Description

The utility model relates to pneumatic chamber pumping devices for pneumatic transportation of bulk fine-grained materials, such as cement, alumina, fly ash, petroleum coke, fertilizers, grain, cinder, etc. and are intended for the implementation of pneumatic transportation of material in a "dense flow" over long distances in the pneumatic transport system.

A continuous chamber pump is known for pneumatic transportation of bulk material (RU No. 2026249, IPC B65G 53/40, publ. 09.01.1995.), Containing two chambers, each of which is equipped with a loading hatch with a loading valve, an air release valve, an aeration device, an unloading pipe and an unloading lock, an air supply pipe communicated at one end with a compressor, and the other through discharge air ducts with taps — with aerating devices for chambers to supply air to them when they are being loaded, and the system a automatic control of cameras to ensure their alternate loading and unloading in one transport pipeline. It is equipped with a vortex or jet type vacuum pump mounted on the air supply pipe with the possibility of using the energy of the air supplied through the air supply pipe to create a vacuum in its suction zone, and suction pipelines with shut-off valves, each of which is connected at one end to the aeration device of its corresponding chamber, and another, with the suction zone of the vacuum pump for suctioning air from the chamber when loading it.

Common essential features with the claimed utility model are:

- cameras

- a loading hatch with a loading valve, an air release valve, an aeration device, an unloading pipe and an unloading lock.

The reasons that impede the achievement of a technical result, which is provided by the claimed utility model, are large dimensions (two chamber pumps), design complexity, inaccessibility to quickly wearing parts during their repair, inaccessibility of transporting material over long distances.

Known pneumatic chamber pump for transporting powdered and fine-grained materials (RU No. 2248928, IPC B65G 53/40, published March 27, 2005), comprising a chamber with a loading valve for supplying material to be transported and a valve for releasing compressed air and an aeration device located in the chamber, a pipeline pneumatically connected to the aeration device with an inlet valve for supplying compressed air, a pipe equipped with a throttle to discharge aerated material from the chamber, made with the valve open from the loading side the end of the expansion pipe has a nozzle equipped with a turbulent air jet located in front of the pipe entrance for transporting aerated material.

Common essential features with the claimed utility model are:

- chambers with a loading valve for supplying the material to be transported and a valve for releasing compressed air

- placed in the chamber aeration device,

- pneumatically connected to the aeration device pipeline with an inlet valve for supplying compressed air,

- pipes for issuing aerated material from the chamber.

The reason that impedes the obtaining of a technical result, which is ensured by the claimed utility model, is the structural complexity of the pump, which significantly worsens its performance and can only be applied in the immediate vicinity of the pump with a warehouse for storing bulk material.

The closest in technical essence is a chamber pump for pneumatic transportation of powdered and fine-grained materials (utility model No. 89510, IPC В65G 53/40, publ. 10.12.2009), containing a chamber with a loading valve for supplying the transported material and a valve for releasing compressed air, aeration device with a central aeration cone and aeration cones installed in the bottom of the chamber and a fence located in the central aeration cone connected to the pipe for upper and lower discharge Container material.

Common essential features with the claimed utility model are:

- chambers with a loading valve for conveying the transported material and a valve for releasing compressed air,

- an aeration device with a central aeration cone and aeration cones mounted in the bottom of the chamber,

- a fence located in the central aeration cone, connected to the pipe for upper and lower discharge of material.

The reason that hinder the receipt of a technical result, which is provided by the claimed utility model is the impossibility

The reason that impedes the obtaining of a technical result, which is provided by the claimed utility model, is the inability to transport loose and fine-grained material in a dense stream over long distances.

The objective of the utility model is to create such an intermediate pneumatic chamber pump design that would make it possible to transport bulk material in a "dense stream" through a transport pipeline over long distances to a storage warehouse for a particular production material.

The technical result is to increase productivity by increasing the speed of transportation of the material.

The technical result is achieved by the fact that the intermediate pneumatic chamber pump for pneumatic transportation of bulk and fine-grained materials, containing a pump chamber with a conical aero bottom, a valve for discharging compressed air, a valve for supplying replacement air, a control sensor, an electro-contact pressure gauge, an unloading pipe with aero elements and the discharge gate further comprises a flow separator located above the pump chamber, connected to it by a loading valve, and made in the form of a conical tank with pipe to discharge clean air, and the inner part of the flow separator is made in the form of a downward spiral with self-lining elements, while a section of the transport pipeline is built into its upper part tangentially to the tank wall.

The presence of a separator allows you to separate the air from the bulk material and transport it further. A conventional pneumatic chamber pump during transportation over long distances requires unloading the material, for example, into a silo, and then only the continuation of its transportation.

The proposed solution is illustrated by drawings.

The present utility model is a pneumatic chamber pump (PCN) - Fig. 1 - (I) with an additional device built into it, in its upper part: a flow separator (II), which is made in the form of a conical shape tank, with a built-in tangent to it the upper wall of the section (1) of the transport pipeline (14) through which the material-air mixture enters (FIG. 2 is a top view), a pipe for discharging clean air (2), a downward spiral (3) located inside the reservoir with the elements for self-lamination (4) - (figure 3), boot cl a pan (5), a chamber of a pneumatic chamber pump (PKN) (6), a valve for discharging compressed air (7), an unloading pipe (8), aero elements located in the lower part of the conical bottom of the pump and in the unloading pipe in the aeration zone (9) , a sensor for the loading level of the material ДУ (10), an electro-contact pressure gauge (11), a valve for supplying replacement air (12), an unloading lock (13), to which a transport pipeline (14) is connected for further transportation of the material-air mixture in dense flow "

An intermediate pneumatic chamber pump is built into the transport pipeline at a distance of no more than 250 m from the start of transportation and works as follows: material-air mixture (MVS) moving in a dense stream through the transport pipeline (14), through a distance of not more than 250 m, gets in the GiSP reservoir (I) through the section of the transport pipeline (1), which is built in a tangent to its upper wall (Fig. 2), then, moving along the downward spiral (3), passing through the elements for self-lining (4), - Fig. 3 located opposite the direction q as the flow of the material-air mixture decreases, the flow rate gradually decreases (i.e., the flow rate is extinguished, with simultaneous separation, i.e., separation of the air that goes through the pipe to discharge clean air (2) into the atmosphere from the material entering the lower part of the cone of the GiSP tank, through the loading valve (5) in its open position into the pump chamber (6). Then, a certain amount of material entering the pump chamber arriving to a predetermined level using the control sensor (10) is closed a valve (5), after which the compressed air supply to the lower part of the pump chamber is switched on to the aeration zone (9) through the air elements located in the conical aerodrome and through the air elements located in the discharge pipe (8), and material air air is formed in the pump chamber mixture, in the form of a single integrated medium (UIS) with the properties of movement in a "dense flow", at this moment substitute air is supplied through the valve (12) and the discharge gate (13) opens and the movement of the material-air mixture in the form (UIS) continues through the transport pipeline (14).
