Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of stirring equipment, in particular to a slurry preparation device for desulfurization. BACKGROUND

[0002] The limestone slurry preparation stirring and mixing device plays a key role in the industrial flue gas desulfurization process. When it operates, the limestone raw material is first transported into the device according to the established requirements, and an appropriate amount of water needs to be added. Then, the stirrer is used for full and efficient stirring and mixing, so as to prepare the limestone slurry that meets the standard, and realize the effective removal of sulfides in the flue gas.

[0003] In the use process, it is very important to control the slurry capacity and control the feeding amount. If the feeding amount is not properly controlled, the slurry is easy to overflow the stirrer due to excessive amount. Once this situation occurs, the limestone raw material will leak to the surrounding environment, causing material waste and pollution to the surrounding environment. In the conventional technology, the monitoring of the adding capacity in the stirrer is often simply realized by relying on manual observation. The operating personnel rely on their own experience and direct observation of the naked eye to judge the adding capacity of the limestone raw material, water and other materials in the stirrer. It is difficult to accurately judge the specific value of the capacity, and it is easy to have a large error. It is impossible to confirm whether the raw material reaches the accurate adding amount required by the process, resulting in that the concentration of the limestone slurry does not meet the standard of the subsequent desulfurization process.

DETAILED DESCRIPTION

[0029] The embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below by referring to the accompanying drawings are exemplary, and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0030] As Figures 1-11 shown, the slurry preparation device for desulfurization according to the embodiment of the present application includes a stirring assembly 100, an adjusting assembly and a control box 103.

[0031] Specifically, the stirring assembly 100 comprises a stirring box 101, a conveying pipe 102 arranged on the top of the stirring box 101 and communicated with the stirring box 101, and a stirring piece arranged in the stirring box 101, the adjusting assembly comprises a screw rod 201b, a driving piece, an adapter piece, a floating ball 201c and a transmission piece, one side of the outer circumferential wall of the stirring box 101 is provided with an adjusting box communicated with the stirring box 101, the floating ball 201c is arranged in the adjusting box and connected with the adapter piece through the transmission piece, the screw rod 201b is arranged in the conveying pipe 102 along the length direction of the conveying pipe 102, the adapter piece is movably connected between the driving piece and the screw rod 201b, the driving piece is used for driving the adapter piece to rotate, when the water level rises, the floating ball 201c drives the adapter piece to move towards the direction away from the screw rod 201b through the transmission piece, and when the water level in the adjusting box rises to a target water level line, the displacement of the floating ball 201c can drive the adapter piece to move to a separated position, and the adapter piece in the separated position is separated from the screw rod 201b.

[0032] It can be understood that, since the adjusting box is communicated with the stirring box 101, the water level line in the stirring box 101 is always in the adjusting box, and as the water level line rises, the floating ball 201c rises and drives the adapter piece to move through the transmission piece, before specific application, the water level line corresponding to the accurate value of the raw material addition amount can be confirmed first, and the water level line is set as the target water level line, then in actual application, the raw material is first added to the conveying pipe 102, then the driving piece drives the screw rod 201b to rotate to realize the feeding to the stirring box 101, as the raw material in the stirring box 101 is continuously added, the water level line in the stirring box 101 continuously rises, the floating ball 201c synchronously rises and drives the adapter piece to move, until the water level line rises to the target water level line, the displacement of the floating ball 201c drives the adapter piece to move a stroke that is just enough to completely separate the adapter piece from the screw rod 201b, then the driving relationship between the driving piece and the screw rod 201b no longer exists, the screw rod 201b stops rotating and further stops discharging.

[0033] Similarly, as the stirring box 101 discharges outward, the water level line descends, the sinking of the floating ball 201c triggers reverse feedback, the adapter piece moves back to reset and is connected with the screw rod 201b again, the driving piece and the screw rod 201b reestablish the connection relationship, and the screw rod 201b can restart to rotate to continue discharging.

