Description

Technical Field

[0001] This utility model relates to the field of irradiation technology, and in particular to an irradiation reactant discharge device with a purification structure. Background Technology

[0002] The irradiator reactant discharge device is a component used to safely remove materials or waste gas after irradiation reaction. It consists of a conveying pipe, valves, and a power unit to ensure the orderly discharge of reactants and avoid retention. The discharge device with a purification structure can perform harmless treatment of reactants and is closely related to the environmental protection operation of the irradiator. After irradiation reaction, the materials or gases are discharged through the conveying pipe of the discharge device and enter the filtration, adsorption, or degradation components in the purification structure. The purification structure removes harmful substances through activated carbon, UV photolysis, etc., and discharges them only after they meet the standards.

[0003] In the prior art, some irradiator reactant discharge devices achieve safe and orderly discharge of irradiator reactants through a closed-loop process. After the reactants are discharged from the irradiation reaction chamber through a sealed delivery pipe, they first enter the buffer chamber. The flow rate is stabilized by the built-in guide plate to avoid pressure fluctuations affecting the discharge stability. Subsequently, the material flows into the separation module, where the solid reaction residue is separated from the liquid or gaseous products by the dual action of gravity settling and filter screen filtration.

[0004] However, in actual use, some irradiators produce toxic gases, unreacted chemical residues, and even trace amounts of radioactive aerosols in their exhaust gas during reactant processing. If purification fails, these substances will be directly released into the atmosphere, causing local air pollution. To address the above issues, an irradiator reactant discharge device with a purification structure is proposed. Utility Model Content

[0005] This invention proposes an irradiator reactant discharge device with a purification structure, which aims to improve the problem that some existing irradiator reactant discharge devices with purification structures are difficult to purify and discharge exhaust gas.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An irradiator reactant discharge device with a purification structure includes an outer shell, with a support frame fixedly connected to each of the four inner corners of the outer shell, a load-bearing frame fixedly connected to the outside of the support frame, a reaction chamber fixedly connected to the top of the load-bearing frame, a tail gas emission anti-backflow mechanism fixedly connected to the top of the reaction chamber, and a disassembly and assembly mechanism fixedly connected to the rear outer side of the reaction chamber. The exhaust gas backflow prevention mechanism includes a mounting housing, which is fixedly connected to the outside of the reaction chamber. An exhaust gas purification component is installed inside the mounting housing. An exhaust pipe is fixedly connected to the rear side of the outside of the mounting housing. A connecting housing is fixedly connected to the top of the exhaust pipe. A cross-shaped placement plate is fixedly connected to the top inside the connecting housing. A placement housing is fixedly connected to the bottom of the cross-shaped placement plate. A sliding rod is slidably connected to the bottom outside of the placement housing. A return spring is sleeved on the outside of the sliding rod.

[0007] The above solution provides a stable support for the reaction chamber via the internal support frame and load-bearing frame. The exhaust gas is treated by the backflow prevention mechanism. The purification components installed on the housing purify the exhaust gas. When the exhaust pipe is used for delivery, the sliding rod, in conjunction with the reset spring, slides on the housing to prevent backflow of external airflow. The cross-shaped placement plate enhances structural stability, ensures clean emissions and prevents backflow, and improves the safety and purification reliability of the device.

[0008] As a further description of the above technical solution: A pipe is fixedly connected to the top of the reaction chamber, and a negative pressure fan is fixedly connected to the outside of the pipe. The outside of the mounting housing is fixedly connected to the output end of the negative pressure fan.

[0009] The above solution involves connecting a negative pressure fan to the top of the reaction chamber, with the fan's output connected to the mounting housing. The negative pressure fan provides power to efficiently draw the exhaust gas from the reaction chamber into the mounting housing, where it is treated by internal purification components before being discharged. Stable power transmission ensures no residue in the exhaust gas, and the purification structure enhances exhaust gas treatment efficiency, guarantees clean emissions, and strengthens the practicality and safety of the device.

