Description

Technical Field

[0001] The utility model relates to the technical field of incinerators, and particularly relates to a feeding sealing device. Background Art

[0002] Medical waste incineration is a harmless treatment method for medical waste. High-temperature carbonization incineration of medical waste can completely eliminate harmful bacteria and viruses in medical waste, achieving the purpose of disinfection and cleaning. The carbide generated by high-temperature incineration of medical waste can also be recycled, recycling waste and achieving environmental protection purposes.

[0003] The incineration of medical waste is carried out through a carbonization incinerator. The feeding port of the existing incinerator is open for convenient feeding. Whether there is waste entering the feeding port or not, the feeding port is always in an open state. As a result, during the process of incinerating waste in the incinerator, some waste gas is likely to leak from the feeding port, causing environmental pollution and poor influence. Content of the Utility Model

[0004] Based on the above description, the utility model provides a feeding sealing device to solve the problem of waste gas leakage easily occurring in the feeding hopper of the existing incinerator.

[0005] The technical solution of the utility model to solve the above technical problems is as follows: A feeding sealing device includes an incinerator and a feeding hopper arranged on the top of the incinerator. The inner side of the feeding hopper is provided with an inclined sealing structure. A torsion spring is installed between the sealing structure and the feeding hopper. The torsion spring drives the sealing structure and the feeding hopper to form automatic opening and closing adjustment through rotation. A material guiding port is arranged on the inner side of the feeding hopper to cooperate with the sealing structure for quick opening and closing.

[0006] On the basis of the above technical solution, the utility model can also be improved as follows.

[0007] Further, a first installation groove is opened on the left side of the inner wall of the feeding hopper, and an arc groove is opened at the top of the inner wall of the first installation groove.

[0008] Further, the material guiding port is composed of an expanded material groove. The expanded material groove is arranged on the right side of the inner wall of the feeding hopper and is located at the bottom of the arc groove. The expanded material groove is arc-shaped. The bottom of the inner wall of the expanded material groove is flat and is inclined towards the incinerator.

[0009] Further, the sealing structure is composed of a shaft rod and a sealing plate. The shaft rod is installed between the back and front of the inner wall of the feeding hopper, and the center of the circle coincides with the center of the arc groove. One end of the sealing plate is semicircular and is installed in the center on the outside of the shaft rod and fits with the inner wall of the arc groove.

[0010] Further, the other end of the sealing plate is inclined towards the expanded material tank and fits against the right side of the inner wall of the feed hopper. The right side of the sealing plate is located at the top of the expanded material tank. The front and back surfaces of the sealing plate are both in contact with the inner wall of the feed hopper. A second installation groove is formed in the center of the bottom of the sealing plate, and the second installation groove covers the shaft rod.

[0011] Further, the torsion spring is installed on the outer side of the shaft rod. One end of the torsion spring is installed at the top of the inner wall of the first installation groove, and the other end is installed on the left side of the inner wall of the second installation groove.

[0012] Compared with the prior art, the technical solution of the present application has the following beneficial technical effects:

[0013] In the present utility model, through the sealing plate and the torsion spring installed on the outer side of the shaft rod, in cooperation with the expanded material tank arranged inside the feed hopper, under normal conditions, the torsion spring supports the sealing plate to unfold through torsion force. The sealing plate is in an inclined state to seal the inside of the feed hopper. When garbage is added from the feed inlet, it will act on the sealing plate through its weight to make it rotate and unfold, forming automatic opening and closing, without affecting the normal feeding of garbage. With the opening of the expanded material tank, even when the unfolding angle of the sealing plate is relatively small, there is still a large space for garbage to pass through and be fed, enabling the garbage to quickly pass through the sealing plate and making the feed hopper close, effectively preventing the waste gas generated by incineration from leaking from the feed hopper and causing pollution.

