[0004] When dust is prevented from being emitted from slag, water is sprayed onto the slag. However, in actual use, this method of dust prevention by spraying water onto slag is prone to waste of resources.

[0005] The overload alarm function of ordinary ash removal machines used in thermal power plant furnaces is not good, which affects the performance of the ash removal machines used in thermal power plant furnaces.

[0006] The crushing of slag is not convenient enough. Therefore, this utility model provides a slag discharge machine for thermal power plant furnaces with an alarm function to solve the above-mentioned problems. Summary of the Invention

[0007] The purpose of this utility model is to provide a slag discharge machine for thermal power plant furnaces with an alarm function, in order to solve the problems mentioned in the background art, which are that dust prevention is achieved by spraying water on the slag, which easily leads to resource waste in actual use, and that the overload alarm effect of ordinary slag discharge machines for thermal power plant furnaces is not good, thus affecting the use effect of the slag discharge machine for thermal power plant furnaces, and that the crushing of slag is not convenient enough.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a slag discharge machine for a thermal power plant furnace with an alarm function, comprising a support frame, wherein a slag aggregate is fixedly installed on the middle side of its upper end, and a discharge pipe is fixedly provided at the lower end of the slag aggregate;

[0009] Also includes:

[0010] A connecting plate is movably installed inside the lower side of the support frame, and a loading and unloading plate is fixedly installed on the upper inner side of the connecting plate. A connecting block is movably connected to the upper outer side of the loading and unloading plate, and a dust cover is fixedly installed on the upper end of the connecting block. The upper side of the dust cover is fixedly connected to the outer side of the feeding pipe. A storage battery is fixedly installed inside the middle side of the loading and unloading plate, and a power strip is connected to the left side of the storage battery via a cable. An alarm is fixedly installed on the left side of the loading and unloading plate, and a damper is fixedly installed on the lower inner side of the loading and unloading plate. A moving plate is fixedly installed on the upper side of the damper, and a spring is fixedly installed on the lower outer side of the moving plate. A plug is fixedly installed on the lower left side of the moving plate.

[0011] The inlet is located on the upper left side of the slag aggregate, and a cylinder is fixedly installed inside the left side of the slag aggregate. A baffle plate is fixedly installed on the upper side of the cylinder. A motor is fixedly installed on the upper middle side of the slag aggregate, and a slag structure is fixedly installed on the lower side of the motor.

[0012] Preferably, the slag crushing structure includes a connecting rod, which is fixedly installed at the lower end of the motor, and a vertical rod is movably connected to the outer side of the upper end of the connecting rod. Crushing blades are fixedly connected to the outer side of the lower end of both the vertical rod and the outer side of the lower end of the connecting rod.

[0013] Preferably, the connecting rod and the vertical rod are connected by an interlocking mechanism, and the vertical rods are distributed at equal angles about the center point of the connecting rod.

[0014] Preferably, the vertical rod is connected to the slag mass by rotation, and the upper vertical cross-section of the vertical rod has a "T" shape.

[0015] Preferably, the connecting block and the loading / unloading plate are connected by a snap-fit ​​mechanism, and the connecting blocks are symmetrically distributed about the center line of the dust cover.

[0016] Preferably, the movable plate and the loading / unloading plate are connected in a sliding manner.

[0017] Preferably, the plug is connected to the movable plate via a retractable cable harness.

[0018] Preferably, the baffle plate is slidably connected to the inlet, and the cross-sectional shape of the baffle plate is arc-shaped.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the slag discharge machine for thermal power plant furnaces with alarm function is convenient for crushing slag, convenient for overload alarm, and convenient for dust prevention of slag during crushing.

[0020] By pouring the slag into the crushed material through the inlet, the cylinder is activated, causing the cylinder to slide the baffle plate upward inside the inlet, so that the upper side of the baffle plate contacts the upper side of the inlet, which facilitates dust prevention of the slag during crushing. Then, the loading and unloading plate is installed inside the support frame, causing the loading and unloading plate to slide backward inside the support frame, so that the loading and unloading plate slides under the connecting block, and then the loading and unloading plate fits into the dust cover. The connecting plate then drives the loading and unloading plate to slide to the appropriate position inside the support frame, so that the dust cover and connecting block cover the loading and unloading plate, which facilitates dust prevention of the slag during material discharge.

[0021] By starting the motor, the motor drives the connecting rod to rotate inside the slag aggregate, which in turn causes the vertical rod, which is meshed with the connecting rod, to rotate inside the slag aggregate. This causes both the connecting rod and the vertical rod to drive the crushing blade to rotate in opposite directions, allowing the crushing blade to crush the slag inside the slag aggregate, thus facilitating the crushing of the slag.

