Warehouse bottom block-shaped discharging device
The utility model relates to a discharge apparatus technical field, concretely relates to storehouse bottom block form discharge apparatus.
The bottom discharging device is mainly used for discharging in bulk cement storehouses. The pneumatic discharging device can be pneumatically controlled and manually operated, and is uniform in discharging, simple in structure and convenient to operate.
The prior silo bottom discharging device can not meet the discharging function of materials larger than 50mm, and the materials are easy to block when a valve is closed.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a storehouse end piece form discharge apparatus to prior art's defect with not enough.
In order to achieve the above object, the utility model adopts the following technical scheme: the utility model provides a storehouse bottom block form discharge apparatus, includes the discharge hopper, the upper end of discharge hopper sets up the feed inlet, and its lower extreme sets up the discharge gate, still includes fan-shaped ooff valve, electric hydraulic rod valve and electric hydraulic valve, and its innovation point lies in: the left and right sides all sets up fan-shaped ooff valve on the discharge hopper, the fixed electrohydrodynamic stick valve that sets up double open structure on the feed inlet, the fixed electrohydrodynamic valve who sets up double open structure on the discharge gate.
Furthermore, when the sector door of the sector switch valve is closed, a gap is reserved between the sector doors.
Furthermore, the fan-shaped switch valve, the electro-hydraulic rod valve and the electro-hydraulic valve are all closed inwards at two sides.
Furthermore, still include PLC control system, this system respectively with fan-shaped ooff valve, electro-hydraulic rod valve and electro-hydraulic valve electric connection, and every valve all adopts the time delay to close.
After the structure is adopted, the utility model discloses beneficial effect does:
the utility model has simple structure and convenient use, and can effectively shorten the valve body stroke and reduce the resistance when closing by arranging the electro-hydraulic rod valve with the double-opening structure; by arranging the two fan-shaped switch valves, a gap is reserved in the middle when the switch valves are closed, so that main materials can be clamped, and the push rod cannot be damaged; through the electro-hydraulic valve with the double-opening structure, small or powdery materials can be effectively prevented from falling off when the electro-hydraulic valve is closed. The utility model discloses wholly adopt PLC control, the time delay of closing of every way valve is closed, prevents that cubic material from falling to be blocked by one valve down, and the sealed raise dust point had both been guaranteed in the change of valve, especially middle sector switch valve's application, can effectively close cubic material again and not fall.
Fig. 1 is a schematic structural diagram of the present invention.
Description of reference numerals:
the device comprises a discharge hopper 1, a feed inlet 2, a discharge outlet 3, a sector switch valve 4, an electro-hydraulic rod valve 5 and an electro-hydraulic valve 6.
The present invention will be further described with reference to the accompanying drawings.
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and the following detailed description. It should be understood that the detailed description and specific examples, while indicating the invention, are given by way of illustration only.
Referring to fig. 1, a warehouse bottom block-shaped discharging device comprises a discharging hopper 1, wherein a feeding port 2 is arranged at the upper end of the discharging hopper 1, a discharging port 3 is arranged at the lower end of the discharging hopper, the warehouse bottom block-shaped discharging device further comprises a fan-shaped switch valve 4, an electro-hydraulic rod valve 5 and an electro-hydraulic valve 6, the fan-shaped switch valve 4 is arranged on the left side and the right side of the discharging hopper 1, the electro-hydraulic rod valve 5 of a double-open structure is fixedly arranged on the feeding port 2, and the electro-hydraulic valve 6 of the double-open structure is.
The electro-hydraulic rod valve 5 and the electro-hydraulic valve 6 with the double-opening structure in the embodiment are both the electro-hydraulic rod valve 5 and the electro-hydraulic valve 6 which are arranged by opening two doors.
In this embodiment, when the sector door of the sector switch valve 4 is closed, a gap is left between the sector doors, and a gap is left in the middle of the closing, so that the main material can be clamped, and the push rod cannot be damaged.
In this embodiment, the fan-shaped switch valve 4, the electro-hydraulic rod valve 5 and the electro-hydraulic valve 6 are all closed inward at two sides.
In this embodiment, still include PLC control system, this system respectively with fan-shaped ooff valve 4, electro-hydraulic rod valve 5 and 6 electric connection of electro-hydraulic valve, and every valve all adopts the time delay to close, can prevent that cubic material from falling down and blocked by next valve, the change of valve, especially middle fan-shaped ooff valve's application has both guaranteed sealed raise dust point, can effectively close again that cubic material does not fall down.
The above description is only for the purpose of illustrating the technical solutions of the present invention and not for the purpose of limiting the same, and other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present invention should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
