Technical field

The utility model belongs to pail pack field, more particularly, to a kind of pressure-relief explosion-proof bucket.

Background technique

Plastic barrel is widely used in storing strong corrosive, easily due to stronger Corrosion Protection, therefore by chemical plant Fire class and volatile liquid chemical product raw material；As Chinese patent CN2017204743017 discloses a kind of overpressure resistant and explosion-proof plastics Bucket, including staving, anti-extrusion packing layer, upper capping, bung hole sealing cover and relief hole, the bottom surface of the staving are equipped with lower capping, And the top of staving is equipped with upper capping, the central position of the upper capping is equipped with bung hole, and bung hole sealing is equipped on bung hole It covers, three groups of cross support bars is equipped between the inner wall of the staving, the inner sidewall of the staving is equipped with plastic liner, and in plastics The outside of wall is equipped with anti-extrusion packing layer, is coated with Anti-bumping protection shell, and Anti-bumping protection shell on the outside of the anti-extrusion packing layer Wrap around equipped with four groups of anti-explosion hoops, the gas inside staving cannot be discharged, the expansion of staving may finally be caused even Explosion.

Utility model content

Technical problem to be solved in the utility model is exactly to be in view of the deficiency of the prior art, to provide one kind Pressure-relief explosion-proof bucket.

The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of pressure-relief explosion-proof bucket, including staving, on Lid and pressure relief mechanism；The upper cover is mounted on the top of the staving；The pressure relief mechanism includes fixing seat, pressure release passage and pushes away Lever；The two sides of the fixing seat are fixed on the top of the upper cover and the inside of the staving, institute are goed deep into the lower part of fixing seat State the inside that pressure release passage is mounted on the fixing seat, the catch bar lower activity on the fixing seat, wherein the promotion Arc groove is provided on the two sides of bar, the bottom of the pressure release passage is provided with the ball being embedded in the arc groove.

Further, the upper cover is withheld in the upper end of the staving, and the upper cover and the staving contact position It installs and is equipped with Sealing shield ring.

Further, the ball is fixed on the fixing seat by spring.

Further, the radius of the arc groove is less than the radius of the ball.

Further, the top of the pressure release passage is provided with sealing valve, and pressure release passage plays bilayer by sealing valve The effect of sealing.

Further, the upper end of the catch bar is provided with squeeze grip.

Further, it is provided between the squeeze grip and the fixing seat by pressing spring.

Compared with prior art, the utility model has the beneficial effects that the inside of the staving holds liquid, the upper cover The staving is sealed, at this point, position of the arc groove far from ball, ball seal pressure release passage；It needs to arrange inside staving Out when gas, the catch bar is moved down, and arc groove is embedded in the ball, by between ball and the arc groove Gap, lodge in the intracorporal gas of the bucket pass through pressure release passage be discharged staving outside.It avoids by adopting the above technical scheme Industrial chemicals is in storage and transport as the raising of ambient temperature leads to the expansion for the chemical raw material barrel for holding liquid It even explodes, largely eliminates security risk.

Detailed description of the invention

Specific embodiment

The utility model is described in further detail below in conjunction with specific embodiment.It should be appreciated that described herein Specific embodiment is only used to explain the utility model, is not used to limit the utility model.

In the description of the present invention, it should be understood that term " center ", " longitudinal direction ", " transverse direction ", "upper", "lower", The orientation or positional relationship of the instructions such as "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outside" is It is based on the orientation or positional relationship shown in the drawings, is merely for convenience of describing the present invention and simplifying the description, rather than indicate Or imply that signified device or element must have a particular orientation, be constructed and operated in a specific orientation, therefore cannot understand For limitations of the present invention.

In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " is pacified Dress ", " connected ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or integrally Connection；It can be mechanical connection, be also possible to be electrically connected；Can be directly connected, can also indirectly connected through an intermediary, It can be the connection of two components interiors.For the ordinary skill in the art, on being understood by concrete condition State the concrete meaning of term in the present invention.

As shown in Figure 1, 2, a kind of pressure-relief explosion-proof bucket, including staving 1, upper cover 2 and pressure relief mechanism 3；The upper cover 2 is mounted on The top of the staving 1；The pressure relief mechanism 3 includes fixing seat 31, pressure release passage 32 and catch bar 33；The fixing seat 31 Two sides are fixed on the top of the upper cover 2 and the inside of the staving 1 is goed deep into the lower part of fixing seat 31, and the pressure release passage 32 is pacified Mounted in the inside of the fixing seat 31, the catch bar 33 is up and down in the fixing seat 31, wherein the catch bar 33 Arc groove 331 is provided on two sides, the bottom of the pressure release passage 32 is provided with the ball being embedded in the arc groove 331 321。

In use, the inside of the staving 1 holds liquid, the upper cover 2 seals the staving 1, at this point, arc groove 331 positions far from ball 321, ball 321 seal pressure release passage 32；When inside staving 1 needing that gas is discharged, such as Fig. 2 Shown, the catch bar 33 moves down, and arc groove 331 is embedded in the ball 321, passes through ball 321 and the circular arc The outside of staving 1 is discharged by pressure release passage 32 for gap between groove 331, the gas lodged in the staving 1.

The upper cover 2 is connect with the staving 1, and the upper cover 2 is withheld in the upper end of the staving 1, and the upper cover 2 1 contact position of staving is provided with Sealing shield ring (attached drawing is not shown)；Keep upper cover 2 and staving 1 complete by Sealing shield ring Sealing, prevents the gas in staving 1 from discharging.

The ball 321 is up and down, and the ball 321 is fixed in the fixing seat 31 by spring 311, ball 321 prevent it from shaking in pressure release passage 32 by 311 fixed party face of spring, on the other hand when catch bar 33 moves up When, spring 311 has certain tractive force to ball, and the position of arc groove 331 will not be followed mobile and moved up, to prevent from justifying Arc fluting 331 goes wrong with the sealing of ball 321, and the top of the pressure release passage 32 is provided with sealing valve 322, pressure release passage 32 Play the role of double-layer seal by sealing valve 322.

It is pressed down on for convenience of the catch bar 33, the upper end of the catch bar 33 is provided with squeeze grip 332.For side Toilet is stated catch bar 33 and is lifted up, and is provided between the squeeze grip and the fixing seat 31 by pressing spring 333.

Industrial chemicals is avoided by adopting the above technical scheme in storage and transport as the raising of ambient temperature is led It causes the expansion for holding the chemical raw material barrel of liquid even to explode, largely eliminates security risk.

Wherein, the fixing seat 31 in this programme, catch bar 33 can select according to the actual situation in the length of the staving 1 It selects.

The above is only the preferred embodiment of the utility model, it is noted that for the general of the art For logical technical staff, without departing from the principle of this utility model, several improvements and modifications can also be made, these change It also should be regarded as the protection scope of the utility model into retouching.
