Description

A kind of hopper valve

Technical field

The utility model relates to a kind of hopper manually-operated gate technical field of especially big volume, specifically is a kind of hopper valve.

Background technique

In present production, life; A lot of large-scale storing hoppers are arranged, such as cement storage tank, foodstuff preservation jar, be used for bridge construction concrete hopper etc., because these hoppers are bulky; The quality in kind that stores is big, and existing hopper valve is difficult to open object is emitted; Simultaneously, in the hopper valve opening process, hopper valve is easy to generate difficult situation of closing at any time, has brought very big difficulty to depositing material object, and such hopper can only be deposited material object, but can not be easy to easily granular material object emitted.In addition, in valve opening and pass closed procedure, granular material is easy to get into the space between valve sidewall and the hopper, causes valve stuck, influences the normal open and close of valve, uses very inconvenience.

Summary of the invention

The purpose of the utility model is the defective that overcomes existing hopper valve, and a kind of opening and closing hopper valve flexibly is provided.

To achieve these goals, the hopper valve of the utility model design comprises hopper and the valve that is arranged on feed hopper bottom; Said valve comprises and is fixed on two fixed arms that laterally arrange of feed hopper bottom; The bottom of two fixed arms connects through a running shaft, and the two ends of said running shaft are separately installed with fan shape baffle, are connected with the valve dwang at least one fan shape baffle; The scallop of two fan shape baffles is connected through the cambered surface baffle plate; The discharge port end of hopper is connected with end baffle, and the both sides of end baffle are connected with the curved side baffle plate respectively, and the edge of curved side baffle plate is an arc; Said arc and cambered surface baffle plate arcuate shape match, and two fan shape baffles are inboard at two curved side baffle plates.

Preferably, right angle side is connected with the valve dwang on the longitudinal surface of each piece fan shape baffle.

The hopper valve of the utility model is installed in feed hopper bottom; The opening and closing of valve rely on fan shape baffle to rotate around running shaft and realize; The both sides of lateral retaining plate are separately installed with edge and the identical side plate of cambered surface baffle edge shape outside, make in opening and closing valve process do not have the slit between side plate and the fan shape baffle; Material can not fall between side plate and the fan shape baffle, valve opening with close flexibly; The valve dwang is set on valve, applies external force valve is rotated around running shaft, valve is adding under the external force effect, and opening and closing are flexible, use very convenient.

Embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to describe in detail:

Hopper valve as shown in Figure 1 comprises hopper 1 and the valve that is arranged on hopper 1 bottom, and valve comprises and is fixed on two fixed arms that laterally arrange 3 in hopper 1 bottom; The bottom of two fixed arms 3 connects through a running shaft 9, and the two ends of running shaft 9 are separately installed with fan shape baffle 4, and right angle side is connected with valve dwang 8 on the longitudinal surface of each piece fan shape baffle 4; The scallop of two fan shape baffles 4 is connected through cambered surface baffle plate 5; The discharge port end of hopper 1 is connected with end baffle 6, and the both sides of end baffle 6 are connected with curved side baffle plate 7 respectively, and the edge of curved side baffle plate 7 is an arc; Two fan shape baffles 4 are in two curved side baffle plates, 7 inboards; The edge arc of curved side baffle plate 7 and cambered surface baffle plate 5 arcuate shape match, and arcuate shape matches and specifically is meant, the edge of curved side baffle plate 7 is consistent with the cambered surface radian of cambered surface baffle plate 5 upper surfaces; And when valve closing; The upper surface of cambered surface baffle plate 5 is positioned at curved side baffle plate 7 inboards, and perhaps, cambered surface baffle plate 5 upper surface both sides and curved side baffle plate 7 internal surfaces fit.

The working principle of the utility model:

Hopper valve has been carried out mechanical analysis, consult shown in Figure 4, according to the stressed principle of hopper valve, hopper valve in the process of opening or closing mainly be above receiving material object to its frictional force F, F=u*N;

In the formula, F is the suffered frictional force of valve, and u is valve material and the friction factor of storage between the material object, and N is for storing the positive pressure to valve in kind, N=G*S wherein, and G is for storing gravity in kind, and S is for storing the effective area of contact to valve in kind.

According to above-mentioned loading characteristic, u is a kind of mechanics parameter intrinsic between the object, and it depends on the character of object itself, can't change.That can change is N, and N=G*S can be found out by formula, reduces N and need reduce S, and S is relevant with the baffle plate of hopper valve, and the utility model is a cambered plate with baffle design, and it is constant to make that S remains, and is in minimum state.In the process of Open valve; Must there be external force to resist the frictional force F that gathers materials to valve; One dwang 8 is set on valve, relies on external force rotated bar 8, cambered surface baffle plate 5 is rotarily opened and throttle down around running shaft 9; Valve opening state is as shown in Figure 3, and the valve closing state is as shown in Figure 2.

When W*L2.COS Ψ＞F*L 1, hopper valve is opened; Ψ is power and the arm of force angle with respect to running shaft; Cambered surface baffle plate 5 is the design of camber line face, and F*L1 is always definite value, increases W*L2, and hopper valve can be opened or close, flexible operation.

The utility model is fixed on dwang 8 on the peripheral hardware fixed arm 3; Gathering materials in hopper 1 is when falling; Be gathering materials of graininess can not produce crowded folder, solved the problem that granule materials squeezes folder, adopt the valve of the utility model in the hopper both sides; In the blowing process, can open and close at any time valve, the opening and closing state of valve is consulted Fig. 1 and Fig. 2.

The content of not doing in this specification to describe in detail belongs to related domain professional and technical personnel's known prior art.
