Description

The claimed utility model relates to the field of railway technology, namely to devices for the bottom discharge of high-viscosity and frozen products from railway tanks under conditions when the discharge of the product without preheating is difficult or impossible.

Known selected as a prototype nozzle for a hydromonitor of a device for lower drainage of a container (RF patent for invention No. 2403984, IPC B05B1 / 14, B67D7 / 04, B67D99 / 00, publ. 20.11.2010), containing a hollow cylindrical body with nozzles located around the circumference, and with a stop fixed on the end of the body, made with the possibility of ensuring the location of the outlet openings of the nozzles not lower than the level of the opening of the drain valve of the container when the hydraulic monitor is fully raised with an emphasis on the plate of the fully open drain valve, and the housing has openings on the side opposite to the end with a stop, providing outflow product at an angle to the axis of the body 60 ° or less.

The known technical solution allows, during circulation heating and (or) discharge of the product from the railway tank car, to provide the supply of hot product to the zone of selection of the cold product from the tank car to ensure its fluidity through the suction pipeline.

It is also known from the description of the prototype that, in addition to the horizontal outflow of the hot product, part of the flow of the hot product is fed in small jets at an angle from the horizontal downward to the walls of the tank drain device, warming it up to prevent the cold product from sticking to the inner surface of the drain device walls. This supply of the product is carried out through the holes in the body on the side opposite to the end with the stop, which ensure the outflow of the product at an angle to the body axis of 60 ° or less.

However, since these holes in the body of the prototype nozzle have a constant diameter, without the possibility of adjusting it, there is no possibility of controlling the impact force of the liquid flow (the effect of the spray on the irrigation surface). A change in the impact force of the liquid flow through the holes, for example, its increase, is necessary to prevent the sealing of the drain line by the solid phase of the discharged viscous product or to clean the walls of the drain line. A decrease in the impact force of the flow through the holes is expedient for redistributing the impact force to the nozzles directed inside the tank for more efficient heating of the cargo.

It is known (for example, publication on the Internet: https://www.sprayrus.ru/Assets/RU/ssco_cat70m-ru_a.pdf) that the total theoretical impact force I depends on the fluid flow rate through the section and is determined by the formula:

, гдеI = K ∙ Q ∙

where

K = 0.238 - constant;

Q is the flow rate in l / min;

P - fluid pressure in bar.

From the fundamentals of hydraulics (for example Galdin NS Fundamentals of hydraulics and hydraulic drive: Textbook. - Omsk: Publishing house SibADI, 2006. - 145 p., Or Gusev VP Fundamentals of hydraulics. Textbook. - Tomsk. in TPU, 2009.- 172p.) it is well known that the flow rate of liquid Q through the annular section is directly proportional to the diameter of the section and is equal to:

Q = u⋅S, where

u is the fluid velocity in the annular section,

S is the area of the annular section.

Thus, the total theoretical impact force I is directly proportional to the area (respectively, and the diameter) of the annular section.

Since the possibility of increasing the pressure in the entire system of the bottom drain device is limited by the technical parameters of this system, and the holes in the body of the prototype nozzle have a constant diameter, the disadvantage of the prototype is the impossibility of adjusting the flow rate of the liquid through the holes, and, accordingly, the impossibility of changing the impact force of the nozzle.

The technical problem being solved is the lack of the possibility of preliminary adjustment of the impact force of the nozzle.

The technical result of the claimed utility model is to provide the possibility of preliminary adjustment of the impact force of the nozzle depending on the purpose of heating.

The claimed technical result is achieved by the fact that the nozzle of the hydromonitor of the tank bottom discharge device contains a hollow cylindrical body with nozzles directed towards the inside of the tank and with a stop fixed on the upper end of the body, the body has holes for feeding a part of the product into the tank discharge device, and the holes contain threads for attaching additional removable nozzles and removable plugs.

Axes of additional nozzles can be located at an angle to the axis of the body from 0 ° to 90 °. The angles of inclination of the axes of the additional nozzles to the axis of the body are determined by the design of the additional nozzles.

