adaptability make it occupy an important position in the food industry. However, during the planting, harvesting, transportation, and storage of corn, a large amount of dust, mud, straw fragments, and other impurities inevitably adhere to it.

[0005] Based on this, the present invention designs a dust removal and separation device for food processing to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a dust removal and separation device for food processing.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A dust removal and separation device for food processing includes multiple connecting rods. A dust removal mechanism is fixedly connected to the upper ends of the multiple connecting rods. Two support rods are fixedly connected to the lower part of the dust removal mechanism. A separation mechanism is fixedly connected to the lower ends of the two support rods and the multiple connecting rods. The dust removal mechanism includes a connecting plate. The lower end of the connecting plate is fixedly connected to the upper ends of the two support rods. A pad is fixedly connected to the upper end of the connecting plate. A dust removal component is fixedly connected to the upper end of the pad. A controller is fixedly installed on one side of the dust removal component. A rinsing component is fixedly connected to the lower end of the connecting plate. Furthermore, the dust removal assembly includes a feeding hopper, an output pipe fixedly connected to the front end of the feeding hopper, multiple buffer plates fixedly connected to the inner cavity of the feeding hopper, a fan fixedly connected to the rear end of the feeding hopper, the lower end of the fan fixedly connected to the upper end of the pad block, and a guide plate fixedly connected to the inner cavity of the feeding hopper. The raw material enters from the feeding hopper, and its descent speed is reduced by the buffer plates. The fan generates airflow, and when the raw material passes through the fan, most of the impurities mixed in it are blown away from the output pipe, thus performing the initial dust removal. Furthermore, the rinsing assembly includes a water pump, the output end of which is fixedly connected to a water injection pipe. A diversion pipe is fixedly connected and connected to the outer surface of the water injection pipe. Multiple rinsing pipes are fixedly connected and connected to the outer surface of the diversion pipe. Several nozzles are provided and connected to the lower ends of the multiple rinsing pipes. A connecting pipe is fixedly connected to the front end of the water pump. The water pump draws water through the connecting pipe and delivers it to each rinsing pipe through the water injection pipe and the diversion pipe. The nozzles rinse the raw materials after preliminary dust removal to remove residual stubborn impurities and dust, thus performing secondary dust removal.

[0008] Furthermore, the separation mechanism includes a enclosure, a screen is fixedly connected to the inner cavity of the enclosure, vibrators are fixedly connected to both the left and right ends of the enclosure, multiple buffers are fixedly connected to both the left and right ends of the enclosure, a discharge plate is fixedly connected to the rear end of the enclosure, and a removal component is fixedly connected to the lower ends of the multiple buffers. The vibrators drive the screen to vibrate at high frequency, which, in conjunction with the rinsing component, allows the raw material to be vibrated and screened on the screen, while being rinsed at the same time. Small particles of impurities and water fall through the screen into the removal component, while qualified raw material is output from the discharge plate. Furthermore, the impurity removal component includes an impurity removal box, a wedge plate is fixedly connected to the inner cavity of the impurity removal box, a filter screen is fixedly connected to the left and right walls of the inner cavity of the impurity removal box, a drain pipe is fixedly connected and connected to the inner surface of the impurity removal box, and a valve is provided on the outer surface of the drain pipe. Impurities and water falling into the impurity removal box are guided by the wedge plate. Water is filtered through the filter screen and discharged through the drain pipe, while impurities remain in the impurity removal box, achieving solid-liquid separation and facilitating subsequent cleaning. Furthermore, the impurity removal assembly also includes a baffle, the outer surface of which is slidably connected to the inner surface of the impurity removal box. A handle is fixedly connected to the upper end of the impurity removal box. When it is necessary to clean impurities, the baffle is pulled by the handle to remove the baffle from the impurity removal box, making it easier to remove solid impurities from the impurity removal box. Furthermore, the lower end of the water pump is fixedly connected to the upper end of the connecting plate, the upper ends of the multiple flushing pipes are fixedly connected to the lower end of the connecting plate, the upper end of the diverting pipe is fixedly connected to the lower end of the connecting plate, the rear end of the feed hopper is fixedly connected to the front end of the connecting plate, and the lower end of the feed hopper is fixedly connected to the upper ends of multiple connecting rods. Furthermore, the lower ends of multiple buffers are fixedly connected to the upper end of the impurity removal box, the upper end of the impurity removal box is fixedly connected to the lower ends of multiple connecting rods, and the upper end of the impurity removal box is fixedly connected to the lower ends of two support rods.

[0009] (1) This solution can effectively improve the cleanliness of raw materials through dust removal components. It can achieve preliminary air separation and dust removal by using a fan in conjunction with a buffer plate and a guide plate, which can remove most of the light dust and debris in the raw materials.

