Description

Technical Field

[0001] This utility model relates to the field of horizontal screw centrifuge technology, and in particular to a horizontal screw centrifuge based on sediment conveying technology. Background Technology

[0002] A horizontal screw centrifuge is a mechanical device that uses the principle of centrifugal sedimentation to achieve solid-liquid separation. It is widely used in environmental protection, chemical, pharmaceutical, and food industries. It mainly consists of a drum, a screw conveyor, and a differential gear. The high-speed rotation of the drum generates centrifugal force, causing solid particles in the suspension to adhere to the wall to form a solid ring layer, while the liquid forms a liquid ring layer. The screw conveyor rotates at a speed slightly lower than that of the drum, pushing the solid ring layer of sludge towards the conical end of the drum for discharge, while the liquid ring layer of liquid is discharged through the overflow port.

[0003] The existing technical solutions have the following shortcomings:

[0004] As a highly efficient solid-liquid separation device, the operational stability of a decanter centrifuge directly affects the smoothness of the entire production line. However, in actual operation, the separated sludge often exhibits characteristics of large quantity and relatively viscous texture. Without effective guidance and diversion, this sludge will rush directly to the discharge port in a relatively concentrated manner. This instantaneous discharge of a large amount of sludge can easily cause the material accumulation rate at the discharge port to exceed its discharge capacity, ultimately leading to blockage. Once the discharge port is blocked, it will not only directly affect the normal sludge discharge function of the decanter centrifuge, preventing the separated sludge from being discharged in time and thus affecting the separation efficiency of the equipment, but may also increase the operating load of the equipment due to increased internal pressure, or even cause equipment failure, requiring shutdown for cleaning and maintenance. This will not only interrupt the production process and reduce production efficiency, but also increase labor costs and equipment maintenance costs, adversely affecting the normal production and operation of the enterprise.

[0005] Therefore, we need to design a horizontal screw centrifuge based on sludge conveying technology to solve the problems mentioned above. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the defect that the sludge discharge pipe of the existing horizontal screw centrifuge is prone to blockage. This utility model proposes a horizontal screw centrifuge based on sludge conveying technology.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a horizontal screw centrifuge based on sludge conveying technology, including a horizontal screw centrifuge body, an organic cover connected to the top of the horizontal screw centrifuge body, a drive motor assembly connected to one side of the horizontal screw centrifuge body, and a sludge discharge pipe fixed to the bottom of the horizontal screw centrifuge body, and the interior of the sludge discharge pipe is divided into a slow flow area and a crushing area.

[0008] Preferably, the slow-flow area is fixed with a flow divider seat, and the flow divider seat is provided with nine sets of partition plates inside.

[0009] Preferably, the partition plate is wavy in shape and is arranged at equal intervals inside the diversion seat.

[0010] Preferably, the crushing area is rotatably connected to a second connecting shaft and a first connecting shaft, and crushing rollers are fixed to the outer sides of both the second connecting shaft and the first connecting shaft. A motor body is fixed to the rear of the sludge discharge pipe. A first gear is fixed to the outer side of the second connecting shaft, and a second gear is fixed to the outer side of the second gear. The second gear and the first gear are meshed together. The output end of the motor body is connected to the second connecting shaft.

[0011] Preferably, a rotating shaft is rotatably connected below both the second connecting shaft and the first connecting shaft, and two sets of rotating shafts are provided accordingly. A cleaning kit is fixed to the outside of each rotating shaft, and the second connecting shaft and the first connecting shaft are connected to the rotating shaft via pulleys.

[0012] Preferably, the outer side of the cleaning kit comes into contact with and rubs against the outer side of the pulverizing roller.

[0013] Compared with the prior art, the beneficial effects of this utility model include:

[0014] 1. By setting the partition plate in a wave shape, the flow rate of the sludge can be slowed down. Firstly, it can effectively prevent the sludge from accumulating in a large amount in a short period of time and falling directly into the sludge discharge pipe, thereby greatly reducing the possibility of blockage in the sludge discharge pipe. Once the sludge discharge pipe is blocked, it will not only affect the normal operation of the entire system, but may also require a lot of time and effort to clean and repair, causing unnecessary trouble and losses. On the other hand, this slowing effect can also prevent a large amount of sludge from violently hitting the crushing blades in the crushing structure below under the action of gravity, which would cause great impact and wear on the blades. Over time, this may lead to blade deformation and damage, and even affect the overall operational stability of the crushing structure, making it difficult for it to complete the crushing work smoothly according to the preset efficiency and effect.

