Description
Technical Field
The following description relates to an unpowered in-line mixing device, and more particularly to a unpowered in-line mixing device, a method of operating a unpowered in-line mixing device, and a water treatment system having at least two unpowered in-line mixing devices, wherein: the chemical injection unit assembly can be easily attached and detached, and can be inspected without suspending the water supply; and the chemical injection unit assembly may minimize an influence of a flow rate of the material mixed to flow in the unpowered in-pipe mixing device, a mixing ratio of the mixed material discharged from the unpowered in-pipe mixing device to the chemical may be measured by using the sampling unit assembly, and foreign substances deposited in the unpowered in-pipe mixing device may be effectively removed by using the openable cleaning hole.
Background
In a filter plant, a sewage treatment plant, a wastewater treatment plant, a pond, or the like, a chemical mixing apparatus is used to inject chemicals such as a disinfectant that disinfects raw water or purified water, or a flocculant that flocculates foreign matter. The chemical mixing device is connected to a raw water pipe through which raw water is supplied to a filter plant, a pond, etc., and uniformly mixes chemicals with the raw water so that water mixed with chemicals can be supplied to the filter plant, the pond, etc.
Korean registered utility model nos. 113114, 224737, and 275014 disclose chemical mixing devices that perform this function. In addition to these utility models, korean registered patent No. 916709 discloses a chemical mixing device in which the disadvantages of the chemical mixing device disclosed in these utility models are remedied.
The unpowered in-pipe mixing apparatus disclosed in korean registered patent No. 916709 is widely used for various related applications ranging from a filtration plant for purifying water to a sewage and wastewater purification facility. In particular, when used in sewage and wastewater purification facilities, the unpowered in-pipe mixing device has a drawback in that impurities adhered to the inside of the mixing device by a hydration reaction reduce the efficiency of the mixing device. Since the chemical inlet installed at the inlet of the mixing device in the unpowered pipe is a fixed type inlet and thus is not detachable, it is necessary to stop the operation of the sewage and wastewater purification facility to check the mixing device in the unpowered pipe, which makes the maintenance of the mixing device in the unpowered pipe inconvenient. Further, it is possible that the end of the pipe where the chemicals are injected into the unpowered in-pipe mixing device may be bent by the force of the rapid flow of the sewage and wastewater in the unpowered in-pipe mixing device. In particular, since the mixing ratio of chemicals discharged from the unpowered in-pipe mixing device to sewage and wastewater is unknown, data used to determine the amount of chemicals is obtained only empirically, making it difficult to mix chemicals efficiently. In addition, the unpowered in-pipe mixing device is configured as a single pipe, so that impurities in the unpowered in-pipe mixing device cannot be removed without stopping the operation of the purification facility.

Further, reference is made to korean patent No. 100916709 (unpowered in-pipe mixing device) previously filed and registered by the applicant of the present invention.
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the following drawings. In the drawings, like elements are denoted by like reference numerals.

Referring to fig. 1 to 4, the unpowered in-pipe mixing device 100 of the present invention comprises: an inlet pipe 110, a mixing pipe 120, and an outlet pipe 130 connected in series with each other; a chemical injection unit assembly 140 installed at the inlet pipe 110; a cleaning cap 150 mounted on the mixing pipe 120; and a sampling unit assembly 160 mounted to the discharge tube 130.
The general structure and operating principle of the unpowered in-pipe mixing device is described first, and the main concepts of the present invention are described in detail later.
The inlet pipe 110 has an opening on one side at which an inlet flange 111 is formed and a top at which at least two chemical injection holes 112 and 113 are formed. In the drawings, it is shown that the chemical injection unit assembly 140 has been inserted into the chemical injection holes 112 and 113. The inlet flange 111 and the outlet flange 131 described later are necessary for the installation of the unpowered in-pipe mixing device 100 in the existing pipeline of a filtration plant.
The mixing pipe 120 has: an opening on one side portion hermetically connected with an opening on the other side portion of the inlet pipe 110; a top portion at which the cleaning hole 121 is formed; and an interior in which a plurality of partition wall parts 123 are disposed, each partition wall part 123 having a plurality of discharge holes 123-1 and 123-2. The shape and function of the discharge holes 123-1 and 123-2 are described in korean registered patent No. 916709, and thus a detailed description thereof will be omitted.
The discharge pipe 130 has: an opening on one side portion which is hermetically connected with an opening on the other side portion of the mixing pipe 120; and an opening on the other side, at which the outlet flange 131 is formed.
