Description

Technical Field

[0001] This utility model relates to the field of raw material mixing technology, specifically to a raw material mixing device for chemical production. Background Technology

[0002] Chemical raw materials refer to all kinds of raw materials used in the chemical industry. They can generally be divided into two categories: organic chemical raw materials and inorganic chemical raw materials. In the chemical production process, the mixing quality of raw materials has a direct impact on the performance and quality of the final product. A Chinese utility model patent (announcement number: CN222518411U) discloses a stirring device for mixing chemical raw materials. By setting up a shell, hinges, screens, handles, and baffles, when feeding raw materials, the raw materials are first poured into the screen. At this time, the raw materials that meet the requirements fall from the screen into the mixing tank. Then, the handle is pulled, and the handle drives the screen to rotate through the hinges. At this time, the larger particles of raw materials on the screen fall into the receiving hopper, which facilitates the subsequent crushing operation. This achieves the screening of raw materials and avoids crushing of raw materials that meet the standards, thus avoiding the problem of affecting the crushing efficiency.

[0003] However, the above-mentioned device still has some shortcomings in use. Specifically, after the raw materials are poured onto the screen, they tend to clump together, which not only clogs the screen mesh but also hinders the full contact between the upper raw materials and the screen. This makes it impossible for a large amount of raw materials to pass through the screen in time, requiring frequent manual intervention to clean the screen, which increases labor intensity. Therefore, in view of the above situation, a raw material mixing device for chemical production is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a raw material mixing device for chemical production. Through the structural design of rotating shaft, eccentric plate, connecting shaft and belt, the speed of raw material passing through screen is accelerated. Compared with the existing method of relying solely on gravity screening, the raw material screening time is greatly shortened. It can also shake off raw material particles attached to the gaps in the screening frame in time, avoiding the clogging of the screening frame due to raw material accumulation, and solving the problems of low screening efficiency and easy clogging.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model relates to a raw material mixing device for chemical production, comprising a frame, a mixing tank fixed to the top of the frame, a shell and a crushing device with a rotating shaft respectively disposed on the mixing tank, a screening frame hinged to the top of the shell, a striking mechanism disposed on one side of the inner wall of the shell, the striking mechanism comprising a rotating shaft rotating on one side of the inner wall of the shell, an eccentric plate fixed on the rotating shaft, one end of the rotating shaft extending out of the shell, a connecting shaft fixed to one end of the rotating shaft, the connecting shaft being connected to the end of the rotating shaft extending out of the shell via a belt drive, a limiting mechanism disposed on the outer wall of the shell, and a positioning block disposed on one side of the screening frame, the positioning block cooperating with the limiting mechanism when the screening frame is placed horizontally.

[0007] Furthermore, a fixing plate is fixed to the inner wall of the shell, and a first spring is fixed to the fixing plate, with the top of the first spring abutting against the bottom of the screening frame.

[0008] Furthermore, a through hole is provided on the outer wall of the housing, and the through hole is clearance-fitted with the rotating shaft.

[0009] Furthermore, the positioning block is L-shaped and has a positioning groove.

[0010] Furthermore, the limiting mechanism includes a mounting plate, which is fixed to the housing. The mounting plate has a slot and a groove. One side of the inner wall of the groove has an opening that connects to the slot. A sliding block slides in the groove. A limiting rod is fixed to one end of the sliding block. One end of the limiting rod passes through the opening and extends into the positioning groove. A second spring is fixed in the groove. One end of the second spring is fixed to the sliding block.

[0011] Furthermore, a guide rod is horizontally fixed inside the groove, the sliding block is L-shaped, and a round hole is opened on the guide rod, with the round hole and the guide rod having a clearance fit.

[0012] This utility model has the following beneficial effects:

[0013] This invention, through its structural design of a rotating shaft, eccentric plate, connecting shaft, and belt, allows the eccentric plate to rotate and periodically strike the bottom of the screening frame while the crushing device is crushing larger particles. This adds mechanical vibration to the material on the screening frame in addition to its own weight, accelerating the speed at which the material passes through the screen. Compared to existing methods that rely solely on gravity for screening, this significantly shortens the screening time and promptly shakes off material particles adhering to the pores of the screening frame, preventing blockage caused by material accumulation.

[0014] This utility model, through the structural design of positioning blocks and limiting mechanisms, can ensure that the screening frame is in a stable state during the screening process, thereby ensuring the smooth progress of the screening process.

