[0030] 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.

[0031] Please see Figure 1-5 This utility model provides a technical solution:

[0032] A hazardous waste solid-liquid separation device, comprising:

[0033] Separation box 1, waste pipe 2 is fixedly connected to the upper end of separation box 1, and separation components for separating solid and liquid waste are installed inside separation box 1;

[0034] An air handling unit 12 for filtering gases emitted from waste is provided at the upper end of the separation box 1;

[0035] A liquid level display component 13 for displaying the liquid level is provided on the side wall of the separation tank 1.

[0036] The air handling unit 12 includes a sieve plate 121, a connecting pipe 122, a handling box 123, an activated carbon plate 124, a circulating air pump 125, a connecting pipe, and an air outlet pipe 127.

[0037] The separation box 1 has a sieve plate 121 fixedly connected to the top of its interior, a connecting pipe 122 fixedly connected to the upper end of the separation box 1, a processing box 123 fixedly connected to one end of the connecting pipe 122, an activated carbon plate 124 inside the processing box 123, a circulating air pump 125 on the side wall of the processing box 123, a connecting pipe 126 fixedly connected to the side wall of the circulating air pump 125, and an air outlet pipe 127 fixedly connected to the lower end of the connecting pipe 126.

[0038] Through the cooperation of structures such as sieve plate 121 and connecting pipe 122, sieve plate 121 intercepts solid particles to prevent them from entering the gas treatment system. Connecting pipe 122 guides the waste gas from the separation box to the treatment box 123, which is made of corrosion-resistant material (such as PP or 316L stainless steel). The treatment box 123 has a built-in multi-layer activated carbon plate 124, which decomposes harmful gases (such as VOCs and hydrogen sulfide) through physical adsorption and chemical catalysis. The circulating air pump 125 forces airflow circulation to improve treatment efficiency. The exhaust pipe 127 discharges the purified gas and simultaneously dries the solid waste. This technology solves the problem of environmental pollution caused by waste gas in the waste. The recommended model for circulating air pump 125 is the Gardner Denver EH series corrosion-resistant centrifugal fan (such as EH-0250).

[0039] The liquid level display assembly 13 includes a transparent tube 131, a limiting ring 132, a float 133, a control button 134, and a buzzer 135;

[0040] The separation box 1 has a transparent tube 131 fixedly connected inside its side wall, two evenly distributed limiting rings 132 fixedly connected inside the transparent tube 131, a float plate 133 slidably connected inside the transparent tube 131, a control button 134 fixedly connected to the upper end of the transparent tube 131, and a buzzer 135 electrically connected to the upper end of the control button 134.

[0041] Through the cooperation of structures such as the transparent tube 131 and the limiting ring 132, the transparent tube 131 is made of high-strength glass or polycarbonate, which is impact-resistant and chemically resistant. It is connected to the liquid level of the separation tank 1. The float 133 slides between the limiting rings 132 as the liquid level rises and falls. When the float 133 touches the top control button 134, the buzzer 135 is activated to remind the staff to release the waste liquid. This solves the technical problem that the height of the internal liquid level is not easy to observe. The float 133 is supported by hollow metal and wrapped with polytetrafluoroethylene for corrosion protection. The recommended model of the control button 134 is the Schneider Harmony XB5 series explosion-proof button (XB5AD81), and the recommended model of the buzzer 135 is Patlite NHS-12 (24V DC, sound pressure ≥85dB).

[0042] The separation assembly includes a filter plate 3, a cam rod 4, and a drive motor 5;

[0043] The filter plate 3 is slidably connected inside the separation box 1. The lower end of the filter plate 3 contacts the cam rod 4. The cam rod 4 is rotatably connected to the separation box 1. One end of the cam rod 4 passes through the separation box 1 and is fixedly connected to the drive motor 5. The drive motor 5 is fixedly connected to the separation box 1. The lower end of the filter plate 3 is provided with a guide component for guiding.

[0044] Through the cooperation of the filter plate 3 and cam rod 4, the pore size of the filter plate 3 is customized according to the particle size of the waste (e.g., 0.1-5mm). The material is stainless steel or ceramic filter membrane, which is resistant to acid and alkali corrosion. The cam rod 4 is driven to rotate eccentrically by the drive motor 5, which causes the filter plate 3 to vibrate up and down, thus accelerating the solid-liquid separation. This solves the technical problem of poor filtration effect when using only the filter plate 3. The recommended model of the drive motor 5 is the Siemens 1LE0 series explosion-proof motor (e.g., 1LE0001-1DA43-2FA4).

[0045] The guide assembly includes a lifting frame 6 and a fixed frame 7;

[0046] Among them, the lower end of the filter plate 3 is fixedly connected to a plurality of symmetrically distributed lifting frames 6, and the outer sides of the plurality of lifting frames 6 are slidably connected to fixed frames 7, and the plurality of fixed frames 7 are respectively fixedly connected to the separation box 1.

[0047] By combining the lifting frame 6 and the fixed frame 7, the technical effect of ensuring the vertical movement of the filter plate is achieved, avoiding uneven wear, and extending the service life is realized, and the technical problem of the filter plate 3 easily shifting when it is raised and lowered is solved.

[0048] The separation box 1 is fixedly connected to a partition 8, which is slidably connected to the filter plate 3.

[0049] By combining the separation box 1 and the partition 8, the partition 8 achieves the technical effect of limiting solid waste, solving the technical problem that solid waste is easy to fly out when the filter plate 3 is raised and lowered. An inclined plate 9 is provided on the side wall of the partition 8, which facilitates the discharge of solid waste.

[0050] The separation box 1 is equipped with an inclined conveyor belt 10 inside. The surface of the conveyor belt 10 is provided with a storage groove composed of multiple baffles. A solid collection box 11 is fixedly connected to the side wall of the separation box 1. A sealed door is provided on the side wall of the solid collection box 11.

[0051] By cooperating with the structure of the conveyor belt 10 and the solid collection box 11, the technical effect of the conveyor belt 10 transporting solid waste out of the separation box 1 and the solid collection box 11 collecting solid waste is achieved, which solves the technical problem that solid waste is inconvenient to collect. The bottom of the separation box 1 is equipped with a waste liquid pipe 14, which is opened when the liquid level is high to discharge the liquid.

[0052] Working principle: The mixed solid-liquid waste is slowly poured into the separation box 1 through the waste pipe 2. The drive motor 5 is turned on, which drives the cam rod 4 to rotate, causing the filter plate 3 to vibrate up and down. When the filter plate 3 rises to the top, the solid waste enters the conveyor belt 10 through the partition plate 8 and the inclined plate 9. The conveyor belt 10 transports the solid waste out of the separation box 1, and the solid collection box 11 collects the solid waste.

[0053] Under the action of the circulating air pump 125, the waste gas intercepts solid particles through the sieve plate 121 and enters the treatment box 123 through the connecting pipe 122. The activated carbon plate 124 adsorbs harmful gases such as VOCs and hydrogen sulfide. The purified gas is discharged through the air outlet pipe 127 and the solid waste on the conveyor belt 10 is dried.

[0054] The liquid level is monitored by the transparent tube 131. The float 133 will rise and fall with the liquid level. If the liquid level is close to the upper limit, the float 133 will trigger the control button 134 and the buzzer 135 will sound an alarm. At this time, the liquid drainage will be started.

[0055] In this application, the drive motor 5, conveyor belt 10, circulating air pump 125, control button 134, and buzzer 135 are controlled automatically by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, this application is mainly used to protect the structure, shape, and their combination, so this application will not explain the control method and circuit connection in detail. The device is powered by a built-in power supply or an external power supply.

[0056] 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.
