[0006] It can be seen from the above technical scheme that the utility model arranges a guide hopper at the outlet of the discharge channel of the weighing device to collect the dialysis powder discharged from the discharge channel, so as to avoid the dialysis powder from spilling out of the container at the outlet of the discharge channel due to excessive speed when being discharged downward along the inclined discharge channel, thereby preventing waste and the actual amount of dialysis powder being less than the weighing value due to the spilling of dialysis powder, thereby affecting the accuracy of treatment; and the vertically arranged discharge pipe can quickly discharge all the dialysis powder in the guide hopper into the container below the container, thereby avoiding the loss of dialysis powder, ensuring that the actual amount of dialysis powder contained in the container is consistent with the weighing value, and realizing accurate quantification of dialysis powder.

[0007] As described above, the dialysis powder weighing device, optionally, the discharge end of the discharge channel extends out of the frame, and the guide hopper is rotatably arranged on the frame and can rotate between a first position and a second position; when the guide hopper is located at the first position, the guide hopper is located below the outlet of the discharge channel, and when the guide hopper is located at the second position, the guide hopper is away from below the outlet of the discharge channel and is located inside the frame.

[0008] Furthermore, the guide hopper has a connecting portion, which is provided with a through hole for the rotating shaft to pass through. The connecting portion is connected to the guide hopper mounting beam on the frame through the rotating shaft and can rotate around the rotating shaft. The guide hopper is located below the guide hopper mounting beam.

[0009] The guide hopper is connected to the frame through a rotating shaft, so that the guide hopper can rotate relative to the frame. When in use, the guide hopper is rotated outside the frame.

[0027] like Figure 1As shown, the dialysis powder weighing device of this embodiment includes a frame 1, a powder bin 2, a flow meter 3, a feeding channel 4, a feeding control valve 5, a discharge channel 6, a guide hopper 7 and a discharge pipe 8. The powder bin 2 of this embodiment is arranged on the top of the frame 1, and the powder bin 2 is used to hold dialysis powder. A discharge port (not shown) is arranged at the bottom of the powder bin 2, and the flow meter 3 is arranged at the discharge port of the powder bin 2, and the inlet of the flow meter 3 is connected to the discharge port of the powder bin 2.

[0028] The feeding channel 4 is connected to the outlet of the flow meter 3. The dialysis powder in the powder bin 2 is discharged from the outlet at the bottom of the powder bin 2, and is quantitatively measured by the flow meter 3, and then enters the feeding channel 4 from the outlet of the flow meter 3. The feeding control valve 5 is arranged at the outlet of the feeding channel 4. When the dialysis powder entering the feeding channel 4 through the flow meter 3 reaches the required weighing value, the feeding channel 4 can be closed by the feeding control valve 5 to stop the dialysis powder from continuing to discharge. The feeding control valve 5 of this embodiment is specifically a plate gate valve.

[0029] The discharge channel 6 is connected to the outlet of the discharge control valve 5. The discharge channel 6 extends obliquely downward from the discharge end of the discharge control valve 5. The discharge end of the discharge channel 6 extends out of the frame 1 to facilitate the storage of the dialysis powder after weighing. The guide hopper 7 is located below the outlet of the discharge channel 6. The guide hopper 7 is used to collect the dialysis powder discharged from the discharge channel 6. The bucket-shaped structure of the guide hopper 7 can concentrate the dialysis powder and prevent the dialysis powder from spilling. The discharge pipe 8 is connected to the guide hopper 7. The discharge pipe 8 is arranged at the bottom outlet of the guide hopper 7, and the discharge pipe 8 and the guide hopper 7 are fixed. The discharge pipe 8 is a hollow pipe extending vertically. After the guide hopper 7 collects the dialysis powder discharged from the discharge channel 6, the dialysis powder is discharged vertically downward into the container (not shown) through the discharge pipe 8.

[0030] The utility model provides a guide hopper 7 and a discharge pipe 8, so that the dialysis powder obliquely discharged from the discharge channel 6 can be redirected and discharged vertically. The discharged dialysis powder vertically falls into a corresponding container below the discharge pipe 8. The guide hopper 7 has a buffering effect on the collection of the dialysis powder, which solves the problem that the dialysis powder directly discharged from the inclined discharge channel is easily spilled out of the container due to excessive speed. The discharge pipe 8 pointing vertically downward can quickly discharge all the dialysis powder downward into the container, so that accurate quantitative measurement of the dialysis powder can be achieved.