[0034] Further, the stirring box 101 is further provided with a control box 103 on the outside, and the control box 103 is used for controlling the overall operation of the equipment.

[0035] The slurry preparation device for desulfurization of the embodiment of the application, the adjusting box is arranged on one side of the stirring box 101, the floating ball 201c is arranged in the adjusting box, the floating ball 201c is connected with the adapter through the transmission member, the adapter is connected between the screw rod 201b and the driving member, the adapter is movable to realize separation and connection with the screw rod 201b, when the water level in the adjusting box rises to the target water level line, the displacement amount of the floating ball 201c can drive the adapter to move to the separation position, the adapter in the separation position is separated from the screw rod 201b, thereby, by establishing the connection structure between the floating ball 201c and the adapter, the movement of the floating ball 201c can be used to drive the adapter to disconnect the connection between the screw rod 201b and the driving member when the raw material addition amount is in place, and then automatic stopping of feeding is realized, the problems of material overflow and waste and substandard slurry concentration caused by excessive addition are avoided, and compared with manual observation, the application can automatically judge the feeding state by using the floating ball 201c combined with the change of the water level line when feeding, and the power input of the screw rod 201b is automatically disconnected when the feeding is in place, the intelligent control of the feeding process is realized, and then precise feeding is realized.

[0036] In some embodiments, as shown in Figure 7 The transmission member includes a hinged plate 201d, a connecting rod, a pushing member and a support rod 202f, the support rod 202f is horizontally arranged and one end thereof is connected to the side wall of the adjusting box facing the stirring box 101, the top of the hinged plate 201d is movably connected to the other end of the support rod 202f, the bottom thereof is connected to one end of the connecting rod, the connecting rod is horizontally arranged and the other end thereof is connected to the floating ball 201c, one end of the pushing member is connected to the hinged plate 201d and the other end thereof is connected to the adapter, the upward movement of the floating ball 201c can drive the hinged plate 201d to rotate upward around the support rod 202f, and the upward rotation of the hinged plate 201d can drive the pushing member to drive the adapter to separate from the screw rod 201b. Thus, when the water level line rises, the floating ball 201c can drive the connecting rod to move, and then the movement of the connecting rod can drive the hinged plate 201d to rotate, the rotation of the hinged plate 201d can drive the pushing member to move, the movement of the pushing member can drive the adapter to rotate, and then the separation of the adapter and the screw rod 201b is realized to stop feeding.

[0037] In some embodiments, as shown in Figure 7As shown, the transmission member further comprises a rotating rod 201e and a driving turntable 205, and the pushing member comprises a pressing column 204e, a guide rod 204d and a pushing rod, the rotating rod 201e is arranged on the hinged plate 201d and is perpendicular to the extension direction of the connecting rod, one end of the rotating rod 201e is rotationally connected with the inner wall of the adjusting box, the other end of the rotating rod 201e penetrates through the side plate of the adjusting box which is away from the stirring box 101 and is connected with the driving turntable 205, and a first elastic member is arranged on the rotating rod 201e between the rotating rod 201e and the inner wall of the adjusting box, both ends of the first elastic member are connected with the adjusting box and the rotating rod 201e respectively, the pressing column 204e is vertically arranged, the bottom of the pressing column 204e is in contact with the driving turntable 205, the top of the pressing column 204e is movably connected with the horizontally arranged guide rod 204d, the other end of the guide rod 204d extends towards the side wall of the adjusting box which is close to the stirring box 101 and is movably connected with the pushing rod, the pushing rod is connected with the adapter, the outer periphery of the driving turntable 205 is provided with a protruding pushing part, and the connecting rod extends towards the direction close to the stirring box 101.

