Description

Technical Field

[0001] This utility model relates to the field of alum addition technology, and more specifically, to an alum addition device for wastewater treatment. Background Technology

[0002] The main function of alum in wastewater treatment is to remove suspended solids, silt, microorganisms, and odors from the water through coagulation, while also softening the water. To facilitate operation, a device is used to add alum, such as patent application number CN201710662237.X, which describes a novel alum dosing device for wastewater treatment. This device includes a dosing machine and a storage box installed on top of the dosing machine. The storage box has a storage cavity, and the bottom of the storage cavity is connected to a downwardly extending conical cavity. The extended portion of the bottom of the conical cavity extends into the dosing machine. The dosing machine at the bottom of the conical cavity has a downwardly extending connecting hole, and the extended tail of the connecting hole is connected to a dosing trough for dosing. The bottom of the tank is connected to a dispensing port that penetrates the bottom surface of the dispensing machine. A sliding cavity extending to the left and right is provided through the connecting hole near the conical cavity. A transport and control device is installed within the sliding cavity. Guide grooves are symmetrically arranged on the inner walls of the left and right sides of the dispensing tank. Each guide groove has an embedded groove in its bottom wall. A screening plate is slidably connected between the left and right guide grooves. This invention has a simple structure, is easy to operate, and can automatically refine the process, improving dispensing efficiency and uniformity while reducing waste. In contrast, the above technical solution cannot quantitatively dispense alum, resulting in insufficient dosage and ineffective impurity removal; excessive dosage not only leads to waste but also causes excessively high residual aluminum content in the water. Utility Model Content

[0003] The main purpose of this utility model is to provide an alum addition device for wastewater treatment, which can effectively solve the problems in the background technology where alum cannot be quantitatively added, resulting in insufficient addition to effectively remove impurities; and excessive addition not only leads to waste but also causes excessive residual aluminum content in the water.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an alum feeding device for wastewater treatment, comprising a support frame, a first side plate fixedly installed on the front surface of the support frame, a storage cylinder fixedly installed in the middle of the first side plate, a second side plate fixedly installed on the front surface of the support frame on the first side plate, a material inlet being opened through the surface of the second side plate, the outlet of the storage cylinder being connected to the material inlet, and a third side plate fixedly installed on the front surface of the first side plate below the second side plate, and a drive feeding assembly being provided on the third side plate.

[0005] Preferably, mounting plates are fixedly installed on both sides of the support frame, and each of the two mounting plates has several mounting holes through it.

[0006] Preferably, a discharge port is provided through the third side plate.

[0007] Preferably, the drive feeding assembly includes a hydraulic cylinder and a metering cylinder. The hydraulic cylinder is fixedly mounted on the upper surface of the third side plate, and the metering cylinder is slidably disposed on the lower surface of the second side plate.

[0008] Preferably, an mounting cylinder is fixedly installed at the lower end of the metering cylinder, and the output end of the hydraulic cylinder is located on the circumference of the mounting cylinder.

[0009] Preferably, a baffle is fixedly installed on the circumference of the metering cylinder, and the baffle is fitted to the lower surface of the mounting cylinder.

[0010] Preferably, a positioning frame is fixedly installed between the inner walls on both sides of the mounting cylinder, a servo motor is fixedly installed on the upper surface of the positioning frame, a lead screw is installed at the output end of the servo motor, a lead screw sleeve is sleeved in the middle of the lead screw, and a retaining plate is installed on the circumference of the lead screw sleeve.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] (1) The alum inside the material cylinder will fall into the metering cylinder. At this time, the hydraulic cylinder output end is extended and retracted, which can drive the metering cylinder to move forward and move the metering cylinder to the position of the discharge port. At this time, the servo motor output end drives the lead screw to rotate, so that the lead screw sleeve moves downward in the middle of the lead screw and moves the lead screw sleeve to the position of the installation cylinder. At the same time, the baffle can be moved into the installation cylinder. The baffle can block the metering cylinder. Since the diameter of the installation cylinder is larger than the diameter of the metering cylinder, when the baffle moves into the installation cylinder, there is a gap between the baffle and the installation cylinder. At this time, the alum will fall from the gap between the baffle and the installation cylinder and fall into the wastewater. This device can automatically and quantitatively add alum, and the position of the baffle can be adjusted at will to adjust the storage amount inside the metering cylinder and adjust the quality of the discharge. It solves the problem that insufficient addition cannot effectively remove impurities; excessive addition is not only wasteful, but also leads to excessive residual aluminum content in the water.

