Description

Technical Field

[0001] This utility model relates to the field of sand and gravel cleaning technology, and in particular to a sand and gravel cleaning equipment for cement plants. Background Technology

[0002] A cement plant is an enterprise specializing in cement production. Its core function is to process natural raw materials such as limestone, clay, and iron ore into cement through a series of physical and chemical processes. Cement is widely used as a basic cementitious material in fields such as civil engineering, water conservancy projects, and national defense construction. Sand and gravel in cement plants are indispensable raw materials and aggregates in the cement production process. They are mainly used to prepare cement clinker and concrete mixing. Their quality directly affects the strength, durability, and safety of cement products and construction projects. Vibrating stone washing machines are one of the core equipment for cleaning sand and gravel in cement plants. They are mainly used to remove clay, dust, and impurities from the surface of sand and gravel to ensure that the cleanliness of sand and gravel meets the requirements of concrete production.

[0003] Existing cement plant sand and gravel washing equipment still has some problems. Traditional vibrating screens rely solely on vibration for screening, and clay and fine sand easily adhere to the surface of the screen holes, leading to reduced screening efficiency or even blockage. Utility Model Content

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a cement plant sand and gravel washing equipment. Through the auxiliary structure, the screen is repeatedly pulled upward and the material is turned upward, which breaks the adhesion layer between the clay and the screen, so that the clay is separated from the screen with the water flow and the screen is prevented from clogging.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cement plant sand and gravel washing equipment, including a first support, a discharge hopper fixedly connected to the upper end face of the first support, a second support provided at the front end of the first support, shock-absorbing structures fixedly connected to the four opposite corners of the upper end face of the second support, a frame fixedly connected to the upper end face of the four shock-absorbing structures, a connecting frame fixedly connected to the upper end of the frame, a sliding groove provided at the lower part of the two inner side walls of the connecting frame, a screen provided inside the two sliding grooves, an extension frame fixedly connected to the upper part of the rear end face of the second support, and an auxiliary structure fixedly connected to the upper end of the extension frame; The auxiliary structure includes a base plate, a base fixedly connected to the rear side of one of the upper surfaces of the base plate, a servo motor fixedly connected to the upper surface of the base, a reducer fixedly connected to the output end of the servo motor, a disc fixedly connected to the output end of the reducer, a connecting shaft fixedly connected to the edge of the disc away from the reducer, a drive shaft rotatably connected to the end of the connecting shaft, a telescopic rod rotatably connected to the end of the drive shaft, a storage box fixedly connected to the front end of the telescopic rod, and the storage box fixedly connected to the rear side of the upper surface of the screen. Through the above technical solution, by starting the servo motor, the servo motor drives the reducer to start, the reducer drives the disc to rotate, the disc drives the connecting shaft to rotate around the center of the disc, thereby driving one end of the drive shaft to rotate along the axis of the center of the disc. During this process, the telescopic rod will be pulled to move back and forth along the sleeve. At this time, the storage box drives the screen to slide up and down along the two slide grooves, driving multiple L-shaped ribs to move up and down, turning over the sand and gravel on the screen, reducing the blockage caused by mud and sand adhering to the screen holes.

[0006] Furthermore, a bearing housing is fitted on the output end of the reducer, and the bearing housing is fixedly connected to the base. A sleeve is fitted on the outside of the telescopic rod, and the sleeve is fixedly connected to the upper surface of the base plate. The above technical solution facilitates the improvement of the stability of the disk rotation through the bearing housing, and also limits the movement trajectory of the telescopic rod through the sleeve.

[0007] A water inlet valve is fixedly connected to the center of the upper end face of the storage tank, and a water outlet valve is fixedly connected to the lower front end of one side wall of the storage tank. Damping fluid is installed inside the storage tank. The above technical solution involves opening the inlet valve before use to add damping fluid into the storage tank, and then discharging the damping fluid that absorbed the heat generated by the vibration through the outlet valve to cool it down after use.

[0008] A water collection trough is fixedly connected to the lower end of the frame, and a drain pipe is fixedly connected to the lower end of one side wall of the water collection trough near the front. With the above technical solution, the mud and water fall into the water collection tank and are discharged through the low-end drainage pipe.

