DETAILED DESCRIPTION
[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0029] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0030] See also Figure 1-Figure 10 The present invention provides a technical solution: a salt-containing wastewater treatment device in the production of meta-cresol, comprising an evaporating bucket 1, a magnet frame 12 is welded on the top inner wall of the evaporating bucket 1, a load-bearing plate 3 is slidably inserted in the evaporating bucket 1, a slide bar 31 is welded on the outer wall of the load-bearing plate 3, the slide bar 31 is slidably inserted on the outer wall of the magnet frame 12, a spring 32 is welded between the top outer wall of the slide bar 31 and the outer wall of the magnet frame 12, a blanking plate 4 is rotatably sleeved on the outer wall of the slide bar 31, the blanking plate 4 is tightly fitted with the load-bearing plate 3, a stirring blade 5 is rotatably sleeved on the outer wall of the slide bar 31, and the stirring blade 5 is tightly fitted with the blanking plate 4, a rotating coil spring 51 is welded between the inner ring wall of the stirring blade 5 and the outer wall of the sliding rod 31, a capstan 52 is welded on the inner ring wall of the stirring blade 5, the capstan 52 is sleeved on the outer wall of the sliding rod 31, a rope 521 is wound on the outer wall of the capstan 52, a wire opening 311 is provided on the outer wall of the sliding rod 31, one end of the rope 521 away from the capstan 52 passes through the wire opening 311 and is fixed on the magnet frame 12, a receiving groove 121 is provided on the outer wall of the magnet frame 12, the receiving groove 121 is adapted to the stirring blade 5, and both ends of the stirring blade 5 abut against the inner wall of the evaporating bucket 1.
[0031] The slide bar 31 can only slide relative to the magnet frame 12 and cannot rotate, so that the wire port 311 is fixed relative to the stirring blade 5. When the load-bearing plate 3 drives the slide bar 31 to move downward, the slide bar 31 drives the stirring blade 5 to move downward, so that the rope 1 is stretched 521, so that the rope 521 pulls the capstan 52 to drive the stirring blade 5 to rotate, thereby achieving a stirring effect.
[0032] In the initial state, under the action of the rotating coil spring 51, the stirring blade 5 is aligned with the receiving groove 121, under the action of the spring 32, the load-bearing plate 3 is located at the top of the evaporating bucket 1, the stirring blade 5 is inserted into the receiving groove 121, the rope 521 is wound on the winch 52, and the part of the rope 521 located in the receiving groove 121 is in a relaxed state.
[0033] The above content is further elaborated: during operation, wastewater enters the evaporating bucket 1 and falls on the load-bearing plate 3. The weight of the wastewater overcomes the elastic force of the spring 32, so that the load-bearing plate 3 moves downward, and the load-bearing plate 3 drives the unloading plate 4 and the stirring blade 5 to move downward. As the stirring blade 5 slides out of the receiving groove 121, the rope 521 is gradually tightened, so that when the stirring blade 5 slides out of the receiving groove 121, the rope 521 starts to pull the capstan 52 to rotate, and the capstan 52 drives the stirring blade 5 to rotate and compresses the rotating coil spring 51, so as to achieve the stirring effect by using the wastewater's own gravity as the driving force, which is more energy-saving and environmentally friendly.
[0034] Specifically, a rotating seat 2 is rotatably plugged into the top outer wall of the evaporating bucket 1, a motor 21 is welded on the outer wall of the rotating seat 2, a gear 22 is welded on the main shaft of the motor 21, meshing teeth 11 are welded on the top outer wall of the evaporating bucket 1, the meshing teeth 11 and the gear 22 are meshed with each other, a condenser 23 is fixed on the top outer wall of the rotating seat 2, the focus of the condenser 23 is located in the evaporating bucket 1, and a photovoltaic panel 24 is fixed on the top outer wall of the rotating seat 2, and the photovoltaic panel 24 can provide power for the motor 21.
[0035] The above content is further elaborated: sunlight is focused into the evaporation bucket 1 through the condenser 23, so that the waste water in the evaporation bucket 1 is heated and evaporated, and no electric heating is required, which is more energy-saving and environmentally friendly. The photovoltaic panel 24 provides electricity to the motor 21, and the motor 21 drives the gear 22 to rotate. Under the meshing action of the meshing teeth 11 and the gear 22, the direction of the condenser 23 can be adjusted to improve the utilization rate of sunlight. For the evaporated water, condensation equipment can be added as needed to recover it.
