Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, in particular to a device for destroying residual liquid of narcotic drugs by high-temperature heat treatment. Background Art

[0002] Anesthetics, a general term for anesthetics and psychotropic drugs, play an indispensable therapeutic role in medicine due to their unique pharmacological properties. Whether providing deep anesthesia during surgery, alleviating symptoms of mental illness, or providing palliative care for cancer pain patients, anesthetics play a key role. However, the disposal of residual liquids from these drugs, due to their potential social and environmental risks, has become a critical issue in medical management that needs to be addressed.

[0003] At present, medical institutions generally adopt the "non-real-time + irregular + manual" method to deal with the residual liquid of narcotic drugs. This traditional treatment mode relies on manual operation by medical staff, including the collection, recording, transfer and final disposal of the residual liquid; in the specific process, medical staff need to manually register the amount of residual liquid after the use of the drug, temporarily store the residual liquid in a specific container, and then transport it to the hospital waste disposal department within the specified time.

[0004] However, this manual processing method is prone to human errors or illegal operations, resulting in loopholes in supervision and increasing the risk of residual narcotic drugs illegally flowing into other channels. To effectively deal with this risk, destruction equipment can be used at the site of drug use to carry out on-site harmless treatment and destruction of residual narcotic drugs, but there is still a lack of effective harmless treatment equipment. Summary of the Invention

[0005] Based on this, it is necessary to provide a high-temperature heat treatment and destruction device for the residual narcotic drug liquid to address the problem of incomplete treatment of the residual narcotic drug liquid in the current treatment process.

[0006] The above purpose is achieved through the following technical solutions:

[0007] A device for destroying residual narcotic drug liquid by high-temperature heat treatment, comprising:

[0008] A housing having a narcotic drug residual liquid destruction chamber, the housing being provided with a narcotic drug residual liquid injection port and an exhaust gas exhaust port both communicating with the narcotic drug residual liquid destruction chamber, the narcotic drug residual liquid injection port being configured to receive narcotic drug residual liquid; the exhaust gas exhaust port being configured to discharge gas generated by thermal decomposition of the narcotic drug residual liquid;

[0009] a heat source configured to heat the residual anesthetic drug solution;

[0010] The heat source includes a plurality of pairs of electric heating plates, which are arranged in parallel, and the two electric heating plates in the same pair are hingedly connected to form a V-shaped structure; the high-temperature heat treatment and destruction device for the residual narcotic drug liquid also includes an electric atomizing nozzle, which is located in the residual narcotic drug liquid destruction chamber and is connected to the residual narcotic drug liquid injection port, and is configured to atomize the residual narcotic drug liquid and spray it onto the plate surface of the electric heating plate;

[0011] The angle of the V-shaped structure formed by the two electric heating plates in the same pair can be changed; the high-temperature heat treatment and destruction device for residual narcotic drug liquid also includes an adjustment mechanism, which is configured to adjust the angle of the V-shaped structure formed by the two electric heating plates in the same pair in inverse proportion to the power of the electric atomizing nozzle.

[0012] Furthermore, the adjustment mechanism includes a pushing member, which is partially located in the narcotic drug residual liquid destruction chamber and divides the narcotic drug residual liquid destruction chamber into two sub-chambers. The pushing member can slide in a direction perpendicular to the parallel direction of the electric heating plates; multiple pairs of the electric heating plates located on the same side are hinged on the pushing member, and multiple pairs of the electric heating plates located on the other side are hinged on the casing.

[0013] 18. The swiftly and minutely adjusting device for a wood-planer working table as claimed in claim 1, wherein said linking rod and said adjusting base are pivotally connected to each other with a bolt, and said bolt has a round shank to contact with said linking rod. said linking rod has a first end and a second end, and said bolt has a round shank to contact with said linking rod.

[0014] Furthermore, a plurality of strip-shaped protrusions are provided on the surface of each of the electric heating plates, and the plurality of strip-shaped protrusions on the same electric heating plate are arranged in parallel and at intervals.

[0015] Furthermore, the casing also has a collection chamber, which is located below the narcotic drug residual liquid destruction chamber and is connected to the narcotic drug residual liquid destruction chamber through a connecting portion, and the collection chamber is configured to collect the narcotic drug residual liquid; the collection chamber has a lowest area, and the lowest area is configured to gather the narcotic drug residual liquid; the narcotic drug residual liquid high-temperature heat treatment destruction device also includes a suction piece, the suction port of the suction piece is connected to the lowest area, and the discharge port of the suction piece is connected to the narcotic drug residual liquid injection port.

[0016] Furthermore, the connecting portion is a conical ring structure with the larger end at the top.

