Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, and in particular to a parallel feeding device. Background Technology

[0002] Foaming is a common problem in industrial production, and defoamers are additives that reduce surface tension, inhibit foam generation, or eliminate existing foam. Currently, defoamers are widely used in petrochemical, pulp and paper, textile printing and dyeing, food processing, pharmaceutical fermentation, coatings and inks, water treatment and other fields. In order to speed up the feeding efficiency during production, parallel feeding devices are used. However, in actual production, due to the large amount of raw materials required, mixing is also necessary in the production equipment.

[0003] For example, Chinese patent application CN202321235333.3 discloses a parallel feeding device for preparing defoamer. Specifically, multiple storage tanks are connected by a connecting pipe (the connecting pipe is U-shaped when there are two storage tanks). A feeding pipe is connected below the connecting pipe, enabling parallel feeding for convenient processing. The feeding pipe contains a premixing mechanism, including a guide plate welded to the top of the feeding pipe. A rotating rod is rotatably mounted below the guide plate, horizontally positioned, and premixing blades are welded equidistantly to its circumference. Material entering the feeding pipe through the connecting pipe is guided by the guide plate and then flows onto the premixing blades of the rotating rod. Due to contact with the premixing blades at the lower end of the guide plate, a downward thrust is generated on the premixing blades, causing the rotating rod to rotate. This facilitates premixing of the internal material. However, this device has the following technical problems:

[0004] In the preparation of defoamers, multiple raw materials need to be mixed. However, due to the different proportions of the raw materials, when multiple raw materials are premixed using the above-mentioned existing technology, the raw materials with a smaller proportion will be consumed in advance, while the raw materials with a larger proportion will still have a lot left, resulting in insufficient mixing effect of the raw materials to be premixed later. Utility Model Content

[0005] To address the problem mentioned in the background art that it is difficult to fully premix raw materials with different amounts, this utility model provides the following technical solution:

[0006] A parallel feeding device includes a feeding device;

[0007] The feeding device includes multiple raw material cylinders for holding raw materials, and the feeding device includes a raw material mixing cylinder for preliminary mixing of the raw materials.

[0008] The lower end of the raw material cylinder is equipped with a first discharge pipe to facilitate the delivery of raw materials into the interior of the raw material primary mixing cylinder, and a valve is installed in the middle of the first discharge pipe to facilitate the control of the raw material descent rate.

[0009] The raw material primary mixing cylinder is equipped with a primary mixing component to facilitate the mixing of raw materials.

[0010] Furthermore, a support device for supporting the feeding device is installed at one end of the feeding device, and the support device includes a support frame.

[0011] Furthermore, a first motor for controlling the rotation of the feeding device is installed at the upper end of the support frame, a first rotating shaft is installed at the output end of the first motor, a first flange is installed at the lower end of the first rotating shaft, and multiple bolts are installed in the middle of the first flange.

[0012] Furthermore, a support plate for supporting multiple raw material cylinders is installed at the lower end of the raw material cylinder, a second rotating shaft is installed in the middle of the support plate, and a second flange for limiting the support plate with bolts is installed at the upper end of the second rotating shaft.

[0013] Furthermore, a feed pipe is installed at the upper end of the raw material cylinder, and a sealing cap for sealing the upper end of the feed pipe is installed at the upper end of the feed pipe. An observation window is provided in the middle of the raw material cylinder.

[0014] Furthermore, the raw material initial mixing cylinder includes a cylinder body, the upper end of which is machined with a plurality of mounting ports for limiting the first discharge pipe, and the lower end of the cylinder body is equipped with a second discharge pipe.

[0015] Furthermore, the primary mixing component includes a primary mixing disc, and the upper end of the primary mixing disc is machined with an arc-shaped surface for guiding the raw materials. The middle part of the feed pipe is provided with multiple discharge holes for the raw materials to fall. The middle part of the primary mixing disc is equipped with multiple V-shaped protrusions for stirring the raw materials.

[0016] Furthermore, a third rotating shaft is installed in the middle of the primary mixing disc, and a second motor is installed at the upper end of the third rotating shaft to cooperate with the third rotating shaft to control the rotation of the primary mixing disc.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] By setting valves, the first discharge pipe with more raw materials is able to continue mixing even when the raw materials are almost finished, while the first discharge pipe with less raw materials still has raw materials to mix. This ensures that the raw materials are mixed more thoroughly. When the various raw materials fall from the top of the cylinder, they gradually flow towards the middle of the primary mixing disc through the upper arc surface of the primary mixing disc. Meanwhile, the second motor drives the third rotating shaft to rotate, which in turn drives the primary mixing disc to rotate. This causes the V-shaped protrusions on the primary mixing disc to collide with the various raw materials, thereby breaking them up and scattering them to facilitate mixing.

Detailed Implementation

[0031] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.

[0032] Please see Figures 1-5 This utility model provides a parallel feeding device, including a feeding device 002, and a support device 001 for supporting the feeding device 002 is installed at one end of the feeding device 002.

