The cleaning barrel is arranged on the inner side of the lower barrel, and a lifting and adjusting mechanism is arranged on the inner side of the cleaning barrel, and the lifting and adjusting mechanism is connected to the top plate.

[0007] Preferably, three groups of support springs are provided, and the support springs are distributed in an annular array between the support springs and the bearing plate.

[0008] Preferably, the hopper is fixedly connected to the first connecting plate, and the first connecting plate is snap-connected to the second connecting plate.

[0009] Preferably, the first connecting plate and the second connecting plate are longitudinally threaded with connecting pieces, and the connecting pieces are distributed in a ring array at the connection between the first connecting plate and the second connecting plate, and nuts are connected to both ends of the connecting pieces.

[0010] Preferably, the lifting and adjusting mechanism includes a sleeve, a drain pipe, a water inlet pipe, an adjusting ball, a first conveying pipe, a second conveying pipe, a heat exchange pipe and a liquid pump, and the interior of the sleeve is connected to the drain pipe, and a water inlet pipe is provided on one side of the drain pipe.

[0016] Compared with the prior art, the beneficial effects of the present invention are: the solution flow rate automatic control device,

[0017] (1) The present invention can effectively solve the problem that the regulating nodes of the existing solution flow rate control device are mostly narrow for the convenience of control, so that after long-term use, the high-temperature solution is likely to cool and adhere to the inner wall of the device and then block the regulating port. The heat exchange medium in the heat exchange tube will advance in a spiral shape along the outer wall of the injection pipe under the drive of the liquid pump. During the advancement, it will exchange heat with the high-temperature solution inside the injection pipe. After absorbing heat, the heat exchange medium will be transported to the inside of the water inlet pipe through the second delivery pipe, and flow into the inside of the sleeve and the regulating ball through the through hole at the bottom of the water inlet pipe, so as to heat the sleeve and the regulating ball, and then the cooling solution attached to the cleaning cylinder can be heated by the regulating ball to melt it, thereby avoiding clogging the device and affecting the normal operation of the regulation. In addition, the heat of the solution itself is collected to clean the adhered waste, which is convenient for optimizing the device structure and improving the thermal energy utilization rate.

[0018] (2) The present invention can effectively solve the problem that most of the existing solution flow rate control devices use hydraulic cylinders and linear motor drive devices to adjust the flow rate, which is complex in structure and high in cost by using the liquid level sensor and the warning light. The staff can adjust the weight of the sleeve by injecting heat exchange medium into the sleeve. When the liquid level of the heat exchange medium inside is high, the weight of the sleeve increases, that is, the pressure on the support spring becomes larger, thereby causing the position of the adjustment ball in the discharge barrel to move downward. The greater the downward distance, the smaller the gap between the adjustment ball and the cleaning barrel, that is, the smaller the solution flow rate and flow rate. At the same time, the staff can monitor the liquid level inside the sleeve through the liquid level sensor. When the liquid level reaches the set value and the flow rate of the solution reaches the required value, the liquid level sensor will transmit this information to the controller. The controller will control the warning light to light up to signal the staff to stop injecting heat exchange medium into the sleeve. At the same time, when the heat exchange medium is circulated and heat exchanged subsequently, the flow rate of the solution will not change because the liquid inlet and outlet speeds are equal.

[0019] (3) The present invention can effectively solve the problem that most of the existing device structures are integrated, that is, when a part is damaged or a problem occurs, it needs to be replaced as a whole, and the maintenance cost is high, through the coordinated use of the first connecting plate, the second connecting plate, the connecting piece and the cleaning cylinder. The staff can separate the first connecting plate and the second connecting plate by disassembling the connecting piece, and then manually separate the split cleaning cylinder, so that the device can be separated into four parts, and then the first connecting plate, the second connecting plate or the cleaning cylinder in direct contact with the solution can be replaced or cleaned in a targeted manner, thereby improving the rationality of the device structure and reducing the maintenance cost of the device.

[0027] See also Figure 1-5 The present invention provides a technical solution: a solution flow rate automatic control device, embodiment 1

[0028] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the top plate 1 is arranged above the supporting plate 3, and the top plate 1 is connected to the supporting plate 3 through the supporting spring 2. The supporting plate 3 is arranged on the top of the hopper 4, and the bottom of the hopper 4 is connected with the first connecting plate 5, the bottom of the first connecting plate 5 is connected with the second connecting plate 6, and the lower part of the second connecting plate 6 is provided with a lower barrel 8, the cleaning barrel 10 is arranged on the inner side of the lower barrel 8, and the inner side of the cleaning barrel 10 is provided with a lifting and adjusting mechanism 9, and the lifting and adjusting mechanism 9 is connected to the top plate 1.

The support springs 2 serve to assist in supporting the lifting and adjusting mechanism 9, and then the position of the lifting and adjusting mechanism 9 is adjusted up and down by subsequently increasing the water level, that is, the weight, that is, the flow rate of the solution is adjusted and controlled.

[0030] In a further embodiment, the hopper 4 is fixedly connected to the first connecting plate 5 , and the first connecting plate 5 is snap-connected to the second connecting plate 6 .

