Description

Technical Field

[0001] The invention belongs to the technical field of environmentally friendly treatment equipment for biological waste, and more specifically is an environmentally friendly treatment device for medical DPF pig xenogeneic organ biological waste. Background Art

[0002] Environmental protection equipment for biological waste treatment is used to safely and effectively treat various types of biological waste to achieve the purpose of harmlessness, reduction and resource utilization. These equipment use a variety of treatment technologies for different types of biological waste to meet environmental protection and biosafety requirements. In the research and use of medical DPF pigs, biological waste carrying humanized genes will be produced. When these wastes are treated using environmental protection treatment equipment, they need to be converted into inorganic substances such as carbon dioxide, water and ash through high-temperature combustion. High-temperature environment can effectively kill various pathogens in biological waste, and make proteins and nucleic acids lose their biological activity, avoid possible ecological risks and health risks, and achieve harmless treatment. It is suitable for the treatment of infectious biological waste, has high treatment efficiency, and can quickly reduce the volume of waste. However, pungent and harmful gases may be produced during the incineration process, so it is necessary to be equipped with advanced exhaust gas purification systems to ensure that emissions meet environmental protection standards. In particular, biological organs contain a certain amount of protein, and elements such as sulfur and nitrogen in the protein will be converted into sulfur dioxide (SO2) and nitrogen oxides (NO X ) and other acidic gases, which not only have a pungent smell, but also cause pollution when discharged into the atmosphere, so a corresponding incineration tail gas treatment system must be equipped. However, the purchase of professional incineration equipment and the construction of a supporting exhaust gas treatment system also require the payment of energy costs and staff wages required for operation; moreover, in order to ensure that the incineration process meets environmental protection standards, it is necessary to continuously invest in equipment maintenance and upgrading, which undoubtedly increases the treatment cost.

[0004] In order to overcome the defects of the prior art, those skilled in the art provide the following technical solutions: a medical DPF pig xenogeneic organ biological waste environmental treatment device, comprising a crushing device for crushing biological tissue, a first inactivation device for high temperature and high pressure inactivation, and a second inactivation device for biological inactivation, the crushing device, the first inactivation device, and the second inactivation device are connected in sequence, the first inactivation device is used for high temperature and high pressure inactivation of the crushed biological tissue at a temperature of 120°C for not less than 2 hours, and the second inactivation device is filled with a protein and nucleic acid inactivation liquid; the crushing device comprises a spiral shaft and a pressure-bearing pipe for coaxially installing the spiral shaft, one end of the pressure-bearing pipe is provided with a material receiving funnel, and the biological tissue entering the pressure-bearing pipe through the material receiving funnel is squeezed by the spiral shaft and output forward to the first inactivation device.

[0005] Furthermore, a closing cover is axially and elastically installed at the outlet end of the pressure tube, and the closing cover includes a plug-in tube and a sealing plate. The plug-in tube is axially and slidably inserted into the outlet end of the pressure tube, and the sealing plate is elastically connected by a plurality of first springs. The first springs make the closing plate always close to the outlet end to close it. When the crushed biological tissue in the pressure tube accumulates to a maximum, the closing cover is pushed open to allow the biological tissue to flow out.

[0006] Furthermore, a discharge hole is provided on the bottom side wall at the outlet end of the pressure-bearing tube, and when the plug-in tube moves axially toward the outside of the pressure-bearing tube, the discharge hole is exposed to realize the discharge of biological tissue.

