Description

Technical Field

[0001] The utility model relates to the technical field of sedimentation tank water treatment, and particularly relates to a mixing device for tap water coagulant. Background Technique

[0002] In the process of making tap water in a waterworks, it is required that the coagulant be quickly and evenly mixed with the water body after entering the water body, so that impurities and colloids in the water body are completely and quickly destabilized, and then the subsequent floc particles collide and adsorb with each other, ultimately ensuring the sedimentation effect.

[0003] At present, the main methods to ensure the rapid and uniform mixing of the coagulant and the water body are hydraulic stirring and mechanical stirring. Mechanical stirring is more common, and mechanical stirring mainly uses a mixer, which is generally arranged in the mixing tank at the inlet of the sedimentation tank. The motor power supporting the mixer is generally above 5KW, with high energy consumption and general actual stirring and mixing effect. Summary of the Utility Model

[0004] Aiming at the deficiencies of the above-mentioned prior art, the technical problem to be solved by the utility model is to provide a mixing device for tap water coagulant that can reduce energy consumption and improve the mixing efficiency of the coagulant and water.

[0005] To solve the above technical problem, a technical solution adopted by the utility model is: to provide a mixing device for tap water coagulant, which includes a medicine inlet pipe, an aggregate cylinder, and a medicine outlet mechanism that are connected in sequence along the medicine inlet direction.

Each medicine outlet pipe group includes at least three discharge pipes communicated with the distribution sleeve, and the length dimensions between adjacent two discharge pipes in each medicine outlet pipe group are set as an equal difference value; a propeller blade is connected to the distribution sleeve.

[0006] With the above structure, setting the propeller blade can drive the rotation by the water flow in the pool, reducing the energy consumption, and synchronously driving the distribution sleeve and the distribution pipe to rotate. The coagulant added from the medicine inlet pipe flows into the distribution sleeve through the aggregate cylinder and is discharged through the distribution pipe. Since the length dimensions between adjacent two discharge pipes in each medicine outlet pipe group are set as an equal difference value, under the condition of the rotation of the discharge pipe, the coagulant can reach different depth positions on the water flow cross-section, forming a pattern of adding the coagulant at multiple points, and the purpose of full and uniform mixing can be achieved under the premise of rotation, with a simple structure and convenient use.

[0008] In order to prevent the coagulant from leaking out and simplify the installation structure at the same time, preferably, a baffle is screwed on one side of the large hole end corresponding to the step hole on the collecting barrel, and a clearance hole is provided at the position of the baffle corresponding to the dividing sleeve. The dividing sleeve passes through the clearance hole, and the outlet end on one side of the dividing sleeve is sleeve-connected with the middle hole of the bearing, and the outlet end on the other side is sleeve-connected with the propeller blade.

[0009] In order to facilitate installation and fixation and simplify the structure, preferably, a horizontally extending connecting rod is provided in the middle of the material distribution sleeve, a connecting tube is sleeved on the outer side of the connecting rod, and three propeller blades are evenly arranged along the circumferential direction on the outer wall of the connecting tube; a locking nut abutting against the connecting tube is threaded at the protruding end of the connecting rod.

[0010] In order to reduce installation wear and ensure connection stability, it is preferred that a washer is sleeved on the connecting rod at a position corresponding to the locking nut and the connecting tube, one side of the washer abuts against the outer end face of the connecting tube, and the other side of the washer is pressed and abutted against the end face of the corresponding end of the locking nut.

[0011] In order to better improve the efficiency of the rotational mixing of the coagulant, preferably, a boss is provided on the outer side wall of each of the discharge pipes, and the outer side wall of the boss is a conical structure that is wide inside and narrow outside.

[0012] Beneficial effects: The utility model is provided with a propeller blade driven to rotate by water flow, and synchronously drives the discharge pipe connected to the feed pipe to rotate, which not only reduces energy consumption, but also forms a pattern of adding coagulant at multiple points at different depths of the water flow section, improves the mixing efficiency of the coagulant, and can achieve the purpose of sufficient and uniform mixing.

