Abstract
Description
Technical Field
[0001] This utility model relates to the field of polyacrylamide dilution technology, and specifically to a polyacrylamide dilution device. Background Technology
[0002] Polyacrylamide is a linear polymer that is produced by free radical polymerization of acrylamide monomers. It is usually a white powder or small granules, easily soluble in water to form a transparent colloid, and at high concentrations it is gel-like. Polyacrylamide is known as a "universal additive" and is widely used in water treatment, oil extraction, papermaking and other fields.
[0003] In existing technology, the dilution device is linked with a liquid level controller, a water inlet solenoid valve, and a dry powder conveyor to precisely control the dosage. It uses non-ferrous materials (to avoid iron ion degradation of PAM), and the stirring structure rotates at 60-100 rpm. When the liquid level reaches the middle level, the water inlet and dry powder addition are automatically started. PAM powder is added slowly in proportion (e.g., 1%-3%), with uniform stirring speed to avoid clumping or molecular chain breakage.
[0004] Existing equipment typically injects raw materials into the dilution tank via water pumps and dry powder conveyors. However, when adding water and dry powder, the contact area between water and polyacrylamide cannot be increased, resulting in uneven addition of polyacrylamide, affecting the mixing effect and forming insoluble lumps. Utility Model Content
[0005] To address the problems mentioned in the background section, this invention provides a polyacrylamide dilution device.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a polyacrylamide dilution device, comprising a dilution tank, a discharge pipe a fixedly connected to the lower side of the dilution tank, a water inlet pipe b fixedly connected to the upper side of the dilution tank, a servo motor a fixedly connected to the upper side of the dilution tank, the output shaft of the servo motor a extending into the dilution tank and fixedly connected to a stirring paddle a, and further comprising:
[0007] A heating chamber is provided inside a dilution tank. A heating pipe is fixedly connected to the heating chamber. A water inlet pipe a is fixedly connected to the inner wall of the upper side of the heating chamber. A drain pipe is fixedly connected to the inner wall of the lower side of the heating chamber.
[0008] A mixing mechanism for stirring the water in the heating chamber;
[0009] A metering container is fixedly connected to the upper side plate of a dilution tank, a fixing frame is fixedly connected to the lower side of the metering container, and a push plate is slidably connected inside the metering container;
[0010] The feeding mechanism is used to drive the pusher plate to move along the metering tank;
[0011] A storage tank is fixed to the upper side of a dilution tank. A feed pipe is fixed to the upper side of the storage tank, and a discharge pipe b is fixed to the lower side of the storage tank. The other end of the discharge pipe b is fixed to the upper side plate of a metering tank.
[0012] A crushing mechanism is used to crush polyacrylamide in a storage tank.
[0013] Preferably, the crushing mechanism includes a servo motor c and a scraper. The servo motor c is fixedly connected to the upper side of the storage tank. The output shaft of the servo motor c extends into the storage tank and is fixedly connected to a connecting rod. Several stirring blades are vertically fixed to the connecting rod. The scraper is fixedly connected to the stirring blades and is slidably connected to the inner wall of the storage tank.
[0014] Preferably, a filter screen is fixedly connected inside the storage tank, and the scraper is slidably connected to the upper side of the filter screen.
[0015] Preferably, the feeding mechanism includes a cylinder and a weighing sensor. The cylinder is fixed to the lower side of the fixed frame, the push plate is fixed to the telescopic end of the cylinder, the weighing sensor is fixed to the upper side of the push plate, a piston is slidably connected inside the metering tank, the weighing end of the weighing sensor is fixed to the piston, and a conical guide plate is fixed to the upper side of the piston.
[0016] Preferably, a solenoid valve is fixedly connected to the discharge pipe b.
[0017] Preferably, the mixing mechanism includes a servo motor b, which is fixedly connected to the upper side of the dilution tank, and the output shaft of the servo motor b extends into the heating chamber and is fixedly connected to a stirring paddle b.
[0018] Preferably, an ultrasonic level gauge is fixedly connected to the upper side plate of the dilution tank, and a temperature sensor and controller are fixedly connected to the upper side of the dilution tank.
[0019] Compared with the prior art, the beneficial effects of this utility model are:
[0020] This invention uses a servo motor (C) to drive the stirring blades and scraper to rotate and crush the agglomerated polyacrylamide in the storage tank. The polyacrylamide is then filtered through a screen to prevent agglomerated polyacrylamide from entering the dilution tank. A weighing sensor weighs the polyacrylamide on the piston and conical guide plate. A cylinder moves the piston and conical guide plate downwards, and a fixing frame limits the push plate, piston, and conical guide plate, allowing the polyacrylamide to diffuse and fall into the dilution tank through the conical guide plate. This invention solves the problem that existing devices cannot increase the contact area between water and polyacrylamide, leading to uneven polyacrylamide addition, affecting mixing efficiency, and forming insoluble clumps.
[0021] This invention heats the water in the heating chamber through a heating tube, and a servo motor b drives the stirring paddle b to rotate, thus mixing the water in the heating chamber. The hot water in the heating chamber heats the inside of the dilution tank, and a temperature sensor detects the temperature inside the dilution tank to maintain the water temperature at 30-40℃, which promotes the dechaining of polyacrylamide and prevents its degradation.

