One of the preferred embodiments of the present application, as shown in fig. 1 to 10, is a chemical reaction kettle, comprising a tank 1, a driving mechanism 2 and a plate assembly 3; the inside of the tank body 1 is sequentially provided with a first cavity section, a second cavity section and a discharge pipe from top to bottom; the first cavity section is cylindrical, the second cavity section is funnel-shaped, and the discharge pipe is arranged at the center of the bottom of the second cavity section; the driving mechanism 2 is arranged at the center of the tank body 1, and the plate assembly 3 is connected with the driving mechanism 2 in a matching way.
Specifically, when the plate assembly 3 is driven by the driving mechanism 2 to be located at the upper position of the tank body 1, the plate assembly 3 can be matched with the tank body 1 to be far away from the inner wall of the first cavity section, so that rotation stirring is carried out along with the driving mechanism 2; it will be appreciated that when the plate assembly 3 is in the uppermost position, the plate assembly 3 may be rotated to mix and agitate the raw materials of the reactor; at this time, the driving mechanism 2 performs the first operation.
When the plate assembly 3 is driven by the driving mechanism 2 to rotate and move downwards, the plate assembly 3 can move downwards in a way of keeping fit with the first cavity section and the second cavity section, so that the surplus materials adhered to the first cavity section and the second cavity section are scraped to the discharge pipe for discharge; it can be appreciated that when the driving mechanism 2 performs the second action, the plate assembly 3 can move down the inner wall of the reaction kettle, and in the process of moving down, the inner wall of the reaction kettle can be scraped, and then the inner part and the bottom position of the reaction kettle are automatically cleaned, so that the cleaning efficiency is improved.
It should be noted that, in the existing reaction kettle, only stirring blades are generally installed, that is, the driving mechanism 2 can only be used for rotating the stirring blades, so as to stir the raw materials in the reaction kettle. The reaction kettle is cleaned manually or a scraping mechanism is additionally arranged; the arrangement of the scraping mechanism may lead to complex internal structure of the reaction kettle and easy interference among mechanisms. Meanwhile, as the reaction kettle is convenient for discharging after raw material stirring, the bottom is generally required to be provided with a conical surface or an arc-shaped structure, namely a second cavity section. In the prior art, even if the scraping mechanism is arranged, scraping is generally carried out on the inner wall of the first cavity section in the circumferential shape. In the present embodiment, the two functions of stirring and scraping are integrated into the plate assembly 3; when the plate assembly 3 is positioned above the interior of the tank body 1, the plate assembly 3 can be driven by corresponding structures to be positioned between the first cavity section and the driving mechanism 2 and rotationally stir the driving mechanism 2; and when the raw materials stirring in the tank body 1 is completed and the inner wall of the tank body 1 needs to be scraped, the plate assembly 3 can be in contact with the first cavity section and the second cavity section inside the tank body 1 through corresponding structures in the downward moving process, and then all scraping and cleaning of the inner wall of the tank body 1 can be realized. Therefore, the complexity of the internal structure of the tank body 1 can be effectively reduced while the cleaning effect is improved, so that the stirring resistance is reduced to improve the stirring efficiency.
In the present embodiment, as shown in fig. 1, the drive mechanism 2 includes a rotating device 201 and a drive shaft 202; the rotating device 201 is arranged at the top of the tank body 1, and the driving shaft 202 axially penetrates through the center of the tank body 1 and is connected with the output end of the rotating device 201; the plate assembly 3 is coupled to the driving shaft 202 by the coupling 5, and the plate assembly 3 is coupled to the inside of the can 1 by the guide structure 4.
Specifically, when the rotating device 201 drives the driving shaft 202 to rotate forward (the driving mechanism 2 performs the first action), the plate assembly 3 can move up to the upper part of the tank body 1 through the guiding structure 4 and perform the constant-height circumferential rotation, so as to mix and stir the raw materials in the reaction kettle.
When the rotating device 201 drives the driving shaft 202 to reversely rotate (the driving mechanism 2 performs a second action), the plate assembly 3 can rotate and move downwards through the guide structure 4; it can be appreciated that the plate assembly 3 can move downwards in a spiral manner through the guide structure 4, so that the inner wall of the reaction kettle is scraped, and automatic cleaning is realized.
The rotating device 201 is a common general knowledge of a person skilled in the art, and a motor, a rotary hydraulic cylinder, or the like is common.
In this embodiment, as shown in fig. 2 and 3, the guide structure 4 includes a spiral groove 401 and an annular groove 402 provided on the inner wall of the first cavity section, and a guide block 403 elastically slidably mounted to the plate assembly 3; the annular groove 402 is located above the spiral groove 401 and communicates with the spiral groove, and the depth of the annular groove 402 in the circumferential forward direction becomes gradually shallower at the communicating position, and the sliding direction of the guide block 403 is along the radial direction of the can body 1.