[0010] As a further description of the above technical solution: A sealing plate is fixedly connected to the outside of the sliding rod, and a sealing ring is fixedly connected to the bottom of the outside of the connecting housing. The outside of the sealing ring is in contact with the outside of the sealing plate, and a pull plate is slidably connected to the outside of the mounting housing.

[0011] The above solution ensures a tight seal between the external sealing plate of the sliding rod and the sealing ring at the bottom of the connecting housing, enhancing backflow prevention and preventing external airflow from contaminating the reaction chamber. The external sliding pull plate facilitates the disassembly and maintenance of the exhaust gas purification components, making operation convenient. The robust and reliable sealing structure guarantees clean, one-way exhaust gas emission, and the pull plate design improves component replacement efficiency.

[0012] As a further description of the above technical solution: The exhaust gas purification component includes a dustproof net, the outside of which is fixedly connected to the inside of the mounting housing. A sponge board is fixedly connected to the front inside of the mounting housing, a perforated filter plate is fixedly connected to the inside of the mounting housing, and an activated carbon adsorption plate is fixedly connected to the rear inside of the mounting housing.

[0013] The above solution utilizes a multi-layered structure in the exhaust gas purification system: a dust filter initially intercepts impurities, a sponge plate filters fine particulate matter, a perforated filter plate further filtrations, and an activated carbon adsorption plate adsorbs harmful gases. This multi-layered structure works synergistically to purify the exhaust gas step-by-step from coarse filtration to fine adsorption, improving purification efficiency and depth, and ensuring that emissions meet clean standards. All components are securely fixed and adapted to the exhaust gas treatment process, enhancing the purification effect and environmental safety of the device.

[0014] As a further description of the above technical solution: The disassembly and assembly mechanism includes a drain pipe, which is externally and fixedly connected to the rear side of the reaction chamber. A connecting pipe is fixedly connected to the bottom external end of the drain pipe. Mounting brackets are fixedly connected to the left and right sides of the connecting pipe. A connecting shaft is rotatably connected inside the mounting bracket. A rotating plate is rotatably connected to the outside of the connecting shaft. A positioning rod is fixedly connected to the top external end of the rotating plate. Multiple mounting springs are fixedly connected to the bottom external end of the rotating plate.

[0015] The above solution involves a drain pipe connecting to a connector in the assembly / disassembly mechanism. A rotating clamp plate rotates around the connecting shaft of the mounting frame, and a positioning lever, in conjunction with a mounting spring, can quickly lock or release the connection structure. This facilitates rapid assembly / disassembly of the drain pipe and connector, while the spring provides stable elasticity to ensure a sealed connection. Operation is convenient and labor-saving, improving maintenance and cleaning efficiency, and enhancing the flexibility and reliability of the device's assembly / disassembly.

[0016] As a further description of the above technical solution: The external rotating plate is rotatably connected to the inside of the mounting bracket, and the external positioning rod is locked to the external drain pipe.

[0017] The above solution allows the rotating plate to swivel freely within the mounting bracket, causing the positioning lever to clamp tightly against the outside of the drain pipe. The installation spring enhances stability. This clamping structure is robust and reliable, preventing loosening or leakage between the drain pipe and the connecting pipe, ensuring smooth drainage. The rotating operation is convenient, improving the efficiency of disassembly, assembly, and maintenance.

[0018] As a further description of the above technical solution: The sealing plate is externally slidably connected to the inside of the connecting housing, and the sliding rod is externally slidably connected to the outside of the placement housing.

[0019] The above solution involves the sealing plate sliding inside the connecting housing, while the sliding rod slides along the outside of the housing, forming a stable sealing structure in conjunction with the return spring. Smooth sliding ensures a tight fit between the sealing plate and the sealing ring, enhancing backflow prevention and preventing external airflow from contaminating the reaction chamber. The stable, uninterrupted sliding structure improves backflow prevention reliability and device sealing.

[0020] As a further description of the above technical solution: One end of the reset spring is fixedly connected to the outside of the housing, and the other end of the reset spring is fixedly connected to the outside of the sealing plate.

