Description

Technical Field

[0001] This utility model relates to the field of poultry and livestock slaughtering and processing, and in particular to a device for reusing overflow water from a wax pool. Background Technology

[0002] In the poultry and livestock slaughtering and processing industry, wax tanks are key equipment for removing feathers from poultry and livestock. Wax tanks typically use steam to heat water in a tank to a high temperature (approximately 80-90°C), melting the wax and keeping it liquid for the dehairing process. However, existing wax tank systems have the following problems during operation:

[0003] 1. Significant waste of heat energy: During the continuous heating process, the wax pool water tank needs to continuously discharge high-temperature overflow water (usually above 80℃) in order to maintain a stable water level. This high-temperature overflow water is directly discharged into the sewer, which not only causes a large amount of heat energy waste.

[0004] 2. High energy consumption: To meet production needs, the wax pool needs to be continuously replenished with cold water and heated to the working temperature. Since the replenished cold water (such as tap water or well water, the temperature is usually 10-20℃) is low, the steam pot needs to consume a lot of steam to heat it to the target temperature, resulting in low energy utilization. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a device for reusing overflow water from a wax pool.

[0006] The technical solution includes a tee fixedly installed at the overflow pipe opening of the water tank. The inlet of the tee is connected to the overflow pipe, one outlet is connected to a pipe, and the other outlet is equipped with a pressure relief valve.

[0007] The end of the pipe away from the overflow pipe is connected to the outer sleeve, which is fixed on the ground by several supports and is fitted over the outside of one section of the water tank inlet pipe;

[0008] A drain pipe is installed at the end of the outer sleeve away from the pipe.

[0009] Preferably, the pressure relief valve includes a mounting base detachably connected to the tee, a pressure cap is fixedly mounted on the mounting base, a central column is slidably mounted on the pressure cap, a plug is fixedly mounted at the lower end of the central column, a spring is provided between the plug and the pressure cap, and the spring is sleeved on the outside of the central column.

[0010] Preferably, the bracket includes a base plate with mounting holes, a support column is fixedly mounted in the middle of the base plate, a semi-circular lower fixing plate is fixedly mounted at the upper end of the support column, an upper fixing plate is detachably mounted on the lower fixing plate, and the upper fixing plate and the lower fixing plate are detachably connected by bolts.

[0011] Preferably, the outer wall of the water inlet pipe located inside the outer sleeve is provided with spiral fins.

[0012] Preferably, a valve is installed on the pipeline.

[0013] The beneficial effects of the technical solution provided by this utility model embodiment are as follows: This device recovers the heat energy of the high-temperature overflow water discharged from the wax pool through the nested structure of the outer sleeve and the water inlet pipe, and preheats the cold water in the water inlet pipe, avoiding the waste of heat energy caused by the direct discharge of high-temperature overflow water, making the originally idle heat energy effectively utilized, and significantly improving the energy utilization rate; after the preheated cold water enters the steam pot, it can reach the target temperature without consuming a large amount of steam, greatly shortening the heating time.

[0024] Example 1

[0025] See Figures 1 to 5 This utility model provides a device for reusing overflow water from a wax tank, including a tee 3 fixedly installed at the outlet of the overflow pipe 2 of the water tank 1. The inlet of the tee 3 is connected to the overflow pipe 2, one outlet is connected to the pipe 4, and the other outlet is equipped with a pressure relief valve 5.

[0026] The end of pipe 4 away from overflow pipe 2 is connected to outer sleeve 6. The outer sleeve 6 is fixed on the ground by several supports 7 and is sleeved on the outside of one section of water inlet pipe 20 of water tank 1.

[0027] A drain pipe 8 is installed at the end of the outer casing 6 that is away from the pipe 4.

[0028] When the wax tank is running, the hot water used for wax melting in water tank 1 is discharged from overflow pipe 2 due to excessive water level, and first enters the tee 3 fixed at the opening of overflow pipe 2:

[0029] Most of the overflow water above 80°C flows into the connected pipe 4 through one of the outlets of the tee 3, and is then transported to the outer casing 6 via the pipe 4.

[0030] Meanwhile, cold water such as tap water or well water is introduced into the inlet pipe 20 of water tank 1. When the cold water flows through the pipe section covered by the outer sleeve 6, it exchanges heat with the high-temperature overflow water inside the outer sleeve 6 through the pipe wall. After the cold water temperature rises by 20-30℃, it continues to be transported to the subsequent steaming pot.

[0031] The overflow water from the end of the outer jacket 6 away from the pipe 4 is discharged through the drain pipe 8;

[0032] If abnormal pressure occurs in the tee 3 and subsequent pipes 4 and outer sleeve 6, such as blockage leading to excessive pressure, water in the overflow pipe 2 will flow out from the pressure relief valve 5 to release excess pressure and ensure the safe operation of the device.

