Description

Technical Field

[0001] The utility model relates to the technical field of wet granulators, in particular to a spray gun fixing structure of a wet granulator. Background Art

[0002] Wet granulator is a mechanical device used to process wet powder or block dry material into the required granules. It mixes powdered or liquid raw materials with additives through specific processes and mechanical structures, and then gradually forms granular products under the action of stirring or spraying. When the wet granulator is working, the slurry (such as syrup or fluid extract) needs to be injected into the mixed material through a spray gun. However, the traditional spray gun is a fixed spray gun, and it is impossible to adjust the depth of the nozzle into the granulation pot according to the amount of material in the granulation pot or the spraying requirements of different materials.

[0003] The prior art has made many improvements to the above defects. For example, the patent with publication number CN205216787U discloses a locking screw for a spray gun of a wet granulator, which includes a tube seat for fitting a spray gun tube, a locking nut is fitted on the outside of the tube seat, a locking seal ring is provided on the inner wall of the locking nut, and the locking nut and the tube seat slide together to squeeze the locking seal ring. Although the patent can adjust the height of the nozzle at the end of the spray gun tube in the granulator cylinder according to the needs of different drug production, it only evaluates the distance the spray gun tube moves up and down by visual inspection, and cannot know the specific distance the spray gun tube moves, and cannot accurately control the specific spray angle of the spray gun.

[0004] In addition, the patent with publication number CN217910269U discloses a wet granulator spray gun. The outer circular surface of the tube body in the patent is engraved with scale lines.

[0035] The spray gun fixing structure of the wet granulator of the utility model is mainly used for installation on the granulation pot 4, the mounting seat 1 is fixed on the granulation pot 4, and can be fixed by welding, the rotating mounting seat 2 is movably connected to the mounting seat 1, and the granulation pot 4 is a common structure in the prior art. The spray gun tube body 3 is locked on the rotating mounting seat 2, and the rotating mounting seat 2 can drive the spray gun tube body 3 to rotate around the axis of the mounting seat 1, and the arc-shaped scale line 5 set on the mounting seat 1 cooperates with the angle indicator 7 to display the rotation angle of the rotating mounting seat 2 and the spray gun tube body 3. The staff can see the specific rotation angle of the angle indicator 7 from the angle observation port 6. The above structure can accurately adjust the horizontal rotation angle of the spray gun tube body 3.

[0036] In the present invention, the angle observation port 6 can be a notch directly provided on the rotating fixed seat 2, or a transparent material structure, such as glass, provided on the rotating fixed seat 2. For the convenience of observation, the present invention preferably adopts the angle observation port 6 as a notch provided on the rotating fixed seat 2. The angle indicator 7 can be the edge line of the angle observation port 6, or a pointer can be directly provided at the angle observation port 6. For the convenience of reading, the present invention preferably adopts the angle indicator 7 as a pointer.

[0037] The spray gun tube body 3 is movably connected to the rotating fixed seat 2 to facilitate the spray gun tube body 3 to move up and down in the rotating fixed seat 2. The specific method can adopt the common adjustment method in the prior art, such as the tube body adjustment method in the patent with publication number CN205216787U and the patent with publication number CN217910269U.

[0038] In one embodiment of the utility model, the angle indicator 7 is a pointer, and the spray gun tube body 3 is provided with linear scale lines 8 distributed along the axial direction of the spray gun tube body 3, and the main scale lines of the linear scale lines 8 are aligned with the needle tip at the end of the pointer. The linear scale lines 8 can be set to accurately control the specific distance of the spray gun tube body 3 moving up and down, and the main scale lines and the needle tip at the end of the pointer are easy to observe. The staff can see the arc scale lines 5 and the linear scale lines 8 at the same position at the same time, which is highly operable.

