Description

Technical Field

[0001] The utility model relates to the technical field of feed processing, in particular to a metal detection device for scraps. Background Art

[0002] The most commonly used raw materials in fish feed processing are fish meal and fish oil, and fish meal and fish oil are mainly extracted from fish meat. The fish meat used by the raw material processing plant will be selected from the scraps of fish sold in the market, which can not only reduce the production and processing costs, but also help fishermen or the market digest excess scraps. Before the scraps are processed into fish meal and fish oil, the impurities contained in them need to be removed, including detecting whether the scraps contain metals. At present, the commonly used metal detection method is mostly to convey the scraps under the metal detector, and an alarm will be issued after the metal is detected. Then, the scraps containing metals are manually selected to avoid the subsequent processed fish meal or fish oil containing metals that are harmful to fish. In the above method, the efficiency of manual selection is low and the labor intensity of the staff is high. Therefore, some manufacturers have introduced automatic rejection equipment. However, during automatic rejection, due to the slowness of the rejection equipment, some scraps that do not contain metals will be rejected at the same time, and the metal content of the scraps is high, which increases the production cost.

DETAILED DESCRIPTION

[0020] In order to better understand the technical content of the present invention, a specific embodiment is provided below, and the present invention is further described in conjunction with the accompanying drawings.

[0021] See also Figures 1 to 3 The utility model provides a scrap metal detection device, including a conveyor belt 1, a detection chamber 2, a detection coil 3, a host computer 4 and a rejection mechanism, wherein a rejection chamber 5 is formed between the conveyor belts 1, the detection chamber 2 is arranged above one of the conveyor belts 1, and the detection coil 3 is arranged on the top surface of the detection chamber 2; the rejection mechanism includes a mounting plate 6, an electric slide 7, a rotating motor 8, a horizontal plate 9 and a vertical plate 10, the mounting plate 6 is arranged on both sides of the rejection chamber 5, and its two ends are connected to the side walls of the conveyor belt 1, the horizontal plate 9 is located in the rejection chamber 5, the top of the vertical plate 10 is connected to one side of the horizontal plate 9, the electric slide 7 is arranged on the side wall opposite to the mounting plate 6, the rotating motor 8 is arranged on the side wall of the mover of the electric slide 7, and its output shaft is connected to the side wall of the vertical plate 10; the host computer 4 is arranged on one side of the conveyor belt 1, and is electrically connected to the detection coil 3, the electric slide 7 and the rotating motor 8 respectively.

[0022] The utility model discloses a waste metal detection device, which is used for detecting fish waste. The waste to be processed is placed on a conveyor belt 1 for conveying. The waste will first pass through a detection chamber 2. A detection coil 3 is arranged inside the detection chamber 2 to generate a magnetic field. When the waste contains metal, the magnetic field generated by the detection coil 3 will change, and an upper computer 4 can judge whether the waste contains metal according to the change of the magnetic field. When the waste containing metal moves onto a horizontal plate 9, the upper computer 4 can start a rotating motor 8, which can drive the horizontal plate 9 and the vertical plate 10 to rotate. The waste on the horizontal plate 9 will slide downward and slide down from a rejection chamber 5 for rejection, thereby realizing the rejection of waste containing metal, and avoiding the subsequent processed fish meal and fish oil containing metal, which will cause the prepared fish feed to harm farmed fish.

[0023] While the horizontal plate 9 rotates downward for rejection, the vertical plate 10 will rotate upward, and the electric slide 7 drives the rotating motor 8 to move horizontally, so that the vertical plate 10 can be laid flat in the rejection chamber 5, and finally the vertical plate 10 becomes horizontal. The scraps that do not contain metal can be transported to another conveyor belt 1 through the top of the vertical plate 10 under the action of the conveyor belt 1, and finally transported to the subsequent process for fish meal and fish oil extraction. When there are still scraps containing metal moving to the horizontal vertical plate 10, the upper computer 4 can control the rotating motor 8 to reverse and rotate the vertical plate 10 downward, so that the scraps can be rejected from the rejection chamber 5. At the same time, the horizontal plate 9 will return to a horizontal state and be laid flat in the rejection chamber 5, so as to realize intermittent rejection. Since the rejection chamber 5 will be filled by the horizontal plate 9 or the vertical plate 10 during rejection, it is possible to prevent the scraps that do not contain metal from falling from the rejection chamber 5, thereby avoiding an increase in production costs.

[0024] Preferably, it further comprises a recycling mechanism, wherein the recycling mechanism comprises a recycling box 11 , and the recycling box 11 is arranged below the rejection chamber 5 .

[0025] The scraps dropped from the rejection chamber 5 will fall into the recovery box 11, and the metal-containing scraps can be recovered through the recovery box 11, so as to facilitate re-detection of whether there is metal after crushing.

[0026] Preferably, the recycling mechanism further includes an auger 12 , which is disposed inside the recycling box 11 , and the host computer 4 is electrically connected to the auger 12 . The recycling mechanism further includes a cutting knife 13 , which is disposed on an outer wall of the auger 12 .

[0027] Since the scraps will fall from both sides of the rejection chamber 5 in turn, an auger 12 is provided in the recycling box 11. The auger 12 can transport the scraps to the middle of the recycling box 11 to prevent the scraps from accumulating on both sides of the recycling box 11. In addition, the cutting knife 13 on the auger 12 can chop the scraps, so that metal detection can be performed on small-sized scraps.

[0028] Preferably, the rejection mechanism further includes a rotating shaft 14 , which is disposed at the joint of the vertical plate 10 and the horizontal plate 9 , and the output shaft of the rotating motor 8 is connected to the end of the rotating shaft 14 .

[0029] The rotating motor 8 realizes the rotation of the vertical plate 10 and the horizontal plate 9 through the rotating shaft 14, thereby realizing the removal of metal-containing scraps and the transportation of non-metal-containing scraps.

[0030] Preferably, the rejection mechanism further includes a connecting rod 15 , which is disposed on both sides of the mounting plate 6 and forms a U-shaped structure with the mounting plate 6 , and the connecting rod 15 is connected to the side wall of the conveyor belt 1 .

[0031] The connecting rod 15 is used to support the mounting plate 6 to ensure that there is a distance between the mounting plate 6 and the rejection chamber 5 to facilitate the installation of the electric slide 7 and the rotating motor 8, and to ensure that the horizontal plate 9 and the vertical plate 10 are completely laid flat in the rejection chamber 5.

[0032] Preferably, the rejection mechanism further includes a weighing sensor 16 , which is disposed on the horizontal plate 9 and the vertical plate 10 , and the host computer 4 is electrically connected to the weighing sensor 16 .

[0033] The provided weighing sensor 16 is used to detect whether there are scraps on the horizontal plate 9 and the vertical plate 10. The upper computer 4 controls the rotating motor 8 and the electric slide 7 to remove the scraps according to the weight information and the metal detection information.