[0019] To facilitate the understanding of the present application, the present application will be described more comprehensively below with reference to the relevant drawings. Embodiments of the present application are shown in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0021] Please refer to Figures 1-3 , a feeding sealing device of the present utility model includes an incinerator 1 and a feeding hopper 2 arranged on the top of the incinerator 1. The inner side of the feeding hopper 2 is provided with an inclined sealing structure. A torsion spring 5 is installed between the sealing structure and the feeding hopper 2. The torsion spring 5 drives the sealing structure and the feeding hopper 2 to form automatic opening and closing adjustment through rotation. A material guiding port is arranged inside the feeding hopper 2 to cooperate with the sealing structure for quick opening and closing.

[0022] Please refer to Figure 2 , a first installation groove 22 is opened on the left side of the inner wall of the feeding hopper 2. The top of the inner wall of the first installation groove 22 is provided with an arc groove 23. The setting of the arc groove 23 enables the semi-circular end of the sealing plate 4 to fit with the inner wall of the feeding hopper 2 without affecting rotation after installation, ensuring the sealing performance. The material guiding port is composed of an expanded material groove 21. The expanded material groove 21 is arranged on the right side of the inner wall of the feeding hopper 2 and is located at the bottom of the arc groove 23. The expanded material groove 21 is arc-shaped. The bottom of the inner wall of the expanded material groove 21 is arranged in a plane and is inclined towards the incinerator 1. The setting of the expanded material groove 21 enables the sealing plate 4 to generate sufficient clearance with the expanded material groove 21 for garbage to be discharged into the incinerator 1 only by rotating and unfolding a small angle. The sealing plate 4 does not need to be fully unfolded inside the feeding hopper 2, shortening the opening and closing movement angle of the sealing plate 4, enabling the sealing plate 4 to quickly close and seal the feeding hopper 2 after unfolding, and effectively preventing waste gas from leaking from the feeding hopper 2.

[0023] Please refer to Figure 2 , the sealing structure is composed of a shaft rod 3 and a sealing plate 4. The shaft rod 3 is installed between the back inner wall and the front inner wall of the feeding hopper 2, and the center of the circle coincides with the center of the arc groove 23. One end of the sealing plate 4 is semi-circular and is installed in the center on the outside of the shaft rod 3 and fits with the inner wall of the arc groove 23.

[0024] Please refer to Figure 2 , the other end of the sealing plate 4 is inclined towards the expanded material groove 21 and fits with the right side inner wall of the feeding hopper 2. The right side of the sealing plate 4 is located at the top of the expanded material groove 21. The front and back of the sealing plate 4 both fit with the inner wall of the feeding hopper 2. A second installation groove 41 is opened at the center of the bottom of the sealing plate 4. The second installation groove 41 covers the shaft rod 3. The setting of the second installation groove 41 hollowes out the bottom of the sealing plate 4, reducing the weight of the sealing plate 4, enabling the torsion force of the torsion spring 5 to better act on the movement of the sealing plate 4 and form a seal with the feeding hopper 2.

[0025] Please refer to Figure 2, the torsion spring 5 is installed outside the shaft rod 3. One end of the torsion spring 5 is installed at the top of the inner wall of the first installation groove 22, and the other end is installed at the left side of the inner wall of the second installation groove 41. The sealing plate 4 is inclined and arranged inside the feed hopper 2. The sealing plate 4 is supported by the torsion force of the torsion spring 5 to fit against the inner wall of the feed hopper 2 to form a seal. When the sealing plate 4 needs to be unfolded, a certain pressure is required to make the torsion spring 5 move. The larger the unfolding angle, the greater the pressure on the torsion spring 5. The inclined arrangement of the sealing plate 4 and the cooperation of the expanded material tank 21 reduce the angle at which the sealing plate 4 needs to be unfolded when the garbage is fed. The torsion spring 5 only needs to be twisted by a small external force, reducing the lower limit of the bearing pressure when the sealing plate 4 is driven to unfold, effectively avoiding the situation where when the single feed of garbage is relatively light, the sealing plate 4 is less stressed and cannot be fully unfolded, resulting in the garbage being stuck between the sealing plate 4 and the feed hopper 2.

It should also be understood that the terms "comprises / comprising" or "has / having" etc. specify the presence of the stated features, integers, steps, operations, components, parts or combinations thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, components, parts or combinations thereof.
