Embodiment 1

[0022] Such as figure 1 As shown, a reaction equipment for quantitative feeding includes a reaction kettle 101 and a feeding device 102 arranged on one side of the reaction kettle 101, and a circulation pipeline 103 is arranged inside the reactor 101, and the circulation pipeline 103 Input from one side of the reactor 101 and output from the other side, a preheating device 104 is arranged outside the reactor 101, and a preheating pipe 105 is arranged inside the preheating device 104. The preheating pipe 105 is connected to the circulation pipeline 103 through the first solenoid valve 106, the feeding device 102 is provided with a feeding port 107, and the feeding port 107 is provided with a metering pump, so The feeding device 102 is connected to the reaction kettle 101 through the feeding pipe 108, the second solenoid valve 109 is arranged on the feeding pipe 108, and the single valves arranged at intervals are arranged on the circulating pipeline 103. Directional valve 110,...

Embodiment 2

[0028] Further, in order to better realize the present invention, the present invention also discloses a quantitative feeding method of reaction equipment, comprising the following steps:

[0029] S1: Input materials into the feeding device 102 through the feeding port 107, send a driving signal to the metering pump through the controller, and measure the total feeding weight during the feeding process;

[0030] S2: The controller sends a drive signal to the second solenoid valve 109 to open the second solenoid valve 109 and start to input materials into the reactor 101. During the process of completing the input of materials, the weight sensor measures the weight of the remaining materials and sends them to the controller. When the feed weight reaches the set value, the controller sends a drive signal to the second solenoid valve 109 to close the second solenoid valve 109;

[0031] S3: When it is necessary to heat the reactor, start the preheating device 104, detect the tempe...

Abstract

The invention discloses reaction equipment with quantitative charging. The reaction equipment comprises a reaction kettle and a charging device arranged on one side of the reaction kettle, wherein a circulating pipeline is arranged in the reaction kettle and is input from one side of the reaction kettle and output from the other side of the reaction kettle; a pre-heating device is arranged outside the reaction kettle; a pre-heating pipe is arranged in the pre-heating device and is connected with the circulating pipeline through a first solenoid valve; a charging hole is formed in the charging device; a metering pump is arranged at the charging hole; the charging device is connected with the reaction kettle through a charging pipe; the charging pipe is provided with a second solenoid valve; and check valves, which are arrayed at intervals, are arranged on the circulating pipeline. According to the reaction equipment, the total amount of input materials is metered by the metering pump and the decreased amount of the materials is monitored in real time through a weight sensor, so that the total amount of the conveyed materials is controlled and quantitative charging is conveniently realized; and the reaction equipment is simple in structure and convenient to use.

Description

technical field [0001] The invention relates to a reaction device for quantitative feeding and a quantitative feeding method thereof. Background technique [0002] In the chemical production process, in order to facilitate material transportation, it is necessary to quantitatively add materials and control the reaction temperature as required. The existing feeding method is mainly to feed after closing the reaction equipment, which cannot be carried out continuously, and it is inconvenient to carry out quantitative control. Contents of the invention [0003] The purpose of the present invention is to provide a reaction device for quantitative feeding and its quantitative feeding method, which can improve the problems in the prior art. By using a metering pump to measure the total amount of input material, and monitor the amount of material reduction in real time through a weight sensor, control The total amount of material conveyed is convenient to realize quantitative fe...
