Description

Technical Field

[0001] This invention relates to the field of glyphosate production equipment technology, and in particular to a mixing equipment for glyphosate production. Background Technology

[0002] Glyphosate (PMIDA) is a major raw material for the production of highly efficient, low-toxicity, broad-spectrum non-selective post-emergence herbicides. It is also an important intermediate in the pesticide, pharmaceutical, rubber, electroplating, and dye industries. In the production process of glyphosate, iminodiacetonitrile and inorganic acid are mixed and acidified in a reaction vessel. Then, water and iminodiacetic acid are added, and the mixture is alkalized with concentrated ammonia water with a mass fraction of 25-28% to adjust the pH to 1-3. After cooling, filtration, and crystallization, iminodiacetic acid is obtained. During this process, a reaction vessel is required for stirring.

[0003] The existing applications CN202421503143.X describe a stirring device for producing glyphosate and a reaction vessel for processing glyphosate. Both devices use a stirring mechanism to mix the raw materials of glyphosate. Although they can achieve mixing of the raw materials, the rotation trajectory of the stirring mechanism is fixed and its stirring range cannot be changed, resulting in poor mixing effect and failure to fully mix the raw materials. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mixing device for the production of glyphosate.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A mixing device for producing glyphosate includes a mixing tank, a discharge pipe connected to the lower side of the mixing tank, a rotating plate rotatably connected to the upper side inside the mixing tank, two rotating stirring components reciprocating below the rotating plate, a feed inlet on the rotating plate, a cover plate hinged to the upper side of the mixing tank, a drive device connected to the cover plate, and a drive rod of the drive device being snapped onto the rotating plate by an elastic snap-fit ​​component.

[0006] Preferably, two sliding grooves are provided on the lower side of the rotating plate, and a moving plate slides back and forth in each sliding groove, with the rotating stirring component connected to the lower side of the moving plate.

[0007] Preferably, a reciprocating lead screw is rotatably connected in each of the sliding grooves, and the reciprocating lead screw drives the moving plate through a threaded transmission, so that the moving plate moves back and forth by rotating the reciprocating lead screw.

[0008] Preferably, a gear is connected to the outer end of each reciprocating screw, and an annular rack is connected to the upper side inside the mixing box. The annular rack meshes with the gear, and the gear is driven to revolve by the rotating plate. The gear meshes with the annular rack, and the gear rotates, thereby driving the reciprocating screw to rotate. The reciprocating screw drives the moving plate to move back and forth, thereby driving the rotating agitator to move back and forth.

[0009] Preferably, the rotating stirring component includes a rotating shaft rotatably connected to the lower side of the moving plate, and stirring rods are evenly distributed on the rotating shaft to stir and mix the materials.

[0010] Preferably, a fixed toothed ring is sleeved on the outside of each of the rotating shafts, and a rack is connected to the lower side of the rotating plate. The rack meshes with the toothed ring, and when the rotating shaft moves, the toothed ring meshes with the transmission rack, thereby causing the toothed ring to drive the rotating shaft to rotate.

[0011] Preferably, an annular guide groove is provided on the outer side of the mixing box, an annular sliding plate is slidably connected in the annular guide groove, and the rotating plate is connected on the inner side of the annular sliding plate. The rotating plate rotates more smoothly and steadily by being guided and slid in the annular guide groove by the annular sliding plate.

[0012] Preferably, the elastic locking component includes an elastic telescopic rod, with a locking block connected to the end of the elastic telescopic rod. A locking groove is provided on the rotating plate, and the locking block is locked in the locking groove. Through the engagement of the locking block and the locking groove, the driving device can drive the rotating plate to rotate.

[0013] Preferably, a feed hopper is connected to the upper side of each feed inlet, which allows for better material delivery into the mixing tank through the feed inlet.

[0014] Preferably, a valve is connected to the discharge pipe to control the closure of the discharge pipe.

[0015] The advantages of this invention are as follows: When using the mixing equipment for glyphosate production provided by this invention, the cover is opened, and materials are fed into the mixing box through two feed hoppers. Then, the cover is closed, and a drive device on the cover drives a rotating plate to rotate. As the rotating plate rotates, it drives a gear to mesh and rotate on a ring rack, allowing the gear to rotate. The gear drives a reciprocating screw to rotate, which in turn drives a moving plate to move reciprocally. The moving plate then drives a rotating agitator to move reciprocally, thus expanding the mixing range. Furthermore, when the rotating agitator moves, the fixed gear ring on the rotating shaft meshes with the rack, causing the rotating shaft to drive the agitator rod to rotate, improving the mixing effect.