[0033] The support device 001 includes a support frame 100. A first motor 110 for controlling the rotation of the feeding device 002 is installed at the upper end of the support frame 100. A first rotating shaft 111 is installed at the output end of the first motor 110. A first flange 112 is fixedly installed at the lower end of the first rotating shaft 111. A plurality of bolts 113 are installed in the middle of the first flange 112.

[0034] The feeding device 002 includes multiple raw material cylinders 200 for holding raw materials. After the first motor 110 is started, the first rotating shaft 111 drives the feeding device 002 to rotate synchronously, which facilitates the feeding of raw materials into the raw material cylinders 200.

[0035] The upper end of the raw material cylinder 200 is fixedly installed with a feed pipe 210, and the upper end of the feed pipe 210 is equipped with a sealing cap 211 for sealing the upper end of the feed pipe 210, so as to prevent the volatilization of potentially volatile organic compounds in the raw material and to prevent harmful gases after volatilization from causing harm to the human body.

[0036] The lower end of the raw material cylinder 200 is equipped with a first discharge pipe 220 for facilitating the delivery of raw materials into the raw material primary mixing cylinder 400. A valve 221 is installed in the middle of the first discharge pipe 220 to control the rate of material descent. By rotating the switch on the valve 221, the amount of raw material passing through the first discharge pipe 220 can be adjusted, thereby adjusting the material flow rate. The adjustment is made according to the amount of raw material in the raw material cylinder 200. When the amount of raw material is large, the amount of raw material passing through the first discharge pipe 220 per minute is large, and when the amount of raw material is small, the amount of raw material passing through the first discharge pipe 220 per minute is small. This ensures that when the first discharge pipe 220 with a large amount of raw material is almost finished, there is still raw material in the first discharge pipe 220 with a small amount of raw material for mixing, so that the raw materials are mixed more thoroughly.

[0037] An observation window 230 is provided in the middle of the raw material cylinder 200 to facilitate observation of the amount of raw material inside the raw material cylinder 200 and to adjust the feeding rate of raw material in each raw material cylinder in real time.

[0038] The lower end of the raw material cylinder 200 is equipped with a support plate 300 for supporting multiple raw material cylinders 200. A second rotating shaft 310 is fixedly installed at the middle of the upper end of the support plate 300. A second flange 311 is fixedly installed at the upper end of the second rotating shaft 310 for limiting the position of the support plate 300 with bolts 113. The second flange 311 and the first flange 112 are fitted together and fastened with bolts 113. This allows the first rotating shaft 111 to rotate the support plate 300 in conjunction with the second rotating shaft 310, so that the raw material cylinders 200 at the upper end of the support plate 300 can be turned to the front end, facilitating the feeding of raw materials into the raw material cylinders 200.

[0039] The feeding device 002 includes a raw material mixing cylinder 400 for preliminary mixing of raw materials. The raw material mixing cylinder 400 includes a cylinder body 410. The upper end of the cylinder body 410 is machined with a plurality of mounting ports 411 for limiting the first discharge pipe 220. The output end of the first discharge pipe 220 is connected to the interior of the cylinder body 410 through the mounting ports 411 to facilitate preliminary mixing of various raw materials inside the cylinder body 410. The lower end of the cylinder body 410 is equipped with a second discharge pipe 412. The raw materials that have been preliminarily mixed are conveyed to the next step through the second discharge pipe 412.

[0040] The raw material initial mixing cylinder 400 is equipped with an initial mixing component 420 to facilitate the mixing of raw materials. The initial mixing component 420 includes an initial mixing disc 421, and the upper end of the initial mixing disc 421 is machined with an arc-shaped surface for guiding the raw materials. By setting the arc-shaped surface, the raw materials can flow to the middle of the initial mixing disc 421, increasing the fluidity of the raw materials and facilitating the mixing of raw materials.

[0041] The feed pipe 210 has multiple discharge holes 422 in its middle for feeding raw materials. Multiple V-shaped protrusions 423 for stirring the raw materials are fixedly installed at the upper middle part of the primary mixing disc 421. A third rotating shaft 424 is installed in the middle of the primary mixing disc 421, and threaded holes are machined at the bottom of the third rotating shaft 424. The primary mixing disc 421 is fixed to the bottom of the third rotating shaft 424 by bolts. A second motor 425 is installed at the upper end of the third rotating shaft 424 to control the rotation of the primary mixing disc 421.

[0042] When multiple raw materials fall from the top of the cylinder 410, they gradually flow towards the middle of the primary mixing disc 421 through the upper arc surface. The second motor 425 drives the third rotating shaft 424 to rotate, which in turn drives the primary mixing disc 421 to rotate. This causes the V-shaped protrusions 423 on the primary mixing disc 421 to collide with the multiple raw materials, thereby breaking up and disrupting the raw materials to facilitate mixing.

[0043] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
