Description

TECHNICAL FIELD

[0001] The utility model relates to the raw material production technology field of neutral glass glue, especially relates to a raw material filtering device for neutral glass glue production. BACKGROUND

[0002] Sodium silicate is also called soda ash, which is an inorganic substance with the chemical formula Na2O·nSiO2. Sodium silicate is the main film-forming material of neutral glass glue and plays a key role in bonding. Sodium silicate is easily soluble in water and has viscosity, which plays a core role in neutral glass glue.

[0003] A filtering device for liquid sodium silicate production (authorized publication number CN217490005U) is disclosed in a Chinese patent. The utility model has the advantages that the scraper can remove the adhered sodium silicate on the filter cylinder during rotation; the cooperation of the positioning mechanism and the positioning block reduces deformation and position deviation of the filter cylinder during height rotation, and improves work efficiency.

[0004] According to the above reference case, the device can spin the filter cylinder to throw out the liquid sodium silicate, and use the scraper to remove the liquid sodium silicate adhered to the outside of the filter cylinder. However, the liquid sodium silicate is easily adhered to the inner wall of the collection bin used to contain the filter cylinder during the process of throwing out the filter cylinder. The above device cannot effectively clean the residual liquid sodium silicate on the inner wall of the collection bin, which reduces the effective collection rate of liquid sodium silicate. UTILITY MODEL CONTENTS

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art. Therefore, the purpose of the utility model is to provide a raw material filtering device for neutral glass glue production to solve the problem that the inner wall of the collection bin is easy to leave residual liquid sodium silicate, which reduces the effective collection rate of liquid sodium silicate.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The embodiment of the application provides a raw material filtering device for neutral glass glue production, which comprises: a mounting cylinder, a feed pipe and a discharge pipe are respectively installed at the top and bottom ends of the mounting cylinder, a filter cylinder is rotatably connected inside the mounting cylinder, and the bottom of the filter cylinder penetrates to the outside of the mounting cylinder; a cleaning device is installed inside the mounting cylinder.

[0008] In some embodiments, the cleaning device comprises a rotating ring connected to the inner top wall of the installation cylinder, the bottom of the rotating ring is fixedly connected with a scraper, the two ends of the scraper are in contact with the vertical inner wall of the installation cylinder and the vertical outer wall of the filter cylinder respectively, and the bottom of the scraper is in contact with the inner bottom wall of the installation cylinder. The cleaning device can actively scrape the residual liquid sodium silicate between the installation cylinder and the filter cylinder, guide the liquid sodium silicate to the discharge pipe, reduce the residence rate of the liquid sodium silicate in the installation cylinder, improve the effective collection rate of the liquid sodium silicate, and drive the filter cylinder and the scraper to rotate in opposite directions, which can accelerate the separation rate of the liquid sodium silicate and impurities, and accelerate the scraping rate of the liquid sodium silicate on the vertical outer wall of the filter cylinder, further improving the discharge rate of the liquid sodium silicate.

[0009] In some embodiments, the inner bottom wall of the installation cylinder is convex to the direction of the feeding pipe and forms a circular truncated cone slope, and the lowest part of the discharge pipe is communicated with the lowest part of the inner bottom wall of the installation cylinder, which can guide the liquid sodium silicate to the discharge pipe, further reducing the residence rate of the liquid sodium silicate in the installation cylinder.

[0010] In some embodiments, the bottom of the scraper is inclined and fitted with the inner bottom wall of the installation cylinder, and the cross-sectional size of the bottom of the scraper is the same as that of the inner bottom wall of the installation cylinder, which can ensure that the scraper can always scrape the liquid sodium silicate on the inner bottom wall of the installation cylinder, improving the scraping effect of the liquid sodium silicate.

[0011] In some embodiments, the number of scrapers is not less than five, and the scrapers are distributed in a ring shape around the axis of the rotating ring between the installation cylinder and the filter cylinder, which can accelerate the scraping of the liquid sodium silicate, further improving the discharge rate of the liquid sodium silicate.

[0012] In some embodiments, the vertical cross-sectional shape of the scraper parallel to the axis of the filter cylinder is an isosceles triangle, and the cross-sectional diameter of the scraper gradually narrows from top to bottom, which can reduce the probability of liquid sodium silicate remaining on the surface of the scraper, further reducing the residence rate of the liquid sodium silicate in the installation cylinder.

[0013] In some embodiments, the cleaning device further comprises a servo motor fixedly connected to the top of the installation cylinder, the end of the output shaft of the servo motor is fixedly connected with a gear, the surface of the gear is engaged with an inner ring gear fixedly connected with the rotating ring, the surface of the gear is engaged with an outer ring gear, and the outer ring gear is fixedly connected to the surface of the filter cylinder.

[0014] In some embodiments, the inner top wall of the mounting cylinder is provided with an annular cavity, the filter cylinder and the rotating ring are both rotationally connected to the inside of the annular cavity, and the gear, the inner ring gear and the outer ring gear are all arranged inside the annular cavity, so that the gear, the inner ring gear and the outer ring gear are separated from the splashed liquid sodium silicate, and normal operation of the gear, the inner ring gear and the outer ring gear can be ensured.

[0015] Compared with the prior art, the utility model at least has the following beneficial effects:

[0016] The cleaning device can actively scrape off the residual liquid sodium silicate between the mounting cylinder and the filter cylinder and guide the liquid sodium silicate to the discharge pipe, which can reduce the residence rate of the liquid sodium silicate in the mounting cylinder, improve the effective collection rate of the liquid sodium silicate, and drive the filter cylinder and the scraper to rotate in opposite directions, which can accelerate the separation rate of the liquid sodium silicate and impurities and the scraping rate of the liquid sodium silicate on the vertical outer wall of the filter cylinder by the scraper, and further improve the discharge rate of the liquid sodium silicate.
