Description

Technical Field

[0001] This invention belongs to the field of building material production equipment, specifically a multi-outlet feeding device and its sealing structure. Background Technology

[0002] With the continuous improvement of engineering quality, environmental protection and civilized construction requirements, the shortcomings and limitations of on-site mortar mixing are becoming more and more prominent. Dry-mixed mortar is gaining more and more favor due to its advantages in technical performance and social benefits. Dry-mixed mortar mixing equipment has been developing rapidly in recent years, resulting in many new technologies and functional modules.

[0003] After mixing, dry-mixed mortar is transferred to finished product tanks via various conveying mechanisms. From there, it is loaded onto bulk trucks and transported to the construction site. Due to the wide variety of dry-mixed mortar products and considering factors such as equipment costs, most dry-mixed mortar manufacturers produce different types of dry-mixed mortar using the same mixer by adjusting the production formula. In existing technologies, reversing valves are often used to transport mortars of different formulas to different finished product tanks. However, the reversing valves may retain mortar of the previous formula, leading to cross-contamination of the finished dry-mixed mortar products. Furthermore, repairing or replacing the reversing valves when they malfunction is difficult and requires improvement. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a multi-outlet feeding device and its sealing structure.

[0005] The present invention adopts the following technical solution:

[0006] A multi-outlet feeding device and its sealing structure include multiple feed pipes spaced apart, an outlet pipe movably disposed above the multiple feed pipes and selected to be opposite to one of the feed pipes, a driving component connected to and driving the outlet pipe to move opposite to one of the feed pipes, and a rubber sealing ring disposed at the opposite end of the feed pipe and the outlet pipe. When the outlet pipe is opposite to the feed pipe, the lower end of the outlet pipe squeezes the rubber sealing ring to make the outlet pipe and the feed pipe in a sealed state.

[0007] Preferably, the rubber sealing ring includes a connecting section and a sealing section sleeved on the end of the feed pipe. The sealing section is inclined inward and disposed at the upper end of the connecting section. When the discharge pipe is opposite to the feed pipe, the lower end of the discharge pipe presses the sealing section downward to make the discharge pipe and the feed pipe in a sealed state.

[0008] Preferably, the distance between the upper end of the sealing section and the upper end of the discharge pipe is greater than the distance between the upper end of the feed pipe and the lower end of the discharge pipe.

[0009] Preferably, the top of the feed pipe extends outward to form a first outer edge, and the connecting section of the rubber sealing ring is sleeved on the first outer edge.

[0010] Preferably, the bottom of the discharge pipe extends outward to form a second outer edge. When the discharge pipe is opposite to the inlet pipe, the second outer edge presses down on the rubber sealing ring sealing section to make the discharge pipe and the inlet pipe in a sealed state.

[0011] Preferably, the lower end of the second outer edge is provided with a chamfer that mates with the sealing section.

[0012] Preferably, the inner diameter of the upper end of the sealing section of the rubber sealing ring is smaller than the diameter of the second outer edge and larger than the inner diameter of the discharge pipe.

[0013] Preferably, the discharge pipe is rotatably disposed above the feed pipe, and multiple feed pipes are circumferentially distributed. The discharge pipe includes a feed section connected to the mixer at its upper end, an inclined section disposed at the bottom of the feed section and inclined outward, and a discharge section disposed at the bottom of the inclined section and opposite to the feed pipe.

[0014] Preferably, the discharge pipe is movable and positioned above the feed pipe, and multiple feed pipes are arranged at intervals along the direction of movement.

[0015] A multi-outlet feeding device includes a mixer for mixing materials, a plurality of storage tanks spaced apart, and a sealing structure as described above disposed between the mixer and the plurality of storage tanks. The plurality of feed pipes correspond one-to-one with the plurality of storage tanks, and the discharge pipes are connected to the mixer.

[0016] As can be seen from the above description of the present invention, compared with the prior art, the beneficial effects of the present invention are: the discharge pipeline can be movably installed on different storage tanks, and dry-mixed mortars of different formulations can be transported to different storage tanks for storage, so that one mixer can mix multiple formulations of dry-mixed mortar, which greatly saves costs. In addition, by setting a rubber sealing ring at one end of the feed pipeline and the discharge pipeline to seal the gap that exists when the feed pipeline and the discharge pipeline are opposite, the mortar is in a sealed transportation space, preventing the dry-mixed mortar from overflowing from the gap during transportation and causing leakage and environmental pollution.

[0017] The rubber sealing ring is sleeved on the feed pipe through the connecting section, which is convenient to disassemble and assemble. When the rubber sealing ring is damaged, it can be replaced in time. The sealing section is set at the upper end of the connecting section with the discharge pipe to seal the transport space. It does not affect the movement of the discharge pipe and can also play a sealing role.

[0018] The distance between the upper end of the sealing section and the upper end of the discharge pipe is greater than the distance between the upper end of the inlet pipe and the lower end of the discharge pipe. When the discharge pipe moves to the inlet pipe, the discharge pipe presses down on the sealing section of the rubber sealing ring, so that the discharge pipe fits with the sealing section to achieve the sealing effect.

[0019] The lower end of the second outer edge is provided with a chamfer that matches the sealing section. This can prevent the discharge pipe from lifting the rubber sealing ring during movement, thus preventing leakage. It can also prevent the right-angled edge from cutting the rubber sealing ring, thus damaging the rubber sealing ring and affecting the sealing effect.

