Abstract

The invention relates to tank cars for the bulk transportation of pulverulent materials, for example dry cement and other heavy powdered cargo, having a pneumatic unloading system. The present tank comprises a tank body fastened on a frame, said tank body having a discharging device. Pneumatic tubes and a system of ramps and splitters are disposed inside of the tank body. An air supply line consists of a control console disposed in a box, air ducts, coupling valves, and safety valves. The tank is equipped with auxiliary air ducts that are connected to the main air ducts and are capable of being independently opened/closed by means of additional coupling valves. Each pneumatic tube is removable and is equipped with an additional air intake in the end part of the pneumatic tube for the intake of air from an auxiliary air duct. The invention makes it possible to completely unload a tank and makes conducting repairs convenient.

Description

Tank

The invention relates to tank cars for the transportation of pulverulent materials and can be used for transportation, for example, of dry cement and other heavy powdery cargoes in bulk with a pneumatic discharge system from manufacturing enterprises to consumer enterprises.

Known tank car for transportation of dusty materials, including a tank, inside the boiler which is mounted: second bottom, four inclined separate trays equipped with a porous bottom, aero boxes, dividers and slopes. When compressed air enters the trays, the pulverized material moves to the discharge pipe located in the middle of the boiler and equipped with a throttle valve. Through the nozzle, the material is transported by air further through the pipeline to the storage rooms (see copyright certificate SU N ° 143420, publ. In the "Bulletin of inventions" N ° 24 for 1961).

The disadvantage of this solution is the difficulty of repairing aero boxes, which must be performed directly in the boiler; Another disadvantage is the proximity of the air supply nozzles in the aerial boxes to the unloading unit, due to which a significant cargo remain remains in the end parts of the boiler during unloading.

The closest technical solution is a tank for transporting cement, which includes a cylindrical boiler mounted on the frame using special clamps, air communication with a control panel located in the box, and unloading device. Inside the boiler there are four aerial trays, which serve for aeration (loosening) of compressed cement air. The volume of the boiler is divided by two dividers and four side slopes into two parts: the upper one is the cargo one and the lower one is the slope. Side slopes running along the entire boiler direct the cement in the cargo part to the longitudinal axis of the boiler, and the dividers located at the bottoms ensure that the cement slides along the aerial trays to the discharge pipe. Aerial trays are detachable gutters made of porous material in the form of conveyor belts through which air passes for aeration of cement. To prevent sagging of the tape under the weight of cement, a grate is installed underneath it in the gutter. Aerial trays have a bias towards the center of the boiler, form a funnel near the discharge nozzle, which provides faster unloading of cement. To ensure the supply of compressed air required during pneumatic unloading, air communication is used, which consists of a manifold located in the reinforcement box and air ducts. The collector is a control and distribution panel for controlling the air supply during unloading of cargo. It includes: a pressure gauge connected by a tube to the boiler pivot space, a safety valve, which, when air is supplied from the compressor station to the manifold, maintains pressure in the boiler and air communication, a coupling valve for the air inlet to the manifold from the compressor unit of the discharge point; two cranes for air inlet under aerial trays from one and the other end of the tank and a valve for supplying air to the discharge hose, a valve for starting air under aerial trays (see. "Cars for cement transportation." Slezin VI, Chinov MI Izd -vo. ^ Transport ”, 1972, p. 4, 7, 1 1-13).

The disadvantage is the proximity of the air supply nozzles to the airlock to the unloading unit, due to which a significant cargo remain remains in the end parts of the boiler during unloading. The technical result of the present invention lies in the fact that the proposed design of aerial trays with an air communication system makes it possible to achieve full discharge of the tank due to the additional supply air duct to the aerial trays. Also, due to removable aerial trays, convenience is achieved during repairs.

The technical result is achieved by the fact that the tank includes a boiler mounted on the frame, air communication and an unloading device, with aerial channels and a system of slopes and dividers placed inside the boiler, and air communication consists of a control panel located in the box, air ducts, clutch taps and safety valves , characterized in that the tank is additionally equipped with auxiliary air ducts connected to the main and having the ability to independently enable / disable means additional coupling th taps, each in turn aerolotok removable and is equipped with an additional air inlet in the end portion aerolotka from the auxiliary air duct.

The claimed technical solution is illustrated by drawings, where in FIG. 1 shows a general view of the tank; in FIG. 2 - sectional boiler; in FIG. 3 - aerial view side view; in FIG. 4 - aerial tray top view; figure 5 is a General view of the system of aerial trays with air communication and unloading unit.

The tank contains a boiler 1, mounted on the frame 2, and air communication 3, mounted on the boiler 1. In turn, air communication 3 consists of a reinforcement box 4, a system of main 5 and auxiliary 6 air ducts, coupling taps and safety valves (in Fig. Not shown). Auxiliary air ducts 6, connected to the main 5 and have the ability to independently enable / disable through additional coupling cranes (not shown in FIG.). The unloading device 7 is located below in the central part of the boiler 1. The unloading device 7 is used for pneumatic unloading of the product from the car and consists of an unloading pipe, a nozzle for cleaning, a shutter (not shown in Fig.). Inside the boiler 1 there are air channels 8 and a system of slopes and dividers 9. In turn, each air channel 8 is equipped with a main 10 and additional 1 1 air supply to the end part of the air channel 8. Each air channel 8 lies on the supporting surface and is fixed through the pipe of the main air supply 10 and the eye 12, which allows, if necessary, to remove it and make repairs.

The tank works as follows.

Loading and unloading of tanks are carried out on specialized racks of enterprises of fillers and recipients of cargo.

Air ducts 8 and unloading device 7 are supplied with air from the air network of the car unloading point through air communication 3. Air communication 3 consists in supplying compressed air through the main 5 and auxiliary 6 air ducts to the air ducts 8 through air inlets 10 and 1 1, respectively. Operating modes:

- air supply only to the pipe of the main air supply 10 to the right or left pair of airlocks 8;

- air supply to the nozzles of the main 10 and auxiliary 1 1 air supply to the right or left pair of airlocks 8;

- air supply only to the pipe of the main air supply 10 to all airlocks 8;

- air supply to the nozzles of the main 10 and auxiliary 1 1 air supply of all airlocks 8; - also simultaneously with any of the above modes or without air supply to the aerial trays 8 can be turned on the air supply to the unloading device 7.

After the termination of the operating modes, inside the boiler 1, the presence of cement residue is allowed - for a new car no more than 0.5% of its carrying capacity or 300 kg. For complete unloading of the remaining cargo, it is necessary to sweep the cement to the center of the boiler and repeat unloading.

At the end of unloading, thoroughly clean the boiler and unloading device from cargo residues and then close the unloading device 7.

To ensure the effective operation of the pneumatic unloading system, it is necessary to regularly clean the filter cloth of the airlocks, as well as the surfaces of slopes and dividers.
