Description

Technical Field

[0001] This utility model relates to the technical field of refractory material weighing silo devices, and in particular to an automatic weighing silo for refractory material production. Background Technology

[0002] Refractory materials are inorganic non-metallic materials with a refractoriness of not less than 1580℃, good resistance to thermal shock and chemical corrosion, low thermal conductivity, and low coefficient of expansion. They are mainly manufactured from natural minerals such as bauxite, silica, magnesite, and dolomite through processing.

[0003] The production of refractory materials generally requires the initial crushing of raw materials, followed by various processing steps to create products of specific sizes and shapes. During this process, an automatic weighing silo is needed to weigh the materials used in refractory production, facilitating the proportioning of raw materials. However, when the powder is weighed and discharged from the silo, there is a risk of powder sticking and clogging the outlet, severely impacting production efficiency. Furthermore, existing weighing silos cannot quantitatively discharge powder. Therefore, this application specifically proposes an automatic weighing silo for refractory material production to address these issues. Utility Model Content

[0004] To address the above situation and overcome the shortcomings of existing technologies, this utility model provides an automatic weighing hopper for refractory material production. The technical solution it provides includes a frame, characterized in that a weighing sensor is fixedly connected to the frame, the weighing sensor is fixedly connected to a hopper, a conical guide portion is coaxially fixedly connected to the bottom of the hopper, a discharge pipe is coaxially fixedly connected to the lower end of the guide portion, a longitudinally arranged combing pipe is integrally connected to the discharge pipe, and a combing roller is coaxially rotatably connected to the combing pipe. The combing roller has multiple combing grooves evenly distributed around its axis. Each sidewall edge of the combing groove is provided with several evenly distributed combing teeth. The front end of the combing tube is fixedly connected to a first stepper motor for driving the combing roller. The sidewall of the discharge tube has a through mounting groove that runs from left to right. A transverse baffle is slidably connected to the mounting groove. Two crossbars are fixedly connected to the right end of the discharge tube. The two crossbars are fixedly connected to a mounting plate. A driving device for driving the transverse baffle is provided between the mounting plate and the sidewall of the discharge tube.

[0005] Preferably, the driving device includes a lead screw located between two crossbars, with its left and right ends rotatably connected to the side wall of the discharge pipe and the mounting plate, respectively. The lead screw is threaded with an inner connecting rod, and each of the crossbars is slidably connected with an outer connecting rod. Both the inner and outer connecting rods are fixedly connected to a transverse baffle. The mounting plate is fixedly connected with a second stepper motor for driving the lead screw.

[0006] Preferably, the frame consists of two support legs symmetrically arranged about the hopper, and there are two weighing sensors, each corresponding to and fixedly connected to one of the support legs.

[0007] The beneficial effects of this utility model are: In use, the powder is added to the hopper and weighed by a weighing sensor. When the powder needs to be discharged after weighing, the drive device is activated to move the transverse baffle to the right, thus disengaging it from the discharge pipe. At this time, the powder can be discharged downward through the discharge pipe. Furthermore, to prevent the powder from sticking and clogging the discharge pipe, a combing roller is installed at the discharge pipe. When discharging the powder, the first stepper motor drives the combing roller to rotate. The rotation of the combing roller not only discharges the powder quantitatively through the sifting trough, but also scrapes the powder with the sifting teeth, thereby breaking down any sticky powder and preventing the powder from clogging the discharge pipe, ensuring normal discharge. This application has a simple structure, is easy to use, and is highly practical. Attached Figure Description

[0015] The following is in conjunction with the appendix Figure 1-6 The specific embodiments of this utility model will be described in further detail.

[0016] In the first embodiment, the technical solution is as follows: When using this application, powder is added to the hopper 3 and then weighed by the weighing sensor 2. When the powder needs to be discharged after weighing, the drive device 15 is started to drive the transverse baffle 12 to move to the right and thus disengage from the discharge pipe 5. At this time, the powder can be discharged downward through the discharge pipe 5. Furthermore, in order to avoid the powder sticking and blocking the discharge pipe 5, a combing roller 7 is provided at the discharge pipe 5. When discharging the powder, the first stepper motor 10 drives the combing roller 7 to rotate. The rotation of the combing roller 7 can not only discharge the powder quantitatively through the sifting groove, but also scrape the powder through the sifting teeth, thereby breaking the sticky powder and preventing the sticky powder from blocking the discharge pipe 5, thus ensuring normal discharge.

[0017] In Example 2, based on Example 1, specifically, in this application, a weighing sensor 2 fixedly connected to the hopper 3 is installed on the frame 1, i.e., the support leg 20, thereby enabling automatic weighing of the powder in the hopper 3. Under normal circumstances, the transverse baffle 12 is as shown in the attached drawings. Figure 2 The material is fully inserted into the mounting slot 11, thereby completely blocking the discharge pipe 5 and preventing material from being discharged through the discharge pipe 5, which would affect the weighing of the material. The guide part 4 facilitates the collection and discharge of powder into the discharge pipe 5.

[0018] When powder needs to be discharged, the second stepper motor 19 on the mounting plate 14 is started to rotate forward to the set stroke. The forward stroke of the second stepper motor 19 will drive the lead screw 16 to rotate forward to the corresponding stroke. The forward rotation of the lead screw 16 will drive the transverse baffle 12 through the inner connecting rod 17 that is threaded with it. The transverse baffle 12 is in sliding engagement with the crossbar 13 through the outer connecting rod 18. Therefore, the forward rotation of the lead screw 16 will drive the transverse baffle 12 to slide to the right along the crossbar 13. As a result, the transverse baffle 12 will gradually disengage from the blockage of the discharge pipe 5, and the powder can then flow downward through the discharge pipe 5. Furthermore, to ensure quantitative and smooth material discharge, and more importantly, to prevent material adhesion and blockage of the discharge pipe 5, a combing roller 7 is installed. Multiple combing grooves 8 and several combing teeth 9 are evenly distributed around the combing roller 7. When the first stepper motor 10 is started, it drives the combing roller 7 to rotate. During rotation, powder sequentially fills each combing groove 8, and discharges the powder when each combing groove 8 faces downwards. This achieves quantitative powder discharge, facilitating the quantitative addition of powder to external molding devices and improving production efficiency. Additionally, during the rotation of the combing roller 7, the combing teeth continuously scrape the powder, breaking down any adhered material and preventing blockage of the discharge pipe 5, ensuring normal material discharge.

[0019] In Example 3, based on Example 2, the second motor on the mounting plate 14 is started to reverse the set stroke. The second stepper motor 19 reverses the set stroke, which will drive the lead screw 16 to reverse the corresponding stroke, thereby driving the transverse baffle 12 to move to the left by the corresponding stroke and reset, so that the transverse baffle 12 can block the discharge pipe 5 again.
