Description

Technical Field

[0001] The invention relates to the technical field of disinfection for veterinary drug production, in particular to a disinfection device for veterinary drug production with an internal self-cleaning function. Background Art

[0002] Veterinary drugs generally refer to drugs used to prevent, treat and diagnose animal diseases and regulate their physiological functions. During the production process, the preparation equipment needs to be disinfected regularly to prevent cross contamination and affect the safety of veterinary drug production.

[0003] Veterinary drug production typically requires the use of reactors to react or mix components, placing high demands on the safety of the equipment itself. Failure to properly disinfect the equipment can significantly impact the quality of the drug, even causing batch rejection. Currently, physical or chemical disinfection methods are used, but these methods can produce drug residues to some extent, impacting production quality.

[0004] In addition, veterinary drug production involves the cross-use of solids and liquids, and residual impurities easily adhere to the inner wall of the reactor, making it impossible to perform targeted cleaning based on the residues, affecting the overall disinfection quality. Summary of the Invention

[0005] The purpose of the present invention is to provide a veterinary drug production disinfection device with an internal self-cleaning function to solve the problems raised in the prior art.

The guiding device is used to perform fixed-point cleaning on the inner cavity of the reactor.

[0007] The inner cavity of the reactor is disinfected at high temperature by the disinfection device. The supporting device serves as the main supporting base for installing the flow guide device. The driving device serves as the main power source for driving the supporting device to operate, thereby cleaning the inner cavity of the reactor in all directions. High-temperature steam is introduced through the flow guide device for automatic disinfection, and the inner cavity wall of the reactor is automatically cleaned according to the phase change of the steam.

[0008] Furthermore, the driving device includes a lifting motor and a slide, the lifting motor and the reactor are tightly connected, a screw is provided at the output end of the lifting motor, the screw and the reactor are rotatably connected, a threaded hole is provided on the slide, the slide is slidably connected to the inner cavity of the reactor, the screw and the threaded hole of the slide are connected, and the slide and the support device are tightly connected.

[0009] The lifting motor is fixed on the reactor and is used to output torque to drive the screw to rotate. The lower end of the screw can be rotatably connected to the reactor. The slide is threadedly connected to the screw through a threaded hole, so that when the screw rotates, it drives the slide to move in the vertical direction, thereby driving the support device to move up and down, making it convenient for the diversion device to perform omnidirectional disinfection of the inner cavity of the reactor.

[0010] Furthermore, the supporting device includes a supporting ring, a rotating ring and a rotary motor, the sliding seat and the supporting ring are tightly connected, the rotary motor and the supporting ring are tightly connected, the rotating ring is provided with an internal tooth surface, the output end of the rotary motor is provided with a gear, the rotary motor is engaged with the internal tooth surface through the gear, the supporting ring is provided with a rotating groove, the rotating ring and the rotating groove are rotatably connected, the guide device includes a nozzle and a hot air pipe, the hot air pipe and the nozzle pipeline are connected, a number of nozzles are provided, and the several nozzles are transmission-connected to the rotating ring, and the gas outlet direction of the nozzle is toward the inner wall of the reactor cavity.

[0011] The support ring is fixed to the slide, supported by a slewing groove. The slewing motor is fixed to the support ring. The output gear meshes with the inner teeth of the slewing ring's inner ring, driving the slewing ring to rotate within the slewing groove, providing omnidirectional disinfection of the reactor cavity. A hot air pipe is installed through the support ring, directing high-temperature steam to the various nozzles. As the nozzles rotate with the slewing ring, they automatically disinfect the reactor cavity walls.