The proposed nozzle for the water monitor of the tank bottom discharge device works in conjunction with the bottom discharge devices equipped with a water monitor. The nozzle of the hydraulic monitor of the tank bottom discharge device connected to the tank drain device is lifted by the hydraulic monitor under the open drain valve under the action of fluid pressure. Such a liquid is an oil product, similar to the one being drained, which actively mixes and heats a viscous product in a tank to a liquid state (publication on the Internet: http://www.koz.ru/catalog/oborudovanie-dlya-zheleznodorozhnogo-transporta/ustroystva-nizhnego- sliva / ustroystva-usn-175g-200g-s-gidromonitorom /).

The presence of threads in the holes in the body allows you to pre-install additional removable nozzles and or removable plugs into the nozzle.

Additional nozzles can be of different diameters, depending on the need to change the impact force of the flow directed through the holes in the body.

When installing the plugs, the fluid pressure increases, and, accordingly, the impact force through the open working nozzles.

Axes of additional nozzles can be located at an angle to the axis of the body from 0 ° to 90 °. Angles from 0 ° to 45 ° ensure that the drain line is cleaned and contaminated, since the impact force vector is directed mainly downward. Angles from 45 ° to 90 ° prevent the adhesion of cold product on the inner surface of the walls of the drain device or provide cleaning of the walls, since the impact force vector is directed mainly towards the wall. The angles of inclination of the axes of the additional nozzles to the axis of the body are determined by the design of the additional nozzles.

Thus, the claimed utility model differs from the prototype in that:

- holes contain threads for attaching additional removable nozzles and removable plugs.

- axes of additional nozzles are located at an angle to the axis of the body in the range from 0 ° to 90 °;

- the angles of inclination of the axes of the additional nozzles to the axis of the body are determined by the design of the additional nozzles.

This ensures that the claimed utility model meets the "novelty" criterion.

The proposed utility model is illustrated by graphic material:

- in Fig. shows a general view of the nozzle of the hydraulic monitor of the tank bottom discharge device.

The jetting nozzle of the bottom discharge device of the tank (Fig. 1) contains a hollow cylindrical body 1 with nozzles 2 directed towards the inside of the tank (the tank is not shown). A stop 3 is fixed on the upper end of the housing 1.

The body 1 has holes 4 for feeding a part of the product into the tank drain device, holes 4 contain threads 5 for attaching additional removable nozzles 6 and removable plugs 7.

The axes of the additional nozzles are located at an angle " a " to the axis of the body from 0 ° to 90 °. Angles from 0 ° to 45 ° ensure that the drain line is cleaned and contaminated, since the impact force vector is directed mainly downward. Angles from 45 ° to 90 ° prevent the adhesion of cold product on the inner surface of the walls of the drain device or provide cleaning of the walls, since the impact force vector is directed mainly towards the wall. The indicated angles " a " are provided by the construction of additional nozzles 6.

The claimed utility model works as follows.

The proposed nozzle of the water monitor of the tank bottom discharge device operates in a set with the bottom discharge device equipped with a water monitor (device not shown). The jetting nozzle of the tank bottom discharge device is attached to the jetting nozzle by means of the thread 8 shown in FIG. 1.

The nozzle of the hydraulic monitor of the lower tank drain device is lifted by the telescopic hose of the hydraulic monitor under the open drain valve of the tank drain device under the action of fluid pressure until the end of the stop 3 is pressed against the drain valve of the tank drain device 10 (the tank and the tank drain valve are not shown).

The presence of a thread 5 in the holes 4 of the body 1 allows you to pre-install additional removable nozzles 6 and or removable plugs 7 into the body 1. Additional nozzles 6 can have different diameters, depending on the need to change the impact force of the flow directed through the holes 4 in the body 1. When installation of plugs 7 increases the pressure of the liquid, and, accordingly, the impact force through the open working nozzles 2 and 6.

The heating product through the cavity of the body 1 enters the nozzles 2 and 6. Depending on the combination of pre-installed additional nozzles 6 and plugs 2, the impact force of the flow through the nozzles 2 and 6 changes, which allows, depending on the task, to prevent clogging of the drain line with pieces of drained viscous product, clean the walls of the drain line or reduce the impact force of the flow through the holes 4 to redistribute the impact force to the nozzles 2 for more efficient heating of the cargo inside the tank.

Thus, in comparison with the prototype, it is possible to pre-adjust the impact force of the nozzle depending on the purpose of heating .
