Description

Technical Field

[0001] This utility model relates to the field of liquid treatment technology, specifically a landfill leachate treatment device. Background Technology

[0002] Landfill leachate treatment facilities are used to treat leachate generated from landfills. This leachate is a mixture of pollutants and harmful substances dissolved in water when rainwater or other liquids come into contact with the waste. The goal of the treatment is to prevent these harmful components from polluting the environment and water sources.

[0003] In existing technologies, when treating landfill leachate, the treated leachate has a strong odor, which can easily affect people in the surrounding area.

[0004] To overcome the above shortcomings, a prior art Chinese patent (publication number CN212126372U) discloses a landfill leachate treatment device, comprising a shell and a top cover. A pair of pillars are symmetrically arranged on the left and right sides of the top of the shell, and the left and right ends of the top cover are connected to the corresponding pillars. The pair of pillars are connected by a crossbeam. An internal bin for collecting waste is provided inside the shell. The internal bin includes a bottom plate and side plates. First leakage holes are evenly arranged on the bottom plate to drain the liquid flowing from the internal bin. A collection hopper is placed below the internal bin to collect the liquid seeping from it. The collection hopper is slidably connected to the shell. A spray unit is connected to the shell for spraying deodorizing agent into the internal bin. This solves the problem that currently, landfill leachate and solid waste are simultaneously retained in the internal bin, and liquid often leaks out during cleaning and dumping, which is very inconvenient. Furthermore, by setting up the spray unit, the problem of a strong odor remaining in the internal bin after waste cleaning, affecting the surrounding air environment, is alleviated.

[0005] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation. For example, when treating leachate, the leachate accumulates on the surface of the filter screen after passing through it. When removing the accumulated waste, some residue may fall into the device, making the process cumbersome and inconvenient. Utility Model Content

[0006] The purpose of this utility model is to provide a landfill leachate treatment device to solve the problem mentioned in the background art that when treating landfill leachate, the leachate accumulates on the surface of the filter screen after passing through it, and when the accumulated landfill is removed, some residue easily falls into the device, making the process cumbersome and inconvenient.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a landfill leachate treatment device, comprising a housing and an inlet at the upper end of the housing, wherein the front end of the housing is connected to an electronic discharge port, and a filter screen is provided inside the housing; a groove is provided inside the housing, and a quick-opening and closing mechanism is provided inside the groove, wherein the quick-opening and closing mechanism includes a positioning locking plate, and the positioning locking plate is located inside the groove; a deodorizing agent chamber is installed at the rear end of the housing, and a deodorizing treatment mechanism is provided at the bottom of the deodorizing agent chamber, wherein the deodorizing treatment mechanism includes a connecting channel, and the upper and lower ends of the connecting channel are respectively connected to the deodorizing agent chamber and the housing.

[0008] Furthermore, the quick opening and closing mechanism also includes a slot, which is formed on the surface of the filter screen and is inclined. The positioning locking plate corresponds to the slot.

[0009] Furthermore, the positioning locking plate is slidably connected to the groove, and a first fixing plate is fixedly installed at the front end of the positioning locking plate, and a second fixing plate is fixedly installed at the front end of the housing, and a return spring is provided between the second fixing plate and the first fixing plate.

[0010] Furthermore, the first fixing plate is slidably connected to the housing, and a first damper is provided between the first fixing plate and the second fixing plate at the middle.

[0011] Furthermore, the deodorization treatment mechanism also includes a water turbine plate, and the front and rear ends of the water turbine plate are rotatably connected to the interior of the housing, and the upper end of the water turbine plate corresponds to the feed inlet.

[0012] Furthermore, a gathering wheel is fixedly installed at the rear end of the water turbine plate, and a traction rope is provided on the surface of the gathering wheel. A horizontal plate is fixedly installed at the lower end of the traction rope, and a sealing plate is fixedly installed at the lower end of the horizontal plate.

[0013] Furthermore, the lower end of the sealing plate is fitted to the inner wall of the connecting channel, and a buffer spring is provided between the lower end of the horizontal plate and the connecting channel. A second damper is installed through the middle of the horizontal plate, and the lower end of the second damper is installed on the surface of the connecting channel.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. During use, leachate is added to the inside of the housing through the feed inlet. After the leachate enters the housing, it washes the filter screen and filters the leachate. Impurities remain on the filter screen, and the filtered leachate is discharged through the electronic discharge port. If the filter screen needs to be removed, the first fixing plate is moved upward, which moves the positioning locking plate and squeezes the reset spring. This causes the positioning locking plate to slide along the groove and disengage from the slot, allowing the filter screen to be easily removed, thus removing the filter screen plate with surface impurities.

[0016] Furthermore, after cleaning the surface of the filter screen, it is aligned with the opening at the front end of the housing and inserted, so that the rear end of the filter screen plate presses against the positioning locking plate. With the setting of the return spring and the first damper, the positioning locking plate can be inserted into the slot to lock and position the filter screen, thus achieving the effect of convenient installation of the filter screen.

