Abstract

The invention relates to a corrugated circular pipe filter formed by a plastic sinter board pipe coiling process and a manufacturing method of the corrugated circular pipe filter. The corrugated circular pipe filter is characterized in that corrugated toothed structures are arranged on the inner surface and the outer surface of a corrugated circular pipe filter element; the two ends of the corrugated circular pipe filter element are connected with each other in an embedded manner to form a coil pipe; the outside of the corrugated circular pipe filter element is sleeved with an socket joint sleeve and is connected with the socket joint sleeve by gluing; the inner cavity of the socket joint sleeve and the corrugated circular pipe filter element are same in outer diameter and shape, so that the corrugated circular pipe filter element can be inserted into the inner cavity of the socket joint sleeve in a butted manner. The manufacturing method comprises the following steps: adding a high-molecular-weight polyethylene material with the particle size of 20-100 meshes into a metal forming mould, putting the mould into a sintering box, gradually heating to enable plastic particles to form a formed product with micropores, cooling, coating the two ends of the plate-type product with a layer of adhesive, coiling to be in a circular pipe shape, and mutually embedding and shaping the glued edges of the two ends of the product to form the corrugated circular pipe filter. The corrugated circular pipe filter can be subjected to reverse jet-pulse cleaning and has numerous advantages of large filtering area, high filtering precision, energy conservation, emission reduction and the like, and the service life of the corrugated circular pipe filter is prolonged.

Example Embodiment

[0044] The present invention will be described in detail below in conjunction with the drawings and embodiments.
[0045] See Figure 1 to Figure 3 , The present invention provides a corrugated round tube filter formed by a plastic sintered plate rolling tube process. The corrugated round tube filter is mainly composed of a corrugated round tube filter element 1 and a socket sleeve 2.
[0046] Such as figure 1 As shown, the initial plastic sintered plate coil is a plate-shaped product, and the upper surface and the lower surface of the plate-shaped product are both corrugated tooth-like structures.
[0047] Such as figure 2 As shown, the plate-shaped product is rolled up to form a rolled tube, and the two ends of the rolled tube are fitted and connected to each other to form a corrugated round tube filter element 1. The inner surface and the outer surface of the corrugated tube filter element 1 are both corrugated tooth-like structures, and the tooth-shaped structures at both ends of the corrugated tube filter element 1 are fitted and connected to each other. In order to make the two ends of the corrugated round tube filter element 1 firmly connected, the tooth-like structures at both ends can be glued to fit and bond.
[0048] Such as image 3 As shown, the socket sleeve 2 is used as the coil length connecting piece of the corrugated round tube filter element 1, and the socket sleeve 2 is sleeved on the outside of the corrugated round tube filter element 1, and the two are glued and connected. The inner cavity of the socket sleeve 2 has the same shape as the outer diameter of the corrugated round tube filter element 1, which is convenient for butt insertion.
[0049] In practical applications, the corrugated round tube filter formed by the plastic sintered plate and tube rolling process of the present invention can be applied to a gas-solid separation device, and a socket sleeve is used in conjunction to make a cloth bag in a bag-type dust collector. The corrugated round tube filter of the present invention can also be directly used to manufacture the air purifier filter element. If the height dimension of the manufactured filter element is only a section of corrugated round pipe, it is unnecessary to use the socket sleeve.
[0050] The present invention also provides a method for manufacturing a corrugated round tube filter formed by the plastic sintering plate rolling process, and the specific steps are as follows:
[0051] (1) UHMWPE materials with an average molecular weight of 2-10 million are used. After screening, raw materials with a particle size of 20-100 mesh are selected for use. Ultra-high molecular weight polyethylene materials can preferably use 4.5 million average molecular weight. The ultra-high molecular weight polyethylene material can be selected preferably with a particle size of 40-80 mesh after screening.
[0052] (2) Install the metal forming mold, and gradually add the selected plastic materials through the feeding port until the cavity of the mold is densely filled. At this time, the materials in the cavity are extruded and stacked between particles, and the weight of the added raw materials is controlled .
[0053] (3) Put the added mold into the sintering box and gradually heat it up to 150℃~230℃, preferably 185℃. When heated to a certain time and temperature, the plastic particles in the mold cavity begin to melt and expand by heat. The plastic particles are squeezed and bonded in the space defined by the mold cavity, and the gaps between the particles form the micropores of the molded product. . During this period, the heating temperature and time should be strictly controlled. The time should be different according to the mold structure and the shape of the product. When the heating and sintering process is completed, the mold is removed from the sintering furnace for cooling.
[0054] (4) After the mold is cooled, the plate-shaped product is taken out. The plate after the mold has good flexibility and the mutual adhesion between the particles has a certain tensile strength, which is beneficial to the subsequent rolling process.
[0055] (5) Apply a layer of adhesive to the joints of the two ends of the plate-shaped product, roll the plate-shaped product into a round tube shape on the shaping equipment, and embed the glue at the edges of the two ends to form, that is, the coiled tube Teeth structures with corrugated two ends are fitted and connected to each other. In a specific implementation, a layer of silicone adhesive can be applied to the joints of the two ends of the roll tube. The size of the corrugated tooth at the edge of the two ends is the same as that of other corrugated teeth after shaping. Using this connection method can avoid and reduce the loss of filter area as much as possible, and keep the appearance consistent. The product has certain rigidity and strength after being rolled into a round tube and shaped.
[0056] (6) Check the formed corrugated round tube filter, and wait for use after being qualified. According to the existing test equipment, the wind resistance loss and dust removal efficiency can be checked.
[0057] In the manufacturing process of the corrugated round tube filter formed by the plastic-fired plate rolling pipe process of the present invention, the socket sleeve can be used as the length connector of the corrugated round tube filter, and the socket sleeve is sleeved on the corrugated round tube to filter The outside of the filter is connected with glue to replace the bag in the bag filter, or to manufacture corrugated round tube filter products that require a certain height.
[0058] To sum up, according to the present invention, a corrugated round tube filter formed by a plastic sintered plate rolling tube process and a manufacturing method thereof, use ultra-high molecular weight polyethylene plastic powder particles to be sintered in a mold into a fully penetrating micropore It also has a corrugated plastic sintered plate-shaped product, which can be rolled into a circular tube shape and then connected and shaped into a circular tube-shaped filter with a corrugated surface. Because the rigid structure of the corrugated tube filter can withstand pulse back blowing and self-cleaning, the airflow is obvious, the service life is improved, and it has many advantages such as large filtering area, high filtering accuracy, energy saving and emission reduction.
[0059] Of course, those of ordinary skill in the art should realize that the above-mentioned embodiments are only used to illustrate the present invention, but not to limit the present invention. As long as the changes to the above-mentioned embodiments are within the essential spirit of the present invention, , Variants, etc. will fall within the scope of the claims of the present invention.
