Problems solved by technology

The ball 3 rolls between the upper slide 2 and the lower slide 6 for a long time, and the temperature reaches a high level, which easily deforms the upper slide 2 and the lower slide 6 and causes the ball 3 to be resisted, affecting the normal rotation of the ash tray 1
In addition, when the grate burns coal in the furnace at a high temperature to produce large hard slag lumps and the crushing load increases, the pinion pair of the worm gear reducer fixed on the side of the furnace bottom shell 5 is fixed on the ash tray 1 The large ring gear 4 will generate a large radial driving force, causing the upper slideway 2 to rise and separate from the ball 3, and the center of the gray plate 1 will be displaced and unable to rotate. This requires disassembly and maintenance work, which is not only laborious and laborious, but also It also affects the normal operation of production

Embodiment 1

[0019] Embodiment one: if figure 2 As shown, the large ring gear inner transmission furnace bottom assembly of the present invention includes components such as ash tray 1, ball 3, large ring gear 4, furnace bottom shell 5, slideway and the like. The slideway is composed of a glideway 6 and an upper slideway 2, the upper slideway 2 is fixed on the ash tray 1, the glideway 6 is fixed on the furnace bottom shell 5, and the balls 3 are arranged on the upper slideway 2 corresponding to the glideway 6. Between the grooves, the large ring gear 4 is fixed under the ash tray 1 and is located outside the slideway, and extends into the groove 7 of the furnace bottom shell 5 and is connected with the pinion gear of the worm gear reducer fixed on one side of the furnace bottom shell 5 (not shown) to engage the drive. The outer upper end of the furnace bottom shell 5 is provided with a vertical refractory cement ring plate 50, an ash-proof fixing plate 51 and a horizontally arranged ash-...

Embodiment 2

[0023] Embodiment two: if image 3 As shown, the difference from the first embodiment is that the bottom housing 5 and the central hole 8 of the ash tray 1 are provided with an ash tray limiting device, and the upper and lower parts of the ash tray limiting device are connected with the ash tray 1 and the furnace bottom respectively. The shell 5 is fixedly connected, and the top and bottom of the ash tray stopper are rotatably connected by a vertical shaft 11, and the centerline of the vertical shaft 11 coincides with the centerline of the center hole 8 of the furnace bottom shell 5 and the ash tray 1.

[0024]The ash tray limiting device includes a static bearing box assembly fixedly connected to the furnace bottom shell 5, a connecting piece 12 fixedly connected to the ash tray 1, the upper part of the vertical shaft 11 is inserted in the central hole of the connecting piece 12, and the lower part of the vertical shaft 11 is inserted into the center hole of the connecting pie...

Abstract

The invention discloses an internal transmission furnace bottom assembly with a large gear ring, which comprises a furnace bottom case and an arch tray, wherein a chute is arranged between the furnace bottom case and the ash tray, rolling balls for supporting the ash tray to rotate relatively to the furnace bottom case are arranged in the chute, and the outer side of the chute is provided with the large gear ring fixed on the ash tray. The internal transmission furnace bottom assembly is characterized in that a chute cooling device used for reducing the temperature inside the chute is arranged under the ash tray. The internal transmission furnace bottom assembly disclosed by the invention has the advantages of reasonable design and simple structure, and the reformation can be carried out on the furnace bottom assembly of the existing coal gas generator, so the chute and the rolling balls arranged in the chute can work in a proper temperature range, the operation of dismounting and maintaining the furnace bottom assembly through machine halt is effectively avoided, the normal continuous proceeding of the production operation is ensured, and the production efficiency is sufficientlyimproved.

Description

technical field [0001] The invention relates to a coal gas generator, in particular to a large ring gear inner transmission furnace bottom assembly. Background technique [0002] The coal gasifier used in the coal chemical industry or chemical fertilizer production and supply of coal gas uses the reaction of coal combustion and steam to prepare coal gas. The gasifier is composed of a furnace bottom assembly, a water jacket, a grate, a furnace body, a top cover, It is composed of air outlet, ash box and transmission mechanism. The coal is burned on a grate, which is fixed to the upper end of the ash tray. Such as figure 1 Shown, present furnace bottom assembly is made of components such as ash tray 1, ball 3, ring gear 4, furnace bottom shell 5, slideway. The slideway is composed of a glideway 6 and an upper slideway 2, the upper slideway 2 is fixed on the ash tray 1, the glideway 6 is fixed on the furnace bottom shell 5, and the glideway 6 and the furnace bottom shell 5 a...
