Description

Technical Field

[0001] The invention relates to a fully automatic circulating canal scalding pool for pig slaughtering, belonging to the field of livestock slaughtering. Background Art

[0002] With the rapid development of today's society, livestock are becoming more and more practical, especially pigs. However, now basically large-scale pig farms or slaughtering industries are automated industries. Almost all pigs will be automatically depilated when they are slaughtered, and the canal scalding pool is the key device for slaughtering and depilating pigs. However, existing similar products are mainly right-angle U-shaped scalding pools or linear scalding pools, which have many problems. For example, the radius of the corner wheel is small, and the pig body is prone to loosening and cross collision at the turning point due to inertia. At the same time, eddy currents are prone to occur at right-angle turns. The superposition of several factors can easily cause the hook to be unhooked; the water circulation is completely dependent on the water pump to pump water from the front end to the back end, the circulation speed is slow, the heating efficiency is low, and other problems. These problems directly increase the depilation time significantly, and will also affect the final depilation effect, which is very impractical. Summary of the invention

[0003] According to the problem described in the background, the problem to be solved by the present invention is: to provide a fully automatic circulating canal scalding pool for pig slaughtering, by connecting the front and back of the scalding pool to make the scalding pool a complete circulating structure, and at the same time, the trough body between the straight sections from the inlet end to the outlet end of the scalding pool adopts an arc-shaped transition connection to make the water flow run more smoothly and reduce cross collision; add a water pump circulation pipeline, and the water pump suction port is installed obliquely in the opposite direction of the pig inlet, so that the pumping and drainage directions are consistent with the water flow direction, so as to realize automatic circulation of the scalding pool water flow, improve the water flow speed and convection heating effect, shorten the heating time, and at the same time, the faster reverse water flow makes it easy to maintain the backward pulling force of the pig body on the hook to avoid unhooking; use a new double-hinged chain with side guide and remove two corner wheels to make the operation smoother; there are also pig pressing devices, scalding pool shields and other places to make the whole process smoother, higher heat transfer, higher efficiency and better yield.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a fully automatic circulating canal scalding pool for pig slaughtering is provided, comprising a scalding pool body, a water pump circulation pipeline, an inlet descending track, an outlet lifting track, a double-hinged chain, a supporting crossbeam frame, a pig pressing device, a hook chain, a scalding pool shield and a drainage pipeline. Drainage pipelines are provided at the inlet and outlet of the scalding pool body to discharge excess water. A water pump circulation pipeline is installed between the inlet and outlet of the scalding pool body, and the water pump circulation pipeline spans the scalding pool path of the scalding pool body, so that the water flow can be added more evenly without generating excessive fluctuations. The inlet descending track and the outlet lifting track are The paths are respectively installed at the entrance and exit of the scalding pool body, while the entrance descending track and the exit lifting track are connected together along the outermost periphery of the scalding pool path of the scalding pool body, the double-hinged chain is located inside the entrance descending track and the exit lifting track, the supporting crossbeam is installed on the scalding pool body and spans the scalding pool path through which the pig carcasses of the scalding pool body pass, the pig pressing device is installed below the supporting crossbeam and at the same position as the supporting crossbeam on the scalding pool body, one end of the hook chain is connected to the double-hinged chain and the other end is hung on the pig carcass, the scalding pool shield is installed above the supporting crossbeam and covers part of the scalding pool path of the scalding pool body to provide heat preservation.

[0005] The scalding pool body comprises a steel tube frame, an outer wall, an inner wall, a thermal insulation layer, a steam heating device and a water pump pipeline support frame. The outer frame of the scalding pool body formed by the steel tube frame is a semicircular connecting structure at one end. The inner wall and the outer wall are arranged on the inner and outer sides of the steel tube frame, so that the entire scalding pool becomes a whole. A thermal insulation layer is arranged between the inner wall and the outer wall to prevent the hot water from cooling down quickly. The steam heating device is located at the bottom of the steel tube frame and between the inner wall and the outer wall, which can also prevent the hot water from cooling down and enhance the thermal efficiency. The steam nozzle is discharged downward into the bottom of the scalding pool to avoid direct contact between the steam and the pig carcass. The water pump pipeline support frame is arranged in the middle position between the entrance and the exit of the scalding pool body and spans the steel tube frame.

[0006] The water pump circulation pipeline includes a water pump inlet, a water pump, a water pipe and a water outlet nozzle. The water pipe is S-shaped and fits the hot spring body better. A water pump inlet is installed at one end, and multiple groups of water outlet nozzles are vertically installed at the other end to make the water output more uniform and will not cause large fluctuations. A water pump is also provided at the bend near the water pump inlet of the water pipe to provide water diversion.

