Description

Full frequency conversion and PLC control secondary pressurized water supply equipment TECHNICAL FIELD

[0001] The present application relates to the technical field of water supply equipment, in particular to a full frequency conversion and PLC control secondary pressurized water supply equipment. BACKGROUND

[0002] Secondary pressurized water supply refers to increasing water pressure by air pressure and other methods in addition to gravity to send water to a higher water level, which can break the traditional high water tower mode and directly supply water from low to high, and is more suitable for water supply of high-rise buildings. A self-adaptive stable pressure type secondary pressurized water supply equipment is currently used.

[0003] Most of the existing secondary water supply equipment do not have a water treatment mechanism, which not only affects the water supply quality, but also causes damage to the booster pump body when unfiltered suspended solids in the water pass through the booster pump, affecting the service life of the booster pump. It is also easy to form scale and other impurities in the water tank, thereby affecting the normal use of the secondary pressurized water supply equipment, and some suspended solids and heavy metal ions and other harmful substances in the water will cause corrosion phenomenon to the inner wall of the cylindrical pipe, thereby affecting the service life of the pipeline.

[0004] SUMMARY

[0005] The purpose of the present application is to provide a full frequency conversion and PLC control secondary pressurized water supply equipment to solve the problems raised in the background art.

[0006] In order to solve the above technical problems, the present application provides the following technical scheme:

[0007] A full frequency conversion and PLC control secondary pressurized water supply equipment, comprising: a water storage tank, a pressurized pump is arranged in the water storage tank, further comprising: a water treatment equipment, the water treatment equipment is communicated with the water storage tank through a pipeline, the water treatment equipment comprises: a machine body, a sedimentation chamber is arranged at the top of the machine body, a power chamber is arranged at the bottom of the sedimentation chamber, a transition device is arranged in the sedimentation chamber, the transition device comprises: a reciprocating barrel, the reciprocating barrel is slidably connected with the sedimentation chamber, a condensation device is arranged on the side of the power chamber away from the sedimentation chamber, the condensation device comprises: a treatment chamber.

[0008] The wastewater is transported into the machine through the pipeline, and then enters the sedimentation chamber. The wastewater is subjected to sedimentation treatment in the sedimentation chamber. When the wastewater is stratified, the controller controls the transition device to start. The surface layer of the wastewater enters the reciprocating barrel. The reciprocating barrel reciprocates in the sedimentation chamber, so that the stratified wastewater is transported into the treatment chamber through the reciprocating barrel. When the wastewater enters the treatment chamber, the controller controls the coagulation device to start. The coagulation device treats the wastewater in the treatment chamber, so that the suspended solids in the wastewater are coagulated into groups, and then the suspended solids and water are separated to achieve the effect of treating the wastewater. The treated wastewater is transported into the water storage tank through the pipeline.

[0009] When water supply is needed, the controller controls the pressurizing pump in the water storage tank to start. The pressurizing pump transports the water in the water storage tank after pressurization. The worker controls the power of the pressurizing pump through the PLC controller according to the required water quantity, so as to realize full-band power water supply.

[0010] Preferably, the side of the reciprocating barrel close to the treatment chamber is provided with an extension pipe, the extension pipe is communicated with the reciprocating barrel, the bottom of the reciprocating barrel is symmetrically provided with a fixed plate, the side of the fixed plate away from the reciprocating barrel is provided with an impact block, and the reciprocating barrel is provided with a permeation plate.

[0011] Preferably, the side of the fixed plate close to the power chamber is provided with a sliding rod, the sidewall of the power chamber is provided with a sliding groove, the sliding rod is slidably connected with the sliding groove, the power chamber is provided with a motor, the driving shaft of the motor is provided with a transmission shaft, the sidewall of the transmission shaft is provided with a groove, and the sliding rod extends to the groove and is slidably connected with the groove.

[0012] Preferably, one end of the extension pipe extends to the side close to the treatment chamber, one end of the extension pipe in the treatment chamber is provided with a pressing strip, the pressing strip is provided with a water flow groove, and the two sides of the pressing strip are provided with a plurality of water flow openings. The plurality of water flow openings are equidistantly arranged along the side edges of the water flow groove.