[0017] The beneficial effects of the present invention are:

[0018] The present invention provides a high-temperature heat treatment and destruction device for residual narcotic drug liquid. By setting an adjustment mechanism, the angle of the V-shaped structure formed by two electric heating plates in the same pair can be adjusted in inverse proportion according to the power of the electric atomizing nozzle. Then, when the power of the electric atomizing nozzle is greater, the angle of the V-shaped structure formed by the two electric heating plates in the same pair is adjusted to be smaller, so that the spraying direction of the electric atomizing nozzle and the plate surface of the electric heating plate are closer to a vertical arrangement, so that most of the atomized residual narcotic drug liquid can adhere to the plate surface of the electric heating plate, thereby reducing the aggregation efficiency of the residual narcotic drug liquid and reducing the situation where the concentration of the residual narcotic drug is too high due to aggregation and incomplete decomposition.

[0019] Furthermore, by arranging the first elastic member, the second elastic member and the pushing member to be able to slide back and forth in a direction perpendicular to the parallel direction of the electric heating plates, during use, the pushing member can drive different pairs of adjacent electric heating plates to approach and move away from each other, wherein when different pairs of adjacent electric heating plates approach each other, the plate surfaces of different pairs of adjacent electric heating plates can overlap with each other and then rub against each other, thereby rubbing off impurities adhering to the plate surfaces of the electric heating plates, reducing the influence on the heat transfer efficiency between the electric heating plates and the residual liquid of the narcotic drug, and compressing the first elastic member and the second elastic member at the same time; when different pairs of adjacent electric heating plates move away from each other, the first elastic member and the second elastic member are released, causing the electric heating plates to vibrate, thereby shaking off or loosening impurities adhering to the plate surfaces of the electric heating plates, thereby improving the subsequent cleaning effect.

[0020] Furthermore, by providing strip-shaped protrusions, in the process of the pushing member driving different pairs of adjacent electric heating plates to approach each other, under the action of the first elastic member, the second elastic member and the strip-shaped protrusions, different pairs of adjacent electric heating plates can be rubbed and vibrated at the same time, thereby improving the cleaning effect of impurities adhered to the plate surface of the electric heating plate.

[0021] Furthermore, by providing a collection chamber, undecomposed narcotic drug residual liquid can be collected; by providing a suction piece, the narcotic drug residual liquid collected in the collection chamber can be transported back to the narcotic drug residual liquid destruction chamber for decomposition, thereby helping to improve the decomposition rate of the narcotic drug residual liquid.

[0039] There is currently no method to promptly handle / destroy the remaining narcotic liquid in medical institutions, pharmacies and other places after use. If the remaining narcotic liquid cannot be destroyed in a timely manner, the remaining narcotic liquid will flow into society, thereby posing a huge social security risk to society.

[0040] Through a narcotic drug residual liquid destruction device, the narcotic drug residual liquid left after use can be promptly processed / destroyed, making it completely harmless and non-toxic, thereby preventing the residual narcotic drug residual liquid from flowing into the society and reducing the social security risks brought to the society.

[0041] Narcotic drugs all have a vaporization (decomposition of active ingredients) temperature. The main principle of this device is to quickly heat the residual liquid of narcotic drugs to reach the set temperature. At the same time, the temperature in the device is monitored in real time through the temperature sensor to completely vaporize the narcotic drugs (decompose the active ingredients), thereby achieving non-toxic and harmless treatment.

[0042] like Figure 1 and Figure 2 As shown, the narcotic drug residual liquid destruction device provided by the first embodiment of the present invention is configured to include a heat source and a housing 1 having a narcotic drug residual liquid destruction chamber 101, wherein a narcotic drug residual liquid injection port 102 and an exhaust gas exhaust interface 103 both connected to the narcotic drug residual liquid destruction chamber 101 are provided on the housing 1, the narcotic drug residual liquid injection port 102 is configured to receive narcotic drug residual liquid; the exhaust gas exhaust interface 103 is configured to discharge the gas generated after the narcotic drug residual liquid is heated and decomposed; the heat source is configured to heat the narcotic drug residual liquid.

[0043] Specifically, in this embodiment, to facilitate the formation of a narcotic drug destruction chamber 101, a first circular mounting hole is formed through the front side wall of the housing 1. A base cylinder 106 is fixedly mounted within the housing 1. The axis of the base cylinder 106 extends horizontally in the front-to-back direction and coincides with the center of the first mounting hole. The rear end of the base cylinder 106 is suspended and inserted into the interior of the housing 1, while the front end is open and fixed to the front inner wall of the housing 1. A cover plate 8 is sealed at the front end of the base cylinder 106, which is fixedly connected to the front outer wall of the housing 1 by bolts. The narcotic drug destruction chamber 101 is formed by the base cylinder 106 and the cover plate 8. To reduce heat loss from the narcotic drug destruction chamber 101, an insulation layer 6 is filled between the housing 1 and the base cylinder 106.