[0009] A kinetic energy recovery structure is fixedly connected to the center of the front end face of the second bracket. The kinetic energy recovery structure includes a mounting plate. Three support bars are horizontally arranged and fixedly connected to the center of the lower end face of the mounting plate. The other ends of the three support bars are fixedly connected to the front end face of the second bracket. A third bracket is fixedly connected to one side of the lower end face of the mounting plate. A first bearing is fixedly connected to one side wall of the third bracket. A first mounting bracket is fixedly connected to the inner ring of the first bearing. A connecting rod is slidably connected inside the first mounting bracket. A waterwheel plate is fixedly sleeved at the end of the connecting rod away from the mounting plate. A shaft is fixedly connected to the end of the connecting rod away from the waterwheel plate. A limit plate is fixedly connected to the end of the shaft. A short gear is fixedly sleeved at the center of the outer wall of the shaft. A long gear that meshes with the short gear is provided at the lower end of the short gear. A generator is fixedly connected to one end of the long gear. Water and sediment impact the blades on the waterwheel, causing the waterwheel to rotate. The waterwheel then rotates the inner rings of the two second bearings and the first bearing, which in turn rotates the shaft. The shaft then rotates the short gear, which in turn rotates the long gear. Finally, the long gear rotates the generator. The generated electricity is rectified and regulated by a rectifier and voltage regulator before being sent to the battery for storage.

[0010] A fourth bracket is fixedly connected to the center of the lower end face of the mounting plate. A fifth bracket is fixedly connected to the lower end face of the mounting plate at the end of the fourth bracket away from the third bracket. A short gear is located between the fourth and fifth brackets. A long gear is rotatably connected between the fourth and fifth brackets at the lower part. A retaining ring is fitted on the outer side of the shaft on the side of the waterwheel between the fourth and fifth brackets. A limiting bolt is provided at the center of the front end face of the retaining ring. The rear end of the limiting bolt passes through the front end face of the retaining ring and its end is attached to the front end face of the shaft. Through the above technical solution, by pushing the shaft, the shaft pushes the connecting rod and the waterwheel disc to move to one side, so that multiple blades on the waterwheel disc are in the position where the water flows down, driving the short gear and the retaining ring to move to one side. After reaching the position, the retaining ring is moved to one side of the third bracket, and the limiting bolt is rotated so that the end of the limiting bolt is attached to the outer surface of the shaft for fixation, preventing the shaft from sliding laterally due to the impact of the water flow.

[0011] A dust cover is fixedly connected to the front of the lower end face of the mounting plate. A second bearing is fixedly connected to the upper center of both sides of the dust cover. A second mounting bracket is fixedly connected to the inner ring of each of the two second bearings. The two second mounting brackets are respectively sleeved on the outside of the connecting rod. The above technical solution prevents external dust from affecting the transmission between the short gear and the long gear.

[0012] Multiple water spray pipes are arranged front and back at the top of the connecting frame. The multiple water spray pipes are connected to a water tank through a water pump. A vibrating motor is fixedly connected at the center of one side wall of the frame. Multiple L-shaped ribs are fixedly connected front and back at the top of the screen.

[0013] The above technical solution uses a water pump to deliver water from the water tank to multiple spray pipes, which then spray water through nozzles at the lower end of the pipes. This is a common technical solution in existing sand washing machine spray systems and will not be elaborated on here. By starting the vibrating motor, the vibration is transmitted to the screen inside the connecting frame, which vibrates and screens the mud and sand on the gravel. The multiple L-shaped ribs provide more friction as they move up and down, turning the gravel over.

[0014] This invention has the following advantages: by starting the servo motor, the servo motor drives the reducer to start, the reducer drives the disc to rotate, the disc drives the connecting shaft to rotate around the center of the disc, thereby driving one end of the drive shaft to rotate along the center of the disc as the axis. During this process, the telescopic rod will be pulled to move back and forth along the sleeve. At this time, the storage box drives the screen to slide up and down along the two slide grooves, driving multiple L-shaped ribs to move up and down, turning over the sand and gravel on the screen, reducing the blockage caused by mud and sand adhering to the screen holes.

[0015] The water flow and sediment impact the blades on the waterwheel, causing the waterwheel to rotate. The waterwheel then rotates the inner rings of the two second bearings and the first bearing, which in turn rotates the shaft. The shaft then rotates the short gear, which in turn rotates the long gear. Finally, the long gear rotates the generator. The generated electricity is rectified and regulated by a rectifier and voltage regulator before being sent to the battery for storage. Attached Figure Description

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.