[0013] After the wastewater is stratified in the sedimentation chamber, the controller controls the motor in the power chamber to start. The driving shaft of the motor drives the transmission shaft to rotate. When the transmission shaft rotates, the groove rotates, and the sliding rod moves. The sliding rod moves along the sliding groove to the side close to the treatment chamber. In the process of moving, the sliding rod drives the fixed plate to move, and the fixed plate drives the impact block to move to the side close to the treatment chamber. When the impact block moves, it impacts the top of the treatment chamber. The vibration generated by the impact is transmitted to the sedimentation chamber, which accelerates the precipitation of impurities in the wastewater, thereby improving the stratification efficiency of the wastewater.

[0014] When the fixed plate moves, the fixed plate drives the reciprocating barrel to move, and the reciprocating barrel drives the permeation plate to move. When the sliding rod moves to the bottom end of the sliding groove, the surface of the reciprocating barrel is just below the surface of the wastewater, and the surface water of the wastewater is immediately transported into the reciprocating barrel. In the process of transporting the wastewater, the controller controls the motor to reverse, and then the transmission shaft reverses to drive the sliding rod to rise. The sliding rod drives the fixed plate to move to the side close to the settling chamber, that is, the fixed plate drives the reciprocating barrel to rise. The height of the upper surface of the reciprocating barrel is immediately higher than the height of the wastewater surface, and the wastewater in the reciprocating barrel is transported to the side close to the extension pipe through the permeation plate.

[0015] The reciprocating barrel transports the surface water of the wastewater under the action of the reciprocating movement of the sliding rod, and the sliding rod drives the impact block to reciprocally impact the treatment chamber when reciprocating. The vibration generated by the impact block is transmitted to the treatment chamber and the settling chamber through the machine body, so that the wastewater in the settling chamber speeds up the settling speed under the action of the vibration wave, reduces the settling time of the impurities, and improves the efficiency of the wastewater impurity layering.

[0016] The wastewater transported into the extension pipe is transported into the water flow tank through the extension pipe, and then flows into the water flow inlet through the water flow tank, and finally is sprayed out of the two cylindrical pipes through the water flow inlet.

[0017] Preferably, the treatment chamber is composed of two cylindrical pipes, a delivery chamber is arranged in the inner wall of the treatment chamber, an air bag is arranged in the delivery chamber, the air bag extends to the side of the delivery chamber close to the middle of the treatment chamber, the air bag is in sliding connection with the treatment chamber, a plurality of output ports are arranged on the side of the air bag close to the treatment chamber, the plurality of output ports are arranged around the axis of the cylindrical pipe, and the side of the air bag extending to the treatment chamber is in contact with the lower surface of the extrusion strip.

[0018] Preferably, one side of the cylindrical pipe is provided with an extrusion pipe, the extrusion pipe is composed of a tapered pipe and a filter pipe, the tapered pipe is in communication with the cylindrical pipe, a plurality of filter holes are arranged on the side of the tapered pipe away from the cylindrical pipe, the plurality of filter holes are arranged around the axis of the tapered pipe, an impurity chamber is arranged outside the machine body, the end of the tapered pipe away from the filter pipe is in communication with the impurity chamber, and a water outlet is arranged at the bottom of the filter pipe and is in communication with a water storage tank through a pipeline.

[0019] Preferably, a rotating shaft is arranged in the cylindrical pipe, the rotating shaft extends to the side close to the extrusion pipe, an electromagnetic coil is arranged in the cylindrical pipe, a magnetic conductor is arranged in the rotating shaft, a spiral plate is arranged on the shaft arm of the rotating shaft, and the number of spiral turns of the spiral plate located in the cylindrical pipe is less than the number of spiral turns of the spiral plate located in the extrusion pipe.

[0020] Preferably, the spiral plate is made of aluminum or zinc, an electrically conductive ring is arranged at the end of the rotating shaft away from the extrusion pipe, the electrically conductive ring is in sliding connection with the spiral plate, and the electrically conductive ring is electrically connected with an external power supply.