[0007] The entrance descending track and the exit lifting track both include a track beam and a hook. A double-hinged chain runs inside the track beam. A hook is installed under the double-hinged chain to cooperate with the hook chain to hang the pig carcass.

[0008] The supporting crossbeam frame includes a fixing plate, a track fixing plate, a crossbeam and a pig pressing device hanging rod. A fixing plate is installed at each of the left and right ends of the crossbeam for fixing to the scalding pool body. A track fixing plate is installed at the upper end of the crossbeam near the edge for fixing the track. A pig pressing device hanging rod is installed at the lower end of the crossbeam for installing the pig pressing device. The crossbeam is a U-shaped square tube structure, which is more solid and has stronger supporting force.

[0009] The pig pressing device comprises a pig pressing grille and a pig pressing grille hanger. A plurality of pig pressing grille hangers are installed on the pig pressing grille and are used in conjunction with the pig pressing device hanger. The pig pressing grille is a round tube grille structure, and the round tube fits the surface of the live pig carcass more closely.

[0010] The hook chain comprises a hook, a chain, a locking rod and a locking chain. The lower end of the hook is connected to the chain, the lower end of the chain is covered with a locking rod, and the lower end of the locking rod extends out and is connected to the locking chain, which can better tie up the legs of the pig carcass and prevent it from falling easily.

[0011] The water pump circulation pipeline is specifically installed on the water pump pipeline support frame; the inlet descending track and the outlet lifting track are specifically installed on the track fixing plate on the supporting crossbeam frame; the supporting crossbeam frame is specifically installed on the steel pipe frame of the scalding pool body through the fixing plate; the pig crushing device is specifically installed on the pig crushing device hanger of the supporting crossbeam frame through the pig crushing grid hanger; the hook chain is specifically installed on the hook.

[0012] Preferably, the scalding pool body is a continuous groove-shaped structure connected end to end, and the bottom structure of the scalding pool body is a shallow V-shaped structure to facilitate drainage.

[0013] Preferably, the structure of the scalding pool body can be deformed into a rounded rectangle with protruding corners of the inlet and outlet and a rounded rectangle with a protruding inlet. Both rounded rectangles have no central space. The remaining components are adjusted according to the structure of the scalding pool body. The outer dimensions can be compressed to adapt to different process requirements, while further improving the overall thermal insulation effect.

[0014] Working principle: The pig carcass comes from the previous step and enters the scalding tank through the entrance descending track. The water pump circulation pipeline starts to generate water flow for heating. Because the pumping and drainage directions of the water pump are consistent with the water flow direction, the automatic circulation of the scalding tank water flow can be realized, the water flow speed and convection heating effect can be increased, and it is also easy to maintain the backward pulling force of the pig carcass on the hook. Then the pig carcass enters the curve area and runs stably under the action of the pig pressing device. Because of the presence of the scalding tank shield, insulation layer and steam heating device, the water temperature can be kept stable. Finally, it is lifted out through the outlet lifting track to enter the next step.

[0015] The beneficial effects of the present invention are:

[0016] 1. The scalding pool body adopts a continuous trough structure connected from end to end. The semicircular turning is smoother and the water flow is smoother, which can reduce the cross collision caused by the corner and avoid the occurrence of unhooking. The bottom of the scalding pool is a shallow V-shaped structure, which is convenient for drainage and not easy to cause blockage. There is a steam heating device on the inner wall of the scalding pool, and the steam nozzle is discharged downward into the bottom of the scalding pool to prevent the steam from directly contacting the pig carcass.

[0017] 2. The use of hot pool cover, insulation layer and steam heating device can keep the water temperature stable, greatly improving the efficiency and hair removal effect.

[0018] 3. The hanging conveyor track has the same arc transition as the scalding tank body, which makes the pig carcass run more smoothly in the scalding tank, avoids the cross collision phenomenon when the pig carcass turns at right angles, and improves the heating uniformity. The conveying chain of the hanging track is a double-hinged chain with side guides, which makes the chain run more smoothly in the track and makes the heat efficiency evenly transmitted.

[0019] 4. A water pump circulation pipeline is installed in the connecting section of the trough from the outlet to the inlet of the scalding pool. The water pump suction port is installed obliquely in the opposite direction of the pig inlet, so that the water flow direction is consistent with the water circulation direction in the scalding pool, which increases the water flow speed and convection heating effect and shortens the heating time. At the same time, the faster reverse water flow makes it easy to maintain the backward pulling force of the pig body on the hook to avoid unhooking.

[0020] 5. The drain outlet of the scalding pool pipeline is symmetrically installed at the outlet end of the connecting section. The water nozzles on both sides are obliquely facing the middle of the scalding pool to generate an overall forward impact water flow. The overall water flow direction is opposite to the conveying direction of the hanging track, which makes it easier to discharge the water and avoid blockage.

