Description

Technical Field

[0001] The utility model relates to the field of water production equipment, in particular to a pipeline mixer used for water production. Background Art

[0002] During the water production process, water needs to be transported to a sedimentation tank, and then alum is added for precipitation. The existing method of adding alum is usually to add it to the water inlet of the sedimentation tank through a ring pipe surface, and to stir and mix it by a motor. In the actual production process, it was found that there are at least the following problems with this method of adding: First, the distribution of alum addition is uneven, and the uneven amount of alum leads to different reaction effects in different places, which affects the precipitation effect and water quality of the water and increases the burden on the filter. Second, a motor needs to be used to mechanically stir the water in the water inlet tank, and the stirring effect is not obvious, and the motor needs to run all day, which consumes a lot of energy and greatly increases the production cost. Utility Model Content

[0003] In view of this, the utility model provides a pipeline mixer for water production, which can evenly input liquid medicine and can stir and mix water and liquid medicine by relying on water flow power.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] A pipeline mixer for water production, comprising a water inlet pipe, a mixing pipe and a water outlet pipe connected in sequence, and also comprising: a guide plate and a stirring mechanism, and a dosing mechanism, which are sequentially arranged in the mixing pipe along the direction of water flow, wherein the stirring mechanism comprises a mounting seat arranged on the inner wall of the mixing pipe, a rotating shaft rotatably arranged on the mounting seat and perpendicular to the direction of water flow, and a plurality of blades arranged on the outer periphery of the rotating shaft, an infusion channel is provided at the axis of the rotating shaft, and a plurality of liquid outlets connected to the infusion channel are provided on the outer periphery of the rotating shaft; the dosing mechanism is located above the stirring mechanism, and comprises an end cap detachably connected to the mixing pipe, and a dosing tube arranged on the end cap, wherein the dosing tube extends into the infusion channel; wherein the guide plate is used to guide the water flow to one side of the stirring mechanism, so that the water flow impacts the blades away from the end of the rotating shaft.

[0006] In the above technical solution, when water production is carried out, water flows in from the water inlet pipe, enters the mixing pipe, and is guided to one side of the stirring mechanism under the action of the guide plate. The rotation of the blades is driven by the power of the water flow. While the blades are rotating, the drug feeding tube puts the drug liquid into the infusion channel. The drug liquid in the infusion channel flows out from the liquid outlet to the mixing pipe and enters the water flow, and is mixed with the water flow under the stirring of the blades.

[0007] On the one hand, the utility model, through the design of the mixing tube, stirring mechanism and dosing mechanism, enables the water flow to be uniformly mixed with the liquid medicine when flowing through the mixing tube. It has a compact structure and occupies a small area. Without the need for external power, the water flow and stirring mechanism can cause the water flow to produce cutting, shearing, rotation and remixing of the liquid. The added liquid medicine can be quickly and evenly diffused throughout the water body, effectively improving the mixing efficiency of the water body and saving energy. On the other hand, through the design of the guide plate, the water flow is effectively guided to one side of the stirring mechanism, forming a directional impact. This impact not only enhances the turbulence of the water flow, but also causes the blade to produce a strong stirring effect at the end away from the rotating shaft. Combined with the rotating action of multiple blades on the rotating shaft, it ensures the rapid dispersion and uniform mixing of materials in the water, greatly improving the mixing efficiency.

[0008] Optionally, in a possible implementation, a side of the guide plate close to the water inlet pipe is a plane, and a side of the guide plate close to the stirring mechanism is an arc-shaped surface.

[0009] In the above technical solution, the flat side of the deflector ensures that water enters the water inlet pipe and strikes the deflector smoothly, reducing water turbulence and energy loss, and improving water utilization efficiency. The curved side of the deflector not only forms a water storage area, but also accelerates mixing with the liquid medicine when the water hits it, further stirring it. It also serves as a diversion device, redirecting the water flow and reducing turbulence.

[0010] Optionally, in a possible implementation, a limiting sleeve is provided on the side of the end cover facing the interior of the mixing tube, one end of the rotating shaft is rotatably disposed on the mounting seat via a bearing, and the other end is movably clamped in the limiting sleeve.

