Description

Technical Field

[0001] This utility model relates to the field of purification devices, specifically a wastewater and sludge drying device for a fluorescence detection line. Background Technology

[0002] Fluorescent wastewater from fluorescence detection lines typically requires solid-liquid separation using a plate and frame filter press. After separation, the waste liquid is returned to the wastewater treatment plant, while the separated and pressed sludge is outsourced for treatment. However, in existing solutions, after the sludge is concentrated and pressed, a thin film forms on its surface. This film may retain some liquid, resulting in solid particles with a water content of approximately 95% to 97%, which is still quite large. Outsourcing treatment is inconvenient and costly. Utility Model Content

[0003] To overcome the deficiencies in the prior art, this utility model provides a fluorescent detection line wastewater sludge drying device, which is used to solve one or more of the above-mentioned problems.

[0005] Furthermore, the two ends of the connecting pipe are respectively connected to the fluorescent wastewater storage tank and the plate and frame filter press, and the diaphragm pump is installed on the connecting pipe.

[0006] Furthermore, the plate and frame filter press includes a feed inlet and a liquid outlet respectively disposed on both sides and a solid outlet located at the bottom, wherein the feed inlet is connected to the connecting pipe.

[0007] Furthermore, it also includes a sludge cart, which is located at the lower end of the solid outlet in the plate and frame filter press and is used to collect solid particles after solid-liquid separation of fluorescent wastewater. The sludge cart can move relative to the plate and frame filter press.

[0008] Furthermore, the sludge trolley has a material container with a cross-sectional area that gradually increases upward in the vertical direction, and the upper cross-sectional area of ​​the material container is larger than the solid outlet cross-sectional area in the plate and frame filter press.

[0009] Furthermore, the compressed air drying system includes a filter press compressed air unit disposed at the feed inlet of the plate and frame filter press, the filter press air unit being used to blow compressed air onto the solid particles located inside the plate and frame filter press.

[0011] Furthermore, it also includes a wastewater treatment station, which is connected to the outlet of the plate and frame filter press to treat the collected liquid.

[0012] The beneficial effects of this utility model are as follows:

[0013] By spraying compressed gas onto solid particles and drying them, the force of the gas flow can be used to carry away residual liquid from the surface of the solid particles, achieving more thorough and efficient solid-liquid separation. This allows the solid particles to be completely dried, thereby reducing the cost of outsourcing sludge treatment.

[0018] 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.

[0019] like Figure 1 As shown, a wastewater sludge drying device for a fluorescence detection line in this embodiment includes:

[0020] Fluorescent wastewater storage tank 1 is used to place and store fluorescent wastewater, wherein the fluorescent wastewater is a solid-liquid mixture of solid particles and waste liquid.

[0021] A plate and frame filter press 2 is connected to the fluorescent wastewater storage tank 1. The plate and frame filter press 2 is used to perform solid-liquid separation on the fluorescent wastewater flowing through it. After being transferred from the fluorescent wastewater storage tank 1 to the plate and frame filter press 2, the fluorescent wastewater is subjected to pressure in the pre-compression chamber of the plate and frame filter press 2. This causes the solid-liquid mixture of fluorescent wastewater to distribute on the filter plates. After pre-compression, the fluorescent wastewater enters the filtration chamber composed of filter plates and filter frames. Under the action of the hydraulic system, a certain pressure difference is generated between the filter plates, causing the liquid to permeate through the filter cloth to the other side of the filtration chamber under pressure. Solid particles are trapped on the surface of the filter cloth and gradually accumulate to form a filter cake, thereby achieving solid-liquid separation of the fluorescent wastewater mixture into waste liquid and solid particles.

[0022] A diaphragm pump 3 is disposed between the fluorescent wastewater storage tank 1 and the plate and frame filter press 2. The diaphragm pump 3 is used to control the flow of fluorescent wastewater from the fluorescent wastewater storage tank 1 to the plate and frame filter press 2, and to control the flow rate and velocity of the fluorescent wastewater during this process.

[0023] The compressed air drying system 4 is used to spray compressed air onto the solid particles in the fluorescent wastewater, thereby drying the solid particles after solid-liquid separation. The liquid remaining in the solid particles is discharged by high-pressure gas, making the solid-liquid separation more thorough and efficient.