[0021] 6. The pig pressing device makes the pig carcass more stable during operation, avoids ups and downs, and makes the water flow evenly through every part of the pig carcass, with higher thermal efficiency and better effect.

[0022] 7. The structure of the hot pool body includes two types of rounded rectangles: a rounded rectangle with protruding corners at the inlet and outlet and a rounded rectangle with protruding inlet. Both of these rounded rectangles have no central space, which compresses the outer dimensions, adapts to different process requirements, and further improves the overall thermal insulation effect.

[0023] 8. The connection between the front and rear ends of the entire device enables the water flow in the scalding pool to circulate as a whole. The faster water flow rate is conducive to improving the uniformity of water temperature and the heating efficiency of pig carcasses, shortening the heating time and improving the freshness of meat.

The water pump pipeline support frame 106 is arranged in the middle position between the inlet and the outlet of the scalding pool body 1 and spans the steel tube frame 101. The rounded rectangular structure with a protruding inlet can compress the outer size to adapt to different process requirements, while further improving the overall thermal insulation effect.

[0059] The water pump circulation pipeline 2 includes a water pump water inlet 201, a water pump 202, a water pipe 203 and a water outlet nozzle 204. The water pipe 203 is S-shaped and fits the scalding pool body 1 better. A water pump water inlet 201 is installed at one end, and multiple groups of water outlet nozzles 204 are vertically installed at the other end to make the water output more uniform and will not cause large fluctuations. A water pump 202 is also provided at the bend near the water pump water inlet 201 of the water pipe 203 to provide water diversion.

[0060] The entrance descending track 3 and the exit lifting track 4 both include a track beam 301 and a hook 302 . A double-hinged chain bar 5 runs inside the track beam 301 . A hook 302 is installed under the double-hinged chain bar 5 to cooperate with a hook chain 8 to hang the pig carcass 10 .

[0061] The supporting crossbeam frame 6 comprises a fixing plate 601, a track fixing plate 602, a crossbeam 603 and a pig pressing device hanging rod 604. The left and right ends of the crossbeam 603 are respectively installed with a fixing plate 601 for fixing on the scalding pool body 1. The upper end of the crossbeam 603 is installed with a track fixing plate 602 near the edge for fixing the track. The lower end of the crossbeam 603 is installed with a pig pressing device hanging rod 604 for installing the pig pressing device 7. The crossbeam 603 is a U-shaped square tube structure, which is more solid and has stronger supporting force.

[0062] The pig pressing device 7 includes a pig pressing grid 701 and a pig pressing grid hanger 702. A plurality of pig pressing grid hangers 702 are installed on the pig pressing grid 701 and are used in conjunction with the pig pressing device hanger 604. The pig pressing grid 701 is a round tube grid structure, and the round tube fits the surface of the live pig carcass 10 more closely.

[0063] The hook chain 8 includes a hook 801, a chain 802, a locking rod 803 and a locking chain 804. The lower end of the hook 801 is connected to the chain 802, and the lower end of the chain 802 is covered with a locking rod 803. The lower end of the locking rod 803 extends out and is connected to the locking chain 804, which can better tie the legs of the pig carcass 10 and prevent it from falling easily.

[0064] The water pump circulation pipeline 2 is specifically installed on the water pump pipeline support frame 106; the inlet descending track 3 and the outlet lifting track 4 are specifically installed on the track fixing plate 602 on the supporting beam frame 6; the supporting beam frame 6 is specifically installed on the steel pipe frame 101 of the scalding pool body 1 through the fixing plate 601; the pig pressing device 7 is specifically installed on the pig pressing device hanging rod 604 of the supporting beam frame 6 through the pig pressing grid hanger 702; the hook chain 8 is specifically installed on the hook 302.

[0065] The scalding pool body 1 is a continuous groove-shaped structure connected end to end, and the bottom structure of the scalding pool body 1 is a shallow V-shaped structure for easy drainage.

[0066] The pig carcass 10 comes from the previous step and enters the scalding tank body 1 through the entrance descending track 3. The water pump circulation pipeline 2 starts to generate water flow for heating. Because the pumping and drainage directions of the water pump are consistent with the water flow direction, the automatic circulation of the scalding tank water flow can be realized, the water flow speed and the convection heating effect can be improved, and it is also easy to maintain the backward pulling force of the pig carcass 10 on the hook. Then the pig carcass 10 enters the curve area and runs stably under the action of the pig pressing device 7. Because of the presence of the scalding tank shield 9, the insulation layer 104 and the steam heating device 105, the water temperature can be kept stable. Finally, it is lifted out through the outlet lifting track 4 to enter the next step.
