Description

Technical Field

[0001] The utility model relates to the technical field of preparation of mortar interface agent, in particular to a temporary storage device which is convenient for sealing and unsealing. Background Technique

[0002] Wet-mixed mortar refers to a mortar mixture which is composed of cementitious materials, fine aggregates, admixtures, water and various components determined according to performance, proportioned in a certain ratio, metered and mixed in a mixing plant, transported to the use site by a mixing truck, stored in a special container and used up within a specified time. After the wet-mixed mortar is processed, it needs to be temporarily stored. The existing temporary storage devices are mostly simple sealed rubber barrels, which are troublesome to open and close and often have poor sealing performance.

[0003] The technical solution disclosed in the Chinese patent with the authorization announcement number of CN220722017U ensures the seal at the connection between the barrel cover and the barrel body by setting a sealing rubber ring, operating the operating mechanism, applying pressure to the sealing rubber ring through the pressing mechanism, and making the sealing rubber ring tightly abut against the inner side wall of the barrel body due to the applied pressure. Since the pressure can be freely adjusted in size, the sealing performance of the sealing rubber ring can be always maintained no matter how many times it is used, the service life of the device is improved, and the quality of the internally stored interface agent is ensured.

[0004] However, this device still has deficiencies: the service life of the sealing rubber ring is limited. Once the sealing rubber ring ages, the hydraulic oil inside it is likely to seep out and mix into the wet-mixed mortar, and the replacement difficulty of this kind of sealing rubber ring is greater than that of the traditional sealing strip.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] Embodiment 1

[0029] As Figures 1-6 shown, a temporary storage device for facilitating sealing and unsealing proposed by the present utility model includes a barrel body 1, a barrel cover 4, a convex block 6, a piston plate 9, and a driving mechanism. An annular gasket 3 coaxial with its inner cavity is provided on the inner wall of the barrel body 1. A buckle assembly 5 for locking the barrel cover 4 to the barrel body 1 is provided on the barrel cover 4. An annular skirt 2 is provided on the outer wall of the barrel body 1, and a buckle assembly 5 is provided on the barrel cover 4. The barrel cover 4 is connected to the barrel body 1 through the annular skirt 2 and the buckle assembly 5. The buckle assembly 5 includes a fixed seat 51, a handle 52, and a bolt 54. Two fixed seats 51 are symmetrically arranged on the barrel cover 4. The handle 52 is rotatably connected to the fixed seat 51, and a clamping block 53 that engages with the lower surface of the annular skirt 2 is provided on the handle 52. A jack 511 is provided on the fixed seat 51. A limiting groove is provided in the handle 52. A first spring rod 55 is provided in the limiting groove, and a side groove communicating with the limiting groove is provided on the side of the handle 52 away from the clamping block 53. One end of the bolt 54 is inserted into the jack 511, the other end is inserted into the limiting groove and connected to the movable end of the first spring rod 55. A dial plate 56 is provided on the side of the bolt 54, and the dial plate 56 extends outwards along the side groove and is slidably connected to the inner wall of the side groove. The fixed seat 51 is a U-shaped plate, and the opening of the U-shaped plate faces the barrel body. The handle 52 is located inside the opening of the U-shaped plate to limit the turning angle of the handle 52 through the crossbar of the U-shaped plate.

[0030] The convex block 6 is coaxially connected to the upper wall of the concave surface of the barrel cover 4. The outer diameter of the tip of the convex block 6 is not greater than the inner diameter of the annular gasket 3. A lap 61 coaxial with it is provided on the outer wall of the convex block 6, and a sealing gasket 7 that fits with the upper surface of the annular gasket 3 is provided at the bottom of the lap 61. A cylindrical groove 62 communicating with the outside is provided in the convex block 6, and a one-way intake pipe 8 that unidirectionally conducts the inner cavity of the barrel body 1 and the cylindrical groove 62 is provided at one end of the convex block 6 inserted into the barrel body 1. The piston plate 9 is located in the cylindrical groove 62 and is slidably connected to its inner wall. A one-way exhaust pipe 10 that unidirectionally conducts the cylindrical groove 62 and the outside is provided on the piston plate 9, and the pipe orifice of the one-way exhaust pipe 10 is offset from the pipe orifice of the one-way intake pipe 8.