[0044] In order to facilitate the formation of the narcotic drug residual liquid injection port 102, a liquid inlet pipe 2 is inserted on the cover plate 8. The liquid inlet pipe 2 is an L-shaped structure and has a first vertical section and a first inclined section. The angle between the first vertical section and the first inclined section is an obtuse angle, wherein the first vertical section extends in the vertical direction when installed and is located on the front side of the cover plate 8, and the first inclined section extends obliquely in the lower rear direction when installed, and passes through the cover plate 8 and is inserted in the narcotic drug residual liquid destruction chamber 101. The narcotic drug residual liquid injection port 102 is formed at the pipe mouth of the liquid inlet pipe 2. A filter plate 5 is provided at the narcotic drug residual liquid injection port 102. The filter plate 5 has a circular structure and is coaxially and fixedly inserted into the top of the first vertical section of the liquid inlet pipe 2 during installation. The filter plate 5 is configured to filter out debris such as injection needles and pen cores to prevent them from falling into the narcotic drug residual liquid destruction chamber 101, causing them to react with the narcotic drug residual liquid under high temperature conditions and further generate toxic gases.

[0045] In order to facilitate the formation of the exhaust gas exhaust interface 103, an exhaust gas exhaust pipe 3 is provided on the first vertical section of the liquid inlet pipe 2. The exhaust gas exhaust pipe 3 is an L-shaped structure and has a second vertical section and a second inclined section. The angle between the second vertical section and the second inclined section is an obtuse angle, wherein the second vertical section extends in the vertical direction during installation and is located on the right side of the liquid inlet pipe 2, and the second inclined section extends obliquely in the lower left direction during installation, and passes through the circumferential side wall of the first vertical section of the liquid inlet pipe 2. A hot gas baffle 301 is provided at the end of the second inclined section. The hot gas baffle 301 is an arc-shaped structure and is coaxially arranged with the second inclined section. The hot gas baffle 301 is inserted in the first vertical section of the liquid inlet pipe 2, and the inner arc surface of the hot gas baffle 301 is arranged downward to ensure that the hot gas in the liquid inlet pipe 2 can be effectively blocked from being discharged through the narcotic drug residual liquid injection port 102 to avoid harming the operator; the exhaust gas interface 103 is formed at the pipe mouth of the exhaust gas exhaust pipe 3.

[0046] In order to reduce the spillage of residual narcotic drug liquid, a liquid guiding cone ring 7 is coaxially inserted at the top of the first vertical section of the liquid inlet pipe 2 and on the upper side of the filter plate 5. The large end of the liquid guiding cone ring 7 is at the top when installed, so that when the residual narcotic drug liquid is poured in, the large-diameter top of the liquid guiding cone ring 7 can effectively receive the spilled residual narcotic drug liquid, forming an initial interception. After the residual narcotic drug liquid contacts the conical surface, it is affected by gravity and surface tension and converges downward along the smooth conical surface. It is accurately introduced into the interior of the liquid inlet pipe 2 through the small end of the cone ring. Even in the case of fast pouring speed or angle deviation, the cone ring structure can quickly adjust the liquid flow direction to prevent the residual narcotic drug liquid from splashing.

[0047] The heat source includes an electric heating wire 4 and is arranged between the rear inner wall of the housing 1 and the rear end of the base tube 106 during installation.

[0048] In order to improve the structure of the high-temperature heat treatment destruction device for residual narcotic drug liquid, a temperature controller 9, a power meter 10, a power switch 11, a heating switch 12, an alarm button 13 and a communication interface 14 are arranged in sequence on the left side wall of the casing 1 from back to front.

[0049] During use, first, the high-temperature heat treatment destruction device for residual narcotic drug liquid is connected to the power supply, and then the temperature controller 9 is set to the relevant temperature. Then, the power switch 11 and the heating switch 12 are turned on, and the narcotic drug residual liquid remaining after use is quickly heated to the set temperature through the electric heating wire 4. Then, the narcotic drug residual liquid remaining after use is injected into the device through the narcotic drug residual liquid injection port 102, so that the injected narcotic drug residual liquid is quickly destroyed / decomposed into the effective components in the narcotic drug residual liquid destruction chamber 101. The temperature controller 9 can provide real-time feedback on the temperature in the narcotic drug residual liquid destruction chamber 101, and the power meter 10 can provide real-time feedback on the power in the device, so as to ensure that the narcotic drug residual liquid in the device can be safely, controllably and thoroughly destroyed. The waste gas after the destruction of the narcotic drug residual liquid is discharged through the waste gas exhaust pipe 3 and the waste gas exhaust interface 103, thereby achieving non-toxic and harmless treatment.

[0050] like Figures 3 to 12 As shown, the narcotic drug residual liquid destruction device provided by the second embodiment of the present invention is configured to include a heat source and a housing 1 having a narcotic drug residual liquid destruction chamber 101, wherein a narcotic drug residual liquid injection port 102 and an exhaust gas exhaust interface 103 both connected to the narcotic drug residual liquid destruction chamber 101 are provided on the housing 1, the narcotic drug residual liquid injection port 102 is configured to receive narcotic drug residual liquid; the exhaust gas exhaust interface 103 is configured to discharge the gas generated after the narcotic drug residual liquid is heated and decomposed; the heat source is configured to heat the narcotic drug residual liquid.

