[0002] When an operator prepares sodium carbonate, a forklift is used to suspend a bag of sodium carbonate directly above the preparation tank. The operator uses a knife to cut open the bag and pour the sodium carbonate into the preparation tank. Sodium carbonate is in a small-particle solid state and is extremely easy to disperse into the air, causing environmental pollution; the dust floating everywhere is easily inhaled by the operator and surrounding personnel, causing health hazards to the lungs, respiratory system, etc. of the personnel; there are certain safety hazards due to the dispersion of dust particles. Summary of the Utility Model

[0003] In order to overcome the problem of powder diffusion when the powder is poured into the preparation tank in the above technical solution, the utility model provides a powder anti-diffusion device for a preparation tank, which can prevent the powder from diffusing outside the preparation tank.

[0004] To solve the above technical problems, the technical solution adopted by the utility model is: a powder anti-diffusion device for a preparation tank, including a cover plate for covering the tank opening of the preparation tank, a puncturing member installed on the cover plate, and a spraying component arranged around the outer edge of the cover plate; the cover plate is provided with a plurality of through parts; the liquid spraying direction of the spraying component is upward.

[0005] In the above technical solution, the cover plate is covered on the preparation tank. A forklift is used to suspend the bag containing sodium carbonate directly above the puncturing member. The spraying component is turned on, so that the liquid sprayed by the spraying component forms a water curtain at the outer edge of the cover plate. The forklift is commanded to lower the bag containing sodium carbonate, and the puncturing member is commanded to pierce the bag, so that the sodium carbonate flows out of the bag and enters the preparation tank through the through parts of the cover plate. Due to the shielding of the water curtain, the sodium carbonate cannot diffuse outside the water curtain when flowing out.

[0006] Preferably, the spraying component includes a connecting pipe for connecting to a water source and a spraying pipe connected to the connecting pipe. A plurality of water outlet holes are arranged on the spraying pipe, and the openings of the water outlet holes are upward. The spraying pipe is arranged around the outer edge of the cover plate; a valve is installed on the connecting pipe. The valve can be an electromagnetic valve or an electric valve, which can be opened remotely, so that the forklift operator or the backstage personnel can open it according to the conveying situation of the forklift. The connecting pipe can be connected to a water supply system, and tap water is sprayed upward from the water outlet holes to form a water curtain through conventional water pressure. If the pressure is considered insufficient, a water pump can be added at the connecting pipe. The spraying pipe can be a rigid plastic pipe, a rigid metal pipe or a soft plastic pipe. If a rigid pipe is used, the spraying pipe will enclose the cover plate. If a soft plastic pipe is used, it will be arranged along the outer edge of the cover plate.

[0007] Preferably, nozzles are provided at the water outlet holes. Hard plastic pipes or hard metal pipes can be used to install nozzles at the water outlet holes, increasing the spraying diameter of a single water outlet hole and expanding the coverage range of the water curtain.

[0008] Preferably, the spray pipe is a flexible pipe.

[0009] Preferably, the water outlet holes are equidistantly arranged on the spray pipe, and the spraying diameter of the water outlet holes is greater than the distance between two adjacent water outlet holes. The water sprayed from adjacent water outlet holes can cover the distance between them, thereby forming a water curtain without gaps to prevent powder from overflowing.

[0010] Preferably, the spray pipe is bound to the cover plate by a wire, reducing the installation difficulty between the spray pipe and the cover plate.

[0011] Preferably, the cover plate is in a grid shape, and the piercing member is fixed at the intersection of the horizontal and vertical lines of the grid of the cover plate. The cover plate in a grid shape has the through part as the grid, which is formed by the intersection of multiple horizontal bars and multiple vertical bars. The piercing member is arranged at the intersection of the horizontal and vertical bars. When the piercing member bears the gravity of the bag, the cover plate is not easily deformed.