[0031] The driving mechanism includes a reciprocating driving component and a ventilation component. The reciprocating driving component includes a reciprocating lead screw 11 and a rotating shaft 13. Both the reciprocating lead screw 11 and the rotating shaft 13 are rotatably connected to the barrel cover 4 and the bump 6. The reciprocating lead screw 11 and the rotating shaft 13 both penetrate through the piston plate 9 and are slidably connected thereto. Moreover, the shuttle of the reciprocating lead screw 11 is connected to the piston plate 9. A driven gear 12 is coaxially arranged on the reciprocating lead screw 11, and a driving gear 15 is coaxially arranged on the rotating shaft 13. The driving gear 15 meshes with the driven gear 12. Both the driven gear 12 and the driving gear 15 are located above the piston plate 9. The reciprocating driving component drives the piston plate 9 to reciprocate slidably, so as to realize the sealed connection between the barrel cover 4 and the barrel body 1 by reducing the air pressure inside the barrel body 1. The ventilation component conducts the outside and the inner cavity of the barrel body 1 in the working state. The ventilation component includes a spline shaft 16 and a sealing plug 17. A cylindrical cavity 131 is arranged inside the rotating shaft 13. A side hole 132 communicating the cylindrical cavity 131 and the inner cavity of the barrel body 1 is arranged on the side surface of the rotating shaft 13. Moreover, a spline hole 133 communicating with the cylindrical cavity 131 is arranged above the cylindrical cavity 131 inside the rotating shaft 13. The sealing plug 17 is arranged inside the cylindrical cavity 131 and is slidably connected to its inner wall. When the sealing plug 17 is in the upper part inside the cylindrical cavity 131, the sealing plug 17 blocks the side hole 132. The spline shaft 16 is inserted into the cylindrical cavity 131 along the spline hole 133 and is connected to the sealing plug 17. The outer wall of the spline shaft 16 is in damping sliding connection with the inner wall of the spline hole 133. An air inlet channel 161 is arranged on the spline shaft 16. One end of the air inlet channel 161 communicates with the outside, and the other end of the air inlet channel communicates with the side hole 132 when the second spring rod 18 is in a contracted state. One end of the spline shaft 16 extending out of the barrel cover 4 is connected to a crank 19.

[0032] In this embodiment, the wet-mixed mortar is loaded into the barrel body 1, and then the barrel cover 4 is covered on the barrel body 1. The two side handles 52 are rotated to be in a vertical state. At this time, the clamping blocks 53 on the two side handles 52 just bite with the lower surface of the annular skirt 2, and at this time, the bolt 54 is inserted into the jack 511 to prevent the handle 52 from automatically flipping. At this time, the crank 19 is directly rotated. The crank 19 drives the rotating shaft 13 to rotate. The rotating shaft 13 drives the reciprocating screw rod 11 to rotate through the meshing relationship between the driving gear 15 and the driven gear 12. The reciprocating screw rod 11 rotates to drive the piston plate 9 to slide up and down reciprocally. When the piston plate 9 rises to the high position, the air in the inner cavity of the barrel body 1 enters the cylindrical groove 62 along the one-way intake pipe 8. As the piston plate 9 slides down, the air in the cylindrical groove 62 is discharged along the one-way exhaust pipe 10, thereby reducing the air pressure in the barrel body 1. The barrel cover 4 is firmly connected to the barrel body 1 through the cooperation of the external high air pressure and the low air pressure in the barrel body 1, and further improves the sealing performance between the barrel cover 4 and the barrel body 1 through the sealing gasket 7. When the barrel cover 4 needs to be opened, the spline shaft 16 is pressed down to make the air intake channel 161 communicate with the inner cavity of the barrel body 1 and the outside. The outside air enters the barrel body 1 to make the air pressure inside and outside the barrel body 1 balanced. At this time, the dial 56 is pressed down, and then the bolt 54 is driven to slide down. The bolt 54 disengages from the jack 511 to release the rotation limit of the handle 52. After the handle 52 is flipped so that the clamping block 53 disengages from the annular skirt 2, the barrel cover 5 can be directly removed by lifting the handle 52.

[0033] Embodiment 2

[0034] As Figure 3 and Figure 5 shown, a temporary storage device for facilitating sealing and unsealing proposed by the present utility model, compared with Embodiment 1, a stirring paddle 14 is provided at one end of the rotating shaft 13 inserted into the barrel body 1.

[0035] In this embodiment, since the temporary storage time is uncertain, when the storage time is relatively long, the wet-mixed mortar is prone to the phenomenon of chromatography. When in use, the spline shaft 16 is pressed down to make the air intake channel 161 communicate with the outside and the inner cavity of the barrel body 1. At the same time, the crank 19 is rotated to drive the spline shaft 16 and the rotating shaft 13 to rotate, and then drive the stirring paddle 14 to rotate, and the wet-mixed mortar in the barrel body 1 is stirred by the stirring paddle to make it uniform.

[0036] Embodiment 3

[0037] As Figure 6 shown, a temporary storage device for facilitating sealing and unsealing proposed by the present utility model, compared with Embodiment 1, a second spring rod 18 with the movable end facing upward is provided on the lower wall of the cylindrical cavity 131, and the bottom of the sealing plug 17 is connected to the movable end of the second spring rod 18.

[0038] In this embodiment, the second spring rod 18 is used to push the sealing plug 17 upward, so as to prevent the inner compartment of the barrel 1 from automatically communicating with the outside after the sealing plug 17 freely falls.
