Description

Technical Field

[0001] This utility model relates to the field of concentrated brine treatment technology, and in particular to a waste residue drying device for concentrated brine treatment. Background Technology

[0002] Concentrated brine, also known as high-salinity wastewater, typically refers to wastewater with a total salt content greater than 1%. It mainly originates from industries such as chemical processing and the extraction and processing of petroleum and natural gas. Concentrated brine generally contains a variety of substances (including salt, oil, organic matter, heavy metals, and radioactive substances). Direct discharge of concentrated brine would cause serious environmental pollution. Therefore, concentrated brine must be treated before it can be discharged.

[0003] Existing concentrated brine treatment processes generate large amounts of waste residue containing various harmful substances. Direct dumping of this waste residue would cause serious pollution and harm to water systems and the atmosphere. One of the most common methods for treating this waste residue is drying and dehydration, followed by recycling. However, most current drying and dehydration equipment used for industrial waste residue recycling is complex in structure, inefficient, and unsuitable for long-term use.

[0004] Therefore, it is necessary to provide a waste residue drying device for concentrated brine treatment to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a waste residue drying device for concentrated brine treatment.

[0006] This utility model provides a waste residue drying device for concentrated brine treatment, comprising: a drying box with an open top, a heat transfer plate inside the drying box, an electric heating plate inside the drying box below the heat transfer plate, multiple hot air holes on the inner surface of the drying box, the hot air holes being connected to an air outlet through a hot air channel, the air outlet being located on the inner surface of the drying box below the heat transfer plate, an exhaust fan being installed inside the air outlet, one end of a first rotating shaft and one end of a second rotating shaft being connected to the two sides of the drying box respectively, the other end of the first rotating shaft passing through the side of a first support plate and connected to the drive end of a first motor, the other end of the second rotating shaft being rotatably connected to the side of the first support plate, and the tops of the first support plate and the second support plate being connected to the two ends of the top of a support base respectively.

[0009] Preferably, the top of the box cover on one side of the air outlet is provided with a plurality of second air outlets, and the second air outlets are connected to the peripheral side of the air outlet pipe through a second air outlet pipe.

[0010] Preferably, the top of the support base is provided with a recycling trough, and a recycling box with a top opening is installed inside the recycling trough.

[0011] Preferably, the hot air vent is truncated cone-shaped, and the size of the end of the hot air vent facing the inside of the drying oven is smaller than the size of the other end of the hot air vent.

[0012] Preferably, the outer surface of the first rotating shaft is sleeved on one end of the first limiting cylinder, and the outer surface of the other end of the first limiting cylinder is rotatably connected to the inner wall of the first limiting groove, the first limiting groove being disposed on the side of the first support plate; the outer surface of the second rotating shaft is sleeved on one end of the second limiting cylinder, and the outer surface of the other end of the second limiting cylinder is rotatably connected to the inner wall of the second limiting groove, the second limiting groove being disposed on the side of the second support plate.

[0013] Compared with related technologies, the waste residue drying equipment for concentrated brine treatment provided by this utility model has the following beneficial effects:

[0014] 1. This utility model uses an electric heating plate to heat a heat transfer plate, thereby increasing the temperature of the heat transfer plate and enabling the drying and dehydration of waste residue. Furthermore, the heat transfer plate acts as an insulator, preventing direct contact between the electric heating plate and the waste residue, which could cause the waste residue to stick to the heating plate, resulting in contamination and damage, affecting subsequent use. By incorporating hot air holes, the heat diffuses outwards during heating, and hot air is delivered through the air outlet and a fan to the area above the heat transfer plate, working in conjunction with the heat transfer plate to dry the waste residue, effectively improving the drying efficiency.

[0015] 2. This utility model, by setting up a recycling box with an air outlet, can collect the waste gas generated during the drying and dehydration process, preventing the waste gas from being directly emitted into the air and causing air pollution.

[0016] 3. By setting up hot air holes with a smaller outer diameter and a larger inner diameter, this utility model can effectively increase the flow rate of hot air flowing out of the hot air holes. The high-speed hot air facilitates the drying and dehydration of waste residue, thereby improving the efficiency of drying and dehydrating waste residue. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] refer to Figures 1 to 6This utility model provides a waste residue drying device for concentrated brine treatment, comprising: a drying box 1 with an open top, a heat transfer plate 25 inside the drying box 1, an electric heating plate 26 below the heat transfer plate 25 inside the drying box 1, a plurality of hot air holes 14 on the inner surface of the drying box 1, the hot air holes 14 being connected to air outlets 27 through hot air channels, the air outlets 27 being located on the inner surface of the drying box 1 below the heat transfer plate 25, an exhaust fan 28 being installed inside the air outlets 27, one end of a first rotating shaft 16 and one end of a second rotating shaft 20 being connected to the two sides of the drying box 1 respectively, the other end of the first rotating shaft 16 passing through the side of a first support plate 18 and connected to the drive end of a first motor 19, the other end of the second rotating shaft 20 being rotatably connected to the side of the first support plate 18, and the tops of the first support plate 18 and the second support plate 22 being connected to the two ends of the top of a support base 10 respectively.

