Description

Technical Field

[0001] The utility model relates to the technical field of novel winding filter elements, in particular to a novel winding filter element. Background Art

[0002] The wound filter element is made of textile fiber yarn with good filtering performance precisely wound on a porous skeleton.

[0003] For example, a new type of wound filter element with the authorization announcement number "CN205199133U" has no foreign matter precipitated during use, and can be used to filter liquids such as food, beverages, and traditional Chinese medicine. It is safe and reliable, and the product does not contain any external spinning oils or additives such as surfactants, softeners, and lubricants. It is used in industries such as electroplating and PCB manufacturing. No pre-soaking is required, and the filtrate is foam-free. There is no fiber shedding during the use of the new type of wound filter element, and no secondary pollution of the filtrate is caused. The product has a short production process and low cost, and is easier to mass-produce industrially. However, in the use of the wound filter element, in high turbidity water conditions, the filter element will be more easily clogged and need to be replaced frequently. When the wound filter element is used for replacement, its service life is basically over. It is easy to break when collected, and it needs to be collected multiple times, which increases the difficulty of replacing the wound filter element and reduces work efficiency. Utility Model Content

[0004] The utility model aims to solve the problem that the replacement difficulty of a winding filter element is increased and the working efficiency is reduced, and a new winding filter element is proposed.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A novel wound filter element is designed, comprising a grid frame and a wound filter element, wherein the outer wall of the grid frame is fixedly connected to the inner wall of the wound filter element, the front of the inner wall of the grid frame is connected to a control structure, the rear of the outer wall of the wound filter element is sleeved with an outer shell, the rear end face of the outer shell is connected to a straight cylinder, and the inner wall of the straight cylinder is plugged into the rear of the outer wall of the grid frame.

[0007] Preferably, the control structure comprises a circular plate and a straight rod, the outer wall of the circular plate is fixedly connected to the front of the inner wall of the grid, the inner wall of the circular plate fits the outer wall of the straight rod, and the rear end face of the straight rod is fixedly connected with a baffle.

[0008] Preferably, a handle is fixedly connected to the front side of the straight rod.

[0009] Preferably, the diameters of the baffle and the handle are both larger than the inner diameter of the circular plate.

[0010] Preferably, a circular ring is sleeved in front of the outer wall of the winding filter element.

[0011] Preferably, the diameter of the ring is consistent with the diameter of the housing.

[0012] The utility model proposes a novel wound filter element, which has the beneficial effect of holding the handle in the control structure and pulling it forward, and the moving handle brings the straight rod to move forward on the inner wall of the circular plate, and the moving straight rod brings the baffle forward until the front of the baffle fits with the back of the circular plate. At this time, the circular plate limits the position of the baffle, and the baffle is tightened at this time, and then moves forward with the circular plate, and the moving circular plate brings the grid and the wound filter element forward, so that the wound filter element gradually separates from the inner wall of the filter, avoids direct collection by hands, reduces the difficulty of replacing the wound filter element, and improves work efficiency.

[0018] The utility model is further described below in conjunction with the accompanying drawings:

[0019] Embodiment 1:

[0020] See also Figure 1-4 In the present embodiment, a new type of winding filter element includes a mesh frame 1 and a winding filter element 4. The outer wall of the mesh frame 1 is fixedly connected to the inner wall of the winding filter element 4. The mesh frame 1 is made of stainless steel. A control structure 2 is connected to the front of the inner wall of the mesh frame 1. An outer shell 5 is sleeved on the rear of the outer wall of the winding filter element 4. The material of the winding filter element 4 is absorbent cotton fiber. The rear end face of the outer shell 5 is connected to a straight cylinder 6. The inner wall of the straight cylinder 6 is plugged into the rear of the outer wall of the mesh frame 1.

[0021] The control structure 2 includes a circular plate 201 and a straight rod 202. The outer wall of the circular plate 201 is fixedly connected to the front of the inner wall of the grid 1. The inner wall of the circular plate 201 fits the outer wall of the straight rod 202. The straight rod 202 is forced to move forward and backward through the inner wall of the circular plate 201. A baffle 203 is fixedly connected to the rear end face of the straight rod 202. A handle 204 is fixedly connected to the front face of the straight rod 202. The handle 204 is convenient for pulling the straight rod 202 to move.

[0022] By holding the handle 204 in the control structure 2 and pulling it forward, the moving handle 204 moves forward with the straight rod 202 on the inner wall of the circular plate 201, and the moving straight rod 202 moves forward with the baffle 203 until the front of the baffle 203 fits with the back of the circular plate 201. At this time, the circular plate 201 limits the position of the baffle 203, and the baffle 203 is tightened at this time, and then moves forward with the circular plate 201. The moving circular plate 201 moves forward with the grid 1 and the wound filter element 4, so that the wound filter element 4 gradually separates from the inner wall of the filter, avoiding direct collection by hands, reducing the difficulty of replacing the wound filter element, and improving work efficiency.

[0023] The diameters of the baffle 203 and the handle 204 are both larger than the inner diameter of the circular plate 201. A circular ring 7 is sleeved in front of the outer wall of the wound filter element 4. The diameter of the circular ring 7 is consistent with the diameter of the outer shell 5. The circular ring 7 and the outer shell 5 retract the outer wall side of the wound filter element 4 to prevent the side of the wound filter element 4 from loosening.

[0024] Working principle:

[0025] Installation of spiral wound filter element:

[0026] The outer walls of the shell 5 and the straight cylinder 6 are inserted into the inner wall of the filter until the wound filter element 4 is completely inserted into the filter. The ring 7 and the shell 5 can prevent the wound filter element 4 from directly contacting the inner wall of the filter, prevent the outer wall of the wound filter element 4 from being scratched, and at the same time improve the stability of the wound filter element 4 inside the filter.

[0027] Replacement of spiral filter element:

[0028] When replacing the wound filter element 4, hold the handle 204 and pull it forward. The moving handle 204 moves the straight rod 202 forward along the inner wall of the circular plate 201, and the moving straight rod 202 moves the baffle 203 forward until the front of the baffle 203 fits with the back of the circular plate 201. At this time, the circular plate 201 limits the position of the baffle 203, and the baffle 203 is tightened at this time, and then moves forward with the circular plate 201. The moving circular plate 201 moves forward with the grid 1 and the wound filter element 4, so that the wound filter element 4 gradually separates from the inner wall of the filter to avoid direct collection by hands.

[0029] Embodiment 2:

[0030] See also Figure 1-4: In this embodiment, a new type of winding filter element also includes a cavity 3, and the outer walls of the multiple cavities 3 are all processed with a circular plate 201.

[0031] Working principle:

[0032] When the wound filter element 4 is working, the filtrate can flow through the cavity 3 on the outer wall of the circular plate 201 through the grid 1, and the cavity 3 can avoid being blocked by the circular plate 201.

[0033] Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
