Description

Technical Field

[0001] The invention relates to the technical field of slurry adding devices, in particular to a slurry adding device for a wet granulator. Background Art

[0002] The wet granulator is used to grind the wet powder into the required particles, and can also crush the block dry material into the required particles. The main features are that the screen is easy to install and disassemble, and the tightness can be adjusted appropriately. The seven-cornered roller is easy to disassemble and clean. The mechanical transmission system is completely enclosed in the machine body and is equipped with a lubrication system. The whole machine runs smoothly. The slurry adding mechanism of the wet granulator is very important.

[0003] With the rapid development of society, the use of wet granulators is becoming more and more frequent, and the quality requirements for the slurry adding mechanism, which is very important inside the wet granulator, are also increased accordingly. However, the slurry adding mechanism of the existing wet granulator cannot control the amount of slurry added very well, which greatly affects the working efficiency of the granulator and the quality of the finished product. In the related technology, the weight of the slurry can be detected in real time through the pressure sensor. When the detection result reaches the set value, it transmits the signal to the controller, and the controller immediately turns off the suction pump and the second electric control valve to prevent the slurry from flowing back. Then, the first electric control valve is controlled to open, so that the slurry enters the granulator for processing. Although the amount of slurry added can be strictly controlled to ensure the quality of the product, in actual use, the slurry remaining on the inside of the container and the pressure sensor will affect the normal monitoring of the pressure sensor, resulting in unstable addition of the slurry adding mechanism, which has certain limitations and is inconvenient to use.

[0034] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0035] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0036] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.

[0037] In addition, in this application, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0038] With the rapid development of society, the use of wet granulators is becoming more and more frequent, and the quality requirements for the slurry adding mechanism, which is very important inside the wet granulator, are also increasing. However, the slurry adding mechanism of the existing wet granulator cannot control the amount of slurry added well, which greatly affects the working efficiency of the granulator and the quality of the finished product.

[0039] In the related art, the weight of the slurry can be detected in real time through a pressure sensor. When the detection result reaches the set value, it transmits a signal to the controller, which then shuts down the suction pump and closes the second electrically controlled valve to prevent the slurry from flowing back. The controller then controls the opening of the first electrically controlled valve to allow the slurry to enter the granulator for processing. Although the amount of slurry added can be strictly controlled to ensure the quality of the product, in actual use, the slurry remaining on the inside of the container and on the pressure sensor will affect the normal monitoring of the pressure sensor, resulting in unstable addition of the slurry adding mechanism. This has certain limitations and is inconvenient to use.

[0040] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a slurry adding device for a wet granulator. When it is needed, the prepared slurry only needs to be transported into the shell 33 by a suction pump, the total amount of loading is detected by the pressure sensor 35, and finally the electric push rod 37 is turned on to realize loading. At the same time, the inside of the shell 33 can be cleaned by the push rod 44, so as to ensure the accuracy of the total amount of loading, which is more convenient and quick, and improves the convenience of the device.

[0041] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0042] Combination Figure 1-Figure 4The embodiment of the present application provides a slurry adding device for a wet granulator, comprising a granulator body 1, a feed hopper 2 is provided at its feed port, and a metering assembly 3 is provided at the top of the feed hopper 2; the metering assembly 3 comprises: a ring body 1 31 is fixedly connected to the top of the feed hopper 2; a ring body 2 32 is slidably connected to the inner side of the ring body 1 31; a shell 33 is fixedly connected to the top of the ring body 2 32; a pressure block 34 is fixedly connected to the outside of the shell 33; a pressure sensor 35 is fixedly connected to the outside of the ring body 1 31; a baffle 36 is slidably connected to the inside of the shell 33; an electric push rod 37 is fixedly connected to the outside of the shell 33, and the output end of the electric push rod 37 is fixedly connected to the baffle 36; a cleaning assembly 4 is provided at the top of the shell 33; the ... The mechanical component 4 includes: a rod body 41 fixedly connected to the top of the shell 33; a plate body 42 is slidably connected to the rod body 41; a spring 43 is sleeved on the outside of the rod body 41, and the two ends of the spring 43 are respectively fixedly connected to the rod body 41 and the plate body 42; a push rod 44 is arranged at the bottom of the plate body 42; a sliding component 5 is arranged on one side of the shell 33; the sliding component 5 includes: a fixed seat 51 fixedly connected to one side of the shell 33; a connecting rod 52 is slidably connected in the fixing seat 51, and one end of the connecting rod 52 is fixedly connected to the plate body 42; a connecting rope 53 is arranged at one end of the connecting rod 52; a connecting plate 54 is arranged on the top of the baffle 36, and the other end of the connecting rope 53 is fixedly connected to the connecting plate 54.

