[0010] Further description, it also includes a liquid-blocking mechanism for blocking the sewage in the liquid inlet pipe, the liquid-blocking mechanism includes a liquid-blocking plate, a rotating rod, a gear, a positioning frame, a limit rod, a rack and a first spring, the front side of the liquid inlet pipe is rotatably connected with a liquid-blocking plate for blocking the sewage, the front lower side of the right side outside the treatment box is rotatably connected with a rotating rod, the right side of the rotating rod and the right side of the liquid-blocking plate are driven by a synchronous belt assembly, the middle part of the rotating rod is fixedly sleeved with a gear, a positioning frame is fixedly connected to the right front side of the top of the cover plate, the positioning frame is slidably connected to the treatment box, the inner side of the positioning frame is slidably connected with a rack for driving the gear to rotate, the rack is meshed with the gear, a first spring is connected between the top of the rack and the top of the positioning frame, and the left side of the rotating rod is fixedly sleeved with a limit rod for limiting the gear.

[0011] Further description, it also includes an interval feeding mechanism for making the flocculant fall intermittently, and the interval feeding mechanism includes a cam, a limit frame, a second spring, a spring ratchet, a ratchet, a dividing wheel and a guide rod. A dividing wheel for driving the flocculant to fall intermittently is rotatably connected between the lower parts of the front and rear sides of the storage box, and a ratchet is fixedly mounted on the rear side of the dividing wheel. Guide rods are symmetrically fixed to the lower part of the outer rear side surface of the storage box, and a limit frame is slidably mounted between the guide rods on the left and right sides.

[0015] The present invention has significant improvements in that:

[0016] 1. First, discharge the sewage into the treatment box through the liquid inlet pipe, and then pour an appropriate amount of flocculant into the storage box. The flocculant is discharged into the guide pipe and contacts the guide screw. Start the servo motor, and the guide screw rotates to evenly discharge the flocculant into the treatment box and mix it with the sewage. The flocculant treats the impurities soluble in water in the sewage, thereby improving the treatment effect of the sewage.

[0017] 2. Under the action of the liquid blocking mechanism, whenever the cover plate swings downward and does not block the treated sewage, the liquid blocking mechanism can operate to close the liquid inlet pipe, and the sewage stops being discharged into the treatment box. When the sewage treated by the flocculant falls downward, the liquid inlet pipe can be prevented from continuing to discharge the sewage into the treatment box and mixing with the treated sewage, thereby ensuring that all the sewage can be mixed with the flocculant and treated.

[0018] 3. Under the action of the interval feeding mechanism, whenever the servo motor is started, the interval feeding mechanism operates to make the flocculant intermittently discharged into the guide pipe and transported by the guide screw, which can prevent a large amount of flocculant from being discharged into the processing box at one time and causing waste, thereby ensuring that the use effect of the flocculant is maximized.

[0035] The material guiding mechanism 8 includes a servo motor 81, a transmission shaft 82 and a material guiding screw 83, see Figure 3 and Figure 4 As shown, a transmission shaft 82 is rotatably connected between the middle parts of the front and rear sides of the guide pipe 7, and a guide screw 83 is fixedly mounted on the transmission shaft 82. When the guide screw 83 rotates, the guide screw 83 can drive the flocculant to flow. A servo motor 81 is installed on the upper right side of the outer front side of the processing box 1 by welding, and the output shaft of the servo motor 81 and the front side of the transmission shaft 82 are driven by a synchronous belt assembly.

[0036] The liquid discharging mechanism 9 includes an electric push rod 91, a slider 92, a cover plate 93 and a filter assembly 94, see Figure 3 and Figure 5 As shown, a cover plate 93 is rotatably connected to the lower part of the rear side of the treatment box 1, and the cover plate 93 can block the sewage. A slider 92 is slidably connected to the left front side of the cover plate 93. An electric push rod 91 is installed on the middle part of the front side of the left side outside the treatment box 1 by bolt connection. The telescopic rod end of the electric push rod 91 is rotatably connected to the top of the slider 92. A filter component 94 is installed on the lower part of the inner side of the treatment box 1 by bolt connection. When the sewage contacts the filter component 94, the filter component 94 can filter and remove the impurity particles in the sewage.

[0037] First, connect the liquid inlet pipe 3 to the pipe for discharging sewage, and connect the liquid discharge pipe 4 to the pipe for discharging sewage, then pour an appropriate amount of flocculant into the storage box 6, the flocculant in the storage box 6 is discharged into the guide pipe 7, the flocculant contacts the guide screw 83, and then the sewage is discharged into the liquid inlet pipe 3, the sewage in the liquid inlet pipe 3 is discharged into the treatment box 1, and the cover plate 93 blocks the sewage. At this time, start the servo motor 81 to rotate, the servo motor 81 rotates to drive the transmission shaft 82 to rotate, the transmission shaft 82 rotates to drive the guide screw 83 to rotate, the guide screw 83 rotates to drive the flocculant to flow forward, the flocculant flows forward through the guide pipe 7 and is discharged into the treatment box 1 to mix with the sewage, the flocculant also processes the impurities in the sewage, and at the same time, the progress of the sewage treatment can be checked through the observation window 5.