[0012] Preferably, multiple piercing members are provided and are all located near the center of the cover plate. The forklift moves the bag above the piercing member, that is, the bag is located at the center of the cover plate. In this way, sodium carbonate can enter the preparation tank better, and at the same time, less powder overflows to the edge of the cover plate, avoiding a large amount of powder overflowing to the edge of the cover plate and breaking through the barrier of the water curtain.

[0013] Preferably, the piercing member is welded to the cover plate, and welding can increase the connection strength between the two to prevent the piercing member from detaching from the cover plate.

[0014] Preferably, the piercing member is a three-sided thorn. The three-sided thorn has a good piercing effect. It can pierce the bag when the bag falls, and at the same time, it can expand the opening at the pierced position of the bag through the edges, making the powder flow out of the bag faster.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: The operator transports the bag on the forklift and the piercing member can pierce the bag, eliminating the need for staff to cut the bag closely, avoiding contact between the staff and the powder. At the same time, the water curtain formed by the spraying assembly isolates the powder within the range of the cover plate, preventing the powder from spreading into the external air and avoiding the staff from inhaling the powder.

[0023] Embodiment 1

[0024] As shown in FIGS. Figure 1 and 2 , Embodiment 1 of a powder anti-diffusion device for a preparation tank includes a cover plate 1 for covering the opening of the preparation tank, a piercing member 2 installed on the cover plate 1, and a spraying assembly 3 disposed around the outer edge of the cover plate 1; the cover plate 1 is provided with a plurality of through portions 101; the liquid spraying direction of the spraying assembly 3 is upward.

[0025] ​​​​The spraying assembly 3 includes a connecting pipe 301 for connecting to a water source and a spraying pipe 302 connected to the connecting pipe 301. A number of water outlet holes 303 are provided on the spraying pipe 302, and the openings of the water outlet holes 303 face upward. The spraying pipe 302 is arranged around the outer edge of the cover plate 1; a valve is installed on the connecting pipe 301. The valve can be an electromagnetic valve or an electric valve, which can be opened remotely, allowing the forklift operator or the backstage personnel to open it according to the conveying situation of the forklift. The connecting pipe 301 can be connected to a water supply system, and tap water can be sprayed upward from the water outlet holes 303 to form a water curtain through conventional water pressure. If insufficient pressure is considered, in some embodiments, a water pump can be added at the connecting pipe 301.

[0026] In this embodiment, the spraying pipe 302 is a rigid plastic pipe, and nozzles 304 are provided at the water outlet holes 303. By using a rigid plastic pipe or a rigid metal pipe, nozzles 304 can be installed at the water outlet holes 303 to increase the spraying diameter of a single water outlet hole 303 and expand the coverage range of the water curtain. The water outlet holes 303 are equidistantly arranged on the spraying pipe 302, and the spraying diameter of the water outlet holes 303 is greater than the distance between two adjacent water outlet holes 303. The water sprayed from two adjacent water outlet holes 303 can cover the distance between them, thereby forming a water curtain without gaps to prevent powder from spilling out. In this embodiment, the distance between two adjacent water outlet holes 303 is 30 cm.

[0027] In some different embodiments, the water outlet of the nozzle 304 can be vertically oriented, or can be inclined toward the center of the cover plate 1 and upward.

[0028] Specifically, the spraying pipe 302 is bound to the cover plate 1 by a wire 4, reducing the installation difficulty between the spraying pipe 302 and the cover plate 1.

[0029] In addition, the cover plate 1 is in a grid shape, and the piercing member 2 is fixed at the intersection of the vertical and horizontal grids of the cover plate 1. For the grid-shaped cover plate 1, the through portion 101 is the grid, which is formed by multiple horizontal bars and multiple vertical bars intersecting vertically and horizontally. The piercing member 2 is arranged at the intersection of the horizontal and vertical bars. When the piercing member 2 bears the gravity of the bag, the cover plate 1 is not easily deformed. The piercing member 2 is welded to the cover plate 1, and the welding can increase the connection strength between the two and prevent the piercing member 2 from detaching from the cover plate 1.