[0026] It should be noted that: by setting a drying chamber 1 with a top opening, waste residue can be fed into the heat transfer plate 25 inside the drying chamber 1 using an existing feeding device. By setting an electric heating plate 26 below the heat transfer plate 25, the electric heating plate 26 can heat the heat transfer plate 25, thereby increasing the temperature of the heat transfer plate 25 and enabling the drying and dehydration of the waste residue. Furthermore, due to the isolation provided by the heat transfer plate 25, direct contact between the electric heating plate 26 and the waste residue is prevented during use, thus avoiding the waste residue sticking to the electric heating plate 26, causing contamination and damage to the electric heating plate 26, and affecting subsequent use. By setting a hot air hole 14, when the electric heating plate 26 is heating, the heat diffuses outward. Hot air can be sent into the area above the heat transfer plate 25 through the air outlet 27 and the exhaust fan 28, working in conjunction with the heat transfer plate 25 to dry the waste residue, effectively improving the drying effect of the waste residue.

[0027] In the embodiments of this utility model, reference is made to Figure 1 , Figure 2 As shown, the top of the drying box 1 is movably connected to the box cover 3. The top of the box cover 3 is provided with an air outlet 12. The air outlet 12 is connected to the recycling box 6 through an air outlet pipe 5. The top of the box cover 3 is connected to the bottom of the movable plate 7. The movable plate 7 is connected to the movable slide rail 8 through a slider. The bottom of the movable slide rail 8 is connected to the top of the support base 10.

[0028] It should be noted that by setting up a recycling box 6 with an air outlet 12, the waste gas generated during the drying and dehydration process can be collected through the recycling box 6, preventing the waste gas from being directly emitted into the air and causing air pollution.

[0029] In the embodiments of this utility model, reference is made to Figure 1 As shown, the bottom of the box cover 3 is provided with a connecting ring 4, and the top of the drying box 1 is provided with a connecting groove 2 that cooperates with the connecting ring 4.

[0030] It should be noted that by setting the connecting ring 4 and the connecting groove 2, on the one hand, the connecting groove 2 is used for positioning, which facilitates the connection between the box cover 3 and the drying box 1, and on the other hand, the connecting ring 4 improves the sealing of the connection between the box cover 3 and the top of the drying box 1.

[0031] In the embodiments of this utility model, reference is made to Figure 1 , Figure 2 As shown, the top of the box cover 3 on one side of the air outlet 12 is provided with a plurality of second air outlets 13, and the second air outlets 13 are connected to the peripheral side of the air outlet pipe 5 through the second air outlet pipe 9.

[0032] It should be noted that by setting a second air outlet 13, the efficiency of collecting the waste gas generated during the drying and dehydration process can be improved.

[0033] In the embodiments of this utility model, reference is made to Figure 1 , Figure 3 As shown, the top of the support base 10 is provided with a recycling trough 15, and a recycling box 11 with a top opening is installed inside the recycling trough 15.

[0034] It should be noted that by setting up the recycling box 11, the waste residue after drying and dehydration can be collected through the recycling box 11, preventing the waste residue from being directly discharged into the outside world after drying and dehydration, causing secondary pollution.

[0035] In the embodiments of this utility model, reference is made to Figure 3 As shown, the hot air hole 14 is truncated cone in shape, and the size of the end of the hot air hole 14 facing the inside of the drying oven 1 is smaller than the size of the other end of the hot air hole 14.

[0036] It should be noted that by setting the hot air hole 14 with a smaller outer diameter and a larger inner diameter, the flow rate of the hot air flowing out of the hot air hole 14 can be effectively increased. The high-speed hot air facilitates the drying and dehydration of the waste residue, thereby improving the efficiency of drying and dehydrating the waste residue.

[0037] In the embodiments of this utility model, reference is made to Figure 3 , Figure 4 , Figure 5 As shown, the outer surface of the first rotating shaft 16 is sleeved on one end of the first limiting cylinder 17, and the outer surface of the other end of the first limiting cylinder 17 is rotatably connected to the inner wall of the first limiting groove 23. The first limiting groove 23 is disposed on the side of the first support plate 18. The outer surface of the second rotating shaft 20 is sleeved on one end of the second limiting cylinder 21, and the outer surface of the other end of the second limiting cylinder 21 is rotatably connected to the inner wall of the second limiting groove 24. The second limiting groove 24 is disposed on the side of the second support plate 22.

[0038] It should be noted that by setting the first limiting cylinder 17 and the first limiting groove 23, and the second limiting cylinder 21 and the second limiting groove 24, the stability of the drying oven 1 when rotating back and forth can be improved by the guidance of the first limiting groove 23 and the second limiting groove 24.

[0039] The working principle of the waste residue drying equipment for concentrated brine treatment provided by this utility model is as follows:

[0040] By setting a drying chamber 1 with a top opening, waste residue can be fed into the heat transfer plate 25 inside the drying chamber 1 using an existing feeding device. An electric heating plate 26 is set below the heat transfer plate 25, which heats the heat transfer plate 25, thereby increasing its temperature and enabling the waste residue to be dried and dehydrated. Furthermore, the heat transfer plate 25 acts as an insulator, preventing the electric heating plate 26 from directly contacting the waste residue, which could cause the waste residue to stick to the electric heating plate 26, resulting in contamination and damage, affecting subsequent use. Hot air holes 14 are provided, allowing heat to diffuse outwards when the electric heating plate 26 is heating. Hot air can be delivered through the air outlet 27 and the exhaust fan 28 to the area above the heat transfer plate 25, working in conjunction with the heat transfer plate 25 to dry the waste residue, effectively improving the drying effect.

[0041] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0042] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
