Description

Technical Field

[0001] The utility model relates to a vacuum feeding device for a V-shaped mixer. Background Art

[0002] At present, most of the powder material feeding processes for V-type mixers adopt vacuum feeding. Vacuum feeding can reduce the generation of dust during the feeding process, but the existing vacuum feeding devices for V-type mixers still have the following problems: 1. The air pressure generated by the pulse backblowing is about 3kg, and the air pressure is relatively small, which not only increases the blowing time, but also reduces the vacuum degree of the vacuum feeding device and reduces the feeding speed; 2. The number of filters used is small, that is, the filtration area is small, which reduces the feeding efficiency. Utility Model Content

[0022] Example

[0023] Reference Figures 1 to 5The present embodiment provides a vacuum feeding device for a V-type mixer 13, comprising a vacuum pump trolley 1, a storage barrel 2 is arranged on the right side of the vacuum pump trolley 1, 16 first filters 3 with a size of 60x400mm are evenly arranged inside the storage barrel 2 for the first filtration of the air, a back-blowing mechanism 4 with a pulse pressure of 4-6kg is arranged on the top of the storage barrel 2 for quickly cleaning the dust adsorbed in the first filter 3, a second filter 5 is arranged on the top of the vacuum pump trolley 1, a connecting pipe 6 is arranged between the second filter 5 and the storage barrel 2 for the second filtration of the air, a vacuum tube 7 is arranged on the storage barrel 2, a feeding tee 8 is arranged at the other end of the vacuum tube 7, a feeding hose 9 is arranged on the feeding tee 8 for feeding, and a PCB controller 10 is arranged on the top of the vacuum pump trolley 1 for controlling the entire vacuum feeding device.

[0024] The vacuum pump trolley 1 has a built-in vacuum pump (not shown in the figure) and is placed next to the V-shaped mixer 13. A storage barrel 2 is installed on the right side of the vacuum pump trolley 1 through a fixing rod. A first filter 3 is installed inside the storage barrel 2. In this embodiment, the original number of 12 filters with a size of 60x300mm is replaced with the following Figure 2 The number shown is 16, and the first filter 3 with a size of 60x400mm is used to increase the filtering area, thereby speeding up the feeding speed. The first filter 3 can be used to filter the air extracted from the V-shaped mixer 13 for the first time. A back-blowing mechanism 4 is installed on the top of the storage barrel 2. In this embodiment, the original pulse pressure of about 3kg is replaced by a pulse pressure of 4-6kg to achieve an instantaneous pressure increase, so that the dust adsorbed by the filter falls off quickly, that is, the effect of quickly cleaning the dust adsorbed in the first filter 3 is achieved, and the feeding speed is further accelerated. A second filter 5 is installed on the top of the vacuum pump trolley 1, and one end of the second filter 5 is connected to the vacuum pump inside the vacuum pump trolley 1, and the other end of the second filter 5 is installed with a connecting pipe 6, and the other end of the connecting pipe 6 is connected to the air outlet of the storage barrel 2. Then, the dust-containing air is filtered by the first filter 3 in the storage barrel 2 and then enters the second filter 5 through the connecting pipe 6, thereby realizing a second filtration of the air to discharge clean air and achieve the effect of dust-free feeding. A vacuum tube 7 is installed at the air inlet of the storage barrel 2, and the other end of the vacuum tube 7 is connected to the vacuum port of the feeding tee 8. The vacuum port of the feeding tee 8 is connected to the interior of the V-type mixer 13. The air in the V-type mixer 13 is extracted through the vacuum tube 7 to make the interior of the V-type mixer 13 in a negative pressure state, thereby realizing the effect of automatic feeding. A feeding hose 9 is installed at the feeding port of the feeding tee 8, and the other end of the feeding hose 9 is inserted into the barrel 14 for feeding. A PCB controller 10 is installed on the top of the vacuum pump trolley 1 for controlling the entire vacuum feeding device.