[0010] (2) This solution uses a rinsing component in conjunction with a separation mechanism to perform secondary water washing and dust removal on the raw materials after preliminary dust removal, and to remove residual impurities. By using a vibrating screen and rinsing in synergy, fine impurities and moisture can be further screened, which can more comprehensively remove impurities from the raw materials and improve the practicality of the equipment.

[0011] (3) This solution can separate impurities and wastewater generated during the dust removal process through the impurity removal component, which facilitates the subsequent cleaning of the equipment. Attached Figure Description

[0016] The present invention will be further described below with reference to the embodiments.

[0017] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-6 A dust removal and separation device for food processing includes multiple connecting rods 1. The upper ends of the multiple connecting rods 1 are fixedly connected to a dust removal mechanism 2. The lower part of the dust removal mechanism 2 is fixedly connected to two support rods 3.

[0018] The controller 24 uses a Siemens S7-200 SMART PLC (CPUSR20), which integrates PID control algorithm and supports touch screen HMI interface (7-inch color screen).

[0019] In this embodiment of the utility model, the dust removal component 23 is activated by the controller 24, and the wind power can be used to perform preliminary dust removal on the raw materials required for food processing, blowing away dust and debris; the separation mechanism 4 is controlled by the controller 24 to cooperate with the rinsing component 25 to perform secondary dust removal by using vibration and rinsing simultaneously, which can accurately clean the impurities and dust attached to each raw material, and separate them from the raw materials.

[0020] In some embodiments, such as Figure 2-4 As shown, in a preferred embodiment of the present invention, the dust removal assembly 23 includes a feeding hopper 231. The rear end of the feeding hopper 231 is fixedly connected to the front end of the connecting plate 21. The lower end of the feeding hopper 231 is fixedly connected to the upper ends of multiple connecting rods 1. An output pipe 232 is fixedly connected to the front end of the feeding hopper 231. Multiple buffer plates 233 are fixedly connected to the inner cavity of the feeding hopper 231. A fan 234 is fixedly connected to the rear end of the feeding hopper 231. The lower end of the fan 234 is fixedly connected to the upper end of the pad block 22. A guide plate 235 is fixedly connected to the inner cavity of the feeding hopper 231.

[0021] Fan 234 uses an ABBZA100 centrifugal fan with variable frequency speed control (380V / 50Hz, power 5.5kW). It optimizes airflow distribution through adjustable guide vanes to achieve efficient separation of more than 95% of light impurities. The rinsing assembly 25 includes a water pump 251. The lower end of the water pump 251 is fixedly connected to the upper end of the connecting plate 21. The output end of the water pump 251 is fixedly connected to a water injection pipe 252. The outer surface of the water injection pipe 252 is fixedly connected to and connected to a diversion pipe 253. The upper end of the diversion pipe 253 is fixedly connected to the lower end of the connecting plate 21. The outer surface of the diversion pipe 253 is fixedly connected to and connected to multiple rinsing pipes 254. The upper ends of the multiple rinsing pipes 254 are all fixedly connected to the lower end of the connecting plate 21. The lower ends of the multiple rinsing pipes 254 are all provided with and connected to several nozzles. The front end of the water pump 251 is fixedly connected to a connecting pipe 255.

[0022] The water pump 251 uses a Grundfos CR3-6 multistage centrifugal pump, made of 316L stainless steel, which is resistant to acid and alkali corrosion. Combined with pulse control technology (pressure fluctuation ≤ ±0.02MPa), it ensures that the atomization uniformity of the nozzle is ≥98%. The nozzle is a Spray SS1 / 4-SS+6510 with a fan-shaped spray pattern (spray angle 65°), a removable anti-clogging filter (0.5mm pore size), and a working pressure range of 0.2-0.8MPa.

[0023] In this embodiment of the utility model, before the equipment is started, the operator sets the operating parameters for dust removal, rinsing and vibration through the controller 24. Based on the characteristics of corn kernel raw materials, the speed of the fan 234 is set to 1200-1500 r / min, the water pressure of the water pump 251 is adjusted to 0.3-0.5 MPa, and the frequency of the vibrator 43 is set to 50-60 Hz.

[0024] During operation, corn kernels are poured in at a constant speed from the top of the feed hopper 231. As the kernels fall, they first collide with the buffer plate 233 to slow down, extending the contact time with the airflow generated by the blower 234. The controller 24 starts the blower 234 according to preset parameters. The strong airflow blows the light dust, corn silk, and other debris adhering to the surface of the corn kernels out from the output pipe 232, completing the initial dust removal. After the initial dust removal, the corn kernels slide down along the guide plate 235 and are evenly dispersed into the screen 42 under the guiding action of the guide plate 235, avoiding local accumulation that would affect the screening effect.

