Detailed Description

The invention is described in detail below with reference to the attached drawing figures:

example one

An efficient sterilizing conveying line as shown in fig. 1, 2 and 3 comprises a support 1, a conveying line positioned on the support 1, a shell 3 covering the conveying line, and an ultraviolet irradiation device 5 positioned in the shell 3. The support in this embodiment includes a vertical frame arranged from bottom to top and a frame with a concave section, which is installed above the vertical frame and is arranged according to the extending shape of the conveying line, and the wall surface of the frame is a closed wall surface. The transfer chain has the income material section 21 and the ejection of compact section 23 that are located the level setting at its direction of delivery both ends, and 23 vertical direction positions in the ejection of compact section direction in this embodiment are higher than income material section 21 and connect through one section by the linkage segment 22 of income material section 21 to ejection of compact section 23 tilt up between the two to it kills the subject matter and forms to send into by the upper reaches on this transfer chain and rises to the level after ejection of compact section 23 to send out through linkage segment 22 after getting into material section 21. Support 1 and casing 3 enclose to close and form and hold chamber 4, and casing 3 encloses with feed section 21 and closes and form the entry 41 that holds chamber 4, and casing 3 encloses with play material section 23 and closes and form the export 42 that holds chamber 4, forms a relative closure promptly, and only entry 41 and entry 42 communicate the open-ended cavity in exterior space to through the ultraviolet ray of ultraviolet irradiation device 5 transmission and through the ozone that the interior air of ultraviolet ionization holds chamber 4 produced in this cavity to the disinfection of organic residue, bacterium, virus on the object surface of disinfection. Meanwhile, the inclined connecting section 22 is matched with the correspondingly extended shell 3 and the bracket 1 to form an inclined accommodating cavity 4 space at least above the inlet 41, so that the ozone loss to two sides of a common horizontal conveying disinfection assembly line can be reduced, and the concentration of the ozone can be ensured to have high-efficiency disinfection capability.

In this embodiment, the housing 3 extends from the end of the discharging section 23 to the rear thereof and extends downward in the end thereof, so that the outlet 42 is a baffle 43 which is open downward, the baffle 43 is provided with a ventilation pipe 44 which is communicated with the accommodating cavity 4, and the baffle 43 reduces the opening area of the housing 3 and the bracket 1 which are enclosed at the outlet 42, thereby reducing the loss of ozone generated by electric power. Meanwhile, the baffle 43 enables the opening of the outlet 42 to be downward, so that on one hand, the sent sterilizing target object is limited to fall downward, the subsequent boxing and collection are convenient, and on the other hand, the loss of ozone is further reduced. Ozone is harmful to human bodies, so that the vent pipe 44 is arranged on the baffle 43 at the tail end of the integral containing cavity 4 to guide air sent out from the containing cavity 4 towards the outlet 42 to flow out into the vent pipe 44, harm to the human bodies can be reduced by connecting the tail end of the vent pipe 44 into an ozone neutralizing device or opening an influence-free space, and influence of ozone leaking out from the outlet 42 to workers around the human bodies is avoided.

In this embodiment, a flow valve 441 and an exhaust fan 442 are disposed in the ventilation pipe 44. The ventilation pipe 44 is used at this time to send out air from the inside of the containing chamber 4 to control the ozone concentration in the containing chamber 4 (excessive concentration may cause too strong oxidation to cause degradation of the sterilizing target fabric). The connecting end of the flow control valve is lower than the height of the conveying line at the outlet 42, the exhaust fan 442 can be a common fixed-frequency direct current fan or a variable-frequency wind-force adjustable fan, as long as the flow control valve can play a role in outwards discharging air in the accommodating cavity 4, wherein the flow valve 441 is used for controlling the quantity of outwards flowing air, so that the air in the accommodating cavity 4 can slowly flow out through the flow control of the flow valve 441 by reducing or even closing the flow at the initial stage of operation of the device, the speed of generating ozone and improving the concentration is improved, the efficiency is increased, and the energy consumption is reduced; and after the operation is stable, the corresponding opening flow rate is high, and the concentration control efficiency of the exhaust fan 442 is improved.

