A flocculant dosing device

Abstract

This utility model discloses a flocculant dispensing device, belonging to the field of flocculant application. The device includes several forward-rotating teeth and several reverse-rotating teeth staggered inside the dispensing frame, and a drive gear rotating inside the support frame. The drive gear meshes with the forward-rotating and reverse-rotating teeth, which are located in different directions. After meshing with the forward-rotating and reverse-rotating teeth, the rotation of the drive gear causes the dispensing frame to rotate in different directions. An arc-shaped block is provided, which can change the position of the drive gear under its action, thereby interleaving it with the forward-rotating or reverse-rotating teeth to achieve the reciprocating rotation of the dispensing frame. The position of the adjusting rod can be directly changed according to the flocculant dispensing requirements, quickly limiting the rotation angle of the dispensing frame. Furthermore, the rotation angle and error can be directly determined based on the parallelism between the adjusting rod and the edge of the sewage tank, resulting in fewer adjustment steps and allowing for quick changes to the rotation angle of the dispensing frame when changing locations.

Description

Technical Field

[0001] This utility model relates to the field of flocculants, and in particular to a flocculant dispensing device. Background Technology

[0002] Flocculants are a class of chemical agents used in water treatment, wastewater treatment, industrial production and other fields. Their core function is to aggregate suspended particles and colloidal substances in water into larger flocs through coagulation and flocculation, thereby facilitating subsequent solid-liquid separation.

[0003] The reference patent title is: A flocculant dispensing device for sewage treatment (Patent Publication No.: CN119683747A). By fixing the entire device at the center of the sewage tank, the crank connecting rod composed of a turntable and a connecting rod drives the rotating cylinder to swing periodically around the main shaft. The angle of the discharge pipe is continuously adjusted by the swing, thereby changing the throwing distance of the flocculant. As the throwing distance increases, the amount of flocculant thrown increases, so that the flocculant dosage is evenly distributed in all areas of the sewage tank. This avoids the situation of excessive flocculant in the central area of ​​the sewage tank when throwing the same number of times at different distances, effectively preventing the waste of flocculant. At the same time, the base rotates, so that the flocculant is thrown outward in a circumferential shape, realizing the comprehensive throwing of flocculant inside the sewage tank.

[0004] However, the following problems exist when implementing the above technical solutions: the rotation angle of the above devices is fixed during use, and the devices need to be fixedly set in the center of the sewage tank. It is necessary to manually install them in the center of the sewage tank. The passage in the center of the sewage tank is relatively narrow, making it difficult to install the devices quickly. In addition, there are some irregular sewage tanks, which require the flocculant to be added at an angle of less than 360 degrees. The above devices control the rotation angle and direction of rotation through a motor. When changing the usage scenario, the coverage angle needs to be measured and the control value of the motor needs to be changed. The required steps are relatively numerous, and the overall angle adjustment process is relatively cumbersome and requires a high level of technical skills from the operators.

[0005] In summary, this utility model proposes a flocculant dispensing device. Utility Model Content

[0029] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0030] like Figures 1 to 6 As shown in the figure, an embodiment of the present invention provides a flocculant dispensing device, including a dispensing rack 1 and a support 2.

[0031] It should be noted that the dispensing rack 1 includes the feeding mechanism and fixing plate in the patent title: A flocculant dispensing device for sewage treatment (patent publication number: CN119683747A), which realizes the dispensing of flocculant;

[0032] The delivery rack 1 is rotatably mounted on the top of the support 2, and a rotating mechanism is provided between the delivery rack 1 and the support 2. The rotating mechanism includes:

[0033] A plurality of forward rotating teeth 3 and a plurality of reverse rotating teeth 4 are fixedly arranged inside the delivery frame 1. The plurality of forward rotating teeth 3 and the plurality of reverse rotating teeth 4 are arranged in a circular array inside the delivery frame 1, and the projected edges of the forward rotating teeth 3 and the reverse rotating teeth 4 facing the side of the delivery frame 1 coincide.

[0034] A drive gear 5 and a drive rod 6 are rotatably disposed inside the bracket 2. The drive rod 6 is slidably disposed on the surface of the drive gear 6. The drive gear 5 meshes with both the forward rotating gear 3 and the reverse rotating gear 4. The forward rotating gear 3 and the reverse rotating gear 4 are symmetrical about the drive gear 5. A drive assembly is disposed between the drive gear 5 and the delivery frame 1.

[0035] Two adjusting rods 7 are rotatably disposed inside the dispensing frame 1. A positioning component is provided between the adjusting rods 7 and the dispensing frame 1. The positioning component is slidably disposed inside the dispensing frame 1. An arc-shaped block 8 is fixedly connected to the surface of each adjusting rod 7.