[0021] In the process of wastewater flowing into the cylindrical tube through the water outlet, the reciprocating barrel moves back and forth along the axis. In the process of the movement of the reciprocating barrel, the reciprocating barrel drives the extension tube to move. In the process of the movement of the extension tube, the extension tube drives the extrusion bar to the side close to the air bag. When the extrusion bar moves, it squeezes the air bag, and the air bag moves to the side close to the conveying chamber. At this time, the pressure in the air bag is greater than the pressure in the treatment chamber. The coagulant in the air bag is then transported through the output port, and the coagulant is ejected through several output ports. Since the several output ports are arranged around the axis of the cylindrical tube, several streams of coagulant move from the edge of the cylindrical tube to the center of the cylindrical tube, thereby increasing the contact area between the wastewater and the coagulant; at the same time, the vibration wave generated by the impact of the impact block is transmitted to the cylindrical tube through the treatment chamber, and the vibration wave is transmitted to the wastewater in the cylindrical tube, accelerating the movement between the wastewater and the coagulant. The coagulant moves from the periphery to the center and cooperates with the vibration wave, further increasing the contact area between the wastewater and the coagulant, and improving the coagulation efficiency of suspended matter in the wastewater, thereby improving the separation efficiency of the wastewater and the suspended matter;

[0022] During the mixing process of the coagulant and water, the controller controls the electromagnetic coil in the cylindrical tube to be energized. When the electromagnetic coil is energized, a magnetic force is generated, which attracts the rotating shaft to rotate. When the rotating shaft rotates, the spiral plate is driven to rotate. During the rotation of the spiral plate, the spiral plate drives the wastewater and coagulant to stir, causing the wastewater and coagulant to rotate around the axis of the rotating shaft, thereby improving the efficiency of mixing the wastewater and coagulant. At the same time, the spiral plate moves the wastewater and coagulated suspended matter in the cylindrical tube to the side close to the extrusion tube. The wastewater and coagulated suspended matter first enter the conical tube. Since the number of spiral turns of the spiral plate located in the cylindrical tube is less than the number of spiral turns of the spiral plate located in the extrusion tube, the wastewater and coagulated suspended matter are squeezed and compressed in the conical tube. The wastewater is transported to the side close to the filter tube through the filter holes on the conical tube, while the coagulated suspended matter gathers at the end of the conical tube away from the cylindrical tube. The filtered wastewater is transported to the water outlet through the filter tube and finally transported to the water storage tank through the water outlet, while the coagulated suspended matter is transported to the impurity chamber through the pipeline.

[0024] Compared with the prior art, the beneficial effects achieved by the present application are:

[0025] 1. The reciprocating barrel transports the surface water of the wastewater under the action of the reciprocating movement of the sliding rod, and the sliding rod reciprocally moves to reciprocally impact the impact block, the vibration generated by the impact block is transmitted to the treatment cavity and the sedimentation cavity through the machine body, so that the wastewater in the sedimentation cavity is accelerated in the vibration wave, the impurity sedimentation time is reduced, and the wastewater impurity layering efficiency is improved.

[0047] The working principle of the present application is as follows:

[0048] After the wastewater is stratified in the sedimentation cavity 11, the controller controls the motor in the power cavity 12 to start, the driving shaft of the motor drives the transmission shaft 13 to rotate, the transmission shaft 13 drives the groove to rotate when rotating, the groove drives the sliding rod 24 to move when rotating, the sliding rod 24 moves along the sliding groove to the side close to the treatment cavity 31, in the process of moving, the sliding rod 24 drives the fixed plate 23 to move, the fixed plate 23 drives the impact block 25 to move to the side close to the treatment cavity 31, the impact block 25 impacts the top of the treatment cavity 31 when moving, and the vibration generated by the impact is transmitted to the sedimentation cavity 11.

[0049] In the process of moving, the fixed plate 23 drives the reciprocating barrel 21 to move, the reciprocating barrel 21 drives the permeation plate 26 to move, when the sliding rod 24 moves to the bottom end of the sliding groove, at this time, the surface of the reciprocating barrel 21 is just below the surface of the wastewater, and the surface layer of the wastewater is immediately transported into the reciprocating barrel 21, in the process of transporting the wastewater, the controller controls the motor to reverse, and then the transmission shaft 13 reverses to drive the sliding rod 24 to rise, the sliding rod 24 drives the fixed plate 23 to move to the side close to the sedimentation cavity 11, that is, the fixed plate 23 drives the reciprocating barrel 21 to rise, and the height of the upper surface of the reciprocating barrel 21 is immediately higher than the height of the surface of the wastewater, and the wastewater in the reciprocating barrel 21 is transported to the side close to the extension pipe 22 through the permeation plate 26.

