DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 4 The utility model provides a technical solution: a discharging control device, including a discharging pipe 1, a pneumatic powder butterfly valve 2 is installed at the bottom end of the discharging pipe 1, a solid particle flow meter 3 is installed at the bottom end of the pneumatic powder butterfly valve 2, a material receiving pipe 7 is provided below the solid particle flow meter 3, and the material receiving pipe 7 is connected to the solid particle flow meter 3 through a docking component, and the docking component includes: a rubber folding soft cylinder 4, the rubber folding soft cylinder 4 is fixedly connected to the bottom end of the solid particle flow meter 3, the bottom end of the rubber folding soft cylinder 4 is fixedly connected to a circular groove plate 5, and the circular groove plate 5 A vertical cylinder 6 is fixedly connected to the inner top end, a first cavity ring 8 is fixedly connected to the outer wall of the vertical cylinder 6, a second cavity ring 9 is fixedly connected to the inner wall of the circular groove plate 5, a first solenoid valve 10 is fixedly connected to one side of the top end of the circular groove plate 5, a positive pressure pipe 11 is connected to the top end of the first solenoid valve 10, a second solenoid valve 12 is fixedly connected to the other side of the top end of the circular groove plate 5, a negative pressure pipe 13 is connected to the top end of the second solenoid valve 12, handles 14 are fixedly connected to the front and back sides of the outer wall of the circular groove plate 5, and the first cavity ring 8 and the second cavity ring 9 are tightly pressed against the material receiving pipe 7 after the volume is expanded.

[0023] In the specific implementation process, it is worth pointing out that the top of the discharge pipe 1 is connected to the external zirconium tetrachloride condensation material tank, and the pneumatic powder butterfly valve 2 is mainly used to switch the material box, hopper and silo filled with powdered or granular materials. Its structure makes it perform well in powder-specific transportation and is suitable for the processing of all powdered and granular materials. The working principle of the solid particle flowmeter 3 is based on the contact electrification theory of solid materials. The powder material will accumulate a certain degree of charge during the movement. When the powder material passes through the annular sensor of the flowmeter, each charged powder particle signal passing through the annular sensor is effectively captured, amplified, shaped and filtered by the amplifier circuit, and handed over to the high-speed processor for calculation. It can output a standard current signal that is linearly related to the powder flow, and finally converted into a numerical value (kg / H or T / H), which is suitable for a variety of powder media, The on-line flow monitoring of solid particulate materials can be widely used in the electric power, metallurgy, cement, pharmaceutical, chemical, food manufacturing and other industries. The material receiving pipe 7 is a material receiving pipe used for receiving materials in storage and transportation tanks. The rubber folding soft tube 4 is made of rubber material and can be compressed and deformed. The first cavity ring 8 and the second cavity ring 9 are both made of rubber material and have a certain flexibility. When the internal air pressure increases, the volume can expand, and when the internal air pressure decreases, the volume can be restored. Of course, the volume can shrink when the internal pressure is negative. The first solenoid valve 10 and the second solenoid valve 12 are both normally closed solenoid valves. Their power lines are connected to the external power supply device to provide the required power for their operation. The positive pressure pipe 11 is connected to the external high-pressure air supply device, and the negative pressure pipe 13 is connected to the external air adsorption device. The handle 14 can facilitate the user to apply force to the circular groove plate 5.

[0024] Furthermore, pressure relief valves 19 are fixedly connected to the left and right sides of the outer wall of the circular groove plate 5 , and the air inlet port of the pressure relief valve 19 is communicated with the interior of the second cavity ring 9 .

[0025] During the specific implementation process, it is worth pointing out that a spring and piston system (or valve core) is usually provided inside the pressure relief valve 19. When the system pressure exceeds the preset value, the pressure will overcome the resistance of the spring and push the piston or valve core to move, thereby opening the valve and releasing excess pressure. When the first solenoid valve 10 is not closed in time due to operational errors, the internal air pressure of the first cavity ring 8 and the second cavity ring 9 is greater than the set critical value of the pressure relief valve 19. The pressure relief valve 19 can discharge the internal air of the first cavity ring 8 and the second cavity ring 9 to the outside, thereby preventing the first cavity ring 8 and the second cavity ring 9 from being damaged due to the high internal air pressure, thereby facilitating long-term and safe use.

