Description

Technical Field

[0001] The present application relates to the technical field of industrial system air purification filters, and in particular to a V-type filter. Background Art

[0002] The working principle of the air purification filter is to pass the waste gas generated in the industrial production process through the filter element of the air filter, thereby filtering the particulate matter, harmful gases, bacteria and viruses contained in the industrial waste gas through the filter element to achieve the purpose of industrial waste gas purification.

[0003] Traditional filter elements are coated with glue lines to fix the structural shape of the filter element and improve the sealing performance of the filter element. Conventional filter element glue lines are intermittent glue lines, such as the utility model patent with patent number CN202010483U.

[0004] In the actual industrial production process, the production speed of industrial waste gas will accelerate with the expansion of industrial production scale. There is a situation where an air filter with a CADR value (Clean Air Delivery rate) of more than 3000 is required to meet the demand for purifying industrial waste gas. The CADR value of conventional intermittent rubber line air filters is generally 300-800. When the purification air volume of the intermittent rubber line air filter is greater than the rated CADR value, the filter element of the air filter is easily damaged by the excessive air volume, causing the filter element to break and the filter element to be unable to continue to perform the filtering function. Therefore, there is a problem that the purification air volume of the existing air filter is too low and cannot meet the demand for industrial waste gas purification alone. Utility Model Content

[0005] In order to increase the purification air volume of the air filter and meet the needs of industrial waste gas purification, the present application provides a V-type filter.

[0006] The V-type filter provided in this application adopts the following technical solution:

[0007] A V-type filter, comprising:

[0008] The filter element is made of a whole piece of filter paper folded together and is used to filter the air;

[0009] A glue line is bonded to the side of the filter element, the glue line is continuously arranged in contact with the filter paper, and two ends of the glue line are respectively connected to two ends of the filter paper;

[0010] An outer frame abuts against the filter element and is bonded to the adhesive wire to support the filter element.

[0011] By adopting the above technical solution, the glue line is set as a continuous glue line and is arranged in close contact with the filter paper. The continuous glue line can withstand greater force when the filter takes in air, and the glue line can be combined with the outer frame. Compared with the intermittent glue line in the prior art, it can withstand greater wind resistance, and thus can maintain the structure of the filter element at a higher air purification speed, ultimately increasing the purified air volume of the air filter and meeting the needs of industrial waste gas purification.

[0012] Optionally, the filter element includes a first filter plate and a second filter plate, the first filter plate is formed by repeatedly folding the filter paper along a first direction, the second filter plate is formed by repeatedly folding the filter paper along a second direction, the first direction and the second direction are cross-arranged, and the first filter plate and the second filter plate form a V-shaped structure.

[0013] By adopting the above technical solution, the first filter plate and the second filter plate formed by repeated folding of the filter paper cross to form a V-shaped structure, and the V-shaped structure is combined with the outer frame to form a stable triangular structure, thereby further increasing the stability of the filter element structure. At the same time, the filter paper is folded while driving the glue line to fold. Due to the continuity of the glue line, the glue line is combined with the outer frame during folding to achieve the connection between the outer frame and the filter paper. Since the filter paper is a whole sheet of filter paper and is not cut, the filter paper itself can be used as a sealing surface, reducing the process of applying sealant, greatly reducing the amount of sealant used and the production cost of the filter element.

[0014] Optionally, the filter paper can be folded repeatedly by changing the folding direction for multiple times to form a V-shaped structure with a number greater than 2 and continuous.

[0015] By adopting the above technical solution, the continuous V-shaped structure can increase the number of times the industrial waste gas is filtered, thereby enhancing the purification effect of the filter.

[0016] Optionally, the outer frame includes a bottom frame, a top frame, a first side frame and a second side frame, the bottom frame abuts against the bottom end of the filter element and is bonded to the glue line, the top frame abuts against the top end of the filter element and is bonded to the glue line, the first side frame and the second side frame are located on opposite sides of the filter element, the top end of the first side frame is connected to the top frame, the bottom end of the first side frame is connected to the bottom frame, the top end of the second side frame is connected to the top frame, and the bottom end of the second side frame is connected to the bottom frame.

[0017] By adopting the above technical solution, the bottom frame, the top frame, the first side frame and the second side frame together form a support frame for the filter element. The outer frame is connected to the filter element by bonding with glue wire, thereby finally achieving the function of providing support for the filter element.

[0018] Optionally, the first side frame is configured as a plurality of continuous V-shaped plates, the V-shaped plates are provided with a V-shaped groove on one side facing the filter element, both sides of the V-shaped structure are sealed against the groove walls of the V-shaped groove, and the structure of the second side frame is consistent with that of the first side frame.

