Description

The utility model relates to production lines for manufacturing composite products that can be used for reinforcing conventional and prestressed building structures used for reinforcing binding media: for reinforcing heat-insulating wall structures, for reinforcing the soil of the foundations of buildings and structures, including the foundations of highways and dear.

Known technological lines for the manufacture of composite reinforcement, for example, the line according to the patent of the Russian Federation No. 2287646, Е04С 5/07, 2006, including creel with roving bobbins, leveling device, annealing chamber, impregnating bath with a tension device, squeezing device, molding unit, device spiral winding, polymerization chamber, pulling device, cutting and reeling units. The molding unit is made in the form of a matrix installed in front of the spiral winding zone, the squeezing device is made of elastic elastic material, the leveling device is made in the form of a comb.

The disadvantages of this line are the environmental friendliness of the production of composite reinforcement, the lack of a cooling unit and increased energy consumption.

As the closest analogue to the claimed technical solution, a production line for manufacturing composite reinforcement according to the RF patent No. 2468161, Е04С 5/07, 2011 can be adopted. The line also includes creel with coils, a heating unit, an impregnating and squeezing device, a winding device, a polymerization unit, a cooling bath, a pulling device, a length counter and a cutting device. According to the invention, each bobbin reel has its own tensioning device, lamellar heating elements are installed in the heating block, the impregnating device comprises a drum, a fairing and. adjustable heating element; the drum is installed so that part of it is in the impregnation bath, and part is above the impregnation bath, the winding device contains a controller connected to the drive of the coil, the drive of the faceplate and a photocell associated with the lead, the polymerization unit contains sections with thermal oil heating elements, the pulling device is made of a caterpillar type, the cutting tool of the cutting device is an abrasive wheel.

The disadvantages of the prototype include the environmental friendliness of the production of composite fittings, for example, the need to dump cooling water together with fiberglass into the sewer, the use of a drum that does not provide high-quality impregnation of the entire thickness of the bundle of glass or other fibers and increased energy consumption for supplying heating elements.

The purpose of the utility model is to eliminate the above disadvantages of the prototype and increase the environmental friendliness of production.

The technical result is achieved as follows: in a production line containing creel crest with coils, leveling device, heating block, pulling device, length counter, cut-off and reeling device, a closed composite valve cooling system is applied with automatic maintenance of the cooling water parameters and its filtering, full or partial replacement TENOV infrared emitters, and replacing the drum in the impregnating device with an impregnating bath with a pressure device.

A patent search showed the absence of technological lines for the manufacture of composite reinforcement with the proposed combination of features.

Thus, in this case, the known elements are combined with new bonds, give the production line new properties that are manifested in positive effects, as a result of which the solution can be recognized as having an inventive step.

The essence of the utility model is illustrated in the drawing, where figure 1 shows a diagram of the circulating water supply of the cooling bath.

Here, the cooled composite reinforcement 1 passes through the cooling unit in the form of a tray 2 with control of the level of immersion and overflow, in the middle of which cold water flows, drained through its ends to the collection tank 3. Heated water flows by gravity into the tank 4, where it is cooled by a coil 5 of an industrial air conditioner 6.

The water level in the tank 4 is also automatically maintained by the action of the float valve 7 on the valve 8 supply water from the network.

Chilled water is filtered in a self-cleaning filter 9 and pump 10 returns to the middle of tray 2, etc.

To reach the calculated mode of operation and control the temperature of the cooling water, in addition to the thermostatic expansion valve TRV, a bypass 11 is provided, which returns the cooled water to the tank 4.

The next distinguishing feature from the prototype is the use in the heating unit and the polymerization chamber of the technological line of infrared heaters that can operate by consuming electricity, liquid or gaseous fuel.

The most convenient is the use of electric long-wave low-temperature heating devices that transfer heat directly through infrared radiation. Radiant energy is absorbed by the opposing surfaces, turning into thermal energy, heats them, and they, in turn, give off heat to the air.

This gives a significant (up to 50%) economic effect compared to convection heating of the prototype, where heat is used to heat unused space.

The main structural element of an infrared heater is an emitter emitting infrared radiation due to heating. The electric heater uses: an electric heater in the form of a spiral protected by a quartz tube; ceramic infrared emitter having an extended service life; carbon heater.

Despite their relatively small size, they all have high heat output at a relatively small temperature of less than 600 degrees C, which ensures fire and environmental safety for the process line, as long-wave low-temperature radiant heat is harmless, as well as long (over 25 years) service life.

For directional target heating and protection of the housing from overheating, reflectors made of reflective and heat-resistant material are used, which reduce irrational secondary heating of ambient air.

In the polymerization unit (chamber), infrared emitters are connected in sections that provide high line productivity due to the distribution of the specific heating power along the length of the passing fittings in accordance with the adopted technology

Thus, the use of a closed cooling system for valves, infrared emitters and the absence of a drum in the impregnating device reduces the energy consumption of the proposed production line, its dimensions, increases fire and environmental safety of production and the quality of products.
