Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, and in particular to a wastewater salting device. Background Art

[0002] High-salinity wastewater refers to wastewater with a total salt content of at least 1%, which mainly comes from chemical plants and the collection and processing of oil and natural gas. This wastewater contains a variety of substances (including salt, oil, organic heavy metals and radioactive substances). The production of saline wastewater is extensive and the amount of water is increasing year by year. It is very important to remove the impact of organic pollutants in saline wastewater on the environment.

[0003] A Chinese patent document with authorization announcement number CN213595932U discloses a resin adsorption tank, including a tank body, a water distribution pipe is provided on the upper side of the tank body, a head is provided at the bottom of the tank body, a water outlet pipe is connected to the bottom of the head, a vent valve and a water outlet valve are respectively provided on the left and right sides of the upper part of the water outlet pipe, a first three-way pipe is connected to the upper end of the water outlet pipe, a lower desorption liquid inlet valve and a desorption liquid discharge valve are respectively provided on the left and right sides of the first three-way pipe, a water inlet pipe is provided in the middle of the upper end of the tank body, a pipe mouth valve table is provided on the lower side of the water inlet pipe, a second three-way pipe is connected to the lower end of the water inlet pipe, a water inlet valve and an upper desorption liquid inlet valve are respectively provided on the left and right sides of the second three-way pipe, a resin loading port and a resin unloading port are respectively provided on the upper and lower parts of the left side of the tank body, and an exhaust pipe is provided on the upper side of the tank body.

[0004] When the existing resin adsorption device is in use, the upper layer of resin is in contact with high-concentration sewage, so the upper layer of resin fails first, while the lower layer of resin has not been fully utilized. Since the upper layer of resin fails, it needs to be replaced. If all of them are replaced, it will cause a large waste. Replacing only the upper layer of resin is more troublesome. Summary of the invention

[0005] The invention provides a wastewater salt separation device, aiming to solve the problem of insufficient resin utilization during use of a resin adsorption device in the related art.

[0007] Two spiral leaves, each of which has a through hole, the inner side of the spiral leaves is arranged close to the outer wall of the connecting pipe, the outer side of the spiral leaves is fixedly mounted on the inner wall of the tank body, a spiral channel 1 and a channel 2 are formed between the two spiral leaves, a material distribution cavity is formed between the bottom ends of the two spiral leaves and the inner bottom of the tank body, and the water distributor is located at the bottom of the material distribution cavity;

[0008] A semicircular baffle, a straight edge on one side of the baffle is provided with a material strip extending upward, a water permeable hole is opened on the baffle, the baffle is located above the spiral blade and is coaxially rotatably mounted on the connecting pipe, and the arc surface of the baffle is in contact with the inner wall of the tank body;

[0009] The control component is installed above the baffle and is used to control the rotation of the baffle. When the recoil is working, the baffle blocks the top of the channel. When switching from recoil to adsorption, the control component controls the baffle to rotate multiple times so that the baffle still blocks the top of the channel.

[0010] The spiral blades provide a certain supporting effect on the resin particles, thereby preventing the resin particles at the bottom from being ruptured due to excessive pressure, and when working in recoil, the baffle blocks the top of channel one, and under the recoil of the water flow, the resin particles are dispersed from the top of channel two to the top of the spiral blade, and at the same time, the resin particles in the cloth cavity enter channel two. When switching from recoil to adsorption, gaps appear in the cloth cavity, and the resin particles in channel one and channel two fall, and space appears at the top of channel one and channel two, and then the dispersed resin particles fall into channel two and the baffle, and the control component controls the baffle to rotate multiple times, and the resin particles on the baffle fall, so that the resin particles in channel one and channel two are circulated and fully utilized.

[0011] Preferably, the water distributor is a self-rotating water distributor. When the water distributor discharges water, the water distributor rotates to stir the resin particles in the distribution cavity, and the resin particles in the distribution cavity are evenly dispersed through the self-rotation of the water distributor.

[0012] Preferably, there is a gap between the baffle and the top of the spiral blade to prevent the baffle and the spiral blade from shearing the resin particles and causing the resin particles to break.

[0013] Preferably, the control component includes a rotating sleeve connected to the baffle, the rotating sleeve is equipped with fan blades and a limiting mechanism for limiting the rotating sleeve to rotate counterclockwise, and the rotating sleeve and the connecting pipe are equipped with a positioning mechanism for controlling the number of rotations of the rotating sleeve, so that the baffle is blocked at the top of channel one before the rotating sleeve rotates and after the rotation stops, preventing resin particles in channel one from going out of the top and entering channel two.

[0014] Preferably, the baffle plate is slidably matched with the rotating sleeve in the vertical direction through the guide rod.

[0015] Preferably, the positioning mechanism includes a fixed sleeve fixedly mounted on the connecting pipe, a spiral slide is provided on the fixed sleeve, a rotating sleeve is arranged on the fixed sleeve, a rotating slider which can cooperate with the spiral slide is elastically hinged in the rotating sleeve, when the rotating slider is located at the top or bottom end of the spiral slide, the baffles are blocked at the top end of the channel, the rotating slider and the spiral slide have an engaged state and a disengaged state, when the adsorption is working, the rotating slider is engaged with the spiral slide, so that the rotating slider descends along the spiral slide, and when the recoil is working, the fan blade moves upward, and the rotating slider flips downward and disengages from the spiral slide.