[0019] By adopting the above technical solution, a V-shaped groove is opened on the V-shaped plate to better fit the side of the V-shaped structure, thereby enhancing the sealing performance of the connection between the V-shaped structure and the V-shaped plate.

[0020] Optionally, a weight-reducing groove is provided on a side of the V-shaped plate facing away from the filter element, and the weight-reducing groove is located within an angle between the first filter plate and the second filter plate.

[0021] By adopting the above technical solution, a weight-reducing groove is opened on the V-shaped plate, which can reduce the weight of the V-shaped plate, thereby reducing the weight of the filter, reducing the production cost of the V-shaped plate, and facilitating the transportation of the filter.

[0022] Optionally, the top frame includes a first connecting plate, a second connecting plate and a reinforcing rod, the first connecting plate is perpendicular to the first direction, the first connecting plate abuts against the first filter plate on the side facing the filter element and is bonded to the glue line, the second connecting plate is perpendicular to the second direction, the second connecting plate abuts against the second filter plate on the side facing the filter element and is bonded to the glue line, the first connecting plate and the second connecting plate are fixedly connected on both sides of the reinforcing rod, and the two ends of the reinforcing rod are respectively connected to the first side frame and the second side frame.

[0023] By adopting the above technical solution, the top frame is divided into a first connecting plate, a second connecting plate and a reinforcing rod. The first connecting plate is perpendicular to the first direction, which can make it more convenient to connect the first connecting plate with the first filter plate. The second connecting plate is perpendicular to the second direction, which makes it convenient to connect the second connecting plate with the second filter plate. Then, the first connecting plate and the second connecting rod are connected by the reinforcing rod, which enhances the connection strength between the first connecting plate and the second connecting plate, and finally enhances the connection strength between the filter element and the top frame.

[0024] Optionally, the reinforcing rod is configured as a hollow rod, and a clamping joint is connected to a side of the first side frame and the second side frame facing the reinforcing rod, and the clamping joint is clamped to the reinforcing rod.

[0025] By adopting the above technical solution, the hollow reinforcement rod reduces the weight of the reinforcement rod, provides a clamping space between the clamping joint and the reinforcement rod, and facilitates the installation and disassembly of the reinforcement rod.

[0026] Optionally, the bottom frame is provided with a plurality of parallel limiting grooves, the bottom ends of the first filter plate and the second filter plate abut against the groove walls of the limiting grooves, and the glue line is bonded to the groove walls of the limiting grooves.

[0027] By adopting the above technical solution, the limiting groove provides a space for fitting the first filter plate and the second filter plate, thereby enhancing the sealing performance between the first filter plate and the bottom frame, while enhancing the sealing performance between the second filter plate and the bottom frame. The limiting groove defines the positions of the first filter plate and the second filter plate, thereby reducing the probability of deformation of the first filter plate and the second filter plate and enhancing the stability of the filter element structure.

[0028] Optionally, weight-reducing holes are provided on the peripheral side of the bottom frame.

[0029] By adopting the above technical solution, the weight-reducing holes reduce the weight of the bottom frame, reduce the production cost of the bottom frame, and facilitate the assembly of the bottom frame and the transportation of the filter.

[0031] 1. Set the glue line in the filter as a continuous glue line, then bond the continuous glue line to the filter paper of the filter element, and combine the filter element with the outer frame, so that the filter paper in the filter element can withstand greater wind resistance without being damaged, so that the filter has a basis for a larger purified air volume, improves the purified air volume of the air filter, and meets the purification needs of industrial waste gas;

[0032] 2. The filter element is set to a V-shaped structure composed of a first filter plate and a second filter plate formed by repeatedly folding a whole piece of filter paper. The V-shaped filter element is then combined with the outer frame to form a stable triangular structure, which improves the stability of the filter element structure. At the same time, since the filter paper itself is not cut, the filter paper itself can be used as a sealing surface, reducing the process of applying sealant to the sealing surface for sealing, reducing the amount of sealant used and the production cost of the filter element;

[0033] 3. The top frame is divided into three parts: a first connecting plate, a second connecting plate and a reinforcing rod.

[0042] The following is combined with Figure 1-7 This application is described in further detail.

[0043] The present application embodiment discloses a V-type filter. Figure 1 and Figure 2 A V-shaped filter includes a filter element 1, a rubber wire 2 and an outer frame 3.