[0026] Furthermore, an auxiliary component is provided above the first cavity ring 8 and the second cavity ring 9, and the auxiliary component includes: a circular ring 15, the circular ring 15 is located above the first cavity ring 8 and the second cavity ring 9, a transverse tube 17 is provided above the circular ring 15, the left and right ends of the transverse tube 17 are respectively fixedly connected to the first cavity ring 8 and the second cavity ring 9, and the outer wall of the transverse tube 17 is provided with a support plate 16, and the upper and lower ends of the support plate 16 are respectively fixedly connected to the circular groove plate 5 and the material receiving tube 7.

[0027] In the specific implementation process, it is worth pointing out that the interior of the cross tube 17 is interconnected with the interior of the first cavity ring 8 and the second cavity ring 9. After the setting of the cross tube 17, the cross tube 17 can make the interiors of the first cavity ring 8 and the second cavity ring 9 in a state of mutual communication, so that the internal air pressures of the first cavity ring 8 and the second cavity ring 9 can be the same, so that the first cavity ring 8 and the second cavity ring 9 have the same force strength on the connecting pipe 7, which facilitates the connecting pipe 7 to be in a stable state after being connected. The outer wall of the cross tube 17 and the through surface of the support plate 16 are clearance matched, and the clearance match refers to a match with a gap (including a minimum gap equal to zero).

[0028] Furthermore, a plurality of transverse tubes 17 are provided, and the plurality of transverse tubes 17 are distributed above the ring 15 in an annular shape and at equal intervals.

[0029] In the specific implementation process, it is worth pointing out that during the injection of high-pressure air into the second cavity ring 9, the internal air pressures of the first cavity ring 8 and the second cavity ring 9 can be quickly brought into the same state.

[0030] Furthermore, the transverse tube 17 is a double-section structure, and a rubber folding tube 18 is fixedly connected between the double-section transverse tubes 17 .

[0031] During the specific implementation process, it is worth pointing out that the rubber folding tube 18 is made of rubber material and has a certain flexibility, which can change the distance between the double-section cross tube 17 and facilitate sufficient tightening between the first cavity ring 8 and the second cavity ring 9 and the receiving tube 7.

[0032] Working principle:

[0033] Installation of the material connection pipe for the storage tank:

[0034] The user first places the receiving pipe 7 for receiving materials from the storage tank under the circular groove plate 5, and applies force to the handle 14 to fit the circular groove plate 5 on the outer wall of the receiving pipe 7, so that the first cavity ring 8 and the second cavity ring 9 are respectively located on the inner and outer sides of the pipe wall of the receiving pipe 7. At this time, the first solenoid valve 10 is opened and closed, and the positive pressure pipe 11 begins to inject air higher than atmospheric pressure into the first cavity ring 8 and the second cavity ring 9 through the first solenoid valve 10. The internal air pressure of the first cavity ring 8 and the second cavity ring 9 increases, and the volume expands accordingly, counteracting the receiving pipe 7. Then the first solenoid valve 10 is closed to complete the docking operation of the receiving pipe 7 for receiving materials from the storage tank. In this process, the receiving port of the storage tank and the discharge port of zirconium tetrachloride are connected simply and efficiently.

[0035] Feeding operations into storage tanks:

[0036] The powder butterfly valve 2 is started to be opened and closed, and the bottom end of the discharge pipe 1 is in an open state. The material is injected into the storage tank through the pneumatic powder butterfly valve 2, the solid particle flow meter 3, the rubber folding soft cylinder 4, the vertical cylinder 6 and the receiving pipe 7 in sequence. During this period, the solid particle flow meter 3 can accurately measure the flow rate of the passing material, so as to accurately know the amount of material loaded into the tank body, without the need to judge by knocking, and it is not easy to overflow and be incomplete. After the material discharge amount reaches the standard, the pneumatic powder butterfly valve 2 is closed, and the second solenoid valve 12 is started. The negative pressure pipe 13 can extract most of the air inside the first cavity ring 8 and the second cavity ring 9. The air pressure inside the first cavity ring 8 and the second cavity ring 9 is reduced and the volume is reduced accordingly. The first cavity ring 8 and the second cavity ring 9 no longer press against the discharge pipe 7. At this time, the circular groove plate 5 can be removed from the top of the receiving pipe 7 to complete the overall feeding operation.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
