Description

Technical Field

[0001] The invention relates to the technical field of evaporators, in particular to a reverse osmosis saline wastewater evaporator. Background Art

[0002] With the continuous development of industrialization, the discharge of industrial wastewater and domestic water has made the quality of groundwater sources worse and worse, especially saline wastewater. A large number of microorganisms consume oxygen and multiply in the water body, causing the oxygen in the water body to be consumed, resulting in water hypoxia. In the oxygen-deficient water body, organic pollutants are anaerobically decomposed to form a large amount of sulfide, which makes the water body black and smelly. The hydrogen sulfide gas in the black and smelly water causes air pollution.

[0003] The main methods for treating wastewater include ion exchange, membrane concentration and evaporation, among which evaporators are generally required for treatment. Wastewater evaporators are based on the principle of evaporation, concentration and crystallization, aiming at the characteristics of high salt and high concentration of chemical organic wastewater. They use multi-effect reduced pressure evaporation to concentrate and crystallize organic wastewater, separate the salt in the concentrated liquid, and then recover it through a salt collector. The concentrated liquid is dried, recovered or incinerated. The condensed water after evaporation is generally treated through subsequent biochemical treatment to achieve the wastewater discharge standards.

[0004] When the existing reverse osmosis saline wastewater evaporator is filtered through activated carbon, the activated carbon is often placed in a relatively fixed position, resulting in a shorter contact time between the wastewater and the activated carbon, and the filtering effect is poor. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a reverse osmosis saline wastewater evaporator, which solves the problem that when the existing reverse osmosis saline wastewater evaporator is filtered through activated carbon, the contact time between the wastewater and the activated carbon is short, resulting in poor filtration effect due to the relatively fixed placement of the activated carbon.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a reverse osmosis saline wastewater evaporator comprises a box body, a plurality of placement plates are slidably connected to the inner left wall of the box body, filter plates are clamped on the right sides of the plurality of placement plates, a plurality of strip openings are equidistantly opened on the top of the box body, the tops of the plurality of filter plates respectively penetrate the corresponding strip openings, the tops of the plurality of strip openings are fixedly connected with connecting blocks, the tops of the plurality of connecting blocks are fixedly connected with lifting blocks, a hollow box is fixedly connected to the rear side of the box body, a fixing plate is fixedly connected to the middle and lower part of the inner side of the hollow box, a plurality of servo motors are equidistantly fixedly connected to the bottom of the fixing plate, the output ends of the plurality of servo motors penetrate the fixing plate and are fixedly connected with threaded rods, the middle and upper parts of the plurality of threaded rods are respectively threadedly connected to the rear ends of the corresponding lifting blocks, activated carbon is arranged on the top of the placement plate, and a driving mechanism is arranged on the right side of the box body.

[0007] Preferably, the driving mechanism includes a top plate, which is fixedly connected to the top right side of the box body, a plurality of notches are equidistantly provided on the right side of the top plate, a rotating rod is rotatably connected to the inner side of the notch, a bottom plate is rotatably connected to the bottom right side of the box body, a plurality of embedded grooves are equidistantly provided on the top of the bottom plate, a telescopic rod is fixedly connected to the inner right end of the embedded groove, a U-shaped frame is slidably connected to the inner side of the embedded groove, the output ends of the plurality of telescopic rods are respectively fixedly connected to the corresponding U-shaped frames, a connecting rod is rotatably connected to the middle part of the U-shaped frame, and the top ends of the plurality of connecting rods are respectively fixedly connected to the corresponding rotating rods.

[0008] Preferably, the driving mechanism further comprises a pedal, and the front and rear sides of the base plate are both fixedly connected with the pedal.

[0009] Preferably, a plurality of slide grooves are equidistantly provided on the front side of the hollow box, and rear ends of the plurality of lifting blocks are slidably connected to corresponding slide grooves respectively.

[0010] Preferably, a water inlet pipe is connected to the left end of the top front side of the box body, a water outlet is opened at the left bottom of the box body, and a water outlet box is connected to the left side of the water outlet.

[0011] Preferably, a guide plate is fixedly connected to the bottom of the box.

[0012] Preferably, the box body is made of stainless steel.

[0013] Working principle: by placing the activated carbon on the upper side of the placement plate, and engaging the placement plate with the corresponding filter plate, when the wastewater enters the upper side of the first layer of the placement plate from the water inlet pipe, the wastewater contacts the activated carbon and fully penetrates. According to Newton's principle of gravity, the wastewater will gradually penetrate and flow downward, and the contact time between the wastewater and the activated carbon will be increased again in this process. After the wastewater passes through multiple filter plates in turn, the wastewater filtered by the guide plate is guided to the water outlet, thereby improving the wastewater filtration effect. In addition, when the activated carbon needs to be replaced, the servo motor drives the threaded rod to rotate, so that the lifting block slides upward in the slide groove, and the lifting block drives the filter plate to lift and lower. At the same time, the pedal is stepped on, and the output end of the telescopic rod is contracted. The connecting rod drives the U-shaped frame to slide in the embedded groove, and the entire box rotates to the right, so as to add activated carbon to the placement plate through the gap of the strip opening. If the used activated carbon is to be taken out, it is only necessary to swing the filter plate to release the engagement with the placement plate, and the activated carbon falls to the guide plate and flows out from the water outlet, which better meets the use needs.

