Description

Technical Field

[0001] The utility model relates to the technical field of vacuum mixing and pouring equipment, in particular to a mechanism for removing filler accumulation under vacuum. Background Art

[0002] Existing vacuum mixing and pouring equipment adds filler (silicon powder) to the material tank through stainless steel delivery pipes fixed at the upper and lower ends. The delivery pipe is equipped with a quick-release KF flange near the material tank end. When the filler in the pipe is blocked, it is easy to manually clear it, which can easily cause blockage. After the filler is discharged, the material tends to rise during stirring, forming lumps at the filler discharge port, requiring manual clearing of the filler discharge pipe. The existing technology has at least one of the following problems:

[0003] (1) The existing filler delivery pipeline will be blocked during production, and can only be manually unblocked by manually dismantling the KF flange. The equipment has a low degree of automation and needs to be broken into before it can be unblocked, which takes a long time to maintain.

[0004] (2) After the filler is discharged, the material tends to rise during stirring and form lumps at the filler discharge port, which increases the frequency of blockage of the filler discharge pipe. Utility Model Content

[0007] A telescopic cylinder is arranged at the inlet; the telescopic rod of the telescopic cylinder is arranged inside the vertical pipe and is connected to a scraper; the telescopic cylinder drives the scraper to reciprocate between the inlet and the filler outlet.

[0008] In the aforementioned technical solution, this proposal proposes a mechanism for removing packing accumulation under vacuum. This mechanism can upgrade manual unclogging of packing pipes to automated machinery, reducing manual operation steps and improving the level of automated production. More specifically, a telescopic cylinder and a scraper plate are used to scrape away accumulated powder from the pipe, allowing it to fall into the equipment for the next process step.

[0016] In the above technical solution, a scraper is provided inside the quick-release flange to scrape off the filler attached to the telescopic rod of the cylinder, so as to protect the clean use of the cylinder and extend its service life.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be noted that the following examples are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Similarly, the following examples are merely partial embodiments of the present invention and are not intended to be exhaustive. All other embodiments derived by persons of ordinary skill in the art without inventive effort are intended to fall within the scope of protection of the present invention.

[0023] The utility model provides a mechanism for removing packing accumulation under vacuum, which can solve at least one technical problem mentioned in the background technology.

[0024] Example 1

[0025] See also Figure 1 A mechanism for removing packing accumulation under vacuum, comprising a lower feed tee 8, the lower feed tee 8 comprising a vertical pipe and a lateral pipe, the vertical pipe comprising an inlet 81 and a packing outlet 82; the lateral pipe comprising a packing inlet 83; and

[0026] A telescopic cylinder 2 is provided at the inlet 81; the telescopic rod of the telescopic cylinder 2 is arranged inside the vertical pipe and is connected to a scraper plate 11; the telescopic cylinder 2 drives the scraper plate 11 to reciprocate between the inlet 81 and the filler outlet 82. This case proposes a mechanism for removing filler accumulation under vacuum, which can upgrade the manual unblocking of the filler pipe to mechanical automation, reduce the manual operation steps of the equipment, and improve the level of automated production of the equipment. More specifically, the telescopic cylinder is used in conjunction with the scraper plate to scrape off the powder accumulated inside the pipe and drop it into the equipment of the next process. The specific principle will be explained in the specific implementation plan and will not be repeated here.

[0027] In this embodiment, the telescopic cylinder 2 is equipped with a cylinder proximity switch 1. This proximity switch, in conjunction with an electrical solenoid valve, controls the cylinder's stroke position. Because the scraper is fixed to the end of the cylinder, it can be controlled at fixed starting and ending positions. The principle of the proximity switch is conventional and will not be further explained here.

[0028] In this embodiment, the cylinder 2 is fixedly connected to a quick-release flange 6 via a cylinder fixing flange 4; the cylinder 2 is connected to the inlet 81 via the quick-release flange 6. The quick-release connection between the cylinder and the inlet improves disassembly efficiency.

[0029] In this example, see Figure 2 A sealing gasket 7 is provided at the connection between the quick-release flange 6 and the inlet 81; a sealing ring 3 is filled between the quick-release flange 6 and the telescopic rod. The sealing gasket 7 and the sealing ring 3 meet the internal sealing requirements of the tee.

[0030] In this example, see Figure 2 A scraper 5 is arranged between the quick-release flange 6 and the telescopic rod. A scraper 5 is provided inside the quick-release flange 6 to scrape off the filler attached to the telescopic rod of the cylinder to protect the clean use of the cylinder and extend its service life.

[0031] In this embodiment, the angle between the direction G from the inlet to the filler outlet and the direction H from the filler inlet to the filler outlet is an acute angle of 40° to 50°. The above arrangement can achieve two effects: one is to facilitate manual filling, and the other is to facilitate the falling of silicon powder during feeding, avoiding accumulation at the inlet.

[0032] Specifically, see Figure 1 A structure for removing packing accumulation under vacuum, wherein the components are coordinated as follows: a cylinder proximity switch-1 cooperates with an electrical component solenoid valve to control the cylinder stroke position; since the scraper plate-11 is fixed to the end of the cylinder, the hanging plate-11 can be controlled at a fixed starting and ending position; a compact cylinder-2 is fixed to a cylinder fixing flange-4 by bolts, and the cylinder fixing flange-4 is fixed to a quick-release flange-6 by bolts, and the quick-release flange-6 is sealed and locked with a blanking tee-8 by a quick-release clamp; a sealing ring-3 is provided inside the quick-release flange-6 to achieve vacuum sealing of the entire mechanism. Seal; a scraper-5 is provided inside the quick-release flange-6 to scrape off the filler attached to the rod diameter of the compact cylinder-2, so as to protect the clean use of the cylinder and extend its service life; when the filler needs to enter from the filler inlet and exit from the filler outlet, the compact cylinder-2 drives the scraper-11 to retract to a predetermined position, and the cylinder proximity switch-1 gives a signal to allow the filler to enter from the filler inlet; when the feeding is completed, the cylinder proximity switch-1 drives the scraper-11 to extend to seal the filler discharge port; through the coordination of the actions of the above components, the function of removing the filler accumulation in the filler delivery pipeline is realized.

[0033] This new system utilizes a compact cylinder to drive the scraper plate to reciprocate up and down, thereby automatically clearing the material pipeline, simplifying the production process and improving employee work efficiency. Without breaking the vacuum equipment, it can maintain and clear the material pipeline, greatly improving equipment operating efficiency. This new system can upgrade manual clearing of the filling pipe to mechanical automation, reducing manual operation steps and improving the level of automated production equipment.

[0034] The above description is only part of the embodiments of the present invention and does not limit the scope of protection of the present invention. Any equivalent device or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