[0023] Reference Figure 1-5 This utility model provides an embodiment of a cement plant sand and gravel washing equipment, including a first support 1. A discharge hopper 2 is fixedly connected to the upper end of the first support 1. A second support 3 is provided at the front end of the first support 1. Shock-absorbing structures 4 are fixedly connected to the four opposite corners of the upper end of the second support 3.

An extension frame 11 is fixedly connected to the upper part of the rear end of the second support 3. An auxiliary structure 10 is fixedly connected to the upper end of the extension frame 11.

[0024] like Figure 1 , 2 As shown in Figure 4, the auxiliary structure 10 includes a base plate 1001. A base 1002 is fixedly connected to the rear side of one side of the upper surface of the base plate 1001. A servo motor 1003 is fixedly connected to the upper surface of the base 1002. A reducer 1004 is fixedly connected to the output end of the servo motor 1003. A disc 1006 is fixedly connected to the output end of the reducer 1004. A connecting shaft 1007 is fixedly connected to the edge of the end face of the disc 1006 away from the reducer 1004. A drive shaft 1008 is rotatably connected to the end of the connecting shaft 1007. A telescopic rod 1009 is rotatably connected to the end of the drive shaft 1008. A storage box 1011 is fixedly connected to the front end of the telescopic rod 1009. The storage box 1011 is fixedly connected to the screen. At the rear of the upper surface of the screen 16, the servo motor 1003 is started, which drives the reducer 1004 to start. The reducer 1004 drives the disc 1006 to rotate, and the disc 1006 drives the connecting shaft 1007 to rotate around the center of the disc 1006. This drives one end of the drive shaft 1008 to rotate along the axis of the center of the disc 1006. During this process, the telescopic rod 1009 is pulled to move back and forth along the sleeve 1010. At this time, the storage box 1011 drives the screen 16 to slide up and down along the two sliding grooves 15, which drives the multiple L-shaped ribs 14 to move up and down, turning over the sand and gravel on the screen 16 and reducing the blockage caused by mud and sand adhering to the screen holes of the screen 16.

[0025] A bearing seat 1005 is fitted on the output end of the reducer 1004. The bearing seat 1005 is fixedly connected to the base 1002. A sleeve 1010 is fitted on the outside of the telescopic rod 1009. The sleeve 1010 is fixedly connected to the upper surface of the base plate 1001. This facilitates the improvement of the rotation stability of the disc 1006 through the bearing seat 1005, and also limits the movement trajectory of the telescopic rod 1009 through the sleeve 1010.

[0026] A water inlet valve 1012 is fixedly connected to the center of the upper end face of the storage tank 1011, and a water outlet valve 1013 is fixedly connected to the lower front end of one side wall of the storage tank 1011. The storage tank 1011 is filled with damping fluid. The vibration of the screen 16 is achieved by opening the water inlet valve 1012 before use to add damping fluid into the storage tank 1011. After use, the damping fluid that absorbs the heat generated by the vibration is discharged through the water outlet valve 1013 to cool down.

[0027] A water collection trough 5 is fixedly connected to the lower end of the frame 7. A drain pipe 6 is fixedly connected to the lower end of one side wall of the water collection trough 5. Mud and water fall into the water collection trough 5 and are discharged through the drain pipe 6 at the lower end.

[0028] like Figure 1 and 3 As shown, a kinetic energy recovery structure 9 is fixedly connected to the center of the front end face of the second bracket 3. The kinetic energy recovery structure 9 includes a mounting plate 901. Three support bars 902 are horizontally arranged and fixedly connected to the center of the lower end face of the mounting plate 901. The other ends of the three support bars 902 are all fixedly connected to the front end face of the second bracket 3. A third bracket 903 is fixedly connected to one side of the lower end face of the mounting plate 901. A first bearing 904 is fixedly connected to one side wall of the third bracket 903. A first mounting bracket 905 is fixedly connected to the inner ring of the first bearing 904. A connecting rod 906 is slidably connected inside the first mounting bracket 905. A waterwheel disc 907 is fixedly sleeved at the end of the connecting rod 906 away from the mounting plate 901. A shaft is fixedly connected to the end of the connecting rod 906 away from the waterwheel disc 907. A limiting plate 910 is fixedly connected to the end of shaft 909. A short gear 912 is fixedly sleeved at the center of the outer wall of shaft 909. A long gear 913 meshes with the short gear 912 at the lower end. A generator 914 is fixedly connected to one end of the long gear 913. Water flow and mud impact the blades on the waterwheel disc 907, causing the waterwheel disc 907 to rotate. The waterwheel disc 907 drives the inner rings of the two second bearings 917 and the first bearing 904 to rotate, thereby driving shaft 909 to rotate. Shaft 909 drives short gear 912 to rotate, short gear 912 drives long gear 913 to rotate, and finally long gear 913 drives generator 914 to rotate. The generated electrical energy is rectified and regulated by a rectifier and voltage regulator before being sent to the battery for storage.

