Description

Technical Field

[0001] This utility model relates to the field of weighing equipment technology, specifically to a weighing device for mixing granulated admixtures. Background Technology

[0002] The composite admixture is formulated by optimizing the composition of ultrafine silica powder, highly active mineral powder and a variety of high-performance additives. It has a high activity index, and the addition of this reinforced mineral admixture can significantly improve the mechanical properties and durability of track slab concrete.

[0003] Existing technologies, such as CN215463964U, describe an automatic compounding device. First, two different raw materials are poured into a storage bin. Then, with the cooperation of a baffle plate and a gravity sensor, the raw materials entering the storage bin are weighed. When the specified weight is reached, a cylinder is activated. The cylinder's output shaft moves the baffle plate out of the feed pipe. The raw materials then fall through an elastic tube onto a screen in a sieve box. A vibration motor is then activated, and its output shaft drives the sieve box to vibrate. The raw materials are then screened and mixed through the sieve. The screened raw materials then enter a mixing box for further mixing.

[0004] In the existing technology, during the batching process, the admixtures to be mixed are weighed separately, and then the weighed admixtures are put together for screening. As a result, since different types of admixtures contain different lumpy impurities, screening may disrupt the proportion of different components of the admixtures. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] The existing admixture mixing device is installed below the weighing hopper. In use, the material is weighed first and then screened, which results in the final amount of admixture being less than the actual required amount.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention provides the following technical solution: a weighing device for mixing granulated admixtures, including a weighing hopper, a feeding pipe for connecting to a mixing box at the lower end of the weighing hopper, a valve mechanism installed on the feeding pipe, a screening mechanism installed at the upper end of the weighing hopper, and a collection frame mechanism for receiving screened impurities installed on the upper side of the weighing hopper.

[0009] The screening mechanism includes a screening screen, which is inclinedly arranged at the top of the weighing hopper;

[0010] The collection frame mechanism includes a collection frame installed on the upper side of the weighing hopper, the top side of the collection frame being close to and flush with the lower end of the screening screen;

[0011] The lower end of the screening mesh is rotatably connected to the weighing hopper, and a support block is fixed to the inner wall of the weighing hopper. The other end of the screening mesh overlaps the surface of the support block.

[0012] 3. Beneficial effects

[0013] Compared with the prior art, the beneficial effects of this utility model are: by setting the screening mechanism at the top of the weighing hopper, the process of screening and removing impurities from the admixture before weighing is realized, avoiding the problems of insufficient quantity of admixture and imbalance of proportion caused by weighing before screening; at the same time, the rotatable design of the screening screen facilitates the cleaning of residual materials, and the pull-out collection frame facilitates the handling of impurities. The overall structure improves the weighing accuracy and operation convenience. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figs. 1-3 This utility model provides the following technical solution: a weighing device for mixing granulated admixtures, including a weighing hopper 2, with a discharge pipe 5 at the lower end of the weighing hopper 2 for connecting to a mixing box 4. The mixing box 4 is used to mix the proportioned admixtures. The discharge pipe 5 is equipped with a valve mechanism 3, which is connected to the mixing box 4 and is used to transport the proportioned raw materials in the weighing hopper 2 into the mixing box 4. The above is the existing structure. For details, please refer to CN215463964U, an automatic compound admixture preparation device, which will not be described in detail here.

[0019] It is understandable that the existing admixture mixing device is installed below the weighing hopper 2. In use, the material is weighed first and then screened. This results in the final amount of admixture being lower than the actual required amount. Therefore, the main innovation of this utility model is as follows:

[0020] The weighing hopper 2 is equipped with a screening mechanism 1 at its upper end, and a collection frame mechanism for receiving screened impurities is installed on the upper side of the weighing hopper 2.

[0021] The screening mechanism 1 includes a screening screen 12, which is inclinedly arranged on the top of the weighing hopper 1. The collection frame mechanism includes a collection frame 10 installed on the upper side of the weighing hopper 2. The top of the collection frame 10 is open, and the top side of the collection frame 10 is close to and flush with the lower end of the screening screen 12. In use, the admixture is poured onto the higher end of the screening screen 12. Under the action of weight, the admixture rolls towards the lower end of the screening screen 12. Small particles that meet the usage requirements pass through the mesh of the screening screen 12 and enter the interior of the weighing hopper 12 for weighing, while unsuitable materials roll down to the lower end of the screening screen 12 and are collected by the collection frame 10.

[0022] The lower end of the screening screen 12 is rotatably connected to the weighing hopper 1, and a support block 11 is fixed to the inner wall of the weighing hopper 2. The other end of the screening screen 12 overlaps the surface of the support block 11. With the above structure, the screening screen 12 can rotate at the upper end of the weighing hopper 2. In this way, after weighing, the screening screen 12 can be rotated to pour the remaining material on the surface of the screening screen 12 into the collection frame 10.

[0023] The valve mechanism 3 includes a valve plate 32 movably disposed on the side of the feed pipe 5. An electronic scale 31 is embedded in the surface of the valve plate 32. A telescopic cylinder 33 is fixed on the outer side of the feed pipe 5. The telescopic end of the telescopic cylinder 33 is fixedly connected to one end of the valve plate 32. The valve mechanism 3 can also directly adopt the existing structure in the automatic compounding device of CN215463964U. In use, the electronic scale 31 is used to weigh the raw materials. After weighing, the telescopic cylinder 33 is shortened to drive the valve plate 32 to move, so that the raw materials enter the mixing box 4 and wait for the next mixing step.

[0024] Specifically, a rotating shaft 11 is fixed to the lower end of the screening screen 12, and the rotating shaft 11 is rotatably connected to the weighing hopper 2. A handle 13 is fixed to the higher end of the screening screen 12.

[0025] The upper side of the weighing hopper 2 is provided with a slot structure 7, and the upper sides of the collection frame 10 are provided with plug-in blocks 8 corresponding to the slot structure 7. The collection frame 10 is fixed with a pull handle 9. With the above structure, the collection frame 10 can be slidably inserted into the side of the weighing hopper 2 like a drawer, which is convenient for installation. After collection is completed, the collection frame 10 can be slid out to take out the filtered raw material.

[0026] The present invention aims to provide a weighing device for mixing granulated admixtures. By integrating the screening mechanism 1 at the upper end of the weighing hopper 2 and matching it with a collection frame mechanism for receiving screened impurities, the invention solves the problem that the existing admixture mixing device, which "weighs first and then screens," results in a final admixture quantity lower than the actual requirement and may damage the proportion of different admixture components.

[0027] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