When the driving shaft 202 rotates positively under the action of the rotating device 201, the plate assembly 3 can slide along the spiral groove 401 by the guide block 403 to lift axially until the guide block 403 is positioned in the annular groove 402 and slides positively, and the plate assembly 3 can rotate positively with unchanged height; it will be appreciated that the guide block 403 may rotate along the annular groove 402, and when the guide block 403 passes through the communication position between the annular groove 402 and the spiral groove 401, that is, the guide block 403 moves from a high position to a low position, and the guide block 403 is elastically slidably mounted, so that the guide block 403 always abuts against and cooperates with the annular groove 402, and the plate assembly 3 rotates synchronously with the driving shaft 202.
When the driving shaft 202 rotates reversely under the action of the rotating device 201, that is, when the guide block 403 passes through the communication position of the annular groove 402 and the spiral groove 401, the guide block 403 moves from a low position to a high position, and the high position has a blocking effect on the guide block 403, so that the guide block 403 transits from the low position, that is, the annular groove 402 slides to the spiral groove 401, and then the plate assembly 3 is driven to move spirally downwards.
It should be noted that the driving shaft 202 has various structural forms, including but not limited to the following two types:
structure one: as shown in fig. 6, the driving shaft 202 is a threaded rod (screw rod) 2021, and the connecting member 5 is in threaded engagement with the driving shaft 202, and it should be noted that the pitch of the spiral groove 401 is larger than that of the driving shaft 202, so that the plate assembly 3 can be spirally lifted or lowered.
And (2) a structure II: as shown in fig. 7, the driving shaft 202 is a spline shaft 2022, and the coupling 5 is spline-connected to the driving shaft 202, that is, the coupling 5 can slide up and down along the driving shaft 202.
Of course, the first structure and the second structure can meet the actual requirements, and the person skilled in the art can select according to the actual situation.
In this embodiment, as shown in fig. 3, the connecting piece 5 includes a connecting sleeve 501 and a first supporting rod 502; the connecting sleeve 501 is used for being matched with the driving shaft 202, and the first supporting rod 502 is fixedly arranged on the connecting sleeve 501 along the radial direction of the tank body 1; the panel assembly 3 comprises a first panel 301 and a second panel 302; the first plate 301 is fixed at the end position of the first supporting rod 502, and the first plate 301 can be attached to the inner wall of the first cavity section; the first supporting rod 502 can be elastically and slidably provided with the supporting component 6 through a spring, the second plate 302 can be hinged with the supporting component 6, and the supporting component 6 is matched with the top of the tank body 1 through a deflection structure.
Specifically, when the plate assembly 3 moves up and down spirally along the axial direction of the driving shaft 202, the first plate 301 is always attached to the inner wall of the first cavity section, so as to scrape the inner wall of the reaction kettle; when the plate assembly 3 is positioned at the upper part of the tank body 1, the second plate 302 can be driven by the deflection structure to be far away from the side wall of the first cavity section; it will be appreciated that when the second plate 302 is at the uppermost position, the second plate 302 may rotate to mix and stir the raw materials in the reaction kettle, so that the second plate 302 acts as a stirring rod to mix and stir the materials in the reaction kettle, and the second plate 302 needs to be far away from the inner wall of the reaction kettle, so as to reduce friction resistance generated during stirring.
When the plate assembly 3 is far away from the upper portion of the can 1 (when screwing down), the support assembly 6 can perform a first process and a second process; wherein, the first process: the support component 6 can slide along the first support rod 502, so as to drive the second plate 302 to move to contact or approach the inner wall of the first cavity section; the second process is as follows: the second plate 302 moves down with the connecting sleeve 501 in a spiral manner until being attached to the second cavity section (i.e. the funnel-shaped bottom) and moves down in a spiral manner, so as to scrape the bottom of the reaction kettle.
In this embodiment, as shown in fig. 3, the support assembly 6 includes a support 601, a second support bar 602, and a third support bar 603; the supporting piece 601 is elastically and slidably mounted on the first supporting rod 502 through a spring; the second support rod 602 and the third support rod 603 are both obliquely arranged, and the second support rod 602 and the third support rod 603 are both matched with the support member 601; the second support bar 602 is located below the support 601 for hinging the second plate 302, and the third support bar 603 is located above the support 601 and is press-fitted with the top of the tank 1 to form a dislocated structure.
Specifically, when the third support rod 603 extrudes the top of the tank body 1, the third support rod 603 can drive the second support rod 602 to drive the second plate 302 to move away from the inner wall of the first cavity section, so that the second plate 302 is spaced from the inner wall of the reaction kettle.
It should be noted that, the second support bar 602 and the third support bar 603 are installed in various manners, and the following two embodiments are shown:
mode one (not shown): the second support bar 602 and the third support bar 603 are fixedly installed on the support 601, and a wedge surface (not shown) is provided at the top of the can 1; it can be understood that when the third supporting rod 603 presses against the wedge surface, the third supporting rod 603 can drive the supporting member 601 to move axially along the first supporting rod 502 away from the inner wall of the first cavity section, and then the second supporting rod 602 drives the second plate 302 to move synchronously; that is, the second plate 302 can be moved away from the inner wall of the reaction vessel by the pressing of the wedge surface.
