[0020] 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.
[0021] like Figures 1-3 The dustproof filling device for powder products shown includes a conveyor belt 1 and a hopper 2. A barrel-shaped container 11 is placed on the surface of the conveyor belt 1. The barrel-shaped container 11 is used to package powdered polycarboxylate superplasticizer. The top of the barrel-shaped container 11 is open. The barrel-shaped container 11 is carried and transferred by the conveyor belt 1. The hopper 2 is installed horizontally above the conveyor belt 1. The hopper 2 stores the powdered polycarboxylate superplasticizer to be packaged. The original hopper 2 only had a simple pipeline with a control valve connected to its bottom. When the control valve was opened, the pipeline was open to output the powdered polycarboxylate superplasticizer for filling operations. During filling, a serious dust problem was found. This invention improves the equipment to address the dust problem. First, this invention installs a telescopic discharge pipe 3 at the bottom of the hopper 2. The telescopic discharge... Fitting 3 is connected below the existing pipeline. The telescopic discharge fitting 3 has a telescopic extension function. When using the telescopic discharge fitting 3 for filling, the outlet of the fitting can be closer to the barrel-shaped container 11, thus greatly reducing the drop difference between the outlet and the barrel-shaped container 11 and significantly reducing dust emission. Since there is still some dust, this utility model also connects a dustproof filling mechanism 4 below the telescopic discharge fitting 3. The dustproof filling mechanism 4 includes a filling pipe 41 and a dustproof cover 42. The filling pipe 41 is flanged and connected below the telescopic discharge fitting 3. The powdered polycarboxylate superplasticizer to be filled is finally output from the filling pipe 41. After the barrel-shaped container 11 flows with the conveyor belt 1, it can stay below the filling pipe 41 to facilitate the filling operation. To ensure that the barrel-shaped container 11 stops accurately, such as Figure 1As shown, the support feet of the bin 2 are provided with a position detection element 21, which is installed corresponding to the position of the filling pipe 41. The position detection element 21 is an infrared sensor, and an infrared identification paper is attached to the outer wall of the barrel-shaped container 11. After the position detection element 21 detects the infrared identification paper, the barrel-shaped container 11 can be accurately stopped at a position below the filling pipe 41 to complete the filling. After the barrel-shaped container 11 is stopped, the telescopic discharge pipe 3 drives the filling pipe 41 to descend and insert into the barrel-shaped container 11 to complete the filling. The dust cover 42 is sleeved on the outer side of the filling pipe 41 and descends with the filling pipe 41 to exactly close the top opening of the barrel-shaped container 11 to ensure that the dust does not escape during filling. By further installing the dustproof filling mechanism 4, the dust problem during filling can be completely solved. The dustproof filling mechanism 4 is connected with the telescopic discharge pipe 3 by flanges, which has the advantages of convenient installation and low transformation cost.
[0022] As shown in the drawings, Figure 1 The telescopic discharge pipe 3 comprises a discharge pipe 31 and a lifting push cylinder 32. The lifting push cylinder 32 is vertically installed downward. The discharge pipe 31 comprises a telescopic section 311 and a butt joint section 312. One end of the telescopic section 311 is connected to the bottom of the bin 2, and the other end of the telescopic section 311 is connected to the butt joint section 312. The telescopic section 311 is a flexible pipe and can change in length. The butt joint section 312 is a rigid pipe and is responsible for flange connection with the filling pipe 41. The piston rod end of the lifting push cylinder 32 is fixedly connected with the butt joint section 312. When the piston rod of the lifting push cylinder 32 extends downward, the telescopic section 311 changes in length, and the butt joint section 312 and the filling pipe 41 move downward to meet the needs of filling.
[0023] Although the dust cover 42 installed on the outer side of the filling pipe 41 can solve the problem of dust flying outward, the dust flying upward will adhere to the inner cover surface of the dust cover 42, which will cause deviation of the filling amount. Moreover, since the inner cover surface of the dust cover 42 has dust, the dust adhered to the inner cover surface of the dust cover 42 will fall during the switching of the next barrel-shaped container 11, which will cause pollution of the belt surface of the conveying belt 1. In view of the above situation, the installation mode of the dust cover 42 is improved, as shown in the drawings, Figure 3As shown, the utility model discloses a rotating seat 43 is rotationally installed on the outer wall of filling pipe 41, and dust cover 42 is sleeved on the outside of filling pipe 41 and is fixedly connected with rotating seat 43, the utility model discloses dust cover 42 can rotate relative to filling pipe 41 through rotating seat 43, and the utility model discloses still be fixedly connected with clear cover plate 44 on the outer wall of filling pipe 41, and clear cover plate 44 is vertically connected, and the inner cover surface of dust cover 42 is kept in contact with the upper end of clear cover plate 44, the inner cover surface of dust cover 42 can be cleaned through clear cover plate 44, so that the dust adhered on the inner cover surface of dust cover 42 falls, and the cleaning operation of the inner cover surface of dust cover 42 is carried out after filling is completed, dust cover 42 rotates more than two rounds, and filling is completed only after dust cover 42 is cleaned, and conveyor belt 1 is started again to replace new barrel-shaped container 11.
[0024] As Figure 3 Shown, filling pipe 41 outside installs clear cover power assembly 45, and clear cover power assembly 45 is transmissionally connected with rotating seat 43, and the rotation of rotating seat 43 is driven through clear cover power assembly 45, to realize the rotation of dust cover 42, and clear cover power assembly 45 includes motor base 451 and motor 452, and motor base 451 is installed on the outer wall of filling pipe 41, and motor 452 is fixedly installed on motor base 451, and motor 452 is output-connected with driving gear 453, and rotating seat 43 outer wall is connected with a circle of transmission gear ring 431, and driving gear 453 is engaged with transmission gear ring 431, since dust cover 42 rotation demand is not big, therefore, motor 452 can adopt micro motor, and after motor 452 is started, the rotation of rotating seat 43 and dust cover 42 is driven through the engagement relationship of driving gear 453 and transmission gear ring 431.
[0025] As Figure 3 Shown, dust cover 42 needs to be installed from the side of the flange plate of filling pipe 41, and therefore the inner hole diameter of dust cover 42 is greater than the diameter of the flange plate of filling pipe 41, so as to facilitate installation, and after dust cover 42 is installed and connected with rotating seat 43, clear cover power assembly 45 is installed.
[0026] The above only is the preferred implementation of the utility model, the protection scope of the utility model is not only limited to the above-mentioned embodiment, and all technical solutions under the idea of the utility model belong to the protection scope of the utility model for the person of ordinary skill in the art. It should be pointed out that for the person of ordinary skill in the art, a number of improvements and refinements without departing from the principle of the utility model, and these improvements and refinements should also be considered as the protection scope of the utility model.
