Description

Technical Field

[0001] The utility model relates to the technical field of lard production, in particular to a lard residue extrusion device for pigs. Background Art

[0002] Lard residue is obtained by boiling and refining the fat tissue in pork, separating various fatty acids (i.e., lard, animal fat) from the fat cell tissue. The solid hard mass remaining after extracting lard by boiling is lard residue, which contains fat cell tissue and a large amount of saturated fat that cannot be separated.

[0003] In the prior art, most lard residue separation devices use a rotating separation belt for separation. A separation tank is arranged below the separation belt, but the separation effect is not very ideal. After separation, a large amount of fine lard residue still enters the oil liquid, and the amount of lard residue separated each time is not too much, thus reducing the separation quality.

[0004] Therefore, it is particularly important to design a lard residue extrusion device for pigs to change the above technical defects and improve the overall practicability. Content of the Utility Model

[0026] A lard residue extrusion device for pigs, comprising a machine body 1. A feed inlet 2 is arranged at the top of the machine body 1 for feeding materials. An extrusion chamber 3 is arranged in the middle of the interior of the machine body 1 to accommodate structural components. Driving chambers 4 are arranged at the left and right ends inside the machine body 1 to accommodate driving components. Support rods 6 are arranged on the left and right sides of the front and rear sides at the uppermost end inside the extrusion chamber 3 on the inner wall for fixed connection of the structure. Main extrusion rollers 5 are mounted on the sides of the support rods 6 at the left and right ends away from the inner wall of the extrusion chamber 3 for extrusion and pressing. The main shafts of the centers of the front and rear sides of the main extrusion rollers 5 are each connected with a pulley 7. The left end of the left pulley 7 and the right end of the right pulley 7 are each connected with a driving belt 8 for transmitting driving power. The ends of the left and right driving belts 8 away from the pulleys 7 are connected with a first driving motor 9 for driving rotation. The lower end of the pulley 7 is connected with a first transmission belt 10 for transmitting the power of rotation. The lower end of the first transmission belt 10 is connected with a fine extrusion structure 11. Coarse screen meshes 12 are arranged on the left and right sides of the lower inner wall inside the extrusion chamber 3 for the first layer of filtration. A fine screen mesh 13 is arranged below the coarse screen mesh 12 for the second layer of screening. A discharge funnel 19 is arranged at the bottom of the fine screen mesh 13 for collecting and discharging. An electric telescopic rod 14 is arranged at the lower end inside the driving chamber 4 for driving telescoping. A push block 15 is arranged at the end of the electric telescopic rod 14 close to the extrusion chamber 3 for shoveling materials movably. Second driving motors 16 are arranged inside the front and rear sides of the push block 15 for driving rotation. The ends of the second driving motors 16 away from the push block 15 are each connected with a rolling belt 17 for transmitting the force of rolling. A rolling roller 18 is arranged at the end of the rolling belt 17 away from the second driving motor 16 for rolling;

[0027] The first drive motor 9 is arranged at the upper end inside the left and right drive bins 4, and the left and right drive belts 8 are respectively connected to the shaft ends on the front sides of the first drive motors 9 at the left and right ends, so that the drive device can be easily operated. The front and rear end central axes of the main squeezing rollers 5 are rotatably connected to the support rods 6 at the left and right ends, so that they can keep rotating in a fixed position. The fine squeezing structure 11 includes four groups of fine squeezing rollers 20, and two are arranged in a group laterally. The upper and lower groups of the left and right fine squeezing rollers 20 are connected by the second transmission belt 21. The fine squeezing rollers 20 in each lateral group rotate in opposite directions, so that further rolling can be performed. The side of the push block 15 away from the rolling roller 18 is connected to the output end of the electric telescopic rod 14 away from one end inside the drive bin 4, and the left and right electric telescopic rods 14 are respectively fixedly connected to the inside of the left and right drive bins 4. The output end of the electric telescopic rod 14 passes through the common through groove opened on the inner wall of the extrusion bin 3 and the extrusion bin 3, so that it can flexibly drive the extension. The second drive motor 16 is fixedly arranged inside the front and rear ends of the push block 15, and the shaft end of the second drive motor 16 is located outside the front and rear ends of the push block 15. The rolling belt 17 connects the shaft end of the second drive motor 16 and the central axis of the rolling roller 18, and the connection method is a transmission connection, so that the rolling roller 18 can be driven by the tiger to roll. The bottoms of the left and right push blocks 15 are both placed on the left and right ends of the top of the fine screen 13, and the connection method is a movable connection, so that the lard residue on the top of the coarse screen 12 can be flexibly pushed. The sieve hole of the coarse screen 12 is slightly coarser than the sieve hole of the fine screen 13, so that multiple filtering and screening can be performed, which solves the problem that the separation effect is not very ideal and the separation quality will be reduced.

[0028] The working process of the utility model is as follows: firstly, the lard residue extrusion device is placed on a plane, and then the lard residue is poured into the interior of the extrusion bin 3 from the feed port 2, and at the same time, the first drive motor 9 is started, and the transmission drive belt 8 drives the main extrusion rollers 5 at the left and right ends to rotate in opposite directions. At the same time, under the action of the first transmission belt 10 and the second transmission belt 21, the two groups of fine extrusion rollers 20 also start to perform secondary extrusion on the lard residue falling downward, and then the lard residue will fall downward into the top of the coarse screen 12, and then the electric telescopic rods 14 at the left and right ends will alternately telescope, thereby driving the electric telescopic rods 14 at the left and right ends to alternately telescope toward the center position, and at the same time, the second drive motor 16 is started to drive the rolling roller 18 to repeatedly roll the lard residue on the top of the coarse screen 12, so that the push block 15 is responsible for shoveling and turning the lard residue, and the rolling roller 18 is responsible for the optimal extrusion work, and finally the filtered oil will drip downward, pass through the filtration of the fine screen 13, and be discharged from the discharging funnel 19.