The electric push rod 91 is turned off, and the sewage can be discharged into the treatment box 1 through the inlet pipe 3 again for treatment. In this way, the impurities dissolved in the sewage can be treated by the flocculant, thereby improving the treatment effect of the sewage.

[0038] Example 2

[0039] On the basis of embodiment 1, a liquid blocking mechanism 10 is also included. The liquid blocking mechanism 10 includes a liquid blocking plate 101, a rotating rod 102, a gear 103, a positioning frame 104, a limiting rod 105, a rack 106 and a first spring 107. Figure 6-Figure 9As shown, a liquid blocking plate 101 is rotatably connected to the front side of the liquid inlet pipe 3, and the liquid blocking plate 101 can block the sewage. A rotating rod 102 is rotatably connected to the lower side of the front right side of the treatment box 1. The right side of the rotating rod 102 and the right side of the liquid blocking plate 101 are driven by a synchronous belt assembly. A gear 103 is fixedly sleeved on the middle part of the rotating rod 102, and a positioning frame 104 is installed on the right front side of the top of the cover plate 93 by bolt connection. The positioning frame 104 is slidably connected to the treatment box 1, and a rack 106 is slidably connected to the inner side of the positioning frame 104. The rack 106 meshes with the gear 103. When the rack 106 moves, the rack 106 can drive the gear 103 to rotate. A first spring 107 is connected between the top of the rack 106 and the top of the positioning frame 104. A limiting rod 105 is fixedly sleeved on the left side of the rotating rod 102. When the limiting rod 105 rotates and contacts with the treatment box 1, the limiting rod 105 can limit the gear 103.

[0040] The device also includes an interval feeding mechanism 11, which includes a cam 111, a limit frame 112, a second spring 113, a spring ratchet 114, a ratchet wheel 115, a separation wheel 116 and a guide rod 117. Figure 6 , Fig.10 and Fig.11 As shown, a separating wheel 116 is rotatably connected between the lower parts of the front and rear sides of the storage box 6. When the separating wheel 116 rotates, the separating wheel 116 can drive the flocculant to fall intermittently. A ratchet 115 is fixedly sleeved on the rear side of the separating wheel 116. A guide rod 117 is symmetrically installed on the lower part of the outer rear side surface of the storage box 6 by welding. A limiting frame 112 is slidably sleeved between the guide rods 117 on the left and right sides. A second spring 113 is connected between the upper part of the limiting frame 112 and the lower parts of the guide rods 117 on the left and right sides. A spring ratchet 114 is slidably connected to the upper part of the limiting frame 112, and the spring ratchet 114 is meshed with the ratchet 115. When the spring ratchet 114 moves downward, the spring ratchet 114 can drive the ratchet 115 to rotate. A cam 111 is fixedly sleeved on the rear side of the transmission shaft 82, and the cam 111 corresponds to the limiting frame 112. When the cam 111 rotates, the cam 111 can drive the limiting frame 112 to move upward.

[0041] When the impurities in the sewage are treated by the flocculant, the telescopic rod of the electric push rod 91 is started to extend, and the sliding block 92 drives the cover plate 93 to swing downward. The cover plate 93 swings downward without blocking the sewage, and the sewage flows downward and the impurity particles are filtered by the filter assembly 94. At the same time, the cover plate 93 swings downward and also drives the positioning frame 104 to swing downward. The positioning frame 104 swings downward and drives the rack 106 to swing downward through the first spring 107. The rack 106 swings downward and drives the column gear 103 to reverse. The reversal of the gear 103 drives the rotating rod 102 to reverse. The reversal of the rotating rod 102 drives the liquid blocking plate 101 to reverse through the synchronous belt assembly. The reversal of the liquid blocking plate 101 will The pipe 3 is closed, and the sewage stops being discharged into the treatment box 1 through the liquid inlet pipe 3. At the same time, the reversal of the rotating rod 102 also drives the limiting rod 105 to reverse. When the limiting rod 105 reverses and contacts the treatment box 1, the treatment box 1 limits the limiting rod 105. The limiting rod 105 stops the rotating rod 102 from reversing, and the liquid blocking plate 101 also stops reversing. The rotating rod 102 also stops the gear 103 from reversing, and the gear 103 limits the rack 106. The positioning frame 104 continues to swing downward to compress the first spring 107. When the cover plate 93 swings downward to a suitable position, the electric push rod 91 is closed, and the cover plate 93 stops driving the positioning frame 104 to swing downward. When all the sewage is discharged, the telescopic rod of the electric push rod 91 is shortened and driven by the slider 92 to swing the cover plate 93 upward and reset. The cover plate 93 resets and drives the positioning frame 104 to swing upward. The positioning frame 104 swings upward to stretch and reset the first spring 107, and then the positioning frame 104 drives the rack 106 upward through the first spring 107. The rack 106 moves upward and resets to drive the gear 103 to reset forward. The gear 103 resets forward and drives the rotating rod 102 to reset forward. The rotating rod 102 resets forward and drives the limit rod 105 to reset forward. The rotating rod 102 also drives the liquid blocking plate 101 to reset forward through the synchronous belt assembly. The liquid blocking plate 101 resets without closing the liquid inlet pipe 3, and the sewage can continue to be discharged into the treatment box 1 through the liquid inlet pipe 3 for treatment. In this way, when the sewage treated by the flocculant falls downward, the liquid inlet pipe 3 can be prevented from continuing to discharge the sewage into the treatment box 1 and mixing with the treated sewage to discharge, thereby ensuring that all the sewage can be mixed with the flocculant and treated.

