Description

Technical Field

[0001] This utility model relates to the technical field of feeding mechanisms, specifically to a flocculant feeding mechanism for wastewater treatment. Background Technology

[0002] In wastewater treatment, flocculants are commonly used chemical agents to promote the aggregation and sedimentation of suspended particles, thereby purifying the water. The flocculant feeding mechanism is a key component of the wastewater treatment system; its function is to mix the flocculant with the wastewater in a specific ratio to ensure efficient flocculation. Common wastewater treatment flocculant feeding mechanisms consist of a feeding cylinder, inlet, outlet, solenoid valve, water injection port, and stirring assembly. The following drawbacks have been observed during their use:

[0003] 1. When adding flocculant to the feeding cylinder and mixing it with the liquid, if the flocculant clumps due to moisture absorption or improper storage, traditional stirring methods are insufficient to break up and disperse the clumps. This can lead to uneven mixing of the flocculant and the liquid, affecting the effectiveness of subsequent flocculation reactions, and may even result in waste of the agent or substandard water quality.

[0004] 2. Existing mixing components typically use a unidirectional rotating mixing shaft, which has a single mixing method and easily forms a fixed flow pattern in the feeding cylinder, resulting in insufficient mixing in certain areas.

[0005] 3. At room temperature, the dissolution and mixing speed of flocculants with liquids is relatively slow, especially for polymeric flocculants or high-concentration solutions.

[0006] Therefore, in view of this, the existing structure was studied and improved, and a wastewater treatment flocculant feeding mechanism was proposed. Utility Model Content

[0007] The technical problem to be solved by this invention is that flocculant agglomeration leads to uneven mixing, the stirring component rotates in one direction, resulting in poor stirring effect and slow mixing speed at room temperature.

[0008] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a wastewater treatment flocculant feeding mechanism, including a feeding cylinder, wherein an inlet and an outlet are fixedly and continuously provided at the top and bottom of the feeding cylinder, and a solenoid valve is provided at the outlet; a water inlet is fixedly and continuously provided on one side of the feeding cylinder; and a stirring assembly is provided inside the feeding cylinder.

[0009] The outer side of the feeding cylinder is fixedly covered with a heat insulation cylinder, and a heat insulation cavity is formed between the inner wall of the heat insulation cylinder and the outer side of the feeding cylinder. A hot air fan is fixedly and continuously installed on one side of the heat insulation cylinder.

[0010] A filter plate is fixedly installed at the feed inlet, and a dispersing component for breaking up agglomerated flocculants is installed at the top of the filter plate inside the feed inlet.

[0011] The mixing assembly includes a receiving plate fixedly disposed inside a feeding cylinder. A mixing cylinder is rotatably disposed between one side of the receiving plate and one side of the feeding cylinder. A mixing rod is rotatably disposed between the other side of the receiving plate and the other side of the feeding cylinder. Several mixing blades are fixedly disposed on both the mixing cylinder and the mixing rod. A rotating rod is fixedly disposed at one end of the mixing rod, and the rotating rod moves sequentially through the receiving plate and the mixing cylinder. A driving assembly is disposed on the other side of the feeding cylinder. The driving assembly drives the mixing cylinder and the mixing rod to rotate simultaneously, and the mixing cylinder and the mixing rod rotate in different directions.

[0012] As a further embodiment of this utility model: the dispersing component includes two rotating rods rotatably disposed in the feed inlet, and several dispersing blades are fixedly disposed on the rotating rods. Two meshing gears are rotatably disposed on one side of the feed inlet, and the corresponding gears are fixedly connected to the rotating rods through a connecting shaft, and the connecting shaft is rotatably disposed on the feed inlet. A motor is fixedly disposed on the other side of the feed inlet to drive one of the rotating rods to rotate.

[0013] As a further aspect of this utility model, the dispersing blade is provided with several through holes.

[0014] As a further embodiment of this utility model: the dispersing blades on the two rotating rods are arranged alternately.