Here, the airtight connection refers to a case where the inside is not exposed to the outside at the connection portion when two continuous pipes are connected. Referring to fig. 3, it can be seen that the mixing part 120 disposed at the center has the maximum diameter, and the diameter of the inlet pipe 110 and the outlet pipe 130 connected to both ends of the mixing pipe 120 is smaller than that of the mixing pipe 120. In this case, connection pieces 301 and 302 having a specific size are provided on both ends of the mixing pipe 120 from the outer circumferential surface toward the center, so that although the diameters are different, such difference does not cause exposure of the connection portions of the three pipes 110, 120, and 130.
As described above, the inlet pipe 110, the mixing pipe 120, and the discharge pipe 130, each having a specific space, are connected in series with each other, and a material to be mixed (hereinafter referred to as "raw water") is introduced from one opening of the inlet pipe (left side opening as viewed in fig. 4), passes through the mixing pipe 120, and is discharged to the other opening of the discharge pipe 130 (right side opening as viewed in fig. 4).
The chemical injection unit assembly 140 injects a chemical into the inlet pipe 110 through the chemical injection holes 112 and 113 formed at the top of the inlet pipe 110. The chemicals injected through the chemical injection unit assembly 140 are dispersed by the chemical dispersion unit 124 so that the chemicals can be effectively mixed with the raw water introduced from one opening of the inlet pipe. In the mixing pipe 120, a plurality of partition wall parts 123 including a plurality of discharge holes 123-1 and 123-2 are sequentially arranged in a traveling direction of raw water and chemicals, which are mixed while passing through the plurality of partition wall parts 123. The raw water and the chemicals mixed in the mixing pipe 120 are discharged to the outside through the discharge pipe 130.
The present invention provides: a mixing pipe 120 having a cleaning hole 121 at the top thereof to enable cleaning of the inside without being detached from the pipe of the existing water treatment system; a chemical injection unit assembly 140 that injects a chemical into the inlet pipe 110 and can be checked at any time during use; and a discharge pipe 130 having a sampling unit assembly 160, the sampling unit assembly 160 measuring a mixing ratio of discharged chemicals to raw water, which is described in detail in the above-described order hereinafter.
The cleaning function of the unpowered in-tube mixing device 100 of the present invention is first described.
Referring to fig. 3, a cleaning hole 121 is formed on the top of the mixing pipe 120. In the case where the mixing apparatus 100 in the unpowered pipe is used normally, the cleaning cover 150 hermetically closes the cleaning hole 121, and in the case where the inside of the mixing apparatus 100 in the unpowered pipe needs to be cleaned, the inside of the mixing pipe 120 can be cleaned by opening only the cleaning hole 121 without detaching the mixing apparatus 100 in the unpowered pipe from the existing water treatment system.
For example, the cleaning cap 150 includes a cap body 151 and a packing member 152. The opening and closing operation of the cleaning lid portion 150 is easily performed by using the bolt and the nut. The open hole flanges 122 having fastening holes formed at certain intervals need to be disposed on the uppermost portions of the cleaning holes 121, wherein the fastening holes of the cleaning cover 150 correspond to the fastening holes of the open hole flanges 122 by forming the fastening holes on the edges of the cleaning cover 150, and the closing operation is performed by fastening through the respective fastening holes using screws and nuts. The opening operation is performed by loosening the bolts and nuts and separating the cleaning cover 150 from the cleaning hole 121.
For better understanding, it is illustrated in the drawings that the cleaning hole 121 formed on the top of the mixing pipe 120 has a protruding rectangular shape, and the cleaning cover 150 has a rectangular shape corresponding to the shape of the cleaning hole 121. However, the position, shape and size of the cleaning hole 121 and the position, shape and size of the cleaning cover 150 may be different according to example embodiments.
Hereinafter, the chemical injection unit assembly 140 and the use unit assembly 160 included in the unpowered in-tube mixing device 100 will be described below.
Fig. 5 is a view illustrating a structure of a chemical injection unit assembly according to an exemplary embodiment of the present invention.
Fig. 6 is a view showing the chemical injection unit assembly from which the chemical injection pipe is detached,
fig. 7 is a view showing the chemical injection unit assembly with the fixing unit detached from the main pipe.
Referring to fig. 5 to 7, it can be seen that the chemical injection unit assembly 140 includes a chemical injection pipe unit 141, a fixing pipe 142, a fixing unit 143, and a valve unit 144.
The fixing pipe 142 is used to insert the chemical injection unit assembly 140 into the inlet pipe 110 and fix the chemical injection unit assembly 140. A portion of the fixing tube 142 opposite to the portion inserted into the inlet tube 110 has a valve unit 144 and a fixing unit 143. The valve unit 144 opens and closes an inner passage of the fixing tube 142, and the fixing unit 143 fixes or releases the chemical injection tube unit 141 inserted into the inside. One end of the chemical injection pipe unit 141 passes through the fixing unit 143 and the inside of the fixing pipe 142 to be inserted into the center of the inlet pipe 110, and transfers the chemical introduced from the other end to the inlet pipe 110. Therefore, the inner diameter of the fixing unit 143 and the inner diameter of the fixing tube 142 need to be larger than the outer diameter of the medicine injection tube 141.
