DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0029] Embodiment

[0030] Refer to Figures 1-6 As shown, a municipal water purification and filtration device includes a pipeline main body 1. A filter cylinder 211 is slidably connected to the inner wall of the pipeline main body 1. A sealing layer 212 is fixed to the outer wall of the filter cylinder 211. The sealing layer 212 can be made of rubber material, which can achieve a good sealing effect. The sealing layer 212 is vertically slidably connected to the inner wall of the pipeline main body 1. A limiting mechanism for restricting the up and down movement of the filter cylinder 211 is further included. The filter cylinder 211 can be disassembled through the limiting mechanism, which is convenient for the staff to take out the filter cylinder 211 and perform maintenance on its interior. Vertical sliding blocks 214 are fixed to the inner wall of the pipeline main body 1. Sliding grooves 213 that are slidably matched with the sliding blocks 214 are formed in the outer wall of the sealing layer 212. The arrangement of the sliding grooves 213 and the sliding blocks 214 ensures the stability of the vertical movement of the filter cylinder 211.

[0031] The limiting mechanism includes a fixing plate 215, a movable rod 216, a clamping block 217, a clamping groove 218 and a hole 219. The fixing plate 215 is fixed to the inner wall of the filter cylinder 211. A hole 219 is formed inside the fixing plate 215. A movable rod 216 passes through the hole 219. A clamping block 217 is fixed to one side of the movable rod 216 away from the middle position of the pipe body 1. Clamping grooves 218 corresponding to the clamping block 217 are formed on the inner walls of the filter cylinder 211, the sealing layer 212 and the pipe body 1. By pulling the movable rod 216, the clamping block 217 can be driven to disengage from the inside of the clamping groove 218. In this way, the effect of quickly disassembling the filter cylinder 211 and the pipe body 1 can be achieved, and the whole operation is more convenient and simple. A pull plate 220 is fixed to one end of the movable rod 216 away from the clamping block 217. A spring 221 is wound around the outer wall of the movable rod 216. One end of the spring 221 is connected to the fixing plate 215 and the other end is connected to the pull plate 220. The setting of the spring 221 can play an elastic reset effect. Under the elasticity of the spring 221, the clamping block 217 can be stably inserted into the inside of the clamping groove 218, improving the stability between the pipe body 1 and the spring 221. A guiding rod 223 is fixed to the outer wall of the clamping block 217. The guiding rod 223 passes through the fixing plate 215. The setting of the guiding rod 223 ensures that the movement of the clamping block 217 is stable enough. When the spring 221 rebounds, the clamping block 217 can accurately correspond to the inside of the clamping groove 218. A baffle 222 is fixed to one end of the guiding rod 223 away from the clamping block 217. The diameter of the baffle 222 is larger than that of the guiding rod 223. The baffle 222 has a good protective effect, ensuring that the guiding rod 223 will not disengage from the inside of the fixing plate 215.

[0032] The filter cylinder 211 includes a filter plate 311, a filter cotton layer 313 and an activated carbon layer 314. The filter plate 311, the filter cotton layer 313 and the activated carbon layer 314 are sequentially fixed to the inner wall of the filter cylinder 211 from top to bottom. A number of filter holes 312 are formed inside the filter plate 311. The cross-section of the filter holes 312 is circular. The setting of a number of activated carbon layers 314 can filter the fine sand and gravel in the water to achieve a preliminary filtering effect. The filter cotton layer 313 can be non-woven filter cotton. The non-woven filter cotton is formed by needling 100% pure fibers into a highly fluffy and three-dimensional deep filter layer. Its characteristics are that the fiber structure is loose, and the high porosity increases the dirt holding capacity of impurities. It belongs to a compound interception mode, which can effectively remove solid and soft particles. Larger particle impurities are intercepted on the fiber surface, while fine particles are captured in the deep layer of the filter material, so it has a high filtering efficiency. The activated carbon layer 314 can be made of activated carbon material. The working principle of activated carbon is mainly based on its unique physical and chemical properties. It is a porous carbon-containing substance with a highly developed pore structure. These pores provide a large surface area, enabling it to come into full contact with gases (such as impurities). The pore diameter of activated carbon is mostly between 2 and 50 nm, and the surface area of each gram of activated carbon can reach 500 - 1500m 2This characteristic is the basis of all applications of activated carbon. Activated carbon has a very strong adsorption capacity and can effectively absorb harmful gases and pollutants in the air, such as formaldehyde, ammonia, benzene, etc., thereby purifying the air. In addition, the adsorption process of activated carbon also depends on the movement of molecules and the adsorption force of the surface and internal pores of activated carbon, which can adsorb the adsorbed molecules into the pores. It can achieve a better filtering effect.

[0033] Working principle: when the filter cartridge 211 needs to be installed, the filter cartridge 211 is inserted into the pipe body 1. At this time, the sliding groove 213 can correspond to the sliding block 214. Then, the pull plate 220 is pulled to drive the movable rod 216 and the block 217 to move, and the spring 221 is stretched. At this time, the spring 221 slides inside the fixed plate 215. When the filter cartridge 211 continues to be embedded in the pipe body 1, the block 217 can correspond to the slot 218. By loosening the pull plate 220, the movable rod 216 and the block 217 are driven to rebound under the elasticity of the spring 221, and the block 217 can be inserted into the slot 218, so as to achieve the purpose of installing the filter cartridge 211. Similarly, by pulling the pull plate 220, the block 217 is disengaged from the slot 218, so as to disassemble the filter cartridge 211 and replace its interior.

[0034] When filtering is required, the water inside the pipe body 1 is initially filtered through the filter plate 311 to block fine sand and gravel, and the floating matter in the water can be filtered through the filter cotton layer 313. The activated carbon layer 314 can further adsorb and process the impurities in the water to achieve a comprehensive filtering effect.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
