Description

Technical Field

[0001] This utility model belongs to the field of feed processing technology, and in particular relates to an oil residue separation device for poultry and livestock feed processing. Background Technology

[0002] Feed is a general term for the food consumed by all domesticated animals. In a narrower sense, feed mainly refers to the food for animals raised in agriculture or animal husbandry (i.e., various types of poultry and livestock). Feed includes more than ten kinds of feed ingredients such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meals, whey powder, oils, meat and bone meal, grains, and feed additives. Adding oils to feed is a new technology that not only provides high energy but also increases feed intake, improves palatability, prevents dust generation during production, improves appearance, reduces mechanical wear, increases pellet feed production efficiency, provides essential fatty acids, and promotes the absorption and utilization of fat-soluble vitamins. However, before adding oils, they need to be processed. Oils are usually extracted from animal fats. The production of these oils is accompanied by some frying. If oil residue is mixed with the oil, it will affect the quality of the subsequent feed. Therefore, it is necessary to separate the oil from the oil residue. However, the following drawbacks still exist in the actual separation process:

[0003] 1. Conventional oil residue separation methods mostly rely on natural filtration. However, this method cannot completely separate the grease adhering to large amounts of oil residue. Therefore, a more efficient and thorough separation method is needed.

[0004] 2. Secondly, after a large amount of oil residue is separated from the grease, there will inevitably be a large amount of oil residue remaining. So how to quickly remove the oil residue and put in new oil residue is a problem. Frequent cleaning is too time-consuming. Utility Model Content

[0005] The purpose of this utility model is to provide an oil residue separation device for poultry and livestock feed processing. By setting up a separation tank, a separation cylinder, a rotating ring, and a filter disc, it solves the problems that conventional filtration and separation methods are insufficient to completely separate the oil from the oil residue, and that the next batch of oil residue cannot be quickly replaced after the oil is separated.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to an oil residue separation device for poultry and livestock feed processing, comprising a separation tank, a rotating ring, a separation cylinder, filter discs, and a threaded cylinder. The top of the separation tank is screwed on with a tank cover. A bearing is fixed to the upper part of the inner wall of the separation tank. A frustum is fixed to the inner bottom of the separation tank, and a rotatably connected limiting component is provided on the frustum. A rotating ring is rotatably connected inside the bearing. A separation cylinder is inserted into the rotating ring. A cross-shaped frame is fixed to the bottom of the separation cylinder. A central column is fixed to the inner bottom of the separation cylinder, and filter discs are evenly distributed around the central column. A through sleeve is fixed to the bottom of each filter disc, and both the sleeve and the filter disc are fitted outside the central column and placed inside the cavity of the separation cylinder.

[0008] Furthermore, the outer circumferential surface of the separator is fixed with legs arranged in a ring array, and an oil outlet pipe is fixed through the bottom of the separator outside the edge of the frustum.

[0009] Furthermore, a motor is fixed at the bottom center of the separation tank, and the output axis of the motor passes through the separation tank and the frustum and is fixed to the limiting member. The bottom of the cross-shaped frame is provided with a limiting groove that fits with the limiting member, and the limiting member is engaged in the limiting groove.

[0010] Furthermore, the inner wall of the rotating ring is provided with slots arranged in a ring array, and the upper part of the outer wall of the separating cylinder is fixed with blocks arranged in a ring array, and the blocks are engaged in the corresponding slots, the depth of the slots being less than the height of the rotating ring.

[0011] Furthermore, the filter disc has a large number of equally spaced filter holes, and the inner diameter of the filter disc is smaller than the inner diameter of the separation cylinder cavity.

[0012] Furthermore, the upper part of the central column is threadedly connected to a threaded cylinder, and a handwheel is fixed to the outer periphery of the threaded cylinder. The bottom end of the threaded cylinder abuts against the surface of the uppermost filter disc.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model solves the problem that conventional filtration methods are insufficient to completely separate oil from oil residue by setting up a separation tank, a separation cylinder, a rotating ring, and filter discs. The oily residue is placed in the separation cylinder, and multiple filter discs are used to separate the oil residue into layers, preventing all the oil residue from accumulating at the bottom of the separation cylinder. In this way, a certain amount of oil residue accumulates between every two filter discs, which helps with the layered oil filtration operation. The separation cylinder is then placed in the rotating ring in the separation tank and locked in place. The cross-shaped frame at the bottom of the separation cylinder also fits with the limiting block. Therefore, the motor drives the limiting block to rotate the separation cylinder, thereby creating a centrifugal effect on the oil residue in the separation cylinder and realizing the centrifugal separation oil filtration operation.

