Abstract
Description
Technical Field
[0001] This utility model relates to sterilization equipment for the carcasses of diseased and dead animals, and more particularly to a high-pressure steam sterilizer for diseased and dead animals. Background Technology
[0002] Unnatural deaths are common in livestock and poultry farming, especially those caused by infectious pathogens. The carcasses of these animals, carrying pathogens, can still serve as a source of infection, spreading the disease. Therefore, to prevent carcasses from becoming a source of infection, appropriate treatment is generally implemented according to disease prevention requirements, such as landfilling, incineration, or harmless treatment followed by use as feed. While landfilling and incineration are quick and effective methods for disposing of carcasses, they also result in waste. Therefore, harmless treatment followed by use as feed is a more suitable method, maximizing the utilization value of animal carcasses and reducing economic losses for farmers. The main purpose of harmless treatment is to inactivate the pathogens carried by the animal carcasses. Traditional high-pressure steam sterilization uses conventional high-pressure containers to sterilize animal carcasses. During high-pressure steam sterilization, a large amount of oil and water is generated, which adheres to the inner wall of the high-pressure container, making cleaning difficult. Utility Model Content
[0003] The technical problem to be solved by this utility model is that existing high-pressure steam sterilization containers produce oil stains that adhere to the inner wall of the container during the high-pressure steam sterilization of animal carcasses, which is time-consuming to clean. In view of the above-mentioned defects of the prior art, a high-pressure steam sterilizer for dead animals is provided.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is to construct a high-pressure steam sterilizer for dead animals, including a box body and an oil-water collection tray. The oil-water collection tray is detachably installed at the bottom of the box body. The top of the box body is open and sealed by a cover. The cover is located inside the box body and has several spray pipes that are inclined towards each side wall of the box body near the edge of the cover. The spray pipes are connected to a steam injection pipe installed at the top of the cover. The steam injection pipe is connected to an external steam device through a steam pipe and valve A. In use, high-temperature steam is blown onto the inner side wall of the box body through the spray pipes to prevent oil stains generated during the high-temperature and high-pressure sterilization process from sticking to the inner side wall of the box body.
[0005] Preferably, an annular steam pipe is provided on the inner side of the cover, the lower side of the annular steam pipe is connected to each nozzle, and the upper side is connected to the steam injection pipe.
[0006] Preferably, a drainage plate is provided on the inner side wall of the box. The drainage plate is inclined downward and set on the upper side to form an inclined drainage surface. The lower end of the drainage plate extends to the top of the drawer so that the oil and water adhering to the side wall of the box can flow into the oil and water collection drawer along the end of the drainage surface under the action of high temperature and high pressure steam.
[0007] Preferably, the end of the drain plate is blade-shaped, which can reduce residual oil stains at the end of the drain plate.
[0008] Preferably, the inner side of the box is also provided with a grate for placing animal carcasses, and the grate is located above the drainage plate.
[0009] Preferably, the bottom side of the box body is provided with an installation port for disassembling / installing the oil and water collection tray, and two fixing ears are provided on the outer side wall of the box body on both sides of the installation port. The oil and water collection tray is fixedly connected to the fixing ears by fixing screws.
[0010] Preferably, an oil-absorbing paper is provided on the outer side of the side wall that contacts the inner side wall of the oil-water collection drawer to prevent oil and water on the side wall of the box below the diversion plate from contaminating the outer wall of the oil-water collection drawer.
[0011] Preferably, a hot water injection pipe is also provided on the upper side of the cover. The hot water injection pipe is connected to each spray pipe and is connected to the hot water outlet of the external boiler through a water pipe and valve B.
[0012] Preferably, the nozzle is connected to the steam injection pipe and the hot water injection pipe through an annular steam pipe disposed within the cover.
[0013] The beneficial effects of this utility model are as follows:
[0014] The lower side of the cover of this utility model is provided with several spray pipes that are inclined toward each side wall of the box. The spray pipes are connected to the external steam equipment through the steam injection pipe provided on the upper side of the cover and valve A. In this way, when in use, the external high temperature and high pressure steam is injected into the box through the steam injection pipe and the spray pipes, forming a high temperature and high pressure environment inside the box. Moreover, the steam sprayed on the side wall of the box can remove the oil and other stains adhering to the side wall of the box.
[0015] This utility model has a diversion plate on the inner side wall of the box. The diversion plate is inclined downward and set on the upper side to form an inclined diversion surface. The lower end of the diversion plate extends to the top of the drawer so that the oil and water adhering to the side wall of the box can flow into the oil and water collection drawer along the end of the diversion surface under the action of high temperature and high pressure steam.
[0016] The end of the drainage plate of this utility model is blade-shaped, which makes it less likely for oil and water droplets left along the inclined drainage plate to remain at the end of the drainage plate due to the small contact area with the end of the drainage plate. In other words, oil or water droplets are more likely to drip off from the end of the drainage plate. Attached Figure Description

[0023] like Figure 1-5 As shown in the figure, this embodiment specifically discloses a high-pressure steam sterilizer for dead animals, including a box body 1 and an oil and water collection tray 2. The box body 1 is a square box with an open top, and the open top is sealed by a cover 3. The cover 3 is a door-shaped structure or the cover 3 is fixed to the open top by bolts.
