Abstract
Description
Technical Field
[0001] This utility model relates to the field of incinerator technology, specifically to an incinerator for medical waste. Background Technology
[0002] Medical waste includes medical swabs, syringes, medicine packaging, used medications, and patient excrement. If this waste is discharged directly without treatment, it will cause serious harm to the environment and human health. Therefore, medical waste incinerators completely incinerate medical waste through high-temperature combustion, converting harmful substances into harmless ones, achieving the goal of harmless treatment. In the incineration process, a specific type of incinerator for medical waste is essential. Incinerators are commonly used for the harmless treatment of medical and domestic waste, as well as animal waste. Their principle is to utilize the combustion of fuels such as coal, oil, or gas to carbonize the waste at high temperatures, achieving disinfection.
[0003] However, most incinerators cannot effectively purify and discharge the harmful waste generated during incineration, resulting in the production of a large amount of gases that are harmful to human health and nature during the incineration process. This makes the incineration process harmful to the environment. In addition, due to the vibration generated by the blower during the incineration process, most incinerators shake and are not stable enough, which affects the distribution of waste in the furnace and the pyrolysis efficiency.

[0015] 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.
[0016] Example: Figure 1-3As shown, this utility model provides an incinerator for medical waste, including a first combustion chamber 1, a second combustion chamber 2 fixedly installed at the top of the first combustion chamber 1, a filter device 3 fixedly connected to the top of the second combustion chamber 2, a chimney 4 fixedly installed at the top of the filter device 3, a burner 5 fixedly installed at one end of the second combustion chamber 2, and one end of the burner 5 communicating with one end of the second combustion chamber 2, a blower 12 fixedly installed at one end of the first combustion chamber 1, and one end of the blower 12 communicating with one end of the first combustion chamber 1, and four shock-absorbing mechanisms 6 fixedly connected to the bottom of the first combustion chamber 1. The shock-absorbing mechanism 6 includes a base 61, two first U-shaped plates 62 fixedly connected to the top of the base 61, and second U-shaped plates 63 slidably connected to the outer surfaces of the two first U-shaped plates 62. The tops of the two second U-shaped plates 63 are jointly fixedly connected to a top plate 64, and the middle outer surface of the top plate 64 is... A threaded rod 67 is threaded through the first combustion chamber 1. A fixing ring 66 is fixedly connected to the top of the threaded rod 67. A spring shock absorber 65 is fixedly connected to the middle of the top of the base 61. The top of the spring shock absorber 65 is fixedly connected to the bottom of the fixing ring 66. The operator can incinerate the waste twice through the first combustion chamber 1 and the second combustion chamber 2. The gas after combustion in the first combustion chamber 1 is purified by combustion of harmful gases again in the second combustion chamber 2, and then discharged through the filter device 3. During operation, the four shock-absorbing mechanisms 6 at the bottom of the first combustion chamber 1 can absorb vibration. The spring shock absorber 65 in the shock-absorbing mechanism 6 helps the first combustion chamber 1 absorb and release the vibration force during the vibration and pressure process by the two second U-shaped plates 63 sliding vertically between the inner walls of the two spring shock absorbers 65, thereby achieving the shock absorption effect.
[0017] The filter device 3 includes a housing 31. An air inlet 30 is provided at the bottom of the housing 31, and an air outlet 32 is provided at the top of the housing 31. Three fixing brackets 33 are fixedly fastened to the inner wall of the housing 31. Paint mist filter cotton 34 is fixedly fastened between the inner walls of two of the upper fixing brackets 33. A bag filter cotton 35 is fixedly sleeved at the bottom of one of the lower fixing brackets 33. The air inlet 30 and the air outlet 32 are respectively connected to the top of the second combustion chamber 2 and the bottom of the chimney 4. By changing the direction of the inertial force of the particulate matter through the fibers of the bag filter cotton 35 and the paint mist filter cotton 34, the airflow changes direction multiple times, thereby adhering the particulate matter in the exhaust gas to the outer surface of the tortuous paint mist filter cotton 34, thus achieving the effect of filtering particulate matter.
