Description

Technical Field

[0001] This utility model relates to the field of magnesium hydroxide storage technology, specifically a magnesium hydroxide storage moisture-proof box. Background Technology

[0002] Magnesium hydroxide is an inorganic compound, appearing as a white powder. It is insoluble in water but soluble in dilute acids and ammonium salt solutions. It has a wide range of applications in industry, such as as a flame retardant because it absorbs a large amount of heat during decomposition and the water vapor produced can dilute flammable gases, thus playing a flame-retardant role. It can also be used in wastewater treatment to neutralize acidic wastewater and remove heavy metal ions. In medicine, it can also be used as an antacid to neutralize stomach acid and relieve discomfort caused by excessive stomach acid.

[0003] Currently, magnesium hydroxide, as an important chemical raw material, is prone to deliquescence during storage due to its easy absorption of moisture from the air, which severely affects its performance and quality. However, the existing moisture-proof design of storage boxes has obvious shortcomings: especially when taking out magnesium hydroxide, the box door must be opened to connect the inside with the outside. At this time, the outside humid air will quickly enter the box. Even if the operation time is short, it will still cause the humidity inside the box to rise, which will cause the magnesium hydroxide to become damp and deteriorate. Therefore, it is urgent to design a moisture-proof storage box for magnesium hydroxide to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a moisture-proof storage box for magnesium hydroxide to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

A dehumidifying component inserted into the feed pipe is provided at the bottom of the sealing cover. A discharge frame is fixedly installed at the bottom of the inner box, and through holes are provided on both sides of the discharge frame and one side of the outer box. The bottom of one side of the outer wall of the inner box and the bottom of one side of the inner wall of the outer box are connected. A connecting pipe is fixed between the parts, and the same discharge rod is inserted into the inner wall of the connecting pipe and the inner wall of the through hole. A push-pull mechanism for driving the discharge rod is provided between the outer box and the inner box, and an agitator is provided on the inner box and the push-pull mechanism. A material picking groove is opened on the discharge rod, and inclined seats that fit against the outer wall of the discharge rod are fixedly installed on the inner walls of both ends of the feeding frame. Annular sealing grooves are opened on both sides of the outer wall of the discharge rod, and sealing gaskets are fixedly installed on the inner walls of the annular sealing grooves. The sealing gaskets are tightly attached to the inner walls of the connecting pipe and the through hole.

[0007] Furthermore, the dehumidification assembly includes multiple connecting rods fixed to the bottom of the sealing cover, and a dehumidification box is fixedly installed at the bottom of the connecting rods. The dehumidification box contains a desiccant, and multiple ventilation holes are opened at the bottom of the dehumidification box. A handle is fixed to the top of the sealing cover.

[0008] Furthermore, the push-pull mechanism includes a threaded rod rotatably connected to the inner wall of the other side of the outer housing and the outer wall of the other side of the inner housing. A forward and reverse motor for driving the threaded rod to rotate is fixedly installed on the outer wall of the other side of the outer housing. A movable seat is screwed to the outer wall of the threaded rod, and a connecting groove is opened at one end of the discharge rod. A push-pull rod inserted into the connecting groove is fixedly installed at the bottom of one side of the movable seat. A tension spring is fixedly installed at one end of the push-pull rod and one end of the connecting groove. A guide hole is opened on the movable seat, and a guide rod passing through the guide hole is fixed between the inner wall of the other side of the outer housing and the outer wall of the other side of the inner housing.

[0009] Furthermore, the agitation assembly includes a mounting base fixed to the inner wall of the bottom of the inner box, and mounting holes are provided at the middle of the mounting base and the bottom of the inner box. An agitation shaft is rotatably connected to the inner wall of the mounting hole through a sealed bearing. Spiral agitation blades are fixedly installed on the outer wall of the agitation shaft. Bevel gears are fixedly installed at the bottom end of the agitation shaft and on the outer wall of the threaded rod, and the two bevel gears mesh with each other.

