Description

Technical Field

[0001] The invention relates to the technical field of municipal drainage equipment, and in particular to a large stainless steel assembled prefabricated pump station. Background Art

[0002] With the development of industry, the amount of sewage is increasing, so various sewage treatment equipment have emerged, and pumping station is one of them. Generally, sewage contains a certain amount of garbage and sludge.

[0003] During the flood season, sewage containing garbage and sludge enters the pump station through the water inlet. As the sewage in the pump station increases, when the sewage pushes the liquid float in the pump station to the standard liquid level, the vertical submersible pump at the bottom of the pump station will transport the sewage and garbage to the outlet for discharge. However, when the dry season comes, the sewage discharged into the pump station will decrease, making it impossible for the sewage level in the pump station to push the liquid float to the outlet level. At this time, the sludge and garbage will settle at the bottom of the pump station, thereby blocking the vertical submersible pump and coupling device at the bottom of the pump station, thereby causing damage to the internal components of the pump station.

[0004] Therefore, the present application provides a large stainless steel assembled prefabricated pump station to meet the needs. Summary of the invention

When the pump station body enters sewage next time, the garbage and sludge can be discharged through the water outlet of the pump station body at the same time, so as to solve the problem that the existing pump station cannot discharge the sludge and garbage in the pump station in time when the dry season comes, thereby causing equipment damage.

Connecting pipes 148 are fixedly installed on all sides of the top of the water collection cylinder 147. Four groups of connecting pipes 148 are respectively connected to the inside of the four groups of water storage cylinders 145 in a sealed manner. An L-shaped pipe 149 is sealed and fixedly connected to the bottom of the water collection cylinder 147. The L-shaped pipe 149 passes through one side of the support cylinder 110.

When the electromagnet device 160 is powered off, the magnetic force generated by the inner magnetic core 161 disappears. Under the action of the spring 156, the blocking rod 154 is reset, and the blocking block 144 and the water inlet trough 153 are blocked again. The electromagnet device 160 is fixedly installed on the inner wall of the bottom of the water storage cylinder 145, and the top of the electromagnet device 160 is set There are four groups of inner magnetic cores 161, and the electromagnet device 160 can magnetize the inner magnetic cores 161. The four groups of inner magnetic cores 161 are fixedly connected to the bottoms of the four groups of introduction tubes 150 respectively. In the present invention, the electromagnet device 160 is energized to magnetize the inner magnetic cores 161, thereby attracting the armature 155, causing the blocking rod 154 to move downward and compress the spring 156.

At the same time, the motor 131 is driven to open the three groups of special-shaped closing plates 127, thereby flushing the garbage and sludge in the mud storage cylinder 143 into the bottom of the pump station body 200.When the pump station body 200 enters sewage next time, garbage and sludge can be discharged through the outlet of the pump station body 200 at the same time.