[0018] The inner walls of both sides of the first combustion chamber 1 are fixedly connected to chucks 11. The outer surfaces of the two chucks 11 are slidably fitted with slide rails 10. Multiple rectangular grooves are opened on the outer surface of the chucks 11. A furnace door 14 is rotatably connected to one side of the outer surface of the first combustion chamber 1. An observation port 15 is opened on the outer surface of the furnace door 14, and an observation mirror is fitted between the inner walls of the observation port 15. A heat insulation cotton 13 for use with the furnace door 14 is fixedly connected to one end of the first combustion chamber 1. The function of the chucks 11 is to facilitate the air circulation of the waste being incinerated through the rectangular grooves opened on the surface of the chucks 11, thereby improving the pyrolysis efficiency and preventing the waste from settling and accumulating at the bottom. The two slide rails 10 are for the convenience of the operator to remove and clean the chucks 11 through the two slide rails 10. The furnace door 14 at one end of the first combustion chamber 1 is sealed more tightly by the use of the heat insulation cotton 13 to prevent dust from spilling out. The operator can observe the interior of the first combustion chamber 1 through the observation glass in the observation port 15.
[0019] Four damping mechanisms 6 are arranged in a rectangular array. The inner walls of the two first U-shaped plates 62 slide against the outer surfaces of the two second U-shaped plates 63 respectively. The outer surface of the threaded rod 67 is threaded with a nut, and the bottom end of the nut abuts against the outer surface of the first combustion chamber 1. One end of the first combustion chamber 1 and one end of the second combustion chamber 2 are connected by a connecting pipe. The four damping mechanisms 6 arranged in a rectangular array provide stable and balanced support for the first combustion chamber 1. The two first U-shaped plates 62 provide vertical movement guidance for the vibrating first combustion chamber 1. The nut on the outer surface of the threaded rod 67 is for the convenience of the operator to fix one side of the bottom end of the first combustion chamber 1 to the top of the top plate 64 by rotating the nut. The function of the connecting pipe is to allow air to enter the first combustion chamber 1 and the second combustion chamber 2 respectively through the blower 12.
[0020] Working principle: When waste needs to be incinerated, the waste is placed in the first combustion chamber 1, above the chuck 11. Then the furnace door 14 is closed, and the blower 12 is started. The blower 12 blows outside air into the first combustion chamber 1, so that the fuel can be fully burned, improving the combustion efficiency and turning it into combustible gas. After the waste is burned, the combustible gas enters the second combustion chamber 2. Then the burner 5 is started to heat the rising combustible gas for secondary combustion, so that the gas temperature is increased and the combustible gas is fully oxidized. Then the gas passes through the bag filter cotton 35 in the filter device 3 to filter the secondary combustion gas. The gas is filtered for the first time by the bag filter cotton 35. The filtered gas passes through the paint mist filter cotton 34 in the two fixed frames 33 to stick the particulate matter in the gas. The fibers of the paint mist filter cotton 34 change the direction of the inertial force of the particulate matter, so that the particulate matter sticks to the surface of the tortuous paint mist filter cotton 34, thereby achieving the effect of filtering particulate matter. The filtered gas greatly reduces harmful substances and is discharged from the top of the chimney 4.
[0021] When the furnace body vibrates, the first combustion chamber 1, during the vibration process, causes the top plate 64 to move the two second U-shaped plates 63 up and down between the inner walls of the two first U-shaped plates 62. The two sliding second U-shaped plates 63 help to apply the impact force of the vibration vertically downward, providing a moving guide for the vibration force. The base 61 is grounded and, through the elastic support of the spring shock absorber 65, effectively absorbs and releases the impact force brought by the furnace body, thereby reducing the vibration and impact of the first combustion chamber 1. The operator can adjust the downward pressure force of the first combustion chamber 1 on the spring shock absorber 65 by rotating the threaded rod 67.
[0022] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
