Description

Technical Field

[0001] This application relates to the field of food processing technology, and in particular to a combined removal device for metal foreign objects in food. Background Technology

[0002] The published patent CN207723062U discloses an automatic food sieving device for removing metal foreign objects. The device includes a stirring chamber, a stirring shaft, a conveyor belt, a sieving box, a sieving motor, a sieving chamber, and a collection chamber. A metal detection device is installed on the conveyor belt. This invention uses a conveyor belt with a metal detection device integrating detection and removal functions to remove metal foreign objects. After the food undergoes an initial removal process, it enters the sieving box. The sieving box uses the vibration of the sieving motor to sieve the food, removing large particles. Finally, a secondary sieve and bar magnet work together to perform a second sieving of the food and a second removal of metal. Compared with existing technologies, this device offers better food sieving results and can automatically remove metal components from food. It features a simple structure, high automation, and strong practicality, making it particularly suitable for sieving powdered and granular foods.

[0003] The device in the aforementioned patent uses magnets to attract metal foreign objects when screening them. However, the magnets' S-shaped sliding trajectory may not be ideal for screening metal foreign objects. The magnets cover a small area inside the food, which means that metal foreign objects inside the food cannot be completely removed, reducing the efficiency of foreign object screening, affecting food quality, and thus reducing the practicality of the device.

[0004] Therefore, this application proposes a combined removal device for metal foreign objects in food. Utility Model Content

[0005] This application proposes a combined metal foreign object removal device for food to solve the problems mentioned in the background art. This combined metal foreign object removal device for food, by setting up an adsorption mechanism, baffle, rotating rod, transmission roller, magnetic conveyor belt, crossbar, metal brush, connecting block and collection box, can greatly improve the screening efficiency of metal impurities, avoid the problem of insufficient screening of metal impurities inside the raw materials, and greatly improve the practicality of the device.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] A combined metal foreign object removal device for food includes a conveyor box, a feeding structure at the top of the conveyor box, a stirring mechanism inside the conveyor box, an adsorption mechanism on one side of the conveyor box, the adsorption mechanism including a baffle fixedly connected to the stirring mechanism, a rotating rod rotatably connected to the inner side of the baffle, a transmission roller fixedly connected to the outer side of the rotating rod, a magnetic conveyor belt drivingly connected to the outer side of the transmission roller, a crossbar fixedly connected to the bottom of the baffle, a metal brush mounted on the top of the crossbar and in contact with the bottom surface of the magnetic conveyor belt, connecting blocks fixedly connected to both sides of the bottom of the baffle, a collection box fixedly connected to the bottom of the connecting blocks, a receiving structure on one side of the adsorption mechanism, a filtering structure inside the receiving structure, a secondary screening structure inside the receiving structure, a discharging structure at the bottom of the receiving structure, and an inspection structure on the outer side of the receiving structure.

[0008] In a preferred embodiment, the feeding structure includes a feeding cylinder, which is fixedly connected to the top of the conveying box. The feeding cylinder extends into the interior of the conveying box, and a buffer inclined plate is fixedly connected to the inner wall of the top of the conveying box.

[0009] Food ingredients are fed into the conveyor box through the feeding cylinder. After entering the conveyor box, they fall onto the buffer ramp. The buffer ramp reduces the amount of ingredients falling to the bottom and prevents them from accumulating, thus improving the practicality of the device.

[0010] In a preferred embodiment, the stirring mechanism includes a motor, which is fixedly connected to one side of the conveyor box. The output end of the motor extends into the interior of the conveyor box, and a stirring rod is fixedly connected to the output end of the motor. A conveying plate is fixedly connected to the other side of the conveyor box, and the conveying plate communicates with the conveyor box.

[0011] The device uses a motor to drive a stirring rod to rotate, which stirs the falling raw materials and transports them to the right side of the conveyor box. Finally, the fully stirred raw materials are conveyed to the outside through a conveyor plate for the next process, thus improving the practicality of the device.

[0012] In a preferred embodiment, the receiving structure includes a receiving box, which is placed on one side of the collection box. A receiving tube is fixedly connected to the top of the receiving box, and the receiving tube extends into the interior of the receiving box.

[0013] The screened raw materials are collected in the receiving cylinder and fall into the receiving box, which facilitates subsequent operations and improves the practicality of the device.

[0014] In a preferred embodiment, the filter structure includes a coarse filter plate, which is fixedly connected to the inner walls of both sides of the receiving box. A fine filter plate is fixedly connected to the inner walls of both sides of the receiving box, and the fine filter plate is located at the bottom of the coarse filter plate.

[0015] The raw material, after metal removal, undergoes preliminary filtration through a coarse filter plate, which removes larger impurities. Then, it undergoes secondary filtration through a fine filter plate, which removes smaller impurities. These two filtration steps remove impurities other than metals from the raw material, improving its quality and thus enhancing the practicality of the equipment.

