Description

Technical Field

[0001] This utility model relates to the field of horizontal screw centrifuge technology, and in particular to an anti-clogging discharge port for a horizontal screw centrifuge. Background Technology

[0002] A horizontal screw centrifuge is a solid-liquid separation device that uses a high-speed rotating drum to generate centrifugal force, separating solid particles from a liquid. An internal screw conveyor pushes the solid material to the discharge port, where wet sludge is discharged. The clean liquid is discharged from the other side, ensuring efficient operation of the equipment.

[0003] Utility model CN205887197U discloses a horizontal decanter centrifuge, the key technical points of which are: a frame, a cover fixed to the frame, a rotating drum inside the cover, a screw conveyor, and a feed pipe; the rotating drum has a solid phase discharge port in the drying zone and a liquid phase discharge port in the settling zone, and multiple feed ports are provided on the side wall of the feed pipe; the screw conveyor includes a main body and screw blades, with a material inlet on the main body and through holes on the screw blades located in the settling zone; in every pair of screw blades, the radial diameter of the through hole on the screw blade closer to the material inlet is smaller than the radial diameter of the through hole on the screw blade farther from the material inlet. By improving the screw blade structure in the horizontal decanter centrifuge, the flow of liquid phase is increased, foam formation is reduced, and the solid-liquid separation effect is not affected; multiple spiral grooves are provided on the inner wall of the feed pipe.

[0004] Regarding the above-mentioned content, the following technical defects exist: A horizontal screw centrifuge is a device used for solid-liquid separation, commonly used to treat liquids containing suspended solids. It uses a high-speed rotating drum to generate centrifugal force, separating the residue from the liquid. The residue is discharged from the centrifuge's slag discharge port, and the liquid is discharged from the drain port. Typically, during use, the feed pipe for the liquid to be treated is connected to the feed pipe, allowing the liquid to be transported into the drum. Through the movement of the centrifuge and the drum, the liquid can be separated. However, when continuously processing large quantities of liquid, the slag discharge port lacks an anti-clogging system, leading to blockage. A blocked slag discharge port cannot discharge residue in a timely manner, resulting in solid accumulation inside the centrifuge, reducing separation efficiency. Excessive solid matter inside the drum affects the liquid's flowability, thus worsening the solid-liquid separation effect and impacting the centrifuge's performance. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology that when a large amount of liquid to be processed is continuously processed, the slag discharge port itself does not have an anti-clogging system, and the slag discharge port will become blocked. The blocked slag discharge port cannot discharge the residue in time, which will lead to the accumulation of solids inside the centrifuge, reduce the separation efficiency, and when there is too much solid matter in the drum, it will affect the fluidity of the liquid, thereby reducing the solid-liquid separation effect and affecting the use of the centrifuge.

[0006] To solve the above-mentioned technical problems, this utility model provides an anti-clogging horizontal screw centrifuge discharge port, comprising: a centrifuge body, a rotating drum installed on the inner wall of the centrifuge body, a cover installed on one side of the centrifuge body corresponding to the rotating drum, a feed pipe installed at one end of the centrifuge body, a discharge port body opened on one side of the centrifuge body, a sludge discharge port opened on the side of the centrifuge body near the discharge port body, an adjusting mechanism provided on one side of the discharge port body, the adjusting mechanism including a fixing block, the fixing block being fixedly connected to one side of the discharge port body, a motor being fixedly connected to one side of the fixing block, a power rod being fixedly connected to the output end of the motor, and the arc surface of the power rod having threads with opposite thread directions. The power rod has two cleaning plates threadedly connected to its arc surface. An adjusting block is fixedly connected to one side of each cleaning plate, and an abutment rod is fixedly connected to one side of each adjusting block. A steel rope is fixedly connected to one end of the arc surface of each of the two abutment rods. A rotating shaft is wound around the arc surface of the steel rope. Two support rods are rotatably connected to the arc surface of the rotating shaft. One end of the arc surface of each of the two support rods is fixedly connected to both sides of the inner wall of the drain outlet. A coil spring is fitted onto one end of the arc surface of the rotating shaft. The two ends of the arc surface of the coil spring are fixedly connected to the rotating shaft and one side of each of the two support rods. An adjusting cylinder is fixedly connected to the other end of the arc surface of the rotating shaft. Several stirring blades are fixedly connected to the arc surface of the adjusting cylinder, and the stirring blades are evenly distributed on the adjusting cylinder.