[0051] Specifically, in this embodiment, to facilitate the formation of a narcotic drug destruction chamber 101, the top of the housing 1 is open. A base box 107 is suspended within the housing 1, with both the top and front sidewalls of the base box 107 open. When installed, the front end of the base box 107 is vertically fixed to the front inner wall of the housing 1. A second circular mounting hole is formed through the front sidewall of the housing 1. A cover plate 8 blocks the second mounting hole and is bolted to the front outer wall of the housing 1. A top cover 108 is hingedly connected to the top of the housing 1 and fixed to the housing 1 with bolts and nuts during use. The narcotic drug destruction chamber 101 is enclosed by the base box 107, the cover plate 8, and the top cover 108. To reduce heat loss from the narcotic drug destruction chamber 101, an insulation layer 6 is placed between the housing 1 and the base box 107.

[0052] In order to facilitate the formation of the narcotic drug residual liquid injection port 102, a liquid inlet pipe 2 is inserted on the cover plate 8. The liquid inlet pipe 2 is an L-shaped structure and has a first vertical section and a first inclined section. The angle between the first vertical section and the first inclined section is an obtuse angle, wherein the first vertical section extends in the vertical direction when installed and is located on the front side of the cover plate 8, and the first inclined section extends obliquely in the lower rear direction when installed, and passes through the cover plate 8 and is inserted in the narcotic drug residual liquid destruction chamber 101. The narcotic drug residual liquid injection port 102 is formed at the pipe mouth of the liquid inlet pipe 2. A filter plate 5 is installed at the residual narcotic liquid injection port 102. This circular filter plate 5 is coaxially and securely mounted on the top of the first vertical section of the liquid inlet tube 2 during installation. The filter plate 5 is configured to filter debris such as injection needles and pen refills, preventing them from falling into the residual narcotic liquid destruction chamber 101 and reacting with the residual narcotic liquid under high temperature conditions, thereby producing toxic gases. To reduce spillage of residual narcotic liquid, a conical liquid guide ring 7 is coaxially mounted on the top of the first vertical section of the liquid inlet tube 2, above the filter plate 5, with the larger end facing upward during installation.

[0053] In order to facilitate the formation of the waste gas exhaust interface 103, a waste gas exhaust pipe 3 is vertically and penetratingly provided on the top cover 108. The waste gas exhaust pipe 3 is connected to the narcotic drug residual liquid destruction chamber 101, and the waste gas exhaust interface 103 is formed at the pipe mouth of the waste gas exhaust pipe 3.

[0054] In order to improve the structure of the high-temperature heat treatment destruction device for residual narcotic drug liquid, a temperature controller 9, a power meter 10, a power switch 11, a heating switch 12, an alarm button 13 and a communication interface 14 are arranged in sequence on the left side wall of the casing 1 from back to front.

[0055] The heat source includes multiple pairs of electric heating plates 15, which are arranged in parallel, and the two electric heating plates 15 of the same pair are hingedly connected to form a V-shaped structure; the high-temperature heat treatment destruction device for the residual narcotic drug also includes an electric atomizing nozzle 16, which is located in the residual narcotic drug destruction chamber 101 and is connected to the residual narcotic drug injection port 102, and is configured to atomize the residual narcotic drug and spray it onto the plate surface of the electric heating plate 15.

[0056] Specifically, the electric heating plate 15 is installed with the plate surface vertically arranged; multiple pairs of electric heating plates 15 are arranged side by side in the left-right direction; one electric heating plate 15 in the same pair has a T-shaped structure, and hinge columns are vertically and fixedly installed at the upper and lower ends of the small end of the electric heating plate 15. The other electric heating plate 15 has a U-shaped structure, and hinge holes are opened on the upper and lower ends of the notch of the electric heating plate 15, which are adjacent to each other. When the two electric heating plates 15 in the same pair are installed, the small end of the T-shaped structure is inserted into the notch of the U-shaped structure electric heating plate 15, and the hinge columns are rotated and inserted into the hinge holes, ensuring that the two electric heating plates 15 in the same pair can form a hinged fit. The electric atomizing nozzle 16 is inserted into the rear panel of the cover plate 8 and is connected to the liquid inlet pipe 2 to ensure that it can receive and atomize the residual narcotic drug liquid. Optionally, to improve the atomization efficiency of the residual narcotic drug liquid, the number of electric atomizing nozzles 16 can be set to two, and the two electric atomizing nozzles 16 are arranged at intervals in the left-right direction. Optionally, the electric heating plate 15 may be made of high thermal conductivity silicon carbide ceramics (thermal conductivity ≥ 150 W / m·K), and a nano-scale infrared radiation coating may be applied to the surface, thereby converting electrical energy into infrared heat energy and improving heat transfer efficiency.