[0014] The present invention provides a reverse osmosis saline wastewater evaporator. It has the following beneficial effects:

[0015] 1. The present invention places activated carbon on the upper side of the placement plate. According to Newton's principle of gravity, when wastewater enters the upper side of the first layer of placement plate from the water inlet pipe, the wastewater will gradually penetrate and flow downward and fully penetrate. In this process, the contact time between the wastewater and the activated carbon is increased again. After the wastewater passes through multiple filter plates in sequence, the wastewater filtered by the guide plate is guided to the water outlet, thereby improving the wastewater filtration effect.

[0016] 2. The present invention enables the lifting block to slide upward in the slide groove, and the lifting block drives the filter plate to move up and down. At the same time, the pedal is stepped on and the output end of the telescopic rod is contracted. The connecting rod drives the U-shaped frame to slide in the embedded groove, and the whole box body rotates to the right, so that activated carbon is added to the placement plate through the gap of the strip opening, which better meets the use requirements.

[0024] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] Example:

[0026] Please see attached Figure 1 - Attachment Figure 6 The embodiment of the present invention provides a reverse osmosis saline wastewater evaporator, comprising a box body 1, a plurality of placement plates 2 are slidably connected to the inner left wall of the box body 1, a filter plate 3 is clamped on the right side of the plurality of placement plates 2, a plurality of strip openings 16 are equidistantly opened on the top of the box body 1, the tops of the plurality of filter plates 3 respectively penetrate the corresponding strip openings 16, the tops of the plurality of strip openings 16 are fixedly connected to connection blocks 5, the tops of the plurality of connection blocks 5 are fixedly connected to lifting blocks 6, a hollow box 9 is fixedly connected to the rear side of the box body 1, and the inner A fixed plate 10 is fixedly connected to the middle and lower part of the side, and a plurality of servo motors 11 are fixedly connected to the bottom of the fixed plate 10 at equal intervals. The output ends of the plurality of servo motors 11 all penetrate the fixed plate 10 and are fixedly connected to threaded rods 12. The middle and upper parts of the plurality of threaded rods 12 are respectively threadedly connected to the rear ends of the corresponding lifting blocks 6. Activated carbon is arranged on the top of the placement plate 2, and a driving mechanism 15 is arranged on the right side of the box body 1. A plurality of slide grooves 13 are equidistantly opened on the front side of the hollow box 9, and the rear ends of the plurality of lifting blocks 6 are respectively slidably connected to the corresponding slide grooves 13.

[0027] Specifically, by placing activated carbon on the upper side of the placement plate 2, and engaging the placement plate 2 with the corresponding filter plate 3, when the wastewater enters the upper side of the first layer of the placement plate 2 from the water inlet pipe 7, the wastewater contacts the activated carbon and fully penetrates. According to Newton's principle of gravity, the wastewater will gradually penetrate downward, and the contact time between the wastewater and the activated carbon will be increased again in this process. After the wastewater passes through multiple filter plates 3 in sequence, the filtered wastewater is guided to the water outlet 14 by the guide plate 4, thereby improving the wastewater filtration effect. The activated carbon is placed on the upper side of the placement plate 2, so that the wastewater can contact the activated carbon when entering the first layer of the placement plate 2. Activated carbon has a very strong adsorption capacity and can effectively remove harmful substances in wastewater. In addition, the placement plate 2 is tightly engaged with the corresponding filter plate 3, ensuring that the wastewater can fully contact the activated carbon when passing through, thereby improving the filtration effect. According to Newton's principle of gravity, the wastewater will gradually penetrate downward along the placement plate 2. In this process, the contact time between the wastewater and the activated carbon is extended, so that the harmful substances in the wastewater are more thoroughly adsorbed by the activated carbon. The wastewater passes through multiple filter plates 3 in sequence to further remove residual harmful substances. In this process, the quality of the wastewater is gradually improved after being filtered by each filter plate 3. The filtered wastewater is guided to the outlet 14 through the guide plate 4. In this way, the wastewater that has been filtered multiple times can meet the discharge standards, reducing the impact of the wastewater on the environment. In summary, this method of filtering wastewater using activated carbon effectively improves the wastewater filtering effect by increasing the contact time between the wastewater and the activated carbon and the number of filter layers.