[0030] Working principle of this embodiment: Cover the cover plate 1 on the preparation tank 5. Use a forklift to suspend the bag filled with sodium carbonate directly above the puncturing member 2. Open the valve. Tap water flows from the connecting pipe 301 to the spray pipe 302 and then sprays out from the nozzle 304 of the spray pipe 302. The water sprayed out from the nozzle 304 forms a water curtain at the outer edge of the cover plate 1. Let the forklift lower the bag filled with sodium carbonate, and let the puncturing member 2 puncture the bag. Sodium carbonate flows out of the bag and enters the preparation tank through the through-hole 101 of the cover plate 1. Due to the shielding of the water curtain, sodium carbonate cannot spread outside the water curtain when flowing out.

[0031] Beneficial effects of this embodiment: The operator can transport the bag on the forklift and the puncturing member 2 can puncture the bag, without the need for the staff to cut open the bag closely, avoiding the staff from contacting the powder. At the same time, the water curtain formed by the spray assembly 3 isolates the powder within the range of the cover plate 1, preventing the powder from drifting into the external air and avoiding the staff from inhaling the powder.

[0032] Embodiment 2

[0033] As Figures 3-4 shown in Embodiment 2 of a powder anti-diffusion device for a preparation tank, which includes a cover plate 1 for covering the mouth of the preparation tank, a puncturing member 2 installed on the cover plate 1, and a spray assembly 3 arranged around the outer edge of the cover plate 1; the cover plate 1 is provided with a plurality of through-holes 101; the liquid spraying direction of the spray assembly 3 is upward.

[0034] The spray assembly 3 includes a connecting pipe 301 for connecting to a water source and a spray pipe 302 connected to the connecting pipe 301. A plurality of water outlet holes 303 are provided on the spray pipe 302, and the openings of the water outlet holes 303 face upward. The spray pipe 302 is arranged around the outer edge of the cover plate 1; a valve is installed on the connecting pipe 301. The valve can be an electromagnetic valve or an electric valve, which can be opened remotely, allowing the forklift operator or the backstage personnel to open it according to the transportation situation of the forklift. The connecting pipe 301 can be connected to a water supply system.

[0035] Specifically, the spray pipe 302 is a flexible pipe. The water outlet holes 303 are equidistantly arranged on the spray pipe 302, and the spraying diameter of the water outlet holes 303 is greater than the distance between two adjacent water outlet holes 303. The water sprayed out from two adjacent water outlet holes 303 can cover the distance between them, thus forming a water curtain without gaps to prevent the powder from overflowing. In this embodiment, the distance between two adjacent water outlet holes 303 is 20 cm.

[0036] Specifically, the spray pipe 302 is bound to the cover plate 1 by a wire 4, reducing the installation difficulty between the spray pipe 302 and the cover plate 1.

[0037] Additionally, the cover plate 1 is in a grid shape, and the puncturing member 2 is fixed at the intersection points of the vertical and horizontal grids of the cover plate 1. For the grid-shaped cover plate 1, the through portion 101 is the grid, which is formed by the intersection of multiple horizontal bars and multiple vertical bars. The puncturing member 2 is arranged at the intersection points of the horizontal and vertical bars. When the puncturing member 2 bears the gravity of the bag, the cover plate 1 is not easily deformed. The puncturing member 2 is welded to the cover plate 1, and the welding can increase the connection strength between the two, preventing the puncturing member 2 from detaching from the cover plate 1.

[0038] The working principle of this embodiment: Cover the cover plate 1 on the preparation tank 5, use a forklift to suspend the bag containing sodium carbonate directly above the puncturing member 2, open the valve, tap water flows from the connecting pipe 301 to the spray pipe 302, and then sprays out from the water outlet holes 303 of the spray pipe 302. The water sprayed out from the water outlet holes 303 forms a water curtain at the outer edge of the cover plate 1. Then, use the forklift to lower the bag containing sodium carbonate, so that the puncturing member 2 pierces the bag, and the sodium carbonate flows out of the bag and enters the preparation tank through the through portion 101 of the cover plate 1. Due to the shielding of the water curtain, the sodium carbonate cannot spread outside the water curtain when flowing out.

