Description

Technical Field

[0001] The present application relates to the field of alum solution ratio control technology, and in particular to an alum solution ratio control device for tap water production. Background Art

[0002] Alum is a commonly used coagulant that reacts with impurities such as suspended matter and colloidal particles in water to form larger flocs. These flocs are more easily settled or removed by filtration, effectively purifying the water.

[0003] However, adding too much alum solution will not only increase the treatment cost, but may also introduce new pollutants and affect the water quality. Therefore, it is usually necessary to make a reasonable ratio of the alum solution. A reasonable ratio can ensure that the coagulant reacts fully with impurities, improve the coagulation effect, reduce the turbidity of the effluent, and thus optimize the water purification effect.

[0004] Existing alum proportioning mechanisms usually require crushing a whole piece of alum into powder, weighing the alum, and then adding the alum to the solution for proportioning, which makes the proportioning process of the alum solution too complicated and leads to low efficiency of the alum solution proportioning. Utility Model Content

[0005] In order to improve the efficiency of alum solution ratio, the present application provides a tap water production alum solution ratio control device.

[0006] The present application provides a device for controlling the ratio of alum solution in tap water production, which adopts the following technical solution:

[0008] By adopting the above technical solution, materials are fed into the crushing bin from the feed port, and the crushing mechanism crushes the whole piece of alum into powder. The powder enters the feeding bin through the first discharge port and falls on the feeding mechanism. The crushed alum is then sent into the proportioning chamber through the second discharge port by the feeding mechanism for proportioning. When a certain height is reached, the liquid level sensor sends a signal to the PLC control mechanism, and the PLC control mechanism controls the feeding mechanism to stop feeding, thereby realizing the proportioning of the alum liquid and improving the efficiency of the alum liquid proportioning.

Auxiliary gears are installed on both shredding rollers, and the two auxiliary gears are engaged with each other.

[0010] By adopting the above technical solution, one of the crushing rollers is driven to rotate by the crushing motor. Since both crushing rollers are rotatably connected in the crushing bin, and the auxiliary gears arranged on the two crushing rollers are engaged with each other, the two crushing rollers can rotate synchronously in opposite directions, squeezing the whole piece of alum into powder, which facilitates the dissolution of alum.

[0011] In a specific possible implementation manner, the second discharge port is arranged obliquely adjacent to a side wall of one side of the feeding mechanism, and is arranged obliquely downward from one side adjacent to the other side of the feeding mechanism.

A mounting groove is provided on the inclined side wall of the first discharge port, and the material stopping cylinder is installed in the mounting groove.

When the liquid level sensor sends a signal to the PLC control mechanism, the PLC control mechanism controls the cylinder to drive the material blocking plate to rise, thereby preventing the alum on the side wall of the first discharge port from entering the proportioning bin after the alum liquid proportioning content reaches a predetermined value, resulting in inaccurate proportioning content.

[0015] In a specific embodiment, it also includes a stirring mechanism, which includes a stirring motor and a stirring rod. The stirring motor is installed on the box body, one end of the stirring rod is rotatably connected to the box body and connected to the output shaft of the stirring motor, and the other end of the stirring rod extends into the proportioning bin.

[0016] By adopting the above technical solution, the stirring motor is installed on the box body, one end of the stirring rod is rotatably connected to the box body and connected to the output shaft of the stirring motor, and the stirring motor drives the stirring rod to rotate, thereby promoting the mixing degree of alum and water.

[0017] In a specific embodiment, the stirring rod is provided with a plurality of stirring blades along the length direction.

[0018] By adopting the above technical solution, a plurality of stirring blades are provided along the length direction of the stirring rod, thereby increasing the stirring range of the stirring rod and making the alum and water blend more fully.

[0019] In a specific embodiment, a plurality of stirring blades are staggered along the length direction of the stirring rod.

[0022] By adopting the above technical solution, the stirring rod is provided with a plurality of stirring blades along the circumference, which further increases the stirring range of the stirring rod and makes the alum and water blend more fully.

[0024] 1. Feed the material into the crushing bin from the feed port. The crushing mechanism crushes the whole alum into powder, which then enters the feeding bin through the first discharge port and falls onto the feeding mechanism. The crushed alum is then fed into the proportioning chamber through the second discharge port by the feeding mechanism for proportioning. When the alum reaches a certain height, the liquid level sensor sends a signal to the PLC control mechanism, which controls the feeding mechanism to stop feeding, thereby achieving the proportioning of the alum solution and improving the efficiency of the alum solution proportioning.

[0025] 2. The crushing motor drives one of the crushing rollers to rotate. Since both crushing rollers are connected to the crushing bin, and the auxiliary gears on the two crushing rollers are meshed with each other, the two crushing rollers can rotate synchronously in opposite directions, squeezing the whole alum into powder, which facilitates the dissolution of alum.