[0011] In this technical solution, the limiting sleeve and mounting base work together to provide a fixed axial constraint for the rotating shaft, ensuring that the shaft will not deviate from the predetermined trajectory due to uneven force or vibration during rotation, thereby improving the rotating shaft's rotational stability and mixing efficiency. The limiting sleeve design also simplifies the installation process of the rotating shaft. Simply secure one end of the shaft to the mounting base via a bearing, and the other end easily snaps into the limiting sleeve, eliminating the need for complex adjustment and calibration, and facilitating subsequent maintenance and replacement.

[0012] Optionally, in a possible implementation, an inclined turning surface is provided on one end of the inner side surface of the limiting sleeve away from the end cover.

[0013] In the above technical solution, the design of the inclined turning surface can expand the bottom opening of the limiting sleeve, so that the bottom opening of the limiting sleeve has a gradual structure from large to small, which can facilitate the alignment installation with the rotating shaft and improve the installation convenience with the rotating shaft.

[0014] Optionally, in a possible implementation, a wear-resistant gasket in a circular shape is provided on the inner side surface of the limiting sleeve, and the wear-resistant gasket is located between the inner side surface of the limiting sleeve and the outer side surface of the rotating shaft.

[0015] In this technical solution, the wear-resistant gasket effectively isolates the limiting sleeve from direct contact with the rotating shaft, significantly reducing friction and wear between them and significantly extending the service life of the limiting sleeve and the rotating shaft. The wear-resistant gasket also acts as a buffer layer, absorbing vibration and impact generated during the rotating shaft's rotation, reducing friction-induced noise and improving the smoothness and quietness of the equipment's operation.

[0016] Optionally, in a possible implementation, a plurality of the liquid outlets are provided between each of two adjacent blades, and the plurality of the liquid outlets are arranged at intervals along the length direction of the rotating shaft.

[0017] In this technical solution, multiple liquid outlets spaced along the length of the rotating shaft ensure a more even distribution of liquid within the mixing tube, avoiding localized concentration fluctuations, thereby improving mixing efficiency and product quality. The multiple outlets allow the liquid to enter the mixing tube in a multi-point spray pattern, resulting in more complete contact and mixing with the material, enhancing mixing uniformity and effectiveness.

[0018] Optionally, in a possible implementation, a check mechanism is further included for controlling the rotation of the rotating shaft in a single direction, the check mechanism includes a gear disk fixedly mounted on the rotating shaft, a fixed block arranged on the mounting seat, and a limit member arranged on the fixed block, the limit member is used to limit the rotation of the gear disk so that the gear disk can only rotate in one direction.

[0019] In this technical solution, the stopper mechanism, through the cooperation of the stopper and the toothed disc, ensures that the shaft can only rotate in a single direction, effectively preventing reverse rotation caused by misoperation or external factors, ensuring the normal operation and safety of the equipment. Furthermore, the unidirectionally rotating blades ensure orderly flow and mixing of materials within the mixing tube, avoiding uneven mixing or material accumulation caused by reverse rotation, thereby improving mixing efficiency and product quality.

[0020] Optionally, in a possible implementation, a limiting portion and an inclined portion are provided in the tooth groove of the toothed disc, the limiting unit includes a slider and a spring, a slot is provided on the side of the fixed block facing the toothed disc, the slider is slidably clamped in the slot, the spring is provided in the slot and abuts against the slider, and a limiting surface and an inclined surface matching the limiting portion and the inclined portion are provided at one end of the slider close to the toothed disc.

[0021] In the above technical solution, during normal rotation, the slider can be stuck between the tooth grooves of the gear disc under the action of the spring. When the gear disc rotates in the first direction, the inclined portion in the tooth groove will squeeze the inclined surface of the slider, and the slider will slide along the slot under the action of the inclined portion, that is, the slider will retract into the slot. At this time, the spring will be squeezed by the slider and shrink; when the gear disc rotates in the second direction, due to the action of the limiting portion and the limiting surface, the tooth groove and the slider will form a stuck structure and cannot rotate further, thereby realizing the unidirectional rotation of the gear disc.

[0022] Optionally, in a possible implementation, a transparent glass plate is provided on the end cover, and the transparent glass plate is located directly above the stirring mechanism.

[0023] In the above technical solution, the transparent glass panel allows users to directly observe the working status of the stirring mechanism and the mixing process of the materials without opening the equipment. This helps maintenance personnel to promptly detect problems such as material blockage and uneven mixing, so that they can quickly take appropriate measures to ensure mixing quality and production efficiency.