[0031] Optionally, the guide hopper 7 of this embodiment is rotatably disposed on the frame 1 , and the guide hopper 7 can be rotated to a first position located below the outlet of the discharge channel 6 , or rotated to a second position located inside the frame 1 away from below the outlet of the discharge channel 6 .

[0032] Reference Figure 2 , Figure 3 and Figure 4The guide hopper 7 of this embodiment is rotatably connected to a crossbeam of the frame 1 through a rotating shaft 9, and the crossbeam is a guide hopper mounting beam 1-1 for mounting the guide hopper 7. The guide hopper 7 has a connecting portion 7-1, and a through hole 7-1a is provided on the connecting portion 7-1 for the rotating shaft 9 to pass through. The connecting portion 7-1 is connected to the guide hopper mounting beam 1-1 through the rotating shaft 9. The connecting portion 7-1 (guide hopper 7) is located below the guide hopper mounting beam 1-1, so that the guide hopper 7 will not be affected when rotating around the rotating shaft 9, and can switch between the first position and the second position. When the guide hopper 7 is in the second position, the guide hopper 7 can be stored and hidden in the frame 1.

[0033] Optionally, a positioning pin 10 is further provided on the connection part 7-1, and a positioning socket is provided on the guide hopper mounting beam 1-1. After the positioning pin 10 passes through the positioning pin hole on the connection part 7-1, the top can be inserted into the positioning socket on the guide hopper mounting beam 1-1. At this time, the guide hopper 7 cannot rotate due to the restriction of the cooperation between the positioning pin 10 and the positioning socket. The guide hopper mounting beam 1-1 of this embodiment is provided with two positioning sockets: a first positioning socket 1-1a and a second positioning socket 1-1b, which are respectively used to position the guide hopper 7 when it is rotated to the first position and the second position, so that the guide hopper 7 remains stable when it is rotated out of the frame 1 or rotated into the frame 1.

[0034] An elastic member 11 is provided between the positioning pin 10 and the connecting portion 7-1. The elastic member 11 of the present embodiment is a spring sleeved outside the positioning pin 10, and its two ends are respectively fixedly connected to the bottom of the positioning pin 10 and the bottom side of the connecting portion 7-1. The elastic member 11 provides the positioning pin 10 with a force to move the positioning pin 10 upward, so that the positioning pin 10 can remain inserted in the positioning socket when there is no external force. For example, when the guide hopper 7 rotates to the first position, the guide hopper 7 is located below the discharge channel 6, and the dialysis powder can be discharged into the container through the guide hopper 7 and the discharge pipe 8. At this time, the top of the positioning pin 10 is inserted into the first positioning socket 1-1a, and the guide hopper 7 cannot rotate, which can avoid the force of discharging the dialysis powder during the weighing process or the guide hopper 7 being rotated and deviated due to accidental contact by personnel, thereby affecting the final weighing accuracy of the dialysis powder. When the guide hopper 7 is not needed, the guide hopper 7 is rotated to the second position, the guide hopper 7 is located inside the frame, and the space occupied is reduced. At this time, the top of the positioning pin 10 is inserted into the second positioning socket 1-1b, and the guide hopper 7 cannot be rotated. When the guide hopper 7 is to be rotated, the positioning pin 10 is pulled downward, the positioning pin 10 overcomes the force of the elastic member 11, and the top withdraws from the positioning socket, breaking away from the positioning of the positioning socket, and the guide hopper 7 can be rotated.

[0035] Furthermore, a rubber buffer block 12 is provided on the top of the positioning pin 10. The rubber buffer block 12 is in a truncated cone structure with a narrow end facing upwards, which can be easily inserted into the positioning socket. Since the positioning pin 10 and the guide hopper mounting beam 1-1 are both made of rigid materials, the rubber buffer block 12 with a buffering effect is provided. When the positioning pin 10 is inserted into the positioning socket, the impact force is small due to the soft contact of the rubber buffer block 12, which can prevent the positioning pin 10 from causing impact damage to the guide hopper mounting beam 1-1.

[0036] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
