SU1712281A1 - Device for warming up viscous products in tank - Google Patents

Abstract

The invention relates to loading and unloading operations, in particular, to devices for heating viscous products in a tank. The purpose of the invention is to increase the efficiency of heating. The device for heating the viscous products in the tank is equipped with erosion devices, on the branch pipes of which wheels are installed in the lower part. The shell of each erosion device is equipped with guide vanes. On the pipes of both erosion devices in the bottom. Its parts are mounted wheels. When warming up, they lower the erosion devices inside the tanks! with the help of a lifting-transport rack through which a certain steam flow is supplied. On the nozzles of the erosion devices, the shells with Laval nozzles rotate. The nozzles are dispersed along the tank, the steam streams coming out of the nozzles are inserted into the thickness of the viscous product and use the guide vanes to move the product, ensuring high efficiency of its heating. 5 or.m. Su to00 The invention relates to loading and unloading operations, in particular to devices for heating viscous products in: a tank. The purpose of the invention is to increase the efficiency of heating. • FIG. 1 shows schematically a part of the device located above the neck of the tank; in FIG. 2 is a part of the device located in the tank in the retracted position, allowing it to be inserted into the neck of the tank: in FIG. 3 - the same. in the working position: in FIG. 4 - the body (shell) of the heater in expanded form, general view: in FIG. 5 - Laval nozzle. A device for heating viscous products consists of a cylinder 1 in which a piston 2 is located with the possibility of moving in a vertical plane. Piston 2 is rigidly mounted on the top 3 and bottom 4 hollow bars. wherein the lower stem 4 is a lifting and lowering rack having a horizontal axis 5 at the lower end (Fig. 2). on which is installed

Description

shirnirno with rotation

The movement of the piston 2 with the rods, i.e. the lifting and lowering rack 4. is provided by supplying oil to the cavities 6 and 7 through pipelines 8 and 9, respectively.

Hollow hollow rods 3 and 4, s also channels to in the piston 2 serve as a steam line.

Lifting stand 4 (aka the steam line 3-10-4) through flexible pipes 11 is connected to the nozzles 12 washout devices. The two nozzles 12 rotatably on the bearings 13 and 14 are fitted with shells 15 with Lawal nozzles 16.

On the pipes 12 of both erosion devices, wheels 18 are installed on the bottom of axles 17, and in the upper part pipes 12 are interconnected by a spring-19 of compression.

Each shell 15 erosion devices are equipped with guide vanes 20.

The device works as follows.

Scouring devices are lowered inside the tank, while the oil is supplied to the over-piston space (cavity 6) via pipeline 8 (Fig. 1).

The washing devices are lowered all the way until the wheels 18 stop in the lower part of the tank, after which under the action of the continuing vertical movement of the lifting and lowering column 4 and the branch pipes 12, the latter are consumed, stretching the spring 19.

The wheels 18 then roll over the bottom of the tank.

At the same time, to ensure immersion of the device, a steam is supplied to the viscous product through a lifting and lowering rack 4, first under steam, and then under

under full pressure. The exit of the Laval nozzles 16 in the form of beams of diverging jets, the steam deeply penetrates into the thickness of the viscous product. In addition, under the action of the reactive forces of the steam jets, rotation is established on the bearings 13 and 14 of the shell 15 together with the guide vanes 20.

The vanes 20 contribute to the intensive mixing of the product volumes of different temperatures, creating a constant wave, which evenly diverges from the center of rotation of the shells 15 in different directions.

The invention allows significantly

shorten the warm-up time of the product, i.e., increase productivity and, in general, improve the efficiency of the device. Formula of the Invention A device for heating viscous products in a tank, including a lifting rack, a steam pipe, communicated by a nozzle with a wash device having a shell with nozzles mounted on the nozzle for rotation