[0022] The crushed material from the internal slag mass is fed through the feed pipe into the loading and unloading plate. The material causes the moving plate to slide downwards inside the loading and unloading plate, which in turn compresses the damper, which in turn compresses the spring. This causes the plug to slide downwards, allowing it to connect to the power strip. The battery then supplies power to the plug, which transmits the power through a retractable wiring harness to the alarm for overload detection. This allows the operator to close the valve on the feed pipe. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0032] Please see Figure 1-7This utility model provides a technical solution: a slag discharge machine for a thermal power plant furnace with an alarm function, comprising: a slag collection 4 fixedly installed on the upper middle side of a support frame 1, and a discharge pipe 9 fixedly installed at the lower end of the slag collection 4; a connecting plate 2 movably installed inside the lower side of the support frame 1, and a loading / unloading plate 3 fixedly installed on the upper inner side of the connecting plate 2; a connecting block 11 movably connected to the upper outer side of the loading / unloading plate 3; and a dust cover 10 fixedly installed on the upper end of the connecting block 11, wherein the upper side of the dust cover 10 is connected to the discharge pipe 9. The loading and unloading plate 3 is fixedly connected to the outside. A battery 12 is fixedly installed inside the middle of the loading and unloading plate 3, and a power strip 13 is connected to the left side of the battery 12 via a cable. An alarm 18 is fixedly installed on the left side of the loading and unloading plate 3, and a damper 14 is fixedly installed on the lower side of the loading and unloading plate 3. A movable plate 16 is fixedly installed on the upper side of the damper 14, and a spring 15 is fixedly installed on the lower outer side of the movable plate 16. A plug 17 is fixedly installed on the lower left side of the movable plate 16. The loading and unloading plate 3 is then installed inside the support frame 1. The loading and unloading plate 3 causes the connecting plate 2 to slide backward inside the support frame 1, thereby causing the loading and unloading plate 3 to slide under the connecting block 11. This allows the loading and unloading plate 3 to fit against the dust cover 10, and the connecting plate 2 causes the loading and unloading plate 3 to slide to a suitable position inside the support frame 1. This allows the dust cover 10 and the connecting block 11 to cover the loading and unloading plate 3, facilitating dust prevention for the material residue during feeding. The crushed material residue inside the crushed material collection 4 falls into the loading and unloading plate 3 through the feeding pipe 9, causing the material residue to move. The plate 16 slides downward inside the loading and unloading plate 3, thereby causing the moving plate 16 to drive the damper 14 to compress, which in turn causes the moving plate 16 to drive the spring 15 to compress, causing the moving plate 16 to drive the plug 17 to slide downward, thereby causing the plug 17 to be plugged into the socket plate 13, thereby causing the battery 12 to provide power to the plug 17, and causing the plug 17 to transmit power to the alarm 18 through the retractable wire harness for alarm, facilitating overload alarm, thereby causing the operator to close the valve on the feed pipe 9;

[0033] The inlet 5 is located on the upper left side of the slag collection 4. A cylinder 19 is fixedly installed inside the left side of the slag collection 4, and a baffle plate 20 is fixedly installed on the upper side of the cylinder 19. A motor 21 is fixedly installed on the upper middle side of the slag collection 4, and a slag structure is fixedly installed on the lower side of the motor 21. The slag is poured into the slag collection 4 through the inlet 5. The cylinder 19 is started, causing the cylinder 19 to drive the baffle plate 20 to slide upward inside the inlet 5, so that the upper side of the baffle plate 20 contacts the upper side of the inlet 5, which facilitates dust prevention of the slag during crushing. The motor 21 is started, causing the motor 21 to drive the slag structure to crush the slag inside the slag collection 4, which facilitates the crushing of the slag.

[0034] When using a boiler ash removal machine with alarm function in a thermal power plant, specifically as follows: Figure 1 , Figure 4 and Figure 6 In the process, the slag is poured into the crushed material collection 4 through the inlet 5. The baffle plate 20 is slidably connected to the inlet 5, and the cross-sectional shape of the baffle plate 20 is arc-shaped. The cylinder 19 is activated, causing the cylinder 19 to drive the baffle plate 20 to slide upward inside the inlet 5, so that the upper side of the baffle plate 20 contacts the upper side of the inlet 5, which facilitates dust prevention of the slag during crushing. The connecting block 11 is connected to the loading and unloading plate 3 by a snap-fit ​​mechanism, and the connecting block 11 is closed. The loading and unloading plates 3 are symmetrically distributed on the left and right sides of the center line of the dust cover 10. Then, the loading and unloading plates 3 are installed inside the support frame 1, so that the loading and unloading plates 3 drive the connecting plates 2 to slide backward on the lower side inside the support frame 1. This allows the loading and unloading plates 3 to slide on the lower side of the connecting blocks 11, thereby making the loading and unloading plates 3 fit against the dust cover 10. The connecting plates 2 drive the loading and unloading plates 3 to slide to a suitable position inside the support frame 1, so that the dust cover 10 and the connecting blocks 11 cover the loading and unloading plates 3, which facilitates dust prevention of material residue during material unloading.

[0035] Specific examples Figure 1 , Figure 3 , Figure 5 and Figure 7 In the process, the motor 21 is started, and the connecting rod 6 and the vertical rod 7 are connected by meshing. The vertical rod 7 is distributed at equal angles about the center point of the connecting rod 6, so that the motor 21 drives the connecting rod 6 to rotate inside the middle side of the slag collection 4. This causes the vertical rod 7, which is meshed with the connecting rod 6, to rotate inside the upper side of the slag collection 4. The vertical rod 7 and the slag collection 4 are connected by rotation, and the upper vertical cross-section of the vertical rod 7 is a "T" shape. This causes the connecting rod 6 and the vertical rod 7 to drive the crushing blade 8 to rotate in opposite directions, so that the crushing blade 8 crushes the slag inside the slag collection 4, which facilitates the crushing of the slag.

[0036] Specific examples Figure 1 and Figure 2 In the process, the crushed material inside the slag collection 4 is dropped into the loading and unloading plate 3 through the feed pipe 9. The moving plate 16 is connected to the loading and unloading plate 3 by sliding, so that the material drives the moving plate 16 to slide downward inside the loading and unloading plate 3. This causes the moving plate 16 to drive the damper 14 to compress, which in turn causes the moving plate 16 to drive the spring 15 to compress. The plug 17 is connected to the moving plate 16 through a retractable wire harness, so that the moving plate 16 drives the plug 17 to slide downward, so that the plug 17 is plugged into the socket plate 13. This allows the battery 12 to provide power to the plug 17, and the plug 17 transmits the power to the alarm 18 through the retractable wire harness for overload alarm, so that the operator can close the valve on the feed pipe 9.
