Description

Technical Field

[0001] This utility model belongs to the field of pipe sight glass cleaning technology, and specifically relates to a pipe sight glass with a magnetic cleaner. Background Technology

[0002] In petrochemical plants, numerous sight glasses are typically installed on circulating water pipelines. These sight glasses are used to observe the circulating water return flow from the outside. However, conventional pipeline sight glasses are fixed glass sight glasses. Due to the high levels of impurities and corrosive media in the circulating water of oil refineries and petrochemical plants, a layer of dirt accumulates on the glass of the pipeline sight glasses over time, making the glass opaque. To facilitate observation, it is necessary to stop the relevant pumps or switch to standby pumps before opening the pipeline sight glasses and cleaning the inner surface of the glass.

[0003] Currently, a technology for manually cleaning pipeline sight glasses has been used in production. This involves drilling holes in the sight glass, installing a cleaner or cleaning strip inside, and attaching a handle to the outside. The handle is connected to the cleaner or cleaning strip via a shaft. Manually rotating the handle from the outside rotates the cleaner or cleaning strip inside the sight glass, thus cleaning it. However, although theoretically the circulating water in petrochemical plants does not contain toxic, harmful, flammable, or explosive media, under long-term operating conditions, a considerable number of cooler leaks may occur, causing toxic, harmful, flammable, or explosive media to leak into the circulating water system. After prolonged use of the cleaning device, this could lead to leakage of toxic, harmful, or flammable / explosive media from the circulating water through the drilled holes in the sight glass, posing a certain safety risk. Utility Model Content

The purpose of this utility model and the solution to its technical problems are achieved through the following technical solution. According to this utility model, a pipe sight glass with a magnetic cleaner includes a pipe, a sight glass mounted on the pipe, and a cleaning device. A support rod is provided on the inner wall of the pipe, and a pin is vertically arranged at the end of the support rod. The cleaning device includes an outer cleaner and an inner cleaner respectively located on both sides of the sight glass. Both the outer and inner cleaners include a housing, and a cleaning brush is provided on the side of the housing facing the sight glass, which contacts the surface of the sight glass. An outer magnetic material is provided inside the housing of the outer cleaner, and an inner magnetic material is provided inside the housing of the inner cleaner. The outer and inner magnetic materials have opposite magnetic properties, causing the outer and inner cleaners to adhere to the sight glass. The inner cleaner is located between the support rod and the sight glass. The housing of the inner cleaner away from the cleaning brush contacts the support rod, and the housing of the inner cleaner is rotatably connected to the pin.

[0005] Furthermore, the sight glass is fixed to the pipeline through the cooperation of the sight glass flange and the fastening flange.

[0006] Furthermore, the sight glass has annular gaskets on both sides to contact the sight glass flange and the fastening flange respectively.

[0007] Furthermore, the external cleaner has a handle on its housing.

[0008] Furthermore, the housing of the internal cleaner is provided with a shaft hole, into which the shaft pin is inserted.

[0009] Furthermore, the support rod is fixed to the inner wall of the pipe via a fixing seat.

[0010] Furthermore, the cleaning brush is detachably connected to the housing.

[0011] In summary, this utility model has the following advantages: By incorporating magnetically attached inner and outer cleaners, the outer cleaner drives the inner cleaner to clean the sight glass. This allows for the regular removal of dirt from the pipe sight glass, keeping it clean and facilitating observation of water flow within the pipe. The inner cleaner is magnetically driven by the outer cleaner, eliminating the need for drilling holes in the sight glass and avoiding the risk of leakage of toxic, flammable, or explosive media. Cleaning does not require stopping or switching equipment, avoiding unnecessary impact on production. The inner cleaner's rotation is guided by a pivot pin, and the support rod provides stability, ensuring that the magnetically driven inner cleaner does not shift or deflect, thus providing a stable cleaning effect.

[0012] The above description is merely an overview of the technical solution of this utility model.

[0014] Figure 2 for Figure 1 Top view. Detailed Implementation

[0015] The technical solution of this utility model will be further described below with reference to the accompanying drawings and preferred embodiments.