[0007] The aforementioned components achieve the following effect: The horizontal screw centrifuge body is a device used for solid-liquid separation, commonly used to treat liquids containing suspended solids. It generates centrifugal force through a high-speed rotating drum, separating the residue from the liquid. The residue is discharged from the slag outlet of the centrifuge body, and the liquid is discharged from the drain outlet. Typically, during use, the feed pipe and inlet pipe of the liquid to be treated are connected, allowing the liquid to be transported into the drum. Through the movement of the centrifuge body and the drum, the liquid can be separated. However, the slag outlet of the centrifuge body faces challenges when continuously processing large quantities of liquids. When liquids are present, the discharge port itself lacks an anti-clogging system, leading to blockage. A blocked discharge port cannot discharge residue in a timely manner, resulting in solid accumulation inside the centrifuge body, reducing separation efficiency. Excessive solid matter inside the drum affects the fluidity of the liquid, thus worsening the solid-liquid separation effect and impacting the centrifuge's performance. In such cases, an adjustment mechanism can be used to clean and guide the residue accumulated on the surface of the discharge port, thereby improving the discharge efficiency and separation efficiency of the centrifuge body.

[0008] Preferably, the inner walls of the two cleaning plates are slidably connected by the same guide rod, and both ends of the arc surface of the guide rod are fixedly connected to one side of the slag discharge port body.

[0009] The effect achieved by the above components is that the guide rod can improve the stability of the two cleaning plates during movement.

[0010] Preferably, an abutment block is fixedly connected to one side of the adjusting block.

[0011] The effect achieved by the above components is that the abutment block can improve the stability of the contact between the adjusting block and the filter screen inside the slag discharge port body, and reduce the friction generated by the contact.

[0012] Preferably, the stirring blade is arc-shaped.

[0013] The effect achieved by the above components is that the arc-shaped stirring blades can better stir the residue and improve the stirring effect of the residue.

[0014] Preferably, the arc surface of the feed pipe is provided with an auxiliary mechanism, the auxiliary mechanism including a sleeve, the sleeve being rotatably connected to the arc surface of the feed pipe, an adjusting pipe being fixedly connected to one side of the sleeve, a positioning hole being provided on the arc surface of the sleeve, and a rotating rod being threaded through the inner wall of the positioning hole.

[0015] The effect achieved by the above components is that when the liquid to be processed is connected to the feed pipe through the delivery pipe, the angle of the feed pipe can be adjusted according to the auxiliary mechanism, thereby improving the stability of the connection between the delivery pipe and the feed pipe and avoiding the effect of the connection between the two pipes due to excessive deviation of the connection angle.

[0016] Preferably, the arc surface of the rotating rod is provided with a plurality of auxiliary grooves, and the plurality of auxiliary grooves are evenly distributed on the rotating rod.

[0019] The effect achieved by the above components is that the marking block makes it easier for workers to adjust the angle of the adjusting rod, thus improving the accuracy of the adjustment.

[0020] Compared with related technologies, the anti-clogging discharge port of the horizontal screw centrifuge provided by this utility model has the following beneficial effects:

Detailed Implementation

[0030] 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.

[0031] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0032] Please see Figures 1 to 6 The present invention provides an anti-clogging horizontal screw centrifuge slag discharge port, comprising: a centrifuge body 1, a rotating drum 4 installed on the inner wall of the centrifuge body 1, a cover 5 installed on one side of the centrifuge body 1 corresponding to the rotating drum 4, a feed pipe 6 installed at one end of the centrifuge body 1, a slag discharge port body 7 opened on one side of the centrifuge body 1, a sewage discharge port 8 opened on the side of the centrifuge body 1 near the slag discharge port body 7, an adjustment mechanism 2 provided on one side of the slag discharge port body 7, and an auxiliary mechanism 3 provided on the arc surface of the feed pipe 6.