[0016] In a preferred embodiment, the secondary screening structure includes a C-shaped rod, which is slidably connected to the receiving box. A pull ring is fixedly connected to one side of the C-shaped rod, and a magnetic screen is fixedly connected to the other side of the C-shaped rod. The other side of the magnetic screen is in contact with the left side wall of the receiving box.

[0017] The filtered raw material is screened again for metal impurities by two layers of magnetic screens, avoiding any missed screenings from the initial screening. Pulling the pull ring allows the magnetic screens to be pulled out for easy cleaning of metal impurities, thus improving the practicality of the device.

[0018] In a preferred embodiment, the feeding structure includes a feeding cylinder, which is fixedly connected to the bottom of the receiving box. The feeding cylinder extends into the interior of the receiving box, and a cap is threaded to the bottom of the feeding cylinder.

[0019] The processed raw materials can be collected by opening the cover and then transported to the outside through the feeding cylinder, thereby improving the practicality of the device.

[0020] In a preferred embodiment, the inspection structure includes an inspection door, which is hinged to the receiving box, and a handle is installed on the outer surface of the inspection door;

[0021] The inspection door can be opened by pulling the handle, making it easy to inspect the internal structure of the receiving box and to carry out timely maintenance and replacement of the internal structure, thereby improving the practicality of the device.

[0022] The beneficial effects of this application are:

[0023] 1. This combined metal foreign object removal device for food, by setting up an adsorption mechanism, baffle, rotating rod, transmission roller, magnetic conveyor belt, crossbar, metal brush, connecting block and collection box, can greatly improve the screening efficiency of metal impurities. The stirring rod continuously and in small quantities transports raw materials to the top of the magnetic conveyor belt through the conveyor plate. The magnetic conveyor belt is driven by the rotation of the transmission roller. Due to the inherent characteristics of the magnetic conveyor belt, it can adsorb metal impurities inside the raw materials. When it is driven to the right, the raw materials fall, while the metal impurities continue to be adsorbed on the surface of the magnetic conveyor belt. When it is driven to the crossbar, the metal brush scrapes off the metal impurities adsorbed on the surface of the magnetic conveyor belt and collects them inside the collection box. Therefore, the magnetic conveyor belt can cyclically screen the raw materials for metal impurities and avoid the problem of insufficient screening of metal impurities inside the raw materials, which greatly improves the practicality of the device.

[0024] 2. This food metal foreign object removal device, by setting a secondary screening structure, C-shaped rod, pull ring and magnetic screen, can screen out metal impurities from raw materials twice. The metal impurities are screened out again from the filtered raw materials by two layers of magnetic screen, avoiding the situation of missed screening in the first screening. Moreover, pulling the pull ring can pull out the magnetic screen, which is convenient for cleaning metal impurities, greatly improving the practicality of the device. Attached Figure Description

[0032] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0033] Reference Figure 1-2 A combined metal foreign object removal device for food includes a conveyor box 1. The top of the conveyor box 1 is provided with a feeding structure 2, which includes a feeding cylinder 21. The feeding cylinder 21 is fixedly connected to the top of the conveyor box 1 and extends into the interior of the conveyor box 1. A buffer inclined plate 22 is fixedly connected to the inner wall of the top of the conveyor box 1. Food raw materials are fed into the conveyor box 1 through the feeding cylinder 21 and fall onto the buffer inclined plate 22 after entering the conveyor box 1. The buffer inclined plate 22 can reduce the amount of raw materials falling to the bottom and prevent the raw materials from accumulating, thereby improving the practicality of the device.

[0034] Reference Figure 1-2 The conveying box 1 is equipped with a stirring mechanism 3, which includes a motor 31.

A stirring rod 32 is fixedly connected to the output end of the motor 31. A conveying plate 33 is fixedly connected to the other side of the conveying box 1, and the conveying plate 33 is connected to the conveying box 1. The stirring rod 32 is driven by the motor 31 to rotate, thereby stirring the falling raw materials and transporting them to the right side of the conveying box 1. Finally, the fully stirred raw materials are transported to the outside through the conveying plate 33 for the next process, thereby improving the practicality of the device.

[0035] Reference Figure 1 , 34. An adsorption mechanism 4 is provided on one side of the conveying box 1.

A crossbar 45 is fixedly connected to the bottom of the baffle 41. A metal brush 46 is installed on the top of the crossbar 45 and contacts the bottom surface of the magnetic conveyor belt 44. Connecting blocks 47 are fixedly connected to both sides of the bottom of the baffle 41. A collection box 48 is fixedly connected to the bottom of the connecting blocks 47.