[0021] The above solution involves fixing the housing and sealing plate at both ends of the return spring. The spring force continuously pushes the sealing plate to adhere to the sealing ring. When exhaust gas is emitted, the spring is compressed to ensure airflow. When there is no airflow, the spring rebounds, causing the sealing plate to seal tightly, effectively preventing backflow of external airflow. The spring force is stable and durable, ensuring a reliable seal and a clean environment inside the reaction chamber.

[0022] This utility model has the following beneficial effects: 1. In this utility model, the negative pressure fan draws the exhaust gas from the reaction chamber into the mounting housing. The gas undergoes multi-layer purification, from coarse to fine, through a sponge plate, a perforated filter plate, and an activated carbon adsorption plate. The purified exhaust gas compresses the sealing plate, causing the sliding rod to compress the reset spring and discharge. When there is no airflow, the spring rebounds to prevent backflow. The pull plate facilitates the replacement of the purification components. The purification is highly efficient and thorough, with reliable backflow prevention, convenient maintenance, and improved environmental friendliness and safety of the device.

[0023] 2. In this utility model, pressing and rotating the clamping plate squeezes the installation spring, which drives the positioning clamping rod to move outward and insert into the connecting pipe. After releasing, the spring rebounds, causing the clamping rod to lock tightly with the drain pipe groove to complete the connection. The operation is convenient and labor-saving. The spring force ensures a tight and stable clamping, preventing loosening and leakage during drainage, improving the efficiency and sealing of pipe connection, facilitating quick disassembly and maintenance, and enhancing the reliability of the device's drainage connection.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1 to 3 This utility model provides an embodiment of an irradiator reactant discharge device with a purification structure, including an outer shell 1. The outer shell 1 not only provides physical protection for internal components, isolating radiation and harmful substances from leakage, but also guides the reactants to be discharged along a preset path through a closed structure, ensuring operational safety. Support frames 2 are fixedly connected to the four corners inside the outer shell 1. The function of the support frames 2 is to bear the weight of the load-bearing frame 3 and the upper structure, evenly distributing the load to the outer shell 1, enhancing the stability of the overall structure, and preventing the device from deforming due to excessive weight of the reaction chamber 4. The load-bearing frame 3 is fixedly connected to the outside of the support frame 2. The load-bearing frame 3 serves as the direct mounting carrier for the reaction chamber 4, providing a stable support surface for the reaction chamber 4, ensuring that the reaction chamber 4 remains horizontal and stable during operation, and avoiding the impact of shaking on the reaction effect. The reaction chamber 4 is fixedly connected to the top of the load-bearing frame 3. The reaction chamber 4 is the place where the reactants undergo chemical reactions. Its sealed structure can prevent reactant leakage and at the same time provide a stable environment for the reaction, making it easy to control the reaction conditions. Specifically, the outer shell 1 isolates radiation and harmful substances from leakage, and guides reactants to be discharged along a preset path to ensure safety; the support frame 2 distributes the load to enhance overall stability and prevent device deformation; the load-bearing frame 3 provides stable support for the reaction chamber 4 to ensure its horizontal stability; the reaction chamber 4 has a sealed structure to prevent leakage, provides a stable reaction environment, facilitates control of conditions, and improves the overall safety and reliability of the device and the reaction.

[0028] A tail gas emission backflow prevention mechanism 5 is fixedly connected to the top of the reaction chamber 4. A disassembly mechanism 6 is fixedly connected to the rear exterior of the reaction chamber 4. The disassembly mechanism 6 includes a drain pipe 61. The function of the drain pipe 61 is to discharge the liquid reactants or washing wastewater generated in the reaction chamber 4. Its pipe diameter is designed according to the discharge volume to ensure discharge efficiency. The drain pipe 61 is fixedly connected to the rear exterior of the reaction chamber 4. A connecting pipe 62 is fixedly connected to the bottom exterior of the drain pipe 61. The port of the connecting pipe 62 is machined with a sealing surface to ensure connection with the external pipeline. 51. To ensure a tight seal during connection and prevent reactant leakage, mounting brackets 63 are fixedly connected to the left and right sides of the external side of the connecting pipe 62. The mounting brackets 63 are parallel to the flange face of the connecting pipe 62. The mounting brackets 63 provide mounting supports for the connecting shaft 64 and the rotating clamping plate 65, and are the basic structure for realizing the quick assembly and disassembly of the pipe 51. The connecting shaft 64 is rotatably connected inside the mounting bracket 63. The connecting shaft 64 provides the rotation center of the rotating clamping plate 65, allowing the rotating clamping plate 65 to rotate freely around it, thereby realizing the opening and closing action of the positioning clamping rod 66. Specifically, the drain pipe 61 in the disassembly and assembly mechanism 6 efficiently discharges liquid reactants and wastewater; the sealing surface of the connecting pipe 62 ensures a tight seal to prevent leakage; the mounting bracket 63 provides a fulcrum for the connecting shaft 64 and the rotating clamping plate 65, and the connecting shaft 64 supports the rotating clamping plate 65 to rotate freely to realize the opening and closing of the positioning clamping rod 66, which helps the pipe 51 to be quickly disassembled and assembled, improving discharge efficiency and operational safety and convenience.