The rotation fixing unit 143-1 is installed at an inlet where the chemical injection pipe 141 of the fixing unit 143 is first inserted. When the rotation fixing unit 143-1 is rotated in one direction, the inner diameter of the fixing unit 143 is increased, and when the rotation fixing unit 143-1 is rotated in the other direction, the inner diameter of the fixing unit 143 is decreased. When the inner diameter of the fixing unit 143 is increased, the chemical injection tube 141 is inserted into the inside of the inlet tube 110, and then when the inner diameter of the fixing unit 143 is decreased, the chemical injection tube 141 is fixed to inject the medicine.
The valve unit 144 has a valve 144-1, and the inner passage of the fixed pipe 142 is opened and closed by the operation of the valve 144-1. The valve 144-1 is opened to insert the chemical injection pipe unit 141 into the inner path of the fixed pipe 142 and to inject the chemical into the inlet pipe 110. In contrast, in case that the chemical injection pipe unit 141 is drawn out from the fixed pipe 142 in order to inspect or clean the chemical injection pipe unit 141, the valve 144-1 is closed to close the inner path of the fixed pipe 142.
Referring to fig. 5 and 6, it can be seen that the chemical injection tube 141 included in the chemical injection unit assembly 140 passes through the fixing unit 143 and the fixing tube 142, and is completely separated from the fixing unit 143 and the fixing tube 142.
The dotted line drawn on the fixed pipe 142 represents a position where the main pipe 142 is to be inserted into the inlet pipe 110 through the chemical injection holes 112 and 113. The chemical injection pipe 141 is introduced into the inside of the inlet pipe 110 through the fixing pipe 142. One of the main concepts of the present invention is that the fixing pipe 142, which has a greater thickness than the chemical injection pipe 141 and is formed of a harder material than the chemical injection pipe 141, can endure the highest possible pressure of raw water flowing in the inlet pipe 110, and only a minimum pressure is applied to the chemical injection pipe 141, which minimizes a portion exposed to the inside of the inlet pipe 110 from the end of the fixing pipe 142.
Referring to a dotted circle in fig. 1, the fixed pipe 142 is inserted to a greater depth of the inlet pipe 110, and the chemical injection pipe 141 is slightly more exposed to the middle of the inlet pipe 110 from the end of the fixed pipe 142.
The unpowered in-pipe mixing device 100 of the present invention is designed in this way: when a chemical is injected into one chemical injection unit assembly 140, another chemical injection unit assembly 140 may be inspected. The inspection of the chemical injection unit assembly 140 is actually to inspect the state of the chemical injection pipe unit 141 included in the chemical injection unit assembly 140. Therefore, after the chemical injection pipe unit 141 to be inspected is separated from the fixed pipe 142 and the fixed unit 143, the valve 144-1 of the valve unit 144 needs to be closed so that the fluid in the unpowered in-pipe mixing device 100 does not leak to the outside through the inner passage of the fixed pipe 142.
The sampling unit assembly 160 has the same configuration and structure as the chemical injection unit assembly 140, so that in fig. 5 to 7, only reference numerals of corresponding units of the chemical injection unit assembly 140 and the sampling unit assembly 160 are shown. Therefore, the description of the operation and function of the sampling unit assembly 160 is replaced by the above description of the chemical injection unit assembly 140 except that the fixing tube 162 included in the sampling unit assembly 160 is not deeply inserted into the inside of the discharge tube 130, but only to a depth close to the inside of the discharge tube 130. The reason for this is that samples can be taken at various positions of the discharge pipe 130 by adjusting the depth and width of the discharge pipe 130.
In the present invention, two chemical injection unit assemblies 140 are inserted so that when one chemical injection unit assembly 140 is cleaned, the other chemical injection unit assembly 140 can be used; and two types of chemicals can be simultaneously injected into the inlet pipe 110. Further, two or more chemical injection unit assemblies 140 may also be installed.
In order to sample where raw water and chemicals are mixed and are to be discharged from the discharge pipe 130 to the outside using the sampling unit assembly 160, the discharge pipe 130 requires at least one sampling hole 132. Sampling is performed by a sampling tube unit 161 included in the sampling unit assembly 160, wherein sampling can be taken at various positions of the discharge tube 130 by adjusting the depth of insertion of the sampling tube unit 161 into the discharge tube 130. The mixing ratio in the total cross section of the discharge tube 130 can be obtained in such a manner that: sampling holes 132 are formed at two positions each in the vertical direction and the horizontal direction of the discharge pipe 130, samples are taken a plurality of times by adjusting the sampling depth and the sampling width of the sampling pipe 161, and the mixture ratio of the taken samples is analyzed.
