[0058] Ginseng Figures 1 to 5A specific embodiment of a granular solid conveying device disclosed. The granular solid conveying device includes: a box body 400, having a storage space, and the storage space is used to hold granular solids. The conveying mechanism 100 includes a driving device 130 and a screw conveying assembly, and the screw conveying assembly has an inlet end 170 and an outlet end, the inlet end 170 is located in the storage space, and the outlet end is located outside the box body 400, and the driving device 130 drives the screw conveying assembly to rotate, and conveys the granular solid from the inlet end 170 to the outlet end, so as to convey the granular solid from the inside of the box body 400 to the outside of the box body 400. The rotating part 500 is connected to the screw conveying assembly, and is used to drive the screw conveying assembly along the direction of the axis of the screw conveying assembly (that is, Figure 2 Move in the direction of the dotted line b).

[0059] Here, the granular solid is described by taking activated carbon as an example.

[0060] In traditional activated carbon replacement methods, a discharge port is provided at the bottom or lower side of the tank. The activated carbon is discharged from this port. However, due to the poor fluidity of activated carbon, it is prone to clogging at the discharge port, making it difficult to discharge. In this case, the activated carbon must be manually discharged from the discharge port, which not only increases the labor intensity and generates a lot of dust, but also because the activated carbon contains saturated harmful waste gases, they can be easily inhaled by on-site personnel, causing harm to the workers.

[0061] However, the granular solid conveying device disclosed in this embodiment, by providing a conveying mechanism 100 and a rotating part 500, when the driving device 130 drives the spiral conveying assembly and the rotating part 500 to rotate, the rotating part 500 enters the interior of the box body 400 along the direction of the axis of the spiral conveying assembly. At the same time, the driving device 130 drives the spiral conveying assembly to rotate, and the activated carbon is transported from the inside of the box body 400 to the outside of the box body 400 to achieve the replacement of the activated carbon. This replacement method not only saves a lot of manpower, but also reduces dust. At the same time, it can also avoid direct contact between workers and activated carbon, thereby preventing the dust generated by the activated carbon that is saturated with harmful exhaust gas adsorption from being inhaled into the body by on-site personnel, avoiding harm to the workers' bodies.

[0062] The box body 400 is provided with an outlet portion (not shown), and the outlet end is provided on the side of the box body 400, along the longitudinal direction (ie, Figure 1 By arranging the outlet portion in the box body 400, it is convenient to clean the residual activated carbon in the box body 400.

[0063] Illustratively, the screw conveying assembly includes: a drive device 130 having a drive end; an auger 160 connected to the drive end; and a hose 140 sleeved with the auger 160. The hose 140 has an inlet end 170 and an outlet end, wherein the inlet end 170 is located inside the housing 400 and the outlet end is located outside the housing 400. The drive device 130 drives the auger 160 to rotate, conveying granular solids in the housing 400 from the inlet end 170 to the outlet end, thereby conveying the granular solids from the housing 400 to the outside of the housing 400.

[0064] Specifically, refer to Figure 1 and Figure 2 As shown, the driving device 130 can be a servo motor or other equipment. The spiral auger 160 includes a rotating shaft 150 and a spiral blade (not shown in the figure). The hose 140 is sleeved on the periphery of the spiral blade. The hose 140 and the rotating shaft 150 can be rotatably connected through a bearing. When the driving device 130 drives the rotating shaft 150 to rotate through the driving end, the hose 140 does not rotate with the rotating shaft 150. The hose 140 has an inlet end 170 and an outlet end. The inlet end 170 is located in the accommodating space. The outlet end is located outside the box 400. When the driving device 130 drives the spiral auger 160 to rotate, the granular solid in the box 400 is transported from the inlet end 170 to the outlet end, so as to transport the activated carbon solid from the inside of the box 400 to the outside of the box 400, thereby enabling the replacement of the activated carbon.

[0065] Furthermore, a mounting frame 410 is installed on the surface of the box body 400 for installing the conveying mechanism 100. In order to facilitate inspection and maintenance of the conveying mechanism 100, a climbing frame 420 is installed on one side of the box body 400.

[0066] Exemplarily, the granular solid conveying device further includes: a limiting mechanism 200, connected to the screw conveying assembly, for driving the screw conveying assembly along its axial direction (ie, Figure 2 The inlet end 170 is moved in the longitudinal direction (ie, the direction of the arrow b in the middle) to limit the movement of the inlet end 170 in the box body 400. Figure 1 The depth is in the direction of arrow a).