[0025] Furthermore, in this embodiment, a recovery bucket 11 is installed at the bottom of the storage bucket 2 to facilitate the recovery of dust dropped from the first filtration.

[0026] Furthermore, in this embodiment, a first clamp 12 is installed on the top of the storage barrel 2, and the storage barrel 2 is connected to the back-blowing mechanism 4 through the first clamp 12, so as to achieve the effect of quick disassembly between the back-blowing mechanism 4 and the storage barrel 2. When the powder raw material needs to be replaced, the back-blowing mechanism 4 can be quickly removed from the storage barrel 2 to facilitate cleaning of the storage barrel 2.

[0027] Specifically, the feed three-way pipe 8 includes a feed pipe 81, a second clamp 82, a three-way valve body 83, a clamp 84 and a third clamp 85. The top of the three-way valve body 83 is connected to the feed pipe 81 through the second clamp 82, and the bottom end of the three-way valve body 83 is provided with a clamp 84, and the three-way valve body 83 is connected to the clamp 84 through the third clamp 85.

[0028] The feed three-way pipe 8 is mainly composed of a feed pipe 81, a second clamp 82, a three-way valve body 83, a clamp 84 and a third clamp 85. The top of the feed pipe 81 near the feed port is equipped with a three-way valve body 83 through the second clamp 82, so that the feed pipe 81 and the three-way valve body 83 can be quickly disassembled to facilitate the cleaning of the feed three-way pipe 8. The clamp 84 is installed at the bottom end of the three-way valve body 83 through the third clamp 85. The clamp 84 is generally fixed in advance at the feed port of the V-type mixer 13. That is, when the feed three-way pipe 8 needs to be installed, the three-way valve body 83 can be quickly installed on the clamp 84 directly through the third clamp 85 to achieve rapid disassembly and assembly of the feed three-way pipe 8 and the V-type mixer 13, thereby improving the feeding efficiency.

[0029] Furthermore, in this embodiment, a first sealing ring 86 is installed between the feed pipe 81 and the three-way valve body 83 to improve the sealing between the feed pipe 81 and the three-way valve body 83, and a second sealing ring 87 is installed between the three-way valve body 83 and the clamp 84 to improve the sealing between the three-way valve body 83 and the clamp 84.

[0030] Furthermore, in the present embodiment, the material of the first filter 3 and the second filter 5 is 316 stainless steel, so that the first filter 3 and the second filter 5 can be sintered, which can not only achieve the effect of high-temperature sterilization, but also can be used permanently without frequent replacement, thereby reducing the cost of use.

[0031] When in use, first install the feed tee 8 to the mounting clamp 84 on the V-type mixer 13 through the third clamp 85, then insert the feed hose 9 into the barrel 14, and then control the vacuum pump trolley 1 to start the vacuum through the PCB controller 10. The air in the V-type mixer 13 enters the vacuum tube 7 through the vacuum port on the feed tee 8, so that the V-type mixer 13 is in a negative pressure state, so that the powder material in the barrel 14 enters the V-type mixer 13 through the feed hose 9 and the feed tee 8. After the air enters the storage barrel 2 through the vacuum tube 7, the 16 first filters 3 with a size of 60x400mm will filter the air entering the vacuum tube 7. The air is first filtered. During this process, the back-blowing mechanism 4 will emit a pulse pressure of 4-6kg to achieve an instantaneous pressure increase, so that the dust adsorbed by the filter falls off quickly to speed up the feeding speed. After completing the first filtration, the air will enter the second filter 5 through the connecting pipe 6, and be filtered for the second time. Finally, the clean air will be discharged to achieve dust-free feeding. After completing the feeding, the staff can quickly remove the feed tee pipe 8 through the third clamp 85, and install the blind plate 15 on the clamp 84 through the third clamp 85 to achieve the blocking of the clamp 84, so that the V-type mixer 13 can work quickly.

[0032] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