[0057] During use, the high-temperature heat treatment destruction device for residual narcotic drug liquid is first connected to a stable power supply that meets the equipment requirements to ensure a safe and reliable power supply; then, based on the specific composition and destruction standards of the residual narcotic drug liquid, the target operating temperature is accurately set through the temperature controller 9; the temperature setting needs to be professionally evaluated to ensure that the residual narcotic drug liquid can be completely decomposed while avoiding unnecessary safety risks caused by excessively high temperatures.

[0058] After completing the temperature setting, turn on the power switch 11 and the heating switch 12 in sequence to start the heating system of the equipment; at this time, multiple pairs of electric heating plates 15 with a V-shaped hinged structure start to work. With their high thermal conductivity silicon carbide ceramic material and nano-scale infrared radiation coating, they can efficiently convert electrical energy into infrared heat energy and quickly heat up to the set temperature, thereby not only directly heating the residual narcotic drug liquid, but also simultaneously increasing the overall temperature in the narcotic drug residual liquid destruction chamber 101; through the layout of multiple groups of electric heating plates 15 arranged in parallel along the left and right directions, while improving the uniformity of temperature distribution in the narcotic drug residual liquid destruction chamber 101, it lays the foundation for the subsequent decomposition process.

[0059] When the electric heating plate 15 reaches the set temperature and stabilizes, the remaining narcotic drug liquid after use is injected into the liquid inlet pipe 2 through the narcotic drug liquid injection port 102. During this process, the filter plate 5 on the top of the liquid inlet pipe 2 will play a key role, effectively intercepting injection needles, pen refills and other debris, preventing them from entering the narcotic drug liquid destruction chamber 101 and reacting with the high-temperature residual liquid to produce toxic gases; at the same time, the liquid guide cone ring 7 can guide the residual liquid to flow smoothly into the liquid inlet pipe 2, reducing the spillage of the residual liquid; after the residual liquid enters the liquid inlet pipe 2, the electric atomizing nozzle 16 located on the rear plate surface of the cover plate 8 and connected to the liquid inlet pipe 2 is activated, and the electric atomizing nozzle 16 converts the liquid residual liquid into fine droplets and sprays them onto the surface of the electric heating plate 15; through the atomization process, the surface area of ​​the narcotic drug residual liquid is greatly increased, and its contact area with the heat source of the electric heating plate 15 is significantly increased, thereby effectively improving the decomposition efficiency.

[0060] During the decomposition process, the temperature controller 9 continuously monitors the temperature within the narcotic destruction chamber 101 in real time and feeds this data back to the control system. Any abnormal temperature fluctuations can be adjusted promptly to ensure the decomposition process proceeds stably within the set temperature range. Simultaneously, the power meter 10 monitors power changes within the device in real time, providing data support for evaluating the device's operating status and ensuring a safe and controllable destruction process. The coordinated action of multiple pairs of electric heating plates 15 ensures the complete decomposition of the narcotic, completely eliminating its potential hazards.

[0061] The waste gas generated by the high-temperature decomposition of the residual narcotic drug liquid is discharged from the waste gas exhaust interface 103 through the waste gas exhaust pipe 3 vertically penetrating the top cover 108; the discharged waste gas can be further purified according to environmental protection requirements to ensure that the final emission meets the harmlessness standard, thereby realizing the non-toxic and harmless treatment of the residual narcotic drug liquid from treatment to discharge.

[0062] Furthermore, in order to improve the applicability of the device for high-temperature heat treatment and destruction of residual liquid of narcotic drugs, the angle of the V-shaped structure formed by the two electric heating plates 15 in the same pair can be changed; the device for high-temperature heat treatment and destruction of residual liquid of narcotic drugs also includes an adjustment mechanism, which is configured to be able to adjust the angle of the V-shaped structure formed by the two electric heating plates 15 in the same pair in inverse proportion to the power of the electric atomizing nozzle 16.

[0063] Specifically, the adjustment mechanism is configured to include a pushing member 1701, which is partially located in the narcotic drug residual liquid destruction chamber 101 and divides the narcotic drug residual liquid destruction chamber 101 into two sub-chambers. The pushing member 1701 can slide in a direction perpendicular to the parallel direction of the electric heating plates 15; multiple pairs of electric heating plates 15 located on the same side are hinged on the pushing member 1701, and multiple pairs of electric heating plates 15 located on the other side are hinged on the casing 1.

