Description

Technical Field

[0001] This utility model relates to the field of drug mixing technology, specifically a drug mixer for wastewater treatment. Background Technology

[0002] Wastewater discharge has severely polluted water resources and the living environment. To prevent this situation from worsening, the water treatment industry has developed a variety of large-scale water treatment equipment for use in the treatment of domestic and industrial wastewater. Many enterprises discharge wastewater containing large amounts of recalcitrant substances that cannot be effectively removed by single water treatment equipment. Therefore, it is often necessary to rationally add wastewater treatment agents based on the specific characteristics of the wastewater to ensure that the treated wastewater meets national discharge standards.

[0003] A search (application number: 202221292227.4) reveals a wastewater treatment chemical mixer, belonging to the field of wastewater treatment. It includes a base and a fixed frame. The fixed frame is welded to the upper surface of the base. A lifting plate is slidably installed inside the fixed frame. A drive motor is located at the center of the upper surface of the lifting plate. A transmission rod is connected to the power output end of the drive motor. A stirring paddle is movably inserted into the top of the transmission rod. A top cover is located at the center of the lower surface of the lifting plate. A rubber sealing gasket is installed inside the top cover. One end of the transmission rod movably passes through the top cover and the rubber sealing gasket. A liquid collection box is movably installed on the upper surface of the base, located directly below the top cover. A locking bolt is threaded to the bottom of the side wall of the transmission rod. A grate is installed at the top of the inner cavity of the liquid collection box.

[0004] In the process of realizing this utility model, the inventors found that the following problems in the prior art have not been solved: Although the device has the advantage of mixing a small amount of medicine, it needs to rely on the constant application of force to press down the pressure bar to maintain the position of its top cover during the mixing process to ensure mixing under sealed conditions, which is an unnecessary burden and the degree of humanization is not ideal. It urgently needs to be improved. Therefore, we propose a medicine mixer for sewage treatment. Utility Model Content

[0005] The purpose of this invention is to provide a chemical mixer for wastewater treatment, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a chemical mixer for sewage treatment, comprising a frame, a baffle placed at the bottom of the frame, a movable plate placed in the middle of the frame, and a box fixedly installed in the middle of the outer wall of the frame;

[0007] A pressure sensor is fixedly installed at the bottom of the enclosure and is fixedly connected to the frame. A mixing box is placed inside the enclosure, and a sealing strip is fixedly installed on the upper surface of the mixing box.

[0008] A handle is fixedly installed in the middle of the upper surface of the movable plate, and the handle moves through the top wall of the frame.

[0009] A recessed platform is provided on the front side of the upper surface of the movable plate, and a drive motor is fixedly installed in the recessed platform. A cover plate is fixedly installed on the lower surface of the movable plate, and a stirring rod is fixedly installed at the bottom of the drive shaft of the drive motor, and the stirring rod moves through the cover plate.

[0010] The movable plate has grooves on both sides, and a forward / reverse motor is fixedly installed in each groove. A screw is fixedly installed on one side of the drive shaft of the forward / reverse motor, and a limit block is placed on one side of the screw. The screw is screwed into the threaded groove on the limit block. An anti-slip pad is fixedly installed on the outside of the limit block. The forward / reverse motor, the limit block, and the anti-slip pad can be used together. During the use of the drug mixer, the movable plate can be moved down by holding the handle, so that the cover plate is pressed against the mixing box. Then, the forward / reverse motor drives the screw to rotate counterclockwise several times. The engagement of the screw and the threaded groove allows the limit block to move outward and presses the anti-slip pad against the frame. This achieves temporary positioning of the movable plate and the cover plate. Compared with the existing method, it is not necessary to constantly apply force to maintain the position of the cover plate, making the device more user-friendly.

[0011] As an optional solution to the technical solution of this application, a processor and a battery are fixedly installed inside the box. The battery is electrically connected to the drive motor and the forward and reverse motors respectively through wires. The data output terminal of the pressure sensor is connected to the data input terminal of the processor, and the signal input terminal of the processor is connected to the signal input terminal of the drive motor. It can be used in conjunction with components such as the forward and reverse motors, limit blocks, and anti-slip pads. During the use of the drug mixer, the movable plate can be moved down by holding the handle, so that the cover plate presses against the mixing box. Then, the forward and reverse motors drive the screw to rotate counterclockwise several times. The cooperation between the screw and the threaded groove can move the limit block outward and press the anti-slip pad against the frame, which can realize the temporary positioning of the movable plate and the cover plate. Compared with the existing method, it is not necessary to keep the cover plate in position by hand at all times, making the device more user-friendly.

