Abstract
Description
Technical Field
[0001] The utility model relates to the field of garbage processing equipment, in particular to a leachate pump with a sampling function. Background Art
[0002] Leachate is a high-concentration, difficult-to-treat organic wastewater produced during the stacking, sorting, compression, landfill and fermentation of garbage. It mainly comes from the inherent water in the garbage itself, the water produced by the biochemical reaction of the garbage and atmospheric precipitation. In order to make domestic garbage more conducive to subsequent incineration, domestic garbage from all over the city will be collected and dumped into the garbage fermentation tank of the garbage incineration power plant for fermentation. In order to shorten the process and improve the fermentation efficiency, it is often necessary to transfer the leachate with good fermentation effect to the garbage fermentation tank. The leachate transfer method is to install the leachate pump in the leachate tank, and the leachate pump will lift the leachate and transmit it to the corresponding garbage fermentation tank through a pipeline.
[0003] During the transfer process, in order to ensure the subsequent fermentation effect, the leachate in the leachate pool needs to be sampled and analyzed regularly. The traditional sampling method is to sink the container into the leachate pool, and after the leachate fills the container, the container is lifted and transferred to the laboratory. This sampling method is cumbersome to operate and the leachate is easy to contact with the limbs during the operation, causing damage to the skin. Summary of the invention
[0004] In view of the deficiencies in the prior art, the utility model aims to provide a leachate pump with a sampling function which is efficient, convenient and clean.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: comprising a pump body located at the bottom of a leachate pool, a liquid outlet pipe being arranged on the side of the pump body, and characterized in that: it also comprises a lifting pipe, a sampling pipe and a sampling bottle, the lifting pipe being arranged vertically, the lower end of which is butted with the liquid outlet pipe, the upper end of which extends above the water surface and is provided with a lifting elbow bent to a horizontal state, the sampling pipe being arranged horizontally and one end of which is butted with the lifting elbow, the sampling pipe being provided with a transition channel axially therethrough, a sampling seat being arranged below the sampling pipe, and the middle part of the sampling seat being provided with a vertical A sampling central axis is arranged, a sampling channel connected with the transition channel is arranged vertically in the sampling central axis, a plurality of branch channels radially extending to the outside of the sampling central axis are arranged at the lower end of the sampling channel, a force-bearing sealing disk which surrounds the sampling central axis and slides vertically and a reset member which resets the force-bearing sealing disk downward are arranged in the sampling seat, the branch channels are closed when the force-bearing sealing disk is in the lowest position, after the sampling central axis penetrates into the sampling bottle from the bottle mouth, the container wall around the bottle mouth of the sampling bottle presses the force-bearing sealing disk upward, and after the force-bearing sealing disk and the branch channel are misaligned, the branch channel is connected with the sampling bottle.
[0006] By adopting the above technical scheme, the length of the lifting pipeline is selected according to the depth of the leachate pool, and the leachate is guided to the sampling pipeline above the ground by the lifting pipeline. When sampling, hold the sampling bottle, align the mouth of the sampling bottle with the sampling center axis, press the sampling bottle upward, and after the force sealing disk and the branch channel are misaligned, the branch channel is connected to the sampling bottle, and the leachate enters the sampling bottle. After the sampling is completed, just let go. The above sampling method has the following advantages: ① The staff standing on the shore can start sampling by simply holding the sampling bottle and pressing the force sealing disk with the bottle mouth, and stop sampling by letting go, thereby realizing online rapid sampling, and the operation is more efficient and convenient; ② In addition to the function of closing the branch channel, the force sealing disk also closes the mouth of the sampling bottle during the sampling process to prevent the leachate from splashing onto the skin, and the operation is cleaner; ③ The sampling pipeline is subsequently connected to other transmission pipelines to continue the normal transmission of the leachate. As an optional module, the sampling pipeline does not affect the original leachate transfer function when it is added or reduced, which is in line with the current modular trend to improve ease of use.
[0007] The utility model is further configured as follows: the sampling seat is provided with a guide wall surrounding the force-bearing sealing disk, the inner periphery of the guide wall and the outer periphery of the sampling center axis form a sliding cavity for the force-bearing sealing disk to slide vertically, the lower end of the guide wall is provided with a limiting folded edge bent inwardly, and the reset member is a cylindrical compression spring sleeved on the sampling center axis and compressed between the sampling seat and the top of the force-bearing sealing disk.
[0008] By adopting the above technical scheme, the outer periphery of the sampling center axis is rationally utilized and cooperated with the inner periphery of the guide wall, so that the vertical sliding of the force-bearing sealing disk is more stable. At the same time, a limiting fold is added, so that the force-bearing sealing disk can be stably maintained after reaching the lowest position. In addition, the space of the sliding cavity is rationally utilized for installing the reset part, so that the reset force of the reset part is more stable and accurate.
[0009] The utility model is further configured as follows: the lower end surface of the force-bearing sealing disk is covered with a rubber layer.
[0010] By adopting the above technical solution, the rubber layer has two functions. On the one hand, it is compressed between the force-bearing sealing disk and the limiting folded edge to prevent leakage of leachate in the branch channel. On the other hand, it is compressed between the mouth of the sampling bottle and the force-bearing sealing disk to improve the sealing of the bottle mouth during the sampling process.
[0011] The utility model is further configured as follows: the branch channels are arranged in a cross with the sampling channel as the center.
[0012] By adopting the above technical solution, since there are a small amount of particles in the leachate, the cross-arranged branch channels can ensure sufficient pore size for the particles to pass through, avoiding blockage.
[0013] The utility model is further configured as follows: a vent hole is provided on the side of the sampling seat to connect the sliding cavity with the outside.
[0014] By adopting the above technical solution and adding air holes, it is avoided that the air pressure in the closed sliding cavity increases when the space is reduced, which hinders the sampling bottle from squeezing the stressed sealing disk, making the operation smoother.
[0015] The utility model is further configured as follows: the sampling bottle includes an extrusion section and a storage section in sequence along the direction away from the bottle mouth; the diameter of the storage section is larger than the diameter of the extrusion section and forms a splash-proof step at the connection to prevent liquid from splashing out; the outer periphery of the extrusion section is provided with an external thread.
[0016] By adopting the above technical scheme, the sampling bottle is divided into an extrusion section and a storage section, and the diameter of the storage section is larger than the diameter of the extrusion section. On the one hand, a splash-proof step is formed to prevent liquid from splashing out, further reducing the possibility of liquid splashing out when removing the sampling bottle, thereby protecting the staff; on the other hand, the storage section with a larger diameter is easier to hold, and the extrusion section with a smaller diameter is easier to apply force to the force-bearing sealing disk. In addition, the outer periphery of the extrusion section has an external thread, and after the sampling is completed, it can be sealed in time with a bottle cap with an internal thread, thereby improving practicality.
