Abstract

The invention relates to the shaft of the flax-felt industry and allows to intensify the drying of shaft products while reducing energy costs. A device for drying articles made of capillary-porous materials contains a conveyor located in the chamber for conveying articles and guides mounted above the conveyor for dividing the chamber into separate cells. For supplying the drying agent to the chamber, there are inlet and exhaust ducts and an ejection unit to control the temperature of the drying agent. The visors are mounted vertically. The cells have individual recirculation systems supplying the drying agent through guides made in the form of a set of inclined plates installed with a gap relative to each other. The conveyor for supplying products has holders for them, mounted for axial rotation by means for rotating them. 3 il.

Description

The invention relates to devices for drying piece goods, e.g., bulk shoes made from capillary-porous materials.

The purpose of the invention is to intensify the drying of bulk products while reducing energy consumption.

FIG. 1 shows the device, a general view; in fig. 2 - device holder for shoes; in fig. 3 - technological scheme of the experimental setup.

A device for drying articles made from capillary-porous materials of a shaft shoe contains a chamber 1 with a loading window 2, heat sources (heaters) 3 with guides — a set of inclined plates 4, installed with a gap to one another and fixed on a vertical wall 5, filtering elements 6, fan 7, zigzag vertical partition 8 for dividing the chamber into separate cells, chain conveyor 9, carrying holders 10 for shoes II, device 12 for rotating holders, drive 13, air inlets 14 and 15, recuperative ploobmennik 16, vent system 17.

The device works as follows.

The shoes II are mounted on the holders 10 located in front of the loading window 2. The holders 10 are moved by means of the chain conveyor 9 through the drying chamber 1 and flow around the drying agent. The chain conveyor is driven by the drive 13. When moving, the holders 10 engage with the rotation devices 12 and rotate about their axis. A zigzag-like vertical partition 8 is extended to one half of chamber 1 by five hours. When the holders are passing 10 in. HHCIIKM, the shoe gets twice and the popee. .iii i, - agent. Double Opportunities. ) G 111; : .U with 4

The cell is organized using a set of inclined plates 4, installed one to another with a gap, and a zigzag vertical partition 8. The air heated by the heaters 3 to 120-130 ° C is pumped into the cells by fans 7. Filter elements 6 installed on the ventilation system 17 in front of the heaters 3, provide clean air to the drying chamber 1. Moisture of the first period of the substance is removed with the spent substantive agent from the second drying period, which flows countercurrently through the drying chamber 1. Moisture of the second period is removed when countercurrent with local recycling of the drying agent. The drying agent goes from the inclined plates 4 along the arc to the air intake 14.

The following is a specific example of the device: The length of the drying chamber, m34 Width, m4 Height, m2.5 Length of the chain conveyor, m 77 Number of shoe holders, pcs. 24 Temperature of drying agent at the first stage of drying, ° C 110-115 Temperature of drying agent at the second stage of drying, ° C 120-130 An experimental installation was developed and installed (Fig. 3), allowing to simulate the drying mode in an industrial installation.

The experimental setup consists of an aerodynamic sleeve 1 with the product under investigation. 2 (an approved shaft boot mounted on block 3), a fan 4, heaters 5 and 6, a contact thermometer 7, a thermostat 8, a psychometer 9, weights 10, a filter 11, a differential pressure gauge 12, flaps 13 and a ventilation line 14. For research, install the product 2 with an initial moisture content of 140%, mounted on the shoe 3, in the aerodynamic sleeve 1. With the help of the fan 4, the product is heated to 90-95 ° through the heater 5 With air.

Air circulates through a closed ventilation line 14 with partial discharge of humidified and partial inflow of fresh air. Fresh air is also preheated by the heater 6 before being fed into the ventilation line 14. The air humidity in the ventilation line is controlled by the opening gap value of the flap 13. The contact thermometer

7 regulates the temperature of the air entering the aerodynamic sleeve, its humidity is measured using a psychometer 9. A filter 11 is installed on the ventilation line to clean the circulating air. Air flow is measured using a differential pressure gauge 12. The current humidity is determined by a gravimetric method using a scale 10 connected to the product. M 2, mounted on block 3. The pad is made of lightweight material (plastic) to reduce the weighing error.

By modeling the dryer on an experimental setup, the possibility of reducing the duration of the process of the substance more than 2.6 times was shown.