[0020] The inner diameter of the upper end of the rubber sealing ring sealing section is smaller than the diameter of the second outer edge and larger than the inner diameter of the discharge pipe. When the discharge pipe moves to the inlet pipe, the upper end of the sealing section is always located within the second outer edge to ensure smooth mortar delivery. Attached Figure Description

[0028] The present invention will be further described below through specific embodiments.

[0029] Reference Figures 1 to 6 As shown, a multi-outlet feeding device and its sealing structure are installed between a mixer and multiple storage tanks, including a feed pipe 1, a discharge pipe 2, a drive component, and a rubber sealing ring 3.

[0030] The feed pipe 1 is installed on the storage tank to transport dry-mixed mortar into the storage tank. There are multiple feed pipes 1, which are installed on the top of multiple storage tanks respectively.

[0031] The discharge pipe 2 can be movably positioned above multiple feed pipes 1, and can be selected to be opposite to one feed pipe 1 to transport the mixture in the mixer to the corresponding storage tank. Specifically, when the discharge pipe 2 is rotatably positioned above the feed pipes 1, referring to the first embodiment of this application, the multiple feed pipes 1 are distributed circumferentially, and the discharge pipe 2 includes a feed section 21 connected to the mixer at its upper end, an inclined section 22 located at the bottom of the feed section 21 and inclined outward, and a discharge section 23 located at the bottom of the inclined section 22 and opposite to the feed pipe 1. When the discharge pipe 2 can be moved back and forth above the feed pipes 1, referring to the second embodiment of this application, the multiple feed pipes 1 are arranged at intervals along the direction of movement, and the discharge pipe 2 is a vertically positioned pipe. The movably positioned discharge pipe 2 transports dry-mixed mortars of different formulations to different storage tanks, enabling one mixer to mix multiple dry-mixed mortars, which greatly saves costs.

[0032] The driving component connects to and drives the discharge pipe 2 to rotate or move back and forth. Specifically, the driving component is a commonly used driving device in transfer engineering machinery that can drive components to rotate or move back and forth, such as a servo motor or cylinder. The specific selection of the driving device is not the point of invention of this application, and its specific selection and structure will not be further described here.

[0033] A rubber sealing ring 3 is installed on the end of the feed pipe 1 opposite to the discharge pipe 2. The rubber sealing ring 3 includes a connecting section 31 and a sealing section 32 sleeved on the end of the feed pipe 1. The sealing section 32 is inclined inward from the upper end of the connecting section 31. The lower section of the discharge pipe 2 presses the rubber sealing ring 3 downward to make the discharge pipe 2 and the feed pipe 1 in a sealed state. Specifically, the distance between the upper end of the sealing section 32 and the upper end of the discharge pipe 2 is greater than the distance between the upper end of the feed pipe 1 and the lower end of the discharge pipe 2. When the discharge pipe 2 moves onto the feed pipe 1, the discharge pipe 2 presses the sealing section 32 of the rubber sealing ring 3 downward to make the discharge pipe 2 fit with the sealing section 32, thereby achieving the sealing effect.

[0034] The feed pipe 1 includes a guide section 11 and a conveying section 12. The guide section 11 is located at the upper end of the conveying section 12, opposite to the discharge pipe 2. The guide section 11 has a constricted structure that is wider at the top and narrower at the bottom, guiding the mortar from the conveying section 12 into the storage tank. The top of the guide section 11 extends outward to form a first outer edge 13, which is specifically a circular ring plate welded to the top of the guide section 11. The connecting section 31 of the rubber sealing ring 3 is sleeved on the first outer edge 13. Correspondingly, the bottom of the discharge pipe 2 extends outward to form a second outer edge 24, which is specifically a circular ring plate welded to the bottom of the discharge pipe 2. The second outer edge 24 presses the rubber sealing ring 3 downward. The sealing section 32 ensures a sealed connection between the discharge pipe 2 and the inlet pipe 1. Specifically, the lower end of the second outer edge 24 is provided with a chamfer 25 that mates with the sealing section 32. This prevents the discharge pipe 2 from lifting the rubber sealing ring 3 during movement, thus preventing leakage. It also prevents the right-angled edge from cutting the rubber sealing ring 3 and damaging it, thus affecting the sealing effect. Furthermore, the inner diameter of the upper end of the sealing section 32 is smaller than the diameter of the second outer edge 24 and larger than the inner diameter of the discharge pipe 2. When the discharge pipe 2 moves onto the inlet pipe 1, the upper end of the sealing section 32 is always located within the second outer edge 24, ensuring the smooth delivery of mortar.

[0035] This application allows the discharge pipe 2 to be movably connected to different storage tanks, enabling the delivery of dry-mixed mortars with different formulations to the corresponding storage tanks. This allows one mixer to mix multiple formulations of dry-mixed mortar, greatly saving costs. Furthermore, by setting a rubber sealing ring at one end of the feed pipe 1 opposite to the discharge pipe 2, the gap between the feed pipe 1 and the discharge pipe 2 is sealed. The rubber sealing ring 3 also seals the transport space, keeping the mortar in a sealed transport space and preventing the dry-mixed mortar from overflowing from the gap during transport and causing leakage and environmental pollution.

[0036] The above description is merely a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the specification of the present invention should still fall within the scope of the patent of the present invention.