In this embodiment, the conveyor line comprises a powered roller 24 mounted to the carriage 1 and a light-transmissive conveyor belt 25 having a mesh driven by the powered roller 24. The conveyer belt 25 adopts the grid setting for when holding the operation in chamber 4, the air that contains ozone can pass the grid and contact the one side of disinfecting the subject matter and conveyer belt 25 contact, improves the wholeness of disinfecting. Meanwhile, the conveying belt 25 is arranged in a light-transmitting mode, and the ultraviolet irradiation device 5 can be arranged below the conveying belt 25 in the vertical direction, so that the surface, contacting the conveying belt 25, of the object to be sterilized can be irradiated from the lower direction, and the sterilizing comprehensiveness is further improved.

As shown in fig. 2, in the present embodiment, the ultraviolet irradiation device 5 includes a plurality of devices respectively disposed on the top and side of the inner wall of the housing 3 and the side of the conveyor belt 25 inside the rack 1 along the extension direction of the conveyor line, so as to have an omnidirectional irradiation killing effect with respect to the object to be killed, wherein the ultraviolet irradiation device 5 disposed on the side of the conveyor belt 25 inside the rack 1 provides bottom-up irradiation killing. The ultraviolet irradiation device 5 is not arranged at the bottom of the bracket 1, because the irradiation effect is not ideal when the bracket passes through the two layers of conveyer belts 25 upwards, the energy consumption is higher than the effect.

In this embodiment, the ultraviolet irradiation device 5 is an electrodeless UV lamp tube connected with a power adjustment device. Compared with the commonly adopted polarized lamp tube, the electrodeless UV lamp tube has higher energy conversion rate and energy density, thereby realizing better killing effect with lower energy consumption and having higher ozone generation speed. Meanwhile, the intensity of ultraviolet rays emitted by the device and the speed of generating ozone can be controlled by the power adjusting device according to the requirements in actual disinfection.

In the present embodiment, the height of the ultraviolet irradiation device 5 in the vertical direction, which is provided along the extending direction of the conveyor line, is higher than the height of the top of the housing 3 at the inlet 41. Thus, a distribution pattern higher than the inlet 41 is formed in the accommodating chamber 4, because the ultraviolet irradiation device 5 first ionizes the air near its periphery to generate ozone when operating, and the concentration of ozone in the accommodating chamber 4 as a whole is gradually lowered from the near to the far side of the ultraviolet irradiation device 5, so that an approximately concentration-distributed ozone concentration distribution space in the accommodating chamber 4 is formed, and an approximately horizontal ozone concentration line (horizontal dotted line in fig. 1) and a relatively high concentration ozone space (plus sign-shaped distribution space in fig. 1) having a high-efficiency killing ability above the ozone concentration line are formed, and effective and complete killing can be achieved in the space. Meanwhile, the distribution mode of the ultraviolet irradiation device 5 enables that no high-concentration ozone exists in the area with larger exchange capacity with the outside air like the inlet 41, and no device for actively generating ozone exists, so that a large amount of ozone cannot be lost from the area, energy cannot be wasted, and the energy utilization efficiency is improved.

