Description

Technical Field

[0001] This utility model relates to the field of ammonia metering tank technology, specifically an ammonia metering tank for the production and preparation of fine chemicals. Background Technology

[0002] With the continuous development of society and the continuous progress of science, the use of metering tanks is becoming more and more widespread. Metering tanks are generally used for the storage and weighing of chemical products. However, traditional metering tanks cannot clean the residual chemical products in the tank in time after storing chemical products. Therefore, a new type of ammonia metering tank for the production and preparation of fine chemicals is needed.

[0003] There are many types of such devices on the market today, which can basically meet people's needs. However, there are still some problems. Traditional metering tanks cannot be cleaned in time after use, so their practicality is relatively weak.

[0004] For example, Chinese patent CN214308985U discloses a novel ammonia metering tank for the production and preparation of fine chemicals, including a base, an outlet, and a tank body. The tank body is located on one side of the base, a cover plate is located on the top of the tank body, and an outlet is located at the bottom of the tank body. A cleaning mechanism is located on the other side of the top of the base, and the cleaning mechanism includes a nozzle, a water pipe, a water pump, and a water storage tank, which is located on the other side of the top of the base. This invention, by providing a cleaning mechanism on the other side of the top of the base, allows for efficient cleaning of the tank interior when ammonia water is discharged from the outlet. The water pump draws water from the water storage tank through one end of the water pipe, and then delivers it to the nozzle through the other end of the water pipe. The nozzle then pressurizes the water internally and sprays it out to clean the residual chemicals inside the tank, thereby improving the cleaning effect.

[0005] However, when used to weigh liquids, workers are prone to accidentally adding too much ammonia, leading to significant measurement errors. Utility Model Content

[0006] The purpose of this invention is to provide an ammonia metering tank for the production and preparation of fine chemicals, so as to solve the problem mentioned in the background art that workers are prone to accidentally adding too much ammonia when weighing liquids, resulting in large measurement errors.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an ammonia water metering tank for the production and preparation of fine chemicals, comprising a metering tank, a floating plate and a frame, wherein the metering tank is fixedly installed above the frame and a metering device is provided inside the metering tank;

[0008] The metering device includes a lead screw motor, a lead screw, a lead screw nut, a partition, an indicator rod, a drain pipe, a collection box, a guide pipe, and a scale plate. The lead screw motor is fixedly installed above the metering tank. The lead screw is connected to the output end of the lead screw motor. The lead screw nut is threaded to the outer surface of the lead screw. The partition is fixedly connected to one side of the lead screw nut. A groove is formed on the inner wall of the metering tank. The partition is slidably connected inside the groove. The indicator rod is fixedly connected to one side of the partition. The drain pipe is fixedly connected to one side of the partition and communicates with the inside of the metering tank. The guide pipe is fixedly connected above the collection box and threaded to the other end of the drain pipe. The collection box is fixedly connected above the frame. The lead screw motor drives the lead screw to rotate, causing the partition to rise and fall, which in turn causes the drain pipe to rise and fall. The indicator rod is used to observe whether the required level has been reached. If too much ammonia is added, the excess ammonia will be discharged into the collection box through the drain pipe and the guide pipe, preventing errors caused by manual over-addition.

[0009] Preferably, a measuring groove is fixedly connected above the measuring tank, and a sliding rod is slidably connected inside the measuring groove, extending through the top of the measuring tank. A measuring block is fixedly connected above the sliding rod, and the measuring block is slidably connected to the scale line on the outer surface of the measuring groove. A float plate is fixedly connected to the bottom of the sliding rod. The float plate is raised and lowered by the ammonia water level, which in turn raises and lowers the sliding rod, causing the measuring block to move. The amount of ammonia water can be determined by observing the position of the measuring block at the scale line of the measuring groove.

[0010] Preferably, the metering tank is equipped with a cleaning device, which includes a motor, a mounting bracket, a gear, a gear ring, a hose, a cleaning tube, and a bearing. The mounting bracket is fixedly connected to the top of the metering tank, the motor is mounted on the mounting bracket, the gear is connected to the motor output end, the gear ring meshes with the outer surface of the gear, the hose is rotatably connected to the top of the cleaning tube, the cleaning tube is fixedly connected to the inner surface of the gear ring, the bearing is mounted on the top of the metering tank, and the gear ring is mounted on the top of the bearing and rotatably connected to the top of the metering tank through the bearing. High-pressure water is injected into the cleaning tube through the hose to clean the inside of the metering tank. The motor drives the gear and gear ring to rotate, thereby driving the cleaning tube to rotate and expanding the cleaning range.

[0011] Preferably, a limiting groove is provided above the inner surface of the cleaning tube, and a rotating ring is provided at the bottom of the hose. The hose and the cleaning tube are rotatably connected through the rotating ring and the limiting groove, which has a simple structure and stable operation.

[0012] Preferably, the mounting bracket has a threaded hole on its top, and the motor and the mounting bracket are connected by bolts through the threaded hole, which facilitates the maintenance and replacement of the motor and improves the convenience of the device.

[0013] Preferably, a discharge pipe is fixedly connected to the bottom of the metering tank, and a valve is fixedly installed on the outer surface of the discharge pipe. The discharge is controlled by the valve, which provides better sealing.

[0014] Preferably, the collection box is made of transparent material, and a through hole is provided on the top of the metering tank. An inlet is fixedly connected above the through hole. The inlet is connected to the ammonia source and sealed to prevent the ammonia gas from evaporating from the ammonia water from escaping and causing harm to the staff.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This ammonia metering tank for the production and preparation of fine chemicals uses a screw motor to drive the screw to rotate, causing the baffle plate to rise and fall, which in turn causes the drain pipe to rise and fall. The indicator rod is used to observe whether the required level has been reached. If too much ammonia is added, the excess ammonia will be discharged into the collection tank through the drain pipe and the guide pipe, preventing errors caused by manual over-addition. The ammonia level causes the float plate to rise and fall, which in turn causes the slide rod to rise and fall, moving the measuring block. The amount of ammonia can be determined by observing the position of the measuring block at the scale line of the measuring tank.

[0017] 2. The ammonia metering tank used in the production and preparation of this fine chemical uses a hose to inject high-pressure water into the cleaning pipe to clean the inside of the metering tank. The motor drives the gear and gear ring to rotate, thereby rotating the cleaning pipe to expand the cleaning range. The discharge is controlled by a valve, which has better sealing performance. The sealed connection can prevent the ammonia gas volatilized from the ammonia water from escaping and causing harm to the workers. Attached Figure Description
