TECHNICAL FIELD

[0001] The utility model relates to the technical field of metal new material mixing equipment, concretely is integrated formula weighing equipment of manganese additive. BACKGROUND

[0002] Manganese additive refers to a kind of additive for adding manganese-containing substance in industrial production to improve product performance, improve production efficiency and other purposes, and is widely used in steel, non-ferrous metal, chemical industry and other industries.

[0003] Manganese additive needs to mix manganese raw material and various additives when preparing, and the dosage of manganese raw material and various additives needs to be measured when mixing, otherwise the performance will be affected due to improper proportioning of additives.In actual production, the raw material is usually accurately weighed by using a silo type weighing device to realize accurate proportioning of various additives before mixing. For example, the prior art "a multi-component weighing type mixing device" (publication number: CN214863306U) sets multiple silos above the weighing hopper, adjusts the opening degree of the discharge port of the corresponding silo through the feeding device to realize accurate proportioning of the materials in each silo. However, the prior art still has the following technical problems:

UTILITY MODEL CONTENTS

[0005] The utility model provides integrated formula weighing equipment of manganese additive, can solve the problem that the weighing equipment in the prior art is easy to cause impurities to enter the weighing hopper and pollute the raw material, affecting product quality.

[0008] Advantages:

[0009] 1. The filter strip cloth, rope impurities, avoid raw material pollution, ensure product quality. The steel strip of the filter screen is distributed at equal intervals to form a certain size of filter gap, which can prevent small volume impurities from passing through, especially prevent some long cloth strips, pocket lines and other impurities from falling into the weighing hopper, thereby avoiding the pollution of impurities to the raw materials, the manganese additive entering the silo is relatively pure, reducing the influence of impurities on the purity of raw materials, and ensuring the product quality.

[0010] 2. Reasonable structure design, avoid material leakage: the bottom net of the filter screen is composed of a rectangular steel frame and a plurality of steel strips fixed at equal intervals on the steel frame. This structure has certain strength and stability, can withstand the impact and weight of large volume solid impurities, is not easy to deform or damage, and ensures the durability of the filtering effect. At the same time, the hooks are hung on the edge of the feeding port, so that the bottom net sinks below the mouth of the feeding port. This installation method not only facilitates the disassembly and replacement of the filter screen, but also ensures that large volume impurities do not protrude above the horizontal plane of the feeding port when feeding, so that the material is scattered and leaked outside the feeding port due to the impact of large volume impurities, thereby avoiding the waste of materials.

[0011] Further, the weighing sensor is arranged on the mounting bracket of the weighing hopper.

[0012] Beneficial effect: Since different additives are placed in each silo, the weight of the raw materials in the weighing hopper can be measured in real time through the weighing sensor, so as to detect the amount of each additive added, ensure that the product after production meets the requirements of the production formula, and thus ensure the stability and consistency of product quality.

[0013] Further, the discharge port of the silo is provided with a swing valve.

[0014] Beneficial effect: According to the production demand, the discharge speed and amount of each silo can be adjusted by controlling the valve, so as to ensure that the material is put into the weighing hopper according to the set amount, improve the accuracy of material proportioning, and ensure product quality.

[0015] Further, the bottom net is provided with multiple layers, and the arrangement directions of the steel strips between the layers are perpendicular to each other.

[0016] Beneficial effect: The steel strips are arranged in different directions to form an interwoven structure in space, which can filter the material more finely. When the material passes through the bottom net, the grid formed by the steel strips in different directions can intercept impurities of different shapes and sizes, improve the success rate of interception, and more comprehensively filter the impurities in the material, improve the purity of manganese raw materials entering the weighing hopper, and facilitate the smooth progress of the subsequent production process, reducing the influence of impurities on product quality.

[0017] Further, support blocks are further fixed on both sides of the feeding port.

[0018] Beneficial effects: since the manganese raw material is in the form of bag when it is fed, and the supporting blocks can be used to support the manganese raw material bag when feeding, the manganese raw material bag is erected between the supporting blocks, so that the operator can cut the bag and make the manganese raw material fall into the feeding port below, and the filtering function is realized.

[0019] Further, the outer wall of the weighing hopper is fixed with a vibration motor.

[0020] Beneficial effects: since the vibration motor can drive the weighing hopper to vibrate, the mixing of the material in the weighing hopper is promoted, the stratification of the material in the weighing hopper is avoided, the uniformity of the material mixing is improved, and some materials that are condensed into groups are also scattered, and the mixing effect is improved.

[0025] The following will be further described in detail through specific embodiments:

[0026] The marks in the drawings of the specification include: support frame 1, weighing hopper 2, swing valve 3, material bin 4, feeding port 5, supporting block 6, bottom screen 701, steel bar 702, hook 703, steel frame 704.

[0027] Embodiment one

[0028] As Figures 1 to 4 shown, the integrated weighing device for manganese additive includes a support frame 1, a weighing hopper 2 fixed on the support frame 1, and a plurality of material bins 4 located above the weighing hopper 2 and fixed on the support frame 1.

