Abstract
The utility model provides a gear pump conveying explosion-proof device, which comprises an upper cover plate, a lower cover plate and a pressure reducing throttle valve; the lower cover plate comprises a bracket, the upper cover plate is provided with an air vent, and the pressure reducing throttle valve is communicated with the air vent through a vent pipe; set up the airtight cooperation of cover plate and lower cover plate, prevent that the air in the cavity that cover plate and lower cover plate formed from directly circulates with the external world, rethread decompression choke valve input air makes the state that is in the pressure-fired in the cavity, prevents that outside air from getting into to lead to inside material to take place burning or explosion reaction.
Description
Technical Field
The utility model belongs to the explosion-proof equipment field, concretely relates to gear pump conveying explosion-proof equipment.
Background
When the gear pump is transported by using a belt, the belt transport mechanism may possibly generate electric sparks or high temperature, and the high temperature or the direct contact of the sparks with combustible gas easily causes fire or explosion, so that the belt transport mechanism needs to be protected from fire and explosion during transport, and meanwhile, the direct contact of the combustible gas with the belt transport mechanism is avoided as much as possible, so that accidents are prevented.
SUMMERY OF THE UTILITY MODEL
Therefore, in order to solve the above problems, an object of the present invention is to provide a gear pump transfer explosion-proof device, which comprises an upper cover plate, a lower cover plate and a pressure-reducing throttle valve;
the upper cover plate comprises a first notch and a second notch, the lower cover plate comprises a third notch and a fourth notch, and the upper cover plate is matched with the lower cover plate;
when the upper cover plate is matched with the lower cover plate, the first notch and the third notch form a feed inlet, and the second notch and the fourth notch form a discharge outlet;
the lower cover plate comprises a support, the upper cover plate is provided with an air vent, and the decompression throttle valve is communicated with the air vent through a vent pipe.
Further, the feed inlet with the discharge gate is equipped with flexible sealing washer. The flexible sealing ring has certain toughness and good heat dissipation performance.
Further, the lower cover plate further comprises a buckle, and the upper cover plate further comprises a stop block matched with the buckle.
Further, the decompression throttle valve is provided with an air pressure sensor and an audible and visual alarm, and the air pressure sensor is electrically connected with the audible and visual alarm.
The utility model has the advantages that:
set up the airtight cooperation of cover plate and lower cover plate, prevent that the air in the cavity that cover plate and lower cover plate formed from directly circulates with the external world, rethread decompression choke valve input air makes the state that is in the pressure-fired in the cavity, prevents that outside air from getting into to lead to inside material to take place burning or explosion reaction.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic structural view of the back side of the present invention;
wherein, 1, an upper cover plate; 11. a vent; 12. a stopper; 2. a lower cover plate; 21. a support; 22. buckling; 3. a pressure reducing throttle valve; 31. an air pressure sensor; 32. an audible and visual alarm; 4. a flexible sealing ring; 5. a feed inlet; 6. and (4) a discharge port.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings.
Example 1:
fig. 1-2 show a gear pump conveying explosion-proof device provided by the utility model, which comprises an upper cover plate 1, a lower cover plate 2 and a pressure reducing throttle valve 3;
the upper cover plate 1 comprises a first notch and a second notch, the lower cover plate 2 comprises a third notch and a fourth notch, and the upper cover plate 1 is matched with the lower cover plate 2;
when the upper cover plate 1 is matched with the lower cover plate 2, the first gap and the third gap form a feed port 5, and the second gap and the fourth gap form a discharge port 6;
the lower cover plate 2 comprises a bracket 21, the upper cover plate 1 is provided with a vent hole 11, and the decompression throttle valve 3 is communicated with the vent hole 11 through a vent pipe.
Further, the feed inlet 5 and the discharge outlet 6 are provided with flexible sealing rings 4. Flexible sealing washer 4 has certain toughness and heat dispersion better, and flexible sealing washer 4 that has toughness can prevent to lead to mutual friction between the part because equipment vibration, and the heat that produces when the belt transmission band operates also can distribute through flexible sealing washer 4, prevents that high temperature from leading to feed inlet 5 or 6 structural deformations of discharge gate, reduces whole leakproofness.
Further, the lower housing plate 2 further comprises a buckle 22, the upper housing plate 1 further comprises a stop block 12 matched with the buckle 22, and the matching of the buckle 22 and the stop block 12 enables the upper housing plate 1 and the lower housing plate 2 to be matched together more stably.
Further, decompression throttle valve 3 is equipped with baroceptor 31 and audible-visual annunciator 32, and baroceptor 31 electric connection prevents that the damaged gas leakage phenomenon that appears of equipment, and the staff is difficult to discover in audible-visual annunciator 32.
The working principle is as follows:
the support 21 is attached to the ground to stabilize the whole lower cover plate 2, a belt transmission belt is placed in the lower cover plate 2, the upper cover plate 1 is placed again, the upper cover plate 1 is matched with the lower cover plate 2 to form a cavity, the belt transmission belt is located in the cavity, the air vent 11 and the decompression throttle valve 3 are connected through an air pipe, the decompression throttle valve 3 is started to inflate the cavity, the air pressure in the cavity is slightly larger than the atmospheric pressure, and external air is placed to enter the cavity to cause internal materials to be combusted or subjected to explosion reaction.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "upper", "lower", "left", "right" and the like are used herein for illustrative purposes only.
