The utility model discloses a high metering tank for the production of a trapechein, which includes a high position metering tank, a pump body and a raw material storage tank connected to the feeding port on the top of the top metering tank. The connecting pipe between the high metering tank and the pump body is provided with a stroke switch, a float is provided inside the high counting tank, and the buoy passes through the line. The distance switch is connected with the pump body. The upper side wall of the high metering tank is set with a overflow pipe. The overflow pipe is connected with the raw material storage tank. When the liquid level in the high metering tank does not reach the alert level, the buoy hits the stroke switch, the stroke switch is closed and the pump body runs normal feed; when the level of the high metering tank is reached the level of the alarm, the level reaches the alarm. When the liquid level is stopped, the normally closed contact of the stroke switch is broken, and the pump body stops running, so as to prevent excessive preparation. In order to prevent the damage caused by the damage of the travel switch, the overflow pipe is set up with a certain gradient in the high metering tank. The overflow pipe is connected to the raw material storage tank, which is convenient to enter the raw material storage tank when the material is overprepared.
【技术实现步骤摘要】
一种敌百虫生产用高位计量槽
本技术涉及物料输送领域,具体是一种敌百虫生产用高位计量槽。
技术介绍
敌百虫是一种低毒有机磷杀虫剂,国内厂家大多数采用三氯化磷、三氯乙醛、甲醇连续法合成工艺,敌百虫生产的三种原料投料时先打入高位计量槽,然后按配比通过转子流量计控制配比投料,计量槽备料时需精心控制,稍有不慎就会出现备料过量,溢出跑料现象,造成环境污染,严重时会造成人身伤亡事故。
技术实现思路
本技术的目的是提供一种敌百虫生产用高位计量槽。本技术的目的是这样实现的:一种敌百虫生产用高位计量槽,包括高位计量槽、泵体和通过泵体与高位计量槽顶部的加料口连接的原料储罐,所述高位计量槽和泵体之间的连接管道上设有行程开关,高位计量槽内部设有浮筒,浮筒通过行程开关与泵体连接,高位计量槽侧壁上部设置有溢流管,溢流管通过管道与原料储罐相连。所述高位计量槽底部设有排净口,所述排净口通过阀门与原料储罐连接。所述高位计量槽上设有用于排出原料的出料口。所述溢流管坡度不小于10%。所述高位计量槽为立式,底部为平底或圆形或锥形。本技术的有益效果是:本技术结构简单,制作成本低,操作简单方便,当高位计量槽内液位未达到警戒液位时,浮筒撞击行程开关,行程开关常闭触点闭合,泵体运转正常进料;当高位计量槽内液位达到警戒液位时,行程开关常闭触点断开,泵体停止运转,可防止出现备料过量。为防止行程开关损坏导致出现溢出跑料,高位计量槽设置具有一定坡度的溢流管,溢流管连接至原料储罐,便于备料过量时通畅进入原料储罐。附图说明图1为本技术实施例1的结构示意图;图中:高位计量槽1,浮筒2,泵体3,原料储罐4,溢流管5,行行程开 ...
