Description

Technical Field

[0001] The present application relates to the technical field of thermal oxidation of waste salt, and in particular to a feeding device for a thermal oxidation treatment system of waste salt. Background Art

[0002] Industrial waste salt refers to waste salt substances generated during industrial production. These waste salts are usually caused by by-products in the process, wastewater treatment, waste liquid treatment, etc. The composition and properties of industrial waste salts depend on different industrial production processes and may include compounds such as chlorides, sulfates, nitrates, carbonates, etc.

[0003] There are three main methods for dry disposal of industrial waste salt, namely incineration, high-temperature melting, and organic matter pyrolysis and carbonization technology. Incineration is usually achieved using a thermal oxidation rotary kiln. However, before transporting the waste salt to the rotary kiln, the waste salt needs to be cooled to ensure that it reaches a safe temperature. If the temperature of the waste salt is too high, the solubility of harmful substances in the waste salt will increase, which is not conducive to subsequent treatment. Therefore, a device for cooling the waste salt is required.

[0004] The Chinese patent with the announcement number CN221395637U discloses a feeding device for a waste salt thermal oxidation treatment system, which includes a horizontal base, a water outlet pipe with a solenoid valve, a bearing seat, a vertical feed pipe for waste salt material, a flange interface, a rotating shaft, a spiral feed tooth and a coupling, etc. The beneficial effects of this patent are: the improved design of the horizontal installation component, the flange interface, the rotating shaft, the spiral feed tooth and the coupling, which adopts a modular and simplified reasonable structural design as a whole, realizes rapid rotary feeding, and has a long service life, low manufacturing cost, and is also easy to dismantle and maintain; both ends of the spiral feed tooth are installed with a circular internal thread fixing plate and a locking nut, and the spiral feed tooth and the circular internal thread fixing plate constitute a modular structure, which is convenient for the replacement or maintenance of the spiral feed tooth after wear, and the horizontal installation component is used to complete the rapid assembly of the hollow sealing box.

[0005] With respect to the above-mentioned related technologies, the prior art utilizes cold water to fill a hollow sealed box, so that the waste salt in the circular feeding cavity undergoes heat exchange, and cooperates with spiral feeding teeth to achieve the purpose of cooling and conveying the waste salt. However, such a setting has disadvantages. First, when the waste salt is conveyed by spiral feeding teeth, the spiral feeding teeth will stir and shear the waste salt, which can break up larger waste salt blocks, but it also increases the friction between the waste salt and the spiral feeding teeth, which causes frictional heating and offsets the heat exchange of the cold water. Secondly, the hollow sealed box is filled with cold water, but in the actual cooling process, only the cold water near the spiral feeding teeth exchanges heat with the waste salt, and the rest of the cold water stays in the hollow sealed box for a short time and does not participate in the heat exchange. It takes more time to fill the hollow sealed box with cold water, which prolongs the cooling time of the waste salt. Both disadvantages reduce the cooling efficiency of the feeding device. Summary of the invention

[0006] In order to improve the cooling efficiency of a feeding device, the present application provides a feeding device for a waste salt thermal oxidation treatment system.

[0007] The present application provides a feeding device for a waste salt thermal oxidation treatment system using the following technical solution:

[0008] A feeding device for a waste salt thermal oxidation treatment system comprises a machine body and a conveying pipe, wherein the machine body is provided with a feed end and a discharge end, the conveying pipe is rotatably connected in the machine body, the conveying pipe is arranged obliquely, and the height of the conveying pipe gradually decreases from the feed end to the discharge end as a reference direction, a feed pipe is installed between the feed end and the conveying pipe, a rotating part for driving the conveying pipe to rotate is arranged on the machine body, a water inlet pipe and a cooling pipe are arranged on the machine body, the water inlet pipe is connected with the cooling pipe, the conveying pipe passes through the cooling pipe, a cooling component for accelerating the cooling of the waste salt is arranged on the water inlet pipe, a water outlet pipe is arranged at the lowest point of the cooling pipe, a cooling box is arranged below the machine body, the water outlet pipe is connected with the cooling box, a water pump is arranged on one side of the cooling box, and the water pump is connected between the cooling box and the water inlet pipe.

