Description

Technical Field

[0001] The utility model relates to the field of glass fiber equipment, in particular to an impregnating agent oil return filtering device. Background Art

[0002] After the impregnating agent used in the wire drawing process is prepared, it is first input into a storage tank, and then from the storage tank into a circulation tank. The circulation tank transports the impregnating agent to the oiling box. The excess impregnating agent in the oiling box passes through a section of pipe, and then is filtered through a return oil box before returning to the circulation tank. Since the refluxed impregnating agent may carry impurities such as agglomerates, glass fibers, and glass heads, it needs to be filtered through the return oil box. However, the current wire drawing process uses an oil return box installed on the top of the circulation tank. The filter is made of a 20-30 mesh filter screen. Since all impurities are filtered by the filter screen, larger impurities can easily clog the filter screen, requiring frequent cleaning and replacement. If the replacement is not timely, it is easy to cause pipe blockage or impurities to enter the oiler, affecting production.

[0003] CN201520773361.X discloses a coating agent return oil filtration device, comprising an oil applicator and a circulation tank; the circulation tank is connected to the oil applicator via an oil outlet pipe; the oil applicator is provided with an oil return pipe, which is connected to the circulation tank; a filter box is provided on the oil return pipe, and the oil return pipe is divided into two parts, wherein the oil return pipe located between the oil applicator and the filter box is a No. 1 oil return pipe, and the oil return pipe located between the circulation tank and the filter box is a No. 2 oil return pipe; the No. 1 oil return pipe is connected to the upper end of the filter box; the No. 2 oil return pipe is connected to the lower end of the filter box; a filter screen is provided in the middle of the filter box, which divides the filter box into two upper and lower cavities. This coating agent return oil filtration device utilizes the filtration within the filter box to filter the coating agent once, and then utilizes the provision of vertical plates to effectively precipitate and isolate small particles of impurities in the coating agent, ultimately achieving cleaning of the coating agent. However, the filter can be easily clogged by large impurities after only one filtration. Secondly, the fixed position of the vertical plate and the filter plate cannot be well used for sedimentation and filtration.

[0004] The technical problem to be solved by the utility model is: how to improve the filtering effect of the backflow of the wetting agent and facilitate the staff to clean the filtering unit. Utility Model Content

[0005] The main purpose of this utility model is to provide an infiltrant return oil filtration device that filters large impurities through a primary filter unit and then filters small impurities through a secondary filter unit. Furthermore, the first filter plate of the primary filter unit is positioned upwardly and obliquely, allowing large impurities to partially fall to the side of the baffle, thereby improving the filtration effect and the service life of the filter plate. Furthermore, by providing a cleaning module in the primary filter unit, it is easier for workers to clean the first filter plate, reducing their labor intensity.

[0006] To achieve the above objectives, the technical solutions adopted in this application are:

[0007] An impregnating agent return oil filter device comprises an oiling box, a circulation tank, a primary filter unit for filtering large impurities, and a secondary filter unit for filtering small impurities; the oiling box is in communication with the circulation tank; the oiling box is in communication with the primary filter unit; the primary filter unit is in communication with the secondary filter unit; the secondary filter unit is in communication with the circulation tank;

[0008] The primary filtration unit includes a first shell, a first filter plate, a collection box for collecting sediment and a cleaning module for cleaning the filter plate; a baffle is provided at the bottom of the first shell; the first filter plate is fixed obliquely upward in the first shell; the lower end of the first filter plate is detachably fixed to the baffle; the collection box and the filter plate are respectively located on both sides of the baffle.

[0009] Compared with the existing technology, this solution has the following beneficial effects:

[0010] The filtration device in this case filters large impurities through a primary filtration unit and then filters smaller impurities through a secondary filtration unit. This not only improves filtration efficiency but also prevents large impurities from clogging the pipes. Since the primary filtration unit primarily filters large impurities and requires relatively frequent cleaning, installing a cleaning module on the primary filtration unit reduces worker labor.

[0011] Secondly, the cleaning module is equipped with a scraper on the top and a nozzle on the side. The nozzle sprays water to soften the impurities on the first filter plate and remove some impurities, and then the scraper is used to scrape off the remaining impurities. The operation is simple, and cleaning can be completed with just a pull and a push, which greatly reduces the labor intensity of the staff. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0015] Example 1

[0016] refer to Figure 1-2 , a wetting agent return oil filtering device, comprising an oiling box 1, a circulation tank 2, a primary filter unit 3 for filtering large impurities, and a secondary filter unit 4 for filtering small impurities; the oiling box 1 is connected to the circulation tank 2; the oiling box 1 is connected to the primary filter unit; the primary filter unit is connected to the secondary filter unit 4; the secondary filter unit 4 is connected to the circulation tank 2;

[0017] The primary filtration unit includes a first shell 31, a first filter plate 32, a collection box 33 for collecting sediment and a cleaning module 34 for cleaning the filter plate; a baffle 35 is provided at the bottom of the first shell 31; the first filter plate 32 is fixed obliquely upward in the first shell 31; the lower end of the first filter plate 32 is detachably fixed to the baffle 35; the collection box 33 and the filter plate are respectively located on both sides of the baffle 35.