[0029] A fourth bracket 908 is fixedly connected to the lower end face of the mounting plate 901 near the center. A fifth bracket 911 is fixedly connected to the lower end face of the mounting plate 901 at the end of the fourth bracket 908 away from the third bracket 903. A short gear 912 is located between the fourth bracket 908 and the fifth bracket 911. A long gear 913 is rotatably connected between the fourth bracket 908 and the fifth bracket 911 at the lower part. A retaining ring 919 is fitted on the outer side of the shaft 909 on the side of the waterwheel disc 907 between the fourth bracket 908 and the fifth bracket 911. A limiting bolt 915 is provided at the center of the front end face of the retaining ring 919. The rear end of 915 passes through the front end face of the retaining ring 919, and its end is attached to the front end face of the shaft 909. By pushing the shaft 909, the shaft 909 pushes the connecting rod 906 and the waterwheel 907 to move to one side, so that multiple blades on the waterwheel 907 are in the position where the water flows down, driving the short gear 912 and the retaining ring 919 to move to one side. After reaching the position, the retaining ring 919 is moved to one side of the third bracket 903. The limiting bolt 915 is rotated so that the end of the limiting bolt 915 is attached to the outer surface of the shaft 909 for fixation, preventing the shaft 909 from sliding laterally due to the impact of the water flow.

[0030] A dustproof shell 916 is fixedly connected to the front of the lower end face of the mounting plate 901. A second bearing 917 is fixedly connected to the upper center of both sides of the dustproof shell 916. A second mounting bracket 918 is fixedly connected to the inner ring of each of the two second bearings 917. The two second mounting brackets 918 are respectively sleeved on the outside of the connecting rod 906 to prevent external dust from affecting the transmission between the short gear 912 and the long gear 913.

[0031] Multiple water spray pipes 8 are arranged front to back on the upper end of the connecting frame 13. The multiple water spray pipes 8 are connected to a water tank through a water pump. A vibration motor 12 is fixedly connected to the center of one side wall of the frame 7. Multiple L-shaped ribs 14 are fixedly connected front to back on the upper end of the screen 16. Water in the water tank is transported to the multiple water spray pipes 8 through the water pump. The water is sprayed and cleaned through the nozzles at the lower end of the multiple water spray pipes 8. This is a common technical solution in the existing sand washing machine water spraying system, which will not be described in detail here. By starting the vibration motor 12, the vibration is transmitted to the screen 16 inside the connecting frame 13. The vibration is used to vibrate and screen the mud and sand on the sand and gravel. The multiple L-shaped ribs 14 provide more friction when they move up and down, turning the sand and gravel.

[0032] Working principle: During use, unwashed sand and gravel are added into the discharge hopper 2. After the flip-up door at the bottom of the discharge hopper 2 is opened, the sand and gravel fall onto the screen 16 by their own weight. This is the existing sand and gravel feeding technology, which will not be elaborated on here. Then, the vibration motor 12 is started. The centrifugal force generated by the high-speed rotation of the adjustable eccentric blocks at both ends of the rotor shaft converts the rotational motion of the motor into directional reciprocating vibration, thereby providing continuous power for the vibrating machinery. This is a commonly used technical solution in the vibration motor 12, which will not be elaborated on here. The vibration is transmitted to the screen 16 inside the connecting frame 13. The vibration screens the mud and sand on the sand and gravel. The generated vibration is buffered by four damping structures 4, which are mainly composed of elastic elements and damping elements. The two work together to absorb and dissipate the vibration energy. This is a commonly used technical means in the existing sand and gravel machine vibration damping system, which will not be elaborated on here.