[0029] As Figure 2 and Figure 3As shown, the silo 4 is provided with a filtering unit above, the filtering unit comprising a feeding opening 5 opened at the top of the silo 4 and a filtering screen erected on the feeding opening 5, the filtering screen comprising a bottom screen 701 and a hook 703 fixed around the bottom screen 701, the bottom screen 701 comprising a rectangular steel frame 704 and a plurality of steel bars 702 fixed at equal intervals on the holes of the steel frame 704, the hook 703 being hung on the edge of the feeding opening 5, the edge of the feeding opening 5 being provided with a recessed clamping groove so as to facilitate the clamping of the hook 703 in the clamping groove to realize the fixation of the entire filtering screen, and meanwhile the bottom screen 701 sinks downward below the mouth of the feeding opening 5. The feeding opening 5 is further provided with support blocks 6 on both sides, since the manganese raw material is in the form of a bag when it is delivered, and the support blocks 6 can be used to support the manganese raw material bag during feeding, and the manganese raw material bag is erected between the support blocks 6 so as to facilitate the operator to cut the bag and let the manganese raw material fall into the feeding opening 5 below to realize the filtering function.

[0030] The discharge opening of the silo 4 is provided with a swing valve 3, which can adjust the discharging speed and discharging amount in each silo 4 according to the production requirements by controlling the opening degree of the valve, so as to ensure that the material is put into the weighing hopper 2 according to the set amount, improve the accuracy of material proportioning, and ensure the product quality.

[0031] The weighing sensor is further provided on the mounting bracket of the weighing hopper 2. Since different additives are contained in each silo 4, the weight of the raw material in the weighing hopper 2 can be measured in real time by the weighing sensor, so as to detect the adding amount of each additive each time, ensure that the product after production meets the requirements of the production formula, and thus ensure the stability and consistency of the product quality.

[0032] The use method of the present scheme is as follows:

[0033] The bagged manganese raw material additives are hoisted to the upper side of the material bin 4 by the crane, and are erected between the supporting blocks 6. The bag containing the manganese raw material additives is cut by a tool to make the manganese raw material additives fall down along the broken opening to the filter screen. The filter screen can filter the manganese additives entering the material bin 4. The impurities such as nylon bag broken pieces, larger plastic pieces and the like are intercepted by the filter screen and cannot enter the material bin 4. The steel bars 702 of the filter screen are distributed at equal intervals to form a certain size of filtering gap, which can prevent some long cloth strips, bag lines and the like from falling into the weighing hopper 2, thereby avoiding the pollution of the impurities to the raw materials. The manganese additives entering the material bin 4 are relatively pure, the influence of the impurities on the purity of the raw materials is reduced, and the product quality is ensured. The bottom net 701 of the filter screen is composed of a rectangular steel frame 704 and a plurality of steel bars 702 fixed at equal intervals on the steel frame 704. This structure has certain strength and stability, can withstand the impact and weight of the solid impurities of large volume, is not easy to deform or damage, and ensures the persistence of the filtering effect. At the same time, the hooks 703 are hung at the edge of the feeding opening 5 to make the bottom net 701 sink below the mouth of the feeding opening 5. This installation method is convenient for dismounting and replacing the filter screen, and can ensure that the large-size impurities do not protrude above the horizontal plane of the feeding opening 5 when the materials are fed, so that the materials are not scattered and leaked outside the feeding opening 5 due to being pushed by the large-size impurities, thereby avoiding the waste of materials.

[0034] When the material is proportioned, the opening degree of the swing valve 3 below each material bin 4 can be adjusted to control the discharging sequence of each material bin 4. For example, the left material bin 4 is first opened in Figure 1 , the materials fall into the weighing hopper 2, and the swing valve 3 of the left material bin 4 is closed when the display weight of the weighing sensor reaches the predetermined proportioning. The swing valve of the middle material bin 4 is opened to feed the materials. The right material bin 4 is fed in the same way. Through this cross discharging method, the materials in each material bin 4 are automatically mixed when falling into the weighing hopper 4, the stirring equipment is omitted, and the cost is reduced. In addition, the three material bins 4 can be simultaneously fed. The three material bins 4 are simultaneously opened. Since the materials falling from the two side material bins 4 will first contact the side wall of the weighing hopper 2, the materials falling from the middle material bin 4 will fall faster. Therefore, the opening degree of the swing valve 3 of the middle material bin 4 can be adjusted to be small, and the opening degree of the swing valve 3 of the two side material bins 4 can be adjusted to be large, so that the discharging speeds of the three material bins 4 are more uniform. When the materials in the three material bins 4 gradually accumulate at the bottom of the weighing hopper 2, the stratification phenomenon is not easy to occur. The materials are discharged from the channel below the weighing hopper 2, and are automatically mixed in the channel during the discharging process. The subsequent materials can be directly bagged.

[0035] Example Two

[0036] As Figure 4As shown, the difference between the embodiment and embodiment one is that the bottom net 701 is provided with multiple layers, and the arrangement directions of the steel bars 702 between the layers of the bottom net 701 are perpendicular to each other. The steel bars 702 are arranged in different directions, and the spatially interwoven structure is formed, which can filter the material more finely. When the material passes through the bottom net 701, the grids formed by the steel bars 702 in different directions can intercept impurities of different shapes and sizes, improve the success rate of interception, can more comprehensively filter the impurities in the material, improve the purity of the manganese raw material entering the weighing bin 4, and is conducive to the smooth progress of the subsequent production process, and reduces the influence of impurities on the product quality.

[0037] Embodiment three

[0038] The difference between the embodiment and embodiment one is that the weighing hopper 2 is fixed with a vibration motor on the outer wall. After the weighing and proportioning are completed, the vibration motor can be started, and the vibration motor can drive the weighing hopper 2 to vibrate, promote the mixing of the material in the weighing hopper 2, avoid the stratification phenomenon of the material in the weighing hopper 2, improve the uniformity of the material mixing, and also can shake some materials that are condensed into groups, and improve the mixing effect.
