SU139865A1 - Instrument for determining the content of excise resins in petroleum and petroleum products - Google Patents

Description

The known instruments for the determination of excise resins according to GOST are exclusively laboratory, not intended for operation in the stream.

A device is proposed for determining excise resins in petroleum and petroleum products on stream.

The device consists of a programming mechanism driven by a synchronous motor, three tanks for reflux, an I-solution and two solenoid valves in each tank, a mixing tank with a fan, a measuring cylinder with a tilting device, photoresistance with a tracking system, an amplifier and secondary recorded device.

A feature of the proposed device is the presence of elements of automatic devices: programming, locking devices, tracking systems. The application of the follower system units measuring the level of polymerization resins deposited on the bottom of a quartz measuring vessel is original. The measurement of the level of polymerization resins, which characterizes the percentage content of excise resins with a fully automated supply of samples, their displacement and transfer of readings to the secondary device is used for the first time.

The drawing shows a schematic diagram of the device.

A device for determining the content of excise resins consists of; an electric motor / type of SD, rotating through a reducer 2, a program mechanism consisting of a shaft with cams 3, which alternately, depending on a given program, turn microswitches 4 on and off. For metering the components there are three tanks 5 supplied with input and output solenoidal valves, Ai, 3,, KS and KG. These tanks through the inlet valves are connected with PG / Gok of the installation, and through the output of the products 6 - with offset-. by teleme 7. The displacement of components in the spacer is carried out by pro jto. 139865 with a 2peller agitator driven by an SD motor S. The product is drained into the measuring cylinder 9 by a solenoid valve KI.

The following system consists of an illumination lamp 10, a photoresistance of FS-K 11, a Kronschtein / 2 and a guide roller 13. The following system is driven by a sleeve 14, driven by a worm roller 15 from the RD-09 16 motor. The electronic system is controlled by an electronic amplifier AU, similar to the amplifiers of electronic bridges. The slider 17 removes the potential from the reichord 18 and transmits it to the secondary device 19.

After the analysis, the tilting device 20 serves to drain the product. - - The measuring cylinder .9 is cleaned through a pipe 21, into which the vapor-air mixture is fed through solenoid valves

8 and the instrument kaRabout proceeds as follows.

The program mechanism turns on the cam B, opens the valves / ((. L2, and fills the containers 5). Then the program mechanism turns off B, K, Dz, -Kz and turns on Bj, Ks, Kv and the product comes out of the containers 5 6 into the mixer 7, where it is moved by a blender with an electric motor for several minutes. Then the program mechanism switches on the BR and K /, and the product is fed to the measuring cylinder 9, where sludge occurs in the product for 20 minutes. The resin is polymerised and settles to the bottom cylinder, you are semi-naked from quartz glass.

After 20 min. From the rest, the program mechanism includes from, which gives power to the electronic amplifier, the power supply of the system; The light from the light bulb L falls on FS-K, included in one of the shoulders of the bridge, and changes its resistance.

The electric amplifier gives an impulse to the reversible motor RD-09} 6, which rotates the worm shaft / 5 and the sleeve 14 mounted on it with the crown 12. 12. Diil the trace of the system continues until Noka is lit with FS-K.

When the rays from the light bulb L cannot pass through the dark layer of polymerised resins, the system stops moving and the slider / 7 removes the potential of the reichord 18, transferring it to the secondary device 19.

Depending on the iroceng content of the resins in the product, their level in the measuring cylinder is mega. To the slider through the tracking system, the slider on the reichord is transferred to the secondary recording device, which is graduated as a percentage of the resin.

After marking the presence of resins in the secondary device 19, the program mechanism turns on B and the tilting device 20, which with a motor turns the bracket with the measuring cylinder .9 fixed to 180 °, and the product is drained into a sewer funnel. The program mechanism then turns on fig and Java, with the cylinder blown by steam through tube 21, after which it turns on 2 and Kg and the cylinder is blown with air to the full essence. and the graduated cylinder is placed in a normal position. Subsequent cycles are similar. Analysis time 30 min.
