Description

An easily disassembled pipeline dosing device Technical Field

[0001] This utility model relates to a pipeline dosing device that is easy to disassemble. It is applicable to the field of wastewater treatment technology. Background Technology

[0002] Coagulation and sedimentation are essential processes in wastewater treatment, often occurring at the very beginning of the process, and their effectiveness directly impacts the treatment results of subsequent steps. To ensure effective coagulation, coagulants are typically added to the wastewater, usually via pipe mixing. Simple pipe mixers are generally open in the wastewater pipe, allowing the coagulant to be added directly through the opening. After the coagulant is added to the wastewater pipe, it must be mixed with the wastewater to ensure optimal coagulation. Summary of the Invention

[0003] The technical problem to be solved by this utility model is: to solve the above-mentioned technical problem, this utility model provides a pipeline dosing device that is easy to disassemble.

[0004] The technical solution adopted in this utility model is: a pipeline dosing device that is easy to disassemble, connected to a wastewater pipeline, and has the following features:

[0005] A mixing pipe is connected to wastewater pipes at both ends, and a sleeve connecting the mixing pipe is made on the side wall of the mixing pipe.

[0006] The dosing pipe extends into the mixing pipe through a sleeve. The coagulant is added into the mixing pipe through the dosing pipe. The dosing pipe section extending into the mixing pipe is arranged along the length of the mixing pipe. The dosing pipe is fixedly installed on the mixing pipe through a flange structure.

[0007] Baffles are alternately arranged on the inner wall of the mixing pipe downstream of the dosing pipe.

[0008] The flange structure has a first flange fixedly installed at the end of the sleeve and a second flange fixedly fitted on the outer wall of the dosing pipe. When the dosing pipe is installed on the mixing pipe, the second flange on the dosing pipe moves to a position corresponding to the first flange on the sleeve. The first flange and the second flange are connected by bolts.

[0009] A rubber ring is placed between the first flange and the second flange.

[0010] The end of the dosing pipe that extends into the mixing pipe is equipped with a sealing cap, and the sidewall of the dosing pipe section arranged along the length of the mixing pipe is uniformly provided with discharge holes.

[0011] There are 4 to 8 discharge holes along the circumferential direction of the dosing pipe. The distance between two adjacent discharge holes along the length of the dosing pipe is 25 mm to 50 mm, and the diameter of the discharge hole is 5 mm to 15 mm.

[0012] The baffle is arranged toward the outlet end of the mixing pipe, and the angle between the baffle and the inner wall of the mixing pipe is 60° to 85°.

[0013] The baffle is elliptical in shape.

[0014] A third flange is fixedly installed at the inlet end of the mixing pipe, and the inlet end of the mixing pipe can be connected to the wastewater pipe through the third flange.

[0015] A fourth flange is fixedly installed at the outlet end of the mixing pipe, and the outlet end of the mixing pipe can be connected to the wastewater pipeline through the fourth flange.

[0016] The diameter of the middle part of the mixing tube is larger than the diameter of both ends of the mixing tube.

[0017] A fifth flange is fixedly installed at the inlet end of the dosing pipe, and the inlet end of the dosing pipe can be connected to the coagulant supply equipment through the fifth flange.

[0018] The beneficial effects of this utility model are as follows: By setting a third flange and a fourth flange at the inlet and outlet ends of the mixing pipe, it is convenient to connect the mixing pipe to the wastewater pipeline through the flanges. By installing a sleeve on the side wall of the mixing pipe and fixing a first flange at the end of the sleeve, it is convenient for the dosing pipe connected to the feeding equipment to extend into the mixing pipe through the sleeve. By fixing a second flange to the dosing pipe, it is easy to move the second flange on the dosing pipe to the corresponding position of the first flange on the sleeve after the dosing pipe is installed in the mixing pipe. The first flange and the second flange are then connected by bolts, enabling quick disassembly and fixing of the dosing pipe to the mixing pipe. This greatly improves the convenience of equipment maintenance and cleaning. At the same time, the rubber ring between the first flange and the second flange provides a good sealing effect. This invention also features a sealing cap at the end of the dosing pipe and a discharge hole on the side wall of the dosing pipe. This facilitates the formation of a "high resistance" dosing system for the coagulant in the dosing pipe under the action of the sealing cap, allowing the agent to be evenly discharged from the discharge hole on the side wall of the dosing pipe, which is conducive to the mixing of the coagulant with the wastewater in the wastewater pipeline. Furthermore, the invention incorporates a baffle in the mixing pipe to disturb the water flow in the mixing pipe, changing the flow pattern in the wastewater pipeline and promoting mixing.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0026] Example 1 is a pipeline dosing device that is easy to disassemble, and has the following features:

[0027] Mixing pipe 1, both ends of mixing pipe 1 are connected to wastewater pipes, and a sleeve 1-1 connecting mixing pipe 1 is made on the side wall of mixing pipe 1;

[0028] Dosing pipe 2 extends into mixing pipe 1 through sleeve 1-1. Coagulant is added into mixing pipe 1 through dosing pipe 2. The section of dosing pipe 2 extending into mixing pipe 1 is arranged along the length of mixing pipe 1. Dosing pipe 2 is fixedly installed on mixing pipe 1 through flange structure 3.

[0029] Baffles 4 are alternately arranged on the inner wall of the mixing pipe 1 downstream of the dosing pipe 2.

[0030] A third flange 1-2 is fixedly installed at the inlet end of the mixing pipe 1, and the inlet end of the mixing pipe 1 can be connected to the wastewater pipe through the third flange 1-2.

[0031] A fourth flange 1-3 is fixedly installed at the outlet end of the mixing pipe 1, and the outlet end of the mixing pipe 1 can be connected to the wastewater pipe through the fourth flange 1-3.

[0032] A fifth flange 2-3 is fixedly installed at the inlet end of the dosing pipe 2, and the inlet end of the dosing pipe 2 can be connected to the coagulant feeding equipment through the fifth flange 2-3.

[0033] In this embodiment, the diameter of the middle part of the mixing tube 1 is larger than the diameter of both ends of the mixing tube 1. As a result, the flow rate inside the mixing tube 1 is slower, resulting in a better mixing effect.

[0034] Thus, in this embodiment, the third flange 1-2 and the fourth flange 1-3 facilitate the connection of the mixing pipe 1 to the wastewater pipeline, and the fifth flange 2-3 facilitates the connection of the dosing pipe 2 to the feeding equipment. The dosing pipe 2 can extend into the mixing pipe 1 through the sleeve 1-1. After the dosing pipe 2 extends to the corresponding position in the mixing pipe 1, the flange structure 3 can fix the dosing pipe 2 to the mixing pipe 1. The baffle 4 inside the mixing pipe 1 can disturb the water flow in the mixing pipe 1. The feeding equipment supplies coagulant into the mixing pipe 1 through the dosing pipe 2, and under the disturbance effect of the baffle 4 inside the mixing pipe 1, the coagulant and the wastewater in the mixing pipe 1 are uniformly mixed, improving the mixing efficiency.

[0035] In this embodiment, the diameter of the sleeve 1-1 is larger than the diameter of the dosing tube 2, so that the dosing tube 2, which is easy to bend, can extend into the mixing tube 1 through the sleeve 1-1.

[0036] Example 2 is a pipeline dosing device that is easy to disassemble. Based on Example 1, in this example, the flange structure 3 has a first flange 3-1 fixedly installed at the end of the sleeve 1-1 and a second flange 3-2 fixedly fitted on the outer wall of the dosing pipe 2. When the dosing pipe 2 is installed on the mixing pipe 1, the second flange 3-2 on the dosing pipe 2 moves to the position corresponding to the first flange 3-1 on the sleeve 1-1. The first flange 3-1 and the second flange 3-2 are connected by bolts 3-3.

[0037] The dosing pipe 2 can be quickly disassembled and fixedly installed on the mixing pipe 1 via the first flange 3-1 and the second flange 3-2, greatly improving the ease of equipment maintenance and cleaning and extending the service life of the equipment. A rubber ring 3-4 is arranged between the first flange 3-1 and the second flange 3-2. Thus, when the dosing pipe 2 is inserted into the corresponding position on the mixing pipe 1, the second flange 3-2 on the dosing pipe 2 moves to the corresponding position of the first flange 3-1 on the sleeve 1-1. Tightening the bolts 3-3 connects the first flange 3-1 and the second flange 3-2, thus fixing the dosing pipe 2 inside the mixing pipe 1. The rubber ring 3-4 between the first flange 3-1 and the second flange 3-2 provides good sealing performance, effectively preventing water leakage between the two flanges.

