[0002] In nuclear industry production, solid wastes such as paper, cotton fabrics, and plastics will be generated. These wastes need to be stored in special containers. At the same time, the amount of these wastes is large, and many containers are needed to store them, which takes up a lot of space and causes great waste. Utility Model Content

[0003] The main purpose of the utility model is to provide a compression mechanism for nuclear industry waste, which can effectively solve the problems in the background technology.

[0005] Preferably, the bottom of the pressure head is a slightly raised spherical surface.

[0006] Preferably, a plurality of guide rods are installed on the upper portion of the pressure head, the outer periphery of the guide rods is slidably connected to the inside of the guide seat, and the guide seat is fixedly installed on the top of the bracket.

[0007] Preferably, an air collecting hood is slidably connected to the outer periphery of the guide rod, the air collecting hood is arranged on the upper part of the pressure head, the air collecting hood is connected to the exhaust filter assembly through a pipe, and the exhaust filter assembly is installed on the rear side of the upper part of the bracket.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] 1. Fill the steel drum with waste and place it on the base support. The pressure head and the gas hood descend under the action of the lifting mechanism. When the gas hood falls on the steel drum, the gas hood stops descending, the pressure head continues to descend, and begins to compress the solid waste in the steel drum. The gas collected by the gas hood during the compression process is filtered through the exhaust filter assembly and then discharged into the atmosphere or discharged to a designated location through an air pipe. When the pressure head is pressed down to the set position, the lifting mechanism drives the pressure head to rise. When the pressure head rises to the top of the steel drum, it will drive the gas hood to rise together. Until the pressure head and the gas hood rise to the set position at the top of this mechanism, the lifting mechanism stops moving, and then the steel drum is taken out of this mechanism and filled with solid waste again. The above actions are repeated until the number of repetitions reaches the set value, effectively increasing the storage capacity of the steel drum. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] like Figure 1-5As shown, a compression mechanism for nuclear industrial waste includes a bracket 1, which provides structural support for the entire mechanism and carries the entire mechanism. A lifting mechanism 7 is provided in the middle of the upper side of the bracket 1. The main function of the lifting mechanism 7 is to provide power for the up and down lifting of the pressure head 4 and the gas collecting cover 5, as well as for compressing the waste. The lifting mechanism 7 is not limited to a type and can be electric, pneumatic, hydraulic or other methods, depending on the usage. A pressure head 4 is provided at the output end of the lower side of the lifting mechanism 7. The outer periphery of the pressure head 4 is arranged inside a steel barrel 3. The main function of the steel barrel 3 is to hold solid waste, and the waste will be compressed in the steel barrel 3. The bottom of the steel barrel 3 is placed on the upper part of the base support 2. The main function of the base support 2 is to carry and limit the steel barrel 3. The lower part of the seat support 2 is set at the bottom of the bracket 1. In summary, the steel barrel 3 is filled with waste, and then the steel barrel 3 is placed on the base support 2. The pressure head 4 and the gas collecting hood 5 descend under the action of the lifting mechanism 7. When the gas collecting hood 5 falls on the steel barrel 3, the gas collecting hood 5 no longer descends, the pressure head 4 continues to descend, and begins to compress the solid waste in the steel barrel 3. When the pressure head 4 is pressed down to the set position, the lifting mechanism 7 drives the pressure head 4 to rise. When the pressure head 4 rises to the top of the steel barrel 3, it will drive the gas collecting hood 5 to rise together. Until the pressure head 4 and the gas collecting hood 5 rise to the set position at the top of this mechanism, the lifting mechanism 7 stops moving, and then the steel barrel 3 is taken out of this mechanism and filled with solid waste again. The above actions are repeated until the number of repetitions reaches the set value.

[0019] The bottom of the pressure head 4 is a slightly raised spherical surface. The main function of the pressure head 4 is to compress the waste in the steel barrel 3 under the power provided by the lifting mechanism 7. The bottom of the pressure head 4 is a slightly raised spherical surface, which can increase the contact area with the waste in the barrel, making the compression more dense and uniform. A plurality of guide rods 6 are installed on the upper part of the pressure head 4. The outer periphery of the guide rod 6 is slidably connected to the inside of the guide seat 9. The guide seat 9 is fixedly installed on the top of the bracket 1. The main function of the guide rod 6 is to provide guidance and support for the pressure head 4 and the air collecting hood 5 during the up and down lifting process, so that the two components do not deflect and hold back. The outer periphery of the guide rod 6 is slidably connected to the air collecting hood 5. The air collecting hood 5 is arranged on the upper part of the pressure head 4. The air collecting hood 5 is connected to the exhaust filter assembly 8 through a pipeline. The exhaust filter assembly 8 is installed on the upper rear side of the bracket 1. The main function of the gas hood 5 is to collect the gas squeezed out during the waste compression process. The gas contains trace amounts of harmful substances and cannot be discharged into the atmosphere at will. The gas hood 5 will be made according to the size of the steel drum 3. During the waste compression process, it will be buckled on the steel drum 3, and the top of the steel drum 3 will not be in direct contact with the atmosphere. The main function of the exhaust filter assembly 8 is to filter the gas collected by the gas hood 5 during the compression process, and then discharge it into the atmosphere, or discharge it to a designated location through an air pipe. An accordion hood is provided on the upper end of the gas hood 5, and the upper end of the accordion hood is provided on the inner top wall of the bracket 1. The accordion hood is sleeved on the outer periphery of the lower part of the lifting mechanism 7 to prevent exhaust gas from leaking from the upper part of the gas hood 5.

[0020] Working principle:

[0021] Fill the steel barrel 3 with waste, then place the steel barrel 3 on the base support 2. The pressure head 4 and the gas collecting hood 5 descend under the action of the lifting mechanism 7. When the gas collecting hood 5 falls on the steel barrel 3, the gas collecting hood 5 no longer descends, the pressure head 4 continues to descend, and begins to compress the solid waste in the steel barrel 3. When the pressure head 4 is pressed down to the set position, the lifting mechanism 7 drives the pressure head 4 to rise. When the pressure head 4 rises to the top of the steel barrel 3, it will drive the gas collecting hood 5 to rise together. Until the pressure head 4 and the gas collecting hood 5 rise to the set position at the top of this mechanism, the lifting mechanism 7 stops moving, and then the steel barrel 3 is taken out of this mechanism and filled with solid waste again. The above actions are repeated until the number of repetitions reaches the set value.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
