Description

The utility model relates to the production of briquettes from wet polydisperse materials and can be used, for example, to obtain briquetted fuel from peat, feed briquettes.

A known method and device for producing peat briquettes (SU No. 1645287, 04.05.89, C 10F 7/04). The device comprises a preparatory compartment, a dryer, a dryer dust collector, a stamping briquette press, an adjoining section, a cooling tray section, a receiving hopper with an up mouth, a pipeline, a grinding fan and a cyclone. The peat that has been prepared is sent to the dryer and dried to a predetermined humidity. Peat dryer is separated from the gas carrier in the dust collector and fed to the briquette stamp press. The briquette tape at the exit from the matrix channel is crimped with adjustable force by the rollers. Then the surface scale is peeled off, crushed and pressed together with peat dryer. Compressed briquettes arrive at sequentially installed: / cooling trays.,

A device is known for briquetting milled peat (OS Gofrin et al. Technology of peat processing, Moscow, Nedra, 1986, pp. 133-134). It contains a hopper with a plate feeder, a conveyor belt for transporting peat to the drying compartment with a screen, which distributes the raw materials through the screw feeders into the hopper

dryer furnaces and hopper, grinding fan / providing pneumatic conveying of peat from the dryer to the dust deposition system, from where dried peat is fed to briquette presses and then to cooling trays.

A known method of producing briquettes from polydisperse materials, such as peat, and a briquette plant with a pneumatic separation dryer (I.F. Largin, Peat Handbook, Moscow, Nedra, 1982, pp. 455-459). The method consists of the following operations: preparing peat for drying, drying with a pneumatic separation dryer to a moisture content of 15-20%, pressing dried, cooling and storing briquettes.

The briquette plant consists of a receiving hopper, feeder, belt and bucket conveyors, which feed the raw materials to the distribution conveyor of raw materials and screenings, from where part of the feed is fed to the furnace, and part to a pneumatic separation dryer. From the dryer, raw materials are transported through cyclones to a stamping press, then to cooling chutes and a finished product warehouse.

The devices described above have the following significant disadvantages: low productivity and low quality briquettes.

The tasks to which the proposed utility model is aimed are to increase the productivity of the process for producing briquettes from polydisperse materials and to improve the quality of briquettes.

The tasks are solved as follows.

A briquette plant for producing briquettes from polydisperse materials contains a receiving hopper and a feeder for feeding material into a dryer with a pneumatic separator, which is connected to the furnace on one side and to a dust deposition device, a gateway feeder, a stamping press connected to cooling trays, a smoke exhauster , and differs in that the receiving chamber of the briquette stamp press connected to the gateway feeder has

 /

the cross section of the outlet, at least on one side parallel to the direction of movement of the stamp, is smaller than the cross section in terms of the loading chamber, and a half of the air outlet is placed along the aforementioned side of the loading chamber, which is connected with cooling trays made in the form of stationary guides with a channel between them for moving briquette strips in it, and the guides are provided with rollers mounted on the guides and protruding above them towards the longitudinal axis of the guides.

The proposed utility model meets the criterion of novelty, since from publicly available sources of information, there are no known technical solutions characterized by the above-described set of essential features.

The proposed utility model is illustrated in the figure. Figure 1 shows the technological scheme of the briquette plant

The briquette plant consists of a receiving hopper 1 with a screw feeder 2 located in it, supplying the wet material to the dryer 3 with a pneumatic separator 4. Flue gases generated in the furnace 5 during fuel combustion enter the same. The output of the pneumatic separator 4 is connected to the dust deposition system b, from which the material through the airlock feeder 7 enters the briquette stamp press 8, and the flue gases are transported behind the dust deposition system b, the smoke exhaust 9. The device is equipped with a grinding fan 10, the input (suction) pipe of which is in communication with the nozzle for entering the wet particles of the pneumatic separator 4, and the outlet nozzle of the grinding fan 10 is connected to the middle section of the dryer 3 by a gas duct P1 that has a tangential entrance to the dryer and the system pneumatic my 11 for supplying the dried material into the furnace 5, in which the material is fed by screw feeder 12 installed under schlyuzovym feeder 7 pyleosazhdeniya system used. The suction section of the pneumatic conveying system 11 is connected to the exhaust pump from

stamp press 8, which is connected to the cooling trays 13.

The plant operates as follows.

Wet material enters the receiving hopper I, from which it is fed with a screw feeder 2 to the bed dryer 3 with a pneumatic separator 4. Flue gases for drying and transporting the material are generated in the furnace 5 when the dried material is burned in it. From the pneumatic separator, the dried material enters the dust deposition system b, from which the material through the airlock feeder 7 enters the briquette stamping press 8 to form briquettes, and the flue gases are transported behind the dust deposition system b, the smoke exhauster 9. The wettest particles of the material that are in common the flow of material in the drying tract, is allocated in a pneumatic separator 4 and through the nozzle output of wet particles enter the grinding fan 10, where they are crushed and again fed to the dryer in 3 leading part of the dryer, where the flue gases are still sufficiently high temperature. A part of the dried material that has passed through the lock feeder 7 is fed through a screw feeder 12 to the pneumatic conveying system 11, which feeds it for combustion into the furnace 5 to generate flue gases.

The suction section of the pneumatic conveying system 11 is connected to the vacuum cleaner from the stamping press 8 from which the finished briquettes are delivered to the cooler; these trays 13 and further to the finished goods warehouse. Structurally, the press 8 is designed so that the cross section of the outlet of the receiving chamber, into which briquetting material is supplied from the lock feeder 7, is parallel to the direction of movement of the stamp on the one hand and has a smaller section in terms of the loading chamber, and the air exhaust cavity is placed along the said side of the loading chamber . This improves the filling of the pressing chamber with briquetted material. Ready briquettes from the press 8 are fed to the cooling trays 13, which contain

stationary guides / placed with the formation of a channel for moving briquette strips in it. The guides are equipped with rollers, due to the introduction of which increased the cooling time of the briquettes in a compressed state, which accordingly leads to an increase in the quality of the briquettes.

The proposed technical solution can find application in the creation of plants for the production of fuel briquettes from peat and brown coal.