[0033] In the embodiments of this utility model, please refer to Figures 3 to 5The adjusting mechanism 2 includes a fixed block 201, which is fixedly connected to one side of the slag discharge port body 7. A motor 202 is fixedly connected to one side of the fixed block 201. A power rod 203 is fixedly connected to the output end of the motor 202. The arc surface of the power rod 203 has threads with opposite directions. Two cleaning plates 204 are threaded to the arc surface of the power rod 203. An adjusting block 206 is fixedly connected to one side of the cleaning plate 204. An abutment rod 207 is fixedly connected to one side of the adjusting block 206. The same steel rope 208 is fixedly connected to one end of the arc surface of the two abutment rods 207. A rotating shaft 210 is wound around the arc surface of the steel rope 208. Two support rods 209 are rotatably connected to the arc surface of the rotating shaft 210. One end of the arc surface of 09 is fixedly connected to both sides of the inner wall of the drain port 8. One end of the arc surface of the rotating shaft 210 is fitted with a coil spring 213. The two ends of the arc surface of the coil spring 213 are fixedly connected to the rotating shaft 210 and one side of the two support rods 209, respectively. The other end of the arc surface of the rotating shaft 210 is fixedly connected to an adjusting cylinder 211. Several stirring blades 212 are fixedly connected to the arc surface of the adjusting cylinder 211. Several stirring blades 212 are evenly distributed on the adjusting cylinder 211. The horizontal screw centrifuge body 1 is a device used for solid-liquid separation. It is often used to treat liquids containing suspended solids. It generates centrifugal force through the high-speed rotating drum 4 to separate the residue in the liquid. The residue will be discharged from the slag discharge port body 7 of the centrifuge body 1, and the liquid will be discharged from the slag discharge port body 7. The waste outlet 8 discharges liquid. Normally, during operation, the liquid delivery pipe is connected to the feed pipe 6, allowing the liquid to be transported to the drum 4. The liquid is then separated by the movement of the centrifuge body 1 and the drum 4. However, when continuously processing large quantities of liquid, the slag discharge outlet 7 lacks an anti-clogging system, leading to blockages. A blocked outlet 7 cannot promptly discharge residue, resulting in solid accumulation inside the centrifuge body 1 and reduced separation efficiency. Excessive solids in the drum 4 also affect liquid flow, further impairing solid-liquid separation and impacting the centrifuge body 1's performance. In such cases, the slag discharge can be adjusted via the regulating mechanism 2. The residue accumulated on the surface of the discharge port body 7 is cleaned and guided, thereby improving the slag discharge effect of the discharge port body 7 and the separation efficiency of the centrifuge body 1 through the adjustment mechanism 2. The inner walls of the two cleaning plates 204 are slidably connected to the same guide rod 205. Both ends of the arc surface of the guide rod 205 are fixedly connected to one side of the discharge port body 7. The guide rod 205 can improve the stability of the movement of the two cleaning plates 204. One side of the adjustment block 206 is fixedly connected to the abutment block 214. The abutment block 214 can improve the stability of the contact between the adjustment block 206 and the filter screen inside the discharge port body 7 and reduce the friction generated by the contact. The stirring blade 212 is arc-shaped. The arc-shaped stirring blade 212 can better stir the residue and improve the stirring effect of the residue.

[0034] In the embodiments of this utility model, please refer to Figure 6 The auxiliary mechanism 3 includes a sleeve 31, which is rotatably connected to the arc surface of the feed pipe 6. An adjusting pipe 32 is fixedly connected to one side of the sleeve 31. A positioning hole 33 is opened on the arc surface of the sleeve 31, and a rotating rod 34 is threaded through the inner wall of the positioning hole 33. When the liquid to be processed is connected to the feed pipe 6 through the conveying pipe, the angle of the feed pipe 6 needs to be adjusted according to the auxiliary mechanism 3, so as to improve the stability of the connection between the conveying pipe and the feed pipe 6 and avoid affecting the connection effect between the two pipes due to excessive deviation of the connection angle. Several auxiliary grooves 36 are opened on the arc surface of the rotating rod 34. The auxiliary grooves 36 are evenly distributed on the rotating rod 34. The auxiliary grooves 36 can increase the friction of the rotating rod 34 surface and increase the speed of rotating the rotating rod 34. Several marking blocks 35 are provided on the arc surface of the sleeve 31. The marking blocks 35 are fixedly connected to one side of the centrifuge body 1. The marking blocks 35 can facilitate the worker to adjust the angle of the adjusting rod and improve the adjustment accuracy.

[0035] The working principle of the anti-clogging horizontal screw centrifuge discharge port provided by this utility model is as follows: When it is necessary to clean and guide the residue accumulated on the discharge port body 7, the motor 202 installed on the fixing block 201 is started. The movement of the motor 202 will drive the power rod 203 to rotate through the output end. The movement of the power rod 203 will drive the two cleaning plates 204 and the adjusting block 206 to move along one side of the discharge port body 7. The movement of the cleaning plates 204 can clean and scrape off the residue remaining on one side of the discharge port body 7. The movement of the adjusting block 206 will drive the abutment rod 2... 07 pushes the accumulated impurities on the other side of the slag discharge port body 7, causing the bottom of the accumulated residue to loosen. The movement of the abutment rod 207 will drive the steel rope 208 to move. The movement of the steel rope 208 will drive the rotating shaft 210 to rotate inside the support rod 209. The rotating shaft 210 will drive the coil spring 213 to compress. At this time, the rotating shaft 210 can drive the adjusting cylinder 211 and the stirring blade 212 to rotate. At this time, the accumulated residue can be stirred, so that the accumulated residue can be discharged from the slag discharge port body 7, avoiding blockage of the slag discharge port body 7.

[0036] When the angle of the feed tube 6 needs to be adjusted, rotate the rotating rod 34 in the positioning hole 33. The rotating rod 34 will move away from the feed tube 6. At this time, the contact effect between the arc end of the rotating rod 34 and the feed tube 6 can be released. Then, rotate the angle of the adjusting tube 32 on the feed tube 6 to rotate the adjusting tube 32 to the appropriate position. Then, rotate the rotating rod 34 in the positioning hole 33 again. The rotating rod 34 will then come into contact with the feed tube 6, and the angle of the adjusting tube 32 will be fixed again.

[0037] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
