Abstract

The utility model discloses an annulus adds dropwise add device for to reation kettle dropwise add material. The device comprises a material barrel and a reaction kettle, wherein a material thermometer, a hot water inlet pipe and a hot water return pipe are arranged on the reaction kettle, and a dripping pump for dripping materials through a pipeline is arranged between the material barrel and the reaction kettle. Still include the weighing device who weighs to the material bucket. The material bucket, weighing device, dropping pump, reation kettle and material thermometer are 2. The dropwise add speed is adjusted according to material thermometer, and the dropwise add volume is weighed according to the weighbridge and is confirmed, stops the pump after the dropwise add to a definite weight, and this device has cancelled the elevated tank and need not to carry out the operation of taking out the material or beating the material to the elevated tank, can prevent the danger that the elevated tank was revealed, avoids environmental pollution and personnel's injury.

Description

Ring-joint dripping device

Technical Field

The utility model relates to a liquid material dropwise add equipment technical field, especially relate to a synthetic one step ring of 2-chlorine-5-chloromethyl pyridine closes dropwise add device.

Background

The 2-chloro-5-chloromethyl pyridine synthesis of ring closure process production needs to adopt a dripping device in one step, the traditional dripping mode needs to set up an elevated tank on a reaction kettle, stores the materials needing dripping in the elevated tank, and manually adjusts a dripping valve according to the dripping speed to carry out dripping. The first work in working is to pump or pump the materials into the elevated tank, and the pressure difference formed by the height of the elevated tank is used for dropwise adding operation, so the operation process is complicated and unreliable. If the elevated tank is once revealed, a large amount of materials can be leaked out, so that environmental pollution or personal accidents can be caused, and the labor capacity of workers in the dropping process is also large.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a ring-closing dripping device with high safety and simple and convenient operation.

The utility model adopts the technical proposal that: the utility model provides a ring closes dropwise add device, includes material bucket and reation kettle, sets up material thermometer, hot water inlet tube and hot water wet return on reation kettle, sets up the dropwise add pump through pipeline dropwise add material between material bucket and reation kettle.

The utility model relates to a preferred embodiment is, still include the weighing device who weighs to the material bucket.

Further, the weighing device is a floor scale.

The utility model relates to a preferred embodiment is, material bucket, weighing device, drip pump, reation kettle and material thermometer are 2.

The utility model relates to a preferred embodiment is, reation kettle is enamel reation kettle.

In a preferred embodiment of the present invention, the dropping pump is a metering pump.

The utility model relates to a preferred embodiment is, the volume of material bucket is 200L-1000L.

The utility model relates to a preferred embodiment is, still include the PLC program controller who is used for controlling the dropwise add speed, the dropwise add volume of dropwise add pump and the dropwise add pump start or stop.

The utility model has the advantages that: the material barrel is placed on a weighing device to be weighed, the material is dripped into the reaction kettle by a dripping pump, the dripping speed is adjusted according to a material thermometer, the dripping amount is determined according to the weighing of a weighbridge, and the pump is stopped after the material is dripped to a certain weight. This device has cancelled the elevated tank and need not to carry out the operation of taking out the material or beating the material to the elevated tank, can prevent the danger that the elevated tank revealed, avoids environmental pollution and personnel to hurt.

Drawings

Fig. 1 is a schematic view of a ring-closing dripping device system according to an embodiment of the present invention.

The reference numbers in the figures denote: 1-material barrel, 2-dropping pump, 3-material thermometer, 4-reaction kettle, 5-weighbridge, 6-hot water inlet pipe and 7-hot water return pipe.

Detailed Description

In order to make the technical solutions of the present invention clearer and clearer for those skilled in the art, the present invention will be described in further detail with reference to the following embodiments and drawings, but the embodiments of the present invention are not limited thereto.

Referring to fig. 1, the ring-closing dropping device includes a material barrel 1 and a reaction kettle 4, a material thermometer 3, a hot water inlet pipe 6 and a hot water return pipe 7 are disposed on the reaction kettle 4, and a dropping pump 2 for dropping materials through a pipeline is disposed between the material barrel and the reaction kettle. The reaction kettle can be an enamel reaction kettle. The dropping pump is generally a metering pump, and other types of volumetric pumps or centrifugal pumps can also be adopted. It also comprises a weighing device 5 for weighing the material barrel, typically a floor scale. The volume of the material barrel can be 200L-1000L. The material barrel, the weighing device, the dripping pump, the reaction kettle and the material thermometer can be 2 at the same time.

The dripping speed of the dripping pump is related to the temperature of the materials, the dripping amount is related to the weighbridge, and the device also comprises a PLC (programmable logic controller) used for controlling the dripping speed and the dripping amount of the dripping pump and starting or stopping the dripping pump.

The working process is as follows: the method comprises the steps of putting a material barrel 1 on a weighbridge 5, dropwise adding materials into a reaction kettle 4 by using a dropwise adding pump 2, determining the dropwise adding speed according to a material thermometer 3, weighing and determining the dropwise adding amount according to the weighbridge 5, stopping the pump after dropwise adding to a certain weight, determining the dropwise adding speed according to the reading of the material thermometer 3 by using a PLC (programmable logic controller), weighing and determining the dropwise adding amount according to the weighbridge 5, and determining to stop the dropwise adding pump according to the dropwise adding total amount.

The above description is only a further embodiment of the present invention, but the scope of protection of the present invention is not limited thereto, and any person skilled in the art can replace or change the technical solution and the concept of the present invention within the scope of the present invention.