[0009] By adopting the above technical solution, during cooling, the waste salt enters the delivery pipe through the feed pipe, and the delivery pipe is rotated through the rotating part, and cold water enters the cooling pipe through the water inlet pipe. Due to centrifugal force and gravity, the waste salt moves along the inner wall of the rotating delivery pipe, and the cold water and the delivery pipe are heat-exchanged to achieve the effect of transporting and cooling the waste salt. The cooling water after the heat exchange enters the cooling box for natural cooling, and is then re-delivered to the water inlet pipe by the water pump to circulate the heat exchange of the waste salt. Since the inside of the delivery pipe is hollow, the shearing phenomenon of the waste salt is reduced, ensuring that the waste salt is only heat-exchanged. The cooling water moves in the cooling pipe and is close to the delivery pipe, so that the cooling water can heat-exchange with the delivery pipe at any time. Compared with the prior art, on the one hand, the phenomenon of waste salt being sheared and heated is reduced, and on the other hand, the cooling water can quickly fill the cooling pipe and heat-exchange with the delivery pipe, shortening the filling time of the cooling pipe, thereby shortening the cooling time of the waste salt and improving the cooling efficiency of the feeding device.

[0010] Optionally, the feed pipe is passed through the machine body, a temporary storage box and an auxiliary support block are connected to the machine body, the temporary storage box is connected to the bottom end of the feed pipe, the bottom wall of the temporary storage box is opened and fits the surface of the conveying pipe, the auxiliary support block fits the surface of the conveying pipe and contacts the temporary storage box, and a plurality of feed holes are opened on the conveying pipe at positions corresponding to the temporary storage box.

[0011] By adopting the above technical solution, when feeding, the waste salt falls into the temporary storage box through the feeding pipe and accumulates. As the conveying pipe rotates, the waste salt enters the conveying pipe through the feeding hole, thereby achieving the effect of waste salt transportation.

[0012] Optionally, a dredging assembly is provided on the machine body, and the dredging assembly includes a rotating disk, a swing rod, a rotating motor and a moving rod, a bellows is installed between the feed pipe and the temporary storage box, a rubber ring is installed between the feed pipe and the machine body, the moving rod is slidably fitted on the machine body, a collision block is connected to the end of the moving rod, a rubber block is connected to the mounting tube, a mounting frame is connected to the machine body, the rotating disk and the swing rod are both rotatably connected to the mounting frame, the bottom end of the swing rod is fan-shaped and connected to a plurality of driving teeth, a plurality of fixed teeth are connected to the moving rod, the driving teeth are meshed with the fixed teeth, the rotating disk is connected to a driving block, a swing groove is opened on the swing rod, the driving block is slidably fitted in the swing groove, and the rotating motor is installed on the mounting frame and coaxially connected to the rotating disk.

[0013] By adopting the above technical solution, since the feed hole is small and the conveying pipe remains in a rotating state, the waste salt cannot directly enter the conveying pipe and will accumulate in the temporary storage box and the feed pipe. If the time becomes longer, it is easy to block the feed pipe. When dredging, start the rotating motor to rotate the rotating disk, drive the driving block to rotate, and drive the swing rod to swing through the cooperation of the driving block and the swing groove, and then cooperate with the driving teeth and the fixed teeth to drive the moving rod to move, so that the collision block hits the rubber block, and the feed pipe vibrates, thereby shaking off the waste salt and achieving the effect of dredging the feed pipe. The driving block drives the swing rod to swing, but when the driving block approaches the rotation center of the swing rod, the swing amplitude becomes smaller, which will cause the swing rod to swing with acceleration. In this way, the moving rod moves with acceleration, causing the collision block to hit the rubber block with acceleration, which will generate a large impact force, and cooperate with the rubber block buffer to make the feed pipe vibrate but does not affect the overall installation of the feed pipe.

[0014] Optionally, a cooling cylinder is connected to the surface of the feed pipe, a water guide pipe is connected between the water inlet pipe and the cooling cylinder, a water guide plate is connected to the water inlet end of the water guide pipe, and the cooling cylinder is connected to the cooling pipe.

[0015] By adopting the above technical solution, the cooling cylinder is used for preliminary heat exchange of the waste salt accumulated in the feed pipe, so that the waste salt is initially cooled, thereby improving the cooling efficiency of the waste salt.