[0012] Furthermore, a main airway is provided on the swivel, the hot air pipe is fastened to the support ring, the lower end of the hot air pipe is communicated with the main airway, the flow guide device further comprises a stagnation assembly, the stagnation assembly comprises a floating seat, a support platform, a support spring and an electromagnet, a plurality of stagnation grooves are provided on the support ring, a plurality of slide grooves are provided along the circumference of the swivel, two floating seats are provided in each slide groove, the lower half of the slide groove is communicated with the main airway, a through hole is provided on the floating seat, the nozzle air inlet is inserted into the through hole of the floating seat, the support spring is placed in the stagnation groove, the upper end of the support spring is fastened to the support platform, and the electromagnet is placed in the stagnation groove; Initially: the two vertically arranged floating seats are located in the chute; During adjustment: the upper floating seat is placed in the slide chute and the lower floating seat is placed in the stagnation trough.

[0013] The main airway is used for the main high-temperature steam drainage. After the high-temperature steam is introduced into the main airway through the hot air pipe, the high-temperature steam is distributed to each nozzle through a ring arrangement. The nozzle is installed through a floating seat, and the floating seat is placed in the chute. There are two floating seats in each chute. In the initial state, there are two nozzles in the chute. The lower nozzle is connected to the main airway through the through hole of the floating seat, which is used to perform high-temperature disinfection on the wall surface of the reactor cavity. When impurities are detected on the wall surface of the reactor cavity, the rotating ring is in a uniform rotation state and it is impossible to perform local targeted cleaning. By energizing the electromagnet to generate suction, the lower end of the support platform is made of ferromagnetic material. Under the action of suction, the support platform moves downward and compresses the support spring, so that the lower nozzle slides out of the chute with the floating seat and falls into the stagnation tank below, thereby performing targeted cleaning on the wall surface of the reactor cavity. At the same time, the upper nozzle is connected to the main airway during the downward movement to perform a uniform disinfection process.

[0014] Furthermore, the diversion device also includes electrode plates, and several groups of two electrode plates are provided. Several detection cavities are provided on the support ring. Two electrode plates in the same group are placed in the detection cavity to form a fixed-point circuit. The electromagnet is electrically connected to the adjacent fixed-point circuit, and the nozzle spray direction is arranged to be inclined upward.

[0015] By setting electrode sheets in the detection chamber and electrically connecting them to the positive and negative terminals of the detection power supply to form a fixed-point circuit, when impurities exist on the wall surface of the inner chamber of the reactor, the steam sprayed upward from the nozzle will be blocked, causing part of the steam to fall between the two electrode sheets below, thereby making the fixed-point circuit conductive. The more local impurities there are, the more steam is blocked, making the current of the fixed-point circuit greater. When the fixed-point circuit exceeds the limited current, that is, the impurities at this time cannot be cleaned when the rotating ring rotates at a uniform speed, the magnetic pole suction of the electromagnet is used to clean this place at a fixed point, thereby improving the self-cleaning efficiency.

[0016] Furthermore, the guide device also includes a guide plate, which is fastened to the support ring. A drainage groove is provided on the guide plate, and the opening of the drainage groove is arranged downward. The drainage groove is an arc-shaped groove, and the outer side of the drainage groove faces the wall of the reactor cavity, and the inner side of the drainage groove faces the middle of the reactor cavity.

[0017] By setting up a guide plate for drainage, when high-temperature steam disinfects the wall surface of the inner cavity of the reactor, due to the low temperature of the wall surface, the steam is prone to phase change and adheres to the wall surface. Through the inclined nozzles, the high-temperature steam is inclined to flow upward. Through the upward component force, the liquid water overcomes its own gravity and flows along the drainage groove on the guide plate, thereby separating from the inner wall of the reactor to facilitate self-cleaning. When the liquid water passes the end point of the flow stroke along the drainage groove, the liquid water separates from the drainage groove and falls directly to the bottom of the inner cavity of the reactor under the action of gravity, which is convenient for discharge.

[0018] As an optimization, a compensating flow channel is provided on the support ring, the upper end of which is connected to the main airway. A baffle is provided at the lower end of the support platform, and a side opening is set on the compensating flow channel. By setting up the compensating flow channel and the side opening, the baffle blocks the side opening in the initial state. When performing local cleaning, the support platform drives the baffle downward, and the lower nozzle moves downward to connect with the compensating flow channel, facilitating targeted cleaning.

