[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the utility model.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

For ordinary technicians in this field, the specific meaning and scope of the above terms in the present invention can be understood according to the specific situation.

[0032] The existing desulfurized gypsum material distribution device has only one discharge port. When the conveyor below the discharge port fails or the discharge port is blocked, the production needs to be stopped. The desulfurized gypsum material distribution device for power generation of the present application is provided with two forked discharge ports and cooperates with the driving mechanism 2, the crank arm 4 and the material distribution baffle 3 to achieve two-way selection of gypsum discharge, and prevent sudden failures from affecting normal production.

[0033] See also Figure 1-Figure 2 As shown, a desulfurized gypsum distributing device for power production comprises:

[0034] A hopper 1, wherein a first fork 11 and a second fork 12 are provided at the lower end of the hopper 1, a first slide pipe 13 is provided on the first fork 11, a second slide pipe 14 is provided on the second fork 12, and a connecting piece is provided at the connection between the first fork 11 and the second fork 12;

[0035] A crank arm 4, the bottom end of which is movably connected to the connecting member;

[0036] A driving mechanism 2, wherein the fixed end of the driving mechanism 2 is fixed to the device body, and the driving end of the driving mechanism 2 is connected to one side of the upper end of the crank arm 4;

[0037] The material dividing baffle 3 is installed on the other side of the crank arm 4, and the size of the material dividing baffle 3 matches the size of the first fork 11 and the second fork 12; it is used to form a good blocking effect on one of the spare forks to prevent gypsum from accidentally falling into the spare fork.

[0038] The material receiving mechanism is a belt conveyor 6, and the belt conveyor 6 is installed below the first chute 13 and the second chute 14 respectively.

[0039] In this embodiment, when the swing of the crank arm 4 is controlled by the output end of the driving mechanism 2 in the hopper 1, the position of the material dividing baffle 3 at the first fork 11 or the second fork 12 is controlled, so that the gypsum falling material is transported on which belt conveyor 6, a spare channel for transporting gypsum is provided.

[0040] It realizes the two-way selection of gypsum blanking and flexibly carries out gypsum dehydration production.

[0041] In this embodiment, the other fork of the double fork at the lower end of the hopper 1 is used for backup to prevent the production from stopping due to the failure of the conveyor below one of the forks or the blockage of the discharge port during the actual production process. At this time, the swing of the crank arm 4 is controlled by the output end of the driving mechanism 2, and then the position of the material dividing baffle 3 at the other fork is controlled, so that the belt conveyor 6 at the end where the gypsum material is not broken can be transported, realizing the flexible choice of gypsum material, and making the gypsum dehydration production. Of course, in other embodiments, multiple forks can also be designed at the lower end of the hopper 1 for backup, but considering the cost investment and actual practicality, a double fork is used for design in this embodiment.

[0042] It should be noted that, in the present embodiment, the upper port of the double fork and the hopper 1 can be connected by means of snap-fitting or screw fixing, and the first chute 13 and the first fork 11 / the second chute 14 and the second fork 12 can be connected by means of snap-fitting or screw fixing. However, when selecting a specific connection method, it can be selected according to the actual production situation. The present device is mainly used for gypsum blanking. Considering the heavy product, it is more reliable to select bolt fixing. This connection method is more firm and improves the stability of the production process.

[0043] Specifically, in another embodiment, the material receiving mechanism is also the belt conveyor 6 installed below the first chute 13 and the material stacking bin 7 installed below the second chute 14 .

[0044] In this embodiment, the belt conveyor 6 under another spare fork is replaced with a stacking bin 7. The purpose is to consider that the cost of installing a spare belt conveyor 6 is too high, and the use of the stacking bin 7 can save costs. When the belt conveyor 6 is fixed, the swing of the crank arm 4 is controlled by the output end of the driving mechanism 2, and then the position of the material dividing baffle 3 at the second fork 12 is controlled, so that the gypsum falls into the stacking bin 7, and the heavy gypsum in the stacking bin 7 is transported by other more cost-saving methods, so that the gypsum dehydration production can be carried out flexibly. Of course, when starting the stacking bin 7, the belt conveyor 6 can be repaired in time. After the belt conveyor 6 is repaired, the first fork 11 is started again to drop the material. This solution not only solves the problem that the equipment fails and cannot be produced when there is only one drop port, but also reduces the corresponding equipment cost.

[0045] Specifically, in a specific embodiment, the driving mechanism 2 is an electric push rod, the fixed end of the electric push rod is fixed to the device body, and the driving end of the electric push rod is connected to one side of the upper end of the crank arm 4.

[0046] The control mode of the electric push rod in this embodiment adopts electric control. The electric push rod is a new type of linear actuator composed of a motor push rod and a control device, which can only realize simple push-pull actions. The maximum thrust can basically meet the on-site production of this device. Through on-site design and installation of a control box, its open and closed positions are designed with manual locking devices to prevent misoperation. When the belt conveyor 6 fails and cannot be put into use, the driving end of the electric push rod can drive the crank arm 4, thereby driving the material distribution baffle 3 to adjust the open and closed positions, and directly guide the gypsum to the belt conveyor 6 or the stacking bin 7 through the slide pipe, meeting the on-site use requirements.

[0047] Specifically, in another specific embodiment, the driving mechanism 2 is a push-pull cylinder, the fixed end of the push-pull cylinder is fixed to the device body, and the driving end of the push-pull cylinder is connected to one side of the upper end of the crank arm 4.

