Technical Field

[0001] This utility model relates to the field of dust filtration technology, specifically a sintered V-shaped dust removal filter unit. Background Technology

[0002] Currently, different dust removal filter materials are used in China for different working conditions to achieve the filtration effect of different media; strong acid and strong alkali working conditions have always been a major problem in the field of dust removal.

[0003] Bag filters and drum filters are commonly used. When designing a dust collector, the actual air volume to be handled must be taken into account, and the filtration area (i.e., length) of the dust collector bags and drum filters must be designed and installed.

[0004] Therefore, there are many problems, such as the difficulty in distinguishing between different types of dust collection filter media during installation; short service life; inability to withstand strong acids and alkalis; and dust collectors with dust collection bags and barrel dust collectors often occupy a large area, which makes installation, disassembly and other maintenance work extremely difficult. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a sintered V-shaped dust removal filter unit, which solves the problems of inconvenient installation, large footprint, and poor resistance to strong acids and alkalis.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sintered V-shaped dust removal filter unit, comprising several filter elements, wherein the filter elements are V-shaped, the top ends of adjacent filter elements are connected, an ABS plastic frame is provided above the filter elements, several first PP baffles are installed inside the ABS plastic frame, the connection point of a pair of adjacent filter elements is connected to the first PP baffles, a lower shell is provided on the lower side of the ABS plastic frame, and the ABS plastic frame and the filter elements are all inserted into the lower shell.

[0007] Preferably, the lower housing includes a pair of baffles, which are respectively disposed on the lower front and rear sides of the ABS plastic frame. The shape of the baffles matches the shape of the filter elements, and the shape of the baffles is a plurality of connected "V" shapes. The lower end of the filter element is provided with a second PP baffle plate, which is connected to the front and rear baffles.

[0008] Preferably, the bottom front and rear sides of the ABS plastic frame are provided with a number of wedge-shaped inserts. The inserts are inserted into the upper opening of the baffle, and the inserts fit the baffle. The thickness of the baffle is greater than that of the inserts, so that a groove is formed between the inserts and the baffle. The groove is filled with polyurethane two-component adhesive.

[0009] Preferably, the filter element includes a pair of plates arranged in a "V" shape, the cross-section of the plates is wavy, the plates are made of ultra-high molecular weight polyethylene and covered with a PET film.

[0010] Preferably, the number of the first PP baffle is three, and the number of the second PP baffle is four.

[0011] Preferably, the upper end of the filter element near both sides, on the side not connected to the first PP baffle, is connected to the ABS plastic frame via a third PP baffle.

[0012] The beneficial effects of this utility model are: the plastic-sintered V-type dust removal filter unit uses ultra-high molecular weight polyethylene sheet as the filter medium and is made into a V-flange structure dust removal filter unit. Through the combination of inserts, baffles and polyurethane two-component adhesive, it is easy to install and replace, saves installation site space, has no metal parts and is more resistant to acids and alkalis, and the V-shaped set of a pair of corrugated sheets to form the filter element reduces the height of the dust collector and reduces labor costs.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0019] Please see Figure 1-3 This utility model provides a technical solution: Example

[0020] A sintered V-shaped dust removal filter unit includes several filter elements, each filter element being V-shaped. The top ends of adjacent filter elements are connected. An ABS plastic frame 1 is provided above the filter elements. Several first PP baffles 2 are installed inside the ABS plastic frame 1. The connection point of a pair of adjacent filter elements is connected to the first PP baffles 2. A lower shell is provided on the lower side of the ABS plastic frame 1. The ABS plastic frame 1 and the filter elements are all inserted into the lower shell.

[0021] The lower housing includes a pair of baffles 3, which are respectively disposed on the lower front and rear sides of the ABS plastic frame 1. The shape of the baffles 3 matches the shape of several filter elements. The shape of the baffles 3 is multiple connected "V" shapes. The lower end of the filter element is provided with a second PP baffle 4, which is connected to the front and rear baffles 3.

[0022] Specifically, the filter element is made of ultra-high molecular weight polyethylene (commercially available product, abbreviated as UHMWPE). It is molded, sintered, and melted in one piece to form irregular pores inside the filter element. The outside is covered with a PET or PTFE membrane, which makes the surface of the substrate smooth and has excellent dust removal, waterproof and oil-proof effects. It can be used in working conditions with strong acids and alkalis.

[0023] The filter unit is entirely free of metal, providing superior corrosion resistance. The casing, after reaching the end of its service life, can be recycled and degraded for resource recovery, thus achieving energy conservation and environmental protection requirements.

[0024] The filter unit is V-shaped (or W-shaped), which greatly saves filter space and increases the filter area.

[0025] Example 2: The bottom front and rear sides of the ABS plastic frame 1 are provided with several wedge-shaped inserts 5. The inserts 5 are inserted into the upper opening of the baffle 3. The inserts 5 and the baffle 3 fit together. The thickness of the baffle 3 is greater than that of the inserts 5, so that a groove is formed between the inserts 5 and the baffle 3. The groove is filled with polyurethane two-component adhesive 6.

[0026] The filter element includes a pair of plates 7, which are arranged in a "V" shape. The cross-section of the plates 7 is wavy. The plates 7 are made of ultra-high molecular weight polyethylene and covered with a PET film.

[0027] There are three first PP baffle plates 2 and four second PP baffle plates 4.

[0028] The filter element near both sides, on the side not connected to the first PP baffle plate 2, is connected to the ABS plastic frame 1 via a third PP baffle plate.

[0029] Specifically, the filter unit includes: a plastic (PP+ABS) shell, an ultra-high molecular weight polyethylene sheet 7, a two-component polyurethane potting compound, and an EVA strip.

[0030] First, pour polyurethane two-component adhesive 6 onto both the top and bottom surfaces. After it solidifies, pour polyurethane two-component adhesive 6 into the tank sequentially. Clean the surface of dirt after the adhesive has completely solidified.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
