Description

Technical Field

[0001] This utility model relates to the technical field of oil residue separation equipment, and in particular to an animal carcass oil residue separation device. Background Technology

[0002] In the existing process of harmless treatment of animal carcasses, especially in the extraction of oil through high-temperature rendering, oil residue separation is a key step.

[0003] In practical applications, existing equipment typically suffers from the following problems: Existing static separation methods tend to cause oil residue to clump together, preventing the oil inside from being fully separated, resulting in low oil yield and high oil content in the residue, which affects subsequent utilization. High-temperature waste gas and water vapor are generated during the separation process. If they are discharged directly, they will cause environmental pollution and waste of heat. The solid residue after separation is often uneven in particle size and lacks subsequent fine screening steps, which affects its quality and value as feed raw material or fertilizer, thus causing many inconveniences.

[0004] Therefore, this utility model provides an animal carcass oil residue separation device. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an animal carcass oil residue separation device with high separation efficiency, capable of recovering waste gas and finely classifying oil residue.

Each limiting seat has an installation rod extending to the inner wall of the secondary screening box. The limiting seats and installation rods reinforce the secondary screening box and the bottom support frame, thereby improving the installation stability of the secondary screening box.

[0007] In a preferred embodiment, a discharge pipe is installed on one side of the oil-sludge separation box. A second valve is fixedly connected to the outside of the discharge pipe. The second valve is used to control the opening and closing of the discharge pipe. The discharge pipe is used for emergency depressurization of the oil-sludge separation box. A first mounting plate is fixedly connected inside the motor mounting bracket. A motor mounting plate is fixedly connected to the top of the first mounting plate. A first drive motor is fixedly connected to the top of the motor mounting plate. A drive pulley is fixedly connected to the output end of the first drive motor.

A driven pulley is rotatably connected inside the transmission belt and above the drive pulley. The driven pulley is connected to the drive pulley via the transmission belt. One side of the driven pulley is fixedly connected to one end of the drive shaft. This ensures that when the first drive motor is running, it drives the transmission belt, thereby driving the drive shaft to rotate and causing the internal exhaust pipe inside the internal heating cylinder to rotate, thus assisting in oil-sludge separation.

[0008] In a preferred embodiment, a side inspection cover is installed on the side of the oil-sludge separation box away from the dust cover. A first valve is installed on the outer side of the side inspection cover. One end of the internal air extraction pipe extends to the outside of the oil-sludge separation box and is connected to the first valve. The first valve is used to control the opening and closing of the internal air extraction pipe, thereby facilitating the discharge of waste gas from inside the oil-sludge separation box. One end of the first valve can be connected to an external recovery pipe for waste gas recovery and treatment, thereby purifying the working environment. A control panel is fixedly connected to the side of the oil-sludge separation box away from the discharge pipe. The first valve, the second valve, the first drive motor, the second drive motor, and the air pump are all electrically connected to the control panel. The control panel is used to control the operation of the first valve, the second valve, the first drive motor, the second drive motor, and the air pump, realizing unified management of electrical equipment.

[0009] In a preferred embodiment, a second mounting plate is fixedly connected inside the bottom support frame and below the secondary screening box.