[0024] Optionally, in a possible implementation, one end of the drug administration tube is located in the mixing tube, and the other end is connected to the output end of the drug administration device through a connector.

[0025] In this technical solution, the direct connection between the dosing device and the dosing tube allows for precise control of drug delivery, avoiding overdosage or underdosage, ensuring the desired drug concentration during the mixing process, and thus improving product quality and consistency. Furthermore, the coupling facilitates disassembly of the dosing tube, thereby facilitating the removal and assembly of the end cap and subsequent repair and maintenance.

DETAILED DESCRIPTION

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0036] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without creative work are within the scope of protection of the present application.

[0037] Please refer to Figure 1 、 Figure 3 and Figure 5The present embodiment provides a pipeline mixer for water production, comprising a water inlet pipe 1, a mixing pipe 2, and a water outlet pipe 3 connected in sequence, and further comprising: a guide plate 4 and a stirring mechanism 5, and a dosing mechanism 6, which are sequentially arranged in the mixing pipe 2 along the direction of water flow. The stirring mechanism 5 comprises a mounting seat 51 provided on the inner wall of the mixing pipe 2, a rotating shaft 52 rotatably arranged on the mounting seat 51 and perpendicular to the direction of water flow, and a plurality of blades 53 arranged on the outer periphery of the rotating shaft 52. An infusion channel 521 is provided at the axis of the rotating shaft 52, and a plurality of liquid outlets 522 connected to the infusion channel 521 are provided on the outer periphery of the rotating shaft 52. The dosing mechanism 6 is located above the stirring mechanism 5 and comprises an end cap 61 detachably connected to the mixing pipe 2, and a dosing tube 62 arranged on the end cap 61, and the dosing tube 62 extends into the infusion channel 521. The guide plate 4 is used to guide the water flow to one side of the stirring mechanism 5 so that the water flow impacts the blades 53 away from the end of the rotating shaft 52.

[0038] Specifically, the water inlet pipe 1, mixing pipe 2, and outlet pipe 3 are detachably connected via flanges. A guide plate 4 directs the water flow toward one side of the stirring mechanism 5. In practice, one end of the guide plate 4 can be fixedly mounted on the sidewall of the mixing pipe 2, while the other end can be open and suspended. This suspended end can be located below the rotating shaft 52, i.e., offset from the rotating shaft 52 by a certain distance.

[0039] In this embodiment, when water production is carried out, water flows in from the water inlet pipe 1, enters the mixing pipe 2, and is guided to one side of the stirring mechanism 5 by the action of the guide plate 4. The blade 53 is driven to rotate by the power of the water flow. As the blade 53 rotates, the drug feeding tube 62 injects the drug solution into the infusion channel 521. The drug solution in the infusion channel 521 flows out from the liquid outlet 522 into the mixing pipe 2 and enters the water flow, and is mixed with the water flow under the stirring of the blade 53.

[0040] On the one hand, this embodiment, through the design of the mixing tube 2, the stirring mechanism 5 and the dosing mechanism 6, allows the water flow to be uniformly mixed with the liquid medicine while flowing through the mixing tube 2. It has a compact structure and occupies a small area. Without the need for external power, the water flow and the stirring mechanism 5 can cause the water flow to produce liquid cutting, shearing, rotation and remixing. The added liquid medicine can be quickly and evenly diffused throughout the water body, effectively improving the mixing efficiency of the water body and saving energy. On the other hand, through the design of the guide plate 4, the water flow is effectively guided to one side of the stirring mechanism 5, forming a directional impact. This impact not only increases the turbulence of the water flow, but also prompts the blades 53 to move away from the end of the rotating shaft 52 to produce a strong stirring effect. Combined with the rotation of the multiple blades 53 on the rotating shaft 52, it ensures the rapid dispersion and uniform mixing of the materials in the water, greatly improving the mixing efficiency.

[0041] Please refer to Figure 3In this embodiment, the side of the guide plate 4 closest to the water inlet pipe 1 is flat, and the side of the guide plate 4 closest to the stirring mechanism 5 is curved. The flat side of the guide plate 4 is inclined relative to the direction of water flow. After entering the mixing pipe 2, the water contacts the flat side of the guide plate 4 and flows along the guide plate 4, thereby reducing the water flow rate while increasing the water flow velocity, thereby enhancing the water flow dynamics.