[0016] Preferably, the limiting mechanism comprises a one-way bearing sleeved on the connecting pipe, the inner ring of the one-way bearing is slidably matched with the connecting pipe up and down, and the outer ring of the one-way bearing is fixedly connected with the rotating sleeve.

[0017] Preferably, flexible strips are provided below the straight edges on both sides of the baffle, and the thickness of the flexible strips is not greater than the height of the gap between the baffle and the spiral blade, so as to prevent the resin particles in the channel 1 from coming out of the gap during recoil.

[0018] Beneficial effect: During recoil operation, the baffle blocks the top of channel one, and the resin particles in channel two are not blocked. Under the recoil of water flow, the resin particles are dispersed from the top of channel two to above the spiral blade, and at the same time, the resin particles in the distribution cavity enter channel two. When switching from recoil to adsorption operation, gaps appear in the distribution cavity, and the resin particles in channel one and channel two fall. Space appears at the top of channel one and channel two, and then the dispersed resin particles fall onto channel two and the baffle. The control component controls the baffle to rotate multiple times, and the resin particles on the baffle fall. At the same time, the material strip moves the resin particles into channel one and channel two, so that the top resin particles are flat, so that the baffle still blocks the top of channel one, so that the resin particles at the top of channel two enter channel one, so as to cycle adsorption and recoil, so that the resin particles in channels one and two are circulated, and the resin utilization degree in the tank body tends to be the same.

[0029] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0030] like Figure 1 and Figure 2 As shown, a wastewater salting device comprises a tank body 1, a connecting pipe 2, a water distributor 3, and a sewage pipe 4. The tank body 1 is filled with resin particles. A wastewater inlet 11 is provided at the top of the tank body 1. The sewage pipe 4 is installed on one side of the top of the tank body 1. The connecting pipe 2 is installed on the axis inside the tank body 1. The top of the connecting pipe 2 extends out of the tank body 1 and is connected to a clean water pipe 21 and a recoil pipe 22. The water distributor 3 is installed at the bottom of the connecting pipe 2, and the water distributor 3 is a self-contained water distributor 3. A blocking device is installed at the inner end of the sewage pipe 4. The resin particles pass through the filter screen. When the adsorption is working, the wastewater enters the tank body 1 through the wastewater inlet 11, and the wastewater flows through the resin particles from top to bottom. The resin particles adsorb the salt and other impurities in the wastewater to finally form clean water. The clean water is discharged through the water distributor 3, the connecting pipe 2 and the clean water pipe 21 in turn. After working for a period of time, the clean water pipe 21 and the wastewater inlet 11 are closed, and clean water is introduced into the recoil pipe 22, so that the water outlet of the water distributor 3 recoils the resin particles, and the sewage after recoil is discharged through the sewage pipe 4.

[0031] like Figure 2 and Figure 7As shown, two spiral blades 12, a baffle 13 and a control component are arranged in the tank body 1. The inner sides of the two spiral blades 12 are arranged close to the outer wall of the connecting pipe 2. The outer sides of the spiral blades 12 are fixedly mounted on the inner wall of the tank body 1. A spiral channel 1a and a channel 2 1b are formed between the two spiral blades 12. A distribution cavity is formed between the bottom ends of the two spiral blades 12 and the inner bottom of the tank body 1. The water distributor 3 is located at the bottom of the distribution cavity. Resin particles are filled in the channel 1 1a, the channel 2 1b and the distribution cavity. The spiral blades 12 provide a certain support effect on the resin particles, thereby preventing the resin particles at the bottom from being subjected to excessive pressure and causing rupture. The baffle 13 is semicircular. A material stripping strip 132 extending upward is provided on the straight edge on one side, and a water permeable hole is opened on the baffle 13, the aperture of the water permeable hole is smaller than the particle size of the resin particles, the baffle 13 is located above the spiral blade 12 and is coaxially rotatably installed on the connecting pipe 2, the arc surface of the baffle 13 contacts the inner wall of the tank body 1, and there is a gap between the baffle 13 and the top of the spiral blade 12, and flexible strips 133 with a thickness not greater than the gap height are provided below the straight edges on both sides of the baffle 13, so as to avoid the baffle 13 and the spiral blade 12 shearing the resin particles when rotating, causing the resin particles to be broken, and the control component is installed above the baffle 13 to control the rotation of the baffle 13.

[0032] like Figure 2 , Figure 7 and Figure 8 As shown, during the recoil operation, the baffle 13 blocks the top of channel 1a. Since the resin particles in channel 2 1b are not blocked, under the recoil of the water flow, the resin particles are dispersed from the top of channel 2 1b to the top of the spiral blade 12, and at the same time, the resin particles in the material distribution cavity enter channel 2 1b. When switching from recoil to adsorption operation, gaps appear in the material distribution cavity, and the resin particles in channel 1a and channel 2 1b fall. Spaces appear at the tops of channel 1a and channel 2 1b, and then the dispersed resin particles fall onto channel 2 1b and the baffle 13. The control component controls the baffle 13 to rotate multiple times, and the resin particles on the baffle 13 fall. At the same time, the material shifting bar 132 shifts the resin particles into channel 1a and channel 2 1b, so that the top resin particles are flat, so that the baffle 13 still blocks the top of channel 1a, so that the resin particles at the top of channel 2 1b enter channel 1a, so as to perform adsorption and recoil operations, so that the resin particles in channel 1a and channel 2 1b are circulated and can be fully used.

