Description

Technical Field

[0001] This utility model belongs to the field of silicone storage, and in particular relates to a silicone storage tank. Background Technology

[0002] The silicone storage device includes a tank for storing silicone liquid. The tank has an inlet at the top for introducing the silicone liquid into the tank and an outlet at the bottom for discharging the silicone liquid. The tank is usually equipped with a stirring mechanism to agitate the silicone liquid and ensure that it is discharged evenly.

[0003] Because silica gel liquid has strong adhesion and easily adheres to the tank walls, it reduces the tank capacity and affects the amount of silica gel to be stored in the next batch. To ensure that the tank capacity remains relatively constant, a scraper is usually installed inside the tank. The scraper is mounted on a mounting frame, which has a corresponding drive structure. The mounting frame drives the scraper to rotate, causing the scraper to remove the silica gel liquid adhering to the inner wall of the tank.

[0004] Currently, there are two types of drive structures for mounting frames. One type involves the simultaneous operation of the mounting frame and the stirring mechanism, where they share the same motor and a planetary gear transmission structure is used between them. While the stirring mechanism is operating, the planetary gear transmission structure powers the mounting frame, which in turn drives the scraper to remove the adhesive residue adhering to the inner wall of the tank. This method results in a scattered and non-compact transmission structure and wastes electrical energy. The other type involves separate operation of the mounting frame and the stirring mechanism, where the drive structure for the mounting frame is separate, including a dedicated motor and gear transmission structure. After the stirring mechanism has discharged the silica gel liquid, the mounting frame rotates, causing the scraper to remove the adhesive residue adhering to the inner wall of the tank. While this method saves electrical energy, it also suffers from a non-compact structure and difficulties in arranging the components within the tank. Utility Model Content

[0005] In view of this, the present invention aims to provide a silicone storage tank to ensure that the silicone in the tank is completely discharged, while simplifying the drive structure for driving the scraper and making the internal structure of the tank more compact.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows: A silicone storage tank includes a tank body with an inlet on its side wall near the top cover and an outlet at the bottom. A bracket is provided on the top of the top cover, and a pushing element is provided on the bracket. A motor is provided at the pushing end of the pushing element. A stirring shaft is provided at the center of the tank body, and a mounting frame is also provided inside the tank body. The stirring shaft is connected to the output end of the motor. The mounting frame is rotatably mounted inside the tank body in a circumferential direction. A scraper is provided on the outer side of the mounting frame and is in close contact with the inner wall of the tank body. The stirring shaft movably extends out of the mounting frame, and a docking mechanism is provided between the stirring shaft and the mounting frame.

[0007] Furthermore, the docking mechanism includes a pin, a connecting plate, and a fixing sleeve. The connecting plate is mounted on the mounting frame and has a docking hole. The stirring shaft movably extends out of the connecting plate. The fixing sleeve is mounted on the stirring shaft and is located above the connecting plate. The fixing sleeve has an installation cavity. The pin is located in the installation cavity, and its lower end extends out from the bottom of the lower cavity of the installation cavity and faces the docking hole. A spring seat is provided at the upper end of the pin, and a spring is provided between the bottom of the upper cavity of the installation cavity and the spring seat.

[0008] Furthermore, an annular groove protrudes outward from the inner wall of the tank near the top, and a supporting step is formed on the inner wall of the tank at the location where the annular groove is opened; A limiting block is provided at the top outer end of the mounting frame. The limiting block protrudes from the scraper in the radial direction of the stirring shaft. The limiting block rests on the support step and is supported by the support step.

[0009] Furthermore, the bottom of the tank is conical.

[0010] Furthermore, the tank body is provided with a mounting base plate near the bottom of the tank. The mounting base plate is an annular plate with fixing holes for tank installation.

[0011] Furthermore, the pushing element is a hydraulic cylinder.

[0012] Compared with the prior art, the silicone storage tank of this utility model has the following advantages: This utility model has a simple and compact structure. The drive structure of the scraper is as follows: a docking structure is set between the stirring shaft and the mounting frame. After the silicone is discharged from the tank, the docking structure temporarily connects the mounting frame and the stirring shaft. The stirring shaft drives the mounting frame to rotate, and the scraper on the mounting frame scrapes off the silicone liquid adhering to the inner wall of the tank, so that the silicone liquid is completely discharged. At the same time, it prevents the problem of silicone liquid adhering to the inner wall of the tank and reducing the tank capacity. Attached Figure Description

Detailed Implementation

[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] like Figure 1 As shown, a silicone storage tank includes a tank body 1. The inlet of the tank body 1 is located on its side wall near the top cover 2. The outlet of the tank body 1 is located at the bottom, and for ease of discharge, the bottom of the tank body 1 is conical 17. A mounting base plate 18 is located on the outside of the tank body 1 near the bottom. The mounting base plate 18 is annular and has mounting holes for the tank body 1, allowing bolts to be used to mount the tank body to a frame. To improve the strength of the tank body 1, annular stiffening plates are provided circumferentially on the outer wall of the tank body 1.