[0048] In this embodiment, the push-pull cylinder is an electric cylinder, which is a modular product that integrates the servo motor and the lead screw, converting the rotary motion of the servo motor into linear motion, and at the same time converting the best advantages of the servo motor - precise speed control, precise revolution control, and precise torque control - into precise speed control, precise position control, and precise thrust control; realizing a series of products with high-precision linear motion. The thrust of the electric cylinder is greater than that of the electric push rod, and the stroke is also longer. In actual production, when the fork is large and the production volume is large, the push-pull cylinder of the electric cylinder can be selected, otherwise the electric push rod can be selected.

[0049] Specifically, in a specific embodiment, the desulfurized gypsum material distribution device for power generation further includes a silo wall rapper 5, which is installed on the outside of the hopper 1. The vibration of the silo wall rapper 5 can prevent the inner wall of the hopper 1 from sticking, ensure the smooth falling of the gypsum material, and keep the inner wall of the hopper 1 clean.

[0050] In this embodiment, the silo wall vibrator 5 can be an electromagnetic vibrator, which can be used in various vibration machines, such as feeders, small conveyors, vibrating screens, vibration platforms and silo wall vibrations, etc. It is flexible and convenient to use, and the vibration intensity can be adjusted at will by a controller. The pulsating voltage obtained by half-wave rectification of the electromagnetic vibrator alternating current is added to the coil, and the device that uses its electromagnetic force to vibrate the movable iron core is called an electromagnetic vibrator. The movable iron core is supported by a spring of rubber, fiberglass, steel, etc., so that the entire vibration system resonates. The electromagnetic vibrator can be installed on the side wall of the hopper or the unloading chute to prevent the material from arching or adhering to the side wall, and can also be used in places where the material is evenly loaded into the container by vibration.

[0051] In some specific embodiments, the electromagnetic vibrator can be a hammer-type electromagnetic vibrator, which includes an armature and a hammer head connected together. After the excitation coil is energized, the armature is attracted to the iron core, and the hammer head hits the warehouse wall. After the power is off, the hammer head is reset by gravity. The circuit is automatically controlled by a delay relay, vibrating 20 times per minute, the electromagnetic suction force is 35 to 45 kg, and the use effect is good. In other embodiments, the electromagnetic vibrator can also be a spring-type electromagnetic vibrator. The iron core of the spring-type electromagnetic vibrator with a coil is connected to the base of the vibrator, and the iron core is inserted into the armature. The position of the armature is determined by the spring and the nut. The hammer head that hits the warehouse wall is fixed together with the armature, and the base of the vibrator is directly fixed on the warehouse wall. When selecting the stiffness of the spring, the natural frequency of the armature should be close to the frequency of the alternating current. After power is turned on, the electromagnetic vibrator vibrates at a frequency of 3000Hz, and the use effect is good. In some other embodiments, the electromagnetic vibrator can also be a resonant electromagnetic vibrator, which is composed of a vibrating body, a resonant spring, an electromagnet, an armature, and a base. The electromagnet and the armature are fixed to the vibrating body and the base respectively. The mass m1 of the vibrating body and the electromagnet and the mass m2 of the base and the armature form an elastic system through elastic elements. Since the base is fastened to the silo wall, a single-point directional forced vibration is formed. The specific selection can be made according to actual production, and no specific limitation is made again.

[0052] Specifically, in a specific embodiment, a movable hinge is provided at the connection between the first fork 11 and the second fork 12; the bottom end of the crank arm 4 is connected to one end of the movable hinge. One end of the movable hinge is installed at the connection between the first fork 11 and the second fork 12, and the other end of the movable hinge is connected to the bottom end of the crank arm 4. In a specific implementation, the movable hinge can easily rotate the crank arm 4 from one end of the fork to the other end of the fork, thereby driving the material dividing baffle 3 to block or dredge the fork.

[0053] Specifically, see Figure 3 In a specific embodiment, the first fork 11 is a vertical structure, and the second fork 12 and the first fork 11 form a connecting structure with a downward tilt angle.

[0054] In this embodiment, the two forks are designed to use a vertical structure for the first fork 11 (the main fork), and the second fork 12 (the backup fork) is connected to the first fork 11 at a downward angle. The advantage of this solution is that the first fork 11, as the main fork, adopts a vertical structure for material dropping. This vertical structure allows rapid material dropping and increases production efficiency. The backup second fork 12 is at a downward angle to the first fork 11, which can prevent gypsum from falling into the second fork 12 during normal production.

[0055] Specifically, see Figure 4 In another specific embodiment, the first fork 11 and the second fork 12 both form a connecting structure with a downward tilt angle.

[0056] In this embodiment, the two forks are designed to be designed with a downward inclined angle. This design purpose is adopted in consideration of the high failure frequency of the belt conveyor. When the failure rate of the belt conveyor is high, a structure in which the first fork 11 and the second fork 12 divide the angle equally is adopted. The spare fork and the main fork can produce the same production efficiency. This ensures that when one of the belt conveyors 6 fails, good production connection can be achieved without delaying production.

[0057] Specifically, in a specific embodiment, the hopper 1, the first chute 13, the second chute 14 and the material distribution baffle 3 are made of stainless steel. Considering that the production process uses materials such as gypsum, stainless steel is used to make the hopper 1, the chute and the material distribution baffle 3, which can achieve strong corrosion resistance, high reliability and long service life of the device.