[0025] In some embodiments, such as Figure 5-6 As shown, in a preferred embodiment of the present invention, the separation mechanism 4 includes a barrier 41, a screen 42 fixedly connected to the inner cavity of the barrier 41, a vibrator 43 fixedly connected to both the left and right ends of the barrier 41, a plurality of buffers 44 fixedly connected to both the left and right ends of the barrier 41, the lower ends of the plurality of buffers 44 fixedly connected to the upper end of the impurity removal box 461, a discharge plate 45 fixedly connected to the rear end of the barrier 41, and an impurity removal component 46 fixedly connected to the lower ends of the plurality of buffers 44.

[0026] The vibrator 43 is model OliV1-70 / 100, adopts a double eccentric block design, has an excitation force of 800N, stepless speed regulation (0-3000r / min), protection level of IP66, and is compatible with screen 42 with an amplitude range of 2-5mm. The model of the shock absorber 44 is ACESC330M. It adopts hydraulic damping buffer, with a maximum stroke of 30mm and a rated load of 1500N. It can absorb more than 90% of vibration energy and extend the service life of the equipment.

[0027] The impurity removal assembly 46 includes an impurity removal box 461. The upper end of the impurity removal box 461 is fixedly connected to the lower end of multiple connecting rods 1. The upper end of the impurity removal box 461 is fixedly connected to the lower end of two support rods 3. A wedge plate 462 is fixedly connected to the inner cavity of the impurity removal box 461. A filter screen 463 is fixedly connected to the left and right walls of the inner cavity of the impurity removal box 461. A drain pipe 464 is fixedly connected to and communicates with the inner surface of the impurity removal box 461. A valve 465 is provided on the outer surface of the drain pipe 464.

[0028] The impurity removal assembly 46 also includes a baffle 466, the outer surface of which is slidably connected to the inner surface of the impurity removal box 461, and a handle is fixedly connected to the upper end of the impurity removal box 461.

[0029] In this embodiment of the invention, after the corn kernels fall into the screen 42, the controller 24 simultaneously starts the vibrator 43 and the water pump 251. The vibrator 43 drives the screen 42 to vibrate at high frequency with the cooperation of multiple buffers 44, causing the corn kernels to tumble and move on the screen 42. During this process, residual small particles of impurities are separated from the corn kernels due to vibration. At the same time, the water pump 251 draws water and distributes it to the rinsing pipe 254 through the water injection pipe 252 and the diversion pipe 253. The nozzle sprays out a fan-shaped water mist to rinse the corn kernels 360 degrees. The small particles of impurities and sewage fall through the screen 42 into the impurity removal box 461. The wedge plate 462 guides the sewage to the filter screen 463. After filtration by the filter screen 463, the operator can open the drain pipe 464 valve 465 in a timely manner according to the sewage volume to discharge the filtered sewage, while the impurities remain in the box. The corn kernels that have completed dust removal, rinsing and screening are output from the discharge plate 45 and can be collected in a prepared container.

[0030] After the equipment is used, the baffle 466 can be pulled open using the handle to remove the baffle 466 from the impurity removal box 461, making it easier to clean the impurities accumulated in the impurity removal box 461 from above.

[0031] It should be noted that the controller 24, vibrator 43, fan 234, and water pump 251 in this utility model are powered by a power source, and the vibrator 43, fan 234, and water pump 251 are controlled by the controller 24.

[0032] It should be noted that the specific installation methods, circuit connection methods, and control methods of the controller 24, vibrator 43, fan 234, and water pump 251 in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0033] Working principle: After the raw material is poured into the feed hopper 231, its descent speed is reduced under the action of the buffer plate 233, creating conditions for subsequent dust removal. After the fan 234 is started, it generates a strong airflow, forming a specific flow field in the feed hopper 231. Light dust and debris, due to their small mass and low inertia, are easily altered in their motion state under the action of the airflow, and are thus blown towards the output pipe 232 for discharge, achieving preliminary dust removal.

[0034] After initial dust removal, the corn kernels slide down along the guide plate 235 and are evenly dispersed into the screen 42 under the guiding action of the guide plate 235, avoiding local accumulation that would affect the screening effect. After the vibrator 43 is started, it drives the screen 42 to vibrate at high frequency. During this process, the raw material and the screen 42 collide and rub against each other continuously. Small particles of impurities, because their size is smaller than the aperture of the screen 42, pass through the screen 42 and fall down under the action of vibration and gravity. However, qualified raw materials, because their size is larger, cannot pass through the screen 42 and continue to move on the screen 42, and are finally output from the discharge plate 45.

[0035] During this process, the water pump 251 draws water from the source through the connecting pipe 255. The pressure of the water pump 251 causes the water to flow through the water injection pipe 252 and the diversion pipe 253, and is evenly distributed to multiple flushing pipes 254. Finally, the water is sprayed out at high speed from the nozzle. In conjunction with the screen 42, it can not only assist in flushing the raw materials, but also carry small particulate impurities through the screen 42 quickly. While performing secondary dust removal, it can also quickly separate impurities from qualified raw materials, thereby improving separation efficiency.

[0036] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
