Description

Chemical container cleaning device

technical field

The invention belongs to the technical field of special equipment for cleaning barrel-shaped chemical containers, and specifically discloses a chemical container cleaning device.

Background technique

Storage tanks are used to store refined chemical substances such as acids, alkalis, alcohols, gases, and liquids. Storage tanks are widely used in the chemical industry. According to different materials, there are generally: polyethylene storage tanks, polypropylene storage tanks, glass fiber reinforced plastic storage tanks, ceramic storage tanks, rubber storage tanks, stainless steel storage tanks, etc. The most widely used storage tanks in my country are vertical storage tanks, and some vertical storage tanks are installed outdoors. With the accumulation of use time, outdoor pollutants such as dust and dirt continue to accumulate on the outer wall of the storage tank. Corrosion of the outer wall of the tank, which in turn damages the tank, is one of the important factors that shorten the service life of the tank.

Vertical storage tanks are usually large in size, so it is difficult to clean the vertical storage tanks. At present, the cleaning of vertical storage tanks is usually carried out by workers, which is not only inefficient, but also because only water is used for flushing, some firmly attached dirt is difficult to wash off, resulting in incomplete cleaning.

Contents of the invention

The invention discloses a chemical container cleaning device, which aims to solve the problems of low efficiency and incomplete cleaning of vertical storage tanks by workers using water flow in the prior art.

The basic solution of the present invention is: a chemical container cleaning device, comprising a water tank with an open upper end, and the water tank is provided with a circulation part, a cleaning part, an air stem and a driving mechanism;

The circulation part includes: a cavity provided in the side wall of the water tank, a through hole provided on the inner side wall of the water tank and communicated with the cavity; the through holes are evenly distributed on the inner side wall of the water tank;

The drive mechanism includes: a power device that provides linear motion, a transmission frame that is fixedly connected to the output end of the power device, a first push rod is fixedly connected to the upper end of the transmission frame, and a first push plate is fixedly connected to the lower end of the push rod, The lower end of the drive frame is fixedly connected with a second push rod that passes through the bottom surface of the water tank and extends into the water tank.

The air stem includes a cylinder fixed on the side wall of the water tank, the upper end of the cylinder is higher than the upper edge of the water tank, the cylinder is higher than the upper edge of the water tank and has an air blowing port on the side wall facing the water tank, the piston of the cylinder The rod is fixedly connected with the drive frame;

The cleaning part includes: a cleaning ring sleeved on the outer wall of the container, the cleaning ring is rotatably connected to the water tank, and is horizontally arranged and rotatably connected to the driving gear on the inner wall of the cleaning box. The center of the driving gear has a threaded through hole, and the screw thread A lead screw is connected to the internal thread of the through hole, and the lead screw is fixedly connected with the first push rod. The outer wall of the cleaning ring is provided with teeth, and the driving gear meshes with the cleaning ring.

Technical principle of the present invention and beneficial effect are:

1. Since the device is provided with a cleaning ring, when the container is placed between the second pressing plate and the first pressing plate, the first pressing plate and the second pressing plate will move with the movement of the first push rod and the second pushing rod, and then The container is moved, and the screw rod is driven to move during the movement of the first push rod. Since the screw rod is threadedly connected with the driving gear, the screw drives the driving gear to rotate, and the driving gear drives the cleaning ring to rotate, so that the cleaning ring cleans the outer wall of the container. For cleaning, compared with the prior art that only uses water to wash, this device cleans through the direct contact between the cleaning ring and the container, which can more effectively remove the dirt attached to the outer wall of the container.

2. Since the device is equipped with a circulation part, the water in the water tank will enter the through hole and the blind hole. When the second pressure plate moves up and down, pressure will be formed on the water in the water tank, making the water flow upward along the blind hole, and then The water is sprayed out from the through hole to wash the surface of the container, and cooperate with the cleaning ring to clean the container, so that the cleaning effect is more thorough. At the same time, when the second pressure plate is moving, the water squeezed above the second pressure plate enters the blind hole along the through hole, and flows back to the water tank below the second pressure plate along the blind hole. The water above the second pressure plate flows into the through hole and the blind hole to achieve a sealing effect on the blind hole and the through hole, so that the air will not be sucked into the water tank under the second pressure plate when the second pressure plate is moving, so as to realize the water retention recycle.

3. Since the device is equipped with a wind stem, when the power device drives the transmission frame to reciprocate up and down, it drives the piston rod of the cylinder to reciprocate up and down, so that the gas in the cylinder is blown from the air outlet to the outer wall of the tank in the water tank, realizing Air-dry the outer wall of the container.

Further, the cavity surrounds the entire water tank, the cavity is annular, and the through holes are evenly distributed on the inner wall of the water tank in the circumferential direction. The pressed water can be shot into the container from all sides, so that there is no dead angle for water flushing.

Further, the upper end of the sink is fixedly connected with an annular cleaning ring positioning platform, the driving gear is rotatably connected to the upper end surface of the cleaning ring positioning platform, and the lead screw passes through the cleaning ring positioning platform and does not contact the cleaning ring positioning platform. The cleaning ring is rotatably connected with the cleaning ring positioning platform, and the cleaning ring positioning platform is provided with an opening for the container to pass through. The cleaning ring and the driving gear are positioned on the cleaning ring positioning platform without unnecessary displacement, thereby making the device work more stably.

Further, the transmission frame includes a vertical bar, a rotating bar that is rotatably connected with the vertical bar and arranged horizontally, and a first cross bar that is fixedly connected with the lower end of the vertical bar, the first push rod is fixedly connected with the rotating bar, and the first push rod is fixedly connected with the rotating bar. The two push rods are fixedly connected with the first cross bar, the piston rod of the cylinder is fixedly connected with the second cross bar, the second cross bar is fixedly connected with the vertical bar, and the upper end of the vertical bar is fixedly connected with the power device. By setting the rotating rod, the first pressing plate can be rotated, thereby making it more convenient for the container to be placed in the device, and it only needs to be placed directly from above.

Further, a plane thrust bearing is provided between the cleaning ring, the drive gear and the cleaning ring positioning platform. By arranging the plane thrust bearing, the frictional force between the cleaning ring, the drive gear and the cleaning ring positioning platform is reduced, thereby reducing the loss of kinetic energy and making the device work more efficiently.

Further, bristles are fixedly connected to the inner wall of the cleaning ring. By arranging the bristles, the cleaning ring drives the bristles to scrub the outer wall of the container during the rotation process, and the dirt attached to the outer wall of the container is brushed off, so that the cleaning is more thorough.
