Technical Field

[0001] The utility model belongs to the technical field of activated carbon filling equipment for gas filter boxes used in gas masks, and specifically relates to a novel blizzard type canning device. Background Art

[0002] At present, the protective material used in anti-gas filter boxes is mainly granular activated carbon. In the past, the filling of activated carbon was mainly done manually, which wasted a lot of manpower and material resources, and the production efficiency was not high, affecting the market supply and demand of the product. In recent years, with the advancement of science and technology, automated activated carbon filling equipment has emerged, which has greatly reduced the production cycle of anti-gas filter elements. However, based on the principle of activated carbon protecting toxic gases, in order to ensure the protection time and protection efficiency of the filter box, it is necessary to ensure that the unit density of the activated carbon in the filter box is as high as possible, but the unit density cannot be too high to affect the breathing resistance of the gas mask. In addition, the selection of activated carbon particles varies according to the use environment of the gas mask. On the other hand, if the gap between the activated carbon in the filter box is too large, the vibration generated by the filter box during packaging and transportation may cause the activated carbon in the filter box to be partially dissatisfied. Therefore, it is necessary to design a device that can increase the amount of activated carbon in the filter box. Utility Model Content

[0003] The utility model aims at the above-mentioned problems, makes up for the deficiencies of the prior art, and provides a new type of blizzard type canning device; the utility model can ensure that the filling density and filling uniformity of the materials are uniform, tight, and without dead angles in both the horizontal and vertical directions, and can effectively control the powdering phenomenon caused by the collision between materials.

[0019] As shown in the accompanying drawings, this embodiment provides a new type of blizzard-type canning device, including a filling tube 1. When the device is in use, the filling tube 1 is fixedly installed on an external bracket or platform.

[0020] The processing size of the filling tube 1 is designed according to the applicable gas filter box 7. The gas filter box 7 is an important component of the self-priming filter type gas mask. After the staff wears the gas mask, the harmful gas and particles are filtered and adsorbed through the gas filter box 7 during the inhalation process to ensure that the wearer inhales safe air. The gas filter box 7 is designed according to multiple standard sizes, and the inner diameter is consistent with the inner diameter of the gas filter box 7, ensuring that the activated carbon particles falling freely from the filling tube 1 can completely fall into the gas filter box 7, and the distribution in the gas filter box 7 is more uniform and compact without dead angles, realizing blizzard-style filling.

[0021] A discharge switch groove 2 is provided on the upper side wall of the filling tube 1, and an insert plate 3 is removably inserted into the filling tube 1 from the discharge switch groove 2. The shape of the insert plate 3 inserted into the filling tube 1 matches the internal cross-section of the filling tube 1 corresponding to the discharge switch groove 2, so that after the insert plate 3 is inserted into the filling tube 1, it can completely fit with the inner wall of the filling tube 1.

[0022] The filling tube 1 forms a storage unit in the space above the plug plate 3. After the plug plate 3 is inserted, the weighed activated carbon particles are poured into the top storage unit. After the plug plate 3 is opened, the activated carbon particles fall into the filling tube 1.

[0023] The use of the top storage unit and the insert plate 3 can reduce the sliding friction caused by the contact between the activated carbon and the filling tube 1 due to the pouring angle, ensuring that the activated carbon particles tend to fall vertically into the filling tube 1 and fall freely in the filling tube 1 only under the action of gravity.

[0024] A trumpet nozzle 9 is provided at the top of the filling tube 1 to prevent the activated carbon particles from leaking out during the filling process.

[0025] The weight of activated carbon poured into the top stock unit is calculated based on the effective storage volume of activated carbon in the gas filter box 7 and the density of activated carbon particles. Taking granular coconut shell activated carbon as an example, its density is between 0.5-0.55g / cm3. Combined with the effective carbon volume of the gas filter box 7, the weight of activated carbon that can be loaded in the gas filter box 7 under normal conditions can be obtained. By using this set of equipment for filling, the total weight of activated carbon that can be loaded in the gas filter box 7 can be increased by 8%-14%. The increase effect is related to the size of the activated carbon particles. The smaller the particle size, the better the increase effect, and the larger the particle size, the lower the increase effect. The total amount of activated carbon finally injected into the top stock unit is: original total weight × (1 + increase amount %).

[0026] A partition net 4 is connected to the filling tube 1 below the discharge switch slot 2, and a plurality of ball rings 5 ​​are piled up on the partition net 4. The activated carbon particles fall into the ball rings 5, which have a certain impact on the ball rings 5. The designed partition net 4 is fixed in the filling tube 1 and has a certain load-bearing capacity, ensuring that the partition net 4 will not be deformed after being impacted and its position in the filling tube 1 remains unchanged.

[0027] The ball ring 5 is a metal ball ring, and the structure of metal ball rings on the market is a unified structure. After the activated carbon particles fall vertically from the top storage unit into the filling tube 1, the flow direction of the activated carbon particles is changed by the special structure of the ball ring 5, and finally the activated carbon particles falling into the gas filter box 7 are more dispersed, reducing the gaps between the activated carbon particles and thus increasing the density of the activated carbon particles per unit volume.

[0028] The position of the partition 4 in the filling tube 1 is set according to the size of the activated carbon particles to be used, with the goal of making the activated carbon particles injected into the gas filter box 7 more compact and more evenly distributed than the activated carbon particles falling into the gas filter box 7 by free fall. The smaller the mesh size of the activated carbon particles, the closer the partition 4 is to the bottom of the filling tube 1. Since the size of activated carbon particles is generally between 20 and 100 meshes, according to multiple tests during the design, for activated carbon particles with 20 meshes, the ball ring 5 is closer to the bottom of the filling tube 1, and the activated carbon particles that finally fall into the gas filter box 7 are more compact at 5 cm; for activated carbon particles with 100 meshes, the ball ring 5 is farther from the bottom of the filling tube 1, and the effect is best at 15 cm, so it is best to set the partition 4 at 5 cm-15 cm from the bottom of the filling tube 1.

[0029] Because the ball ring 5 is added in the filling tube 1, during the filling process of the activated carbon particles, due to the structure of the ball ring 5, a part of the activated carbon particles will remain in the ball ring 5, affecting the weight accuracy of the activated carbon finally falling into the gas filter box 7. In order to ensure the accuracy of the weight of the activated carbon filled in the gas filter box 7, a plurality of vibration devices 8 are fixed on the outer wall of the filling tube 1 at the corresponding ball ring 5 stacking position to ensure that all the particles remaining in the ball ring 5 can fall into the gas filter box 7. The vibration device 8 is a pneumatic vibrator, which is installed close to the outer wall of the filling tube 1 in combination with the circular curvature of the outer wall of the filling tube 1.

[0030] A compaction platform 6 is provided below the filling tube 1, and a gas filter box 7 is fixed on the compaction platform 6 corresponding to the bottom end of the filling tube 1. The top surface of the gas filter box 7 is close to the bottom surface of the filling tube 1. The activated carbon particles injected from the filling tube 1 by free fall are finally poured into the gas filter box 7 after the ball ring 5 changes its falling direction. After the activated carbon particles are filled into the gas filter box 7, the compaction platform 6 is used to compact the activated carbon particles in the gas filter box 7 to further reduce the gaps between the activated carbon particles, increase the density of the particles per unit volume, and complete the filling.

[0031] It can be understood that the above specific description of the utility model is only used to illustrate the utility model and is not limited to the technical solution described in the implementation mode of the utility model. Ordinary technicians in the field should understand that the utility model can still be modified or replaced by equivalents to achieve the same technical effect; as long as the use requirements are met, they are within the protection scope of the utility model.
