Description

Technical Field

[0001] The utility model relates to the technical field of waterproof coiled material production equipment, in particular to a filtering device used for a pre-invasion oil pool of a waterproof coiled material production line. Background Art

[0002] Waterproofing membrane is mainly used in building walls, roofs, tunnels, roads, landfills, etc. It is a kind of flexible building material product that can be rolled into a roll to prevent the leakage of rainwater and groundwater from the outside. As a leak-free connection between the engineering foundation and the building, it is the first barrier of the entire project waterproofing and plays a vital role in the entire project. The main products are asphalt waterproofing membrane and polymer waterproofing membrane.

[0003] The pre-infiltration oil pool is used to hold the softened asphalt, and then the tire cloth is immersed in the pre-infiltration oil. Although the softened asphalt semi-finished product has a certain fluidity, it is very viscous and is easy to clog the filter holes when passing through the porous filter device, resulting in reduced filtration efficiency. The existing technology often requires the entire production line to be shut down, and then the entire filter device is disassembled and the mesh is cleared before the machine can be started again for production. This method is time-consuming and labor-intensive, and seriously affects the production speed of the production line. Utility Model Content

[0004] In order to solve the above problems, the purpose of the utility model is to provide a device that can conveniently and quickly clean the blocked mesh of the filter, avoid the clogging of the filter mesh by semi-finished asphalt with high viscosity, increase the production rate and save labor costs.

[0005] In order to achieve the above objectives, the technical solution adopted by the utility model is:

[0006] A filtering device for a pre-invasion oil pool of a waterproofing coiled material production line comprises a filtering tank, a scraper and a telescopic cylinder; the surface of the filtering tank is evenly distributed with a plurality of filtering through holes; the scraper is vertically arranged in the filtering tank and abuts against the inner surface of the filtering tank; the telescopic cylinder is arranged near the outer side of the end of the filtering tank.

[0007] In some preferred embodiments, an end plate is further included; the end plate is disposed at an end of the filter tank away from the telescopic cylinder.

[0008] In some preferred embodiments, the telescopic cylinder is a multi-stage telescopic cylinder.

[0009] In some preferred embodiments, the number of the scraper and the number of the telescopic cylinder are both 2; the telescopic cylinder is respectively arranged on the outer sides of both ends of the filter tank and the telescopic directions are opposite.

[0010] Beneficial effects: The utility model can clean the clogged filter mesh conveniently and quickly without stopping the entire production line and disassembling the entire filtering device, thus saving time and effort, improving the production rate and saving labor costs.

[0016] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described below in conjunction with the accompanying drawings. In the description of the utility model, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0017] like Figure 1 As shown, this embodiment discloses a filtering device for pre-invasion oil pool of waterproof membrane production line, including a filter tank 1, a scraper 2 and a telescopic cylinder 3; the surface of the filter tank 1 is evenly distributed with a plurality of filtering through holes; the scraper 2 is vertically arranged in the filter tank 1 and abuts against the inner surface of the filter tank 1; the telescopic cylinder 3 is arranged near the outer side of the end of the filter tank 1.

[0018] like Figure 2 As shown, when the filter through hole is blocked and needs to be cleaned, the telescopic cylinder 3 is controlled to work, driving the scraper 2 to slide back and forth, thereby scraping the blocked filter through hole. Figure 2 As shown, in order to prevent the remaining semi-finished asphalt in the filter tank 1 from overflowing from the other end due to being pushed by the scraper 2, an end plate 4 is considered to be provided, and the end plate 4 is provided at the end of the filter tank 1 away from the telescopic cylinder 3.

[0019] like Figure 2 As shown, considering that the length of the filter tank 1 is generally long, mostly around 2-3m, a single-stage telescopic cylinder 3 is difficult to extend to this length, so in some preferred embodiments, a multi-stage telescopic cylinder 3 is considered. It should be understood that the telescopic cylinder 3 in the utility model can be a telescopic air cylinder, a telescopic oil cylinder, or an electric telescopic cylinder 3. The multi-stage telescopic cylinder 3 can be a multi-section telescopic electric cylinder of the Ruilian brand RLD-S model, and the stroke of the telescopic cylinder 3 is determined according to the length of the filter tank 1. On the other hand, the utility model also includes other necessary auxiliary equipment that is matched with the telescopic cylinder 3, such as air cylinders, oil cylinders, motors, switches, telescopic cylinder 3 mounting brackets, etc. Since this part of the content is conventional technology in the field, it is not specifically described in this embodiment. Those skilled in the art can choose the specific model and setting method according to the actual needs of the site, and the utility model will not be further limited.

[0020] like Figure 3 , Figure 4 As shown, in other preferred embodiments, considering that the stroke of the single telescopic cylinder 3 may not cover the entire length of the filter tank 1, the number of the scraper 2 and the telescopic cylinder 3 are both set to 2, and the telescopic cylinder 3 is respectively arranged at the outer sides of the two ends of the filter tank 1 and the telescopic directions are opposite. When working, the two telescopic cylinders 3 are respectively extended from the two ends to the middle, which can not only cover the length of the entire filter tank 1, but also reduce the stroke of a single telescopic cylinder 3.

[0021] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