[0019] As an optimization, the main airway opening is set upward. By setting the main airway upward, the high-temperature steam transported by the hot air pipe can be directly injected into the main airway and fed from the fixed end to the rotating end.

[0020] As an optimization, the two sides of the stagnation groove are arranged tilted. By tilting the two sides of the stagnation groove, the upper surface of the support is located at the uppermost end of the stagnation groove in the initial state to prevent movement interference.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: two floating seats are provided in each chute, and in the initial state, two nozzles are provided in the chute, and the nozzles of the lower layer are connected to the main airway through the through hole of the floating seat, so as to perform high-temperature disinfection on the wall surface of the inner cavity of the reactor; when impurities are detected on the wall surface of the inner cavity of the reactor, since the rotating ring is in a state of uniform rotation, it is impossible to perform targeted cleaning on the local area, and by energizing the electromagnet to generate suction, the lower end of the support platform is made of ferromagnetic material, and under the action of the suction force, the support platform moves downward, and the supporting spring is compressed, so that the nozzles of the lower layer slide out of the chute along with the floating seat and fall into the lower In the stagnation tank, the inner wall of the reactor is cleaned at a fixed point. At the same time, the upper nozzle is connected to the main airway during the downward movement to carry out a uniform speed disinfection process. When there are impurities on the inner wall of the reactor, the steam sprayed upward from the nozzle is blocked, causing part of the steam to fall between the two electrode sheets below, thereby making the fixed-point circuit conductive. The more local impurities, the more steam is blocked, and the larger the current of the fixed-point circuit. When the fixed-point circuit exceeds the limited current, the impurities at this time cannot be cleaned when the rotating ring rotates at a uniform speed. The magnetic pole suction of the electromagnet is used to perform fixed-point cleaning here to improve the self-cleaning efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

The guiding device 3 is used to perform fixed-point cleaning on the inner cavity of the reactor 4.

[0027] The inner cavity of the reactor 4 is disinfected at high temperature by the disinfection device. The support device 1 serves as the main supporting base for installing the guide device 3. The drive device 2 serves as the main power source for driving the support device 1 to operate, thereby performing omnidirectional cleaning of the inner cavity of the reactor 4. High-temperature steam is introduced through the guide device 3 for automatic disinfection, and the inner cavity wall of the reactor 4 is automatically cleaned according to the phase change of the steam.

[0028] Furthermore, the driving device 2 includes a lifting motor 21 and a slide 23. The lifting motor 21 is firmly connected to the reactor 4.

The slide 23 is threadedly connected to the screw 22 through a threaded hole, so that when the screw 22 rotates, it drives the slide 23 to move in the vertical direction, thereby driving the support device 1 to move up and down, making it convenient for the guide device 3 to perform omnidirectional disinfection on the inner cavity of the reactor 4.

[0030] Furthermore, the support device 1 includes a support ring 11, a rotating ring 12 and a rotary motor 13, the slide 23 and the support ring 11 are fastened together, the rotary motor 13 and the support ring 11 are fastened together, the rotating ring 12 is provided with an inner tooth surface 122, the output end of the rotary motor 13 is provided with a gear, the rotary motor 13 is engaged with the inner tooth surface 122 through the gear, the support ring 11 is provided with a rotating groove 111, the rotating ring 12 and the rotating groove 111 are rotatably connected, the guide device 3 includes a nozzle 32 and a hot air pipe 31, the hot air pipe 31 and the nozzle 32 are connected by pipeline, a plurality of nozzles 32 are provided, and the plurality of nozzles 32 are transmission-connected to the rotating ring 12, and the gas outlet direction of the nozzle 32 is toward the inner cavity wall of the reactor 4.