[0067] Specifically, refer to Figures 2 to 5As shown, the limiting mechanism 200 includes: a fixed portion 220, which is connected to the rotating shaft 150. A movable portion 230, which is sleeved with the rotating shaft 150 and connected to the rotating portion 500. The fixed portion 220 is engaged with the movable portion 230, and the fixed portion 220 and the movable portion 230 are arranged opposite to each other along the axis of the rotating shaft 150, and an accommodating cavity is provided between the fixed portion 220 and the movable portion 230. A spring 240 is arranged in the accommodating cavity. The elastic force direction of the spring 240 is along the direction of the axis of the rotating shaft 150. A braking portion is connected to the movable portion 230 and is movably connected to the movable portion 230.

[0068] Among them, both the fixed part 220 and the movable part 230 can be cylindrical structures, rectangular structures, or other irregular three-dimensional structures. The opposite ends of the fixed part 220 and the movable part 230 are both open, and there is a accommodating cavity between the fixed part 220 and the movable part 230, that is, the fixed part 220 has a first accommodating cavity, and the movable part 230 is provided with a second accommodating cavity. The first accommodating cavity and the second accommodating cavity are arranged opposite to each other for accommodating the spring 240. The spring 240 is sleeved on the rotating shaft 150. One end of the spring 240 is arranged in the first accommodating cavity. The other end of the spring 240 is arranged in the second accommodating cavity. The fixed part 220 is also provided with a first clamping block 270. The movable part 230 is also provided with a second clamping block 280. The first clamping block 270 and the second clamping block 280 are engaged with each other to achieve a fixed connection between the fixed part 220 and the movable part 230. The first clamping block 270 and the second clamping block 280 are separated, thereby achieving separation of the fixed portion 220 and the movable portion 230 .

[0069] The fixed portion 220 is fixedly connected to the rotating shaft 150. The fixed portion 220 and the rotating shaft 150 can be fixedly connected by welding. The movable portion 230 is sleeved with the rotating shaft 150, and when the fixed portion 220 and the movable portion 230 are in a separated state, that is, Figure 4 The movable portion 230 does not rotate with the rotating shaft 150. When the fixed portion 220 and the movable portion 230 are fixedly connected, the rotating shaft 150 drives the fixed portion 220 to rotate while also driving the movable portion 230 to rotate. At this time, the fixed portion 220 and the movable portion 230 are in a closed state, that is, as shown in FIG. Figure 3 The movable portion 230 is fixedly connected to the rotating portion 500, for example, the movable portion 230 and the rotating portion 500 are fixedly connected by welding. When the movable portion 230 rotates with the fixed portion 220, the rotating portion 500 rotates together with the movable portion 230.

[0070] The braking element is a clutch ring 250. A slot 260 is provided on the sidewall of the movable portion 230. One end of the clutch ring 250 is inserted into the slot 260 and slidably connected therewith. Pulling the clutch ring 250 compresses the spring 240, causing the first engaging block 270 to engage with the second engaging block 280, thereby securing the fixed portion 220 to the movable portion 230. Releasing the clutch ring 250 separates the fixed portion 220 from the movable portion 230.

[0071] Furthermore, in order to facilitate pulling the clutch pull ring 250, a brake line 210 is fixedly provided at the other end of the clutch pull ring 250. The brake line 210 extends from the clutch pull ring 250 to the outside of the box body 400. Figure 1 It can be seen that the brake line 210 can be manually pulled to pull the clutch pull ring 250, so that the fixed part 220 and the movable part 230 can be fixedly connected, thereby achieving synchronous rotation of the fixed part 220 and the movable part 230, and then the conveying mechanism 100 can drive the rotating part 500 to rotate and rotate toward the bottom of the box body 400.

[0072] Exemplarily, the rotating portion 500 is a spiral drill bit, and the diameter of the spiral drill bit gradually increases along the direction of its central axis.

[0073] Specifically, refer to Figure 3 and Figure 4 As shown, the structure of the rotating part 500 is as follows Figure 3 or as Figure 4 The auger head shown. The diameter of the auger head increases gradually as it approaches the movable portion 230 along its central axis. By providing the rotating portion 500, when the driving device 130 rotates the auger 160, the brake line 210 is pulled, securing the fixed portion 220 to the movable portion 230, thereby driving the rotating portion 500 to rotate toward the bottom of the housing 400.

[0074] Furthermore, to prevent the auger from crushing the activated carbon, a protective portion 510 is installed at the end of the auger. The protective portion 510 can be spherical, hemispherical, or other shapes, as long as the surface of the protective portion 510 in contact with the activated carbon is an arc structure.

[0075] Exemplarily, the granular solid conveying mechanism 100 further includes: a conveying pipe 110 connected to the outlet end (marked in the figure) and a collecting box 180 located below the outlet of the conveying pipe 110 for collecting the activated carbon conveyed outside the box body 400 .

[0076] Illustratively, the granular solid conveying device further includes: a control panel 120 , wherein the control panel 120 is electrically connected to the driving device 130 and is used to control the start, pause, and shut down of the driving device 130 .