[0033] The pressure relief valve 5 includes a mounting base 9 that is detachably connected to the tee 3. A pressure cap 10 is fixedly mounted on the mounting base 9. A central column 11 is slidably mounted on the pressure cap 10. A plug 12 is fixedly mounted at the lower end of the central column 11. A spring 13 is mounted between the plug 12 and the pressure cap 10. The spring 13 is sleeved on the outside of the central column 11.

[0034] Spring 13 is in a pre-tightened state, and the plug 12 is pressed against the valve port of pressure relief valve 5 by the central column 11, ensuring that the overflow water can only flow to the outer sleeve 6 through the tee 3, and pressure relief valve 5 is in a closed state;

[0035] If the pressure in the outer sleeve 6 or pipe 4 exceeds the preload of the spring 13 due to blockage or obstruction of water flow, the upward thrust on the plug 12 is greater than the elastic force of the spring 13. The central column 11 slides upward along the pressure cap 10, the plug 12 leaves the valve port, the pressure relief valve 5 opens, and some overflow water is discharged through the pressure relief valve 5 to reduce the system pressure.

[0036] When the system pressure drops below the preload of spring 13, spring 13 pushes plug 12 back to the valve port, resealing it, and the pressure relief valve 5 closes, allowing the device to resume normal operation.

[0037] The bracket 7 includes a base plate 14 with mounting holes. A support column 15 is fixedly installed in the middle of the base plate 14. A semi-circular lower fixing plate 16 is fixedly installed at the upper end of the support column 15. An upper fixing plate 17 is detachably installed on the lower fixing plate 16. The upper fixing plate 17 and the lower fixing plate 16 are detachably connected by bolts.

[0038] The bracket 7 is fixed to the ground using expansion bolts or welding through the mounting holes on the base plate 14 to ensure that the bracket 7 is stable.

[0039] The outer sleeve 6 is placed in the semi-circular groove of the lower fixing plate 16. The curvature of the groove matches the outer diameter of the outer sleeve 6 to provide stable support.

[0040] The upper fixing plate 17 forms a complete circular hole with the lower fixing plate 16, and the two are locked together with bolts to achieve reliable fixation of the outer sleeve 6.

[0041] Spiral fins 18 are provided on the outer wall of the water inlet pipe 20 located inside the outer casing 6.

[0042] When the high-temperature overflow water flows from the tee 3 through the pipe 4 into the outer casing 6, it flows along the outer wall of the inlet pipe 20 in a spiral path under the guidance of the spiral fins 18, prolonging the water flow path and residence time.

[0043] At the same time, the cold water in the inlet pipe 20 comes into contact with the spiral fins 18, and the fins 18 efficiently transfer the heat of the overflowing water to the cold water, causing the cold water temperature to gradually rise.

[0044] The spiral fins 18 not only increase the heat transfer area, but also promote the formation of turbulent flow in the overflow, disrupting the boundary layer and further enhancing the heat exchange efficiency.

[0045] Valve 19 is installed on pipe 4.

[0046] The installation of valve 19 allows for partial maintenance without draining the entire system, reducing maintenance time and water waste;

[0047] For fins 18 or outer tubes 6 that require regular chemical cleaning, cleaning agent can be injected independently after valve 19 is closed to improve the cleaning effect.

[0048] When this utility model is in use, during the operation of the wax tank, the hot water used for wax melting in the water tank 1 is discharged from the overflow pipe 2 due to the excessively high water level, and first enters the tee 3 fixed at the pipe opening of the overflow pipe 2:

[0049] Most of the overflow water above 80°C flows into the connected pipe 4 through one of the outlets of the tee 3, and is then transported to the outer casing 6 via the pipe 4.

[0050] Meanwhile, cold water such as tap water or well water is introduced into the inlet pipe 20 of water tank 1. When the cold water flows through the pipe section covered by the outer sleeve 6, it exchanges heat with the high-temperature overflow water inside the outer sleeve 6 through the pipe wall. After the cold water temperature rises by 20-30℃, it continues to be transported to the subsequent steaming pot.

[0051] The overflow water from the end of the outer jacket 6 away from the pipe 4 is discharged through the drain pipe 8;

[0052] If abnormal pressure occurs in the tee 3 and subsequent pipes 4 and outer sleeve 6, such as blockage leading to excessive pressure, water in the overflow pipe 2 will flow out from the pressure relief valve 5 to release excess pressure and ensure the safe operation of the device.

[0053] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
