Description

 The present invention relates to automatic filtering and bottling of filtered liquids and can be used in various fields of industry, including urban and rural conditions for filtering drinking water.

 It is known "Device for continuous automatic filtering of liquids", patent N 2069074, class B 01 D 29/60, 35/12, priority from 12/27/93, containing a vacuum filter with an upper chamber and a filtrate chamber separated by a mesh partition with filter elements . As the latter can be filter cloth, paper, etc.

 An additional pipeline is mounted vertically in the tank, which is filled with filtered liquid, and an additional pipe is connected that is connected in its upper part by a pipe to the passive nozzle of the ejector. Compressed air is supplied to its active nozzle from the compressed air line. The drain pipe of the vacuum filter is connected by a pipe to the upper part of the vertical pipe. The fluid to be filtered is fed into the upper chamber of the vacuum filter through a pipe. A float valve is installed in the upper chamber to prevent overflow. In the drain tank there is a pipeline for draining the filtered liquid from it, the pipelines are equipped with control valves.

 The lower end of the drain pipe of the vacuum filter is installed above the liquid level, which the suction force of the ejector can raise in it. The lower end of the additional pipeline is immersed in a container with filtered fluid.

 The device operates as follows. Before starting work, close the taps in the vertical pipe and the drain pipe of the vacuum filter. A tap is opened in the pipeline through which liquid is introduced into the upper chamber of the vacuum filter. Then open the tap in the compressed air line. Compressed air passing through the ejector will create a vacuum in the vertical pipe and the filtrate chamber.

 Initially, filtering is carried out using a vacuum filter, after filling the filtrate chamber with filtered liquid, it is manually drained using a tap in the drain pipe into a drain tank. After filling it, they switch to continuous automatic filtering. To do this, close the tap in the drain pipe and open the tap in a vertical pipe. Under the influence of atmospheric pressure, the liquid from the discharge tank fills the vertical pipeline to a certain height. This lift height depends on the suction force of the ejector and the density of the liquid. Filtered liquid from the vacuum filtrate chamber installed above the drain tank will merge into the upper part of the vertical pipeline, from it into the drain tank, and from it will be discharged through the pipeline for its intended purpose.

 Adjusting the operation of the device is carried out using cranes. After finishing work, it is necessary to close the taps in the pipelines. The choice of materials from which the device is made is determined by the properties of the liquids to be filtered. Such materials may be: vinyl plastic, polyethylene, ftoroplast, etc.

 The disadvantages of the device include: not everywhere there is compressed air that is used to operate the ejector, and with it it is impossible to obtain a vacuum close to zero, therefore, to obtain the maximum rise in liquid and filtration rate due to the greatest vacuum and atmospheric pressure.

 The issue of automatic spilling of filtered liquids has not been resolved; due to a worker’s oversight, it is possible to overfill it in a discharge tank.

 The closest in technical essence, selected as a prototype, is a "Device for continuous automatic filtering of liquids", patent N 2106178, class B 01 D 29/60, 37/04, priority from 03/31/97.

 This device contains a filter with a suction hose mounted on a nozzle of a vertical additional pipeline, which is installed above the liquid level, which can be lifted by the suction force of the ejector, connected through its passive nozzle to the upper part of this additional pipeline, and its lower part to the tank with filtered liquid. The tank has a pipeline for draining filtered fluid from it. And compressed air is supplied to the ejector through the compressed air line. All pipelines have control valves.

 The device operates as follows. Before starting work, close the tap in the auxiliary pipe and open it in the compressed air line. Compressed air, passing through the ejector, creates a vacuum, vacuum, in an additional pipeline, with the help of which liquid under atmospheric pressure, passing through the filter, will merge into this pipeline. After filling it with filtered liquid, open the tap, pour it into a drain tank and switch to automatic operation. Under the influence of atmospheric pressure, liquid from the drain tank fills an additional pipeline to a certain height. This height depends on the suction force of the ejector and the density of the liquid. And the liquid from the tank installed above this tank, passing through the filter, will be drained into an additional pipeline, and from it - into the tank from which it can be drained through the filling pipeline.

