Description

Technical Field

[0001] This utility model relates to the field of UHPC concrete processing technology, and in particular to a material distributor for UHPC concrete processing. Background Technology

[0002] Ultra-high performance concrete (UHPC) is a new type of building material with ultra-high strength, excellent durability, and good toughness. Its components include cement, silica fume, ultrafine silica sand, and steel fibers, and it is widely used in bridges, high-rise buildings, and special structures. During the processing of UHPC concrete, the mixed raw materials need to be distributed in specific quantities to different aggregate containers to meet the needs of subsequent molding or further processing. The material distributor is a key piece of equipment for achieving this.

[0003] The existing UHPC concrete distributor has some shortcomings in practical use:

[0004] First, the accuracy of material distribution control is low, making it difficult to precisely adjust the amount of material in each distribution channel according to demand, which easily leads to uneven material distribution.

[0005] Secondly, traditional feeders have a low degree of automation, rely heavily on manual operation, and are difficult to link with the production line. In addition, materials are prone to overflow from the feeder chute during the feeding process, resulting in raw material waste and pollution of the production environment. Utility Model Content

[0006] In view of the shortcomings of the prior art, this utility model provides a material distributor for UHPC concrete processing, which overcomes the shortcomings of the prior art and effectively solves the problems of low material distribution control accuracy and low degree of automation.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A material distributor for UHPC concrete processing includes a base plate, a top plate on top of the base plate, and a storage tank at the center of the outer wall of the top of the top plate. Material distribution channels are welded around the bottom outer wall of the storage tank. A material distribution cylinder is fixedly connected to the bottom outer wall of the top plate at the bottom of the material distribution channels by screws. A solenoid valve is fixedly connected to the bottom outer wall of the material distribution cylinder by a flange. A discharge pipe is fixedly connected to the bottom outer wall of the solenoid valve by a flange. A collection cylinder is placed at the bottom of the discharge pipe on the top outer wall of the base plate.

[0009] Preferably, a fixing plate is welded to all four sides of the outer wall of the storage tank, and a screw rod is screwed onto the inner wall of the fixing plate, and a baffle plate is rotatably connected to the outer wall of the screw rod.

[0010] Preferably, the baffle plate is slidably connected to the inner wall of the material distribution channel.

[0011] Preferably, an array of uprights are welded between the base plate and the top plate, and a PLC controller is fixedly connected to the outer wall of one of the uprights by screws. The PLC controller is connected to the solenoid valve via a signal line.

[0012] Preferably, an overflow pipe is installed through one side of the outer wall of the storage tank, and a recovery cylinder is provided on the bottom outer wall of the overflow pipe.

[0013] Preferably, the top outer wall of the base plate is provided with positioning rings that are evenly distributed, and the collecting cylinder is located inside the positioning rings.

[0014] Preferably, a support frame is welded to the outer wall of the storage tank, and the support frame is fixedly connected to the top outer wall of the top plate by screws.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The UHPC concrete processing distributor designed in this paper uses a fixed plate, a screw rod, and a baffle plate installed on the outer wall of the storage tank. The baffle plate is slidably connected in the distribution channel. Rotating the screw rod can adjust the position of the baffle plate in the distribution channel, thereby controlling the opening size of the distribution channel and realizing precise adjustment of the distribution amount of each channel.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-4 Example 1: A material distributor for UHPC concrete processing includes a base plate 1, a top plate 2 on the top of the base plate 1, and a storage tank 3 at the center of the outer wall of the top of the top plate 2. Material distribution channels 4 are welded around the bottom outer wall of the storage tank 3. A material distribution cylinder 5 is fixedly connected to the bottom outer wall of the top plate 2 at the bottom of the material distribution channels 4 by screws. A solenoid valve 6 is fixedly connected to the bottom outer wall of the material distribution cylinder 5 by a flange. A discharge pipe 7 is fixedly connected to the bottom outer wall of the solenoid valve 6 by a flange. A collection cylinder 8 is placed at the bottom of the discharge pipe 7 on the top outer wall of the base plate 1. Positioning rings 16 are evenly distributed on the top outer wall of the base plate 1, and the collection cylinder 8 is located inside the positioning rings 16.

[0025] The positioning ring 16 on the top of the base plate 1 is used to fix the collecting cylinder 8, ensuring that the collecting cylinder 8 is directly opposite the bottom of the discharge pipe 7 to prevent material spillage during receiving. The top plate 2 is connected to the base plate 1 by the uprights 12 to form a stable frame structure. The storage tank 3 is fixed to the top center of the top plate 2 by the support frame 17. The material distribution slides 4 at the bottom of the storage tank 3 are radially distributed, which can guide the material to different distributing cylinders 5. The distributing cylinders 5, the solenoid valve 6 and the discharge pipe 7 are connected in sequence to form a complete material distribution channel. The solenoid valve 6 is responsible for controlling the opening and closing of this channel.

