[0001] The utility model relates to the technical field of garbage treatment devices, in particular to a harmless treatment device for medical plastic waste. Background Art

[0002] In the modern medical industry, with the widespread provision of medical services, a large amount of medical plastic waste is generated, such as used medical equipment, packaging materials, disposable syringes, gloves, etc. If these wastes are not effectively treated, they will cause serious pollution to the environment and may cause the spread of diseases, posing a threat to public health.

[0003] Traditional methods for treating medical plastic waste mainly include landfill, incineration and physical and chemical methods. However, landfill takes up a lot of land resources, and the decomposition cycle of plastic is long, causing long-term pollution to soil and groundwater. Physical and chemical treatment methods such as pyrolysis and gasification are technically complex, with high equipment costs, high operating costs, and limited treatment capacity. Therefore, incineration is the preferred treatment method;

[0004] However, in the prior art, waste is generally placed directly into an incinerator for incineration. This method is difficult to completely burn large pieces of plastic waste due to the different shapes and sizes of the plastic waste, resulting in waste of resources and potential environmental pollution. In order to fully incinerate the waste, a long time is required, so the incineration efficiency is low. If the waste is first crushed and then placed in the incinerator for treatment, although this can solve the above problem, the crushed waste still needs to be transported by manpower or machinery, which also reduces the treatment efficiency.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1 —6. Medical plastic waste harmless treatment device, including crushing and feeding mechanism, incinerator mechanism and flue gas purification mechanism;

[0027] First, the crushing and feeding mechanism includes a crushing box 101, a crushing roller 102, a valve plate 103 and a driving motor 104. Two groups of crushing rollers 102 are rotatably connected inside the crushing box 101. A gear 105 is fixedly connected to the roller shaft of each group of crushing rollers 102. The two groups of gears 105 are meshed and connected. A conical collecting box 106 is provided at the bottom of the crushing box 101. A feeding pipe 107 is fixedly connected to the bottom of the collecting box 106. The valve plate 103 is also rotatably connected inside the feeding pipe 107. The valve plate The valve shaft 108 of 103 passes through the feed pipe 107 and is connected to the extension shaft 109 by power. The extension shaft 109 is provided with a ratchet assembly 110. The roller shaft of one group of crushing rollers 102 is connected to the extension shaft 109 by a transmission member 111, and the transmission member 111 is located at the power input end side of the ratchet assembly 110. The crushing box 101 is fixedly connected with a drive motor 104, and the drive motor 104 is connected to one group of crushing rollers 102 by power. In this way, the corresponding The crushing rollers 102 rotate, and under the action of the two sets of gears 105, the two sets of crushing rollers 102 rotate synchronously and in the opposite direction, so as to crush the medical waste. When the driving motor 104 drives the two sets of crushing rollers 102 to rotate inwardly, the transmission member 111 drives the extension shaft 109 to rotate, and under the action of the ratchet assembly 110, the valve plate 103 does not rotate. When the medical waste is crushed, the driving motor 104 can rotate in the opposite direction. At this time, the two sets of crushing rollers 102 rotate outwardly. At this time, the transmission member drives the extension shaft 109 to rotate, so that the valve plate 103 rotates, so that the valve plate 103 can open the discharge pipe 107. When the discharge pipe 107 needs to be closed, the driving motor 104 can drive the valve plate 103 to continue to rotate, so as to close the discharge pipe 107. Even if the crushing rollers 102 are crushing the medical waste, under the action of the ratchet assembly 110, the valve plate 103 will not move to close the discharge pipe 107.

[0028] Secondly, the bottom of the feed pipe 107 is fixedly connected to the incinerator mechanism. Specifically, the incinerator mechanism includes a furnace body 201, a first burner 202, and a second burner 203. A primary main combustion chamber 204 and a secondary combustion chamber 205 are arranged inside the furnace body 201. A plurality of partition plates 206 are fixedly connected in the secondary combustion chamber 205. The feed pipe 107 is fixedly connected to the furnace body 201 and corresponds to the primary main combustion chamber 204. The furnace body 201 is fixedly connected with the first burner 202 corresponding to the primary main combustion chamber 204. The furnace body 201 is fixedly connected with the second burner 203 corresponding to the secondary combustion chamber 205. A flue gas exhaust pipe 207 is fixedly connected to the corresponding secondary combustion chamber 205. When the crushed medical waste falls into the primary main combustion chamber 204, the discharge pipe 107 can be closed through the valve plate 103, so as to prevent the flue gas generated when the medical waste is burned from being discharged to the outside without being treated, causing environmental pollution. The medical waste is burned by the first burner 202, and the flue gas generated after the combustion can enter the secondary combustion chamber 205, and the partition plate 206 divides the secondary combustion chamber 205 into multiple chambers, so that the flue gas flow path can be increased, so that the flue gas is burned again by the second burner 203, thereby ensuring that the incineration treatment is thorough;

[0029] In order to achieve flue gas purification, the incinerator mechanism and the flue gas purification mechanism are connected by pipelines, specifically, the flue gas exhaust pipe 207 is connected to the flue gas purification mechanism pipeline, and the flue gas purification mechanism includes a cyclone dust collector, a gas washing tower, an activated carbon adsorber, a UV photolysis catalytic oxidation device, a deodorizing tower, and a chimney which are connected in sequence through a gas transmission pipeline, and an exhaust fan is installed on the gas transmission pipeline, so that the exhaust fan discharges the flue gas to the outside after dust removal, washing, adsorption, catalytic oxidation, and deodorization treatment in sequence, thereby reducing particulate matter, harmful gases and odors in the flue gas and protecting the environment, and also includes an outer container 301, and the cyclone dust collector, gas washing tower, activated carbon adsorber, UV photolysis catalytic oxidation device, and deodorizing tower are all located in the outer container 301, which can avoid direct exposure to the outside world and reduce the service life of the equipment.

[0030] The utility model is further optimized. To ensure the stability of the valve plate 103 after rotation, a worm gear 112 is fixedly connected to the valve shaft 108, a frame 113 is fixedly connected to the discharge pipe 107, a worm 114 is rotatably connected to the frame 113, the worm 114 is meshingly connected to the worm wheel 112, and an extension shaft 109 is fixedly connected to the worm 114. In this way, the stability of the valve plate 103 after rotation can be ensured by the self-locking effect of the worm 114 and the worm wheel 112, that is, it is prevented that the valve plate 103 is pushed to rotate when the waste falls, resulting in a reduction in the discharge space of the discharge pipe 107.

[0031] The utility model further states that the transmission member 111 includes a driving sprocket 115, a driven sprocket 116 and a chain 117. The driving sprocket 115 is fixedly connected to the roller shaft, and the driven sprocket 116 is fixedly connected to the extension shaft 109. The driven sprocket 116 is located on the power input side of the ratchet assembly 110, and the driven sprocket 116 is connected to the driving sprocket 115 through the chain 117.
