Abstract
A new type hydraulic handspike is provided, which is essentially composed of a hydraulic station, a pipe system, a hydraulic cylinder (1), a framework (2), a connecting bar (3), a handspike (4), a lead rail (5), a limiting components (6), a leak proof structure (7) and a preheater main body (8); wherein, the framework and the hydraulic cylinder are articulately connected to the preheater main body, forming a triangle of force and displacement triangle by making use of a linkage theory; the two terminals of the connecting bar are respectively articulated with the framework and the handspike; the handspike is arranged on the preheater main body through the lead rail. Thanks to adoptions of a suspension structure, a linkage theory and effective sealing and limit regulation, the device has advantages of simple structure, easy installation and maintenance, smooth operation, good sealing effect and slim blockage chance and so on. Furthermore, the device is light with a small lower platform, thereby saving expenditure.
Description
Technical field:
The utility model relates to the design and manufacturing technology field of lime calcination preheater equipment, particularly a kind of novel lime calcination shaft preheater hydraulic push rod device.
Background technology:
Shaft preheater is the main technique equipment of active lime calcined by rotary kiln system.It is to utilize the high-temperature flue gas and the normal temperature material of discharging from rotary kiln to carry out the heat exchange of gas thing, make material before entering rotary kiln, just be preheating to more than 900 ℃, and realize predecomposition more than 25%, improved the production capacity of rotary kiln, and reduced EGT, save energy consumption, and provide convenience for the exhaust-gas treatment at rear portion.Push rod device is the critical piece of preheater, is used for material is imported rotary kiln uniformly.
Push rod device arrangement form commonly used at present is the console mode structure.The console mode structure mainly is made up of critical pieces such as Hydraulic Station, hydraulic cylinder, push rod, guide casees, and its oil cylinder and push rod system separate with the preheater body, and push rod pushes material under the effect of thrust hydraulic cylinder during pusher along the guide case.The push rod range and the thrust of console mode structure are bigger, but complex structure, equipment is heavier, and it is more to expend heat resisting steel, comparatively bothers during replacing; Owing to adopt and to land structure,, make lower platform also than broad so it is big to take up room; There is certain deficiency in hermetically-sealed construction, and the returning charge that push rod is brought into can not well be discharged, and stops up easily.
Summary of the invention:
For overcoming above-mentioned problems of the prior art, the purpose of this utility model provides a kind of novel lime calcination shaft preheater hydraulic push rod device, and it adopts suspended structure, utilizes the linkage principle, by effective seal, improved the performance and the effect of equipment greatly.
For achieving the above object, the utility model adopts following technical scheme:
Described a kind of novel lime calcination shaft preheater hydraulic push rod device, it is mainly by hydraulic cylinder, framework, connecting rod, push rod, guide rail, stopping means, hermetically-sealed construction and preheater body constitute, one end of hydraulic cylinder is by being articulated and connected on the preheater body, the other end of hydraulic cylinder is connected with the lower end of framework by hinged, the upper end of framework is by being articulated and connected on the preheater body, be provided with on the upper end of framework and the corresponding preheater body position limiting component is installed, the lower end of framework is connected with an end of connecting rod by hinged again, the other end of connecting rod and push rod are by being articulated and connected, push rod is installed on the preheater body by the guide rail of bottom, the hinged end of push rod and connecting rod is provided with hermetically-sealed construction, and hermetically-sealed construction is made up of the annular seal space of putting back-end and the drainage conduit of bottom.
Owing to adopt aforesaid technical scheme, the utlity model has following superiority:
Described a kind of novel lime calcination shaft preheater hydraulic push rod device, its framework, hydraulic cylinder adopt articulated form, are connected on the preheater body, thereby have reduced occupation space; Utilize the linkage principle to form power triangle and displacement triangle, it is more steady to move; The push rod guiding has adopted independent guide rail structure, adopts bolting, and is simple in structure, and installation adjustment is changed convenient; The seal form of push rod is more reasonable, and the waste material of taking out of in the push rod return process is discharged by drainage conduit, can not influence the stroke of push rod because of obstruction, and leaks out by the alternative rubber baffle minimizing system in the past of gravity flap valve is set; Can adjust the stroke of push rod within the specific limits by adjusting stopping means, regulate the inventory that enters rotary kiln, adjust production capacity.
Description of drawings:
Fig. 1 is the structural representation of this novel lime calcination shaft preheater hydraulic push rod device;
Among the figure: the 1-hydraulic cylinder; The 2-framework; The 3-connecting rod; The 4-push rod; The 5-guide rail; The 6-limiting component; The 7-hermetically-sealed construction; 8-preheater body.
Specific embodiment:
As shown in fig. 1: this novel lime calcination shaft preheater hydraulic push rod device, it is mainly by hydraulic cylinder (1), framework (2), connecting rod (3), push rod (4), guide rail (5), limiting component (6), hermetically-sealed construction (7) and preheater body (8) constitute, one end of hydraulic cylinder (1) is by being articulated and connected on preheater body (8), the other end of hydraulic cylinder (1) is connected by hinged lower end with framework (2), the upper end of framework (2) is by being articulated and connected on preheater body (8), be provided with on the upper end of framework (2) and the corresponding preheater body position limiting component (6) is installed, the lower end of framework (2) is connected by a hinged end with connecting rod (3) again, the other end of connecting rod (3) and push rod (4) are by being articulated and connected, push rod (4) is installed on the preheater body (8) by the guide rail (5) of bottom, push rod (4) is provided with hermetically-sealed construction (7) with the hinged end of connecting rod (3), and hermetically-sealed construction (7) is made up of the annular seal space of push rod (4) rear end and the drainage conduit of bottom.
During work, this device is under the pulling force effect of hydraulic cylinder (1), framework (2) is that swing thereupon at the center with the pin joint on the preheater body (8), driving the connecting rod (3) hinged with it moves forward, thereby make with the hinged push rod (4) of connecting rod (3) and do rectilinear motion, uniformly material is pushed along guide rail (5).Stopping means (6) is fixed on the preheater body (8), can contact with it behind framework (2) the swing certain angle, by the signal of telecommunication that spreads out of, feeds back to the electric control system controls hydraulic cylinder and comes and goes; Adjust stopping means (6) position, can adjust the stroke of push rod within the specific limits, regulate the inventory that enters rotary kiln, adjust production capacity; The returning charge that push rod (3) back and forth movement is brought into can be derived by drainage conduit, is not easy to stop up.