[0038] Specifically, when the floating ball 201c drives the hinged plate 201d to rotate, the rotating rod 201e rotates with the hinged plate 201d and drives the first elastic member to store energy, and the driving turntable 205 at the other end of the rotating rod 201e rotates, with the rotation of the driving turntable 205, the pushing part is in contact with the pressing column 204e and limits the pressing column 204e to be lifted upwards, the movement of the pressing column 204e can drive the guide rod 204d to move, the movement of the guide rod 204d can force the pushing rod to move, and the movement of the pushing rod can pull the adapter to move to realize the separation from the spiral rod 201b.

[0039] In addition, when the water level drops, the rebound of the first elastic member can drive the hinged plate 201d to reset to prepare for the next driving.

[0040] In some embodiments, a fixed plate 204f is movably connected to the outside of the pressing column 204e, a pressing disc 204g is fixed to one end of the pressing column 204e, the bottom of the pressing disc 204g is provided with a rotating disc, the bottom of the fixed plate 204f is fixed with a fourth elastic member 204i, and one end of the fourth elastic member 204i is fixed to the top of the pressing disc 204g. Thus, when the driving turntable 205 rotates, the pushing part presses the pressing disc 204g, at this time, the pressing column 204e can be driven to move, at the same time, the fourth elastic member 204i can be pressed, then the guide rod 204d can be driven to move through the movement of the pressing column 204e, the fixed plate 204f is used for supporting the pressing column 204e to prevent the pressing column 204e from deviating, when the driving turntable 205 reverses and the pushing part above is separated from the pressing disc 204g, at this time, the pressing column 204e can be driven to return to the original position through the rebound of the fourth elastic member 204i, and finally the pushing member can return to the original position.

[0041] In some embodiments, as shown in FIG. 6, the pushing member further comprises a fixed plate 204f movably connected to the outside of the pressing column 204e, a pressing disc 204g fixed to one end of the pressing column 204e, the bottom of the pressing disc 204g is provided with a rotating disc, the bottom of the fixed plate 204f is fixed with a fourth elastic member 204i, and one end of the fourth elastic member 204i is fixed to the top of the pressing disc 204g. Figure 9And Figure 10 As shown, the driving disc includes an inner disc 205a, an outer disc 205b, and a limiting disc 204h. The outer disc 205b is sleeved on the outer periphery of the inner disc 205a. The inner disc 205a is provided with a limiting plate on one side of the outer disc 205b. The limiting plate is provided with a plurality of adjusting holes arranged at intervals in the circumferential direction. The outer disc 205b is provided with fixing holes corresponding to the adjusting holes. The outer disc 205b is provided with an adjusting piece. The adjusting piece includes a limiting block protruding outward in the radial direction of the outer disc 205b and an assembly piece matched with the adjusting hole and the fixing hole. The limiting disc 204h is sleeved on the outer side of the outer disc 205b. The limiting disc 204h has a stop block protruding inward. Thus, by adjusting the position of the adjusting piece, the interval between the limiting block and the stop block can be adjusted. Therefore, the control of the driving disc 205 can be realized according to different water levels. The screw rod 201b can be stopped at different water levels. The application has high flexibility and wide range of application.

[0042] Specifically, by separating the assembly piece from the adjusting hole, the connection between the inner disc 205a and the outer disc 205b can be released. Then, the outer disc 205b is rotated. By rotating the outer disc 205b to a specified position and then reassembling the adjusting piece with the adjusting hole to realize connection, the distance between the stop block and the limiting block has changed. When the water level changes again and the floating ball 201c drives the inner disc 205a to rotate, the stop block and the limiting block will contact again, thereby driving the outer disc 205b to rotate. Since the interval between the stop block and the limiting block has changed, the water level line when the driving stops will also change. Thus, the screw rod can be stopped at different water levels.