[0036] In summary, the flocculant dispensing device provided by this utility model includes several forward-rotating teeth 3 and several reverse-rotating teeth 4 staggered inside the dispensing frame 1, and a drive gear 5 rotating inside the support 2. The drive gear 5 meshes with the forward-rotating teeth 3 and the reverse-rotating teeth 4, and the forward-rotating teeth 3 and the reverse-rotating teeth 4 are located in different directions of the drive gear 5. After meshing with the forward-rotating teeth 3 and the reverse-rotating teeth 4, the rotation of the drive gear 5 causes the dispensing frame 1 to rotate in different directions. An arc-shaped block 8 is provided, which can change the position of the drive gear 5 under the action of the arc-shaped block 8, thereby interleaving with the forward-rotating teeth 3 or the reverse-rotating teeth 4 to realize the reciprocating rotation of the dispensing frame 1. The position of the adjusting rod 7 can be directly changed according to the flocculant dispensing requirements to quickly limit the rotation angle of the dispensing frame 1. The rotation angle and error can be directly judged based on the parallelism between the adjusting rod 7 and the edge of the sewage tank. There are relatively fewer adjustment steps, and the rotation angle of the dispensing frame 1 can be quickly changed when changing the site.

[0037] In some specific implementations, the drive assembly includes a motor 9 fixedly mounted on the surface of the bracket 2, the motor 9 being electrically connected to an external power source, the drive rod 6 including a drive shaft and a drive rod, the drive rod being slidably connected to the inside of the drive shaft, the surface of the drive rod being slidably connected to the drive gear 5, the end of the output shaft of the motor 9 being fixedly connected to the end of the drive shaft, a drive spring 10 being fixedly connected between the drive shaft and the drive rod, and a sliding assembly for realizing pressing and sliding being provided between the drive shaft and the drive rod;

[0038] In a further embodiment, the sliding component includes an irregular groove 11 formed inside the drive shaft, and a sliding shaft 12 is fixedly connected to the surface of the drive rod. The sliding shaft 12 is adapted to the irregular groove 11. The irregular groove 11 includes multiple rectangular grooves inside, adjacent rectangular grooves are connected and arranged in a stepped manner, and the irregular groove 11 is an annular closed groove. The annular closed groove is formed by multiple staggered rectangular grooves arranged in a stepped manner, so that the depth of different positions inside the irregular groove 11 is different. Pressing the drive rod can cause the sliding shaft 12 to slide inside the irregular groove 11, and it is limited to a specific position under the influence of its depth. Pressing again causes the sliding shaft 12 to slide and reset through the irregular groove 11, which is the same as the positioning stepped groove principle and structure of the SIM card.

[0042] In a further embodiment, the sliding rod 14 has a T-shaped cross-section, and a disassembly groove 17 is provided on the surface of the base rod. The disassembly groove 17 is connected to the end of the sliding groove 15 away from the sliding spring 16, and the disassembly groove 17 is adapted to the sliding rod 14.

[0043] In some specific implementations, the positioning component includes a positioning rod 18 slidably disposed inside the delivery rack 1. The surface of the rotating rod is provided with positioning grooves 19, and the positioning rod 18 is adapted to the positioning grooves 19. A positioning cylinder 20 is fixedly connected between the positioning rod 18 and the delivery rack 1. The end of the piston rod inside the positioning cylinder 20 is fixedly connected to the positioning rod 18. A frosted layer is provided at the end of the positioning rod 18 away from the positioning cylinder 20.

[0044] In some specific implementations, each of the rotating rods is fixedly connected to a reversing cone wheel 21, and an operating cone wheel 22 is slidably connected inside the dispensing frame 1. The operating cone wheel 22 and the reversing cone wheel 21 are meshed, and a synchronization component is provided between the operating cone wheel 22 and the dispensing frame 1. Each of the reversing cone wheels 21 has a through groove on its surface, and a through rod is fixedly connected inside the dispensing frame 1. The through rod is adapted to the through groove.

The piston rod end inside the synchronization cylinder 23 is slidably connected to the operating cone wheel 22. The position of the operating cone wheel 22 can be adjusted by the synchronization cylinder 23, thereby making the surface of the operating cone wheel 22 mesh with the two reversing cone wheels 21 simultaneously. At this time, the adjusting rod 7 can rotate in opposite directions. When the operating cone wheel 22 disengages from the two reversing cone wheels 21, the position of the adjusting rod 7 on one side can be adjusted independently.

[0046] The working principle of this utility model:

[0047] The bracket 2 is fixedly installed in a suitable position in the sewage tank. If the edge of the sewage tank is symmetrical with respect to the bracket 2, the synchronous cylinder 23 is operated to cause the reversing cone wheel 21 and the operating cone wheel 22 to mesh, and the positioning cylinder 20 is controlled to cause the end of the positioning rod 18 to disengage from the side of the positioning groove 19. The adjusting rod 7 is rotated, and after the adjusting rod 7 is rotated to a suitable position, the positioning rod 18 is reset. If the edge of the sewage tank is not symmetrical with respect to the bracket 2, after the operating cone wheel 22 and the reversing cone wheel 21 disengage, the adjusting rod 7 on one side can be directly adjusted.

[0048] During use, the motor 9 is started, and the motor 9 drives the drive gear 5 to rotate. The drive gear 5 meshes with the forward rotating gear 3, which drives the dispensing frame 1 to rotate. After the drive shaft contacts the arc block 8, the drive shaft will move down under the action of the arc block 8, causing the drive gear 5 to disengage from the forward rotating gear 3 and mesh with the reverse rotating gear 4, so that the dispensing frame 1 rotates in the opposite direction.

[0049] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
