Description

Filter tube

This creation is related to the filter tube, especially a filter tube sintered from a polymer material, and used in a pulse bag filter.

According to the conventional pulse type bag filter, when the gas passes through the filter bag, the dust in the gas is adsorbed on the outer surface of the filter bag to achieve the filtering effect.

However, after a period of use, the excessive accumulation of dust on the outer surface of the filter bag will result in a lowering of the effect of filtering the exhaust gas. At this time, it is necessary to perform a cleaning process, and in the cleaning process, the high-pressure air is blown into the filter bag, so that The filter bag is inflated, and the dust on the outer surface of the filter bag is shaken in an instant to restore the original shape and continue to be used.

However, in the cleaning process, the filter bag is easy to generate multiple impacts and collisions with the frame supporting the filter bag during the expansion process, resulting in damage to the surface of the filter bag and loss of its own performance, and the filter bag is inflated; further, the outer surface of the filter bag When ventilating and filtering dust, the filtering effect is not excellent due to the small filtering area, so the structure of the conventional filter bag for filtering has room for improvement.

In order to solve the above problems, the present invention discloses a filter tube which has an inner and outer surface of a continuous curved wrinkle, thereby increasing the filtering area, enhancing the dust capturing effect, and replacing the conventional filter bag to improve the service life.

In order to achieve the above object, the present invention provides a filter tube which is sintered from a polymer material and comprises: a body which is a hollow circular tube with a microporous structure, and the inner surface and the outer surface of the body are continuously curved. a wrinkle; and a support member that is hollowed out and connected to the inner surface of the body.

Wherein, the support member comprises a first portion connected to the inner surface of the body and a second portion connected to the first portion and located at the axis of the body.

The first part is a plurality of long rods, one end of which is connected to the inner surface of the body, and the second part is annular, for the other end of the long rod to be connected.

Wherein, the inner surface of the body has a plurality of recesses and a plurality of protrusions arranged at intervals, and the long rods are equidistantly connected to the protrusions.

Wherein, each two adjacent long rods are arranged at intervals of 60 degrees.

The first portion and the second portion each have a first cutting surface and a second cutting surface disposed opposite to each other, and the first cutting surface and the second cutting surface are tapered and facing the open end of the body.

Wherein, one end of the body has a joint portion for the other filter tube to be axially connected to the joint portion in a concave-convex manner.

Wherein, the joint portion is integrally formed on the body.

Further, the system includes a set of the system sleeved on the body, the sleeve body and the body have corresponding shapes and the same material, and the joint portion is formed by the axial length difference between the body and the sleeve body.

Wherein the support member is adjacent to the opening of the body.

Therefore, the present invention uses its continuous curved wrinkles to increase the filtering area and enhance the dust capturing effect, and the conventional inner frame does not need to be additionally disposed in the filter tube, so that it is less prone to wear during cleaning, and the loss cost can be reduced. . In addition, the number of filter tubes can be arbitrarily added according to the length of the demand, and has a wide range of applications.

For the convenience of the description, the central idea expressed in the above-mentioned creation content column is expressed by a specific embodiment. The various items in the embodiments are set forth in proportion to the description and not in the

Referring to FIG. 1 to FIG. 5, the present invention is a filter tube 100 which is sintered from a polymer material and is suitable for use in a pulse filter device for filtering dust. The filter tube 100 is heated and sintered by placing the plastic powder or particles in a molding die so that the molded article has a certain structural strength, and the filter tube 100 includes a body 10 and a support member 20.

The body 10 is a hollow circular tube with a microporous structure, and the inner surface and the outer surface of the body 10 are continuously curved and wrinkled, so that the body 10 can increase the filtration area and improve the filtering effect by the continuous curved wrinkles. The inner surface of the body 10 has a plurality of recesses 11 and a plurality of protrusions 12 arranged at intervals. The recesses 11 of the inner surface are correspondingly convex portions of the outer surface, and the protrusions 12 of the inner surface are corresponding to the outer surface. The concave part.

The support member 20 is hollowed out and connected to the inner surface of the body 10 for reinforcing the structural strength of the body 10. The support member 20 is integrally disposed on the body 10 but is not limited thereto. The support member 20 includes a first portion 21 and a second portion 22 integrally formed. The first portion 21 is coupled to the inner surface of the body 10 and is coupled to the protrusion 12 of the inner surface. The second portion 22 is coupled to the first portion 21 and located At the axis of the body 10. As shown in FIG. 3, in the present embodiment, the first portion 21 has a plurality of long rods, the number of which is six, and the second portion 22 is annular, and one end of the long rod is connected to the inner surface of the body 10. a protrusion 12, and the other end of the long rod is connected to the second portion 22, and each two long rods are disposed at intervals of 60 degrees, so that the first portion 21 is equiangularly disposed on the inner surface and the second portion of the body 10. Between 22.

In addition, the body 10 is open at both ends, and the first portion 21 and the second portion 22 of the support member 20 respectively have a first cutting surface 211, 221 and a second cutting surface 212, 222 disposed oppositely, and the first cutting surface 211, The 221 and the second cutting surfaces 212 and 222 have a tapered shape and face the open end of the body 10, in particular, the air inlet end of the body 10, and the first cutting surfaces 211, 221 and the second cutting surface 212 are disposed to increase the gas. Enter the flow guiding effect of the body 10 without increasing the resistance of the gas.

As shown in FIG. 2 and FIG. 4, one end of the body 10 has a joint portion 13 for the other filter tube 100a to be axially connected to the joint portion 13 in a concave-convex manner, so as to have the effect of extending the length. In the present embodiment, the joint portion 13 is disposed at both axial ends of the body 10, and the joint portion 13 may be integrally formed on the body 10, or may be sleeved on the body 10 by a set of bodies 30, and is closely related to the body 10. The sleeve body 30 has a corresponding shape and the same material as the body 10, and the joint portion 13 is formed by the axial length difference between the body 10 and the sleeve body 30. Therefore, in the present invention, a plurality of filter tubes 100a can be arbitrarily set to the body 10 in order to achieve an effect of extending the growth. In addition, a sealing member may be further added to the end of the filter tubes 100, 100a to increase the overall structural strength.

Thereby, the body 10 of the filter tube 100 or the sleeve body 30 is creased by its continuous arc, which increases the filtering area and enhances the capturing effect of the dust, and the filter tube 100 does not need to be provided with a conventional inner frame. When cleaning, it is less prone to wear and can reduce the cost of loss.

In addition, the creation can be directly used in the current pulse filter bag equipment without modifying the existing equipment, and the life of the creation can be greatly extended to more than 10 times compared with the conventional filter bag, thereby reducing the operation and operation cost. Economic advantage.

This creation is also an environmentally-friendly product that can be reused and used, and can be extended and arbitrarily extended under the length requirement, which is highly industrially usable.