[0031] Support ring 11 is fixed to slide 23, rotatably supporting swivel ring 12 via swivel groove 111. Rotary motor 13 is fixed to support ring 11. The output gear meshes with the inner teeth of swivel ring 12, driving swivel ring 12 to rotate within swivel groove 111, providing omnidirectional disinfection of the interior of reactor 4. Hot air pipe 31 is mounted through support ring 11 and directs high-temperature steam to various nozzles 32. As nozzles 32 rotate with swivel ring 12, they automatically disinfect the interior walls of reactor 4.

[0032] Furthermore, a main air duct 121 is provided on the swivel 12, the hot air pipe 31 is fastened to the support ring 11, and the lower end of the hot air pipe 31 is communicated with the main air duct 121. The flow guide device 3 also includes a stagnation component 33, which includes a floating seat 331, a support platform 332, a support spring 333 and an electromagnet 334. A plurality of stagnation grooves 112 are provided on the support ring 11, and a plurality of slide grooves 123 are provided along the circumference of the swivel 12. Two floating seats 331 are provided in each slide groove 123. The lower half of the slide groove 123 is communicated with the main air duct 121. A through hole is provided on the floating seat 331. The air inlet of the nozzle 32 is inserted into the through hole of the floating seat 331. The support spring 333 is placed in the stagnation groove 112. The upper end of the support spring 333 is fastened to the support platform 332. The electromagnet 334 is placed in the stagnation groove 112. Initially: the two vertically arranged floating seats 331 are located in the chute 123; During adjustment: the upper floating seat 331 is placed in the chute 123 , and the lower floating seat 331 is placed in the stagnation tank 112 .

[0033] The main airway 121 is used for the main high-temperature steam drainage. After the high-temperature steam is introduced into the main airway 121 through the hot air pipe 31, the high-temperature steam is distributed to each nozzle 32 through a ring arrangement. The nozzle 32 is installed through a floating seat 331. The floating seat 331 is placed in the chute 123. There are two floating seats 331 in each chute 123. In the initial state, there are two nozzles 32 in the chute 123. The nozzle 32 on the lower layer is connected to the main airway 121 through the through hole of the floating seat 331, which is used for high-temperature disinfection of the inner wall of the reactor 4. When the inner wall of the reactor 4 is detected, the nozzle 32 is connected to the main airway 121 through the through hole of the floating seat 331. When there are impurities on the surface, since the rotating ring 12 is in a uniform rotation state, it is impossible to perform targeted cleaning on the local area. By energizing the electromagnet 334 to generate suction, the lower end of the support platform 332 is made of ferromagnetic material. Under the action of suction, the support platform 332 moves downward and compresses the support spring 333, so that the lower nozzle 32 slides out of the slide 123 along with the floating seat 331 and falls into the stagnation groove 112 below, thereby performing targeted cleaning on the inner cavity wall of the reactor 4. At the same time, during the downward movement of the upper nozzle 32, it is connected to the main airway 121 to perform a uniform speed disinfection process.

[0034] Furthermore, the guide device 3 also includes electrode sheets 34, and several groups of two electrode sheets 34 are provided. Several detection cavities 114 are provided on the support ring 11. Two electrode sheets 34 in the same group are placed in the detection cavity 114 to form a fixed-point circuit. The electromagnet 334 is electrically connected to the adjacent fixed-point circuit, and the nozzle 32 is arranged with the spray direction tilted upward.

[0035] By arranging an electrode sheet 34 in the detection chamber 114 and electrically connecting it to the positive and negative terminals of the detection power supply to form a fixed-point circuit, when impurities exist on the inner wall of the reactor 4, the steam sprayed upward from the nozzle 32 is blocked, causing part of the steam to fall between the two electrode sheets 34 below, thereby making the fixed-point circuit conductive. The more local impurities there are, the more steam is blocked, making the current of the fixed-point circuit greater. When the fixed-point circuit exceeds the limited current, that is, the impurities at this time cannot be cleaned when the rotating ring 12 rotates at a uniform speed, the magnetic pole suction of the electromagnet 334 is used to perform fixed-point cleaning at this location, thereby improving the self-cleaning efficiency.