[0019] Depend on Figure 1 and Figure 2 As shown, the utility model includes a drug feed pipe 1, a collecting barrel 2 and a drug discharge mechanism which are sequentially connected along the drug feed direction, the drug discharge mechanism includes a dividing sleeve 3 which is connected and sleeved with the collecting barrel 2, and two drug discharge pipe groups are symmetrically arranged on the outer wall of the dividing sleeve 3, each of the drug discharge pipe groups includes at least three discharge pipes 31 connected with the dividing sleeve 3, and the length dimensions between two adjacent discharge pipes 31 in each of the drug discharge pipe groups are set with equal differences; a propeller blade 4 is connected to the dividing sleeve 3.

[0020] Specifically, a step hole 20 is provided in the collecting barrel 2, and the small hole end of the step hole is connected to the medicine feed pipe 1, and a bearing 21 is provided in the large hole end of the step hole. A baffle 22 is screwed on one side of the collecting barrel 2 corresponding to the large hole end of the step hole 20, and a clearance hole 23 is provided on the baffle 22 at a position corresponding to the material distribution sleeve 3. The material distribution sleeve 3 passes through the clearance hole 23, and the outlet end on one side of the material distribution sleeve 3 is sleeve-connected with the middle hole of the bearing 21, and the outlet end on the other side is sleeve-connected with the propeller blade 4.

[0021] A horizontally extending connecting rod 32 is provided in the middle of the distribution sleeve 3, a connecting tube 33 is sleeved on the outer side of the connecting rod 32, and three propeller blades 4 are evenly arranged along the circumferential direction on the outer wall of the connecting tube 33; a locking nut 36 abutting against the connecting tube 33 is screwed on the protruding end of the connecting rod 32; a washer 34 is sleeved on the connecting rod 32 at a position corresponding to the locking nut 36 and the connecting tube 33, one side of the washer 34 abuts against the outer end face of the connecting tube 33, and the other side of the washer 34 is pressed and abutted against the end face of the corresponding end of the locking nut 36.

[0022] A boss 35 is provided on the outer side wall of each of the discharge pipes 31 , and the outer side wall of the boss 35 is a conical structure that is wide inside and narrow outside.

[0023] The operating principle of the utility model is as follows:

[0024] like Figures 1 to 2As shown, when in use, the collecting barrel 2 and the propeller blade 4 are placed as a whole in the water flow at the connecting position between the sedimentation tank and the mixing tank, and the feeding end of the medicine feeding pipe 1 is exposed to the water surface. At this time, driven by the water flow, the propeller blade 4 starts to rotate. Since one side of the gasket 34 abuts against the outer end face of the connecting barrel 33, and the other side of the gasket 34 is pressed and abutted against the end face of the corresponding end of the locking nut 36, the connecting rod 32, the distribution sleeve 3 and the distribution pipe 31 are synchronously driven to rotate.

[0025] While rotating, the coagulant flows into the collecting barrel 2 through the drug inlet pipe 1. Since a baffle 22 is screwed thereon and a clearance hole 23 is provided on the baffle 22 for the distribution sleeve 3 to pass through, the coagulant can be prevented from leaking out of the bearing 21 at the large hole end of the step hole 20 while ensuring the rotation of the distribution sleeve 3. The coagulant can only flow into the distribution sleeve 3 and then flow out through the distribution pipe.

[0026] Since the lengths of two adjacent discharge pipes 31 in each discharge pipe group are set with equidistant values, under the condition of rotation of the discharge pipe 31, the coagulant flowing out of the distribution pipe 31 can reach different depth positions on the water flow section, forming a multi-point coagulant addition pattern, and the purpose of fully uniform mixing can be achieved under the premise of rotation.

[0027] In addition, while the distribution pipe 31 is rotating, it also plays a stirring role in the mixture of the coagulant and water. At the same time, a boss 35 is provided on the distribution pipe 31. The outer wall of the boss 35 is a conical structure that is wide inside and narrow outside. The conical structure forms an inclined cutting form on the water section in the direction of rotation, and the cutting position is filled with water. A local vortex is formed while stirring. Such repeated rotation can accelerate the mixing efficiency of the coagulant and water.

[0028] It should be noted that during the implementation of this embodiment, if the coagulant is injected for a short time, it is only necessary to manually hold the drug feed pipe 1 to put the aggregate barrel 2 and the propeller blade 4 as a whole into the water; if it needs to be placed in a standby state for a long time, it is only necessary to set a fixing component (not marked) at the edge of the pool where the sedimentation tank and the mixing tank are connected to fix the drug feed pipe 1, and at the same time ensure that the aggregate barrel 2 and the propeller blade 4 are placed in the water as a whole, which is flexible to use.