[0015] As a further embodiment of this utility model: the driving assembly includes a shaft and a cylinder rotatably mounted on the feeding cylinder, with the shaft movably inserted into the cylinder. Two meshing gears are rotatably mounted on the other side of the feeding cylinder. Several tooth blocks are fixedly mounted on the cylinder, and these tooth blocks mesh with one of the gears. A gear is fixedly connected to one side of the other gear via a connecting rod. A gear is fixedly connected to one end of the shaft, and gears two and three mesh with each other. A receiving rod is fixedly mounted on the other side of the feeding cylinder, and a motor for driving gear three to rotate is fixedly mounted on the receiving rod.

[0016] As a further embodiment of this utility model: the shaft drives the rotating rod and the stirring rod to rotate, and the shaft cylinder drives the stirring cylinder to rotate.

[0017] Compared with the prior art, the advantages of this utility model are as follows:

[0018] 1. This utility model, through the combined arrangement of the dispersing component and the filter plate, can disperse the clumps of flocculant when it is added to the feed inlet. Qualified flocculant will pass through the filter plate into the feeding cylinder 1, while unqualified flocculant will remain at the feed inlet for further dispersing. This can prevent clumps of flocculant from entering the feeding cylinder 1 and causing poor mixing.

[0019] 2. By setting up a stirring rod, a rotating rod, a stirring cylinder, and a driving component on the stirring assembly, the driving component can control the different rotation directions of the stirring rod, the rotating rod, and the stirring cylinder, so that the stirring assembly does not rotate in one direction during operation, thereby ensuring that the flocculant and liquid in the feeding cylinder are mixed evenly.

[0020] 3. By setting up a hot air blower and an insulation chamber, the hot air blower can heat the insulation chamber when it is working, thereby heating the feeding cylinder, which increases the efficiency of flocculant and liquid mixing. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-4A wastewater treatment flocculant feeding mechanism includes a feeding cylinder 1. An inlet 101 and an outlet 102 are fixedly and continuously disposed at the top and bottom of the feeding cylinder 1, respectively. A solenoid valve is installed at the outlet 102 to control the discharge of the mixed liquid. A water inlet is fixedly and continuously disposed on one side of the feeding cylinder 1 to inject liquid into it. A stirring assembly 2 is disposed inside the feeding cylinder 1. The stirring assembly 2 includes a receiving plate 201 fixedly disposed inside the feeding cylinder 1, and a stirring drum is rotatably disposed between one side of the receiving plate 201 and one side inside the feeding cylinder 1. 202. A stirring rod 203 is rotatably arranged between the other side of the receiving plate 201 and the other side of the feeding cylinder 1. Several stirring blades 204 are fixedly arranged on both the stirring cylinder 202 and the stirring rod 203. A rotating rod 205 is fixedly arranged at one end of the stirring rod 203. The rotating rod 205 moves through the receiving plate 201 and the stirring cylinder 202 in sequence. A driving assembly 6 is arranged on the other side of the feeding cylinder 1. The driving assembly 6 drives the stirring cylinder 202 and the stirring rod 203 to rotate simultaneously. The stirring cylinder 202 and the stirring rod 203 rotate in different directions. The drive assembly 6 includes a shaft 601 and a shaft cylinder 602 rotatably mounted on the feeding cylinder 1. The shaft 601 is movably inserted into the shaft cylinder 602. The shaft 601 drives the rotating rod 205 and the stirring rod 203 to rotate, and the shaft cylinder 602 drives the stirring cylinder 202 to rotate. Two meshing gears 603 are rotatably mounted on the other side of the feeding cylinder 1. Several tooth blocks 604 are fixedly mounted on the shaft cylinder 602, and the several tooth blocks 604 are meshed with one of the gears 603. A gear 605 is fixedly connected to one side of the other gear 603 through a connecting rod. A gear 606 is fixedly connected to one end of the shaft 601, and the gear 605 meshes with the gear 606. A receiving rod 607 is fixedly mounted on the other side of the feeding cylinder 1, and a motor 608 that drives the gear 606 to rotate is fixedly mounted on the receiving rod 607. Motor 2 (608) drives gear 3 (606) to rotate. Since gear 2 (605) meshes with gear 3 (606), it can also drive gear 2 (605) to rotate. Because gear 2 (605) is fixedly connected to another gear 1 (603) via a connecting rod, its rotation also drives the other gear 1 (603) to rotate. Since the two gears 1 (603) mesh, several tooth blocks 604 mesh with one of the gears 1 (603), thus enabling both one gear 1 (603) and several tooth blocks 604 to rotate. Because gear 3... A shaft 601 is fixedly connected to a 606, and several toothed blocks 604 are fixedly connected to a cylinder 602, so that the shaft 601 and the cylinder 602 can rotate simultaneously, and the rotation directions of the shaft 601 and the cylinder 602 are different. Since the shaft 601 is fixedly connected to a rotating rod 205 and the cylinder 602 is fixedly connected to a stirring drum 202, the rotating rod 205 and the stirring drum 202 rotate simultaneously. At this time, the stirring rod 203 rotates in the opposite direction to the stirring drum 202, so that the stirring blades 204 in the feeding cylinder 1 are divided into two groups, and the rotation directions are different.