[0041] In this embodiment, if Figures 14 to 18As shown, the conduction component 120 includes an annular seat 121, the outer wall of the annular seat 121 is sealed and fixed to the inner wall of the top of the support cylinder 110, the top of the top seat 141 is fixedly connected to the bottom of the annular seat 121 by bolts, and the center lines of the annular seat 121 and the top seat 141 coincide with each other, the support cylinder 110 is connected to the inside of the pump station body 200 through the conduction component 120, an annular hole is provided in the middle of the annular seat 121, and the sludge at the bottom of the pump station body 200 can enter the support cylinder 110 through the annular hole, an annular groove 122 is provided on the inner wall of the annular seat 121, and an arc-shaped bar 123 is rotatably connected to the inner wall of the annular groove 122, the arc-shaped bar 123 is provided with three groups, and is arranged in an equilateral triangle, and an arc-shaped rack 124 is fixedly installed on the top of the arc-shaped bar 123. The tops of two adjacent groups of arc-shaped rack gears 124 are fixedly installed with arc-shaped bars 125, which play the role of connecting the three groups of arc-shaped rack gears 124, so that when any group of arc-shaped rack gears 124 rotates, the other two groups of arc-shaped rack gears 124 can be driven to rotate through the arc-shaped bars 125. The top centers of the three groups of arc-shaped rack gears 125 are fixedly installed with arc-shaped bars 126. The inner wall of the top of the annular seat 121 is fixedly installed with an annular cover plate 132. The inner wall of the bottom of the annular cover plate 132 is provided with three groups of arc-shaped inner grooves 133. The three groups of arc-shaped bars 126 are respectively located in the three groups of arc-shaped inner grooves 133 and are rotatably connected with the arc-shaped inner grooves 133. The arc-shaped inner grooves 133 limit the arc-shaped bars 126 to prevent the arc-shaped rack gears 124 from rotating. 24 excessive rotation, causing the arc-shaped rack 124 to be out of coordination with the outer tooth pattern 128, the inner wall of the annular seat 121 is rotatably connected with three sets of special-shaped closing plates 127, the three sets of special-shaped closing plates 127 cooperate with each other, and can form a circular plate at the center of the annular seat 121, the three sets of special-shaped closing plates 127 are respectively located at the bottom of the three sets of arc-shaped bars 125, and the three sets of special-shaped closing plates 127 can just block the annular hole in the middle of the annular seat 121 when closed, the end wall of the special-shaped closing plate 127 is provided with an outer tooth pattern 128, and the outer tooth pattern 128 is meshed with the corresponding arc-shaped rack 124, the outer wall of the outermost arc-shaped bar 123 is fixedly installed with an arc-shaped rack 2 129, the inner wall of the annular seat 121 is rotatably connected with a gear 130, the gear 130 Meshing with the arc-shaped rack 2 129, a motor 131 is fixedly installed at the bottom of the annular seat 121, and the output end of the motor 131 is fixedly connected to the gear 130. In the present invention, the driving motor 131 makes its output shaft drive the gear 130 to rotate, so that the gear 130 is meshed with the arc-shaped rack 2 129, thereby driving the three groups of arc-shaped bars 123 to rotate, forcing the arc-shaped rack 124 on the inner side of the arc-shaped bar 123 to mesh with the outer tooth pattern 128, so that the three groups of special-shaped closing plates 127 move outward, thereby opening the three groups of special-shaped closing plates 127. At this time, the sludge and garbage at the bottom of the pump station body 200 and a small amount of sewage can enter the four groups of mud storage cylinders 143 through the conducting component 120 and the through hole 142.

[0042] The working principle of the technical solution provided by the present invention is as follows: in the dry season, only a small amount of sewage, sludge and garbage enters the bottom of the pump station body 200 through the water inlet. Due to the low content of sewage, the sewage level in the pump station body 200 cannot push the liquid float to the water outlet level, that is, the vertical submersible pump cannot work. If the sludge and garbage settle at the bottom of the pump station body 200 for a long time, the vertical submersible pump and the coupling device at the bottom of the pump station body 200 will be blocked, thereby damaging the internal components of the pump station body 200. At this time, the drive The motor 131 drives its output shaft to drive the gear 130 to rotate, so that the gear 130 meshes with the arc-shaped rack 2 129, thereby driving the three sets of arc-shaped bars 123 to rotate, forcing the arc-shaped rack 124 inside the arc-shaped bar 123 to mesh with the outer tooth pattern 128, so that the three sets of special-shaped closing plates 127 move outward, thereby opening the three sets of special-shaped closing plates 127. At this time, the sludge and garbage at the bottom of the pump station body 200 and a small amount of sewage can enter the four sets of mud storage cylinders through the conduction component 120 and the through hole 142 143, so that sludge and garbage can be precipitated and stored in the sludge storage cylinder 143. When the flood season arrives, a large amount of sewage will enter the pump station body 200, so that the liquid float can quickly reach the specified liquid level, and liquid water is introduced into the water collection cylinder 147 through the L-shaped tube 149, so that the liquid water enters the water storage cylinder 145 through the connecting pipe 148. When the water storage cylinder 145 is full of liquid, the electromagnet device 160 is energized to magnetize the inner magnetic core 161, thereby attracting the armature 155, so that the blocking rod 15 4 moves downward and compresses the spring 156. When the blocking rod 154 moves downward to the bottom of the water inlet groove 153, the liquid water in the water storage cylinder 145 can enter the introduction cylinder 150 through the water inlet groove 153, and then pass through the blocking block 144 to enter the mud storage cylinder 143. At the same time, the motor 131 is driven to open the three groups of special-shaped closing plates 127, so that the garbage and sludge in the mud storage cylinder 143 are flushed into the bottom of the pump station body 200. When the pump station body 200 enters sewage next time, the garbage and sludge can be discharged through the water outlet of the pump station body 200 at the same time.
