DETAILED DESCRIPTION

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] like Figure 1-Figure 2 As shown, a chemical raw material storage tank consists of a temperature-controlled main tank body 1 and a tank top cover 2 installed on the top of the temperature-controlled main tank body 1;

[0021] A loading barrel 20 is installed in the tank cavity of the temperature-controlled main tank body 1 through a support rod frame 18, a bottom discharge barrel 3 is installed at the bottom of the temperature-controlled main tank body 1, and an upper and lower feeding shaft 14 is rotatably installed at the center of the tank top cover 2 through a bearing. The top of the upper and lower feeding shaft 14 is connected to the drive assembly installed above the tank top cover 2, and the bottom end of the upper and lower feeding shaft 14 passes through the loading barrel 20 and extends into the bottom discharge barrel 3, which is the main discharge or temperature control feeding drive structure of powdered or granular chemical raw materials;

[0022] An umbrella-shaped annular wall 22 is fixedly sleeved on the top of the outer wall of the loading barrel 20, which can effectively disperse the bottom material to the surrounding area through the umbrella-shaped annular wall 22 for temperature control circulation. A loading auger 21 is installed on the loading and unloading shafts 14 in the loading barrel 20, and a unloading auger 19 is installed on the loading and unloading shafts 14 in the bottom discharge barrel 3. The auger driving directions of the loading auger 21 and the unloading auger 19 are opposite, which is convenient for separate loading and unloading processing.

[0023] like Figure 1-Figure 2 As shown, the present invention also discloses the following multiple more optimized specific structures:

[0024] The temperature control main tank body 1 is composed of a heat-conducting inner wall 16 and a heat-insulating outer wall 17. A spiral tube 15 is installed in the temperature control cavity sandwiched between the heat-conducting inner wall 16 and the heat-insulating outer wall 17. The spiral tube 15 is used to circulate the temperature control liquid medium to achieve internal temperature control;

[0025] A medium outlet pipe joint 5 and a medium inlet pipe joint 6 are installed on the tank wall of the temperature-controlled main tank body 1 , and both the medium outlet pipe joint 5 and the medium inlet pipe joint 6 are connected to the spiral tube 15 .

[0026] A feed hole is provided on the tank top cover 2, a feed pipe 8 is installed in the feed hole, and a feed cover 9 is installed on the top of the feed pipe 8 to facilitate the feeding of chemical raw materials.

[0027] A bottom valve 4 is installed at the bottom end of the bottom discharge cylinder 3.

[0028] A leg support 7 is installed on the temperature-controlled main tank body 1.

[0029] A sweeping roller 23 is fixedly mounted on the loading and unloading shaft 14 above the umbrella-shaped annular wall 22 , and the sweeping roller 23 is used to sweep the umbrella-shaped annular wall 22 .

[0030] The drive assembly consists of a motor 11 , a first straight bevel gear 12 and a second straight bevel gear 13 meshingly connected together. The motor 11 is connected to the first straight bevel gear 12 , and the second straight bevel gear 13 is fixed to the top of the loading and unloading shaft 14 .

[0031] An assembly protective cover 10 is installed on the outer cover of the drive assembly.

[0032] like Figure 1-Figure 2The chemical raw material storage tank shown in the figure facilitates unloading through a unloading auger. The driving directions of the unloading auger and the loading auger are opposite. Unloading is achieved when the motor 11 reverses. When it rotates forward, the powdered or granular chemical raw materials rise through the loading barrel 20, and then are evenly dispersed closer to the temperature-controlled main tank body through the umbrella-shaped ring wall 22, thereby achieving rapid and uniform temperature control.