[0017] 2. During use, as leachate is added through the inlet, it impacts the water wheel plate. The impact causes the water wheel plate to rotate, pulling the traction rope which wraps around it. This traction rope then pulls the horizontal plate and sealing plate, opening the seal between the sealing plate and the connecting channel. At this point, the deodorizing agent inside the deodorizing agent chamber can enter the housing through the connecting channel, allowing for automatic addition of deodorizing agent. The deodorizing agent mixes with the leachate to achieve a deodorizing effect.

[0018] Furthermore, when the water turbine plate stops being impacted, the buffer spring and the second damper cause the horizontal plate and the sealing plate to reset, thereby resealing the connection channel and achieving a resealing effect, which can save resources. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: As Figures 1-4 The technical solution shown is a landfill leachate treatment device. To solve the problem of inconvenient removal of landfill impurities, it discloses: a shell 1 and an inlet 2 at the upper end of the shell 1, with an electronic discharge port 3 connected to the front end of the shell 1, and a filter screen 4 inside the shell 1; a groove 5 inside the shell 1, and a quick-opening and closing mechanism inside the groove 5, including a positioning locking plate 6 located inside the groove 5; a slot 7 on the surface of the filter screen 4, with an inclined shape; the positioning locking plate 6 corresponding to the slot 7; the positioning locking plate 6 slidably connected to the groove 5; a first fixing plate 8 fixedly installed at the front end of the positioning locking plate 6; a second fixing plate 9 fixedly installed at the front end of the shell 1; a return spring 10 between the second fixing plate 9 and the first fixing plate 8; a slidably connected first fixing plate 8 to the shell 1; and a first damper 11 between the first fixing plate 8 and the second fixing plate 9 at the middle.

[0028] During use, leachate is added to the inside of the housing 1 through the feed inlet 2. After the leachate enters the housing 1, it washes the filter screen 4, filtering the leachate. Impurities remain on the filter screen 4, and the filtered leachate is discharged through the electronic discharge port 3. To remove the filter screen 4, the first fixing plate 8 is moved upwards, causing the positioning locking plate 6 to move upwards and press the return spring 10. This causes the positioning locking plate 6 to slide along the groove 5 and disengage from the slot 7, allowing the filter screen 4 to be easily removed. The filter screen plate 4 allows for easy removal of surface impurities. Conversely, after cleaning the surface of the filter screen plate 4, it is aligned with the opening at the front end of the housing 1 and inserted, causing the rear end of the filter screen plate 4 to press against the positioning locking plate 6. Due to the inclined shape of the bottom of the positioning locking plate 6, the positioning locking plate 6 is pushed upward. At this point, when the bottom of the positioning locking plate 6 corresponds to the slot 7, the positioning locking plate 6 can be inserted into the slot 7 and locked in place by the reset spring 10 and the first damper 11, thus achieving the effect of convenient installation of the filter screen plate 4.

[0029] Example 2: Figure 3 , Figure 5 and Figure 6 The technical solution shown, based on Embodiment 1, discloses the following to address the problem of strong odor: a deodorizing agent chamber 12 is installed at the rear end of the housing 1, and a deodorizing treatment mechanism is provided at the bottom of the deodorizing agent chamber 12. The deodorizing treatment mechanism includes a connecting channel 13, with its upper and lower ends respectively connected to the deodorizing agent chamber 12 and the housing 1. The deodorizing treatment mechanism also includes a water wheel plate 14, with its front and rear ends rotatably connected to the interior of the housing 1, and its upper end connected to the feed inlet 2. Correspondingly, a winding wheel 15 is fixedly installed at the rear end of the water turbine plate 14, and a traction rope 16 is provided on the surface of the winding wheel 15. A horizontal plate 17 is fixedly installed at the lower end of the traction rope 16, and a sealing plate 18 is fixedly installed at the lower end of the horizontal plate 17. The lower end of the sealing plate 18 is in contact with the inner wall of the connecting channel 13, and a buffer spring 19 is provided between the lower end of the horizontal plate 17 and the connecting channel 13. A second damper 20 is installed through the middle of the horizontal plate 17, and the lower end of the second damper 20 is installed on the surface of the connecting channel 13.

[0030] During use, as leachate is added through the feed inlet 2, it impacts the water turbine plate 14. The impact causes the rear-end winding wheel 15 to rotate, pulling the traction rope 16. The traction rope 16 is then pulled and wrapped around the winding wheel 15. This pull causes the horizontal plate 17 and sealing plate 18 to open the seal between the sealing plate 18 and the connecting channel 13. At this point, the deodorizing agent inside the deodorizing agent chamber 12 can enter the housing 1 through the connecting channel 13, thus automatically adding deodorizing agent. The deodorizing agent mixes with the leachate to achieve deodorization. Conversely, when the water turbine plate 14 stops being impacted, the buffer spring 19 and the second damper 20 reset the horizontal plate 17 and sealing plate 18, resealing the connecting channel 13 and saving resources.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