[0029] A rotating clamping plate 65 is rotatably connected to the outside of the connecting shaft 64. The rotating clamping plate 65 rotates to drive the positioning clamping rod 66 to engage or disengage with the groove of the external pipe 51. The positioning clamping rod 66 is fixedly connected to the top of the rotating clamping plate 65. When the rotating clamping plate 65 rotates to the closed position, the positioning clamping rod 66 will engage in the groove of the flange of the external pipe 51, tightly locking the connecting pipe 62 and the external pipe 51 to prevent loosening and leakage. Multiple mounting springs 67 are fixedly connected to the bottom of the rotating clamping plate 65. The mounting springs 67 are in the extended state in their natural state, applying an upward pulling force to the rotating clamping plate 65, so that the positioning clamping rod 66 always remains in the clamped state with the groove of the external pipe 51, ensuring reliable connection. Specifically, the rotating plate 65 rotates around the connecting shaft 64, causing the positioning rod 66 to engage or disengage with the slot of the external pipe 51; when closed, the positioning rod 66 engages with the slot, tightly locking the connecting pipe 62 and the external pipe 51 to prevent loosening and leakage; the installed spring 67 extends naturally to apply tension, so that the positioning rod 66 is always locked in the slot, ensuring reliable connection and improving the ease of disassembly and assembly and sealing of the pipe 51.

[0030] Reference Figures 2 to 4 The exhaust gas backflow prevention mechanism 5 includes a mounting housing 53, which provides a closed installation space for the exhaust gas purification component 54 and guides the exhaust gas to flow through each purification component along a preset path. The exterior of the mounting housing 53 is fixedly connected to the exterior of the reaction chamber 4. The exhaust gas purification component 54 is installed inside the mounting housing 53. An exhaust pipe 57 is fixedly connected to the rear exterior of the mounting housing 53. The function of the exhaust pipe 57 is to discharge the purified exhaust gas. Its pipe diameter is adapted to the mounting housing 53 to ensure smooth airflow. A connecting housing 58 is fixedly connected to the top of the exhaust pipe 57. The connecting housing 58 provides installation space for the backflow prevention component and is the structural basis for realizing the backflow prevention function. A cross-shaped placement plate 59 is fixedly connected to the top interior of the connecting housing 58. The function of the cross-shaped placement plate 59 is to fix and support the placement housing 510 to ensure backflow prevention. The flow component is stably positioned within the connecting housing 58 without obstructing the flow of exhaust gas. The bottom of the cross-shaped placement plate 59 is fixedly connected to the placement housing 510. The placement housing 510 provides guidance and installation space for the sliding rod 511 and the return spring 512, ensuring the stable operation of the anti-backflow component. The sliding rod 511 is slidably connected to the outer bottom end of the placement housing 510. The sliding rod 511 can slide up and down along the axial direction of the placement housing 510, driving the sealing plate 513 to open and close the exhaust pipe 57. The outside of the sliding rod 511 is fitted with a return spring 512. The return spring 512 applies a downward thrust to the sealing plate 513, so that the sealing plate 513 tightly fits the sealing ring 55 when there is no airflow, blocking the reverse flow of gas. When the exhaust gas flows in the forward direction, the air pressure overcomes the spring force and pushes the sealing plate 513 upward, allowing the exhaust gas to pass through. Specifically, in the exhaust gas backflow prevention mechanism 5, the housing 53 guides the exhaust gas through the purification component for purification, and the exhaust pipe 57 discharges the clean exhaust gas; the cross-shaped placement plate 59 inside the connecting housing 58 fixes the housing 510, and the sliding rod 511 drives the sealing plate 513 to open and close; the return spring 512 pushes the sealing plate 513 to fit the sealing ring 55 to prevent backflow, and when the exhaust gas flows in the forward direction, it pushes open the sealing plate 513 to pass through, ensuring smooth purification and reliable backflow prevention.

