Description

Technical Field

[0001] The utility model relates to the field of water treatment equipment, in particular to a coagulant feeding device. Background Art

[0002] In water treatment practices in the thermal power industry, precise coagulant dosing is essential for maintaining efficient and clean power generation. Traditional manual dosing methods, cumbersome and labor-intensive, are no longer able to meet the efficiency and environmental demands of modern power generation. With the advancement of automation technology, electric dosing systems, with their precise control and efficient operation, are becoming a mainstream trend in industry upgrades. However, in the transition from manual dosing systems to electric dosing systems, rapid technological innovation without significantly altering the existing dosing silos and workshop layout presents a pressing technical challenge. Existing technologies for such retrofits often face long construction periods, high costs, and significant disruptions to normal production activities. Traditional retrofits typically involve complex demolition and reconstruction, significantly disrupting existing facilities and potentially leading to extended downtime, impacting the power plant's ability to maintain continuous power supply, and consequently, compromising both economic efficiency and environmental compliance. Utility Model Content

[0003] The utility model is intended to provide a coagulant feeding device to reduce changes to the dosing bin and workshop layout, reduce interference with existing facilities, and achieve rapid and lossless docking of the electric-driven dosing system with the existing dosing bin and workshop.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a coagulant feeding device, comprising a feeding unit for transporting coagulant, an opening and closing unit for opening and closing the hatch of the dosing bin, and a material moving mechanism for lifting and moving the feeding unit, the feeding unit comprising a feeding bucket, a lifting part hinged on the upper part of the feeding bucket, a dumping part fixed on the lower part of the feeding bucket, the material moving mechanism comprising a rotating unit and a lifting unit, the rotating unit comprising a boom rotatably arranged on the ceiling of the workshop, the lifting unit comprising a winch fixedly arranged on the top of the dosing bin, the winch being equipped with a first drum and a second drum which are independently controlled, a No. 1 steel wire and a No. 2 steel wire being wound on the first drum and the second drum respectively, the free ends of the No. 1 steel wire and the No. 2 steel wire sliding through the boom and being fixedly connected to the lifting part and the dumping part respectively.

[0005] The beneficial effects of this scheme are as follows: 1. The only places that need to be modified in this scheme are the hatch of the dosing bin, the installation position of the winch, and the installation position of the boom in the workshop. Except for the modification of the hatch, the normal production activities are less affected; 2. The original dosing bin and ancillary equipment are not involved in the initial stage of the modification. The winch and lifting unit can be installed during the dosing interval. The hatch part of the dosing bin can be modified in the later stage, which has little impact on the dosing bin and its ancillary facilities. At the same time, the boom and winch in this scheme can be produced and assembled first, and then transported to the production workshop for installation after assembly. Most of the installation work can be completed outside the production workshop, and the impact on the production workshop is short. 3. When in use, the loading unit is lifted to the plane where the top of the dosing bin is located by using the No. 1 steel wire, and the loading unit is transferred to the position of the hatch of the dosing bin by rotating the boom. The hatch of the dosing bin is opened by the opening and closing unit, and the original manual dosing system is replaced by an electric dosing system, which reduces the investment in labor costs.

[0006] Furthermore, the rotating unit also includes a servo motor. A rotating part is welded at the center position of the upper end of the boom. The rotating part is rotatably arranged on the ceiling of the workshop and fixedly connected to the output shaft of the servo motor.

[0007] Beneficial effect: The servo motor drives the rotating part to rotate, and then drives the boom to rotate, with higher precision and better controllability.

[0008] Furthermore, a suspension guide assembly is fixedly provided at the bottom of the boom, and the suspension guide assembly includes a suspension assembly and a guide assembly. The suspension assembly is fixedly provided at the bottom of one end of the boom, and the suspension assembly includes a first suspension ring and a second suspension ring. The first suspension ring and the second suspension ring are both fixed on the central axis of the bottom of the boom; the guide assembly includes a plurality of guide rings, and the guide rings are arranged from the boom end away from the suspension assembly toward the direction of the suspension assembly, and the free ends of the No. 1 steel wire and the No. 2 steel wire slide through the guide rings and the suspension rings.