[0042] Initially, the second spring 113 is in a stretched state. When the flocculant is poured into the storage box 6, the flocculant in the storage box 6 contacts the separation wheel 116. Then, when the servo motor 81 is started, the transmission shaft 82 rotates and also drives the cam 111 to rotate. The cam 111 rotates and disengages from the limit frame 112. Due to the action of the second spring 113, the limit frame 112 moves downward and drives the spring ratchet 114 to move downward. The spring ratchet 114 moves downward and drives the ratchet wheel 115 to rotate forward. The ratchet wheel 115 rotates forward and drives the separation wheel 116 to rotate forward. The separation wheel 116 rotates forward and drives the flocculant to rotate forward. When the flocculant rotates forward to the bottom, the flocculant is discharged into the guide pipe 7 through the storage box 6, and the guide screw 83 will evenly discharge the flocculant into the treatment box 1 and mix it with the sewage. When the cam 111 continues to rotate forward so that the convex end contacts the limit frame 112, the cam 111 drives the limit frame 112 to move upward, the second spring 113 is stretched, the limit frame 112 moves upward to drive the spring ratchet 114 to move upward, the ratchet 115 stops rotating forward, the separation wheel 116 stops driving the flocculant to rotate forward to the bottom, the flocculant stops being discharged into the treatment box 1, the ratchet 115 drives the spring ratchet 114 to move a certain distance to the right, the spring ratchet 114 continues to move upward and slides on the ratchet 115, and so on and so forth, so that the flocculant can be discharged into the treatment box 1 at intervals and mixed with the sewage. When the servo motor 81 is turned off, the transmission shaft 82 stops driving the cam 111 to rotate, and the separation wheel 116 stops rotating forward. In this way, a large amount of flocculant can be prevented from being discharged into the treatment box 1 at one time, resulting in waste, thereby ensuring that the use effect of the flocculant is maximized.

[0043] Example 3

[0044] On the basis of the embodiment 1 and the embodiment 2, a stirring frame 12 and a mounting shaft 13 are also included. Fig.12 As shown, an installation shaft 13 is rotatably connected between the lower parts of the front and rear sides of the treatment box 1, and a stirring frame 12 is fixedly mounted on the installation shaft 13. When the stirring frame 12 rotates, the stirring frame 12 can stir the sewage and flocculant. The stirring frame 12 is located in the treatment box 1, and the rear side of the stirring frame 12 and the rear side of the transmission shaft 82 are driven by a synchronous belt assembly.

[0045] Also includes a fixing frame 14 and a filter screen 15, see Fig.12 As shown, a fixing frame 14 is installed on the upper part of the rear side of the treatment box 1 by bolt connection, and a filter screen 15 is fixedly connected to the inner side of the fixing frame 14 along the circumferential direction. When the sewage contacts the filter screen 15, the filter screen 15 can perform preliminary filtration of impurities in the sewage.

[0046] When the transmission shaft 82 rotates, the transmission shaft 82 also drives the installation shaft 13 to rotate through the synchronous belt assembly, and the rotation of the installation shaft 13 drives the stirring frame 12 to rotate. The stirring frame 12 rotates to stir the sewage and the flocculant, so that the flocculant can treat the sewage more fully. When the transmission shaft 82 stops rotating, the transmission shaft 82 stops driving the installation shaft 13 to rotate through the synchronous belt assembly, and the installation shaft 13 stops driving the stirring frame 12 to rotate. In this way, the mixing of sewage and flocculant can be accelerated, thereby improving the treatment effect of the flocculant on sewage.

[0047] When the sewage is discharged into the liquid inlet pipe 3, the sewage in the liquid inlet pipe 3 contacts the filter screen 15, and the filter screen 15 performs preliminary filtering on the impurity particles in the sewage, and the sewage from which the impurity particles are initially filtered continues to be discharged into the treatment box 1 for treatment. In this way, the impurity particles in the sewage can be removed more cleanly.

[0048] Finally, it is necessary to point out that the above content is only used to help understand the technical solution of the present invention and cannot be understood as limiting the scope of protection of the present invention; non-essential improvements and adjustments made by technical personnel in the field of technology based on the above content of the present invention are all within the scope of protection required by the present invention.