[0017] A bracket 5 is centrally located on the top surface of the top cover 2 of the tank body 1. A pushing element 4, preferably a hydraulic cylinder, is mounted on the bracket 5. A motor 3 is mounted on the pushing end of the pushing element 4, and the motor 3 is located outside the tank body. An agitator shaft 9 is positioned at the center inside the tank body 1, and is connected to the output end of the motor 3. A certain distance is maintained between the agitator blades of the agitator shaft 9 and the bottom of the tank body 1 to prevent interference between the agitator blades and the bottom of the mounting bracket when the agitator shaft 9 moves downwards.

[0018] The tank body 1 is also equipped with a mounting bracket 8, the structure of which is as follows: Figure 2 , Figure 3As shown, it includes two crossbars 81 and two fixed rods 82. The two crossbars 81 are collinear, and their inner ends are connected by a connecting plate 10. The two fixed rods 82 are both downward and each is installed on the outer end of one of the crossbars 81. Scrapers 6 are provided on the outer sides of the two fixed rods 82. The cross-section of the scraper 6 is a triangular structure, as shown in the figure. Figure 4 As shown, one of its pointed corners fits against the inner wall of the tank 1. A through hole 102 is provided at the center of the connecting plate 10 corresponding to the stirring shaft 9, and two docking holes 101 are symmetrically provided on both sides of the through hole 102 on the connecting plate 10.

[0019] A limiting block 83 is provided at the top outer end of the mounting bracket 8. The limiting block 83 protrudes from the scraper 6 in the radial direction of the stirring shaft 9. The preferred structure of the limiting block 83 is that the limiting block 83 and the crossbar 81 are integrally formed, that is, the crossbar 81 protrudes outward from the fixing rod 82, and this protruding part forms the limiting block 83. Correspondingly, an annular groove protrudes outward from the inner wall of the tank 1 near the top, such as... Figure 1 As shown, the annular groove is located above the tank inlet, and a supporting step 19 is formed on the inner wall of the tank at the location where the annular groove is formed. The installation structure is as follows... Figure 1 As shown, the stirring shaft 9 extends downwards through the through hole 102 of the connecting plate 10 to the lower part of the tank body 1. The limiting block 83 is supported on the supporting step 19 and in turn supports the mounting frame 8. At the same time, the scrapers 6 on both sides of the mounting frame 8 are respectively attached to the inner wall of the tank. The connecting plate 10 is movably fitted on the stirring shaft 9, so that the stirring shaft 9 can rotate relative to the mounting frame 8.

[0020] To enable temporary connection between the stirring shaft 9 and the mounting frame 8 as needed, and to allow the stirring shaft 9 to drive the mounting frame 8 to rotate, a docking mechanism 7 is provided between the stirring shaft 9 and the mounting frame 8. The docking mechanism 7 is as follows: Figure 5 As shown, the device includes two pins 11, a fixing sleeve 12, and a connecting plate 10 connecting the two crossbars 81. The fixing sleeve 12 is installed on the stirring shaft 9 and rotates synchronously with the stirring shaft 9. The fixing sleeve 12 is located above the connecting plate 10. The fixing sleeve 12 has two mounting cavities 16. The two pins 11 are disposed in the two mounting cavities 16, and the lower ends of the two pins 11 protrude from the bottom of the lower cavity of the mounting cavity 16 and face the two mating holes 101. A spring seat 14 is provided at the upper end of the pin 11, and a spring 15 is provided between the bottom of the upper cavity of the mounting cavity 16 and the spring seat 14.

[0021] When the silica gel liquid in tank 1 has been discharged and the scraper 6 is needed to scrape off the silica gel liquid adhering to its inner wall, the push rod of the push element 4 extends, driving the motor 3 and the stirring shaft 9 to move downwards. The fixing sleeve 12 on the stirring shaft 9 also moves downwards. At this time, the motor 3 is running, and the stirring shaft 9 and the fixing sleeve 12 are rotating. When the pin 11 contacts the connecting plate 10, if the position of the pin 11 and the position of the mating hole 101 are not aligned, the connecting plate 10 presses against the pin 11, the spring 15 is compressed, the pin 11 retracts, and rotates and moves downwards with the fixing sleeve 12. Once the pin 11 is rotated to the position directly opposite the docking hole 101, the spring 15 causes the pin 11 to insert into the docking hole 101. The push rod of the lowering element 4 stops extending, and the motor 3 continues to drive the stirring shaft 9 to rotate. Since the pin 11 is now inserted into the docking hole 101 of the connecting plate 10, the connecting plate 10 and the fixing sleeve 12 are limited in the circumferential direction. The pin 11 will cause the connecting plate 10 to rotate synchronously with the fixing sleeve 12, thereby causing the mounting bracket 8 to drive the scraper 6 to rotate. The scraper 6 can clean the silica gel liquid adhering to the inner wall of the tank. After the scraping operation is completed, the motor 3 stops running, the push rod of the lowering element 4 retracts, the pin 11 disengages from the docking hole, and the connecting plate 10 and the fixing sleeve 12 separate, returning to the initial state.

[0022] In this invention, a docking structure is provided between the stirring shaft and the mounting frame to achieve temporary docking between the stirring shaft and the mounting frame. The same motor 3 can be used to perform stirring and scraping operations, saving energy and making the structure more compact. At the same time, it can ensure that the silica gel liquid is completely discharged, preventing the problem of silica gel liquid adhering to the inner wall of the tank and reducing the tank capacity.

[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