[0036] Specifically, an avoidance groove 33 is provided on the outer wall of the load-bearing plate 3, and a discharge port 42 is provided on the outer wall of the discharge plate 4, and the discharge port 42 is adapted to the avoidance groove 33. A reset coil spring 41 is welded between the outer wall of the discharge plate 4 and the outer wall of the slide rod 31, and an inclined block 6 is slidably inserted on the outer wall of the discharge plate 4, and the inclined block 6 is adapted to the stirring blade 5. The inclined block 6 is located in the avoidance groove 33, and a spring 2 61 is welded between the outer wall of the inclined block 6 and the outer wall of the discharge plate 4, and a clamping tooth 62 is welded on the outer wall of the inclined block 6. A mounting seat 34 is welded on the outer wall of the lower side of the load-bearing plate 3, and a clamping block 7 is welded on the outer wall of the mounting seat 34, and the clamping block 7 is adapted to the clamping tooth 62, and the inclined block 6 and the magnet frame 12 repel each other with the same poles.
[0037] In the initial state, under the action of the reset coil spring 41, the discharge port 42 and the avoidance groove 33 are offset from each other, so that the waste water can be intercepted above the load-bearing plate 3. Under the action of the magnet frame 12, the inclined block 6 is pushed into the discharge plate 4 by the magnetic force.
[0038] The above content is further elaborated: during operation, since the wastewater presses down the load-bearing plate 3, the stirring blade 5 rotates during the downward movement. For the convenience of subsequent explanation, the rotation of this process is defined as positive rotation. As the inclined block 6 moves away from the magnet frame 12, the spring 2 61 gradually pushes the inclined block 6 out of the unloading plate 4. When the stirring blade 5 rotates forward, it can push the inclined block 6 into the unloading plate 4 along the inclined surface of the inclined block 6 to avoid the position. When the gravity of the wastewater is balanced with the spring 1 32, the load-bearing plate 3 stops moving downward, and the stirring blade 5 does not move. The stirring blade 5 is rotated again. When the evaporation is finished, the water evaporates and only the crystallized salt remains in the evaporation bucket 1. The weight of the crystallized salt is not enough to balance the elastic force of the spring 32, so that under the action of the spring 32, the load-bearing plate 3 drives the unloading plate 4 and the stirring blade 5 to move upward. Under the action of the rotating coil spring 51, the stirring blade 5 drives the capstan 52 to reverse and rewind the rope 521. During the upward and reverse movement of the stirring blade 5, the crystallized salt attached to the inner wall of the evaporation bucket 1 and the unloading plate 4 can be scraped off. At the same time, the stirring blade 5 is obliquely moved during the reverse movement. The block 6 intercepts, so that the stirring blade 5 drives the unloading plate 4 to rotate through the inclined block 6. When the unloading plate 4 drives the unloading port 42 to align with the avoidance groove 33, the inclined block 6 is just engaged with the clamping block 7. At the same time, the clamping block 7 pushes the inclined block 6 downward through the inclined surface, so that the inclined block 6 retracts into the unloading plate 4 again, so that the unloading plate 4 no longer rotates with the stirring blade 5, and the unloading port 42 and the avoidance groove 33 remain aligned. As the stirring blade 5 continues to rotate, the crystallized salt will be pushed into the unloading port 42 by the stirring blade 5 to complete the unloading. When the load-bearing plate 3 returns to the top of the evaporating bucket 1 again, under the action of the rotating coil spring 51, the stirring blade 5 rotates to be aligned with the receiving groove 121 and is inserted into the receiving groove 121, so that the crystallized salt attached to the outer wall of the stirring blade 5 is scraped off. At the same time, the magnetic force of the magnet frame 12 pushes the inclined block 6 downward, so that the inclined block 6 is separated from the blocking block 7, so that under the action of the reset coil spring 41, the unloading plate 4 rotates and resets, and then the unloading port 42 and the avoidance groove 33 are reset relative to each other, which is convenient for subsequent waste liquid treatment.
[0039] Specifically, a material storage barrel 13 is welded on the outer wall of the evaporating bucket 1, and a water valve 14 is installed at the connection between the material storage barrel 13 and the evaporating bucket 1. A load-bearing plate 8 is slidably inserted in the material storage barrel 13, and a slide bar 81 is welded on the lower outer wall of the load-bearing plate 8. The slide bar 81 observes the bottom of the material storage barrel 13, and a spring 82 is welded between the end wall of the slide bar 81 and the outer wall of the material storage barrel 13. A connecting rod 83 is rotatably inserted on the end wall of the slide bar 81, and an L-shaped limit block 84 is rotatably inserted on the outer wall of the connecting rod 83 away from the slide bar 81. The short side of the limit block 84 is slidably inserted on the inner wall of the evaporating bucket 1, and the limit block 84 is adapted to the load-bearing plate 3.