[0009] Beneficial effect: No. 1 steel wire and No. 2 steel wire are passed from one end of the boom to the other end. When lifting, both ends of the boom are evenly stressed, avoiding eccentric stress on the rotating part, reducing wear of the rotating part, increasing the service life of the rotating part, and reducing maintenance costs.

[0010] Furthermore, the guide rings are equidistantly fixed on both sides of the central axis of the bottom of the boom to form a first guide channel and a second guide channel. The free end of the No. 1 steel wire passes through the first guide channel and the first suspension ring and is fixedly connected to the lifting part, and the free end of the No. 2 steel wire passes through the second guide channel and the second suspension ring and is fixedly connected to the tilting part.

[0011] Beneficial effect: The No. 1 steel wire and the No. 2 steel wire are separated by the first guide channel and the second guide channel, so as to avoid entanglement of the No. 1 steel wire and the No. 2 steel wire during use, which may cause the equipment to fail to operate normally.

[0012] Furthermore, the opening and closing unit includes a servo motor, and the output shaft of the servo motor is fixedly connected to the rotating shaft of the cabin door.

[0013] Beneficial effects: Controlling the opening and closing of the hatch by a servo motor is conducive to setting the coordination between the opening and closing unit and the material transfer mechanism through program setting, reducing the operating steps. The operator only needs to transfer the coagulant to the feeding unit and start the power supply. The material transfer mechanism can move the feeding unit to the expected position. At the same time, the opening and closing unit opens the hatch to complete the feeding work.

[0014] Furthermore, the loading barrel includes a cover body and a barrel body, the cover body is fixedly covered on the barrel body, the cover body includes a cover body and a tilting cover, the tilting cover is rotatably arranged on the cover body, the lifting part is hinged on the cover body, and the tilting part is fixedly arranged at the lower end of the barrel body.

[0015] Beneficial effects: Generally speaking, for coagulants with strong hygroscopicity, they are stored in polyethylene bags. The loading barrel is divided into a cover body and a barrel body. The operator can directly put the polyethylene bag containing a certain amount of coagulant into the barrel body, and turn the bag mouth of the polyethylene bag outward and put it on the opening of the barrel body, and then cover it with the cover body. When pouring, the pouring cover remains horizontal under the action of its own gravity, and a gap appears between the cover body and the pouring cover. The coagulant is poured out from the gap, reducing the contact between the coagulant and the air during the loading process. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Example 1

[0024] Example 1 is basically as shown in the attached Figure 1-3 As shown, Figure 1-3 The coagulant feeding device shown is used for feeding the dosing bin 1, and includes a feeding unit, an opening and closing unit and a material transfer mechanism, such as Figure 2 As shown, the loading unit includes a loading barrel 251 , a lifting portion 252 is hingedly connected to the upper portion of the loading barrel 251 , and a tilting portion 253 is symmetrically welded or clamped to the lower portion of the loading barrel 251 . In this embodiment, the tilting portion 253 is clamped to the lower portion of the loading barrel 251 .

[0025] like Figure 1 As shown, the dosing chamber 1 includes a hatch 11, which includes a rotating shaft. The hatch 11 is welded to the rotating shaft, and the rotating shaft is rotatably arranged on the top of the dosing chamber 1. The opening and closing unit includes a hatch motor 12, and the output shaft of the hatch motor 12 is fixedly connected to the rotating shaft through a coupling. The hatch motor 12 is a servo motor, so that the opening and closing of the hatch 11 is controlled by the hatch motor 12.

[0026] The material moving mechanism includes a rotating unit and a lifting unit. The rotating unit includes a servo motor and a boom 221. The servo motor is fixed to the ceiling of the workshop by bolts. The output shaft of the servo motor is keyed to a first bevel gear. A rotating part 222 is welded to the top middle part of the boom 221. The top end of the rotating part 222 is rotatably arranged on the ceiling of the workshop. A second bevel gear is welded to the middle section of the rotating part 222. The first bevel gear is meshed with the second bevel gear, thereby driving the boom 221 to swing back and forth through the servo motor.