[0015] 2. This utility model solves the problem of not being able to quickly replace the next batch of oil residue after the oil residue has been separated by setting up a separation cylinder and a rotating ring. After a batch of oil is separated by frying, the entire separation cylinder can be moved up and taken out directly, and a new separation cylinder filled with oil residue can be replaced. There is no need to clean the oil residue frequently, and the oil residue raw material can be prepared outside, which greatly saves separation time and increases efficiency.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Please see Figure 1-9As shown, this utility model is an oil residue separation device for poultry and livestock feed processing, including a separation tank 1, a rotating ring 2, a separation cylinder 3, filter discs 4, and a threaded cylinder 5. The top of the separation tank 1 is screwed with a tank cover 101. A bearing 105 is fixed to the upper part of the inner wall of the separation tank 1. A frustum 106 is fixed to the inner bottom of the separation tank 1. A limiting member 1061 is provided on the frustum 106 for rotational connection. The rotating ring 2 is rotatably connected inside the bearing 105. The separation cylinder 3 is inserted into the rotating ring 2. A cross-shaped frame 303 is fixed to the bottom of the separation cylinder 3. A central column 301 is fixed to the inner bottom of the separation cylinder 3. The central column 301 is surrounded by filter discs 4 distributed at equal intervals. Each filter disc 4 has a through sleeve 401 fixed to its bottom. The sleeve 401 and the filter disc 4 are both sleeved outside the central column 301 and set in the inner cavity of the separation cylinder 3.

[0030] The separator 1 serves as a container for separating oil and grease. Inside, oil and grease are separated from grease and sludge. The oily grease is placed inside the separator 3, and then the filter disc 4 and the sleeve 401 are fitted around the central column 301 to create equal space on the top and bottom of the filter disc 4. This allows for the layering of oily grease and sludge. After a certain amount of layering, the separator 3 is inserted into the rotating ring 2. Finally, by rotating the separator 3 and the rotating ring 2, the oily grease and sludge in the separator 3 can be centrifugally separated.

[0031] Support legs 102 arranged in a ring array are fixed on the outer peripheral surface of the separator tank 1, and an oil outlet pipe 103 is fixed through the bottom of the separator tank 1 outside the edge of the frustum 106.

[0032] The separator tank 1 is supported by the support leg 102 to keep it stable. The grease filtered out in the separator cylinder 3 is finally discharged from the oil storage tank. With the design of the frustum 106, the grease will not accumulate in the center of the separator tank 1, but will be introduced into the oil pipe 103 along the inclined surface of the frustum 106.

[0033] A motor 104 is fixed at the bottom center of the separator 1, and the output shaft of the motor 104 passes through the separator 1 and the frustum 106 and is fixed to the limiting member 1061. The bottom of the cross-shaped frame 303 is provided with a limiting groove 3031 that fits with the limiting member 1061, and the limiting member 1061 is snapped into the limiting groove 3031.

[0034] The motor 104 drives the limiting member 1061 to rotate. The limiting member 1061 is engaged in the limiting groove 3031, which in turn drives the cross-shaped frame 303 and the separating cylinder 3 to rotate. The upper part of the separating cylinder 3 is engaged with the rotating ring 2 to maintain stability during rotation. The rotation of the separating cylinder 3 is driven to achieve the effect of centrifugal separation of grease inside.

[0035] The inner wall of the rotating ring 2 is provided with slots 201 arranged in a ring array, and the upper part of the outer wall of the separating cylinder 3 is fixed with blocks 302 arranged in a ring array, and the blocks 302 are engaged in the corresponding slots 201. The depth of the slots 201 is less than the height of the rotating ring 2.

[0036] When installing the separator cylinder 3, align the outer circumference of the cylinder with the slot 201 and insert it to connect with the rotating ring 2. When the motor 104 drives the separator cylinder 3 to rotate, the rotating ring 2 rotates within the bearing 105, increasing the stability of the separator cylinder 3 during rotation.

[0037] The filter disc 4 has a large number of equally spaced filter holes, and the inner diameter of the filter disc 4 is smaller than the inner diameter of the separation cylinder 3.

[0038] The upper part of the central column 301 is threadedly connected to the threaded cylinder 5, and a handwheel 501 is fixed on the outer periphery of the threaded cylinder 5. The bottom end of the threaded cylinder 5 abuts against the surface of the uppermost filter disc 4.

[0039] After all the filter discs 4 are installed, the threaded cylinder 5 is finally placed on the central column 301, and the threaded cylinder 5 is moved down by rotating the handwheel 501 until it is pressed against the filter discs 4 to prevent shaking during subsequent centrifugal oil filtration operations.

[0040] The specific working principle of this utility model is as follows: First, the oil-containing grease is placed inside the separation cylinder 3. Then, the filter discs 4 and sleeves 401 are fitted onto the outside of the central column 301, so that the upper and lower parts of the filter discs 4 form equal spaces. This process is repeated until all filter discs 4 are installed, preventing all oil residue from accumulating at the bottom of the separation cylinder 3. In this way, a certain amount of oil residue accumulates between every two filter discs 4. Finally, the threaded cylinder 5 is fitted onto the central column 301, and the threaded cylinder 5 is moved down by rotating the handwheel 501 until it is pressed against the filter discs 4. Then, the locking blocks 302 on the outer periphery of the separation cylinder 3 are engaged. The quasi-slot 201 is engaged to connect with the rotating ring 2. After a slight rotation, the positioning element is engaged in the limiting groove 3031. Finally, the can lid 101 is screwed closed. The motor 104 drives the limiting element 1061 to rotate. The limiting element 1061 is engaged in the limiting groove 3031, which in turn drives the cross-shaped frame 303 and the separation cylinder 3 to rotate. The upper part of the separation cylinder 3 is engaged with the rotating ring 2 to maintain stability during rotation, thereby achieving centrifugal oil filtration and separation of oil residue. After a certain period of time, a new separation cylinder 3 filled with oil for frying can be replaced.

[0041] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