[0040] The storage barrel 13 can make the weight of each batch of wastewater greater than the elastic force of the spring 1 32, ensuring that the wastewater can smoothly press the load-bearing plate 1 3 downward.
[0041] In the initial state, the limit block 84 is pushed into the inner wall of the evaporating bucket 1 by the load-bearing plate 1 .
[0042] The above content is further elaborated: during operation, when the load-bearing plate 3 is pressed down by the wastewater to below the limit block 84, under the joint action of the spring three 82 and the connecting rod 83, the limit block 84 slides out from the inner wall of the evaporating bucket 1, thereby intercepting the load-bearing plate 3 to prevent the load-bearing plate 3 from gradually moving up and resetting as the wastewater is evaporated. When the evaporation is completed, the subsequent wastewater is added to the storage barrel 13, so that the wastewater presses the load-bearing plate 2 8 to move downward, so that under the joint action of the spring three 82 and the connecting rod 83, the limit block 84 is again received into the inner wall of the evaporating bucket 1, and then under the action of the spring 1 32, the load-bearing plate 3 can move up and reset, realizing the discharge process of the crystallized salt. After the discharge of the crystallized salt is completed, the water valve 14 is opened, and the wastewater in the storage barrel 13 enters the evaporating bucket 1 for a new round of evaporation treatment.
[0043] The working principle and use process of the present invention are as follows: when working, waste water is input into the storage barrel 13, the water valve 14 is opened, and the waste water enters the evaporation bucket 1 and then the water valve 14 is closed. The weight of the waste water overcomes the elastic force of the spring 32, so that the load-bearing plate 3 moves downward, and the load-bearing plate 3 drives the unloading plate 4 and the stirring blade 5 to move downward. As the stirring blade 5 gradually moves away from the magnet frame 12, the rope 521 is gradually tightened, so that when the stirring blade 5 slides out of the storage groove 121, the rope 521 starts to pull the winch 52 to drive the stirring blade 5 to rotate, so as to realize the self-gravity of the waste water. The condenser 23 is used as the driving force to achieve the stirring effect, which is more energy-saving and environmentally friendly. The sunlight is focused into the evaporating bucket 1 through the condenser 23, so that the wastewater in the evaporating bucket 1 is heated and evaporated, and no electric heating is required, which further improves the energy-saving and environmental protection effect. When the evaporation is completed, the water evaporates, and only crystallized salt is left in the evaporating bucket 1. The weight of the crystallized salt is not enough to balance the elastic force of the spring 1 32. The subsequent wastewater is added to the storage barrel 13, so that the wastewater presses the load-bearing plate 2 8 to move downward, so that under the joint action of the spring 3 82 and the connecting rod 83, the limit block 84 is retracted into the evaporating bucket 1 to press the load-bearing plate The load-bearing plate 3 is avoided, and then under the action of the spring 32, the load-bearing plate 3 can move up and reset, and the load-bearing plate 3 drives the unloading plate 4 and the stirring blade 5 to move up. Under the action of the rotating coil spring 51, the stirring blade 5 drives the capstan 52 to reverse and rewind the rope 521. During the upward and reverse movement of the stirring blade 5, the crystallized salt attached to the inner wall of the evaporating bucket 1 and the unloading plate 4 can be scraped off. At the same time, during the reverse movement of the stirring blade 5, the unloading plate 4 is driven to rotate through the inclined block 6, so that the unloading plate 4 drives the unloading port 42 to align with the avoidance groove 33. As the stirring blade 5 continues to rotate, the crystallized salt The salt will be pushed into the discharge port 42 by the stirring blade 5 to complete the discharge of the crystallized salt. When the load-bearing plate 3 returns to the top of the evaporating bucket 1 again, the stirring blade 5 is inserted into the receiving groove 121, so that the crystallized salt attached to the outer wall of the stirring blade 5 is scraped off. At the same time, the magnetic force of the magnet frame 12 pushes the inclined block 6 to move downward, so that the inclined block 6 is separated from the blocking block 7, so that under the action of the reset coil spring 41, the discharge plate 4 rotates and resets, and then the discharge port 42 and the avoidance groove 33 are reset to each other, and the subsequent waste water is added to the storage barrel 13, and the water valve 14 is opened to carry out a new round of evaporation treatment.