[0033] The water in the tank is then pumped to multiple spray pipes 8, and sprayed through nozzles at the lower end of the spray pipes 8 for cleaning. This is a common technical solution in the existing sand washing machine spray system, and will not be elaborated on here. During the cleaning process, the servo motor 1003 is started, which drives the reducer 1004 to start. The reducer 1004 drives the disc 1006 to rotate, and the disc 1006 drives the connecting shaft 1007 to rotate around the center of the disc 1006. This drives one end of the drive shaft 1008 to rotate along the axis of the center of the disc 1006. During this process, the telescopic rod 1009 is pulled to move back and forth along the sleeve 1010. At this time, the storage box 1011 drives the screen 16 to slide up and down along the two sliding grooves 15, which drives multiple L-shaped ribs 14 to move up and down, turning over the sand and gravel on the screen 16 and reducing the blockage caused by mud and sand adhering to the screen holes of the screen 16.

[0034] The vibration of the screen 16 is mitigated by adding damping fluid to the storage tank 1011 before use by opening the inlet valve 1012. The damping fluid is essentially a high-viscosity fluid, and its vibration absorption is based on the viscosity of the liquid. When liquid molecules move relative to each other due to vibration, the internal friction between molecules will hinder this movement, converting the kinetic energy of the vibration into internal energy, thereby attenuating the vibration. This is a common technical solution for damping fluid to absorb vibration, which will not be elaborated on here. After use, the damping fluid that has generated heat from absorbing vibration is discharged through the outlet valve 1013 to cool it down. Alternatively, an external delivery pump can be connected to the storage tank to circulate the damping fluid, or the damping fluid can be continuously delivered and discharged to prevent overheating. This is an auxiliary vibration reduction structure. There are no restrictions on the technical solution for replacing the damping fluid, and it can be adjusted according to the actual usage.

[0035] Sediment and water fall into the water collection tank 5 and are discharged through the lower drain pipe 6. At this time, by pushing the shaft 909, the shaft 909 pushes the connecting rod 906 and the waterwheel 907 to move to one side, so that the multiple blades on the waterwheel 907 are in the position where the water falls. This drives the short gear 912 and the retaining ring 919 to move to one side. After reaching the position, the retaining ring 919 is moved to one side of the third bracket 903. The limiting bolt 915 is rotated so that the end of the limiting bolt 915 is attached to the outer surface of the shaft 909 for fixation, preventing the shaft 909 from sliding laterally due to the impact of the water flow. Due to the setting of the long gear 913, the short gear 912 remains engaged during the lateral movement. The water flow and sediment impact the blades on the waterwheel 907, causing the waterwheel 907 to rotate. The waterwheel 907 drives the inner rings of the two second bearings 917 and the first bearing 904 to rotate, which in turn drives the shaft 909 to rotate. The shaft 909 drives the short gear 912 to rotate, the short gear 912 drives the long gear 913 to rotate, and finally the long gear 913 drives the generator 914 to rotate. When the rotor rotates, the magnetic field it generates moves relative to the conductors in the stator. At this time, the magnetic flux through the stator coil changes periodically with the rotor rotation, which satisfies the conditions of the law of electromagnetic induction. According to Faraday's law of electromagnetic induction, an induced electromotive force is generated in the stator coil. If the coil is closed, an induced current is formed. The generated electrical energy is rectified and regulated by a rectifier and voltage regulator before being sent to the battery for storage. This is a commonly used technical solution in existing power generation systems, and will not be elaborated on further here.

[0036] The equipment also includes an integrated controller. The integrated controller receives signals from various components through input ports. These signals are processed and used as the basis for control decisions. The integrated controller then uses a control algorithm to process the input signals and generates control outputs according to predetermined rules. Based on the results of the control algorithm, the integrated controller sends signals to the actuators through the output ports. The integrated controller can also coordinate the work of various components, such as adjusting the working order and timing of multiple devices to ensure the efficient operation of the system. Furthermore, the integrated controller continuously monitors the operating status of each component and adjusts the control strategy in a timely manner based on feedback to cope with possible changes or anomalies. This solution is a commonly used technical method in the prior art and will not be elaborated on further here.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