[0016] Optionally, the cooling component includes a holding container, a hydraulic cylinder, a fixed bracket, a grinding plate, a grinding motor and a sweeping plate, the holding container is connected to one side of the water inlet pipe, an ice pouring port is provided on one side of the holding container, the bottom end of the holding container is tilted, the lowest point of the bottom end of the holding container is close to the water inlet pipe, ice cubes are poured into the holding container, the fixed bracket is connected to the machine body, the grinding plate is rotatably connected to the fixed bracket, the grinding plate is a circular plate, a gap is left between the grinding plate and the bottom end of the holding container, a plurality of grinding flanges are provided on the grinding plate, The fixed bracket is connected to a panel matching the shape of the grinding plate, the panel fits the edge of the grinding plate, the grinding motor is connected to the fixed bracket and is coaxially connected to the grinding plate, the hydraulic cylinder is connected to the top of the containing container, the output end of the hydraulic cylinder is connected to a pressure plate, the pressure plate moves in the containing container, an ice entry notch is opened on the water inlet pipe, the grinding plate is partially located in the ice entry notch, the sweeping plate is connected to one side of the ice entry notch and is located above the grinding plate, the sweeping plate is connected to bristles, and the bristles abut against the grinding plate.

[0017] By adopting the above technical solution, since the cooling water is circulated through the water delivery pump and the cooling water relies on the cooling box to cool naturally, the cooling speed is slow. With long-term use, the overall temperature of the cooling water increases, and there is a phenomenon that the cooling rate of the waste salt decreases. When the temperature is further reduced, the grinding motor and the hydraulic cylinder are started, so that the pressure plate applies pressure to the ice cubes in the container, the grinding plate rotates, and the grinding flange grinds the lowest ice cubes to become ice slag. The ice slag is restricted by the bristles when it moves, and enters the water inlet pipe until it falls into the cooling pipe and merges with the cooling water to achieve the effect of cooling the cooling water.

[0018] Optionally, a limited discharge component is provided at the discharge end of the conveying pipe, and the limited discharge component includes a fixed box and a rotating plate, the fixed box is connected to the machine body, the fixed box is hollow and has a material passage, the rotating plate is rotatably connected in the fixed box, the rotating plate has a fast discharge groove and a plurality of slow discharge holes, and the fixed box is provided with a limiting component that limits the rotation of the rotating plate.

[0019] By adopting the above technical solution, quantitative operation is required during thermal oxidation of waste salt, and the transportation of waste salt needs to be temporarily stopped after a certain amount of waste salt is transported. When limiting the transportation, the operator rotates the rotating plate to block the feed port to prevent the movement of waste salt and achieve the effect of limiting the discharge of waste salt. The operator can also align the fast discharge slot or slow discharge hole with the feed port according to actual needs to adjust the delivery amount of waste salt, so that the waste salt transportation is more in line with the actual thermal oxidation needs.

[0020] Optionally, the limiting assembly includes a connecting block, a toggle column, a limiting column and a pressure spring, two connecting blocks are provided, and both are connected to the arc surface of the rotating plate, an arc avoidance groove is opened at the position of the fixed box corresponding to the connecting block, a fixed block is connected to the toggle column, the fixed block is slidably fitted on the connecting block, the pressure spring is installed between the connecting block and the fixed block, a limiting hole is opened at the bottom end of the toggle column, three limiting columns are provided, and both are connected to the arc surface of the fixed box, one limiting column corresponds to the fast-discharge groove, one limiting column corresponds to the slow-discharge hole, and the remaining limiting column corresponds to the solid area of ​​the rotating plate, and when the rotating plate is limited, the limiting column is located in the limiting hole.

[0021] By adopting the above technical solution, when adjusting the waste salt discharge volume, pull the toggle column to toggle the rotating plate to rotate until the rotating plate rotates to a specified angle, release the toggle column, and the toggle column moves under the action of the pressure spring, causing the limiting column to enter the limiting hole, thereby limiting the movement of the toggle column and achieving the effect of limiting the rotation of the rotating plate.

[0022] Optionally, a maintenance door and an opening and closing assembly are provided on the machine body, and the opening and closing assembly includes a rotating screw, a moving block, a limiting rail and a sliding block.

The distance between the rotating screw and the fixed rail gradually decreases. The limiting rail is connected to the machine body and is parallel to the rotating screw. The moving block is threadedly fitted on the rotating screw and slidably fitted with the limiting rail. The connecting column is rotatably connected to the sliding block.

