Abstract

The invention relates to a roller feed valve. The roller feed valve comprises an inner barrel and an outer barrel, wherein the inner barrel is arranged in the outer barrel; the upper end and the lower end of the inner part of the inner barrel are fixedly connected with a front inner barrel disk and a rear inner barrel disk respectively; the upper end and the lower end of the inner part of the outer barrel are fixedly connected with a front outer barrel disk and a rear outer barrel disk respectively; one end of a front disk feed valve shaft 7 is fixedly connected with the front inner barrel disk, and the other end of the front disk feed valve shaft is made into a valve action structure; a pressing cover is pressed between the front outer barrel disk and the front disk feed valve shaft 7; one end of a rear disk feed valve shaft is fixedly connected with the rear inner barrel disk, and the other end of the rear disk feed valve shaft is assembled in a groove on the rear outer barrel disk; and two side walls of the inner barrel and the outer barrel are concentrically provided with a material inlet and a material outlet. The roller feed valve provided by the invention is mainly suitable for closed feeding in various occasions, in particular for normal inputting and outputting of various storage bin materials with water content of less than 6%; and the working efficiency is improved, and the labor intensity of operators is greatly reduced at the same time. Meanwhile, the roller feed valve has the advantages of simple structure, good sealing performance, economy and applicability, reliability in operation, easiness in overhauling, getting-stuck prevention and the like.

Description

The cylinder baiting valve

Technical field

The present invention relates to the input and output technical field of storage warehouse material, particularly a kind of cylinder baiting valve the during blanking of metallurgical furnace kiln material storage warehouse.

Background technology

The metallurgical furnace kiln material is varied, and character complicacy and viscosity are bigger, and the aqueous ingredients of various materials also there are differences.During from the blanking of material storage warehouse; The blanking amount of material is not easy control very much: when the blanking amount hour; Solid accumulation can be deposited on the storage warehouse bottom too much and block feed opening in the storage warehouse; With the operating rate that directly has influence on metallurgical furnace kiln, also cause because of handling failure simultaneously and bring bigger working strength to the employee.When the blanking amount was big, the material amount that follow-up equipment receives was uncontrollable.

Summary of the invention

The technical matters that the present invention will solve provides a kind of good seal performance, the adjustable gate aperture, and reliability is high, succinct practical cylinder baiting valve.

The present invention adopts following technical scheme: a kind of cylinder baiting valve, and this cylinder baiting valve comprises inner core and urceolus, this inner core places said urceolus; The inner upper and lower end of said inner core is affixed inner core shroud and inner core hub disk respectively; The inner upper and lower end of said urceolus is affixed urceolus shroud and urceolus hub disk respectively; Shroud blanking valve shaft 7 one ends and said inner core shroud are affixed, and the other end is made as the valve event structure; Gland is pressed between said urceolus shroud and the shroud blanking valve shaft 7, and gland packing is tamped in the centre; Hub disk blanking valve shaft one end and the affixed outer other end of said inner core hub disk are fitted in the groove on the said urceolus hub disk; Have inlet point and discharging opening on the two side of said inner core and urceolus with one heart.

The present invention mainly is applicable to the airtight blanking of various occasions, is specially adapted to the normal input and output of aqueous ingredients less than 6% various storage warehouse materials, has improved operating efficiency; Alleviated simultaneously operating personnel's labour intensity greatly.Simultaneously, have simple in structure, good seal performance, economic and practical, running is reliable, be prone to maintenance, anti-sticking is waited indefinitely advantage.

Description of drawings

Fig. 1 is a structural representation of the present invention.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is done further detailed explanation.

With reference to Fig. 1, a kind of cylinder baiting valve, this cylinder baiting valve comprise inner core 1 and urceolus 2, and this inner core 1 is coaxial to place said urceolus 2; Said inner core 1 inner upper and lower end welds inner core shroud 3 and inner core hub disk 4 respectively; Said urceolus 2 inner upper and lower ends weld urceolus shroud 5 and urceolus hub disk 6 respectively; Shroud blanking valve shaft 7 one ends and 3 welding of said inner core shroud, the other end is made as the valve event structure; Gland 9 is pressed between urceolus shroud 5 and the shroud blanking valve shaft 7, and gland packing is tamped in the centre; Blanking valve shaft 8 one ends and the outer other end of said inner core hub disk 4 welding are fitted in the groove on the said urceolus hub disk 6, guarantee the axial concentricity of inner/outer tube; Have inlet point 10 and discharging opening 11 with one heart on the two side of said inner core 1 and urceolus 2.This inlet point 10 is square with discharging opening 11.And the feed inlet and outlet size on the said inner core 1 all greater than the feed inlet and outlet on the said urceolus 2, has reduced the valve event resistance, charging hole on this urceolus and the sealing of storing storehouse feed opening successive welding, discharge opening on the urceolus and the sealing of material transfer equipment successive welding; Connection of the present invention adopts successive welding can guarantee connection tightness, the space sealing property of equipment, has solved the problem that material is revealed in the blanking process.

Groundwork of the present invention is: external impetus input shroud blanking valve shaft 7 drives rotatablely moving of inner core; The angle that relies on inner core to rotate realizes that the size of the square charging hole space coincidence of inner/outer tube degree is to reach the blanking amount and the blanking speed of control material; Because shroud blanking valve shaft 7 and hub disk blanking valve shaft 8 and inner core concentric; Can guarantee good concentricity during assembling, guarantee that the switch motion of valve is smooth and easy.This cylinder baiting valve can be controlled the blanking amount and the blanking speed of material fully in the process of shroud blanking valve shaft 7 half-twists.
