Description

[0002] Polyacrylamide is a linear polymer. It is a hard glassy solid at room temperature. Its products include glue, latex, white powder, translucent beads and flakes. It has good thermal stability. It can be dissolved in water in any proportion, and the aqueous solution is a uniform transparent liquid. After long-term storage, the viscosity of the solution will decrease due to the slow degradation of the polymer, especially when the storage and transportation conditions are poor. Polyacrylamide is an extremely important oilfield chemical as a lubricant, suspending agent, clay stabilizer, oil displacement agent, water loss reducer and thickener.

[0003] In the granulation process of polyacrylamide, the columnar polyacrylamide needs to be cut to form granules.

[0027] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of 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.

[0028] The utility model is further described below in conjunction with embodiments.

[0029] Example: Refer to the attached Figure 1-4 As shown in the figure, a polyacrylamide granulation device includes a box body 100, a hot melt tube 110 is arranged on one side of the box body 100, a cooling tube is arranged at the outlet position of the hot melt tube 110, and a discharge port is arranged at the end of the cooling tube; two connecting plates 200 are fixedly connected to one side of the box body 100, a capsule 220 is fixedly connected to the upper side of the connecting plate 200, and a connecting tube 210 is arranged at the lower side of the connecting plate 200; and a piston tube 300 fixedly connected to the box body 100, a piston rod 310 is movably connected inside the piston tube 300, a cutting knife 311 is fixedly installed at the lower end of the piston rod 310, and an extrusion plate 320 is fixedly installed on one side of the cutting knife 311. Specifically, after the raw material is hot-melted through the set hot melt tube 110, the set cooling tube can make the raw material have a columnar structure, and cooperate with the set cutting knife 311 to achieve effective cutting of the raw material. It should be noted that the external air pump will intermittently inject gas into the piston tube 300 through the connecting tube 301, and then intermittently drive the cutting knife 311 to reciprocate in the vertical direction, so as to achieve uniform cutting of the raw material with a columnar structure.

[0030] A heating chamber is provided inside the box 100, a feed frame is provided at the upper side of the heating chamber, and a lap ring 111 is sleeved on the outer wall of the hot melt tube 110; the lap ring 111 is fixedly connected to the two connecting plates 200. The heating chamber provided inside the box 100 can fully melt the raw materials added from the feed frame into the box 100, and further, it should be noted that the spiral rod provided inside the hot melt tube 110 can fully melt the raw materials in a hot melt state.

[0031] The connecting pipe 210 is arranged in a bent shape, the outlet of the connecting pipe 210 corresponds to the position of the discharge port, and the connecting pipe 210 is connected to the capsule 220, and the upper side of the capsule 220 is connected and fixed to the lower surface of the extrusion plate 320. Specifically, through the connecting pipe 210, when the piston rod 310 drives the cutting knife 311 to move downward, the extrusion plate 320 that is fixedly connected to the cutting knife 311 will also move downward synchronously, and in combination with the capsule 220 arranged between the connecting plate 200 and the middle part of the extrusion plate 320, the capsule 220 will be compressed. After being compressed, in combination with the communication relationship between the capsule 220 and the connecting pipe 210, the gas in the capsule 220 will overflow from the connecting pipe 210, and in combination with the corresponding relationship between the outlet of the connecting pipe 210 and the outlet of the discharge pipe, it can effectively cool the cut raw materials, and it should be noted that, as an embodiment, a refrigeration mechanism is arranged in the capsule 220, which can cool the gas in the capsule 220.

[0032] The cutting knife 311 is in sliding cooperation with the outer end of the cooling tube, and an arc-shaped notch is provided in the middle of the cutting knife 311; the size of the arc-shaped notch matches the size of the discharge port. The upper end of the piston tube 300 is connected to the output end of the external air pump through the connecting tube 301; the position of the piston tube 300 corresponds to the position of the end of the cooling tube, and when the cutting knife 311 moves downward, the raw materials at the outlet of the discharge pipe can be cut. It should be noted that in the present application, the external air pump will intermittently inject gas into the piston tube 300, thereby driving the piston rod 310 to intermittently reciprocate in the vertical direction, and the sliding cooperation relationship between the cutting knife 311 and the end of the discharge pipe can effectively cut the columnar raw materials beyond the outlet of the discharge pipe and realize granulation.

[0033] It also includes a mounting ring 321 opened in the middle of the extrusion plate 320; an air outlet pipe 330 is clamped in the mounting ring 321, and a hose 331 connected to the output end of the external air cooler is provided at the upper end of the air outlet pipe 330. It also includes a bending plate 230 fixedly installed at the lower side of the connecting plate 200, and a sleeve 231 is fixedly installed on the upper side of the bending plate 230; a material receiving pipe 240 is elastically connected to the sleeve 231 through a spring 232. Furthermore, through the provision of the air outlet pipe 330, after the cutting is completed, after the air cooler is used to effectively cool the cut raw materials, it can also guide the raw materials to accurately land in the material receiving pipe 240;

[0034] Furthermore, the spring 232 provided in the present case can be intermittently connected to an external power source, so that it can intermittently contract and restore, thereby driving the receiving tube 240 to vibrate relative to the bending plate 230, thereby avoiding blockage at the receiving tube 240 or the situation in which the raw material adheres to the inner wall of the receiving tube 240 due to incomplete cooling of the raw material.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein by equivalents.