[0036] Furthermore, the guide device 3 also includes a guide plate 35, which is fastened to the support ring 11. A drainage groove 351 is provided on the guide plate 35, and the drainage groove 351 is arranged with its opening downward. The drainage groove 351 is an arc-shaped groove, and the outer side of the drainage groove 351 faces the inner wall of the reactor 4, and the inner side of the drainage groove 351 faces the middle of the inner cavity of the reactor 4.

[0037] By setting up a guide plate 35 for drainage, when high-temperature steam disinfects the inner wall of the reactor 4, due to the low temperature of the wall, the steam is prone to phase change and adheres to the wall. The high-temperature steam is made to flow upward at an angle through the inclined nozzle 32. Through the upward component force, the liquid water overcomes its own gravity and flows along the drainage groove 351 on the guide plate 35, thereby separating from the inner wall of the reactor 4 to facilitate self-cleaning. When the liquid water passes the end point of the flow stroke along the drainage groove 351, the liquid water separates from the drainage groove 351 and falls directly to the bottom of the inner cavity of the reactor 4 under the action of gravity, which is convenient for discharge.

[0038] As an optimization, a compensating flow channel 113 is provided on the support ring 11. The upper end of the compensating flow channel 113 is connected to the main air channel 121. A shield 335 is provided at the lower end of the support platform 332. The compensating flow channel 113 is opened on the side. By providing the compensating flow channel 113 and the side opening, the shield 335 blocks the side opening in the initial state. When performing local cleaning, the support platform 332 drives the shield 335 downward, and the lower nozzle 32 moves downward to connect with the compensating flow channel 113, facilitating targeted cleaning.

[0039] As an optimization, the main air channel 121 is opened upward. By setting the main air channel 121 upward, the high-temperature steam transported by the hot air pipe 31 can be directly injected into the main air channel 121 and fed from the fixed end to the rotating end.

[0040] As an optimization, the two sides of the stagnation groove 112 are arranged at an angle. By slanting the two sides of the stagnation groove 112, the upper surface of the support 332 is initially located at the uppermost end of the stagnation groove 112 to prevent movement interference. When the swivel 12 is transferred to the cleaning part again, if the cleaning is completed, the floating seat 331 is reset under the force of the support spring 333, facilitating continuous cleaning.

[0041] The working principle of the present invention is as follows: two floating seats 331 are provided in each chute 123. In the initial state, two nozzles 32 are provided in the chute 123. The nozzle 32 of the lower layer is connected to the main airway 121 through the through hole of the floating seat 331, and is used to perform high-temperature disinfection on the inner wall of the reactor 4; when impurities are detected on the inner wall of the reactor 4, since the rotating ring 12 is in a uniform rotation state, it is impossible to perform targeted cleaning on a local area. By energizing the electromagnet 334 to generate suction, the lower end of the support platform 332 is made of ferromagnetic material. Under the action of the suction force, the support platform 332 moves downward and compresses the support spring 333, so that the nozzle 32 of the lower layer slides out of the chute 123 along with the floating seat 331 , and falls into the stagnation tank 112 below, thereby performing fixed-point cleaning on the inner wall of the reactor 4. At the same time, during the downward movement of the upper nozzle 32, it is connected to the main airway 121 to perform a uniform speed disinfection process; when there are impurities on the inner wall of the reactor 4, the steam sprayed upward by the nozzle 32 is blocked, causing part of the steam to fall between the two electrode sheets 34 below, thereby turning on the fixed-point circuit. The more local impurities, the more steam is blocked, which makes the current of the fixed-point circuit greater. When the fixed-point circuit exceeds the limited current, that is, the impurities at this time cannot be cleaned when the rotating ring 12 rotates at a uniform speed, and the magnetic pole suction of the electromagnet 334 is used to perform fixed-point cleaning here, thereby improving the self-cleaning efficiency.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