The second discharge port 6 is arranged at the side wall below one end of the feeding bin 5 along the feeding direction of the feeding mechanism 9. A liquid inlet 11a is provided at the side wall of the upper end of the proportioning bin 7, and a liquid outlet 12a is provided at the side wall of the upper end of the box body 1. The discharge side of the feeding mechanism 9 is located above the second discharge port 6. The PLC control mechanism 12 is installed on the box body 1, and the feeding mechanism 9 and the crushing mechanism 8 are both electrically connected to the PLC control mechanism 12.

[0033] like Figure 2 As shown, the crushing mechanism 8 includes a crushing motor 81 and a crushing roller 82. The crushing motor 81 is installed on the box body 1 corresponding to the crushing bin 3. Two crushing rollers 82 are provided. The two crushing rollers 82 rotate side by side and are connected in the crushing bin 3. The gap between the two crushing rollers 82 can allow powdered alum to pass through. The output shaft of the crushing motor 81 passes through the side wall of the box body 1 and is connected to one of the crushing rollers 82. Auxiliary gears 83 are installed on the two crushing rollers 82. The two auxiliary gears 83 are engaged with each other, thereby realizing synchronous reverse rotation of the two crushing rollers 82. The crushing motor 81 is electrically connected to the PLC control mechanism 12.

[0034] The crushing motor 81 drives one of the crushing rollers 82 to rotate. Since the two crushing rollers 82 are both rotatably connected to the crushing bin 3, and the auxiliary gears 83 arranged on the two crushing rollers 82 are engaged with each other, the two crushing rollers 82 can rotate synchronously in opposite directions, squeezing the whole piece of alum into powder, which facilitates the dissolution of the alum.

[0035] In an embodiment of the present application, a stirring mechanism 11 is also included. The stirring mechanism 11 includes a stirring motor 111 and a stirring rod 112. The stirring motor 111 is installed on the box body 1 corresponding to the proportioning bin 7. The stirring rod 112 is rotatably connected in the proportioning bin 7 and is fixedly connected to the output shaft of the stirring motor 111. A stirring blade 113 is provided on the stirring rod 112. There are multiple groups of stirring blades 113. The multiple groups of stirring blades 113 are arranged along the length direction of the stirring rod 112, and the multiple groups of stirring blades 113 are staggered. Each group of stirring blades 113 is provided with several stirring blades, and the several stirring blades 113 are evenly installed along the circumference of the stirring rod 112. The stirring motor 111 is electrically connected to the PLC control mechanism 12.

[0036] The stirring motor 111 is installed on the box body 1, and one end of the stirring rod 112 is rotatably connected to the box body 1 and connected to the output shaft of the stirring motor 111. The stirring motor 111 drives the stirring rod 112 to rotate, thereby promoting the mixing degree of alum and water.

[0037] It also includes a liquid level sensor 13, which is installed in the proportioning bin 7 and is electrically connected to the PLC control mechanism 12. It can detect the water level in the box 1 and send a signal to the PLC control mechanism 12.

[0038] like Figure 3 As shown, it also includes a material blocking mechanism 10, the second discharge port 6 is inclined on the side wall adjacent to the feeding mechanism 9, and is inclined downward from one side to the other side adjacent to the feeding mechanism 9, and a mounting groove 61 is provided at the lower end of the inclined side wall of the second discharge port 6, the material blocking mechanism 10 includes a material blocking cylinder 101 and a material blocking plate 102, the material blocking cylinder 101 is installed in the mounting groove 61, the material blocking plate 102 is slidably connected in the mounting groove 61, and is fixedly connected to the output shaft of the material blocking cylinder 101, and the material blocking cylinder 101 is electrically connected to the PLC control mechanism 12.

[0039] When the liquid level sensor 13 sends a signal to the PLC control mechanism 12, the PLC control mechanism 12 controls the cylinder to drive the baffle plate 102 to rise, so as to prevent the alum on the side wall of the first discharge port 4 from entering the proportioning bin 7 after the alum liquid proportioning content reaches a predetermined value, resulting in inaccurate proportioning content.

[0040] The implementation principle of the alum liquid proportioning control device for tap water production in the embodiment of the present application is as follows: a whole piece of alum is put into the crushing bin 3 from the feed port 2, and the two crushing rollers 82 are driven to rotate synchronously in opposite directions by the crushing motor 81, and the whole piece of alum is crushed into powder. The powdered alum falls on the feeding mechanism 9 through the first discharge port 4, and is fed into the second discharge port 6 by the feeding mechanism 9, and falls into the proportioning bin 7 along the inclined side wall of the second discharge port 6. The stirring rod 112 is driven by the stirring motor 111 to stir the solution, promote the mixing of alum and water, thereby improving the efficiency of the alum liquid proportioning. When the liquid level sensor 13 detects that the liquid level in the proportioning bin 7 reaches a certain height, the liquid level sensor 13 sends a signal to the PLC control mechanism 12, and the feeding mechanism 9 is closed by the PLC control mechanism 12, and the blocking cylinder 101 is controlled to drive the blocking plate 102 to move to block the alum located on the inclined side wall of the second discharge port 6, thereby accurately controlling the proportion content of the alum liquid.