[0026] In this embodiment, a fixing plate 9, a lead screw 10, and a baffle plate 11 are provided on the outer wall of the storage tank 3. The baffle plate 11 is slidably connected in the material distribution slide 4. Rotating the lead screw 10 can adjust the position of the baffle plate 11 in the material distribution slide 4, thereby controlling the opening size of the material distribution slide 4 and realizing precise adjustment of the material distribution amount in each channel. At the same time, the PLC controller 13 is linked with the solenoid valve 6 to precisely control the opening and closing time of the feeding pipe 7, further ensuring the accuracy of the material distribution amount and meeting the needs of different production scenarios.

[0027] In the second embodiment, a fixing plate 9 is welded to all four sides of the outer wall of the storage tank 3, and a screw rod 10 is screwed onto the inner wall of the fixing plate 9. A baffle plate 11 is rotatably connected to the outer wall of the screw rod 10, and the baffle plate 11 is slidably connected to the inner wall of the material distribution slide 4.

[0028] The fixing plate 9 on the outer wall of the storage tank 3 provides support for the lead screw 10. The lead screw 10 is screwed to the fixing plate 9. When the lead screw 10 is rotated, the baffle plate 11 at its end can slide within the distribution slide 4, thereby changing the flow cross-sectional area of ​​the distribution slide 4. When it is necessary to increase the distribution volume, the lead screw 10 is rotated outward, and the baffle plate 11 moves to the outside of the distribution slide 4, increasing the opening; conversely, the opening decreases, realizing flexible adjustment of the distribution volume. The sliding fit between the baffle plate 11 and the distribution slide 4 ensures the smoothness and sealing of the adjustment process, preventing material leakage from the gaps.

[0029] In this embodiment, the overflow pipe 14 on one side of the storage tank 3 can guide excess material into the recycling cylinder 15 to prevent material overflow and environmental pollution. In addition, the positioning ring 16 on the bottom plate 1 can fix the position of the collecting cylinder 8 to prevent it from shifting when receiving material and reduce material spillage.

[0030] An array of uprights 12 are welded between the base plate 1 and the top plate 2, and a PLC controller 13 is fixedly connected to the outer wall of one of the uprights 12 by screws. The PLC controller 13 is connected to the solenoid valve 6 by a signal line.

[0031] The upright pole 12 not only supports the top plate 2 and the bottom plate 1, but also provides an installation position for the PLC controller 13. The PLC controller 13 is connected to the solenoid valve 6 through a signal line, and the opening and closing time of each solenoid valve 6 can be preset to realize automated material distribution.

[0032] An overflow pipe 14 is installed through one side of the outer wall of the storage tank 3, and a recovery cylinder 15 is provided on the bottom outer wall of the overflow pipe 14.

[0033] The overflow pipe 14 is installed on the side of the storage tank 3. When there is too much material in the storage tank 3, the excess material flows into the recycling cylinder 15 through the overflow pipe 14, which facilitates recycling and reuse and reduces raw material waste.

[0034] A support frame 17 is welded to the outer wall of the storage tank 3, and the support frame 17 is fixedly connected to the top outer wall of the top plate 2 by screws.

[0035] The support frame 17 enhances the load-bearing capacity of the storage tank 3 and prevents it from tilting when filled with materials.

[0036] Working principle: Before the device starts working, the collecting cylinder 8 is placed into the positioning ring 16 of the base plate 1 to ensure that it is aligned with the feeding pipe 7. The opening time of each solenoid valve 6 is preset by the PLC controller 13. According to the material distribution requirements, the screw 10 is rotated to adjust the position of the baffle plate 11 in the material distribution slide 4 and determine the material distribution amount of each channel.

[0037] UHPC concrete material is injected into the storage tank 3. Under the action of gravity, the material flows into the distribution chute 4 and enters the distribution cylinder 5 after being adjusted by the baffle plate 11. The PLC controller 13 controls the corresponding solenoid valve 6 to open according to the preset program, and the material falls into the corresponding collection cylinder 8 through the discharge pipe 7.

[0038] When there is too much material in the storage tank 3, the excess material flows into the recovery cylinder 15 through the overflow pipe 14. After the material distribution is completed, the PLC controller 13 closes the solenoid valve 6, and the collection cylinder 8 can be removed.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
