Description

Technical Field

[0001] The utility model belongs to the technical field of filter bags, in particular to a combined dust-proof filter bag. Background Art

[0002] At present, filter bags are mostly used to filter particulate matter in liquids, and the filter bags for filtering particulate matter are mostly single-structure filter bags. Filter bags with this structure are: first, more troublesome to use, and need to be hung one by one to filter out moisture in the liquid; second, after being hung, the filter bags will shake left and right when exposed to external force or wind, which can easily shake the particulate matter in the filter bags out of the filter bags; third, the dust-proof effect is poor. Summary of the Invention

[0003] The utility model aims to provide a combined dust-proof filter bag which can filter more liquids containing particulate matter in sequence, has stable positioning and good dust-proof effect.

[0004] The purpose of this utility model is to solve:

[0005] A combined dust filter bag comprises three or more pockets with upward openings arranged at intervals, the pockets comprising a left side cloth, a rear side cloth, a right side cloth and a front side cloth which are sewn sequentially with adjacent side cloths on vertical sides with sutures, the lower parts of the left side cloth, the rear side cloth, the right side cloth and the front side cloth are sealed with a bottom cloth and sutures, the periphery of the upper opening of the pocket is provided with an outer turning edge or an inner turning edge and a rod insertion channel with a ring-shaped cross section formed after sewing, and the front and rear sides of the rod insertion channel are respectively provided with one or more sockets for inserting rods.

[0006] As a further optimization of the above technical solution, the lengths of the left side fabric and the right side fabric in the front-to-back direction are greater than the lengths of the rear side fabric and the front side fabric in the left-to-right direction.

[0007] As a further optimization of the above technical solution, a group portion for positioning all pockets is sewn on the front and rear sides of the lower portion of the outer contour of all the pockets or around the outer contour.

[0008] As a further optimization of the above technical solution, two or more ropes are respectively provided on the front and rear sides of the group part.

[0009] As a further optimization of the above technical solution, one or more sheaths are provided on the outside of the socket, and the upper and lower sides of the sheaths are sewn to the upper and lower sides of the socket to facilitate the insertion of a rod through the socket.

[0010] As a further optimization of the above technical solution, one or more sheaths are provided on the outside of the socket, and the sheaths are U-shaped and wrap around the upper edge of the pocket. The two ends of the sheaths are aligned and sewn on the lower side of the socket to facilitate the insertion of a rod through the socket.

[0011] As a further optimization of the above technical solution, the dust-proof filter bag is made of filter cloth.

[0012] The outstanding advantages of the utility model compared with the prior art are:

[0013] 1. Easy to use and high filtration efficiency: A combined dust filter bag of the utility model contains multiple pockets, such as 10, 20 or more pockets. Such filter bags can filter more liquids containing particulate matter by filling them in sequence. It is easy to use and has high filtration efficiency.

[0014] 2. Stable positioning: The upper part of the utility model is suspended by a rod passing through the rod insertion channel, and the lower part is tied to a fixed object with a rope. The structure is stable and will not shake during the water filtering process. The particles contained in the liquid in the bag will not be shaken out due to external force or wind.

[0015] 3. The multiple pockets of the utility model are arranged at intervals without affecting each other, and the ventilation and filtering effects are good.

[0016] 4. Good dustproof effect: During the use of the utility model, after the liquid containing particulate matter is put into the pocket, the two rods in the rod insertion channel passing through the same pocket can be placed close to each other, which can prevent dust and foreign matter from entering the pocket and has a good dustproof effect.

[0017] 5. The utility model is suitable for filtering liquids containing particles or drying particles and / or solids. BRIEF DESCRIPTION OF THE DRAWINGS