[0064] More specifically, the pusher 1701 is a T-shaped structure and has a rod portion and a plate portion that are vertically connected, wherein the rod portion is vertical when installed and sequentially passes through the rear side wall of the casing 1 and the rear side wall of the base box 107, and is inserted into the base box 107; the plate portion is inserted into the base box 107 when installed, and the plate surface is vertical and arranged along the left and right directions, so that the narcotic drug residual liquid destruction chamber 101 can be divided into two front and rear sub-chambers, thereby ensuring that the atomized narcotic drug residual liquid is mainly diffused in the sub-chamber located on the front side, thereby ensuring the decomposition efficiency of the narcotic drug residual liquid; the pusher 1701 can slide in the front and rear directions, so that the angle of the V-shaped structure formed by the two electric heating plates 15 of the same pair can be changed through the hinged cooperation with the electric heating plate 15. Optionally, in order to achieve automatic control of the angle of the V-shaped structure formed by the two electric heating plates 15 of the same pair, a driving cylinder is provided on the rear side wall of the casing 1. The output shaft of the driving cylinder is horizontally and forwardly arranged and fixed to the end of the rod of the pushing member 1701 to ensure that the pushing member 1701 can be driven to slide in the front and rear directions.

[0065] It can be understood that the driving cylinder can be configured as any one of a hydraulic cylinder, a pneumatic cylinder or an electric cylinder.

[0066] During use, when the power of the electric atomizing nozzle 16 increases, the driving member 1701 moves forward, and the V-shaped angle of the same pair of electric heating plates 15 is synchronously reduced through the hinge structure. This linkage relationship is designed based on the principles of fluid mechanics to ensure the optimal match between the atomized particle size and the heating area. That is, the greater the power of the electric atomizing nozzle 16, the smaller the droplet size, and the larger the required heating contact area.

[0067] By adjusting the angle of the V-shaped angle of the same pair of electric heating plates 15, the spray direction of the electric atomizing nozzle 16 is gradually approached to a vertical state with respect to the plate surface of the electric heating plate 15. This orthogonal setting utilizes the fluid impact effect: when the droplets impact the heating surface at a 90° angle, the kinetic energy is converted into diffusion potential energy, forming a uniform liquid film distribution on the plate surface, which can reduce the rebound loss compared with the inclined impact; and under the synergistic effect of the front and rear chamber structures, the residual liquid of the atomized narcotic drug is confined to the front chamber for diffusion. As the V-shaped angle decreases, the effective heating area of ​​the electric heating plate 15 expands, forming a gradient increasing temperature field, forcing the droplets to complete the decomposition reaction in the high energy density area, and avoiding the migration and aggregation of undecomposed droplets to the rear chamber. Therefore, by dynamically matching the power of the electric atomizing nozzle 16 and the angle of the V-shaped angle of the same pair of electric heating plates 15, the high-temperature heat treatment and destruction device for narcotic drug residual liquid can maintain a high decomposition rate when treating narcotic drug residual liquids with different viscosities and different active ingredients, and essentially solve the contradiction between local overheating and incomplete decomposition caused by droplet convergence in traditional static heating devices.

[0068] Furthermore, when the narcotic drug is opened and used in the original glass bottle, it will inevitably be contaminated with glass fragments. After these glass fragments are mixed with the residual narcotic drug liquid, they will be sprayed onto the surface of the electric heating plate 15 along with the residual narcotic drug liquid. In a high temperature environment, the glass residues melt quickly and form sticky attachments, which cover the surface of the electric heating plate 15 and hinder heat transfer, thereby reducing the heat transfer efficiency between the electric heating plate 15 and the residual narcotic drug liquid, affecting the decomposition effect of the residual narcotic drug liquid.

[0069] In order to effectively solve this problem, it is set that the pushing member 1701 can slide back and forth in a direction perpendicular to the parallel direction of the electric heating plates 15; the pushing member 1701 is provided with a plurality of first slide grooves 1702, the first slide grooves 1702 extend in a direction parallel to the parallel direction of the electric heating plates 15, and the plurality of first slide grooves 1702 are arranged at intervals in a direction parallel to the parallel direction of the electric heating plates 15; the housing 1 is provided with a plurality of second slide grooves 1703, the second slide grooves 1703 extend in a direction parallel to the parallel direction of the electric heating plates 15, and the plurality of second slide grooves 1703 are arranged in a direction parallel to the parallel direction of the electric heating plates 15. The electric heating plates 15 are arranged at intervals in the direction of rotation; multiple pairs of electric heating plates 15 located on the same side are provided with a first slider 1704, which is slidably inserted in the first slide groove 1702; multiple pairs of electric heating plates 15 located on the other side are provided with a second slider 1705, which is slidably inserted in the second slide groove 1703; each first slider 1704 is connected to the pushing member 1701 through a first elastic member, and the first elastic member is inserted in the first slide groove 1702; each second slider 1705 is connected to the casing 1 through a second elastic member, and the second elastic member is inserted in the second slide groove 1703.

