Abstract

This invention relates to the coking industry and relates to devices for dispensing wet fine particulate material such as colloidal sulfur. The purpose of the invention is to expand the field of application of the feeder, increasing the accuracy of dosing and adjusting the volume of portions of the material being metered. The goal is achieved by the fact that in the known construction of the feeder one of the walls of the rotor is made movable and has adjusting segments on it, and the scraper consists of two overlapping plates, one of which is able to rearrange according to the position of the adjusting segments, while the feeder-dispenser is provided with a forming a roller located at the exit of the cell from the feed hopper, and a safety knife mounted between the forming roller and the adjusting segment. 1 hp f-ly, 4 ill.

Description

This invention relates to coke chemistry, namely, to devices for dispensing wet fine powdered material prone to coking, such as colloidal sulfur.

The aim of the invention is to expand the field of application of the feeder, increasing the accuracy of dosing and adjusting the volume of portions of the dosing material.

FIG. Fig. 1 shows a feeder-dispenser, obi (Id; VIEW; Fig. 2 - section A-A in Fig. 1; Fig. 3 - node I in Fig. 2; Fig. 4 - safety knife assembly.

The feeder-dispenser consists of a storage hopper 1 of material to be blended, equipped with a rotary 11TS1ms agitator 2, at the end of the shaft of which the blade 3 is fixed, working on the propeller principle, loading funnel 4, rotor 5 with cells, one of the walls 6 of which is made mobile. Moving the movable wall 6 is carried out with the help of a screw 7 screwed into the axial hole of the rotor shaft 5, on the inner end of which a rod 8 is fixed, pivotally connected to it so that when the screw rotates, 7 tons ha 8 moves progressively. The rotor shaft 5 has grooves, through which the finger 9 is passed, connecting a yugtl t gu with a movable sleeve 10, on which a movable stack of 6 p is fixed (ttor 5.

either it enters the rotor cell 5, displaces a part of the material from it, or goes out, and the cell volume increases.

The feeder-dispenser also contains the formations of the roller 12, located at the outlet of the cell from the feed hopper 4 and installed in the bearings of the feeder-feeder housing (not shown).

The forming roller is driven by a chain transmission from the axis of the scraper 13, connected through the gear 14 to the rotor 5, and rotates synchronously with it. The scraper 15 provides for the complete removal of material from the rotor cell 5 and consists of two overlapping plates, one of which 16 can be rearranged on the axis 13 in accordance with the position of the adjustment segments 11.

Portions of the material being metered fall into the discharge chamber 17. In order to avoid material getting between the forming roller 12 and the adjusting segment 11 and the mechanism jamming, a safety knife 1B is provided, which is fixed to the body of the feeder and exhibited in accordance with the position of the adjusting segments 11.

Feeder-dispenser works as follows.

The dosing material is loaded into the storage bin 1, in which the rotating agitator 2 separates it from the walls of the bunker 1 and advances into the discharge funnel 4 of the feeder. At the entrance to the feed funnel 4, a pressing blade 3 is installed, fixed to the end of the shaft of the agitator 2 and rotating with it. As a result of this, crushing of lumps of material occurs, which is a wet, soft, abrasive fine powder, prone to clumping. Then the material enters the rotor 5 and, moving with its cell, passes under the molding of the 1M roller 12. In this case, the dose is molded in the volume of the rotor cell 5, and the material is compacted to a constant volumetric weight.

Since the volume of the weight of the material may vary depending on the technological parameters of production, the design of the proposed battel provides for the possibility of

possibility of adjusting the cell volume to adjust the weight of the dose. This is done in the following way. When the screw 7 is rotated into the axial bore of the rotor shaft 5, ton ha 8, attached to the inner end of the screw 7, it makes a translational motion. When this occurs, the finger 9, passed through the grooves of the rotor shaft 5 and connecting the connecting rod 8 with the movable sleeve 10, which presses against the wall 6 of the rotor 5, moves it in motion.

The complete removal of the dose of material from the rotor cell 5 is carried out by a scraper 15 consisting of two overlapping plates, the position of one of which 16 depends on the position of the adjustment segments 11 located on the movable wall 6.

In order to avoid material falling between the forming roller 12 and the adjusting segment 11 and jamming of the mechanism, as well as in accordance with the position of the adjusting segment 11, a safety knife 18 mounted on the housing of the feeder-dispenser is exposed. The resulting operation, the dose of material enters the discharge chamber 17.

The feeder-dispenser is designed to work as part of a chemical reagent packaging line paired with a packaging machine. To ensure synchronism of the feeder and palletizing machine, the rotor 5 is rotated from the palletizing machine drive, and to ensure synchronism of rotation of the scraper 15 and the forming roller 12 with the rotor 5, a reducer 14 is provided in the feeder feeder design.

The use in the proposed invention of the movable wall of the rotor, the adjusting segments placed on it, the pressing blades fixed on the end of the agitator shaft and operating according to the principle of a propeller, a forming roller and a safety knife located between the forming roller and the adjusting segment provide compared to the known feeders the advantages of creating the discharge and dosing of not only compressed caking materials, but also of wet, soft, abrasive fine