[0008] Furthermore, a tearing device for tearing biological tissue is also provided on the crushing device, and the tearing device includes two slide plates arranged opposite to each other on the left and right, and the two slide plates are installed for reverse sliding in the vertical direction. A claw rod is fixed perpendicularly to the opposite side of each slide plate, and the claw rods are arranged in the form of a rectangular array on the surface of the slide plate, and at the initial moment, the grab bars on the left and right sides are staggered with each other; the claw rods on each side are axially slidably fitted into a vertical plate, and the vertical plate is vertically slidably installed in the casing, and a baffle is respectively fixed on the front and rear sides of the two vertical plates, and the side surfaces of the vertical plates are slidably fitted with the baffle so that the vertical plates and the baffles form a rectangular tearing cavity; at the initial moment, the free ends of the claw rods on both sides are respectively located in the sockets on the corresponding vertical plates, and the two slide plates are moved according to the following path by a driving component: first, they are translated toward each other so that their respective claw rods extend out of the sockets and can penetrate into the biological tissue in the tearing cavity, and then the two slide plates move away from each other in the vertical direction to tear the biological tissue apart.

[0009] Furthermore, one end of a gate plate is hinged on the side of one of the vertical plates facing the tearing cavity, and a conductive and magnetic guide block is embedded in the other end of the gate plate, and the gate plate is made of non-magnetic material; a conductive strip that can vertically slide with the guide block is vertically fixed and embedded on the side of the other vertical plate facing the tearing cavity, and an electromagnet and a permanent magnet are installed behind the conductive strip. The permanent magnet can attract the gate plate in a vertically suspended state upward to make the guide block contact with the conductive strip. After the guide block contacts the conductive strip, the electromagnet is energized to firmly adsorb the guide block on the conductive strip.

[0010] Furthermore, one side of the guide block has a sliding column, which is horizontally slidably installed in the end face of the gate plate and is connected to a second spring in the end face of the gate plate, and when the guide block contacts the conductive strip, the second spring must be in a compressed state; the sliding column and the guide block are both horizontally arranged columnar structures, the two are integrally formed, and are horizontally slidably located in the center of the end face of the gate plate.

[0011] Furthermore, a drive shaft is fixed perpendicularly to the side surfaces of the two slides opposite to each other, and the drive shaft is vertically slidably installed in a vertical sliding hole in the casing. The length of the vertical sliding hole allows the claw rods on the left and right sides to move from an initially crossed position to a position where they are completely separated from each other.

[0012] Furthermore, the cross section of the claw rod is a square, and one of the diagonals of the cross section is in a vertical direction; the free end of the claw rod is a pointed end.

The top end of the connecting arm is fixed to the bottom of the sliding plate facing it, and at the initial moment, the piston plate is located below the vertical bar hole.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: the medical DPF pig xenogeneic organ biological waste environmental treatment device of the present invention first crushes the waste gas biological organ tissue, and then puts it into the first inactivation device of high temperature and high pressure for physical inactivation, and then sends it to the second inactivation device for chemical inactivation, so that the tissue protein and nucleic acid are denatured and decomposed. The three-level treatment method ensures that the medical DPF pig xenogeneic organ biological waste is fully and environmentally treated.

[0015] Moreover, some of the treated biological wastes in the present invention can be converted into organic fertilizers for agricultural production, or useful components can be extracted for industrial raw materials, etc. However, traditional incineration directly turns these potential resources into ashes, resulting in a huge waste of resources.

[0016] Other functions and features of the present invention will be specifically introduced in the subsequent embodiments to provide a full understanding of the concept of the present invention and thus to be specifically applied to production practice. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] Based on the several drawings in the embodiments of the present invention and referring to the following text description, a relatively clear and complete introduction of the technical scheme in the embodiments of the present invention can be made. However, it should be understood that the embodiments mentioned in this article are only one or several specific methods of the present invention, and not all implementation structures or method steps.

