Description

 The invention relates to railway transport and the coke industry, and relates to railway technological cars with a sloping floor, in particular coke oven cars designed to transport coke to a coke oven tower and to an unloading ramp.

 Known coke quenching car having an inclined floor covered with lining plates, under which there are gutters for the drain of process water and small fractions of coke. Each trough is equipped with transverse elements mounted obliquely in the direction of the flow of process water. The length of the transverse elements is less than the width of the trough, and adjacent elements are fixed on its opposite sides [1].

 The disadvantages of this analogue are that during transportation of the car from the coke oven battery to the extinguishing tower, due to jolts during movement, small fractions of coke and dust are poured along the inclined plane of the floor along the plate elements, which are inclined, lingering in the gutters only partially, when pushed out along the railway track, polluting the environment, worsening the environment and increasing losses of coke.

 In addition, small particles fall into the gap between the inclined floor and the shutter flaps along the entire length of the car due to irregularities (warping) of the lining plates forming a gap between the shutter and the lining floor plates.

 Known coke quenching car having a body with an inclined floor covered with lining plates, under which there are gutters for the drain of process water and fine coke, in which the gap between the lining floor plates and the shutter is sealed with rubber tape [2].

 The disadvantage of this analog design is that the rubber-fabric seal quickly fails due to high temperature, forming a gap between the plates and the gate through which small fractions of coke precipitate during transportation to the extinguishing tower, increasing coke losses and worsening the environment.

 For the prototype, a coke-extinguishing car was selected that contains an inclined floor, front and end trusses and closures having lower longitudinal strands that are obliquely oriented to the floor plane and form a wedge-shaped gap with the floor, and longitudinal sealing elements are fixed between the floor and the shutters on the strappings, overlapping crevice gap on the sloping floor side. Longitudinal sealing elements are made with open ends to the outer side of the car, are installed on the shutter harnesses with a technological gap and have transverse openings-grooves on the shelf mating with the shutter for fastening to the strands with the possibility of lateral movement. These elements are installed in order to reduce the loss of small fractions of coke [3].

 The disadvantage of this design is that the longitudinal sealing elements are not tight against the surface of the lining plates of the inclined floor, and the adjustment of the gaps with longitudinal grooves (due to warping of the plates, longitudinal strapping and sealing elements) does not provide a gap-free fit of the longitudinal elements to the lining plates of the inclined floor, as a result of which small fractions of coke wake up in the forming slots, polluting the environment and increasing the loss of coke during loading and transportation.

 The invention solves the problem of increasing the efficiency of operation of a coke-quenching car by reducing the loss of small fractions of coke during loading and transportation, reducing environmental pollution, as well as reducing the cost of manufacturing a car.

 To solve this problem, a coke-quenching car containing a body mounted on a frame with gates and an inclined floor covered with lining plates, under which there are gutters for the flow of process water and small coke fractions, has transverse elements made in the form of platforms installed horizontally in the gutters with the formation steps with an inclined floor. The shutter is equipped with movable sections, consisting of corners with leashes attached to the shutter on hinges, and the leashes and corners are fastened with adjusting threaded joints, providing adjustment of the tight fit of the corners to the lining plates of the inclined floor. The number of movable corner sections is 0.5N, where N is the number of lining plates along the gates of the car, and the corners are fitted to the plates in place when installing the car.

 Such a design of a coke-quenching car, in which the transverse elements are made in the form of platforms installed horizontally in the gutters with the formation of steps with an inclined floor, allows the coke fine fractions to be retained on the steps even during movement and shocks, resulting in a decrease in coke losses during loading and transportation and a decrease in environmental pollution . The reduction of coke losses also gives a snug fit to the shutter's adjustment angles to the floor lining plates.

 In addition, the proposed design reduces the cost of manufacturing a car by reducing the cost of an inclined floor, since it allows to reduce the thickness of an inclined stainless steel sheet, since transverse stepped platforms increase the rigidity of an inclined floor, forming a rigid closed frame with it.

 The invention is illustrated by drawings, where in FIG. 1 shows a general view of a coke oven car; in FIG. 2 is a section along AA of FIG. 1; in FIG. 3 - flooring of the car floor (top view with partially removed plates); in FIG. 4 is a section BB of FIG. 3; in FIG. 5 is a view B of FIG. 2; in FIG. 6 is a view D of FIG. 5.

 A coke-extinguishing car consists of a frame 1 (see Figs. 1, 2, 3) mounted on running trolleys 2, and a coke-extinguishing body 3 having gates 4 and an inclined floor 5. Floor 5 is lined with plates 6 installed with a clearance S = 5- 10 mm (see Fig. 3), laid on the transverse beams 7, forming grooves 8 for draining the process water, having platforms 9. Slots S between the lining plates of the shutter 4 and the lining plates 6 of the sloping floor (see Figs. 5, 6) are sealed corners sections 10, fixed through leashes 11 on the hinges to the shutter 4, and are regulated by a threaded connection n and the lead 11. Each corner section 10 during installation is fitted to two plates 6 without a gap by adjusting the threaded connection of the lead 11. The number of movable corner sections is 0.5N, where N is the number of lining plates along the gates of the car.

 The present invention works as follows. When the car is loaded with red-hot coke and transported from the coke oven battery to the extinguishing tower, small fractions of coke wake up through the gaps S between the plates 6 (see Figs. 3, 4) on floor 5, are delayed on the transverse platforms 9 of the grooves 8, as on the “steps” . Shocks during movement do not affect the small fractions of coke lying on horizontal platforms 9, thereby reducing the loss of coke during transportation.

 When quenching coke with water in an extinguishing tower, small fractions of coke are easily washed off from sites 9 and through the gutters 8 of the process water runoff enter the sump for further redistribution.

 The fine fractions of coke detained by the corner sections 10 are poured onto the ramp along with the coke when the shutter 4 is opened to unload the wagon.

 The present invention allows to reduce the loss of small fractions of coke during loading, transportation and unloading of coke from the car, as well as to reduce its cost.
