Description

Technical Field

[0001] The utility model relates to the technical field of feeding devices, in particular to a feeding device for producing a papermaking dry strength agent. Background Art

[0002] Dry strength agents are an important class of chemicals used in the papermaking industry to increase the strength of paper. Many water-soluble polymers that can form hydrogen bonds with fibers can become dry strength agents. Dry strength agents are usually used to compensate for the decrease in paper strength caused by adding fillers or low-grade fibers (such as recycled fibers).

[0003] Dry strength agent is a new material, belonging to the field of fine chemical preparation and application technology. Dry strength agent needs to be fed with a feeding device during production. After searching, the prior art (application number: CN202021738355.8) records "a feeding device for dry strength agent production, including a cylinder, a support frame and an electric push rod, the outer periphery of the cylinder is connected to the support frame by bolts, the bottom end of the support frame is connected to the electric push rod by bolts, the bottom end of the electric push rod is connected to the support plate by bolts, the bottom end of the support plate is connected to the spring shock absorber by bolts, and the bottom end of the spring shock absorber is connected to the universal wheel by bolts. The utility model can provide stable support to the cylinder through the support frame by arranging a support frame, an electric push rod and a spring shock absorber. At the same time, the electric push rod can flexibly adjust the height of the device, improve the adjustability of the device, and meet different usage requirements. In addition, the spring shock absorber can reduce the vibration generated when the device is working, and improve the stability of the device."

[0004] Although the feeding device for dry strength agent production in the prior art achieves stable and anti-blocking feeding effects, the drum involved has a stirring and anti-blocking effect, but has no mixing effect on the dry strength agent. The production of dry strength agent requires a mixing reaction of multiple raw materials. Therefore, the above-mentioned device cannot quickly achieve the raw material mixing effect, which affects the overall production efficiency. Secondly, the existing feeding device has only one discharge port for feeding and discharging, that is, the subsequent processing equipment can only be fed through one discharge port, resulting in practical deviation.

[0010] Furthermore, the lower tube wall of the inclined tube is provided with flow holes at equal intervals, and a stopper is provided on the upper side of the flow holes and on the inner tube wall of the inclined tube.

[0011] Furthermore, drainage tubes are equidistantly connected to the lower outer wall of the inclined tube, and the upper ends of the drainage tubes are connected to the outside of the flow holes, and the lower ends of the drainage tubes pass through the top cover of the mixing tank and communicate with the inner cavity of the mixing tank.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figures 1 to 5As shown, the utility model provides a feeding device for papermaking dry strength agent production, including: a feeding assembly 1, a mixing tank 2 and a discharging assembly 3, a stirring motor 21 is installed at the upper end of the mixing tank 2, and a hydraulic rod 22 is connected to the outer wall of the mixing tank 2, and the lower end of the hydraulic rod 22 is connected to a base 23, the feeding assembly 1 is installed on the upper side of the mixing tank 2, and the feeding assembly 1 includes a feeding hopper 11 at the top, and a distribution pipe 12 is connected to the lower end of the feeding hopper 11, the discharging assembly 3 is connected to the lower end of the mixing tank 2, and the discharging assembly 3 includes a suction pump 31 connected to a discharge port 24 arranged at the bottom of the mixing tank 2, and the output end of the suction pump 31 is connected to a hollow disk 32.

[0025] In this embodiment, the feed assembly 1, the mixing tank 2 and the discharge assembly 3 constitute the main structure of the feeding device for papermaking dry strength agent production involved in this application, which is used for premixing and multi-channel output of raw materials in the production of papermaking dry strength agent.

[0026] Specifically, a self-locking universal wheel is provided at the bottom of the base 23, and four groups of hydraulic rods 22 are provided on the outer wall of the mixing tank 2 to achieve the effects of stable lifting and supporting.

[0027] like Figure 1 and Figure 3 As shown, a stirring shaft and stirring blades connected to the outside of the stirring shaft are provided inside the tank body of the mixing tank 2, and the upper end of the stirring shaft is connected to the output shaft end of the stirring motor 21, and the distribution pipe 12 includes an outer tube 121 on the outside, and the inner side of the outer tube 121 is connected to a conical block 124 through a connecting part 122, and the connecting part 122 is provided with annular distribution holes 123 arranged equidistantly.

[0028] Through the above technical solution, the mixing and stirring of the raw materials are achieved by using the stirring shaft and stirring blades; the conical block 124 and the distribution hole 123 inside the distribution pipe 12 are used to disperse the raw materials flowing through the feed hopper 11, achieving the effect of falling into the mixing tank 2 at multiple points.

[0029] like Figure 1 and Figure 2 In the embodiment, the feeding assembly 1 also includes an inclined tube 13, and the upper end of the inclined tube 13 is connected to the distribution hole 123, and the lower end of the inclined tube 13 is connected to the top cover plate of the mixing tank 2, and the lower side tube wall of the inclined tube 13 is equidistantly provided with flow holes 132, and a stopper 131 is provided on the upper side of the flow hole 132 and on the inner tube wall of the inclined tube 13, and the lower side outer wall of the inclined tube 13 is equidistantly connected with a drainage tube 14, and the upper end of the drainage tube 14 is connected to the outside of the flow hole 132, and the lower end of the drainage tube 14 passes through the top cover of the mixing tank 2 and is connected to the inner cavity of the mixing tank 2.

[0031] Through the above technical solution, the block 131 is used to achieve a local flow blocking effect on the raw material at each flow hole 132, thereby ensuring that the raw material can flow out from each flow hole 132 to the drainage tube 14. By setting up multiple groups of drainage tubes 14 and radially spreading them from the center of the mixing tank 2, the raw material falls into the mixing tank 2 over a large area, thereby improving the efficiency of premixing.

[0035] When in use, the raw materials are put into the feed hopper and dispersed through the distribution pipe, and then flow to the multiple inclined pipes connected to the lower side and the drainage pipe connected to the lower side of the inclined pipe, so that in the process of flowing into the mixing tank, they come into contact with the pre-added head raw materials over a large area, and then achieve rapid and uniform mixing in the stirring process, and then start the extraction pump to extract the mixed raw materials downward and flow through the hollow disk to each discharge pipe, and then when feeding multiple dry strength agent production equipment, it is only necessary to connect the outer end of the hose to the equipment feeding port at the corresponding position, and then open the valve on the outside of the discharge pipe, so that multiple equipment can be fed at the same time.

[0036] The feeding device for papermaking dry strength agent production of the utility model can effectively solve the problem that the feeding device for dry strength agent production in the prior art lacks a fast and uniform premixing structure and only feeds through one discharge port, resulting in practical deviation.
