Technical Field

[0001] The utility model belongs to the technical field of weighing equipment, in particular to a weighing and feeding device for a reaction kettle. Background Art

[0002] A reactor, broadly defined as a container for physical or chemical reactions, achieves the heating, evaporation, cooling, and low-speed mixing required by the process through structural design and parameter configuration. Reactors are widely used in the petroleum, chemical, rubber, pesticide, dye, pharmaceutical, and food industries as pressure vessels for processes such as vulcanization, nitration, hydrogenation, hydrocarbonization, polymerization, and condensation.

[0003] Before adding raw materials to a reactor, they must be accurately weighed to ensure the correct ratio within the reactor. Typically, a weighing tank is placed next to the reactor to measure the weight of the raw materials and then transfer the weighed raw materials to the reactor. However, due to space limitations within the production workshop, the weighing tank can sometimes only be placed below the reactor. Therefore, an S-shaped pipe is used to connect the weighing tank and the reactor. This can cause residual raw materials to remain in the pipe during transfer, resulting in significant errors. Utility Model Content

[0004] In order to solve the problems in the above-mentioned background technology, the utility model provides a reactor weighing and feeding device. After the weighing tank weighs the raw materials, the pressure component pressurizes the weighing tank, and the vacuum component vacuums the reactor at the same time. Under the double pressure, the raw materials in the weighing tank can be quickly pumped into the reactor through the reactor feed pipe, thereby reducing the residual raw materials in the reactor feed pipe, and further reducing the error.

[0005] The utility model provides a reactor weighing and feeding device, comprising a reactor, a vacuum pumping component connected to the reactor, a weighing tank arranged on one side of the reactor, a weighing tank feeding pipe connected to the top of the weighing tank, a second valve installed on the weighing tank feeding pipe, a weighing component for weighing raw materials arranged below the weighing tank, a reactor feeding pipe connected between the weighing tank and the reactor, a third valve installed on the reactor feeding pipe, and a pressurizing component connected to the weighing tank.

[0006] Furthermore, the vacuum pump assembly includes a vacuum pump, a vacuum pump pipe is connected between the vacuum pump and the reactor, a first valve is installed on the vacuum pump pipe, and a vacuum exhaust pipe is also connected to the vacuum pump.

[0007] Furthermore, the pressurizing component includes a pressurizing tank and a pressurizing pump, a connecting pipe is connected between the pressurizing tank and the pressurizing pump, a pressurizing pipe is connected between the pressurizing pump and the weighing tank, and a fourth valve is installed on the pressurizing pipe.

[0008] Furthermore, inert gas is stored in the pressurized tank.

[0009] Furthermore, the weighing assembly includes a floor scale, a weighing tank is placed on the floor scale, a floor scale display is provided on one side of the floor scale, and the floor scale and the floor scale display are electrically connected together through a wire.

[0010] Furthermore, the four corners of the floor scale are threadedly connected with anchor bolts for adjusting the horizontality of the floor scale.

[0011] Furthermore, a fixed frame is provided at the bottom of the weighing tank, the weighing tank is placed in the fixed frame, and the fixed frame is provided on the weighing assembly.

[0012] Furthermore, pads are provided at the four corners of the fixed frame, and the pads are provided on the weighing assembly. The pads lift the weighing tank to a certain height, and the reactor feed pipe is connected to the bottom of the weighing tank.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] (1) After the weighing tank has weighed the raw materials, the pressure component pressurizes the weighing tank, and at the same time the vacuum component vacuums the reactor. Under the dual pressure, the raw materials in the weighing tank can be quickly pumped into the reactor through the reactor feed pipe, thereby reducing the residual raw materials in the reactor feed pipe and thus reducing the error.

The volume of the weighing tank 3 is smaller than that of the reactor 1, and the weighing tank 3 and the reactor 1 are placed on the same ground. A weighing tank feed pipe 30 is connected to the top of the weighing tank 3. The weighing tank feed pipe 30 is used to add raw materials into the weighing tank 3. A second valve 31 is installed on the weighing tank feed pipe 30. The second valve 31 is used to control the on and off of the weighing tank feed pipe 30; a fixed frame 32 is provided below the weighing tank 3, and the weighing tank 3 is placed in the fixed frame 32. The fixed frame 32 is used to improve the stability of the weighing tank 3; pads 33 are fixedly connected to the four corners of the bottom of the fixed frame 32, and the pads 33 can lift the weighing tank 3 to a certain height.

[0025] A weighing assembly 4 is provided below the pad 33. The weighing assembly 4 is used to weigh the raw materials in the weighing tank 3. The weighing assembly 4 includes a floor scale 40. The weighing tank 3 and the fixed frame 32 are placed on the floor scale 40. Anchor bolts 41 are threadedly connected to the four corners of the bottom of the floor scale 40. The anchor bolts 41 can adjust the levelness of the floor scale 40, so that the floor scale 40 can remain stable and level even if the floor scale 40 is placed on an uneven ground; a floor scale display screen 42 is placed on one side of the floor scale 40. The floor scale 40 and the floor scale display screen 42 are electrically connected together by a wire. The floor scale display screen 42 can display the weight of the weighed raw materials, which is intuitively displayed in front of the staff.

[0026] A reactor feed pipe 5 is connected between the weighing tank 3 and the reactor 1, one end of the reactor feed pipe 5 is connected to the top of the reactor 1, and the other end of the reactor feed pipe 5 is connected to the bottom of the weighing tank 3. Since the pad 33 raises the weighing tank 3 to a certain height, there is installation space for the reactor feed pipe 5, and the reactor feed pipe 5 is installed at the bottom of the weighing tank 3, which can pump all the raw materials in the weighing tank 3 into the reactor 1, reduce the residual raw materials in the weighing tank 3, and thus reduce the error; a third valve 50 is installed on the reactor feed pipe 5, and the third valve 50 is used to control the on and off of the reactor feed pipe 5.

Then, the second valve 31 is closed, the first valve 22, the third valve 50 and the fourth valve 64 are opened, and the vacuum pump 20 and the pressure pump 61 work simultaneously. The vacuum pump 20 extracts the air in the reactor 1 through the vacuum pipe 21 and the vacuum exhaust pipe 23, so that the reactor 1 is in a vacuum state. The pressure pump 61 injects the inert gas in the pressure tank 60 into the weighing tank 3 through the connecting pipe 62 and the pressure pipe 63, thereby increasing the pressure in the weighing tank 3.