[0023] By adopting the above technical solution, when opening and closing the maintenance door, the screw is rotated to move the moving block, and the sliding block is driven to move through the connecting column. At the same time, as the height of the moving block rises, the maintenance door is opened, thereby achieving the effect of opening and closing the maintenance door.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. During cooling, the waste salt enters the delivery pipe through the feed pipe, and the delivery pipe is rotated by the rotating parts. At the same time, cold water enters the cooling pipe through the water inlet pipe. Due to centrifugal force and gravity, the waste salt moves along the inner wall of the rotating delivery pipe, and the cold water and the delivery pipe are heat exchanged to achieve the effect of transporting and cooling the waste salt. The cooling water after the heat exchange enters the cooling box for natural cooling, and is then re-delivered to the water inlet pipe by the water pump to circulate the heat exchange of the waste salt. Since the inside of the delivery pipe is hollow, the shearing phenomenon of the waste salt is reduced, ensuring that the waste salt is only heat exchanged. The cooling water moves in the cooling pipe and is close to the delivery pipe, so that the cooling water can heat exchange with the delivery pipe at any time. Compared with the existing technology, on the one hand, the phenomenon of waste salt being sheared and heated is reduced, and on the other hand, the cooling water can quickly fill the cooling pipe and heat exchange with the delivery pipe, shortening the filling time of the cooling pipe, thereby shortening the cooling time of the waste salt and improving the cooling efficiency of the feeding device;

[0026] 2. When unblocking, start the rotating motor to rotate the rotating disk, drive the driving block to rotate, and drive the swing rod to swing through the cooperation of the driving block and the swing slot, and then drive the moving rod to move with the cooperation of the driving teeth and the fixed teeth, so that the collision block hits the rubber block and the feed pipe vibrates, thereby shaking off the waste salt and unblocking the feed pipe. The driving block drives the swing rod to swing, but when the driving block approaches the rotation center of the swing rod, the swing amplitude becomes smaller, which causes the swing rod to swing with acceleration. In this way, the moving rod moves with acceleration, causing the collision block to hit the rubber block with acceleration, which will generate a large impact force, and cooperate with the rubber block for buffering, so that the feed pipe vibrates but does not affect the overall installation of the feed pipe;

[0027] 3. When the temperature drops further, start the grinding motor and hydraulic cylinder to make the pressure plate pressurize the ice in the container, the grinding plate rotates, and the grinding flange grinds the lowest ice to form ice chips. The ice chips are restricted by the bristles when moving and enter the water inlet pipe until they fall into the cooling pipe and merge with the cooling water to achieve the effect of cooling the cooling water.

One end of the sweeping plate 86 is fixedly connected to one side of the ice entry notch 131, and a plurality of bristles 861 are fixedly connected to the sweeping plate 86, and the bristles 861 abut against the surface of the grinding plate 84. An L-plate 132 is fixedly connected to the position of the water inlet pipe 13 near the ice inlet notch 131, and the L-plate 132 shields the ice inlet notch 131. The L-plate 132 is used to prevent cooling water from leaking from the ice inlet notch 131.

[0054] When cooling the cooling water, pour the ice cubes into the container 81 from the ice pouring port 811, start the hydraulic cylinder 82, and the pressure plate 821 descends to apply pressure to the ice cubes. At the same time, start the grinding motor 85 to rotate the grinding plate 84, and the grinding flange grinds the ice cubes at the lowest point to form ice debris. The moving ice debris is blocked by the bristles 861, and the ice debris moves along the direction of the sweeping plate 86, falls into the cooling pipe 14 through the water inlet pipe 13, and merges with the cooling water to achieve the cooling water effect and ensure the cooling rate of the waste salt.

[0055] The implementation principle of a feeding device for a waste salt thermal oxidation treatment system in an embodiment of the present application is as follows: when cooling, the waste salt is poured into the feed pipe 6, the rotating part 12 is started, the conveying pipe 2 is rotated, the waste salt enters the conveying pipe 2 through the feed port, and moves along the conveying pipe 2, and at the same time the water pump 16 is started, the cooling water enters the cooling cylinder 65 and the cooling pipe 14 through the water inlet pipe 13, so that the waste salt undergoes two heat exchanges, the cooling water is re-delivered by the water pump 16 through the cooling box 15 to repeatedly cool the waste salt, and finally discharged through the fixed box 41 and the rotating plate 42, thereby achieving the effect of conveying and cooling the waste salt.

[0056] Since the interior of the conveying pipe 2 is hollow, the shearing phenomenon of the waste salt is reduced, ensuring that the waste salt only undergoes heat exchange. The cooling water moves in the cooling pipe 14 and is close to the conveying pipe 2, so that the cooling water can exchange heat with the conveying pipe 2 at any time. Compared with the prior art, on the one hand, the phenomenon of waste salt being sheared and heated is reduced, and on the other hand, the cooling water can quickly fill the cooling pipe 14 and exchange heat with the conveying pipe 2, shortening the filling time of the cooling pipe 14, thereby shortening the cooling time of the waste salt and improving the cooling efficiency of the feeding device.

[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