[0027] The bottom of the boom 221 is fixedly provided with a suspension guide assembly, which includes a suspension assembly and a guide assembly. Figure 3 As shown, the suspension assembly includes a first suspension ring 232 and a second suspension ring 242. The first suspension ring 232 and the second suspension ring 242 are located at the top of the loading barrel 251 and can reach the top of the hatch 11 through the rotation of the boom 221. The first suspension ring 232 and the second suspension ring 242 are both welded to one end of the central axis of the bottom of the boom 221.

[0028] like Figure 3 As shown, the guide assembly includes a first guide ring 231 and a second guide ring 241. The first guide ring 231 and the second guide ring 241 are respectively welded equidistantly on both sides of the central axis of the bottom of the suspension arm 221 from the end away from the suspension arm 221 toward the suspension assembly, forming a first guide channel and a second guide channel.

[0029] like Figure 1As shown, the lifting unit includes a winch, which is equipped with a first drum 211 and a second drum 212 that are independently controlled. The first drum 211 and the second drum 212 are respectively wound with a No. 1 steel wire and a No. 2 steel wire. The free end of the No. 1 steel wire passes through the first guide channel and the first suspension ring 232 and is fixedly connected to the lifting part 252, and the fixed connection method can be a clamp connection; the free end of the No. 2 steel wire passes through the second guide channel and the second suspension ring and is fixedly connected to the dumping part 253, and the fixed connection method can also be a clamp connection, so that the loading bucket 251 is lifted to the top of the dosing bin 1 by the No. 1 steel wire, and then the loading bucket 251 is transferred to the hatch 11 by the boom 221. After the hatch 11 is opened, the bottom of the loading bucket 251 is lifted by the No. 2 steel wire, so that the loading bucket 251 is dumped, and the coagulant in the loading bucket 251 is transferred to the dosing bin 1.

[0030] The specific implementation process is as follows:

[0031] When in use, first, put the coagulant into the loading bucket 251, and use the clamp to bind the free end of the No. 1 steel wire to the lifting part 252, and the free end of the No. 2 steel wire to the tilting part 253; then, start the winch, the first drum 211 rotates, the No. 1 steel wire is retracted, and the loading bucket 251 is raised to ensure that the bottom of the loading bucket 251 is higher than the highest height when the hatch 11 is opened. The boom 221 rotates to transfer the loading bucket 251 to the position of the hatch 11, and the hatch motor 12 is started to complete the opening of the hatch 11; Afterwards, the second drum 212 rotates to retract the No. 2 steel wire and complete the dumping of the loading bucket 251; after the dumping is completed, the hatch 11 is closed, the boom 221 is reset, and the first drum 211 and the second drum 212 are unwound, etc. are completed in sequence; if it is necessary to add coagulant again, the above process can be repeated until the addition is completed; after the addition is completed, the No. 1 steel wire and the No. 2 steel wire are separated from the lifting part 252 and the dumping part 253, and the loading bucket 251 is cleaned so that the loading bucket 251 remains dry and clean.

[0032] Example 2

[0033] Example 2 is basically the same as Example 1, except that Figure 4 As shown, the loading barrel 251 includes a cover body and a barrel body 2513. The cover body and the barrel body 2513 are separate structures. The cover body is covered on the barrel body 2513 and connected by bolts to ensure the stability of the connection and avoid the cover body and the barrel body 2513 from being separated during the lifting process, causing the coagulant to spill out.

[0034] When in use, the outer packaging of the coagulant can be placed in the barrel body 2513, and the opening of the outer packaging can be turned over and placed on the barrel body 2513 to reduce the turnover times of the coagulant, thereby reducing the moisture absorbed by the coagulant. The cover body includes a cover body 2511 and a tilting cover 2512. The tilting cover 2512 is rotatably set on the cover body 2511 and kept horizontal to reduce the gap between the tilting cover 2512 and the cover body 2511, reduce the contact between the loading barrel 251 and the air, and reduce the moisture absorbed by the coagulant during the transfer process. Figure 5 As shown, when the cover body 2511 is tilted, a gap appears between the tilting cover 2512 and the cover body 2511, and the coagulant in the loading barrel 251 is poured out through the gap.