[0010] Furthermore, one end of the discharge rod is fixedly installed with an end cover plate that fits against the outer wall of one side of the outer casing, and a discharge pipe is fixedly installed at the bottom of one side of the outer casing.

[0011] Furthermore, multiple electric heating plates are fixedly installed on the inner wall of the outer casing, and a detection port is opened on one side of the outer casing.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model uses a double-box design of outer and inner boxes to form an isolated space, reducing the direct intrusion of external moisture. The top of the inner box is tightly sealed with a sealing cover and sealing strip, and the dehumidification component continuously absorbs internal moisture to maintain a low humidity environment.

[0015] This invention utilizes the linkage between an electric heating plate and a humidity sensor to monitor the humidity inside the chamber in real time. When the humidity exceeds the standard, it automatically starts heating to remove moisture, further enhancing the moisture-proof effect and preventing magnesium hydroxide from deliquescing due to moisture absorption.

[0016] This invention employs a push-pull discharge structure. A reversible motor drives the threaded rod, moving seat, and discharge rod to move, allowing for the quantitative dispensing of magnesium hydroxide via a dispensing trough. This eliminates the need to open the box door, preventing the entry of humid air during dispensing. Furthermore, the contact points between the discharge rod and the connecting pipe / through hole are sealed with gaskets and annular sealing grooves, allowing for rapid restoration of the box's airtightness after dispensing, minimizing the risk of moisture intrusion. This fully enclosed storage and dispensing system fundamentally solves the humidity fluctuation problem caused by frequent opening of traditional storage boxes, effectively preventing magnesium hydroxide from becoming damp and deteriorating, ensuring its chemical properties and quality of use, and reducing economic losses due to material failure.

[0017] In this invention, the stirring component operates synchronously during material collection, preventing magnesium hydroxide from accumulating and clogging, and ensuring smooth material discharge. Attached Figure Description

Thus, through fully sealed storage and dispensing, the problem of humidity fluctuation caused by frequent opening of traditional storage boxes is solved, effectively preventing magnesium hydroxide from becoming damp and deteriorating.

[0027] Specifically, multiple electric heating plates 15 are fixedly installed on the inner wall of the outer casing 1, and a detection port is opened on one side of the outer casing 1.

[0028] Specifically, a support frame 6 is fixedly installed at the bottom of the outer casing 1, and casters are fixedly installed at the four corners of the bottom of the support frame 6. The casters and the support frame 6 facilitate the movement and fixation of the equipment, making it suitable for different working scenarios.

[0029] The working principle of this utility model is as follows: During storage, magnesium hydroxide is added to the inner box 9 through the feed pipe 2, the sealing cover 3 is closed, and the sealing strip 20 ensures that the feed pipe 2 is sealed. Secondly, the desiccant in the dehumidification box 16 absorbs the moisture in the inner box 9 through the vent 21. At the same time, the humidity sensor 4 monitors the humidity in real time. If the humidity exceeds the standard, the controller 8 starts the electric heating plate 15 to heat and remove moisture.

[0030] During the retrieval phase, the controller 8 starts the forward and reverse motor 51, which drives the threaded rod 52 to rotate. The moving seat 53 moves along the guide rod 55 and pushes the discharge rod 11 through the push-pull rod 54. When the threaded rod 52 rotates, the bevel gear 102 drives the stirring shaft 103 to rotate. The spiral stirring blade 104 stirs the magnesium hydroxide in the inner box 9, causing it to fall into the feeding frame 18 and be guided into the picking trough 12 through the inclined seat 22. When the discharge rod 11 moves to the point where the picking trough 12 is aligned with the discharge pipe 7, the magnesium hydroxide is discharged through the discharge pipe 7. After the retrieval is completed, the forward and reverse motor 51 reverses, the moving seat 53 resets, the tension spring 56 pulls the discharge rod 11 back to its original position, and the sealing gasket 23 cooperates with the annular sealing groove 24 to ensure the sealing of the connecting pipe 14 and the through hole 19. The end cover plate 13 fits against the outer wall of the outer box 1, restoring the overall sealed state.
