Abstract
Description
Technical Field
[0001] This invention relates to the field of filtration device technology, and in particular to an industrial white oil filter. Background Technology
[0002] When industrial white oil is stored for a long time, the wax, asphalt, and other chemical substances it contains separate out during the settling process, forming sediment. When this impurity-laden white oil is used in machinery, it accelerates wear and tear. Therefore, white oil needs to be filtered before use to remove impurities and improve its cleanliness. Currently, common white oil filtration mechanisms include centrifugal filtration and screen settling filtration. Centrifugal filtration is highly efficient, but its structure is more complex, resulting in higher equipment costs. Screen settling filtration is cheaper, but impurities can accumulate on the screen, leading to poor filtration and consequently affecting production efficiency.
[0003] Therefore, an industrial white oil filter with patent number CN222033766U was developed. Although this device solves the above problems, it has the following defects: the scraper is in contact with the top surface of the filter screen for a long time, which will block the top part of the aperture and thus affect its filtration efficiency. At the same time, it is difficult to remove the impurities on the top surface of the filter screen by simply rotating the scraper, thus affecting the cleaning efficiency and effect of the top impurities. Summary of the Invention
[0004] The purpose of this invention is to provide an industrial white oil filter.
[0005] The technical problem of this invention is mainly solved by the following technical solution:
[0006] An industrial white oil filter includes a tank body with a support ring inside. A slag discharge pipe is provided on the side wall of the tank body above the support ring. An inverted umbrella-shaped filter screen is also provided on the support ring. An inverted V-shaped scraper is provided above the filter screen and is driven by a motor. An umbrella-shaped flow guide hood is provided below the filter screen. The top of the flow guide hood is fixedly connected to the bottom of the filter screen. A sleeve is provided at the bottom of the flow guide hood. A vertical pipe extending into the sleeve is provided on the bottom wall of the tank body. An electric push rod connected to the bottom of the flow guide hood is provided inside the vertical pipe.
[0007] Preferably, the tank body consists of an upper shell and a lower shell, and the slag discharge pipe is disposed on the side wall of the lower shell.
[0008] Preferably, the tank body is provided with an outlet pipe at the bottom and an inlet pipe at the top, and the top wall of the tank body is also provided with a recess for accommodating the motor.
[0009] Preferably, the output shaft of the motor is fixedly connected to the middle of the top of the scraper, and the output shaft of the motor is also provided with fan blades.
[0010] Preferably, the edge of the filter screen is fixed to the top surface of the support ring.
[0011] Preferably, the scraper and the top inclined surface corresponding to the guide shield are arranged in parallel.
[0012] The beneficial effects of this invention are as follows: In this invention, since neither the scraper nor the guide shroud comes into contact with the filter screen when filtering the liquid, they will not clog the filter screen pores, thus not affecting the filtration efficiency. When scraping off and cleaning the impurities on the top of the filter screen, the side wall of the flipped filter screen is taut under the pressure of the guide shroud side wall, which facilitates the scraper to fully contact the top surface of the filter screen to scrape off and clean the impurities on the top surface. At the same time, the electric push rod drives the filter screen to flip up and down to change its shape, so that the impurities on the top surface are easily separated from the side wall under the influence of the filter screen deformation, thus facilitating the separation of impurities from the filter screen, or facilitating the separation of impurities scraped off by the scraper from the filter screen. Finally, the impurities are discharged from the top slope of the filter screen after deformation to its edge. Attached Figure Description

[0015] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.
[0016] An industrial white oil filter includes a tank body 1, a support ring 2 inside the tank body 1, a slag discharge pipe 3 on the side wall of the tank body 1 above the support ring 2, and an inverted umbrella-shaped filter screen 4 on the support ring 2, wherein the edge of the filter screen 4 is fixed to the top surface of the support ring 2. In this embodiment, the filter screen 4 is made of stainless steel.