[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0019] like Figure 1 As shown, an alum feeding device for wastewater treatment includes a support frame 1. A first side plate 2 is fixedly installed on the front surface of the support frame 1. A storage cylinder 3 is fixedly installed in the middle of the first side plate 2. A second side plate 4 is fixedly installed on the front surface of the support frame 1 on the first side plate 2. A material inlet 10 is opened through the surface of the second side plate 4. The outlet of the storage cylinder 3 is connected to the material inlet 10. A third side plate 8 is fixedly installed on the front surface of the first side plate 2 below the second side plate 4. A drive feeding assembly 5 is provided on the third side plate 8.

[0020] like Figure 1 As shown, mounting plates 6 are fixedly installed on both sides of the support frame 1, and several mounting holes 7 are opened through both mounting plates 6 to facilitate the installation of this device.

[0021] like Figure 1 As shown, a discharge port 9 is provided through the third side plate 8 to facilitate the discharge of alum into the storage cylinder 3.

[0022] like Figure 2 , 3As shown in Figure 4, the drive feeding assembly 5 includes a hydraulic cylinder 501 and a metering cylinder 503. The hydraulic cylinder 501 is fixedly installed on the upper surface of the third side plate 8, and the metering cylinder 503 is slidably disposed on the lower surface of the second side plate 4. An installation cylinder 504 is fixedly installed at the lower end of the metering cylinder 503. The output end of the hydraulic cylinder 501 is disposed on the circumference of the installation cylinder 504. A baffle 502 is fixedly installed on the circumference of the metering cylinder 503. The baffle 502 is fitted against the lower surface of the installation cylinder 504. A positioning frame 505 is fixedly installed between the inner walls of both sides. A servo motor 506 is fixedly installed on the upper surface of the positioning frame 505. A lead screw 509 is installed at the output end of the servo motor 506. A lead screw sleeve 507 is sleeved in the middle of the lead screw 509. A baffle 508 is installed on the circumference of the lead screw sleeve 507. The alum inside the material cylinder 3 will fall into the metering cylinder 503. At this time, the hydraulic cylinder 501 is extended and retracted, which drives the metering cylinder 503 to move forward, thus moving the metering cylinder 503. When the measuring cylinder 503 moves to the discharge port 9, the output of the servo motor 506 drives the lead screw 509 to rotate, causing the lead screw sleeve 509 to move downwards in the middle of the lead screw 509, moving it to the mounting cylinder 504. Simultaneously, the baffle 508 moves into the mounting cylinder 504, blocking the measuring cylinder 503. Because the diameter of the mounting cylinder 504 is larger than the diameter of the measuring cylinder 503, when the baffle 508 moves... When the alum is installed inside the cylinder 504, there is a gap between the baffle 508 and the cylinder 504. At this time, the alum will fall from the gap between the baffle 508 and the cylinder 504 into the wastewater. This device can automatically and quantitatively add alum, and the position of the baffle 508 can be adjusted at will to adjust the storage amount inside the metering cylinder 503, thereby adjusting the quality of the material feeding. This solves the problems of insufficient dosage failing to effectively remove impurities, and excessive dosage not only being wasteful but also leading to excessively high residual aluminum content in the water.

[0023] The working principle of this alum addition device for wastewater treatment:

[0024] When using this device to add alum, the alum is first stored inside the storage cylinder 3. The alum inside the storage cylinder 3 will fall into the metering cylinder 503. At this time, the output end of the hydraulic cylinder 501 extends and retracts, which drives the metering cylinder 503 to move forward, moving the metering cylinder 503 to the position of the discharge port 9. Then, the output end of the servo motor 506 drives the lead screw 509 to rotate, causing the lead screw sleeve 509 to move downward in the middle of the lead screw 509, moving the lead screw sleeve 509 to the position of the mounting cylinder 504. At the same time, the baffle 508 is moved into the mounting cylinder 504. This device can effectively block the metering cylinder 503. Because the diameter of the mounting cylinder 504 is larger than that of the metering cylinder 503, when the baffle 508 moves into the mounting cylinder 504, a gap exists between the baffle 508 and the mounting cylinder 504. At this time, alum will fall from the gap between the baffle 508 and the mounting cylinder 504 into the wastewater. This device can automatically and quantitatively add alum, and the position of the baffle 508 can be adjusted at will to adjust the storage amount inside the metering cylinder 503 and adjust the quality of the feed. This solves the problems of insufficient dosage failing to effectively remove impurities, and excessive dosage not only being wasteful but also leading to excessively high residual aluminum content in the water.

[0025] The above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
