Detailed Description
For a better understanding of the objects, structures and functions of the present utility model, the solid-dissolving feeding apparatus of the present utility model will be described in further detail with reference to the accompanying drawings. However, the present utility model is not limited to the specific embodiments, and any modifications and variations within the scope not departing from the gist of the present utility model fall within the scope of the present utility model.
As shown in fig. 1, the solid dissolution feeding equipment comprises a dissolution tank 1, a discharging system and a reverse external circulation system; the solution tank 1 is provided with a solid feed inlet 2 and a liquid feed inlet 4 at the upper part, and discharge ports are respectively arranged at the side part and the bottom part and are communicated through the reverse external circulation system; the discharging system comprises a circulating pump 7, a feeding valve F3 arranged at the upstream of the circulating pump 7, a discharging valve F4 arranged at the downstream of the circulating pump 7 and a connecting pipeline, and materials in the solution tank 1 are led into a reaction kettle 9 at the downstream from a bottom discharging hole 5; the reverse external circulation system comprises a reverse external circulation feed valve F1, a circulation pump 7, a reverse external circulation discharge valve F2 and a connecting pipeline, and materials are led into the bottom discharge port 5 from the side discharge port 6 and returned to the solution tank 1; the discharging system and the reverse external circulation system share a circulating pump 7, and the circulating pump 7 is a diaphragm pump or a centrifugal pump; after solid materials and liquid materials are put into the solution tank 1 from the solid feed inlet 2 and the liquid feed inlet 4, a reverse external circulation system is started to perform forced circulation until the materials are dissolved, and then a discharging system is started to discharge.
In the solid dissolution feeding equipment, the reverse external circulation system is arranged, so that the mixing and dissolution of solid and liquid raw materials can be realized without installing a stirring device in the dissolution tank, the dissolution tank without the stirring device is static, the dissolution tank can be conveniently installed in a first building, and the fixing device is simplified, thereby greatly saving the equipment and site cost.
In the solid dissolution feeding equipment, the external circulation system is reversely arranged, so that the disturbance of the materials from bottom to top can be realized, the dissolution of the solid materials is promoted, and the phenomenon that the solid materials enter the circulation system to block pipes or damage the circulation pump before being dissolved can be avoided. The reason is that after the solid and liquid raw materials are charged into the dissolution tank 1, the solid raw materials settle to the bottom of the tank before dissolution, and if the positive circulation is performed in the direction from the bottom discharge port 5 to the side discharge port 6, the undissolved solid raw materials may clog the pipe and damage the circulation pump 7. In contrast, the reverse circulation from the side discharge port 6 to the bottom discharge port 5 has only the upper liquid material entering the circulation system at the initial stage of the circulation, no solids, and the material rapidly realizes the dissolution along with the progress of the circulation, so that the problems of pipe blockage and pump damage do not occur.
Specifically, in the utility model, after solid and liquid raw materials are put into the solution tank 1, a reverse external circulation feed valve F1, a circulation pump 7 and a reverse external circulation discharge valve F2 are firstly opened to carry out reverse external circulation, the liquid materials on the upper layer are initially guided out from a side discharge port 6, are guided back into the solution tank 1 from a bottom discharge port 5 through the circulation pump 7, and the materials in the tank are disturbed, so that the solid materials are promoted to be dissolved in the liquid. After the reverse external circulation lasts for a certain time, sampling and detecting to confirm that the materials in the tank reach a thorough dissolving state, closing the reverse external circulation feed valve F1, the circulating pump 7 and the reverse external circulation discharge valve F2 to terminate the reverse external circulation, opening the feed valve F3, the circulating pump 7 and the discharge valve F4, and introducing the dissolved materials into the reaction kettle 9.
For accurate metering of the material feed, a flow meter 8 is preferably provided downstream of the discharge valve F4.
Furthermore, in the solid dissolution feeding equipment, the discharging system and the reverse external circulation system share one circulating pump 7, and the pump not only replaces a stirring device to realize the mixing dissolution of materials, but also plays a role of pumping materials, and the dual-purpose design of one pump is also beneficial to saving the scale and cost of the equipment.
The circulating pump 7 may be a diaphragm pump or a centrifugal pump. The diaphragm pump may be a pneumatic or electric diaphragm pump, and the centrifugal pump may be a semi-open or open impeller, but a closed impeller centrifugal pump cannot be used.
In addition, in order to enlarge the solid feed inlet 2 for feeding, or to achieve closed feeding to avoid gas emissions, it is preferable to provide a solid feed bin 3 at the solid feed inlet 2. The solid feeding bin 3 is of a known structure and has no special requirement.
Industrial applicability
As described above, the solid dissolution feeding device of the utility model does not need a stirring device, is static, is convenient to install and fix, and the reverse circulation system can completely dissolve materials and avoid bad problems such as pipe blockage or pump breakage, can realize stable and accurate feeding of solid materials, and can be widely used in reactions using solid raw materials and liquid raw materials at the same time, and specific examples include, but are not limited to, preparation of ethyl bisbenzoxazole, preparation of spirotetramat suspending agent and the like.