[0070] Specifically, to facilitate the formation of the first chute 1702, a base plate 17011 is vertically and fixedly provided on the upper and lower end surfaces of the plate portion of the pusher 1701. The first chute 1702 is provided on the base plate 17011 and is located on the front side of the plate portion of the pusher 1701. The first chute 1702 extends in the left-right direction, and multiple first chute 1702 are evenly spaced along the left-right direction. The second chute 1703 is provided on the inner bottom surface of the base box 107. The second chute 1703 and the first chute 1702 are spaced apart in the front-to-back direction. The second chute 1703 extends in the left-right direction, and multiple second chute 1703 are evenly spaced along the left-to-right direction. The second chute 1703 and the first chute 1702 are arranged in a corresponding manner. The first slider 1704 is hinged to the bottom of the electric heating plate 15 located at the rear side and is disposed away from the hinge point. The second slider 1705 is hinged to the bottom of the electric heating plate 15 located at the front side and is disposed away from the hinge point. The first elastic member is a first compression spring 1706, which is inserted into the first chute 1702 and located to the left of the first slider 1704. When installed, the right end of the first compression spring 1706 is fixedly connected to the left wall of the first slider 1704, and the left end is fixedly connected to the base plate 17011. Under the action of the first compression spring 1706, the first slider 1704 has a tendency to move rightward. The second elastic member is a second compression spring 1707, which is inserted into the second chute 1703 and located to the left of the second slider 1705. When installed, the right end of the second compression spring 1707 is fixedly connected to the left wall of the second slider 1705, and the left end is fixedly connected to the base box 107. Under the action of the second compression spring 1707, the second slider 1705 has a tendency to move rightward.

[0071] Initially, under the action of the first compression spring 1706 , the first slider 1704 abuts against the right end of the first sliding groove 1702 , and under the action of the second compression spring 1707 , the second slider 1705 abuts against the right end of the second sliding groove 1703 .

[0072] During use, the pushing member 1701 is first driven to move forward, and the pushing member 1701 simultaneously drives the electric heating plate 15 located at the rear side to move forward through the first slide groove 1702 and the first slider 1704. The electric heating plate 15 located at the rear side is synchronously hinged with the electric heating plate 15 located at the front side, so that the angle of the V-shaped structure formed by the two gradually decreases.

[0073] When the surfaces of the different pairs of electric heating plates 15 on the same side overlap, as the pushing member 1701 continues to move, for the adjacent different pairs of electric heating plates 15, under the clamping of the pair of electric heating plates 15 on the right, the pair of electric heating plates 15 on the left moves to the left, and the angle of the V-shaped structure formed by the two continues to decrease, and then they can rub each other, so as to rub off the impurities adhering to the surface of the electric heating plates 15, thereby reducing the influence on the heat transfer efficiency between the electric heating plates 15 and the residual liquid of the narcotic drug; at this time, the pair of electric heating plates on the left The first slider 1704 on 15 moves to the left along the first slide groove 1702, and the second slider 1705 moves to the left along the second slide groove 1703, and the corresponding first compression spring 1706 and second compression spring 1707 are compressed synchronously; thereby, the further to the left, the smaller the angle of the V-shaped structure formed by the same pair of electric heating plates 15 is, and the farther the first slider 1704 moves to the left along the first slide groove 1702, the farther the second slider 1705 moves to the left along the second slide groove 1703, and the greater the degree of compression of the first compression spring 1706 and the second compression spring 1707.

[0074] When the pushing member 1701 moves to the extreme position, the pushing member 1701 is driven to move backward, and the pushing member 1701 synchronously drives the electric heating plate 15 located on the rear side to move backward through the first slide groove 1702 and the first slider 1704, and the electric heating plate 15 located on the rear side is synchronously hinged with the electric heating plate 15 located on the front side, so that the angle of the V-shaped structure formed by the two gradually increases; at this time, the first compression spring 1706 and the second compression spring 1707 are both released, causing the electric heating plate 15 to generate a swing acceleration, thereby stimulating the electric heating plate 15 to generate high-frequency micro-vibration, so that impurities adhering to the plate surface of the electric heating plate 15 can be shaken off or loosened, thereby improving the subsequent cleaning effect.

[0075] The above process is repeated, so that based on the synergistic effect of mechanical transmission and elastic coupling, the electric heating plate 15 generates regular vibration and displacement changes, thereby effectively removing glass residues on the surface of the electric heating plate 15.

[0076] Furthermore, in order to improve the cleaning effect of glass residues on the electric heating plate 15, a plurality of strip-shaped protrusions 1501 are provided on the plate surface of each electric heating plate 15, and the plurality of strip-shaped protrusions 1501 on the same electric heating plate 15 are arranged in parallel and at intervals.

[0077] Specifically, the strip-shaped protrusions 1501 extend in the vertical direction, and multiple strip-shaped protrusions 1501 on the same electric heating plate 15 are arranged in parallel and at equal intervals. Optionally, the cross-sectional shape of the strip-shaped protrusions 1501 can be set to be triangular, arc-shaped, etc.

[0078] During use, when the surfaces of different pairs of electric heating plates 15 on the same side rub against each other, the electric heating plates 15 can vibrate under the action of the strip-shaped protrusions 1501, thereby improving the cleaning effect of impurities adhering to the surfaces of the electric heating plates 15.