In this embodiment, the drive device 7 includes a reducer and a motor that are connected in a cooperative manner. The drive rod of the drive device 7 is locked to the rotating plate 3 via an elastic snap-fit ​​8.

[0021] The elastic snap-fit ​​component 8 includes an elastic telescopic rod 8.1, which is an existing structure. It includes a rectangular sleeve connected to the cover plate 6. A snap-fit ​​rod is inserted into the rectangular sleeve, and a spring is connected between the snap-fit ​​rod and the rectangular sleeve. A snap-fit ​​block 8.2 is connected to the end of the snap-fit ​​rod. A snap-fit ​​groove 9 is provided on the rotating plate 3, and the snap-fit ​​block 8.2 is snapped into the snap-fit ​​groove 9. The spring can make the snap-fit ​​block 8.2 tightly snapped into the snap-fit ​​groove 9, so that the driving device 7 can drive the rotating plate 3 to rotate.

[0022] A discharge pipe 2 is connected to the lower side of the mixing tank 1, through which the mixed material is discharged. A valve 2.1 is connected to the discharge pipe 2, and the opening and closing of the discharge pipe 2 is controlled by the valve 2.1.

[0023] Two sliding grooves 3.1 are provided on the lower side of the rotating plate 3, such as... Figure 3 As shown, a reciprocating sliding plate 3.2 is provided in each sliding groove 3.1. A bearing seat is connected to one side of each sliding groove 3.1, and a reciprocating screw 3.3 is inserted into the bearing seat. A through hole is provided on the other side of each sliding groove 3.1, through which the reciprocating screw 3.3 passes. A gear 3.4 is connected to the outside of each reciprocating screw 3.3. A ring rack 3.5 is connected to the upper side of the mixing box 1. The ring rack 3.5 meshes with the gear 3.4. When the rotating plate 3 drives the gear 3.4 to revolve, the gear 3.4 meshes with the ring rack 3.5, and the gear 3.4 drives the reciprocating screw 3.3 to rotate. A corresponding threaded through hole is provided on the sliding plate 3.2, and the threaded through hole is threadedly connected to the reciprocating screw 3.3, so that the reciprocating screw can drive the sliding plate 3.2 to move back and forth.

[0024] The rotating agitator 4 is connected to the lower side of the moving plate 3.2. The rotating agitator 4 includes a rotating shaft 4.1, which is rotatably connected to the lower side of the moving plate 3.2. That is, a circular box 3.6 is connected to the lower side of the moving plate 3.2. A limiting plate is rotatably connected inside the circular box 3.6. A through hole is provided on the lower side of the circular box 3.6, and the corresponding rotating shaft 4.1 is inserted into the through hole.

Agitating rods 4.2 are evenly distributed on the rotating shaft 4.1. The rotating shaft 4.1 drives the agitating rods 4.2 to rotate, thereby stirring and mixing the materials.

[0025] A fixed gear ring 4.3 is fitted onto the outside of each rotating shaft 4.1. A rack 4.4 is connected to the lower side of the rotating plate 3.2. The rack 4.4 meshes with the gear ring 4.3. When the rotating shaft 4.1 moves, the gear ring 4.3 meshes with the rack 4.4, allowing the gear ring 4.3 to rotate, thereby driving the rotating shaft 4.1 to rotate. The rotating shaft 4.1 then drives the stirring rod 4.2 to rotate.

[0026] Working principle: During mixing, the cover plate 6 is first opened, and then the material is fed into the mixing box 1 through the feed hopper 5.1. Then the cover plate 6 is closed, so that the locking block 8.2 can be locked into the locking groove 9. The driving device 7 drives the locking block 8.2 to rotate. The locking block 8.2 drives the rotating plate 3 to rotate through the locking groove 9. The rotating plate 3 drives the two rotating stirring parts 4 to revolve. When the rotating plate 3 rotates, it drives the gear 3.4 to revolve. The gear 3.4 meshes with the ring rack 3. 5. Gear 3.4 drives reciprocating screw 3.3 to rotate, which in turn drives two rotating agitators 4 to reciprocate, thereby changing the revolution trajectory of the rotating agitators 4, increasing the mixing range. When the rotating agitators 4 reciprocate, the gear ring 4.3 on the rotating shaft 4.1 meshes with the rack 4.4, allowing the gear ring 4.3 to rotate, which in turn drives the rotating shaft 4.1 to rotate. The rotating shaft 4.1 drives the agitator rod 4.2 to rotate, thereby mixing the materials and improving the mixing effect.