[0024] In this embodiment, after the fluorescent wastewater in the fluorescent wastewater storage tank 1 is transferred to the plate and frame filter press 2, it is subjected to pressure in the pre-compression chamber of the plate and frame filter press 2. This causes the solid-liquid mixture of fluorescent wastewater to be distributed on the filter plates. After pre-compression, the fluorescent wastewater enters the filtration chamber composed of filter plates and filter frames. Under the action of the hydraulic system, a certain pressure difference is generated between the filter plates, causing the liquid to permeate through the filter cloth to the other side of the filtration chamber under pressure, while the solid particles are trapped on the surface of the filter cloth and gradually accumulate to form a filter cake. Experiments have shown that the solid particles in the filter cake still have a water content of about 95% to 97%. The compressed air drying system 4 sprays high-pressure gas onto the solid particles through a gas pipeline, using the force of the gas flow to carry away the residual liquid from the surface of the solid particles, achieving more thorough and efficient solid-liquid separation, so that the solid particles can be completely dried.

[0025] By using the above structure, compressed gas is sprayed onto solid particles and dried. The force of the gas flow can be used to remove residual liquid from the surface of the solid particles, achieving more thorough and efficient solid-liquid separation. This allows the solid particles to be completely dried, thereby reducing the cost of outsourcing sludge treatment.

[0026] Specifically, the system includes a connecting pipe 5, with its two ends connected to the fluorescent wastewater storage tank 1 and the plate and frame filter press 2, respectively. A diaphragm pump 3 is installed on the connecting pipe 5. This allows the connecting pipe 5 to guide the fluorescent wastewater moving from the fluorescent wastewater storage tank 1 to the plate and frame filter press 2, and the diaphragm pump 3 controls the flow rate and velocity of the fluorescent wastewater, making the transfer process more efficient and stable.

[0027] Specifically, the plate and frame filter press 2 includes an inlet and an outlet on both sides, and a solid outlet at the bottom. The inlet is connected to the connecting pipe 5, allowing the fluorescent wastewater in the flow pipe to enter the plate and frame filter press 2 through the inlet. After being fully filtered, the waste liquid flows out through the outlet after passing through the horizontally arranged filter plates in the plate and frame filter press 2, thus ensuring that the outflowing liquid is fully filtered. The solid outlet, located at the bottom, allows solid particles to fall out of the plate and frame filter press 2 by gravity, thereby improving the collection efficiency of solid particles.

[0028] Specifically, it also includes a sludge cart 6, located at the lower end of the solid outlet in the plate and frame filter press 2, for collecting solid particles after solid-liquid separation of fluorescent wastewater. The sludge cart 6 can move relative to the plate and frame filter press 2. This allows the sludge cart 6 to move the solid particles away from the plate and frame filter press 2 after collecting them, thus achieving the effect of moving the dried solid particles away from the plate and frame filter press 2. Preferably, the sludge cart 6 has a material container with a cross-sectional area that gradually increases upwards in the vertical direction. The upper cross-sectional area of ​​the material container is larger than the cross-sectional area of ​​the solid outlet in the plate and frame filter press 2, allowing the dried solid particles to fall completely into the sludge cart 6. Once inside the sludge cart 6, they can be collected by the guiding effect of the material container, improving the efficiency of solid particle collection.

[0029] Specifically, the compressed air drying system 4 includes a filter press compressed air unit 41 located at the feed inlet of the plate and frame filter press 2. This unit blows compressed air onto the solid particles located inside the plate and frame filter press 2. The compressed air drying system 4 can be connected to the feed inlet via an air inlet pipe distinct from the connecting pipe 5, allowing the compressed air in the system to dry the solid particles after solid-liquid separation, resulting in better drying performance. Preferably, the compressed air drying system 4 further includes a diaphragm compressed air unit 42 connected to the diaphragm pump 3, which blows compressed air onto the fluorescent wastewater in the diaphragm pump 3. Since the diaphragm pump 3 is used to control the flow rate and volume of fluorescent wastewater through pressure, the compressed air in the diaphragm compressed air unit 42 can pre-dry the solid particles in the fluorescent wastewater in the solid-liquid mixed state. Combined with the compressed air in the subsequent filter press compressed air unit 41, the solid particles are dried in two stages by compressed air, resulting in a better drying effect for the solid particles.

[0030] Specifically, it also includes a wastewater treatment station 7, which is connected to the outlet of the plate and frame filter press 2 to treat the collected liquid, thereby realizing the treatment of waste liquid after solid-liquid separation.

[0031] This utility model uses specific embodiments to illustrate the principle and implementation of the utility model. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​the utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​the utility model. Therefore, the content of this specification should not be construed as a limitation of the utility model.
