Description

The technical solution relates to mechanical engineering and can be used in pipeline networks for pumping oil to clean it from various impurities and dirt.

A technical solution is known [1], in which the device for cleaning the filter from dirt in the interface between the intermediate bottom and the sediment chamber has a recess and is configured to fill it with the supplied washing liquid from the inside or the outside.

Such a device is designed to clean filters of relatively low productivity, since with a large throughput power, the filter is quickly clogged, and it is difficult to clean it properly.

A technical solution is known [2], in which the filter cleaning device has a source of ultrasonic vibrations and sealing elements. The sealing elements create a closed space, separated from the volume filled with liquid. In addition, openings for supplying and removing liquid for cleaning are made in the sealing elements. This device is partially in contact with the surface to be cleaned. The source of ultrasonic vibrations is set so that the beam of ultrasonic vibrations is focused on the surface being cleaned. In addition, the distance from the source of ultrasonic vibrations to the surface being cleaned is adjustable.

The specified device is effective and has positive characteristics when filtering a product of low viscosity, that is

when the filter element does not stick. If the filtered product is viscous, then ultrasonic vibrations will not clean the surface of the filter.

It is also known a device [3] for washing dirt from a filtering surface, consisting of a drive and a cultivator. The latter is made in the form of a flat serrated inclined knife with an inclined shield located above it and vertical posts installed between the knife and the shield.

This device does not completely clean the filter element. After cleaning, a layer remains on the filter element, which will quickly grow during the filtering process.

In addition to the above disadvantages, these devices have common:

- constructive piling, howl devices are inside the filter housings;

- it is impossible to carry out effective control of the cleaning process, both quantitatively and qualitatively.

When filtering, for example, oil, the working pressure reaches 70 kgf / cm ² , which means that the holes must be well sealed. Currently, when transporting oil through pipelines, horizontal filters are used. They have a cylindrical body and a rotary bottom with a seal. A filter element is placed inside the housing, which is removed from the housing for washing. And they put it into the case with a tractor. This leads to time-consuming, inconvenient maintenance and oil spills. Service requires at least two people: a tractor driver and an operator.

To eliminate the shortcomings, the task was to create a structurally simple and cheap device for removing and installing the filter element in the filter housing.

To accomplish this task, taking into account the large dimensions of the filter element and its weight, the device has a frame on which the drive is mounted, and between the racks of the frame there is a shield in the form of a groove.

Unlike the known ones, the claimed device has two parallel guides for moving the filter element over the frame, along its length, mounted on the uprights, moreover, the guides are made of pipes, in which the pipe of a smaller diameter is placed, with the ability to move to different parties, the latter have final guides with clamps, in addition, to remove the filter element, it is connected with a flexible flexible drive, and for installing the filter element in the filter housing, the device is additionally equipped with a sense the body, which is driven by the drive, through flexible communication and a system of blocks.

These distinctive features are inextricably linked with the technical result, namely:

- above the frame, along its length, two parallel guides are fixed on the uprights. The guides are fixed to move the filter element for cleaning and install it after cleaning in the filter housing. Two rollers are installed on the filtering element on its sides, the profile of which describes a section of the pipe. The parallelism of the guides ensures trouble-free operation of the device, that is, the moving filter element does not come off the guides;

- guides made of pipes. This gives additional rigidity to the guides;

- pipes of smaller diameter are placed in the pipes, which ensures the compactness of the device as a whole, as well as their movement in different directions;

- pipes of smaller diameter have final guides with clamps. When removing and installing the filter element,

pipes of smaller diameter are pulled out from pipes of larger diameter and the end guides are inserted into pipes fixed in the filter housing. Thus, with the help of end guides, elongated guides are formed and are locked by clamps, preventing self-movement of pipes;

- the filter element is connected to the drive by a flexible connection, and for installing the filter element in the filter housing, the device is additionally equipped with a pusher. This ensures the movement of the filter element in two directions without additional mechanisms and piles;

- the pusher is driven by the drive, through flexible communication and a system of blocks. For movement in the figurative direction, that is, for installing the filter element in the filter housing, the same mechanism with flexible coupling is used. Communication is made on blocks with an arc of the side and the pusher is set in motion. Thus, the same mechanisms of the device are used to remove and install the filter element in the housing, which ensures a minimum of costs for the manufacture of the device.

The device is illustrated by drawings.

Figure 1 shows a device that extracts a filter element.

Figure 2 is a section along aa

A device for removing and installing the filter element 1 in the filter housing 2, consists of a frame 3 on which the drive 4 is mounted. Between the posts 5 of the frame 3, a shield is placed in the form of a groove 6, and on the posts 5, above the frame 3 along its length, are fixed two parallel guides for moving the filter element 1. The guides are made of pipes 7. in which the smaller diameter pipes 8 are placed. The pipes 8, smaller in diameter, have end guides 9 with clamps 10. To remove the filter element 1, the latter is connected to the actuator 4 by a flexible connection 11, and for install the filter element 1 in the housing 2

filter, the device is additionally equipped with a pusher 12, which is driven by a drive 4 by means of a flexible connection 11 and a system of blocks 13.

The device works this way.

To remove the filter element 1 open and take aside the cover (in Fig. Not shown) on the filter housing 2. Pipes 8, of smaller diameter, are pulled out from pipes of larger diameter and their final guides 9 are inserted into pipes fixed inside the filter housing 2 (not shown in FIG.). The extended pipes 8 are locked by the latches 10. Thus, elongated guides are created along which the filter element is moved, hooking it with a flexible connection with the drive 4. When removing the filter element 1 and washing it, all the dirt flows into the groove 6.

After cleaning the filter element from dirt, it is again installed in the filter housing. To do this, use a pusher installed between the drive and the filter element and connected to the drive by a flexible connection through a system of blocks. When tensioning the flexible connection, the pusher abuts against the front part and moves the filter element into the filter housing.

After installing the filter element in the housing, release the latches, divert pipes of a smaller diameter, and then the entire device.

The claimed technical solution is structurally simple, easy to maintain and is essential for the operation of oil pipelines.