[0012] As an optional solution to the technical solution of this application, a dustproof net is fixedly installed at the front opening of the box body, and conduits are fixedly installed on one side wall of the box body and the side of the movable plate near the forward and reverse motors. The dustproof net can block external dust and provide anti-collision protection, and the conduits can be used to run wires for connecting the wires of internal and external components.

[0013] As an optional solution to the technical solution of this application, ear plates are fixedly installed on both sides of the bottom of the frame, and positioning holes are opened on both sides of the ear plates. Positioning bolts can be passed through the positioning holes of the ear plates to make them screwed into the externally preset threaded structure for stable positioning of the frame, which meets the usage requirements.

[0014] As an optional solution to the technical solution of this application, an anti-slip sleeve is fixedly installed on the top of the handle, and triangular reinforcing ribs are fixedly installed on both sides of the connection between the handle and the movable plate. The anti-slip sleeve can increase the grip friction, and the reinforcing ribs can increase the connection rigidity to prevent tearing and breakage.

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

[0016] 1. This utility model discloses a chemical mixer for sewage treatment. By setting up a forward and reverse motor, a limiting block, and an anti-slip pad, during the use of the chemical mixer, the movable plate can be moved down by holding the handle, so that the cover plate is pressed against the mixing box. Then, the forward and reverse motor drives the screw to rotate counterclockwise several times. The cooperation between the screw and the threaded groove can move the limiting block outward and press the anti-slip pad against the frame, which can achieve temporary positioning of the movable plate and the cover plate. Compared with the existing method, it is not necessary to constantly apply force by hand to maintain the position of the cover plate, making the device more user-friendly.

[0017] 2. This utility model discloses a chemical mixer for wastewater treatment. By incorporating a pressure sensor and a processor, the pressure sensor detects the applied pressure during the downward pressure application of the cover plate. When the pressure exceeds a set threshold, indicating that the cover plate is sufficiently pressing against the sealing strip, the processor issues a command to drive the motor to run, followed by the operation of the limit plate. Conversely, after mixing is completed and the limit plate is removed, the pressure is set to the preset threshold, and the drive motor stops. This structural design avoids spillage of the chemical solution caused by mixing under conditions where the cover plate is not properly sealed, and the automatic start and stop of the drive motor eliminates the need for manual control, simplifying the mixing operation process.

Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figure 1-3 This utility model provides a technical solution: a chemical mixer for sewage treatment, including a frame 1. Ear plates 11 are fixedly installed on both sides of the bottom of the frame 1, and positioning holes are provided on both sides of the ear plates 11. Positioning bolts can pass through the positioning holes of the ear plates 11 to screw them onto a pre-set threaded structure for stable positioning of the frame 1, meeting usage requirements. A baffle 2 is placed at the bottom inside the frame 1, and a movable plate 3 is placed in the middle of the frame 1. A box 5 is fixedly installed in the middle of the outer wall of the frame 1. A pressure sensor 22 is fixedly installed at the bottom of the baffle 2 and is fixedly connected to the frame 1. A mixing box 21 is placed inside the baffle 2, and a sealing strip 23 is fixedly installed on the upper surface of the mixing box 21. A handle 4 is fixedly installed in the middle of the upper surface of the movable plate 3, and the handle 4 moves through the top wall of the frame 1. A top of the handle 4 is fixedly installed... The device has an anti-slip sleeve, and triangular reinforcing ribs are fixedly installed on both sides of the connection between the handle 4 and the movable plate 3. The anti-slip sleeve can improve the grip friction, and the reinforcing ribs can improve the connection rigidity to prevent tearing and breakage. A recessed platform 32 is opened on the front side of the upper surface of the movable plate 3, and a drive motor 33 is fixedly installed in the recessed platform 32. A cover plate 34 is fixedly installed on the lower surface of the movable plate 3. A stirring rod 31 is fixedly installed at the bottom of the drive shaft of the drive motor 33, and the stirring rod 31 moves through the cover plate 34. Grooves 6 are opened on both sides of the movable plate 3. A forward and reverse motor 61 is fixedly installed in the groove 6. A screw 62 is fixedly installed on one side of the drive shaft of the forward and reverse motor 61. A limit block 63 is placed on one side of the screw 62, and the screw 62 is screwed into the threaded groove 65 on the limit block 63. An anti-slip pad 64 is fixedly installed on the outside of the limit block 63.