[0043] In some embodiments, as shown in Figure 11 The limiting clamping plate 205c is fixed on one side of the pull bar 205d. The pull bar 205d is sleeved with a connecting disc 205e on the outer side. The connecting disc 205e is fixed on one side with a third elastic piece 205f. The pull bar 205d is movably connected with a positioning sleeve 205g on the outer side. The positioning sleeve 205g is sleeved on the outer side of the third elastic piece 205f. The outer side of the positioning sleeve 205g is provided with a support plate. The pull bar 205d can be supported by the positioning sleeve 205g. By pulling the pull bar 205d, the limiting clamping plate 205c can be moved away from the adjusting hole. At the same time, the connecting disc 205e can be moved. By moving the connecting disc 205e, the third elastic piece 205f can be subjected to a squeezing force. At this time, the limiting of the outer disc 205b can be released. After the outer disc 205b is rotated to a specified position, the pull bar 205d is released. By the rebound of the third elastic piece 205f, the limiting clamping plate 205c can be returned to the original position and matched with the adjusting hole again. Then, the outer disc 205b and the inner disc 205a can be connected again.

[0044] In some embodiments, as shown in Figure 6 And Figure 7As shown, the push rod comprises a vertical rod, a transverse rod 204b and a longitudinal rod 204a, all of which are located on the outer surface of the adjusting box, the vertical rod is vertically arranged and has a driving plate 204c at the bottom, the driving plate 204c is provided with a sliding groove movably connected with a guide rod 204d, the transverse rod 204b is vertically connected at the top of the longitudinal rod 204a and is arranged in parallel with the rotating rod 201e, the other end of the transverse rod 204b is connected with the longitudinal rod 204a, and the other end of the longitudinal rod 204a is connected with the adapter and arranged in parallel with the supporting rod 202f. Thus, the movement of the guide rod 204d will extrude the sliding groove to move the driving plate 204c, the movement of the driving plate 204c can drive the vertical rod to move, the vertical rod drives the longitudinal rod 204a to move through the transverse rod 204b, and finally the adapter is moved to separate from the spiral rod 201b through the longitudinal rod 204a, so as to realize automatic stopping of material.

[0045] In some embodiments, as shown in Figures 3-5 As shown, one end of the spiral rod 201b towards the adjusting box is provided with a driving cover 203a, the inner circumferential surface of the driving cover 203a is provided with a plurality of spaced-apart clamping teeth, including an adapter rod 203c and a second elastic member 203g, one end of the adapter rod 203c is fitted in the driving cover 203a and located outside the spiral rod 201b, and the end of the adapter rod 203c is provided with a tapered block 203b matched with the clamping teeth, the adjusting box is provided with a supporting seat 203f, the adapter rod 203c is movably arranged in the supporting seat 203f, the second elastic member 203g is connected between the adapter rod 203c and the supporting seat 203f and is sleeved on the adapter rod 203c, and the longitudinal rod 204a is connected with the adapter rod 203c.

[0046] Thus, the floating ball 201c floats to move the adapter rod 203c towards the direction away from the spiral rod 201b through the hinged plate 201d, the rotating rod 201e, the driving disc 205 and the push rod, and with the outward movement of the adapter rod 203c, the tapered block 203b is out of the clamping teeth, when the tapered block 203b is completely separated from the clamping teeth, the adapter rod 203c is separated from the driving cover 203a, that is, the adapter rod 203c is disconnected with the spiral rod 201b, and the process will compress the second elastic member 203g, when the water level line drops, the second elastic member 203g will be pushed back again, and the tapered block 203b will be reset and re-engaged with the clamping teeth, so as to realize the connection between the adapter rod 203c and the spiral rod 201b, and the subsequent driving member can drive the spiral rod 201b to rotate and feed.

[0047] In some embodiments, as shown in Figure 3 and Figure 4As shown, the longitudinal rod 204a is provided with a vertical pushing plate 203 at one end of the stirring box 101, the top of the pushing rod is provided with a transition rod 203h extending horizontally towards the driving cover 203a, the transition rod 203h is below the adapter rod 203c, the outer periphery of the adapter rod 203c is connected with a movable frame 203e, and the bottom of the movable frame 203e is connected with the transition rod 203h.