[0039] The beneficial effects of this embodiment: The operator can transport the bag on the forklift and the puncturing member 2 can pierce the bag, eliminating the need for the staff to cut the bag closely, avoiding contact between the staff and the powder. At the same time, the water curtain formed by the spray assembly 3 isolates the powder within the range of the cover plate 1, preventing the powder from spreading into the external air and avoiding the staff from inhaling the powder.

[0040] Embodiment 3

[0041] An embodiment 3 of a powder anti-diffusion device for a preparation tank, as Figure 3 shown, includes a cover plate 1 for covering the notch of the preparation tank, a puncturing member 2 installed on the cover plate 1, and a spray assembly 3 arranged around the outer edge of the cover plate 1; the cover plate 1 is provided with a number of through portions 101; the liquid spraying direction of the spray assembly 3 is upward.

[0042] The spraying assembly 3 includes a connecting pipe 301 for connecting to a water source and a spraying pipe 302 connected to the connecting pipe 301. A number of water outlet holes 303 are provided on the spraying pipe 302, and the openings of the water outlet holes 303 face upward. The spraying pipe 302 is arranged around the outer edge of the cover plate 1; a valve is installed on the connecting pipe 301. The valve can be a solenoid valve or an electric valve, which can be opened remotely, allowing the forklift operator or the backstage personnel to open it according to the conveying situation of the forklift. The connecting pipe 301 can be connected to a water supply system, and tap water is ejected upward from the water outlet holes 303 to form a water curtain through conventional water pressure. If insufficient pressure is considered, a water pump can be added at the connecting pipe 301. Among them, the spraying pipe 302 can be a rigid plastic pipe, a rigid metal pipe or a flexible plastic pipe. If a rigid pipe is used, the spraying pipe 302 will enclose the cover plate 1. If it is a flexible plastic pipe, it will be arranged along the outer edge of the cover plate 1.

[0043] The cover plate 1 is in a grid shape, and the piercing members 2 are fixed at the vertical and horizontal intersection points of the grid of the cover plate 1. For the grid-shaped cover plate 1, the through portion 101 is the grid, which is formed by multiple horizontal bars and multiple vertical bars intersecting vertically and horizontally. Among them, the piercing members 2 are arranged at the vertical and horizontal intersection points of the horizontal bars and the vertical bars. When the piercing members 2 bear the gravity of the bag, the cover plate 1 is not easily deformed. The piercing members 2 are welded to the cover plate 1, and the welding can increase the connection strength between the two and prevent the piercing members 2 from detaching from the cover plate 1.

[0044] A plurality of piercing members 2 are provided and are all located near the center of the cover plate 1. The forklift moves the bag above the piercing members 2, that is, the bag is located at the center of the cover plate 1. In this way, sodium carbonate can better enter the preparation tank, and at the same time, less powder will spill to the edge of the cover plate 1, avoiding a large amount of powder overflowing to the edge of the cover plate 1 and breaking through the blockage of the water curtain.

[0045] In this embodiment, the piercing member 2 is a three-sided thorn. The three-sided thorn has a good piercing effect. It can pierce the bag when the bag falls, and at the same time, the opening of the position where the bag is pierced can be enlarged through the edges, so that the powder can flow out of the bag faster.

[0046] The working principle of this embodiment: Cover the cover plate 1 on the preparation tank, use the forklift to suspend the bag containing sodium carbonate directly above the piercing members 2, open the valve, tap water flows from the connecting pipe 301 to the spraying pipe 302, and then sprays out from the water outlet holes 303 of the spraying pipe 302. The water sprayed out from the water outlet holes 303 forms a water curtain at the outer edge of the cover plate 1. Let the forklift lower the bag containing sodium carbonate, and let the piercing members 2 pierce the bag, so that sodium carbonate flows out of the bag and enters the preparation tank through the through portion 101 of the cover plate 1. Due to the shielding of the water curtain, sodium carbonate cannot diffuse outside the water curtain when it flows out.