[0042] The flat side of the deflector plate 4 ensures that water entering from the water inlet pipe 1 can smoothly impact the deflector plate 4, reducing water turbulence and energy loss, and improving water utilization efficiency. The curved side of the deflector plate 4 not only forms a water storage area, but also accelerates mixing with the liquid medicine when the water hits the water storage area, further stirring the liquid medicine. It also serves as a diversion function, redirecting the water flow and reducing turbulence.

[0043] Please refer to Figure 1 and Figure 2 In this embodiment, a limiting sleeve 611 is provided on the side of the end cap 61 facing the interior of the mixing tube 2. One end of the rotating shaft 52 is rotatably mounted on the mounting base 51 via a bearing 511, while the other end is movably engaged within the limiting sleeve 611. The axis of the limiting sleeve 611 coincides with the axis of the rotating shaft 52, so that the rotating shaft 52 does not interfere with the limiting sleeve 611 during rotation.

[0044] The limiting sleeve 611 and the mounting base 51 work together to provide a fixed axial constraint for the rotating shaft 52, ensuring that the rotating shaft 52 does not deviate from its predetermined trajectory due to uneven force or vibration during rotation, thereby improving the rotational stability and mixing efficiency of the rotating shaft 52. The design of the limiting sleeve 611 also simplifies the installation process of the rotating shaft 52. Simply secure one end of the rotating shaft 52 to the mounting base 51 via the bearing 511, and the other end easily snaps into the limiting sleeve 611, eliminating the need for complex adjustment and calibration, and facilitating subsequent maintenance and replacement.

[0045] It should be noted that the rotating shaft 52 of this embodiment is perpendicular to the direction of water flow, that is, perpendicular to the mixing tube 2. This arrangement allows the end cover 61 to be arranged on the outer peripheral side of the mixing tube 2. On the one hand, it is convenient for maintenance. After opening the end cover 61, the operation of the stirring mechanism 5 can be observed without disassembling the entire mixing tube 2; on the other hand, it is also convenient for adding liquid medicine. The medicine feeding tube 62 can be directly fixed on the end cover 61. When the end cover 61 is removed, the medicine feeding tube 62 can be removed simultaneously, which greatly facilitates the replacement and maintenance of the medicine feeding tube 62.

[0046] In this embodiment, an inclined transition surface is provided on the inner side of the limiting sleeve 611 at one end away from the end cap 61. The inclined transition surface can enlarge the bottom opening of the limiting sleeve 611, so that the bottom opening of the limiting sleeve 611 has a gradual structure from large to small, which can facilitate the alignment and installation with the rotating shaft 52, thereby improving the convenience of installation with the rotating shaft 52.

[0047] In this embodiment, a circular wear-resistant gasket 612 is provided on the inner side of the limiting sleeve 611. The wear-resistant gasket 612 is located between the inner side of the limiting sleeve 611 and the outer side of the rotating shaft 52. The wear-resistant gasket 612 is made of a highly wear-resistant material, such as ceramic, corundum wear-resistant material, silicon carbide, tungsten carbide, etc.

[0048] Wear-resistant gasket 612 effectively isolates the limiting sleeve 611 from direct contact with the rotating shaft 52, significantly reducing friction and wear between them and significantly extending the service life of the limiting sleeve 611 and the rotating shaft 52. Wear-resistant gasket 612 also acts as a buffer layer, absorbing vibration and impact generated during the rotation of the rotating shaft 52, reducing noise caused by friction and improving the smoothness and quietness of the device's operation.

[0049] Please refer to Figure 1 In this embodiment, multiple liquid outlets 522 are provided between each adjacent blade 53, and the multiple liquid outlets 522 are spaced apart along the length of the rotating shaft 52. The liquid outlets 522 are truncated cone-shaped structures with gradually decreasing diameters. The end of the liquid outlet 522 connected to the infusion channel 521 has a large diameter end, and the end connected to the mixing tube 2 has a small diameter end. This arrangement can effectively increase the flow rate of the liquid medicine and improve the liquid discharge efficiency.