[0020] like Figure 1As shown, one of the specific embodiments of the present invention introduces in detail a medical DPF pig xenogeneic organ biological waste environmental treatment device, the main structure of which includes a crushing device 1 for crushing biological tissues, a first inactivation device 2 for high temperature and high pressure inactivation, and a second inactivation device 3 for biological inactivation. During installation, the crushing device 1, the first inactivation device 2, and the second inactivation device 3 are connected in sequence, and the waste passes through in sequence. Specifically, the first inactivation device 2 in this embodiment is used for crushed biological tissues, such as some broken bones and meat, at a temperature of 120°C, for high temperature and high pressure inactivation for not less than 2 hours, so that pathogens are killed and most of the proteins and nucleic acids lose their biological activity. In addition, the second inactivation device 3 is filled with an inactivation liquid for proteins and nucleic acids, which can be made of chemical substances, such as formalin for inactivating proteins and strong acid for inactivating DNA. In specific practice, a protein and nucleic acid inactivation liquid prepared with concentrated hydrochloric acid and formalin can be used. As Figure 2 As shown, the crushing device 1 includes a spiral shaft 102 and a pressure-bearing pipe for coaxially mounting the spiral shaft 102. The pressure-bearing pipe can withstand a great extrusion force. A receiving funnel 101 is provided at one end of the pressure-bearing pipe. The biological tissue entering the pressure-bearing pipe through the receiving funnel 101 is squeezed by the spiral shaft 102, and then crushed or even pulverized. These broken bones and meat are output forward to the first inactivation device 2 for high-temperature and high-pressure inactivation treatment. In actual production, an isolation cover 25 needs to be connected to the receiving funnel 101 so that the untreated organisms have no chance to contact the outside world; in addition, a discharge pipe 26 needs to be connected to the first inactivation device 2 to transport the broken bones and meat to the second inactivation device 3 for further inactivation, and a discharge port for discharging the treated residue is provided at the bottom of the second inactivation device 3.

[0021] Continue reading Figure 2 The outlet end of the pressure-bearing pipe is axially elastically and telescopically equipped with a closing cover, which includes an insert tube 103 and a closing plate 104. The insert tube 103 is axially slidably inserted into the outlet end of the pressure-bearing pipe, and can be specifically axially slidably installed on the inner wall of the pressure-bearing pipe, and the closing plate is elastically connected by a plurality of first springs 105. These first springs 105 make the closing plate always close to the outlet end, thereby closing the pressure-bearing pipe and improving the squeezing and crushing force of the spiral shaft 102 on the biological tissue during transportation. In specific operation, when the crushed biological tissue in the pressure-bearing pipe accumulates to a maximum, the squeezing pressure on the biological tissue has reached a set high-pressure range, and a relatively sufficient squeezing and crushing effect is obtained, thereby pushing the closing cover open to allow the broken bones and flesh of these biological tissues to flow out of the pressure-bearing pipe.

[0022] like Figure 2As shown, during the specific manufacturing process, a discharge hole 106 is provided on the bottom side wall at the outlet end of the pressure-bearing tube. When the plug-in tube 103 moves axially toward the outside of the pressure-bearing tube, the discharge hole 106 originally covered by the plug-in tube 103 is gradually exposed, thereby achieving the purpose of automatically discharging the broken bones and flesh of biological tissue from the discharge hole 106. In order to better achieve elastic expansion and contraction, so that the biological waste tissue can be fully squeezed and crushed, the first spring 105 mentioned above is arranged in a plurality of annular arrays around the outer side of the plug-in tube 103, and the axial direction of the first spring 105 is parallel to the axial direction of the pressure-bearing tube, and the discharge hole 106 and the first spring 105 are staggered to avoid affecting the discharge of the broken bones and flesh.