[0079] Furthermore, in order to achieve both complete decomposition of the residual narcotic drug liquid and cleaning of the casing 1, it is provided that the casing 1 also has a collecting chamber 104, which is located below the narcotic drug residual liquid destruction chamber 101 and is connected to the narcotic drug residual liquid destruction chamber 101 through a connecting portion 105, and the collecting chamber 104 is configured to collect the narcotic drug residual liquid; the collecting chamber 104 has a lowest area 1041, and the lowest area 1041 is configured to gather the narcotic drug residual liquid; the narcotic drug residual liquid high-temperature heat treatment destruction device also includes a suction piece, the suction port of the suction piece is connected to the lowest area 1041, and the discharge port of the suction piece is connected to the narcotic drug residual liquid injection port 102.

[0080] Specifically, to facilitate the formation of the collection chamber 104, a collection box 109 is provided at the bottom of the housing 1, and the collection chamber 104 is formed in the collection box 109. To facilitate the communication between the collection chamber 104 and the narcotic drug residual liquid destruction chamber 101, the top of the collection box 109 is open, and a communication port 1010 is provided at the bottom of the housing 1. The communication port 1010 is connected to the collection box 109. A plurality of communication holes 1071 are provided at the bottom of the base box 107. The communication holes 1071 are strip-shaped and extend in the front-to-back direction. The plurality of communication holes 1071 are evenly spaced along the left-to-right direction. The communication portion 105 is provided between the bottom of the base box 107 and the bottom of the housing 1, and connects the communication holes 1071 and the communication port 1010, ensuring that the narcotic drug residual liquid in the base box 107 can be introduced into the collection box 109. To facilitate the formation of the lowest region 1041, the bottom of the collection box 109 is configured in a V-shaped structure extending in the front-to-back direction. The V-shaped structure's opening faces upward, with a higher rear end and a lower front end. This results in the lowest region 1041 being formed at the front end of the middle portion of the bottom of the collection box 109, ensuring that the remaining narcotic liquid within the collection box 109 can be directed into the lowest region 1041. The suction element is a gas-liquid pump 18, which is mounted on the front outer wall of the housing 1 during installation. The suction port of the gas-liquid pump 18 communicates with the lowest region 1041 via a connecting pipe 1801, while the discharge port of the gas-liquid pump 18 communicates with the residual narcotic liquid injection port 102 via a connecting pipe 1801. To filter the liquid delivered by the gas-liquid pump 18, a filter disc 19 is coaxially and fixedly mounted within the first inclined section of the liquid inlet pipe 2. The filter disc 19 is configured to filter the liquid.

[0081] During use, part of the undecomposed narcotic drug residual liquid enters the collection box 109 through the connecting hole 1071, the connecting portion 105 and the connecting port 1010 in sequence, and then gathers to the lowest area 1041 under the guidance of the inclined V-shaped structure at the bottom of the collection box 109; at the same time, the gas-liquid integrated pump 18 is started to transport the narcotic drug residual liquid from the lowest area 1041 to the liquid inlet pipe 2, so that this part of the narcotic drug residual liquid can be decomposed again by high temperature, thereby helping to improve the decomposition rate of the narcotic drug residual liquid.

[0082] When the amount of residual narcotic drug in the narcotic drug destruction chamber 101 is small, clean water is introduced into the narcotic drug destruction chamber 101 through the liquid inlet pipe 2, and the clean water is sprayed out through the electric atomizing nozzle 16 and falls on the electric heating plate 15, which not only flushes the impurities on the electric heating plate 15, but also flushes the casing 1. The clean water then carries the impurities and the residual narcotic drug through the connecting hole 1071, the connecting part 105 and the connecting port 1010 in sequence into the collection box 109, and then, under the guidance of the inclined V-shaped structure at the bottom of the collection box 109, it converges to the lowest area 1041, and then is transported from the lowest area 1041 to the liquid inlet pipe 2 by the gas-liquid integrated pump 18, so that this part of the residual narcotic drug can be decomposed again by high temperature, thereby helping to improve the decomposition rate of the residual narcotic drug.

[0083] Furthermore, in order to improve the collection efficiency of the collection box 109, the connecting portion 105 is configured to be a conical ring structure with the larger end at the top.

[0084] Specifically, the connecting portion 105 is a pyramidal ring structure, and the large end is connected to the connecting hole 1071, so that it can receive the falling liquid from the narcotic drug residual liquid destruction chamber 101 to the maximum extent, and effectively avoid the splashing and blockage of liquid flow caused by sudden change of caliber; the small end is connected to the connecting port 1010, and through the gradually shrinking diversion channel, the synergistic effect of gravity and fluid pressure is used to naturally accelerate the narcotic drug residual liquid during the flow process, thereby improving the diversion efficiency.

[0085] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0086] The above-described embodiments merely illustrate several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that variations and modifications are possible without departing from the scope of the present invention, and such variations and modifications are fully within the scope of protection of the present invention.