[0030] Please see Figure 1-2 The outer side of the feeding cylinder 1 is fixedly covered with a heat insulation cylinder 3. The inner wall of the heat insulation cylinder 3 and the outer side of the feeding cylinder 1 form a heat insulation cavity. A hot air blower 4 is fixedly and continuously installed on one side of the heat insulation cylinder 3. The hot air blower 4 can blow hot air into the heat insulation cavity, thereby heating the feeding cylinder 1 and accelerating the mixing rate of the flocculant with the liquid.

[0031] Please see Figure 1-2 A filter plate 103 is fixedly installed at the feed inlet 101. A dispersing component 5, which breaks up agglomerated flocculants, is installed at the top of the filter plate 103 inside the feed inlet 101. The dispersing component 5 includes two rotating rods 501 rotatably mounted inside the feed inlet 101. Several dispersing blades 502 are fixedly mounted on the rotating rods 501, and several through holes are provided on the blades 502. The dispersing blades 502 on the two rotating rods 501 are staggered. Two meshing gears 503 are rotatably mounted on one side of the feed inlet 101. Corresponding gears 503 are fixedly connected to the rotating rods 501 via connecting shafts, and the connecting shafts are rotatably mounted on the feed inlet 101. A motor 504, which drives one of the rotating rods 501 to rotate, is fixedly mounted on the other side of the feed inlet 101. The two gears 503 mesh with each other, causing them to rotate in different directions, thus enabling the two rotating rods 501 to rotate in opposite directions.

[0032] The working principle of this utility model:

[0033] When flocculant needs to be added to wastewater, first open the water inlet and add liquid into the feeding cylinder 1. Then add the flocculant to the inlet 101. At this time, motor 1 504, motor 2 608, and hot air blower 4 are all started. Motor 1 504 can drive one of the rotating rods 501 to rotate, causing one of the gears 4 503 to rotate, so that both gears 4 503 can rotate. However, the two gears 4 503 rotate in different directions. This can drive the two rotating rods 501 to rotate in opposite directions, so that the agglomerated flocculant can be broken up by the dispersing blades 502. The unagglomerated flocculant will enter the feeding cylinder 1 through the filter plate 103.

[0034] At this time, driven by motor 608, gear 606 rotates, causing gears 605, 603, and several gear blocks 604 to rotate. This causes shaft 601 and shaft cylinder 602 to rotate simultaneously, but in different directions. This causes stirring drum 202 and stirring rod 203 to rotate in different directions, thus stirring the flocculant and liquid. Hot air blower 4 heats the insulation cavity, thereby heating the feeding cylinder 1. This heats the flocculant and liquid during stirring, accelerating the mixing of the flocculant and liquid. After mixing, the discharge port 102 can be opened by solenoid valve, thus adding the mixed flocculant to the wastewater.

[0035] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