[0023] For some large organ tissues, or the environmentally friendly treatment of the whole DPF pig, it may be impossible for them to enter the crushing device 1 normally. For example, because of the large size, the whole cannot smoothly enter the above-mentioned pressure pipe. In order to solve this problem, the present embodiment is also specially equipped with a tearing device, which is used to put the organ tissue or the whole DPF pig into the tearing device for tearing, that is, a tearing device for tearing biological tissue is also provided on the crushing device 1. The tearing device includes two slide plates 4 arranged opposite to each other on the left and right. The two slide plates 4 are installed to slide in opposite directions in the vertical direction, for example, moving up and down. In specific practice, a claw rod 5 is fixed perpendicularly to the opposite side of each slide plate 4. These claw rods 5 are arranged in a rectangular array on the surface of the slide plate 4, and at the initial moment, such as Figure 1 As shown, the grab bars on the left and right sides are staggered to fully dismember and tear the biological waste tissue or organ to be processed. During the specific production, the claw rods 5 on each side are axially slidably extended into a vertical plate 6, and the vertical plate 6 is vertically slidably installed in the casing 8. A baffle 24 is fixed to the front and rear sides of the two vertical plates 6, and the front and rear side surfaces of the vertical plates 6 are respectively matched with the front and rear baffles 24 in sliding contact, so that the vertical plates 6 and the baffles 24 can enclose a tearing cavity 10 similar to a rectangle, and the biological waste to be processed is pulled, torn, and dismembered in this tearing cavity 10. Specifically, at the initial moment, the free ends of the claw rods 5 on the opposite sides are respectively located in the sockets on their corresponding vertical plates 6, and the two slides 4 are moved by a driving component according to the following path: that is, during operation, the two slides 4 are moved from as follows Figure 1 The initial positions shown are first translated toward each other so that each claw rod 5 extends out of the insertion hole and can penetrate into the biological tissue falling into the tearing cavity 10, and then the two slides 4 move away from each other in the vertical direction, and the claw rods 5 on the left and right sides tear the biological tissue apart so that it can be put into the crushing device for crushing.

[0024] More specifically, if Figure 3As shown, on one side of one of the vertical plates 6 facing the tearing cavity 10, one end of a gate plate 7 is specially hinged. This gate plate 7 is mainly used to place biological waste that falls into the tearing cavity 10, and this gate plate 7 can be adaptively opened and closed. The specific structure is: a conductive and magnetic guide block 18, such as an iron block, is embedded in the other end of the gate plate 7, and the gate plate 7 is made of a non-magnetic material, such as a plastic plate, to avoid overall conductivity and magnetism. Correspondingly, the vertical plate 6 and the baffle 24 can also be made of insulating materials, or sprayed with an insulating layer. Another necessary structure is that a conductive strip 11 that can vertically slide with the guide block 18 needs to be vertically fixed and embedded on the side of the other vertical plate 6 facing the tearing cavity 10. This conductive strip 11 is connected in a circuit, and the guide block 18 is also linked in the circuit. When the two are in contact, the circuit is closed, so that the electromagnet is energized. During the specific production, an insulating coating can be sprayed locally in the embedded groove for the conductive block, or on the vertical plate 6 around it. If necessary, a non-magnetic coating can also be sprayed. In the above structural design, as a specific implementation structure, an electromagnet and a permanent magnet 12 are fixedly installed inside the vertical plate 6 behind the conductive strip 11. The permanent magnet 12 can attract the gate plate 7 in a vertical suspension state upward, so that the guide block 18 is in contact with the conductive strip 11. However, although the gate plate 7 can be in a horizontal position at this time, the magnetic attraction of the permanent magnet alone is not enough to support the biological organ waste that falls on the gate plate 7, especially the whole DPF pig carcass. Therefore, in this embodiment, it is also necessary to make the guide block 18 and the conductive strip 11 in contact with each other. After contacting with the conductive strip 11, the electromagnet is energized and the guide block 18 is firmly adsorbed on the conductive strip 11. The permanent magnet only moves the gate plate 7 to the position where the guide block 18 can contact the conductive strip 11. The electromagnet is the main component for fixing the gate plate 7 and supporting the biological waste. Moreover, the electromagnet can adjust the current and flexibly improve the supporting capacity of the gate plate 7, which the permanent magnet 12 cannot do. If the magnetism is too large, it will generate too much resistance when the two slides 4 move. If it is too small, it will lead to insufficient bearing capacity of the gate plate 7. Therefore, the above-mentioned electromagnet synergistic effect is very effective.