The positioning bolts and the limit bearing seats cooperate to limit the installation of the drive shaft during operation, thereby improving the stability of the equipment during operation.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: By setting up an oil-sludge separation box, motor mounting frame, and bottom support frame, the material is uniformly heated through the cooperation of heating blocks and internal heating cylinders, causing the oil in the animal tissue to melt and precipitate. The first drive motor operates, and the stirring rod continuously agitates the material to prevent clumping, ensuring uniform heating and improving oil precipitation efficiency. Simultaneously, larger oil sludge lumps are mechanically broken down into smaller particles for easier subsequent separation and sieving. The molten liquid oil flows out through the sieving holes on the screening drum and enters the oil collection area of ​​the oil-sludge separation box, thus achieving initial separation of oil and sludge. An air pump generates negative pressure suction within the system through the conveying pipeline. This negative pressure draws out the dry, loose oil sludge particles remaining in the screening drum after initial separation, and... The waste gas and water vapor generated during the heating process are conveyed to the secondary screening box and can be drawn out through the internal exhaust pipe. By opening the first valve, these waste gases can be connected to the external recovery pipe for condensation, purification, and other treatments, avoiding environmental pollution and energy loss caused by direct discharge. The limit bearing seat and positioning bolts ensure the smooth operation of the drive shaft, while the limit seat and mounting rod ensure the installation stability of the secondary screening box in a vibrating working environment. This utility model improves the efficiency of primary separation and oil yield by combining internal heating with mechanical stirring and crushing, realizing the automated transfer of materials. The rotary centrifugal screening achieves fine classification of solid residues. Due to the waste gas recovery and safety pressure relief functions, the entire process is more efficient and safer.

[0020] Going further, such as Figures 1-4 , Figure 6 As shown, in this scheme, a second mounting plate 31 is fixedly connected inside the bottom support frame 3 and below the secondary screening box 4.

[0022] Working principle: like Figures 1-6 As shown: By setting up an oil-sludge separation box 1, a motor mounting bracket 2, and a bottom support bracket 3, and opening the control panel 11 during use, the control panel 11 is used to control the operation of the first valve 13, the second valve 15, the first drive motor 24, the second drive motor 49, and the air pump 46, realizing unified management of electrical equipment. The internal heating cylinder 52 has heating blocks evenly distributed on its inner wall. The heating blocks and the internal heating cylinder 52 work together to uniformly heat the material, causing the oil in the animal tissue to melt and precipitate. The first drive motor 24 operates, driving the drive shaft 55 to rotate through the driving pulley 25, the transmission belt 26, and the driven pulley 27. The drive shaft 55 drives the dispersing and stirring rod to rotate inside the ventilated pipe 53. The dispersing and stirring rod continuously agitates the material to prevent clumping. To ensure uniform heating of the material and improve oil extraction efficiency, larger oil residue lumps are mechanically broken up and crushed into smaller particles for easier subsequent separation and screening.

Waste gas and water vapor generated during heating can be extracted through the internal exhaust pipe 54. By opening the first valve 13, these waste gases can be connected to an external recovery pipe for condensation, purification, and other treatments, avoiding... To avoid environmental pollution and energy loss caused by direct discharge, the oil residue particles entering the secondary screening box 4 fall into the classification storage box 43. The second drive motor 49 starts, driving the rotating disk 42 to rotate multiple classification storage boxes 43 together. Under the centrifugal force generated by the rotation, oil residue particles of different sizes are thrown out through the screen holes of different sizes at the bottom of the classification storage box 43. The finest powder is screened out first and falls into the outermost recovery bin. Slightly larger particles are screened out in sequence in storage boxes 43 of different diameters. Finally, the oil residue is automatically and finely classified according to particle size. Different grades of oil residue can be used for different purposes. The classified oil residue is finally collected in the bottom recovery bin and can be temporarily stored in the on-site storage box 32 for convenient unified treatment. The discharge pipe 14 and the second valve 15 constitute an emergency pressure relief channel. When the internal pressure of the equipment rises abnormally, it can be manually or automatically opened to relieve pressure and ensure equipment safety. The limit bearing seat 28 and the positioning bolt 22 ensure the smooth operation of the drive shaft 55. The limit seat 47 and the mounting rod 48 ensure the installation stability of the secondary screening box 4 in a vibrating working environment. This utility model improves the efficiency and oil yield of primary separation by combining internal heating with mechanical stirring and crushing, and realizes the automated transfer of materials. The rotary centrifugal screening realizes the fine classification of solid residues. Due to the setting of waste gas recovery and safety pressure relief functions, the entire process is more efficient and safer.