[0044] The filter element 1 is located on the air flow path in the filter and is formed by folding a whole piece of filter paper 11. The glue line 2 is a continuous glue line 2, which is attached to the surface of the filter paper 11, and the two ends of the glue line 2 overlap with the two ends of the filter paper 11. The outer frame 3 is located on the peripheral side of the filter element 1, and the outer frame 3 abuts against the filter element 1 and is bonded to the glue line 2.

[0045] The filter element 1 provides a purification function within the filter. The filter element 1 made of a whole piece of filter paper 11 can improve the integrity of the filter element 1, thereby enhancing the sealing performance of the filter element 1. The glue line 2 is bonded to the surface of the filter paper 11, and the glue line 2 is a continuous glue line 2, thereby enhancing the strength of the filter paper 11, so that the filter paper 11 can withstand greater wind resistance without being damaged. The outer frame 3 provides support for the filter element 1, so that the filter element 1 can maintain structural stability under large air volume conditions. Finally, the purified air volume of the air filter is increased, meeting the needs of industrial waste gas purification.

[0046] Reference Figure 1 and Figure 3The filter element 1 includes a first filter plate 1111 and a second filter plate 1112 which are connected and cross-arranged at one end. The first filter plate 1111 is formed by repeatedly folding the filter paper 11 along the first direction 4. The second filter plate 1112 is formed by bending the filter paper 11 to form the first filter plate 1111 and then repeatedly folding along the second direction 5. The first filter plate 1111 and the second filter plate 1112 form a V-shaped structure 111. After the first filter plate 1111 and the second filter plate 1112 are folded, the filter paper 11 can continue to fold to form a number greater than 2 and continuous V-shaped structures 111.

[0047] The first filter plate 1111 and the second filter plate 1112 formed by repeated folding of the filter element 1 increase the filtration area of ​​the filter element 1. The V-shaped structure 111 formed by the first filter plate 1111 and the second filter plate 1112 is combined with the outer frame 3 to form a stable triangular structure, thereby enhancing the stability of the structure of the filter element 1. When the filter paper 11 is folded to form a number of V-shaped structures 111 greater than 2 and continuous, the number of air filtrations can be increased, thereby enhancing the effect of air purification. At the same time, the continuous V-shaped structure 111 forms a continuous triangular structure with the outer frame 3, and the structural stability of the filter element 1 is further enhanced. Since the V-shaped structure 111 is formed by folding a whole piece of filter paper 11, and the filter paper 11 is not cut, the filter paper 11 itself can be used as a sealing surface for air filtering, and no additional gluing process is required to ensure the sealing performance of the sealing surface, which reduces the amount of sealant used and reduces the production cost of the filter element 1.

[0048] Reference Figure 1 The outer frame 3 includes a bottom frame 31, a top frame 32, a first side frame 33, and a second side frame 34. The bottom frame 31 is located at the bottom end of the filter element 1 and is bonded to the glue line 2 at the bottom end of the filter element 1. The top frame 32 is located at the top end of the filter element 1 and is bonded to the glue line 2 at the top end of the filter element 1. The first side frame 33 and the second side frame 34 are located between the bottom frame 31 and the top frame 32, and both ends of the first side frame 33 and the second side frame 34 abut against the bottom frame 31 and the top frame 32, respectively. The first side frame 33 and the second side frame 34 abut against the opposite sides of the filter element 1, respectively.

[0049] The bottom frame 31, the top frame 32, the first side frame 33 and the second side frame 34 work together to frame the filter element 1, provide a supporting structure for the filter element 1, and connect the filter element 1 with the parts of the outer frame 3 through the glue line 2 bonded to the filter paper 11, so as to achieve the purpose of improving the overall structural strength of the filter.

[0050] Reference Figure 1 and Figure 4 A plurality of limiting grooves 311 are provided on one side of the bottom frame 31 facing the filter element 1, and the number of the limiting grooves 311 matches the number of the V-shaped structures 111. The bottom ends of the first filter plate 1111 and the second filter plate 1112 are both in contact with the limiting grooves 311, and the groove walls of the limiting grooves 311 are bonded to the rubber line 2. Weight-reducing holes 312 are provided on the peripheral side of the bottom frame 31, and the shape of the weight-reducing holes 312 is preferably square.