[0025] like Figure 4-5 As shown, one side of the guide block 18 has a sliding column 19, which is horizontally slidably installed in the end surface of the gate plate 7 and connected to the second spring 20 in the end surface of the gate plate 7 to achieve telescopic installation. When the guide block 18 contacts the conductive strip 11, the second spring 20 must be in a compressed state to ensure reliable contact with the conductive strip 11 and avoid functional failure caused by poor contact after long-term wear. Figure 5As shown, it is best to have the sliding column 19 and the guide block 18 both be horizontally arranged columnar structures. Specifically, the two can be integrally formed and fixed as a whole, and horizontally slide in the center of the end face of the gate plate 7, protected inside the gate plate 7, and only the end of the guide block 18 is exposed and in contact with the conductive strip 11, which is safer and more reliable.

[0026] In practice, Figure 1 As shown, in this embodiment, a drive shaft 9 is fixed perpendicularly to the surface of the two slide plates 4 facing each other. The drive shaft 9 is vertically slidably installed in a vertical slide hole in the housing 8. The vertical slide hole is used to control the movement stroke of the slide plate 4. Specifically, for a one-way stroke, the length of the vertical slide hole must be such that the claw rods 5 on the left and right sides are moved from the initial crossed position, that is, Figure 1 The above-mentioned drive shaft 9 can be connected with a horizontal telescopic cylinder and a vertical telescopic cylinder to realize the horizontal movement and vertical movement of the drive shaft 9 respectively.

[0027] In order to tear biological organ waste more fully, the cross-section of the claw rod 5 is square, and one of the diagonals of the cross-section is in the vertical direction to form a certain cutting force, but this is not a sharp cutting, which is conducive to the dismemberment effect produced by rapid tearing rather than the cutting effect produced by incision. In order to facilitate the penetration of waste, the free end of the claw rod 5 is a pointed end.

[0028] As another implementation structure, such as Figure 1 and Figure 3The slide plate 4 on the left side moves vertically downward at the initial moment, and the vertical plate 6 on the left side and the housing 8 enclose a rectangular cavity 17, in which a piston plate 14 is vertically slidably installed, and the space below the piston plate 14 is used to store the inactivation liquid. The bottom of the rectangular cavity 17 is connected to an annular infusion ring 22 through an infusion pipeline 21, and a control valve such as a safety valve or a pressure relief valve can be installed on the infusion pipeline 21 to allow the fluid to pass unidirectionally under a certain pressure. More specifically, the infusion ring 22 is connected to the second inactivation device 3 through a plurality of radial branches 23, and the biological inactivation liquid is evenly dispersed in the second inactivation device 3, and a stirring rod 301 is provided in the second inactivation device 3, which is conducive to the full contact between the broken bones and the inactivation liquid to achieve protein denaturation and inactivation. In addition, the upper surface of the piston plate 14 is connected to a connecting arm 16 through a T-shaped slider 15. The T-shaped slider 15 is horizontally slidably installed in the T-shaped slide groove on the surface of the piston plate 14. The top end of the connecting arm 16 is fixed to the bottom of the slide plate 4 it faces. At the initial moment, the piston plate 14 is located below the vertical bar hole 801 to prevent the inactivation liquid from leaking out. When the slide plate 4 moves, it automatically presses the piston plate 14 downward to inject the inactivation liquid into the second inactivation device 3, which is especially necessary when the second inactivation device 3 itself is higher than the piston plate 14.

[0029] The present invention is not limited to the field involved in this implementation case, and some well-known structures or principles are not further described. However, ordinary technicians in the relevant field can theoretically know all the well-known technologies in this technical field before the application date or priority date, can fully master all the existing technologies in this technical field, and have the means and ability to apply these existing technologies for actual design and application. Under the technical enlightenment given by this application, technicians can improve and implement the present invention more comprehensively in combination with their own abilities. In addition, it should be pointed out that although the text and graphics of the above embodiments have shown the specific implementation occasions of the present invention, for ordinary technicians in this field, it is entirely possible to carry out a variety of obvious expansions and extensions on these embodiments without departing from the design concept of the present invention to form different embodiments, but this does not affect the scope of protection of the present invention, which is covered and embodied by the technical features of the claims and equivalent technical features.
