Abstract
The utility model discloses a reaction kettle bottom discharging device in the field of chemical production equipment and aims to solve the problems that material accumulation and material clogging are easy to appear at the bottom of a reaction kettle after solid liquid reaction is finished in the prior art. The reaction kettle bottom discharging device comprises a discharging pipe connected to the bottom of the reaction kettle, a discharging valve is arranged on the discharging pipe, the discharging pipe is connected with a breather pipe in a bypass mode, the breather pipe is connected to a pipe section of the discharging pipe between the reaction kettle and the discharging valve, and a breather valve is arranged on the breather pipe. When the reaction kettle bottom discharging device works, compressed air, nitrogen or other gas which does not affect normal reaction are blown into a position wherein the breather valve is located, the reaction kettle bottom discharging device can effectively enable materials at the bottom of the reaction kettle to be in a billowing state in order to avoid agglomeration, so that difficulty of discharging is reduced. The gas can be continuously supplied in a reaction process, can be supplied at intervals in a pulse state, and can also be supplied in an impact airflow mode after the reaction is finished. The reaction kettle bottom discharging device is not only simple in structure, convenient to operate, and high in operation reliability.
Description
Technical field
The utility model relates to the solid-liquid reaction device in a kind of chemical production equipment field, particularly a kind of bottom discharge device of reactor.
Background technology
The broad understanding of reactor namely has the rustless steel container of physics or chemical reaction, by structural design and the parameter configuration to container, realize the function that is mixed of heating, evaporation, cooling and the low high speed of technological requirement, a kind of combined reaction container, according to the design of reaction condition to reactor structure function and configuration annex.All can finish pre-set reactions steps with higher automaticity, the important parameters such as the temperature in the course of reaction, pressure, mechanics control, reactant/product concentration are carried out strict regulation and control from the charging-reaction-discharging of beginning.Now be widely used in oil, chemical industry, rubber, agricultural chemicals, dyestuff, medicine, food, be used for finishing the technical process such as sulfuration, nitrated, hydrogenation, hydrocarbonylation, polymerization, condensation.
In the prior art, when carrying out solid-liquid reaction, agitating device is set in reactor usually, this agitating device can be blade, helical blade, after reaction is finished, the discharge nozzle discharging that material connects at the bottom of the still, on this discharge nozzle discharge valve is installed, open discharge valve and can realize discharging, but because buildup also can be caused, therefore near the dead angle for stirring at the bottom of the still of reactor in the discharge nozzle, discharge valve is installed near the reactor bottom is a kind of common way as far as possible, can reduce still prodelta clay material as far as possible.But, at the bottom of the still still buildup can appear, and after often occurring reacting end, the buildup at the bottom of the still can cause the discharging hard problem.
The utility model content
The purpose of this utility model provides a kind of reactor bottom drawing mechanism, makes it when carrying out solid-liquid reaction, can because still prodelta clay material affects discharging, not improve the functional reliability of reactor.
The purpose of this utility model is achieved in that a kind of reactor bottom drawing mechanism, the discharge nozzle that comprises the reactor bottom of connection, discharge nozzle is provided with discharge valve, bypass is connected with breather pipe on the described discharge nozzle, on the discharge nozzle pipeline section between described breather pipe coupled reaction still and the discharge valve, be provided with breather valve on the breather pipe.
In the utility model when work, pass into compressed air, nitrogen or other do not affect the gas of normal reaction from breather valve, can effectively make the material of reactor inner bottom part be in the state of seething, and avoids caking, thereby alleviate the difficulty of discharging.The infeed of gas can feed in course of reaction continuously, also can be pulse attitude certain interval of time and feed, and can also the mode with impact air-flow feed after reaction finishes.
As further improvement of the utility model, described breather pipe is inclined upwardly from breather valve and is connected on the discharge nozzle.The impact air-flow tiltable enters in the discharge nozzle, and is strong to the percussion of buildup, can further avoid buildup to stop up discharge nozzle.
As further improvement of the utility model, the flow area of described breather pipe is (1:20)～(1:2) with the ratio of the flow area of discharge nozzle.In this ratio range, air-flow has enough impulsive forces, simultaneously, has guaranteed that also breather pipe has enough little size, to reduce manufacturing cost.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein, 1 discharge nozzle; 2 discharge valves; 3 breather pipes; 4 breather valves.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, comprise the discharge nozzle 1 of the reactor bottom of connection, discharge nozzle 1 is provided with discharge valve 2, and bypass is connected with breather pipe 3 on the discharge nozzle 1, on discharge nozzle 1 pipeline section between breather pipe 3 coupled reaction stills and the discharge valve 2, be provided with breather valve 4 on the breather pipe 3.Breather pipe 3 is inclined upwardly from breather valve 4 and is connected on the discharge nozzle 1.The flow area of breather pipe 3 is (1:20)～(1:2) with the ratio of the flow area of discharge nozzle 1.
The utility model is not limited to above-described embodiment; on the basis of the disclosed technical scheme of the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in protection domain of the present utility model.
