DETAILED DESCRIPTION

[0027] The present utility model will be further described in detail in combination with the drawings and specific embodiments.

[0028] As Figure 1 shown in the figure is the main structure principle diagram of the existing animal harmless oil pressing system, which comprises a raw material bin 1, a crusher 2, a preparation tank 3, a buffer bin 4 and an oil press 5. The dead animals are stored in the raw material bin 1, then conveyed to the crusher 2 by lifting and conveying equipment for crushing, then the materials are sent to the preparation tank 3 for disinfection and sterilization, then the materials are sent to the buffer bin 4, and the buffer bin 4 gradually conveys the materials to the oil press 5, and the oil press 5 realizes the separation of oil and residue.

[0029] Among them, the discharge port of the buffer bin 4 and the feeding port of the oil press 5 generally convey the materials through a conventional screw conveyor. As Figure 2 shown, the present embodiment provides a residue scraping mechanism of the animal harmless treatment oil pressing system, which is arranged between the oil outlet of the oil press 5 and the top feeding port of the buffer bin 4, and is used for re-feeding the oil residue carried in the crude oil generated by the oil press 5 into the buffer bin 4, mixing with the materials in the buffer bin 4, and then passing through the oil press 5 again for oil pressing, so as to avoid the generation of waste oil residue, improve the oil yield, and improve the automation degree of the entire animal harmless treatment process and the cleanliness of the factory area.

[0030] As Figure 2 and 3As shown, the slagging mechanism includes a housing 61, a sprocket 62, a chain 63, a scraper 64, and a motor 65. Since the slagging mechanism needs to transport oil residue from bottom to top, the housing is in the shape of "Z". A synchronous shaft is arranged at each of the upper and lower ends of the housing. The sprocket 62 is arranged at the two ends of the synchronous shaft. The chain 63 is connected between the sprockets at the upper and lower ends. The scraper 64 is arranged between the two chains 63. The motor 65 is in driving connection with one of the synchronous shafts. That is, the motor 65 drives the sprocket 62 and the chain 63 to move, and the chain 63 drives the plurality of scrapers 64 to move along the lower side of the housing from bottom to top, so as to gradually scrape the oil residue along the lower side of the housing 61 to the upper end of the housing and into the buffer bin. Since the oil residue is scraped from crude oil, the oil content is high. In order to improve the oil extraction efficiency and reduce the working pressure of the buffer bin and the oil press, a leaching port is arranged on the lower side of the housing 61. A screen 66 is arranged at the leaching port. Thus, the oil residue will pass through the screen during the upward transportation to leach part of the crude oil in the oil residue.

[0031] As shown in Figure 4 The scraper 64 is bent to form a mounting plate 641 on both sides. The chain 63 is provided with a connecting piece 631. The connecting piece 631 and the mounting plate 641 are connected by a bolt and a nut. This structure is more convenient for disassembly, maintenance, and assembly. In order to avoid the oil residue from being stuck between the housing 61 and the scraper 64, the distance between the head of the bolt and the nut is greater than the sum of the thicknesses of the connecting piece 631 and the mounting plate 641. That is, the scraper 64 is not fixedly connected with the connecting piece 631, but has a certain space for movement. Thus, when the oil residue is stuck between the scraper and the housing, the scraper can be lifted to ensure the smoothness of the transportation action and avoid damage to the equipment. In addition, the scraper 64 is provided with a baffle 642 at one end close to the middle of the housing. The baffle 642 can limit the oil residue scraped from the upper end of the scraper to ensure the transportation efficiency. On the other hand, the baffle 642 can extrude the oil residue to further drain the crude oil in the oil residue and reduce the working pressure of the buffer bin and the oil press.

[0032] As shown in Figure 2As shown, the shell has a "Z" shape structure, specifically including an inclined feeding section 611, a horizontal discharging section 612 and a horizontal feeding section 613 arranged at the upper and lower ends of the inclined feeding section respectively, wherein the horizontal feeding section 613 at the lower end is matched with the oil outlet of the oil press to directly receive the crude oil containing oil residue, the crude oil is discharged from the oil leakage port to the crude oil pool, and the oil residue is conveyed to the buffer bin by the scraper. In order to facilitate cooperation with the crude oil pool, the oil leakage port is arranged on the horizontal feeding section 613, and in order to enable the crude oil discharged during the upward conveying of the oil residue to quickly enter the crude oil pool, the oil leakage port is specifically arranged at the horizontal feeding section 613 close to the inclined feeding section 611. In order to reduce the influence of oil stains and other impurities on the motor, the motor 65 is arranged as high as possible, that is, on the upper side of the horizontal discharging section 612, and the lower side of the horizontal discharging section 612 is provided with a discharging port matched with the buffer bin.

[0033] Since the motor 65 is arranged at the upper end, the tensioning mechanism for tensioning the chain needs to be arranged at the two chain wheels at the lower end of the shell 61. Specifically, as shown in the figure, Figure 5 the tensioning mechanism includes a tensioning bracket 71, an adjusting plate 72, a bearing 73, a screw rod 74, a nut 75, and a positioning plate 76, the tensioning bracket 71 is provided with a guide groove along the length direction of the shell, the adjusting plate 72 is slidingly connected to the guide groove, the bearing 73 is arranged in the adjusting plate 72, the two chain wheels 62 are rotationally connected to the two bearings 73 through a synchronous shaft, one end of the screw rod 74 is connected to the adjusting plate 72, the other end of the two screw rods 74 is connected to the positioning plate 76 through the nut 75, and the positioning plate 76 abuts against the end of the shell 61; the side of the shell 61 is provided with a strip-shaped hole 611 matched with the movement of the synchronous shaft. In this way, by abutting the positioning plate 76 against the end of the shell 61, and then pulling the adjusting plate 72 by the positioning plate 76 through the screw rod 75, that is, pulling the chain wheel 62 at the end, the tensioning of the chain 63 is realized, and the connection position of the screw rod 74 and the positioning plate 76 can be adjusted through the nut 75 to adjust the tensioning degree. In addition, a bending portion 711 is arranged on the tensioning bracket 71 between the adjusting plate 72 and the positioning plate 76, the bending portion 711 is provided with a guide hole, and the screw rod 74 passes through the guide hole to improve the structural stability.

[0034] The above is only a preferred specific embodiment of the present application, which is one implementation under the overall concept of the present application, and the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