[0031] A pipe 51 is fixedly connected to the top of the reaction chamber 4. The function of the pipe 51 is to guide the exhaust gas generated in the reaction chamber 4 to the negative pressure fan 52, providing a channel for the exhaust gas flow. Its inner wall is smooth to reduce airflow resistance. The negative pressure fan 52 is fixedly connected to the outside of the pipe 51. The negative pressure fan 52 provides power for exhaust gas discharge. By generating negative pressure, it draws out the exhaust gas in the reaction chamber 4 and forces it into the mounting housing 53, ensuring that the exhaust gas flows through the purification components and the exhaust pipe 57 in sequence, thereby improving purification efficiency. The outside of the mounting housing 53 is fixedly connected to the output end of the negative pressure fan 52. A sealing plate 513 is fixedly connected to the outside of the sliding rod 511. The sealing plate 513 acts as a return spring 512. The sealing plate 513 is fitted with the sealing ring 55 to form a sealed structure. When the exhaust gas passes through, the sealing plate 513 is lifted and the exhaust gas flows through its edge to achieve a one-way flow function. The sealing ring 55 is fixedly connected to the bottom of the outer side of the connecting housing 58. The surface of the sealing ring 55 is smooth and elastic. It fits tightly with the sealing layer of the sealing plate 513 to enhance the backflow prevention and effectively prevent external gas from flowing back into the reaction chamber 4. The outer side of the sealing ring 55 fits with the outer side of the sealing plate 513. The outer side of the housing 53 is slidably connected with the pull plate 56. The pull plate 56 makes it easy for the operator to pull out or push in the exhaust gas purification component 54, so as to realize the quick replacement or cleaning of the purification material and improve the convenience of maintenance. Specifically, pipe 51 guides the exhaust gas to negative pressure fan 52. The fan generates negative pressure to push the exhaust gas through the purification components inside the housing 53. The sealing plate 513 cooperates with the sealing ring 55, and the return spring 512 helps to prevent backflow. When the exhaust gas passes through, it opens the conduction. The pull plate 56 facilitates the replacement of the purification components. The sealing ring 55 increases the sealing performance to prevent external gas backflow, thus improving the overall exhaust gas purification efficiency, backflow prevention reliability, and maintenance convenience.

[0032] The exhaust gas purification component 54 includes a dust filter 541, which serves as the primary filter component. It can intercept larger dust particles, flocculent matter, and other impurities in the exhaust gas, preventing them from clogging subsequent filter materials. The dust filter 541 is externally fixedly connected to the inside of the mounting housing 53. A sponge plate 542 is fixedly connected to the front inside the mounting housing 53. The sponge plate 542 has good adsorption and elasticity, which can further adsorb fine particles and droplets in the exhaust gas. At the same time, it plays a buffering role in the airflow, making the airflow distribution more uniform. A perforated filter plate 543 is fixedly connected to the inside of the mounting housing 53. The perforated filter plate 543 filters residual small solid particles through physical sieving. At the same time, it guides the airflow to flow smoothly using regular perforations. An activated carbon adsorption plate 544 is fixedly connected to the rear inside the mounting housing 53. The activated carbon adsorption plate 544 efficiently captures harmful gas molecules in the exhaust gas through physical adsorption, firmly adsorbing toxic and harmful components in the pores of the activated carbon, ultimately making the purified exhaust gas meet the emission standards. Specifically, in the exhaust gas purification component 54, the dust filter 541 intercepts large particulate impurities, the sponge plate 542 adsorbs fine particles and droplets and evens the flow, the perforated filter plate 543 sieves micro-particles and guides the airflow, and the activated carbon adsorption plate 544 adsorbs harmful gases. The four-stage purification process filters the exhaust gas in a highly efficient manner to meet emission standards, prevents clogging and optimizes airflow, and improves the purification effect and reliability.