[0036] Heating chamber 5 is located inside dilution tank 1. Heating pipe 6 is fixedly connected inside heating chamber 5. Water inlet pipe a11 is fixedly connected to the inner wall of the upper side of heating chamber 5. Drain pipe 12 is fixedly connected to the inner wall of the lower side of heating chamber 5.
[0037] A mixing mechanism is used to stir the water in the heating chamber 5;
[0038] A metering tank 20 is fixedly connected to the upper side plate of the dilution tank 1. A fixing frame 21 is fixedly connected to the lower side of the metering tank 20. A push plate 222 is slidably connected inside the metering tank 20.
[0039] The feeding mechanism is used to drive the push plate 222 to move along the metering tank 20;
[0040] Storage tank 13 is fixed to the upper side of dilution tank 1. A feed pipe 15 is fixed to the upper side of storage tank 13. A discharge pipe b18 is fixed to the lower side of storage tank 13. The other end of discharge pipe b18 is fixed to the upper side plate of metering tank 20.
[0041] The crushing mechanism is used to crush the polyacrylamide in the storage tank 13.
[0042] In this embodiment, as Figures 1-2 ,as well as Figure 3 As shown, polyacrylamide is injected into the storage tank 13 through the feed pipe 15. The crushing mechanism drives the stirring blade 143 and scraper 144 to rotate and crush the agglomerated polyacrylamide. The filter screen 16 filters the crushed polyacrylamide.
[0043] Water is injected into the dilution tank 1 through the water inlet pipe a11, and the ultrasonic level gauge 7 measures the water level in the dilution tank 1 in order to accurately control the water level in the dilution tank 1.
[0044] When the control solenoid valve 19 is opened, polyacrylamide enters the metering tank 20 through the discharge pipe b18. The piston 224 seals the metering tank 20. The weighing sensor 223 weighs the polyacrylamide on the piston 224 and the conical guide plate 225. When the metered weight is reached, the control solenoid valve 19 is closed.
[0045] The cylinder 221 drives the piston 224 and the conical guide plate 225 to move downwards. The fixed frame 21 limits the push plate 222, the piston 224 and the conical guide plate 225, so that the polyacrylamide diffuses through the conical guide plate 225 and falls into the dilution tank 1.
[0046] Servo motor a3 drives stirring paddle a4 to stir and mix water and polyacrylamide. Heating tube 6 heats the water in heating chamber 5. Mixing mechanism drives stirring paddle b102 to rotate, mixing the water in heating chamber 5. The diluted polyacrylamide solution is discharged from dilution tank 1 through discharge pipe a2.
[0047] Example 2
[0048] The difference from Embodiment 1 is that this embodiment discloses the drive structure of the crushing mechanism:

[0050] A filter screen 16 is fixedly connected inside the storage tank 13, and a scraper 144 is slidably connected to the upper side of the filter screen 16.
[0051] In this embodiment, as Figure 2 As shown, the servo motor c141 drives the connecting rod 142 and the stirring blade 143 to rotate. The rotation of the stirring blade 143 drives the scraper 144 to rotate and crush the agglomerated polyacrylamide in the storage tank 13. The storage tank 13 is equipped with a filter screen 16 to filter the polyacrylamide and prevent the agglomerated polyacrylamide from entering the dilution tank 1, which would prevent the polyacrylamide from being diluted quickly.

[0055] A solenoid valve 19 is fixedly connected to the discharge pipe b18.
[0056] In this embodiment, as Figure 2 and Figure 3 As shown, the control solenoid valve 19 is opened, and polyacrylamide enters the metering tank 20 through the discharge pipe b18. The piston 224 seals the metering tank 20, and the weighing sensor 223 weighs the polyacrylamide on the piston 224 and the conical guide plate 225. When the metered weight is reached, the control solenoid valve 19 is closed.
[0057] The cylinder 221 drives the piston 224 and the conical guide plate 225 to move downwards. The fixed frame 21 limits the push plate 222, piston 224 and conical guide plate 225, so that the polyacrylamide diffuses through the conical guide plate 225 and falls into the dilution tank 1.
[0058] Example 4
[0059] The difference from Embodiment 3 is that this embodiment discloses a drive structure for the hybrid mechanism:

[0063] Working principle and usage process of this utility model:
[0064] In use, this utility model is as follows:
[0065] Polyacrylamide is injected into storage tank 13 through feed pipe 15. Servo motor c141 drives connecting rod 142 and stirring blade 143 to rotate. The rotation of stirring blade 143 drives scraper 144 to rotate and crush the agglomerated polyacrylamide in storage tank 13. Storage tank 13 is equipped with filter screen 16 to filter polyacrylamide and prevent agglomerated polyacrylamide from entering dilution tank 1, which would prevent the polyacrylamide from being diluted quickly.
[0066] Water is injected into the dilution tank 1 through the water inlet pipe a11, and the ultrasonic level gauge 7 measures the water level in the dilution tank 1 in order to accurately control the water level in the dilution tank 1.
[0067] When the control solenoid valve 19 is opened, polyacrylamide enters the metering tank 20 through the discharge pipe b18. The piston 224 seals the metering tank 20. The weighing sensor 223 weighs the polyacrylamide on the piston 224 and the conical guide plate 225. When the metered weight is reached, the control solenoid valve 19 is closed.
[0068] The cylinder 221 drives the piston 224 and the conical guide plate 225 to move downwards. The fixed frame 21 limits the push plate 222, the piston 224 and the conical guide plate 225, so that the polyacrylamide diffuses through the conical guide plate 225 and falls into the dilution tank 1.
[0069] Servo motor a3 drives stirring paddle a4 to mix water and polyacrylamide. Heating tube 6 heats the water in heating chamber 5. Servo motor b101 drives stirring paddle b102 to rotate, thus mixing the water in heating chamber 5. The hot water in heating chamber 5 heats the inside of dilution tank 1.