[0016] Please see Figure 1 , Figure 2A pipe sight glass with a magnetic cleaner includes a pipe 1. A support rod 2 is connected to the inner wall of the pipe 1 via a fixed seat. A pin 31 is vertically arranged at the end of the support rod 2. A pipe joint is protruding on the pipe 1. A sight glass 16 is installed at the pipe joint. The sight glass 16 is fixed to the pipe 1 by the cooperation of a sight glass flange 13 and a fastening flange 14. Annular gaskets 15 are provided on both sides of the sight glass 16 to contact the sight glass flange 13 and the fastening flange 14 respectively, which can prevent the flange from directly contacting the sight glass 16 and reduce wear on the sight glass 16. At the same time, the aforementioned support rod 2 is also installed at the pipe joint (on the pipe wall perpendicular to the sight glass 16).

[0017] A cleaning device 4 is provided on the sight glass 16. The cleaning device 4 includes an outer cleaner and an inner cleaner respectively located on both sides of the sight glass 16. Both the outer cleaner and the inner cleaner include a housing, and a cleaning brush 41 is provided on the side of the housing facing the sight glass 16, which contacts the surface of the sight glass 16. The cleaning brush 41 is detachably connected to the housing (e.g., fixed to the housing by bolts) to facilitate the replacement of the cleaning brush 41. The housing of the outer cleaner contains an outer magnetic material 43 (e.g., a magnet, in which multiple magnets can be evenly distributed to increase the magnetic attraction; the magnets can be fixed to the housing by binding or bolts, etc.). The housing of the inner cleaner contains an inner magnetic material 44 (which is connected to the outer magnetic material). The materials, placement, and quantity of the outer and inner magnetic materials 43 are identical, and the magnetic properties of the outer and inner magnetic materials 44 are opposite, so that the outer and inner cleaners are attracted to the sight glass 16. When the outer cleaner is moved, the inner cleaner can be driven to move. At the same time, the outer cleaner is provided with a handle 42 on its housing, which can be used to move the outer cleaner. With the help of the aforementioned technical features, dirt on the sight glass 16 of the pipe 1 can be cleaned regularly, keeping the sight glass 16 clean and facilitating the observation of the water flow in the pipe 1. Meanwhile, the inner cleaner is driven by the magnetic attraction of the outer cleaner, eliminating the need to drill holes in the glass of the sight glass 16 and avoiding the risk of leakage of toxic, flammable, and explosive media.

[0018] Furthermore, the inner cleaner is located between the support rod 2 and the sight glass 16. The housing of the inner cleaner at the end away from the cleaning brush 41 contacts the support rod 2, and the housing of the inner cleaner is provided with a shaft hole 46. The shaft pin 31 is inserted into the shaft hole 46 so that the housing of the inner cleaner is rotatably connected to the shaft pin 31. With the aforementioned technical features, the inner cleaner is guided to rotate by the shaft pin 31, and the support rod 2 provides support, so that the inner cleaner does not deviate or turn when driven by magnetic attraction, thereby providing a stable cleaning effect.

[0019] Working process: When the outer cleaner is held against the eyeglass 16, the outer cleaner can attract the inner magnetic material 44 in the inner cleaner through the outer magnetic material 43, so that the cleaning brushes 41 of the two cleaners are in close contact with the eyeglass 16. When the outer cleaner is rotated or dragged, the inner cleaner moves synchronously due to the magnetic attraction, thereby cleaning the eyeglass 16.

[0020] In other embodiments of this utility model, pipe joints can be symmetrically arranged on both sides of the pipe 1, and sight glasses 16 are provided at both pipe joints. The two sight glasses 16 can observe the internal condition of the pipe 1 from different directions, which can ensure the accuracy of the observation results. The upper and lower sight glasses 16 are equipped with internal cleaners. The ends of the two internal cleaners away from the shaft pin 31 are connected by a connecting rod. When the upper internal cleaner is driven by the external cleaner, it can simultaneously drive the lower internal cleaner to perform cleaning work, thereby achieving the purpose of one external cleaner driving two internal cleaners to perform cleaning.

[0021] The above description is merely a preferred embodiment of this utility model. Any simple modifications, equivalent changes, and alterations made by those skilled in the art to the above embodiments based on the technical essence of this utility model without departing from the scope of the technical solution of this utility model shall still fall within the scope of the technical solution of this utility model.