[0025] In this technical solution, components such as the forward and reverse motor 61, the limiting block 63, and the anti-slip pad 64 can be used together. During the use of the drug mixer, the movable plate 3 can be moved down by holding the handle 4, so that the cover plate 34 presses against the mixing box 21. Then, the forward and reverse motor 61 drives the screw 62 to rotate counterclockwise several times. The cooperation between the screw 62 and the threaded groove 65 can move the limiting block 63 outward and press the anti-slip pad 64 against the frame 1, which can achieve temporary positioning of the movable plate 3 and the cover plate 34. Compared with the existing method, it is not necessary to constantly apply force by hand to maintain the position of the cover plate 34, making the device more user-friendly.

[0026] In some technical solutions, a processor 52 and a battery 51 are fixedly installed inside the housing 5. The battery 51 is electrically connected to the drive motor 33 and the forward and reverse motor 61 respectively through wires. The data output terminal of the pressure sensor 22 is connected to the data input terminal of the processor 52, and the signal input terminal of the processor 52 is connected to the signal input terminal of the drive motor 33. A dustproof net is fixedly installed at the front opening inside the housing 5. A conduit 53 is fixedly installed on one side wall of the housing 5 and the side of the movable plate 3 near the forward and reverse motor 61. The dustproof net can block external dust and provide anti-collision protection. The conduit 53 can be used to pass through wires for connecting the wires of internal and external components.

[0027] In this technical solution, components such as pressure sensor 22 and processor 52 can be used together. During the downward pressure of cover plate 34, pressure sensor 22 can detect the applied pressure. When the pressure is greater than the set threshold, it means that cover plate 34 is sufficiently pressing against sealing strip 23. Processor 52 issues an instruction to drive motor 33 to run, and then performs limit operation of movable plate 3. Conversely, after stirring is completed and the limit of movable plate 3 is canceled, the pressure is preset to the set threshold, and drive motor 33 stops. This structural design can avoid the spillage of medicine caused by stirring when cover plate 34 is not properly sealed. Moreover, the automatic start and stop of drive motor 33 does not require manual control, simplifying the stirring operation process.

[0028] Working principle: It should be noted that this utility model is a drug mixer for sewage treatment. All parts are general standard parts or parts known to those skilled in the art. Its structure and principle can be learned by those skilled in the art through technical manuals or conventional test methods.

[0029] When using a chemical mixer for wastewater treatment, the chemical mixer is transported to a suitable area for wastewater treatment. Then, the chemical solution and water are added to the mixing box 21 and the mixing box 21 is placed inside the enclosure 2. At this time, the cover plate 34 is lowered and the drive motor 33 is started to stir and mix the chemical solution and water for chemical pretreatment of wastewater.

[0030] By incorporating a forward / reverse motor 61, a limiting block 63, and an anti-slip pad 64, during the use of the drug mixer, the movable plate 3 can be lowered by gripping the handle 4, causing the cover plate 34 to press sufficiently against the mixing box 21. Subsequently, the forward / reverse motor 61 drives the screw 62 to rotate counterclockwise several times. The engagement of the screw 62 with the threaded groove 65 causes the limiting block 63 to move outward and presses the anti-slip pad 64 against the frame 1, achieving temporary positioning of the movable plate 3 and the cover plate 34. Compared to existing methods, it eliminates the need for constant manual force to maintain the position of the cover plate 34, making the device more user-friendly. During the downward pressure application of the cover plate 34, the pressure sensor 22 can detect the applied pressure. When the pressure exceeds the set threshold, it means that the cover plate 34 is sufficiently pressing against the sealing strip 23. The processor 52 issues a command to drive the motor 33 to run, and then performs the operation of the limit movable plate 3. Conversely, after the stirring is completed and the limit of the movable plate 3 is canceled, the pressure is set to the preset threshold, and the drive motor 33 stops. This structural design can avoid the spillage of medicine caused by stirring when the cover plate 34 is not properly sealed. Moreover, the automatic start and stop of the drive motor 33 does not require manual control, simplifying the stirring operation process.