As shown in fig. 3, in this embodiment, the air curtain device further includes a first air curtain machine 61 and a second air curtain machine 62 which are disposed at the inlet 41, the first air curtain machine 61 is disposed on the housing 3 at the inlet 41 and points to the conveying line below, an included angle of 0 ° is formed between a plane where an air outlet of the first air curtain machine 61 is located and a vertical plane perpendicular to the conveying line, the included angle is deviated to the direction of the accommodating cavity 4, the second air curtain machine 62 is disposed on the surface of the bracket 1 below the inlet 41, and an air outlet air supply direction of the second air curtain machine is parallel to an extending direction of the connecting section 22. The downward vertical air supply through the first air curtain machine 61 can reduce the degree of outward loss of the air in the accommodating cavity 4, and can also reduce the solid impurity dust entering the accommodating cavity. The second air curtain machine 62 can reduce the downward loss of high-concentration ozone above the ozone concentration line by blowing air in the extending direction of the connecting section 22, i.e., blowing air in the direction of the ozone concentration line, so that the concentration maintaining capability is better. At the same time, the air supply thereof causes the air in the accommodating chamber 4 to present a path flowing in the conveying direction to the outlet 42, that is, the air containing ozone can be uniformly sent out from the ventilation pipe 44 along the path. The neat flow path also ensures that the contact state of the air containing ozone and the sterilization target object in the conveying process is more stable, and the sterilization effect is better.

The opening 41 in this embodiment is further provided with an adjusting plate pointing to the conveying line direction, the size of the opening 41 can be adjusted through a bolt, and the further first air curtain machine 61 and the infrared grating 7 at the opening 41 are mounted on the adjusting plate to follow up, so that the adjusting plate has good adjusting convenience.

In this embodiment, the third air curtain machine 63 is further included, and the air supply direction of the air port of the third air curtain machine 63 horizontally points to the direction of the section of the outlet 42, so that relative isolation of the inside air and the outside air at the outlet 42 is also formed, thereby further reducing the loss of ozone from the outlet 42, and further cooperating with the first air curtain machine 61 and the second air curtain machine 62, the ozone concentration above the ozone concentration line in the accommodating cavity 4 can be better maintained and controlled.

In this embodiment, the housing 3 is provided with the infrared gratings 7 which are respectively located at the outlet 42 and the inlet 41 and point to the conveying line, so that the number of the sterilizing targets entering/leaving the conveying line and the entering speed can be counted through the infrared gratings 7. The experiment shows that the number and the passing speed of the objects to be killed in the accommodating cavity 4 are different, and the required ultraviolet intensity and ozone concentration are different, so that the power adjusting device, the second air curtain machine 62, the flow valve 441, the exhaust fan 442 and the infrared grating 7 are simultaneously and electrically connected into a control device such as a computer and the like in the embodiment and are simultaneously connected with an ozone concentration sensor (not shown in the figure) and an ultraviolet intensity detection sensor which are arranged in the accommodating cavity, so that the optimal killing intensity setting is realized by regulating and controlling the operation intensity of the devices according to the corresponding relation between the number/the passing speed and the ultraviolet intensity/the ozone concentration of the objects to be killed measured in the experiment, the killing efficiency is improved, the energy consumption is optimized, and better safety monitoring and control effects are realized.

in this embodiment, still including locating first air curtain machine 61 and the second air curtain machine 62 of entry 41 department, first air curtain machine 61 locates the casing 3 of entry 41 department and points to the transfer chain of below, the 10 contained angles that the chamber 4 direction was held to the partial deviation have between the vertical plane of the wind gap air supply direction place plane of first air curtain machine 61 and the perpendicular to transfer chain, the air supply of slant transfer chain is realized at the entrance to this contained angle, and further meet certain blocking at the transfer chain surface and present the fashioned wind path of reflection to holding intracavity linkage segment 22 direction, thereby can further block the ozone that holds the chamber upper portion and run off downwards, further guarantee the ozone concentration of ozone concentration line top promptly, guarantee its concentration promptly the killing ability. Further, set up the contained angle through test on the spot many times and be 10 in this application, can control the angle of this reflection wind path and can not blow the target object (especially light gauze mask) of killing that is located on the transfer chain and cause the offset, prevent to block into the accident that influences the operation such as transfer chain, guarantee the stability of carrying the flow. Further, the reflected wind path can cooperate with the second air curtain machine 62 to enhance the control of the air flow direction in the accommodating chamber 4.