[0031] In a further embodiment, a connector 7 is threadedly connected longitudinally through the first connecting plate 5 and the second connecting plate 6, and the connectors 7 are distributed in a circular array at the connection between the first connecting plate 5 and the second connecting plate 6, and nuts are connected at both ends of the connector 7.

[0032] In a further embodiment, the cleaning cylinders 10 are snap-connected with each other, and the cleaning cylinders 10 are fixedly connected to the second connecting plate 6. At the same time, the cleaning cylinders 10 are enclosed in a funnel shape. The setting of the cleaning cylinders 10 prevents the solution from directly contacting the device, thereby preventing the solution from adhering to its side walls. The split cleaning cylinder 10 is convenient for the staff to disassemble and clean it.

[0033] Specifically, in the actual working process, the cleaning cylinder 10 is first snapped together and placed inside the discharge barrel 8, and then the first connecting plate 5 and the second connecting plate 6 are connected through the connecting piece 7, and then the injection pipe 11 is connected to the external conveying equipment, and then the device is started to drive the lifting and adjusting mechanism 9 to adjust and set the flow rate of the solution, and then the solution is injected into the interior of the hopper 4 through the injection pipe 11. The solution entering the interior of the hopper 4 will be discharged through the discharge barrel 8 after being adjusted by the lifting and adjusting mechanism 9.

[0034] Example 2

[0035] This embodiment is a further description of the above embodiment. It should be understood that this embodiment includes all the above technical features and is further described in detail.

[0036] like Figure 1 、 Figure 3 、 Figure 4 and Figure 5As shown, in a further embodiment, the lifting and adjusting mechanism 9 includes a sleeve 901, a drain pipe 902, a water inlet pipe 903, an adjusting ball 904, a first conveying pipe 905, a second conveying pipe 906, a heat exchange pipe 907 and a liquid pump 908, and the interior of the sleeve 901 is connected to the drain pipe 902, and a water inlet pipe 903 is provided on one side of the drain pipe 902, the drain pipe 902 is connected to one end of the liquid pump 908 through the first conveying pipe 905, and the other end of the liquid pump 908 is connected to one end of the heat exchange pipe 907, and the other end of the heat exchange pipe 907 is connected to the other end of the heat exchange pipe 907, the heat exchange pipe 907 is wrapped around the liquid injection pipe 11, and the liquid injection pipe 11 is arranged through the interior of the liquid injection port 14, and the liquid injection port 14 is opened on the outer wall of the hopper 4.

[0037] In a further embodiment, the sleeve 901 is disposed through the center of the top plate 1 , and the sleeve 901 is slidably connected to the supporting plate 3 .

[0038] In a further embodiment, a liquid level sensor 12 is installed on the outer wall of the water inlet pipe 903 , and the liquid level sensor 12 is electrically connected to the controller and the warning light 13 , and the warning light 13 is installed on the outer wall of the hopper 4 .

[0039] In a further embodiment, the outer wall of the regulating ball 904 contacts the inner wall of the cleaning cylinder 10 , and the cleaning cylinder 10 is symmetrically arranged inside the discharge cylinder 8 .

[0040] In a further embodiment, the bottom ends of the first delivery pipe 905 and the second delivery pipe 906 are both connected to the interior of the adjustment ball 904 , and the adjustment ball 904 is fixedly connected to the bottom of the sleeve 901 .

[0041] Specifically, in the actual working process, the staff can inject the heat exchange medium into the interior of the sleeve 901, and then adjust the weight of the sleeve 901. When the heat exchange medium level inside is high, the weight of the sleeve 901 increases, that is, the pressure on the support spring 2 becomes larger, thereby causing the adjustment ball 904 to move downward in the discharge barrel 8. The greater the downward distance, the smaller the gap between the adjustment ball 904 and the cleaning barrel 10, that is, the smaller the flow rate and flow velocity of the solution. After the adjustment is completed in the actual use process, the solution entering the hopper 4 flows downward through the gap between the adjustment ball 904 and the cleaning barrel 10, thereby realizing flow regulation. At the same time, the staff can monitor the liquid level inside the sleeve 901 through the liquid level sensor 12. When the liquid level reaches the set value and the flow velocity of the solution reaches the required value, the liquid level sensor 12 is used. 12 will pass this information to the controller, and the controller will control the warning light 13 to light up to signal the staff to stop injecting the heat exchange medium into the sleeve 901, and then it will advance in a spiral shape along the outer wall of the injection pipe 11 under the drive of the liquid pump 908. In the process of advancing, it will exchange heat with the high-temperature solution inside the injection pipe 11. The heat exchange medium after absorbing heat will be transported to the inside of the water inlet pipe 903 through the second delivery pipe 906, and flow into the inside of the sleeve 901 and the adjusting ball 904 through the through hole at the bottom of the water inlet pipe 903, so that the sleeve 901 and the adjusting ball 904 can be heated, and then the solution attached to the cleaning cylinder 10 that has been cooled after the device is used can be heated by the adjusting ball 904 to melt it, thereby avoiding clogging the device and affecting the normal progress of the adjustment work.
