RU1834700C - Device for reservoir self-feeding by anhydrous ammonia - Google Patents

Abstract

The device is made in the form of a switching pipeline equipped with two valves, each of the valves is equipped with a fitting for connecting the gas hoses of the filled tank, while one end of the valve is plugged and the other end is connected via a fitting and a portable pipe to the adapter, it is also wound through the upper safety valve hatch in a container of water. In addition, the transition fitting is rigidly attached to the switching pipeline and connected to it by a valve. 1 ml

Description

The invention relates to agriculture, in particular, to plants and devices for refueling field tanks of the SPA-50 type with anhydrous ammonia, which is used as a mineral fertilizer.

The aim of the invention is to simplify the design, increase the productivity of the reliability of the device and operation.

The invention is illustrated in the drawing, which shows a device, a General view.

The inventive device for filling containers with anhydrous ammonia includes a filling tank 1, which is equipped with a liquid valve 2 and a gas valve, an empty tank 4, also equipped with a liquid valve 5 and a gas valve 6. Liquid valves 2 and 5 with liquid sleeves 7 and 8 are connected to a transition fitting 9. which, through a valve 10 and a pipe 11, is connected to a switching pipe 12 on which valves 13 and 14 are installed. These valves are connected to the gas valves 3 and 6 by means of hoses 15 and 16. The inlet pipe 12 is plugged with a flange 17 and a flange with a fitting 18, which is connected by a sleeve 19 to a device for preparing ammonia water 20 installed in a tank with water 21, valve 22 is connected through a pipe 23 to valves 24 and 25. Closed device for filling containers anhydrous ammonia operates as follows. First, the gas valve 3 of the filled eMKOCTMj and the valve 13, the liquid valve 2 and the liquid valve 5 of the empty container are opened. Due to the differential pressure of ammonia between the empty and filled containers, the gas line through the switching pipe 12, a flange with a fitting

18, sleeve 19, a device for preparing ammonia water 20 is connected to water located in a container 1 where there is a static water level pressure. Due to the pressure of ammonia in the tank 4, liquid ammonia is pumped into the tank 1. Pr, and filling the tanks from the SPA-50 opens the gas valve 6, valve 14, while valves 3 and 13 remain closed, and the ammonia is pumped due to vapor pressure into the tank 1 and passes from it to the tank 4. After completion of the self-filling and refueling processes and closing the valves 2, 5 and 3.13 (or 4, 14), the ammonia remaining in the arms 7 and 8 is discharged through the valve 10 into the switching line 12. Bleed (ambassador of check of pressure by a manometer) ammonia from the valve 24 minutes and 25 through pipe 23 and valve 22, is supplied to the switch line 12. The incoming gaseous ammonia in the tank 21 forms ammonia water. A container 21 is also used for storing water. The technical and economic effect of using a device for refueling containers with anhydrous ammonia consists of the following indicators:

there are no bulky ycTanoi wok compressor, two installations are missing;

in the TSSR, it is necessary to have approximately 200 such devices, which means that approximately only on compressor plants can one save significantly;

by simplifying the design of the device, its operation is simplified, which leads to cheaper maintenance of the device;

by increasing the reliability of the claimed device in operation, the safety of the process for producing ammonia water is substantially improved;

by lowering the pressure of the gas line, the operational safety of the device and the entire process for the production of ammonia water is also increased.