 The disadvantages of the device include: not everywhere there is compressed air that is used to operate the ejector, and with it it is impossible to obtain a vacuum close to zero, therefore, to obtain the maximum rise in liquid and filtration rate due to the greatest vacuum and atmospheric pressure.

 The issue of automatic spilling of filtered liquids has not been resolved; due to a worker’s oversight, it is possible to overfill it in a discharge tank.

 This goal is achieved by the fact that the upper part of the additional pipeline is connected by a pipeline to a mechanical vacuum pump with an electric drive, and on the lid of the tank, to drain the filtered liquid into it, a housing is fixed, and the lower end of its rod, which is held in it by means of screwed onto it nuts, where a float with an adjusting weight is movably mounted between the two stops, with the ability to turn off the final electrical switch mounted on the housing cover in the upper position using a float a permanent magnet mounted and fixed inside the housing opposite the stem stop.

 This allows you to get the greatest vacuum in the upper part of the additional pipeline and due to it to get the maximum rise in fluid and filtering speed due to the greatest vacuum and atmospheric pressure.

 A body fixed to the lid of the tank to drain the filtered liquid into it, and the lower end of its rod, which is held in it with the help of nuts screwed on it, is installed in the tank, where a floating float with an adjusting weight is mounted between the two stops on it, with the ability to turn off in the upper position the final electrical switch, mounted on the housing cover, using a float, a permanent magnet mounted and fixed inside the housing opposite the rod stop, automates the spill of the filter Rowan fluid and prevent it from overflowing the tank to drain.

 In this, the author sees the novelty and significant differences of his proposed device for automatic filtering and spilling of filtered fluid.

 The drawing shows a General view of the device. It contains a filter 1, an additional pipe 2 with an intake pipe 3 installed above the liquid level, which can raise a vacuum in it, connected through a filter 1 and a pipe 4 with a container 5 and a liquid 6, which must be filtered. And its lower part is connected by a pipeline 7 with a capacity of 8 for draining the filtered liquid into it.

 The upper part of the additional pipeline 2 is connected by a pipe 9 to a mechanical vacuum pump 10 with an electric drive 11 with the control buttons "Start" 12 and "Stop" 13.

 A housing 15 is fixed on the lid 14 of the container 8, a rod 16 is installed in it, which is held in it with the help of adjusting nuts 17, and a float 19 with an adjusting weight 20 is mounted movably between its stops 18 in the container 8.

 In the case 15, a permanent magnet 22 is fixed by a cover 21, opposite the stop 23 of the rod 16, and in its cover 24 there is a final electric switch 25 connected by electric wires 26 to the “Start” 12 and “Stop” buttons 13. The cover 24 is fixed to the case by 15 screws, which are not conventionally shown in the drawing, as well as the screws that secure the housing 15 to the tank 8, on which there are pipelines 27 for pouring filtered liquids, in the pipelines there are control valves 28, and in the cover 14 of the tank 8 there is a hole 29 for connecting it with the atmosphere .

 The operation of the device. Close the valve 28 in the pipeline 7 and use the "Start" button 12 to start the electric motor 11. Then the mechanical vacuum pump 10 pumps the air out of the additional pipeline 2 and due to the pressure drop: the vacuum in it and the atmosphere in it from the tank 5, passing through filter 1, the filtered liquid will come 6. After filling the liquid 6 of the additional pipe 2, open the valve 28 in the pipe 7 and drain it into the container 8 and switch to the automatic mode of filtering and pouring the filtered liquid.

 If the container 8 is filled with filtered liquid 6, then its float 19 will float up and, acting on the stop 18, will raise the rod 16 to the upper position, which will turn off the end electric switch 25 with its upper end 30, stop the operation of the electric motor 11 and the operation of the device will be automatically stopped . And the rod 16 will hold in this position a permanent magnet 22 by acting on the emphasis 23.

 When draining the liquid 6 from the tank 8, its float 19 will go down and, acting on the stop 18, will lower the rod 16 to the lower position and the cycle of the device will resume.

 After finishing work, turn off the electric motor 10 using the Stop button 13 and close the taps 27.

 Adjusting the operation of the device is carried out using the adjusting weights 19, nuts 16 and cranes 27.

 The material of the device depends on the chemical properties of the liquids that need to be filtered.