[0015] 2. By precisely installing a dedicated cleaning component directly below the crushing roller, this design cleverly achieves the dual effect of simultaneous crushing and cleaning. Specifically, when the crushing roller operates at high speed to crush the sludge, the cleaning component below it will be activated to thoroughly clean the outer surface of the crushing roller. While the crushing operation is underway, the sludge adhering to the outside of the crushing roller is promptly removed and guided to the designated collection area, ensuring that every piece of crushed sludge can be effectively utilized. This avoids resource waste caused by sludge residue and, in the long run, can significantly reduce resource costs in the production process and improve overall production efficiency.

[0022] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0023] To address the technical problem of easy clogging at the sludge discharge pipe of existing horizontal screw centrifuges, the following solution is disclosed, as follows: Figures 1-4 As shown:

[0024] A horizontal screw centrifuge based on sludge conveying technology includes a horizontal screw centrifuge body 3, an organic cover 1 connected to the top of the horizontal screw centrifuge body 3, a drive motor assembly 2 connected to one side of the horizontal screw centrifuge body 3, and a sludge discharge pipe 4 fixed to the bottom of the horizontal screw centrifuge body 3. The interior of the sludge discharge pipe 4 is divided into a slow flow area and a crushing area.

[0025] Specifically, such as Figure 1 and Figure 2 As shown, by utilizing the slow-flow zone and the crushing zone, the flow rate of the sludge can be slowed down while the sludge is crushed at the same time. This not only prevents blockage at the four points of the sludge discharge pipe, but also brings convenience to the subsequent sludge treatment.

[0026] The slow-flow area is fixed with a flow divider seat 5, and the interior of the flow divider seat 5 is provided with nine sets of partition plates 6;

[0027] The partition plate 6 is wavy in shape and is arranged at equal intervals inside the diversion seat 5;

[0028] Specifically, such as Figure 2 As shown, the partition plate 6 is set in a corrugated shape, which allows the sediment to continuously consume its own kinetic energy during the flow process, thereby naturally slowing down the flow rate and creating more favorable conditions for the subsequent further processing or transportation of the sediment.

[0029] The crushing area is rotatably connected to the second connecting shaft 13 and the first connecting shaft 12, and crushing rollers 7 are fixed on the outer side of the second connecting shaft 13 and the first connecting shaft 12. The motor body 9 is fixed at the rear of the sludge discharge pipe 4. The first gear 10 is fixed on the outer side of the second connecting shaft 13, and the second gear 11 is fixed on the outer side of the second gear 11. The second gear 11 and the first gear 10 are meshed and connected. The output end of the motor body 9 is connected to the second connecting shaft 13.

[0030] The second connecting shaft 13 and the first connecting shaft 12 are both rotatably connected to the lower part of the rotating shaft 15, and two sets of rotating shaft 15 are provided accordingly. The outer side of the rotating shaft 15 is fixed with a cleaning kit 8. The second connecting shaft 13 and the first connecting shaft 12 are connected to the rotating shaft 15 through a pulley 14.

[0031] The outer side of the cleaning kit 8 comes into contact with and rubs against the outer side of the crushing roller 7;

[0032] Specifically, such as Figure 3 , Figure 4 As shown, the crushing roller can be used to crush the sediment, which is convenient for subsequent processing. At the same time, a cleaning component is provided to clean the sediment adhering to the surface of the crushing roller 7, preventing waste of resources.

[0033] In this embodiment, during use, the horizontal screw centrifuge continuously introduces the material into the inner cylinder of the clinker screw through the feed pipe. After acceleration, the material enters the drum. Under the action of centrifugal force, the heavier solids are deposited on the drum wall to form a sludge layer. The conveying screw continuously pushes the deposited solids to the cone end of the drum and discharges them out of the machine through the sludge discharge port. The lighter liquids form an inner liquid ring and continuously overflow from the large end overflow port of the drum and are discharged out of the machine through the liquid discharge port.

[0034] When the sediment enters the sediment discharge pipe 4, it passes through the diverter seat 5 and the partition plate 6, which slows down its flow rate. After passing through the crushing area, the motor body 9 drives the second connecting shaft 13 to rotate. Under the meshing connection of the first gear 10 and the second gear 11, the two sets of crushing rollers can rotate in opposite directions, thereby further crushing the sediment and bringing convenience to the subsequent sediment processing work. While the second connecting shaft 13 and the first connecting shaft 12 are rotating, they are connected by the pulley 14, which can drive the cleaning kit 8 below to rotate synchronously, thus realizing the function of crushing and cleaning at the same time.

[0035] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
