Description

Technical Field

[0001] This utility model relates to the technical field of acid and alkali cleaning equipment, specifically, to an acid and alkali cleaning device that can uniformly add acid and alkali solutions. Background Technology

[0002] In industrial parts cleaning and laboratory glassware processing, acid-base cleaning is a key process that removes stains by chemically reacting acid or alkali solutions with the surface of the object being cleaned, resulting in dirt, rust, or oxide layers. In these operations, the uniformity of the acid or alkali solution's coverage on the object's surface directly determines the cleaning effect. Even liquid distribution ensures a consistent reaction rate across all areas of the object, preventing localized residue or excessive corrosion.

[0003] Existing devices have some drawbacks in use. For example, most existing manual or semi-automatic acid and alkali cleaning equipment adopts a fixed-position dripping or one-way spraying structure (such as fixed nozzles or single-sided guide pipes). The liquid can only cover a local area within the cleaning frame. For example, in the fixed dripping method, the liquid tends to accumulate at the dripping point, while the amount of liquid in the edge area far from the dripping point is very small. The one-way spraying is limited by the nozzle angle and is difficult to cover the diagonal or edge corners of the cleaning frame, resulting in significant differences in the amount of liquid adhering to different areas of the object, forming cleaning blind spots. Utility Model Content

[0004] The purpose of this invention is to provide an acid and alkali cleaning device that can uniformly add acid and alkali solutions, solving the problem that most existing manual or semi-automatic acid and alkali cleaning devices use a fixed-position dripping or unidirectional spraying structure, and the liquid can only cover a local area within the cleaning frame.

[0005] This utility model provides the following technical solution: an acid and alkali cleaning device capable of uniformly adding acid and alkali solutions, comprising a cleaning frame, a turntable rotatably connected to one side of the upper end face of the cleaning frame via a bearing, a support plate fixedly connected to the upper end face of the turntable, a liquid guide cylinder fixedly connected to one side of the upper end face of the support plate, a rotating liquid cylinder rotatably connected to the bottom end of the liquid guide cylinder via a sealed bearing, a plurality of liquid outlet holes being arranged in a circular array at the bottom of the rotating liquid cylinder, a driving component for driving the rotating liquid cylinder being provided on the lower end face of the support plate, and a liquid delivery component for adding acid and alkali solutions being provided on the upper end face of the support plate.

[0006] As a preferred embodiment of the above technical solution, the driving assembly includes a driven gear fixedly sleeved on the outer wall of the rotating liquid cylinder, a servo motor fixedly installed on one side of the lower end face of the support plate, a drive shaft fixedly connected to the output end of the servo motor, a drive gear fixedly sleeved on the bottom outer wall of the drive shaft, and the drive gear meshing with the driven gear for transmission.

[0008] As a preferred embodiment of the above technical solution, an installation cavity is provided on one side of the cleaning frame, and a drive motor is fixedly installed on the bottom wall of the installation cavity. A rotating rod is fixedly connected to the output end of the drive motor, and the top end of the rotating rod is fixed to the lower end face of the turntable.

[0012] In this invention, when the drive assembly drives the rotating liquid cylinder to rotate at a set speed, the acid and alkali solutions inside the cylinder diffuse along the cylinder wall and are sprayed out through the bottom annular array of liquid outlet holes under the combined action of centrifugal force and gravity. This allows the spraying range of the rotating liquid cylinder to cover different areas of the cleaning frame, further eliminating the uniformity differences that may be caused by the fixed spraying position.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Example

[0020] like Figures 1-4 As shown, this utility model provides a technical solution: an acid and alkali cleaning device capable of uniformly adding acid and alkali solutions, including a cleaning frame 1. A turntable 11 is rotatably connected to one side of the upper end face of the cleaning frame 1 via a bearing. A support plate 12 is fixedly connected to the upper end face of the turntable 11. A liquid guide cylinder 13 is fixedly connected to one side of the upper end face of the support plate 12. A rotating liquid cylinder 14 is rotatably connected to the bottom end of the liquid guide cylinder 13 via a sealed bearing. Multiple liquid outlet holes 15 are arranged in a circular array at the bottom of the rotating liquid cylinder 14. A drive assembly 2 for driving the rotating liquid cylinder 14 is provided on the lower end face of the support plate 12. A useful... In the specific use of the liquid delivery component 3 for adding acid and alkali solutions, the addition of acid and alkali solutions is completed through the liquid delivery component 3 at the upper end of the support plate 12. The core is to safely guide the liquid into the liquid guide cylinder 13 (which eventually flows to the rotating liquid cylinder 14). The operator drives the rotating liquid cylinder 14 to rotate around the sealed bearing at the bottom of the liquid guide cylinder 13 through the drive component 2. During the rotation, the acid and alkali solutions in the liquid guide cylinder 13 are evenly sprayed into the cleaning frame 1 through the annular array of liquid outlet holes 15 at the bottom of the rotating liquid cylinder 14, thereby achieving uniform addition of acid and alkali solutions. After the addition is completed, the workpiece to be cleaned is placed in the cleaning frame 1 for cleaning.