[0043] When in use, after placing the granulator body 1 at a designated position, the prepared slurry is transported to the shell 33 by a suction pump. At this time, the baffle 36 in the shell 33 blocks the material, so that the material is accumulated on the top of the baffle 36. When the material gradually increases, the weight of the material acts on the ring body 2 32 through the baffle 36 and the shell 33, so that the ring body 2 32 slides downward on the inner side of the ring body 1 31, and the pressing block 34 applies pressure to the pressure sensor 35. The total amount of material fed is monitored by the value change monitored by the pressure sensor 35. When the designated value is reached, After that, the suction pump is turned off through the PLC control box, and the electric push rod 37 is turned on, so that the output end of the electric push rod 37 pushes the baffle 36 to slide outward on the shell 33. While sliding, the shell 33 and the baffle 36 are pressed against each other to clean the residual materials on the top of the baffle 36, so as to ensure the accuracy of the subsequent feeding amount, and finally make all the materials on the baffle 36 fall into the granulator body 1, completing the single feeding, and then the electric push rod 37 is reset, so that the baffle 36 blocks the shell 33 again, and the suction pump is turned on again, and the above steps are repeated to perform accurate feeding again;

[0044] Before the electric push rod 37 is reset, the plate body 42 is pulled downward to make the plate body 42 slide downward on the outside of the rod body 41, and at the same time, the spring 43 is pulled to drive the push rod 44 to slide downward. The push rod 44 is closely attached to the inner side of the shell 33 and slides downward, so that the residual materials inside the shell 33 are cleaned into the granulator body 1 to prevent the residual materials inside the shell 33.

[0045] When the electric push rod 37 is turned on, the material falls into the granulator body 1 from the top of the baffle 36, and the baffle 36 pulls the connecting rod 52 to slide downward in the fixed seat 51 through the connecting plate 54 and the connecting rope 53. While sliding, the connecting rod 52 pulls the plate body 42 to slide downward on the rod body 41, so that the baffle 36 slides outward and the push rod 44 cleans the inside of the shell 33, thereby improving practicality.

[0046] In some embodiments, the connecting plate 54 is fixed to the baffle 36 by bolts, so that the connecting plate 54 can be fixed to or separated from the baffle 36, so that when the baffle 36 slides outward, the push rod 44 can slide downward or not slide, thereby improving practicality.

[0047] In some embodiments, a trapezoidal groove is formed on the inner side of the shell 33 , and the baffle 36 is inserted into the trapezoidal groove to prevent residual materials in the shell 33 , and the baffle 36 can provide a good shielding effect on the materials.

[0048] In some embodiments, a support assembly 6 is provided on the granulator body 1; the support assembly 6 includes: a slide rail 61 fixedly connected to the granulator body 1; a support frame 62 slidably connected to the support frame 62; a mounting seat 63 is provided at the top of the support frame 62; and a feeding pipe 64 is provided on the inner side of the mounting seat 63.

[0049] When in use, after connecting the discharge port of the suction pump to the feeding pipe 64 through a pipeline, the suction pump is turned on to allow the material to enter the shell 33 through the feeding pipe 64, and the support frame 62 can be pushed to make it slide horizontally on the slide rail 61. When loading is achieved, one end of the feeding pipe 64 is located on the inner side of the shell 33. After loading is completed, the support frame 62 is pushed outward so that the feeding pipe 64 is located on the outer side of the shell 33, which facilitates loading without affecting the normal use of the push rod 44.

[0050] In some embodiments, an auxiliary component 7 is disposed on the plate body 42 ; the auxiliary component 7 includes: a mounting rod 71 fixedly connected to one side of the plate body 42 ; and a push block 72 fixedly connected to one end of the push block 72 .

[0051] When in use, the push rod 44 slides downward, driving the plate body 42 to slide downward, and driving the push block 72 to slide downward through the mounting rod 71, so that the push block 72 pushes the support frame 62 to slide on the slide rail 61 in the direction away from the shell 33, thereby preventing the push rod 44 from contacting the feeding tube 64 when sliding downward, thereby improving the service life.

[0052] In some embodiments, the auxiliary components 7 are provided in multiple groups, so that the lateral sliding of the support frame 62 is more stable.

[0053] In some embodiments, a slope is disposed at the bottom of the push block 72 to facilitate the push block 72 to push the support frame 62 to slide.

[0054] In some embodiments, the length of the electric push rod 37 is smaller than the length of the housing 33 to prevent the baffle 36 from being separated from the housing 33.

[0055] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", "some examples", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification.

[0056] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