[0050] This embodiment ensures that the liquid is more evenly distributed within the mixing tube 2 by providing multiple liquid outlets 522 spaced apart along the length of the rotating shaft 52, thereby avoiding the phenomenon of localized excessive or insufficient concentration, thereby improving mixing efficiency and product quality. The provision of multiple liquid outlets 522 allows the liquid to enter the mixing tube 2 in a multi-point spraying manner, allowing for more complete contact and mixing with the material, thereby enhancing the uniformity and effectiveness of the mixing. In addition, the dispersed provision of multiple liquid outlets 522 reduces the possibility of clogging of a single liquid outlet 522. Even if a liquid outlet 522 becomes clogged, it will not affect the normal operation of other liquid outlets 522, thereby ensuring the continued stable operation of the equipment.

[0051] Please refer to Figure 1 、 Figure 4 and Figure 5The pipeline mixer of this embodiment further includes a check mechanism 7 for controlling the rotation of the rotating shaft 52 in a single direction. The check mechanism 7 includes a toothed disc 71 fixedly mounted on the rotating shaft 52, a fixing block 72 disposed on the mounting base 51, and a stopper disposed on the fixing block 72. The stopper is used to limit the rotation of the toothed disc 71, so that the toothed disc 71 can rotate in only one direction. The toothed disc 71 is close to the mounting base 51, and the stopper abuts against the toothed disc 71 to limit the toothed disc 71 to one-way rotation.

[0052] The cooperation between the stopper and the toothed disc 71 in the check mechanism 7 ensures that the rotating shaft 52 can only rotate in a single direction, effectively preventing reverse rotation caused by misoperation or external factors, ensuring the normal operation and safety of the equipment. This also prevents vibration and impact that may occur when the rotating shaft 52 rotates in the reverse direction, reducing wear and failure rate of the equipment, and improving its stability and durability. Furthermore, the unidirectionally rotating blades 53 ensure orderly flow and mixing of materials within the mixing tube 2, avoiding uneven mixing or material accumulation caused by reverse rotation, thereby improving mixing efficiency and product quality.

[0053] Please refer to Figure 7 In this embodiment, a limiting portion 711 and an inclined portion 712 are provided within the tooth groove of the toothed disc 71. The limiting unit 73 includes a slider 731 and a spring 732. A slot 721 is provided on the side of the fixed block 72 facing the toothed disc 71. The slider 731 is slidably engaged within the slot 721. The spring 732 is disposed within the slot 721 and abuts against the slider 731. The end of the slider 731 near the toothed disc 71 is provided with a limiting surface 7311 and an inclined surface 7312 that match the limiting portion 711 and the inclined portion 712. The slot 721 is a rectangular groove. The limiting surface 7311 on the slider 731 is flush with the inner side of the slot 721, while the inclined surface 7312 is inclined relative to the limiting surface 7311. Therefore, only when the inclined portion 712 on the toothed disc contacts the inclined surface 7312 does a force component on the inclined surface 7312 toward the slot 721 be generated, thereby pushing the slider 731 to slide.

[0054] When the toothed disc 71 rotates normally, the slider 731 can be stuck between the teeth of the toothed disc 71 under the action of the spring 732. When the toothed disc 71 rotates in the first direction, the inclined portion 712 in the toothed groove will squeeze the inclined surface 7312 of the slider 731, and make the slider 731 slide along the slot 721 under the action of the inclined portion 712, that is, the slider 731 will retract into the slot 721. At this time, the spring 732 will be squeezed by the slider 731 and shrink; when the toothed disc 71 rotates in the second direction, due to the action of the limiting portion 711 and the limiting surface 7311, the toothed groove and the slider 731 will form a stuck structure and cannot rotate further, thereby realizing the unidirectional rotation of the toothed disc 71.

[0055] In this embodiment, a transparent glass plate 613 is provided on the end cap 61, located directly above the stirring mechanism 5. The provision of transparent glass plate 613 allows the user to directly observe the operating status of the stirring mechanism 5 and the material mixing process without opening the equipment. This helps maintenance personnel promptly identify problems such as material blockages and uneven mixing, allowing them to quickly take appropriate measures to ensure mixing quality and production efficiency.

[0056] In this embodiment, one end of the dosing tube 62 is located within the mixing tube 2, and the other end is connected to the output of the dosing device via connector 8. This direct connection between the dosing device and the dosing tube 62 allows for precise control of drug delivery, avoiding overdosage or underdosage, ensuring the desired drug concentration during the mixing process, and thus improving product quality and consistency. Furthermore, the provision of a coupling facilitates removal of the dosing tube 62, thereby facilitating assembly and disassembly of the end cap 61 and subsequent repair and maintenance.