[0021] As one implementation method in this embodiment, such as Figure 2As shown, the drive assembly 2 includes a driven gear 21 fixedly sleeved on the outer wall of the rotating liquid cylinder 14. A servo motor 22 is fixedly installed on one side of the lower end face of the support plate 12. The output end of the servo motor 22 is fixedly connected to the drive shaft 23. A drive gear 24 is fixedly sleeved on the bottom outer wall of the drive shaft 23. The drive gear 24 meshes with the driven gear 21 for transmission. In specific use, when adding acid or alkali solution to the liquid cylinder 13 through the liquid delivery assembly 3, the control switch of the servo motor 22 is turned on. The output end of the motor starts to rotate and drives the drive shaft 23 to rotate synchronously. The drive shaft 23 drives the drive gear 24 to rotate. Since the drive gear 24 and the driven gear 21 are in a meshing state, the power is transmitted to the driven gear 21 through the gear tooth surface, causing the driven gear 21 to rotate. The driven gear 21 drives the rotating liquid cylinder 14 fixedly connected to it to rotate synchronously. The rotating liquid cylinder 14 makes a circular motion around the sealed bearing at the bottom end of the liquid delivery cylinder 13.

[0022] The control system (such as a speed regulator) of the servo motor 22 can adjust the motor speed according to the cleaning requirements. When the speed is increased, the centrifugal force of the rotating liquid cylinder 14 increases, and the acid and alkali liquid is sprayed from the liquid outlet 15 in a wider range and with greater force. When the speed is reduced, the spraying range is relatively concentrated and the force is slower.

[0023] As one implementation method in this embodiment, such as Figure 1 As shown, the liquid delivery assembly 3 includes a liquid storage tank 31 fixedly installed on the upper surface of the support plate 12. A liquid pump 32 is fixedly installed on the upper surface of the liquid storage tank 31. A liquid guide pipe 33 is fixed between the liquid pump 32 and the liquid storage tank 31. A liquid delivery pipe 34 is fixedly connected to the outlet end of the liquid pump 32. A solenoid valve 35 is fixedly connected to the upper part of the liquid delivery pipe 34. A top cover 36 is fixedly connected to the outer wall of the discharge end of the liquid delivery pipe 34. The top cover 36 is fixedly installed on the upper surface of the liquid guide cylinder 13. In actual use, liquid is added to the liquid storage tank 31. Add an appropriate amount of acid or alkali solution (be careful not to exceed the maximum liquid level line), close the lid of the storage tank 31 to ensure a good seal, start the liquid pump 32, the liquid pump 32 starts working and draws acid or alkali solution from the storage tank 31 through the liquid guide pipe 33, the liquid is pressurized and enters the liquid delivery pipe 34, according to the cleaning requirements, open the solenoid valve 35, the acid or alkali solution in the liquid delivery pipe 34 enters the liquid guide cylinder 13 through the top cover 36, and finally flows into the rotating liquid cylinder 14, the total amount of acid or alkali solution delivered is precisely controlled by controlling the opening time of the solenoid valve 35.

[0024] As one implementation method in this embodiment, such as Figure 4As shown, a mounting cavity 16 is provided on one side of the cleaning frame 1. A drive motor 17 is fixedly installed on the bottom wall of the mounting cavity 16. A rotating rod 18 is fixedly connected to the output end of the drive motor 17. The top end of the rotating rod 18 is fixed to the lower end face of the turntable 11. In actual use, the drive motor 17 is started to drive the rotating rod 18 to rotate, thereby causing the rotating rod 18 to drive the turntable 11 to rotate, thereby adjusting the position of the support plate 12. This not only facilitates maintenance but also does not hinder the lifting and lowering of large workpieces.

[0025] As one implementation method in this embodiment, such as Figure 1 As shown, a stirring rod 41 is horizontally arranged inside the cleaning frame 1. Both ends of the stirring rod 41 are rotatably connected to the side wall of the cleaning frame 1. Multiple stirring blades 42 are fixed in a ring array on the outer wall of the stirring rod 41. By rotating the handle at the end of the stirring rod 41, the stirring blades are driven to further mix the liquid in the cleaning frame 1 to prevent acid and alkali solutions from accumulating in one place.

[0026] The cleaning frame 1 has a control console 19 on one side of its upper surface. The servo motor 22, drive motor 17, solenoid valve 35 and liquid pump 32 are all electrically connected to the control console 19. The target speed of the servo motor 22 is set on the control console 19 panel (according to the spraying requirements), and the working power of the liquid pump 32 is set (to control the liquid delivery speed). If automatic control is required, the single opening duration of the solenoid valve 35 can be preset (corresponding to a fixed addition amount).

[0027] Working principle: During use, add an appropriate amount of acid / alkali solution to the storage tank 31 (be careful not to exceed the maximum liquid level line), close the lid of the storage tank 31 to ensure a good seal, start the liquid pump 32, and the liquid pump 32 will start working and draw acid / alkali solution from the storage tank 31 through the liquid guide pipe 33. After being pressurized, the liquid enters the delivery pipe 34. According to the cleaning requirements, open the solenoid valve 35, and the acid / alkali solution in the delivery pipe 34 enters the liquid guide cylinder 13 through the top cover 36, and finally flows into the rotating liquid cylinder 14. Turn on the control switch of the servo motor 22, and the motor output end starts to rotate, driving the drive shaft 23 to rotate synchronously. 3 drives the drive gear 24 to rotate. Since the drive gear 24 and the driven gear 21 are in a meshing state, the power is transmitted to the driven gear 21 through the gear tooth surface, causing the driven gear 21 to rotate. The driven gear 21 drives the rotating liquid cylinder 14, which is fixedly connected to it, to rotate synchronously. The rotating liquid cylinder 14 makes a circular motion around the sealed bearing at the bottom of the liquid guide cylinder 13. The acid and alkali solutions in the liquid guide cylinder 13 are evenly sprayed into the cleaning frame 1 through the annular array of liquid outlet holes 15 at the bottom of the rotating liquid cylinder 14, thereby achieving uniform addition of acid and alkali solutions. After the addition is completed, the workpiece to be cleaned is placed in the cleaning frame 1 for cleaning.

[0028] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