[0036] Reference Figure 1 , 5 The adsorption mechanism 4 is provided with a receiving structure 5 on one side. The receiving structure 5 includes a receiving box 51, which is placed on one side of the collection box 48. A receiving cylinder 52 is fixedly connected to the top of the receiving box 51 and extends into the interior of the receiving box 51. The raw material after screening is received by the receiving cylinder 52 and falls into the receiving box 51, which facilitates subsequent operations and improves the practicality of the device.

[0037] Reference Figure 1 , 5 The receiving structure 5 has an internal filtration structure 6, which includes a coarse filter plate 61 fixedly connected to the inner walls of both sides of the receiving box 51. A fine filter plate 62 is fixedly connected to the inner walls of both sides of the receiving box 51, and the fine filter plate 62 is located at the bottom of the coarse filter plate 61. The raw material after metal removal is initially filtered by the coarse filter plate 61, which removes larger impurities from the raw material. Then, the raw material is filtered a second time by the fine filter plate 62, which removes smaller impurities. Through these two filtration steps, impurities other than metal impurities in the raw material can be filtered out, improving the quality of the raw material and thus enhancing the practicality of the device.

[0038] Reference Figure 1 , 5 The receiving structure 5 is equipped with a secondary screening structure 7. The secondary screening structure 7 includes a C-shaped rod 71, which is slidably connected to the receiving box 51. A pull ring 72 is fixedly connected to one side of the C-shaped rod 71, and a magnetic screen 73 is fixedly connected to the other side of the C-shaped rod 71. The other side of the magnetic screen 73 is in contact with the left side wall of the receiving box 51. The filtered raw material is screened again for metal impurities through the two layers of magnetic screens 73, avoiding the situation of missed screening in the first screening. Pulling the pull ring 72 can pull out the magnetic screen 73, which is convenient for cleaning metal impurities, thereby improving the practicality of the device.

[0039] Reference Figure 1 , 5The bottom of the receiving structure 5 is provided with a feeding structure 8, which includes a feeding cylinder 81 and is fixedly connected to the bottom of the receiving box 51. The feeding cylinder 81 extends into the interior of the receiving box 51, and a cover 82 is threadedly connected to the bottom of the feeding cylinder 81. By opening the cover 82, the processed raw materials can be collected and transported to the outside through the feeding cylinder 81, thereby improving the practicality of the device.

[0040] Reference Figure 1 , 6 An inspection structure 9 is provided on the outside of the receiving structure 5. The inspection structure 9 includes an inspection door 91, which is hinged to the receiving box 51. A handle 92 is installed on the outer surface of the inspection door 91. The inspection door 91 can be opened by pulling the handle 92, which facilitates the inspection of the internal structure of the receiving box 51 and the timely maintenance and replacement of the internal structure, thereby improving the practicality of the device.

[0041] Working principle: When the device is working, the food raw materials are fed into the conveyor box 1 through the feed cylinder 21. After entering the conveyor box 1, they fall onto the buffer inclined plate 22. The buffer inclined plate 22 can reduce the amount of raw materials falling to the bottom and prevent the raw materials from accumulating. The motor 31 drives the stirring rod 32 to rotate, thereby stirring the falling raw materials and transporting them to the right side of the conveyor box 1. Finally, the fully stirred raw materials are transported to the outside through the conveyor plate 33. The stirring rod 32 uses small amounts of raw materials to continuously transport them through the conveyor plate 33 to the top of the magnetic conveyor belt 44. The magnetic conveyor belt 44 is driven by the rotation of the transmission roller 43. Due to the inherent characteristics of the magnetic conveyor belt 44, it can adsorb metal impurities inside the raw materials. When it is driven to the right side, the raw materials fall, while the metal impurities continue to be adsorbed on the surface of the magnetic conveyor belt 44. When it is driven to the crossbar 45, the metal brush 46 scrapes off the metal impurities adsorbed on the surface of the magnetic conveyor belt 44 and collects them inside the collection box 48.

[0042] Then, the screened raw material is collected by the receiving cylinder 52 and falls into the receiving box 51. The raw material after metal removal is initially filtered by the coarse filter plate 61 to remove larger impurities. Then, it is filtered a second time by the fine filter plate 62 to remove smaller impurities. Through these two filtration steps, other impurities besides metal impurities can be filtered out. The filtered raw material is then screened again by two layers of magnetic screens 73 to remove metal impurities, avoiding any missed screenings from the first screening. Pulling the pull ring 72 can pull out the magnetic screens 73 for easy cleaning of metal impurities.

[0043] Finally, opening the cover 82 allows the processed raw materials to be collected and transported to the outside via the discharge cylinder 81. Pulling the handle 92 opens the inspection door 91, facilitating the inspection of the internal structure of the receiving box 51 and enabling timely maintenance and replacement of the internal structure.