[0015] Of course, it is not necessary for any product implementing the present utility model to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

SPECIFIC EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figure 1-4 , the present utility model provides a technical solution: a raw material mixing device for chemical production, including a frame body 1, a stirring barrel 2 is fixed on the top of the frame body 1, a housing 4 and a crushing device 3 with a rotating shaft 30 are respectively arranged on the stirring barrel 2, the top of the housing 4 is hinged with a screening frame 5 through a hinge, the screening frame 5 includes a square frame and a screen arranged on the frame, and a "C" - shaped baffle is arranged on the frame.

[0023] The bottom of the stirring barrel 2 has a discharge port, and the discharging method is the same as that of the prior art, so it will not be elaborated here.

[0024] Among them, the composition structure of the crushing device 3 is the same as that of the prior art, so it will not be elaborated here. There is a gap between the crushing device 3 and the housing 4, which can be used for the assembly of the connecting shaft 8.

[0025] The bottom of the shell 4 and the crushing device 3 are both connected to the inside of the mixing tank 2. The mixing tank 2 is equipped with a horizontally placed stirring rod and stirring blades on the stirring rod. The stirring rod is fixedly connected to the external motor output shaft.

[0026] A striking mechanism is provided on one side of the inner wall of the housing 4. The striking mechanism includes a rotating shaft 6 that rotates on one side of the inner wall of the housing 4. An eccentric plate 7 is fixed on the rotating shaft 6. The eccentric plate 7 is generally in the shape of an elliptical disk. One end of the rotating shaft 6 extends out of the housing 4. A through hole is provided on the outer wall of the housing 4. The through hole is clearance-fitted with the rotating shaft 6. A connecting shaft 8 is fixed to one end of the rotating shaft 30. The connecting shaft 8 is connected to the end of the rotating shaft 6 that extends out of the housing 4 via a belt 9.

[0027] Both the connecting shaft 8 and the rotating shaft 6 are fixed with pulleys, and a belt 9 is provided between the two pulleys.

[0028] When the crushing device 3 is started, the rotating shaft 30 begins to rotate, driving the crushing roller to crush large particles of raw materials. Through the transmission of the connecting shaft 8 and the belt 9, the rotating shaft 6 is driven to rotate synchronously. Due to the eccentricity of the eccentric plate 7, the eccentric plate 7 will generate a periodically changing centrifugal force during the rotation of the rotating shaft 6, causing the edge of the eccentric plate 7 to intermittently hit the bottom of the screening frame 5. This intermittent knocking action can produce a vibration effect on the raw materials accumulated on the screening frame 5. On the one hand, it speeds up the speed of the raw materials passing through the screen and improves the screening efficiency. On the other hand, it shakes off the raw material particles that are blocking the screen holes in time, prevents the screen from clogging, and ensures the smooth progress of the screening process.

[0029] The outer wall of the shell 4 is provided with a limiting mechanism 12, and a positioning block 50 is provided on one side of the screening frame 5. The positioning block 50 is L-shaped and has a positioning groove 51. When the screening frame 5 is placed horizontally, the positioning block 50 and the limiting mechanism 12 cooperate with each other.

[0030] The limiting mechanism 12 includes a mounting plate 120, which is fixed to the housing 4. The mounting plate 120 has a slot 121 and a groove 122. One side of the inner wall of the groove 122 has an opening 123 that communicates with the slot 121. A sliding block 124 slides in the groove 122. A limiting rod 127 is fixed to one end of the sliding block 124. One end of the limiting rod 127 passes through the opening 123 and extends into the positioning groove 51. A second spring 125 is fixed in the groove 122. One end of the second spring 125 is fixed to the sliding block 124.

[0031] A guide rod 126 is horizontally fixed inside the groove 122. The sliding block 124 is L-shaped. A round hole is provided on the guide rod 126, and the round hole is clearance-fitted with the guide rod 126.

[0032] When the screening frame 5 is placed horizontally on the top of the housing 4, the positioning block 50 is locked in the corresponding slot 121, and the limiting rod 127 passes through the opening 123 and is inserted into the positioning groove 51, thereby limiting and fixing the screening frame 5 to the housing 4, preventing the screening frame 5 from being displaced due to the impact of the striking mechanism or the impact of the raw material during the screening process, and ensuring the stability and reliability of the screening work. When it is necessary to clean the large particles of raw material remaining on the screening frame 5, the operator only needs to pull the sliding block 124 outward to overcome the elastic force of the second spring 125 and make the limiting rod 127 exit from the positioning groove 51, thereby releasing the limitation on the screening frame 5. By rotating the screening frame 5, the large particles of raw material slide into the crushing device 3.

[0033] A fixing plate 10 is fixed to the inner wall of the housing 4, and a first spring 11 is fixed on the fixing plate 10. The top of the first spring 11 abuts against the bottom of the screening frame 5.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