[0033] Reference Figures 4 to 6 The rotating plate 65 is externally rotatably connected to the inside of the mounting bracket 63, allowing the rotating plate 65 to freely switch between open and closed states. When closed, it drives the positioning rod 66 to lock the pipe 51. When open, it facilitates the separation of the connecting pipe 62 from the external pipe 51. The external of the positioning rod 66 is locked to the external of the drain pipe 61. The external of the sealing plate 513 is slidably connected to the inside of the connecting housing 58, and the external of the sliding rod 511 is slidably connected to the outside of the housing 510, allowing the sealing plate 513 to move flexibly under the action of the exhaust gas thrust and the elastic force of the return spring 512. When the exhaust gas is exhausted, the channel is opened by the lifting mechanism. When there is no exhaust gas, the sealing ring 55 is tightly sealed to block backflow. At the same time, the inner wall of the housing 58 provides a guide for the sealing plate 513 to ensure accurate sealing position. One end of the return spring 512 is fixedly connected to the outside of the housing 510, and the other end of the return spring 512 is fixedly connected to the outside of the sealing plate 513. When the exhaust gas passes through, the return spring 512 is compressed to store elastic potential energy. After the exhaust gas stops, it quickly pushes the sealing plate 513 to reset, ensuring the immediate response of the backflow prevention function and effectively preventing external air or impurities from entering the reaction chamber 4 in reverse. Specifically, the rotating plate 65 can be opened and closed freely. When closed, the positioning lever 66 locks the pipe 51, and opening it facilitates separation. The sealing plate 513 moves flexibly under the thrust of the exhaust gas and the return spring 512. It opens when the gas is flowing and closes to the sealing ring 55 to prevent backflow when there is no gas. The spring is compressed and stores energy, and quickly resets after the gas stops to prevent external air impurities from entering. This improves the ease of disassembly and assembly of the pipe 51, as well as the immediacy of backflow prevention and sealing.

[0034] Working principle: When exhaust gas is discharged, the negative pressure fan 52 is activated, which draws the exhaust gas from inside the reaction chamber 4 into the inside of the pipe 51. Then, it can enter the inside of the mounting shell 53 through the pipe 51. The exhaust gas can be initially purified and reduced in load by the sponge plate 542, which uses its porous adsorption to intercept larger particles and droplets. The through-hole filter plate 543 filters fine particles with its dense through holes and guides the airflow to be evenly distributed. The activated carbon adsorption plate 544 adsorbs harmful gas molecules with its high specific surface area. The three layers, from coarse to fine and from physical to chemical adsorption, can purify the exhaust gas. The purified exhaust gas can compress the sealing plate 513, which in turn compresses the sliding rod 511, allowing the sliding rod 511 to slide inside the housing 510. This causes the return spring 512 outside the sliding rod 511 to deform, allowing the exhaust gas to enter the exhaust pipe 57 through the cross-shaped placement plate 59 and then be discharged outside the device, thus preventing backflow of the exhaust gas. By pulling the pull plate 56, the sponge plate 542, the perforated filter plate 543, and the activated carbon adsorption plate 544 inside the housing 53 can be removed and replaced. When connecting the drain pipe 61 and draining water outward, pressing the rotating plate 65 causes it to compress the mounting spring 67, which in turn causes the positioning rod 66 to move outward. By inserting the connecting pipe 62 into the outside of the drain pipe 61, releasing the rotating plate 65 causes the mounting spring 67 to spring back, which in turn causes the rotating plate 65 to engage with the positioning rod 66 in the groove outside the drain pipe 61, thus achieving the connection of the external pipe 51 of the drain pipe 61.