[0050] The reciprocating barrel 21 transports the surface layer of the wastewater under the action of the reciprocating movement of the sliding rod 24, and the sliding rod 24 reciprocatingly drives the impact block 25 to reciprocatingly impact the treatment cavity 31, the vibration generated by the impact block 25 is transmitted to the treatment cavity 31 and the sedimentation cavity 11 through the machine body 1, so that the wastewater in the sedimentation cavity 11 speeds up the sedimentation speed under the action of the vibration wave; the wastewater transported into the extension pipe 22 is transported into the water flow groove 28 through the extension pipe 22, and then flows into the water flow inlet 281 through the water flow groove 28, and finally is sprayed out of the two cylindrical pipes 32 through the water flow inlet 281.

[0051] The wastewater flows through the water outlet 281 to the cylindrical pipe 32, and the reciprocating barrel 21 reciprocates along the axis. During the movement of the reciprocating barrel 21, the extension pipe 22 is moved, and the extension pipe 22 drives the extrusion strip 27 to move to one side close to the air bag 34. When the extrusion strip 27 moves, the air bag 34 is extruded, and the air bag 34 moves to the side close to the conveying cavity 33. At this time, the pressure in the air bag 34 is greater than the pressure in the treatment cavity 31, and the coagulant in the air bag 34 is immediately conveyed through the output port 341. The coagulant is sprayed through the plurality of output ports 341. Since the plurality of output ports 341 are arranged around the axis of the cylindrical pipe 32, the plurality of coagulants move from the edge of the cylindrical pipe 32 to the center of the cylindrical pipe 32, thereby increasing the contact area between the wastewater and the coagulant. At the same time, the vibration wave generated by the impact of the impact block 25 is transmitted to the cylindrical pipe 32 through the treatment cavity 31, and the vibration wave is transmitted to the wastewater in the cylindrical pipe 32, thereby accelerating the movement between the wastewater and the coagulant.

[0052] During the mixing of the coagulant and the water, the controller controls the electromagnetic coil in the cylindrical pipe 32 to be energized. After the electromagnetic coil is energized, a magnetic force is generated, which attracts the rotating shaft 38 to rotate. When the rotating shaft 38 rotates, the spiral plate 39 is driven to rotate. During the rotation of the spiral plate 39, the spiral plate 39 stirs the wastewater and the coagulant, so that the wastewater and the coagulant rotate around the axis of the rotating shaft 38, thereby improving the mixing efficiency of the wastewater and the coagulant. At the same time, the spiral plate 39 moves the wastewater and the coagulated suspended matter in the cylindrical pipe 32 to the side close to the extrusion pipe 35. The wastewater and the coagulated suspended matter first enter the conical pipe 36. Since the number of spiral turns of the spiral plate 39 located in the cylindrical pipe 32 is less than the number of spiral turns of the spiral plate 39 located in the extrusion pipe 35, the wastewater and the coagulated suspended matter are extruded and compressed in the conical pipe 36. The wastewater is conveyed through the filter hole on the conical pipe 36 to the side close to the filter pipe 37, and the coagulated suspended matter is gathered at the end of the conical pipe 36 away from the cylindrical pipe 32. The filtered wastewater is conveyed through the filter pipe 37 to the water outlet, and the coagulated suspended matter is conveyed to the impurity cavity through the pipeline.

[0053] When the rotating shaft 38 rotates, the controller controls the external power supply to be powered on in stages, the power of the external power supply is transmitted to the conductive ring through the wire, since the spiral plate 39 is made of aluminum or zinc, and the spiral plate 39 is in sliding connection with the conductive ring, so that the spiral plate 39 is the anode, and the cylindrical pipe 32 is the cathode, under the action of the conductive ring, a potential difference is generated between the anode and the cathode, and then an electric current is generated through the potential difference, so that the anode forms an anode protection layer on the surface of the cylindrical pipe 32 under the action of the electric current, and then in the process of rotating the spiral plate 39, the mixing and stirring of the wastewater and the coagulant are completed, so that the mixing efficiency of the wastewater and the coagulant is improved, and the suspended matter of the wastewater and the coagulant is transported to the side close to the extrusion pipe 35, so that the wastewater is separated, and an electric current is formed by the potential difference, and a protection layer is formed on the surface of the cylindrical pipe 32 under the action of the electric current, thereby improving the corrosion resistance of the surface of the cylindrical pipe 32, prolonging the maintenance time of the cylindrical pipe 32, and prolonging the stable operation time of the equipment.

[0054] When water supply is needed, the controller controls the start of the pressurizing pump in the water storage tank, and the pressurizing pump transports the water in the water storage tank after pressurizing. The worker controls the power of the pressurizing pump through the PLC controller according to the required water quantity, so as to realize water supply in the full-band power.
