Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, and in particular to a bottom-entry powder mixing device. Background Technology

[0002] In today's rapidly developing modern equipment industry, various products are emerging in an endless stream. Mixing equipment is constantly innovating to meet the mixing requirements of various types of media, and the structural types of various agitators are also constantly being innovated. Energy saving and consumption reduction are of great importance in various industries. This time, we are focusing on the mixing of large tank equipment and fine powder equipment. Solid powder is prone to clogging the outlet at the bottom. The agitator is designed from the top, with a long shaft cantilever and a thicker mixing shaft. The overall configuration is large, and with the mechanical wear and tear of the mixing equipment itself, the power consumption is high and the price is expensive.

[0003] For example, a bottom-entry powder mixing device disclosed in Chinese patent literature (publication number: CN221471585U) saves costs and reduces unnecessary mechanical wear through bottom-entry mixing. In addition, nitrogen is continuously introduced into the long pipe at the bottom of the tank to blow away the fine dust inside the tank and prevent dust from accumulating at the bottom and causing blockage.

[0004] However, when nitrogen is used to purge the material accumulated at the bottom of the tank, the continuously supplied gas needs an outlet. During the gas outlet process, the powder may be carried out of the tank along with the airflow, resulting in material loss and dust pollution. Therefore, a filter bag is installed at the end of the outlet channel to allow gas to pass through while trapping the powder inside the tank. Since the discharged powder adheres to the inside of the filter bag, it needs to be replaced regularly. Otherwise, the gas outlet will be obstructed. However, frequent shutdowns for replacement not only make the operation cumbersome but also reduce the powder mixing efficiency.

[0005] Therefore, we propose a bottom-entry powder mixing device. Utility Model Content

[0028] like Figure 1-4 As shown, this utility model provides a technical solution: a bottom-entry powder mixing device, including a bottom-entry mixing tank body 1, a filter box 2 fixedly connected to the upper surface of the bottom-entry mixing tank body 1, an exhaust pipe 3 fixedly connected to one side surface of the filter box 2, a solenoid valve 4 fixedly installed on the outer surface of the exhaust pipe 3, a filter material 5 provided on the inner wall of the filter box 2, the filter material 5 can be made of polyester fiber material, symmetrically distributed guide grooves 6 are opened on the front and rear inner walls of the filter box 2, guide sliders 7 are slidably connected to the inner wall of the guide grooves 6, and movable air jet blocks 8 are fixedly connected to the opposing surfaces of the two guide sliders 7.

[0029] A reciprocating cleaning device is provided on one side surface of the movable jet block 8, and the reciprocating cleaning device includes a drive rod 9, one end of which is fixedly connected to one side surface of the movable jet block 8.

[0030] Example 2

[0031] like Figure 1-4 As shown, this utility model provides a technical solution: the other end of the drive rod 9 penetrates and extends to the other side surface of the filter box 2, and the other end of the drive rod 9 is fixedly connected to the drive block 91.

[0032] The upper surface of the drive block 91 is provided with a groove 92, the upper surface of the movable jet block 8 is fixedly connected with an air inlet hose 93, the upper surface of the bottom-entry mixing tank body 1 is fixedly connected with a filter sleeve 94, the inner wall of the filter sleeve 94 is fixedly fitted with a screen 95, the lower part of the movable jet block 8 is provided with a linear array of air nozzles, and one end of the air inlet hose 93 is connected to an external high-pressure air pump for conveying high-pressure gas.

[0033] A connecting pipe 96 is fixedly connected to the outer surface of the filter sleeve 94. One end of the connecting pipe 96 is fixedly connected to the other side surface of the filter box 2. A rotating rod 98 is installed on the upper surface of the filter sleeve 94 through a sealed bearing. One end of the rotating rod 98 is fixedly connected to a turntable 99. The connecting pipe 96 serves to transport the pre-filtered gas into the interior of the filter box 2.

[0034] A lever 910 is fixedly connected to the upper surface of the turntable 99. The outer surface of the lever 910 is slidably inserted into the inner wall of the slot 92. A first bevel gear 911 is fixedly sleeved on the outer surface of the rotating rod 98. The other end of the rotating rod 98 passes through and extends to the lower surface of the screen 95. A rotating plate 912 is fixedly connected to the other end of the rotating rod 98. The rotation of the rotating rod 98 drives the lever 910 to rotate in a circle through the turntable 99.

[0035] The upper surface of the rotating plate 912 is provided with cleaning bristles 913. The upper ends of multiple cleaning bristles 913 are in contact with the lower surface of the screen 95. The upper surface of the filter sleeve 94 is fixedly installed with a servo motor 914. The output shaft of the servo motor 914 is fixedly installed with a rotating shaft 915 through a coupling. The rotation of the rotating plate 912 drives the cleaning bristles 913 to clean the powder adsorbed below the screen 95. The screen 95 performs preliminary interception of the powder, which improves the subsequent adsorption and interception efficiency.

[0036] A second bevel gear 97 is fixedly sleeved on the outer surface of one end of the rotating shaft 915. The tooth surface of the second bevel gear 97 meshes with the tooth surface of the first bevel gear 911. The rotation of the rotating shaft 915 drives the meshing first bevel gear 911 to rotate through the second bevel gear 97.

[0037] The reciprocating moving cleaning device intercepts and filters the powder in the exhaust gas and performs backwashing cleaning, which not only ensures stable gas discharge but also eliminates the need for frequent filter bag replacements and machine shutdowns, thus making operation convenient and improving powder mixing efficiency.

[0038] The working process of this utility model:

[0039] Step 1: Place the filter bag over the end of the exhaust pipe 3, and then connect one end of the air inlet hose 93 to the external high-pressure air pump. When the gas is discharged, it passes through the screen 95 and enters the filter sleeve 94. The screen 95 intercepts large particles of powder, while some small particles of powder enter the filter box 2 through the connecting pipe 96 with the gas and are discharged after being finely filtered by the filter material 5.

[0040] Step two: When it is necessary to clean the powder adsorbed below the filter media 5, the servo motor 914 is started. The servo motor 914 drives the second bevel gear 97 to rotate via the rotating shaft 915. The rotation of the second bevel gear 97 drives the rotating plate 912 to rotate via the rotating rod 98. The rotation of the rotating plate 912 sweeps the material adsorbed below the screen 95 off through the cleaning brush 913, thereby ensuring the smooth flow of gas.

[0041] Step 3: Simultaneously, the rotation of the rotating rod 98 drives the lever 910 to rotate via the turntable 99. The rotation of the lever 910, through the cooperation of the lever groove 92, drives the drive block 91 and the drive rod 9 to reciprocate. The reciprocating movement of the drive rod 9, through the cooperation of the guide slide groove 6 and the guide slider 7, drives the moving jet block 8 to move stably. At this time, the high-pressure air pump delivers high-pressure gas to the air inlet hose 93. After the high-pressure gas enters the moving jet block 8, it is sprayed out through multiple nozzles below it. The airflow cleans the powder adsorbed below the filter material 5. At the same time, the solenoid valve 4 opens, and the cleaned powder enters the exhaust pipe 3 with the airflow and is finally collected through the filter bag. After cleaning, the solenoid valve 4 is closed. By using the filter bag during intermittent cleaning, the frequent shutdown and replacement of the filter bag are avoided.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