[0038] Example 3 is a pipeline dosing device that is easy to disassemble. Based on Example 1, in this example, the end of the dosing pipe 2 that extends into the mixing pipe 1 is provided with a sealing cap 2-1, and the side wall of the dosing pipe 2 section arranged along the length of the mixing pipe 1 is uniformly provided with discharge holes 2-2, forming a "high resistance" dosing system.

[0039] The diameter of the discharge hole 2-2 is 5mm to 15mm, and the distance between two adjacent discharge holes 2-2 along the length of the dosing pipe 2 is 25mm to 50mm.

[0040] The baffle 4 is arranged toward the outlet end of the mixing pipe 1, and the angle between the baffle 4 and the inner wall of the mixing pipe 1 is 60° to 85°.

[0041] The distance between two adjacent baffles 4 is 300mm to 800mm. In this way, when the water flows through the baffles 4 in the mixing pipe 1, the baffles 4 have a disturbing effect on the water flow, which facilitates the mixing of the coagulant and the water flow.

[0042] Example 4 is an easily disassembled pipeline dosing device, connected to a wastewater pipeline, which has the following features:

[0043] Mixing pipe 1, both ends of mixing pipe 1 are connected to wastewater pipes, and a sleeve 1-1 connecting mixing pipe 1 is made on the side wall of mixing pipe 1;

[0044] Dosing pipe 2 extends into mixing pipe 1 through sleeve 1-1. Coagulant is added into mixing pipe 1 through dosing pipe 2. The section of dosing pipe 2 extending into mixing pipe 1 is arranged along the length of mixing pipe 1. Dosing pipe 2 is fixedly installed on mixing pipe 1 through flange structure 3.

[0045] Baffles 4 are alternately arranged on the inner wall of the mixing pipe 1 downstream of the dosing pipe 2.

[0046] The flange structure 3 has a first flange 3-1 fixedly installed at the end of the sleeve 1-1 and a second flange 3-2 fixedly fitted on the outer wall of the dosing pipe 2. When the dosing pipe 2 is installed on the mixing pipe 1, the second flange 3-2 on the dosing pipe 2 moves to the position corresponding to the first flange 3-1 on the sleeve 1-1. The first flange 3-1 and the second flange 3-2 are connected by bolts 3-3.

[0047] A rubber ring 3-4 is arranged between the first flange 3-1 and the second flange 3-2.

[0048] The end of the dosing tube 2 that extends into the mixing tube 1 is provided with a sealing cap 2-1, and the side wall of the dosing tube 2 section arranged along the length of the mixing tube 1 is uniformly provided with discharge holes 2-2.

[0049] The diameter of the discharge hole 2-2 is 5mm to 15mm. The distance between two adjacent discharge holes 2-2 along the length of the dosing pipe 2 is 25mm to 50mm. There are 4 to 8 discharge holes 2-2 along the circumferential direction of the dosing pipe 2. In this embodiment, there are 6 discharge holes.

[0050] The baffle 4 is arranged toward the outlet end of the mixing pipe 1, and the included angle between the baffle 4 and the inner wall of the mixing pipe 1 is 60° to 85°.

[0051] The baffle 4 is elliptical in shape.

[0052] A third flange 1-2 is fixedly installed at the inlet end of the mixing pipe 1, and the inlet end of the mixing pipe 1 can be connected to the wastewater pipe through the third flange 1-2.

[0053] A fourth flange 1-3 is fixedly installed at the outlet end of the mixing pipe 1, and the outlet end of the mixing pipe 1 can be connected to the wastewater pipe through the fourth flange 1-3.

[0054] The diameter of the middle part of the mixing tube 1 is larger than the diameter of both ends of the mixing tube 1.

[0055] A fifth flange 2-3 is fixedly installed at the inlet end of the dosing pipe 2, and the inlet end of the dosing pipe 2 can be connected to the coagulant feeding equipment through the fifth flange 2-3.

[0056] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