[0033] like Figure 2-Figure 6As shown, the control assembly includes a rotating sleeve 14 connected to the baffle 13, a positioning mechanism 15 and a limiting mechanism 16. The baffle 13 slides with the rotating sleeve 14 in the vertical direction through a guide rod 131. The rotating sleeve 14 is equipped with a fan blade 141. During adsorption operation, the flow of wastewater causes the fan blade 141 to rotate, thereby causing the rotating sleeve 14 to drive the baffle 13 to rotate. The limiting mechanism 16 is installed on the rotating sleeve 14 to limit the rotating sleeve 14 to rotate only counterclockwise. The positioning mechanism 15 is installed between the rotating sleeve 14 and the connecting pipe 2 to control the number of rotations of the rotating sleeve 14, so that the baffle 13 is blocked at the top of the channel 1a before and after the rotating sleeve 14 stops rotating.

[0034] like Figure 2 , Figure 4 and Figure 6 As shown, the positioning mechanism 15 includes a fixed sleeve 151 and a rotating slider 152 fixedly mounted on the connecting pipe 2. The fixed sleeve 151 is provided with a spiral slideway. The rotating sleeve 14 is sleeved on the fixed sleeve 151. The rotating slider 152 is elastically hinged in the rotating sleeve 14 and cooperates with the spiral slideway. When the rotating slider 152 is located at the top or bottom of the spiral slideway, the baffle 13 is blocked at the top of the channel 1a. The rotating slider 152 and the spiral slideway have an engaged state and a disengaged state. When the adsorption is working, the rotating slider 152 is engaged with the spiral slideway, so that the rotating slider 152 descends along the spiral slideway, causing the resin particles on the baffle 13 to fall. At the same time, the material strip 132 moves the resin particles into the channel 1a and the channel 2 1b, and at the same time smoothes the top resin particles, so that the baffle 13 still blocks the top of the channel 1a, thereby allowing the resin particles at the top of the channel 2 1b to enter the channel 1a.

[0035] like Figure 4 and Figure 6 As shown, the limiting mechanism 16 includes a one-way bearing sleeved on the connecting pipe 2, the inner ring of the one-way bearing slides up and down with the connecting pipe 2, and the outer ring of the one-way bearing is fixedly connected to the rotating sleeve 14. During recoil operation, the outer ring is subjected to a clockwise torque, and the outer ring cannot rotate clockwise relative to the inner ring. Therefore, the fan blades 141 cannot rotate in the opposite direction, and the fan blades 141 move upward, and the rotating slider 152 flips downward and disengages from the spiral slide until it returns to the initial position and engages with the spiral slide again.

[0036] Working principle: When adsorption is in progress, wastewater enters the tank body 1 through the wastewater inlet 11, and the wastewater flows through the resin particles from top to bottom. The resin particles adsorb salt and other impurities in the wastewater, and finally form clean water. The clean water is discharged through the water distributor 3, the connecting pipe 2 and the clean water pipe 21 in sequence. After working for a period of time, the clean water pipe 21 and the wastewater inlet 11 are closed, and clean water is introduced into the recoil pipe 22 for recoil work. The baffle 13 blocks the top of the channel 1a. The resin particles in the channel 2 1b are not blocked. Under the recoil of the water flow, the resin particles are dispersed from the top of the channel 2 1b to the top of the spiral blade 12, and the resin particles in the material distribution cavity enter the channel 2 1b (such as Figure 6 As shown in FIG. 1 ), when switching from recoil to adsorption, a gap appears in the material distribution cavity, the resin particles in channel 1 a and channel 2 1 b fall, and a space appears at the top of channel 1 a and channel 2 1 b, and then the dispersed resin particles fall onto channel 2 1 b and baffle 13 (as shown in FIG. Figure 7 As shown), when switching to adsorption work, the flow of wastewater causes the fan blade 141 to rotate, thereby causing the rotating sleeve 14 to rotate and descend while driving the baffle 13 to rotate until the rotating slider 152 spirally descends to the bottom along the spiral slide. During this process, the resin particles on the baffle 13 fall down, and at the same time, the material strip 132 moves the resin particles into channel 1a and channel 2 1b, so that the top resin particles are flat, so that the baffle 13 still blocks the top of channel 1a, so that the resin particles on the top of channel 2 1b enter channel 1a, so as to perform adsorption and recoil work, so that the resin particles in channel 1a and channel 2 1b are circulated, so that they can be fully used, and at the same time, the spiral blade 12 has a supporting effect on the resin particles, thereby preventing the resin particles at the bottom from being crushed due to excessive pressure.

[0037] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
