Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of sponge processing equipment and relates to a columnar sponge netting box structure. Background Art
[0002] Sponge netting treatment is a process that removes the original mask or wall film between the foam networks to obtain a main framework network structure. It is commonly used in the processing of filter sponges. The filter sponge after netting treatment has excellent air permeability, good softness and high mechanical strength. The netting process is divided into the lye immersion method and the blasting method. The blasting method is to inject combustibles into the netting box containing sponges, and instantaneously reach a certain temperature and pressure to cause the sponge diaphragm to burst and achieve netting. At present, after the blasting is over, when the netting box is opened, the generated steam (water vapor is generated when hydrogen is used as fuel) and flue gas (waste gas generated by combustion) cannot be effectively discharged, which affects the workshop environment. Summary of the Utility Model
[0003] The purpose of the utility model is to provide a columnar sponge netting box structure for the above problems existing in the current technology. The technical problem to be solved by the utility model is how to orderly discharge the exhaust gas after netting.
[0004] The purpose of the utility model can be achieved by the following technical solutions: A columnar sponge netting box structure, characterized in that it includes a box body and a box cover. The box cover includes a main body, a cover plate and a sealing plate. An exhaust gas collection cavity is formed between the cover body and the main body. A plurality of air inlet holes are opened on the main body. A connecting rod is threadedly connected to the main body. The lower end of the connecting rod is connected to the sealing plate. The sealing plate can block all the air inlet holes. A locking nut located above the cover plate is threadedly connected to the connecting rod. The main body and the box body are detachably connected.
[0005] Further, the inner wall of the opening of the box body has a sealing inclined surface. A plurality of positioning components are arranged on the lower surface of the main body. The positioning components include an installation sleeve fixed on the main body and a positioning pin slidably connected in the installation sleeve along the radial direction of the main body. The sealing plate is located inside each positioning pin. The sealing plate has a guiding inclined surface parallel to the sealing inclined surface. Both ends of the positioning pin have a wedge-shaped part adapted to the guiding inclined surface and the sealing inclined surface. When the sealing plate blocks the air inlet holes, it can squeeze the outer end of the positioning pin below the sealing inclined surface. The main body can press the sealing surface of the opening of the box body when the positioning pin is below the sealing inclined surface.
[0006] Further, an exhaust pipe communicating with the exhaust gas collection cavity is arranged on the cover plate.
[0007] During operation, first loosen the locking nut and press the box cover. After the main body is pressed against the box body, tighten the locking nut. During the process of tightening the locking nut, the positioning pin is squeezed by the sealing plate and moves outward. During the process of the positioning pin moving outward, the main body can be driven to press against the box body, so that the sealing effect between the box body and the cover body is better. In addition, after the blasting is completed, first loosen the locking nut slightly to ensure that the positioning pin cannot be separated from the sealing inclined surface, but the sealing plate can open the air inlet, and the exhaust gas in the box body can enter the exhaust gas collection chamber from the air inlet and then be discharged. After the exhaust gas is discharged for a period of time, the locking nut can be further loosened to open the box cover. After opening the box, the netted sponge can be removed. This method not only has a good sealing effect and high pressure bearing capacity, but also can effectively open the cover after the exhaust gas is discharged, avoiding the negative impact of exhaust gas on the workshop environment.

DETAILED DESCRIPTION
[0012] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0013] like Figure 1 , Figure 2 and Figure 3 The columnar sponge mesh box structure shown includes a box body 1 and a box cover, the box cover includes a main body 21, a cover plate 22 and a sealing plate 23, an exhaust gas collecting chamber 24 is formed between the cover body and the main body 21, a plurality of air inlet holes 25 are opened on the main body 21, a connecting rod 26 is threadedly connected to the main body 21, the lower end of the connecting rod 26 is connected to the sealing plate 23, the sealing plate 23 can block all the air inlet holes 25, a locking nut 27 located on the cover plate 22 is threadedly connected to the connecting rod 26, the main body 21 and the box body 1 are detachably connected, and an exhaust pipe 4 connected to the exhaust gas collecting chamber 24 is provided on the cover plate 22.
[0014] The inner wall at the opening of the box body 1 has a sealing slope 31, and the lower surface of the main body 21 is provided with a plurality of positioning components, the positioning components include a mounting sleeve 32 fixed on the main body 21 and a positioning pin 33 slidably connected to the mounting sleeve 32 along the radial direction of the main body 21, the sealing plate 23 is located on the inner side of each positioning pin 33, the sealing plate 23 has a guide slope 34 parallel to the sealing slope 31, and the two ends of the positioning pin 33 respectively have a wedge-shaped portion 35 adapted to the guide slope 34 and the sealing slope 31, when the sealing plate 23 blocks the air inlet 25, the outer end of the positioning pin 33 can be squeezed under the sealing slope 31, and the main body 21 can press the sealing surface of the opening of the box body 1 when the positioning pin 33 is located under the sealing slope 31.