[0024] The oil-water collection tray 2 is detachably located at the bottom of the housing 1. Specifically, one side of the bottom of the housing 1 has an installation port for disassembling and installing the oil-water collection tray. Two fixing ears are provided on the outer side walls of the housing on both sides of the installation port. The oil-water collection tray 2 is fixedly connected to the fixing ears by fixing screws. This allows the oil-water collection tray 2 to be easily disassembled and installed.
[0025] In some embodiments, when the cover 3 is located at the opening, a plurality of nozzles 31 are provided on the lower side of the cover 3 near the edge of the cover 3. The nozzles 31 on each side of the cover 3 are inclined toward the inner wall of the box 1 on the side where the side is located. In this way, when high-pressure airflow or high-pressure waterflow is ejected from the nozzle 31, the high-pressure airflow or high-pressure waterflow can be sprayed at an inclined angle onto the inner wall of the box 1, and cause part of the high-pressure airflow or part of the high-pressure waterflow to continue to flow downward along the side wall of the box 1.
[0026] Furthermore, the nozzle 31 is connected to the steam injection pipe 32 located at the top of the cover 3. Specifically, an annular steam pipe 34 is also provided inside the cover. This annular steam pipe 34 is a closed rectangular pipe, meaning it is located along the edge of the cover 3. The nozzle 31 is directly connected to the annular steam pipe 34, and the steam injection pipe 32 is directly connected to the annular steam pipe 34, thus indirectly connecting the nozzle 31 and the steam injection pipe 32. The steam injection pipe 32 is connected to an external steam device via a steam pipe and valve A (the steam pipe, valve A, and external steam device are not shown in the attached figure). When autoclaving the animal carcass inside the chamber 1, high-temperature steam is injected into the chamber 1 through the nozzle 31, creating a high-temperature and high-pressure environment inside the chamber 1. The high-temperature steam is directly sprayed onto the inner wall of the chamber 1 through the end of the nozzle 31. This high-temperature steam sprayed onto the inner wall of the chamber 1 washes away the oil stains adhering to the inner wall of the chamber 1 generated during the high-temperature and high-pressure sterilization process, keeping the inner wall of the chamber 1 clean.
[0027] It should be noted that, in order to reduce the manufacturing cost of the cap 1, the cap 1 can be composed of two parts, upper and lower. In this way, during manufacturing, it is only necessary to open the corresponding annular grooves at the corresponding positions on the opposite sides of the two parts. When the two parts are combined together, an annular steam pipe 34 can be formed. The lower side of the annular steam pipe 34 is connected to each nozzle 31, and the upper side is connected to the steam injection pipe 32.
[0028] To prevent the oil or water washed away by the steam sprayed on the inner wall of the box 1 from flowing into the bottom of the box 1 along the inner wall of the box 1, a diversion plate 11 is provided on the inner wall of the box 1. The diversion plate 11 is located on the upper side of the oil and water collection drawer 2 and is inclined downward to form an inclined diversion surface on the upper side of the diversion plate 11. The lower end of the diversion plate 11 extends to the upper part of the middle of the drawer 2 so that the oil and water adhering to the side wall of the box 1 can flow into the oil and water collection drawer 2 along the end of the diversion surface under the action of high temperature and high pressure steam.
[0029] Furthermore, to avoid a large amount of water or oil droplets remaining at the end of the drainage plate 11, the end of the drainage plate 11 is blade-shaped. The blade-shaped end can reduce the residual oil stains at the end of the drainage plate, making it easier for oil or water droplets to fall off.
[0030] In some embodiments, a grate 12 for placing animal carcasses is also provided inside the box 1, and the grate 12 is located above the drainage plate 11.
[0031] Since a small amount of oil or water stains may remain on the inner wall of the box 1 at the bottom of the diversion plate 11, they may flow down along the inner wall of the box 1 under high temperature conditions. Therefore, in order to prevent oil or water stains from flowing directly into the gap between the oil and water collection tray 2 and the inner wall of the box 1, an oil-absorbing paper (not shown in the attached figure) is provided on the outer side of the side wall of the oil and water collection tray 2 that contacts the inner wall of the box 1, so as to prevent oil and water on the side wall of the box 1 below the diversion plate 11 from contaminating the outer wall of the oil and water collection tray 2.
[0032] To clean the oil and stains still adhering to the inner wall of the chamber 1 after sterilization, a hot water injection pipe 33 is installed on the upper side of the cover 3. The hot water injection pipe 33 is connected to each spray pipe 31 through a ring-shaped steam pipe 34, and is also connected to the hot water outlet of an external boiler through a water pipe and valve B. In this way, after sterilization, the inner wall of the chamber 1 can still be rinsed by spraying high-temperature water into the chamber 1. Of course, before spraying water, valve A connected to the steam injection pipe 32 should be closed, and valve B connected to the hot water injection pipe 33 should be opened to inject hot water into the chamber 1 to rinse the inner wall of the chamber 1. The rinsing hot water flows along the guide plate 11 into the oil and water collection tray 2.
[0033] Finally, it should be noted that this utility model also has a support frame, which is set at the bottom of the box to provide support for the box.
[0034] Since the sterilization process takes place under high temperature and high pressure, a pressure gauge 35 is installed on the cap 3 to ensure the safety of the sterilizer. The pressure gauge 35 is connected to the inside of the chamber through a pipe.
[0035] Finally, it should be noted that sealing gaskets are installed between the cover and the opening of the box, and between the oil and water collection drawer and the mounting port on the side of the box, to prevent air leakage at the connection points and thus prevent pressure loss.
[0036] It should be understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