[0051] The limiting groove 311 on the bottom frame 31 facilitates the connection of the first filter plate 1111 and the second filter plate 1112 to the bottom frame 31. After the first filter plate 1111 and the second filter plate 1112 are connected to the bottom frame 31, the limiting groove 311 limits the position of the first filter plate 1111 and the second filter plate 1112, reduces the probability of deformation of the first filter plate 1111 and the second filter plate 1112, and further improves the structural stability of the first filter plate 1111 and the second filter plate 1112. The weight-reducing holes 312 provided on the bottom frame 31 can reduce the weight of the bottom frame 31, facilitate the installation of the bottom frame 31, and facilitate the transportation of the filter.

[0052] Reference Figure 1 and Figure 5 The top frame 32 includes a first connecting plate 321, a second connecting plate 322 and a reinforcing rod 323. The first connecting plate 321 and the second connecting plate 322 are respectively located on both sides of the reinforcing rod 323 and are both fixedly connected to the reinforcing rod 323. The layout direction of the first connecting plate 321 is perpendicular to the first direction 4, the side of the first connecting plate 321 facing the filter element 1 abuts against the top of the first filter plate 1111, the layout direction of the second connecting plate 322 is perpendicular to the second direction 5, the side of the second connecting plate 322 facing the filter element 1 abuts against the top of the second filter plate 1112, the glue line 2 on the top of the first filter plate 1111 is bonded to the first connecting plate 321, and the glue line 2 on the top of the second filter plate 1112 is bonded to the second connecting plate 322. Both ends of the first connecting plate 321 and the second connecting plate 322 abut against the first side plate and the second side plate, respectively.

[0053] The first connecting plate 321 is connected to the first filter plate 1111 in a vertical and convenient manner, and does not give the first filter plate 1111 a force for deflection, thereby improving the structural stability of the first filter plate 1111. The second connecting plate 322 similarly improves the structural stability of the second filter plate 1112. Then, the first connecting plate 321 and the second connecting plate 322 are connected by a reinforcing rod 323, thereby enhancing the connection strength of the first connecting plate 321 and the second connecting plate 322, and finally increasing the connection strength between the filter element 1 and the top frame 32.

[0054] The reinforcing rod 323 is a hollow rod, and a clamping block is fixedly connected to the first side plate and the second side plate on one side facing the reinforcing rod 323, and the clamping block is clamped with both ends of the reinforcing rod 323. The hollow reinforcing rod 323 reduces the weight of the reinforcing rod 323 and provides a clamping space for the reinforcing rod 323 and the clamping block, thereby facilitating the connection and disassembly of the reinforcing rod 323 and the first side frame 33 and the second side frame 34.

[0055] Reference Figure 1 , Figure 6 and Figure 7, the structures of the first side frame 33 and the second side frame 34 are consistent. The first side frame 33 is in the shape of a plurality of continuous V-shaped plates 331, and the number of the V-shaped plates 331 is consistent with the number of the V-shaped structures 111. A V-shaped groove 3311 is provided on the side of the V-shaped plate 331 facing the filter element 1, and the side wall of the V-shaped structure 111 abuts against the groove wall of the V-shaped groove 3311. A weight-reducing groove 3312 is provided on the side of the V-shaped plate 331 facing away from the filter element 1, and the weight-reducing groove 3312 is provided between the angles of the first filter plate 1111 and the second filter plate 1112, and the bottom of the weight-reducing groove 3312 is inclined from the direction of the bottom frame 31 to the top frame 32 toward the direction of the second side frame 34.

[0056] The V-shaped groove 3311 is arranged to fit the side of the V-shaped structure 111, so that after the V-shaped structure 111 is combined with the V-shaped plate 331, the connection between the V-shaped structure 111 and the V-shaped plate 331 will be tighter, thereby enhancing the sealing performance of the connection between the V-shaped structure 111 and the V-shaped plate 331. The opening of the weight-reducing groove 3312 can reduce the weight of the V-shaped plate 331, facilitate the transportation and installation of the V-shaped plate 331, and thus facilitate the installation and transportation of the filter. The bottom of the V-shaped groove 3311 arranged obliquely can make the structural strength of the V-shaped plate 331 near the bottom frame 31 greater, thereby reducing the probability of damage to the V-shaped plate 331 near the bottom frame 31.

[0057] The implementation principle of a V-type filter in an embodiment of the present application is as follows: during the use of the filter, the continuous glue line 2 bonded to the filter paper 11 can divide the filter paper 11 into multiple blocks and provide additional support for the filter paper 11. The filter paper 11 is then connected to the outer frame 3 through the glue line 2, so that the filter paper 11 can withstand greater wind resistance without being damaged, providing a basis for the filter to have a larger purification air volume, increasing the purification air volume of the air filter, and meeting the purification needs of industrial waste gas.

[0058] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