[0077] Specifically, refer to Figure 1 As shown, in order to realize automatic control of the granular solid conveying device and further save manpower, the granular solid conveying device is further provided with a control panel 120. The control panel 120 realizes automatic control of the driving device 130.

[0078] Furthermore, to further save manpower, the control panel 120 can be placed on the ground, and the driving device 130 can be controlled to start, pause, and stop by manually stepping on it. It should be noted that the control method of the control panel 120 and the driving device 130 is a prior art. Those skilled in the art are already familiar with the specific principles, and will not be described in detail here.

[0079] For example, the control part 300 has a gripping end 310 and a connecting end 320, wherein the connecting end 320 is connected to the rotating part 500 and is used to adjust the gripping end 310 and the vertical direction (ie, the longitudinal direction) Figure 1 The included angle between the rotating part 500 and the vertical direction (i.e. the longitudinal direction) is adjusted. Figure 1 The angle between the two axes is the direction of the arrow a).

[0080] Specifically, refer to Figure 1 As shown, the control unit 300 can be a rod-shaped structure, a plate-shaped structure, or the like. In this embodiment, the control unit 300 is preferably a rod-shaped structure. The connecting end 320 of the control unit 300 is fixedly connected to the rotating unit 500. The manual hand grasps the gripping end 310 to adjust the angle between the control unit 300 and the vertical direction, thereby driving the rotating unit 500 to move and adjust the angle between the rotating unit 500 and the vertical direction. This allows the position of the inlet end 170 to be adjusted, facilitating the transport of activated carbon from the inside of the box 400 to the outside of the box 400.

[0081] In this embodiment, the control panel 120 is used to first activate the drive device 130, which drives the auger 160 to rotate, transporting the activated carbon from the inlet port 170 to the outlet port, where it is collected in the collection tank 180 through the delivery pipe 110. The auger 160, i.e., the rotating shaft 150, rotates. The brake line 210 can be manually pulled, thereby pulling the clutch ring 250. The spring 240 is compressed, and the first and second clamping blocks 270 and 280 engage, securing the fixed portion 220 and the movable portion 230. The movable portion 230 then drives the rotating portion 500 to rotate, which in turn drives the auger 160 toward the bottom of the housing 400. If the brake line 210 is released, the spring force causes the first and second clamping blocks 270 and 280 to separate, separating the fixed portion 220 and the movable portion 230. At this point, the rotating portion 500 stops rotating, and the auger 160 also stops screwing into the bottom of the box 400. Therefore, by providing the limiting mechanism 200, the depth of the auger 160 in the longitudinal direction inside the box 400 can be controlled, thereby enabling activated carbon at different depths inside the box 400 to be transported from inside the box 400 to outside the box 400. Through the above-described method, the activated carbon can be replaced, which not only saves a lot of manpower but also reduces dust. At the same time, it can also prevent workers from coming into direct contact with the activated carbon, thereby preventing the dust generated by activated carbon that has been saturated with harmful exhaust gases from being inhaled by on-site personnel, thereby preventing harm to the workers' bodies.

[0082] Another specific embodiment of a granular solid conveying device. The granular solid conveying device includes: a box body 400 having a storage space, wherein the storage space is used to hold granular solids. The conveying mechanism 100 includes a driving device 130 and a screw conveying assembly, wherein the screw conveying assembly has an inlet end 170 and an outlet end, wherein the outlet end is located in the storage space, and the inlet end 170 is located outside the box body 400. The driving device 130 drives the screw conveying assembly to rotate, and conveys the granular solid from the inlet end 170 to the outlet end, so as to convey the granular solid from the outside of the box body 400 to the inside of the box body 400. The rotating part 500 is connected to the screw conveying assembly, and is used to drive the screw conveying assembly along the direction of the axis of the screw conveying assembly (i.e., Figure 2 Move in the direction of the dotted line b).

[0083] The granular solid conveying device provided in this embodiment is not only used to convey activated carbon from inside the box body 400 to outside the box body 400 to achieve the replacement of activated carbon. The granular solid conveying device is also used to convey activated carbon from outside the box body 400 to inside the box body 400 to achieve the filling of activated carbon. When filling activated carbon, the outlet end of the spiral conveying assembly is set in the accommodating space of the box body 400. The inlet end 170 of the spiral conveying assembly is set outside the box body 400, and the activated carbon covers the inlet end 170. First, the driving device 130 is turned on through the control panel 120, and the driving device 130 drives the spiral auger 160 to rotate, which can convey the activated carbon from the inlet end 170 to the outlet end, thereby being able to convey the activated carbon into the box body 400 to achieve the filling of activated carbon. This method of filling activated carbon not only saves a lot of manpower, but also reduces dust. At the same time, it can also avoid direct contact between workers and activated carbon, thereby preventing the dust generated by the activated carbon that is saturated with harmful waste gas from being inhaled into the body by on-site personnel, avoiding harm to the workers' bodies.