[0017] A V-shaped scraper 5 with an inverted arrangement is provided above the filter screen 4. The scraper 5 is driven by a motor 6. A flow guide 7 in the shape of an umbrella is also provided below the filter screen 4. The top of the flow guide 7 is fixedly connected to the bottom of the filter screen 4. The scraper 5 and the top inclined surface of the flow guide 7 are parallel to each other. A sleeve 8 is provided at the bottom of the flow guide 7. A vertical pipe 9 extending into the sleeve 8 is provided on the bottom wall of the tank body 1. An electric push rod 10 connected to the bottom of the flow guide 7 is provided in the vertical pipe 9.
[0018] In this embodiment, the tank body 1 is composed of an upper shell and a lower shell, and the slag discharge pipe 3 is arranged on the side wall of the lower shell.
[0019] like Figure 1 As shown, the tank body 1 is provided with an outlet pipe 11 at the bottom and an inlet pipe 12 at the top. The top wall of the tank body 1 is also provided with a recess for accommodating the motor 6.
[0020] like Figure 1 As shown, the output shaft of the motor 6 is fixedly connected to the top middle of the scraper 5, and a fan blade 13 is also provided on the output shaft of the motor 6.
[0021] The method of using this invention is as follows: Industrial white oil is introduced into the tank 1 above the filter screen 4 through the inlet pipe 12. The oil is filtered by the filter screen 4, and the filtered liquid falls downwards onto the guide shroud 7 and flows along the top slope of the guide shroud 7 to the edge of the guide shroud 7. Then, it flows into the bottom of the tank 1 through the gap between the edge of the guide shroud 7 and the side wall of the tank 1 and accumulates. At this time, the guide shroud 7 can act as a shield to prevent the liquid falling from a height from coming into contact with the liquid accumulated at the bottom of the tank 1 and causing a large amount of splashing, which then comes into contact with the filter screen 4 or the impurities above it.
[0022] When it is necessary to clean the impurities on the top of the filter screen 4, the filtered oil at the bottom of the tank 1 can be discharged. During cleaning, the electric push rod 10 drives the guide shroud 7 to move upward. The guide shroud 7 drives the vertical pipe 9 on the sleeve 8 to slide upward, and the guide shroud 7 pushes the filter screen 4 to deform, that is, flips the end face of the filter screen 4 so that it forms an umbrella-shaped structure with the opening facing downward. Due to the pressure of the side wall of the filter shroud 7, the filter shroud 7 can straighten the filter screen 4 and stick it tightly to its top surface. At this time, the filter shroud 7 can support and shape the soft and deformable filter screen 4. After flipping the filter screen 4, its... The top surface of the filter screen 4 is in contact with the bottom surface of the scraper 5. At this time, the scraper 5 can be driven to rotate by the motor 6, so that the scraper 5 can scrape off and clean the impurities on the top surface of the filter screen 4. The cleaned impurities flow along the top slope of the filter screen 4 to its top edge, and can then be discharged through the corresponding open slag discharge pipe 3. At the same time, the motor 6 can also drive the fan blade 13 to rotate to generate airflow, so that the airflow acts on the top surface of the filter screen 4. Firstly, it can indirectly separate the impurities on the top of the filter screen 4 from the filter screen 4 under the influence of the airflow. Secondly, it can also play a certain role in removing water from the impurities to facilitate the cleaning work.
[0023] In the above process, the filter screen 4 can also be driven by the electric push rod 10 to flip up and down to change its shape, so that the impurities on the top surface of the filter screen 4 are easily separated from its side wall under the influence of the deformation of the filter screen 4, thus facilitating the separation of impurities from the filter screen 4, or making it easier for the impurities scraped off by the scraper 5 to be separated from the filter screen 4. Finally, the impurities are discharged from the top slope of the filter screen 4 after deformation to its edge. In the above process, since the scraper 5 and the guide shroud 7 do not contact the filter screen 4 when the filter screen 4 is filtering the liquid, they will not block the aperture of the filter screen 4, so it will not affect its filtration efficiency. When scraping off and cleaning the impurities on the top of the filter screen 4, the side wall of the flipped filter screen 4 is in a taut state under the pressure of the side wall of the guide shroud 7, which also makes it easier for the scraper 5 to fully contact the top surface of the filter screen 4 to scrape off and clean the impurities on its top surface.
[0024] The present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