[0028] The driving mechanism 15 includes a top plate 1501, which is fixedly connected to the top right side of the box body 1, and a plurality of notches 1508 are equidistantly provided on the right side of the top plate 1501, and a rotating rod 1502 is rotatably connected to the inner side of the notch 1508, and a bottom plate 1503 is rotatably connected to the bottom right side of the box body 1, and a plurality of embedded grooves 1504 are equidistantly provided on the top of the bottom plate 1503, and a telescopic rod 1505 is fixedly connected to the right end of the inner side of the embedded groove 1504, and a U-shaped frame 1506 is slidably connected to the inner side of the embedded groove 1504, and the output ends of the plurality of telescopic rods 1505 are respectively fixedly connected to the corresponding U-shaped frames 1506, and a connecting rod 1507 is rotatably connected to the middle part of the U-shaped frame 1506, and the top ends of the plurality of connecting rods 1507 are respectively fixedly connected to the corresponding rotating rods 1502; the driving mechanism 15 also includes a pedal 1509, and the front and rear sides of the bottom plate 1503 are both fixedly connected to the pedal 1509;

[0029] Specifically, when the activated carbon needs to be replaced, the servo motor 11 drives the threaded rod 12 to rotate, so that the lifting block 6 slides upward in the chute 13, and the lifting block 6 drives the filter plate 3 to lift and lower, and at the same time, the pedal 1509 is stepped on, and the output end of the telescopic rod 1505 is contracted, and the connecting rod 1507 drives the U-shaped frame 1506 to slide in the embedded groove 1504, and the entire box body 1 rotates to the right, so that the activated carbon is added to the placement plate 2 through the gap of the strip opening 16. If the used activated carbon is to be taken out, it is only necessary to swing the filter plate 3 to release the engagement with the placement plate 2, and the activated carbon falls to the guide plate 4 and flows out from the water outlet 14, which better meets the use requirements. When the activated carbon reaches its service life and needs to be replaced, the servo motor 11 is started, which will drive the threaded rod 12 to rotate. This action causes the lifting block 6 to slide upward in the chute 13. In this process, the lifting block 6 will drive the filter plate 3 to lift and lower. At the same time, the pedal 1509 also needs to be stepped on so that it can be retracted in coordination with the output end of the telescopic rod 1505. The connecting rod 1507 drives the U-shaped frame 1506 to slide in the embedded groove 1504. This series of actions will cause the entire box 1 to rotate to the right. At this time, the activated carbon can be added to the placement plate 2 through the gap of the strip opening 16. This process is very convenient, and the user can complete the adding operation without touching the activated carbon. If you need to remove the used activated carbon, just gently swing the filter plate 3 to release it from the placement plate 2. The activated carbon will fall to the guide plate 4 and flow out of the water outlet 14. This process is simple and easy to operate, and can ensure that the activated carbon is smoothly removed. The design of this activated carbon replacement mechanism fully considers the user's usage needs and safety. It not only makes the replacement of activated carbon more convenient, but also ensures the smooth progress of the entire process.

[0030] The left end of the top front side of the box body 1 is connected with a water inlet pipe 7, and the left bottom of the box body 1 is provided with a water outlet 14, and the left side of the water outlet 14 is connected with a water outlet box 8; the bottom of the box body 1 is fixedly connected with a guide plate 4;

[0031] Specifically, the wastewater is conveniently transported into the water tank 1 through the water inlet pipe 7, and the wastewater after filtration is conveniently discharged in conjunction with the water outlet 14 and the water outlet box 8, wherein the guide plate 4 plays a drainage role, and the core part of the equipment is the water tank 1, which is responsible for storing wastewater. The water tank 1 is made of high-quality materials, has good corrosion resistance and pressure resistance, and ensures the safe and stable operation of the equipment. Inside the water tank 1, there are water outlets 14 and water outlet boxes 8, which are convenient for discharging the treated wastewater. The design of the water outlet 14 and the water outlet box 8 fully considers the principle of humanization, making the operation easier. Secondly, the water inlet pipe 7 plays the role of transporting wastewater to the water tank 1. The water inlet pipe 7 is made of pressure-resistant and wear-resistant materials, which ensures the safety and stability of the wastewater during transportation. At the same time, the design of the water inlet pipe 7 should take into account the installation position of the wastewater treatment equipment to ensure that it is easy to install and maintain. In the wastewater treatment process, the guide plate 4 plays a vital role. It is located between the water outlet 14 and the water outlet box 8 and plays a drainage role. The design of the guide plate 4 fully considers the direction and speed of the water flow, ensuring that the wastewater can flow smoothly between the water outlet 14 and the water outlet box 8, thereby improving the wastewater treatment effect. In addition, the guide plate can also prevent wastewater from splashing out and keep the surrounding environment clean. In summary, this wastewater treatment equipment realizes the filtration treatment and discharge of wastewater through the synergistic effect of components such as the water tank 1, the water inlet pipe 7, the water outlet 14 and the guide plate 4. The equipment has a simple structure and is easy to operate, which can not only meet environmental protection requirements, but also realize resource recycling.

[0033] Specifically, by using stainless steel material for the box body 1, the rigidity and strength of the entire device are increased, making the entire device less likely to be damaged by collision.