[0018] In this embodiment, the specific working process of the filtering device is as follows: the wetting agent in the circulation tank 2 is transported to the oiling box 1, and the excess wetting agent in the oiling box 1 is returned to the primary filter unit, and the primary filter unit filters the large impurities in the wetting agent, and then transports the wetting agent to the secondary filter unit 4, and the secondary filter unit 4 filters the small impurities in the wetting agent again. After the filtration is completed, the wetting agent returns to the circulation tank 2.

[0019] It should be noted that the first-level filter unit is arranged near the oiling box 1 to filter and intercept large impurities at the source to prevent large impurities from accumulating in the remaining pipes and causing pipe blockage, or large impurities from being blocked in the second-level filter unit 4, causing the second-level filter unit 4 to need to be replaced frequently.

[0020] Moreover, the first filter plate 32 is tiltedly arranged in the first shell 31, and the lower end of the first filter plate 32 is fixed on the baffle 35. The purpose of the tilted arrangement of the first filter plate 32 is not only to form an overhead area to prevent impurities from clogging the outlet, but also to allow some impurities adhering to the first filter plate 32 to slide along the surface of the first filter plate 32 into the collection box 33 for precipitation, thereby increasing the service life of the first filter plate 32.

[0021] Secondly, because the primary filter unit is used to filter large impurities, it needs to be cleaned more frequently. Therefore, a cleaning module 34 is provided on the primary filter unit. Staff only need to regularly clean the collection box 33, pull the first filter plate 32 through the cleaning module 34, and then return the first filter plate 32 to its original position to complete the cleaning process, effectively reducing staff workload.

[0022] Preferably, the first housing 31 is provided with an oil inlet 36 and an oil outlet 37 ; the oil inlet 36 is located above the collecting box 33 ; the oil outlet 37 is located below the first filter plate 32 .

[0023] In this embodiment, the infiltrant enters through the oil inlet 36. Some of the infiltrant falls directly onto the first filter plate 32, while some falls into the collection box 33. Due to impact and gravity, some impurities on the first filter plate 32 fall into the collection box 33. However, the infiltrant in the collection box 33 is less impacted, and the impurities gradually settle there, thus completing the impurity collection of the primary filter unit.

[0024] Preferably, the cleaning module 34 includes a cleaning shell 341; the cleaning shell 341 is detachably fixed to the side of the outer shell close to the first filter plate 32; the top of the cleaning shell 341 is provided with a scraper 342 for cleaning the surface of the first filter plate 32; the side of the cleaning shell 341 is provided with a water spray pipe 343; the first filter plate 32 is provided with a handle 321; the cleaning shell 341 is provided with a through hole; the free end of the handle 321 passes through the through hole and is fixed to the side of the cleaning shell 341.

[0025] In this embodiment, the specific working process of the cleaning module 34 is as follows: the staff pulls the handle 321 to separate the first filter plate 32 from the first shell 31. During this process, the water spray pipe 343 sprays water at the first filter plate 32. The scraper 342 is set close to the primary filter unit but does not contact the side of the cleaning shell 341. The scraper 342 scrapes impurities on the first filter plate 32. However, after the first filter plate 32 is completely separated from the first shell 31, the impurities on the scraper 342 will fall to the bottom of the cleaning shell 341. After pulling it out, the first filter plate 32 can be pushed back. During the pushing process, the scraper 342 scrapes the first filter plate 32 again. Through the two scraping operations of pulling and pushing, and in conjunction with the water spray pipe 343, the first filter plate 32 can be completely cleaned, thereby improving the cleaning effect, simplifying the operation, and reducing the workload of the staff.

[0026] Preferably, a collecting pipe 344 is provided at the bottom of the cleaning housing 341 .

[0027] In this embodiment, the collection pipe 344 collects impurities that fall to the bottom of the cleaning shell 341 , and the staff does not need to clean the cleaning shell 341 , further reducing the workload of the staff.

[0028] Preferably, the scraper 342 is made of rubber or plastic. The scraper 342 is preferably made of rubber.

[0029] Preferably, the secondary filter unit 4 includes a second housing 41 and a second filter plate 42 ; the second filter plate 42 is fixed in the second housing 41 .

[0030] In this embodiment, after the large impurities are filtered out by the primary filter unit, the secondary filter unit 4 only needs to be designed normally. Since the primary filter unit is added, the cleaning frequency of the second filter plate 42 can also be appropriately reduced, from once every 12 hours at the beginning to once every 24 hours.

[0031] Preferably, the mesh number of the first filter plate 32 is smaller than the mesh number of the second filter plate 42 .

[0032] Preferably, there are multiple primary filter units; the oiling box 1 is connected to the multiple primary filter units respectively; and the multiple primary filter units are all connected to the secondary filter unit 4 .

[0033] In this embodiment, multiple primary filter units are used for filtration. When one of them needs to be cleaned, it is only necessary to close the corresponding valve without affecting the overall production.

[0034] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