[0039] like Figures 1 to 9 As shown, the mounting seat 1 includes a first mounting portion 101 and a second mounting portion 102, and the rotating fixed seat 2 includes a first fixing portion 201 and a second fixing portion 202; the second mounting portion 102 is fixed on the external granulating pot 4, the first fixing portion 201 is located at the upper end of the first mounting portion 102, and the first fixing portion 201 is rotatably connected to the first mounting portion 101. The above structure facilitates the matching of the mounting seat 1 and the rotating fixed seat 2, and the mounting seat 1 and the rotating fixed seat 2 are hollow T-shaped structures as a whole, and the horizontal portion of the mounting seat 1 with the T-shaped structure is movably connected to the horizontal portion of the rotating fixed seat 2 with the T-shaped structure.

[0040] like Figure 3 and Figure 4 As shown, the top of the second fixing portion 202 in the utility model is provided with a scale alignment line 16 extending radially along the second fixing portion 202. The scale alignment line 16 is located above the angle observation port 6, and the end of the scale alignment line 16 is aligned with the main scale line in the linear scale line 8. The scale alignment line 16 is mainly used as a reference line for the main scale line in the linear scale line 8. In actual operation, the main scale line in the linear scale line 8 is aligned with the scale alignment line 16, so that the linear scale line 8 and the pointer can be aligned, which is easy to operate and has strong practicality.

[0041] like Figure 1 , Figures 5 to 9 As shown, in one embodiment of the utility model, a guide screw 9 is provided at the bottom of the first fixing part 101, and an arc-shaped adjustment groove 10 corresponding to the guide screw 9 is provided on the first mounting part 201; the upper end of the guide screw 9 is fixed on the first fixing part 101, and the lower end passes through the arc-shaped adjustment groove 10 and is locked by a butterfly nut 11. The guide screw 9 and the arc-shaped adjustment groove 10 are in clearance fit, and the guide screw 9 can slide in the arc-shaped adjustment groove 10 as the rotating fixing seat 2 rotates. After sliding to the required position, the butterfly nut 11 at the bottom of the guide screw 9 is tightened, and the butterfly nut 11 presses the first mounting seat 1 upward along the guide screw 9, so that the first mounting part 101 and the first fixing part 201 are closely fitted. The utility model adopts the butterfly nut 11 to facilitate the hand-tightening operation, without the need for additional tools, which greatly improves the convenience and efficiency of the operation.

[0042] like Figures 1 to 4 as well as Figures 7 to 9 As shown, a locking screw 12 cooperating with the spray gun tube 3 is provided on the rotating fixing seat 2, and the locking screw 12 is arranged on the second fixing portion 202, and a screw hole 13 cooperating with the locking screw 12 is opened on the second fixing portion 202.

[0043] After the locking screw 12 passes through the screw hole 13, it contacts the spray gun tube body 3. As the locking screw 12 is tightened, its end abuts against the spray gun tube body 3 and applies a certain pressure to the spray gun tube body 3, thereby locking the spray gun tube body 3 on the rotating fixed seat 2. When it is necessary to adjust the height of the spray gun tube body 3, loosen the locking screw 12, then pull the spray gun tube body 3 to the corresponding height to adjust the depth of the spray gun tube body 3 extending into the granulating pot 4, and then lock it. A protective head is also provided at the end of the locking screw 12 that contacts the spray gun tube body 3, and its material can be a material with a soft texture and a large friction coefficient such as rubber, cotton fabric and leather. The protective head is fixed at the end of the locking screw 12, and the protective head contacts the spray gun tube body 3 when the locking screw 12 is tightened. Since the protective head is soft and has a large friction coefficient, the protective head can play a certain buffering role when the locking screw 12 squeezes the spray gun tube 3. The large friction coefficient makes the friction force on the surface of the spray gun tube 3 greater, ensuring that the spray gun tube 3 is not easy to slide when locked, thereby improving the stability of the device.

[0044] During the process of adjusting the height of the spray gun tube body 3, the rotating fixed seat 2 is always fixed on the mounting seat 1, and the rotating fixed seat 2 is not rotated; during the process of adjusting the angle of the rotating fixed seat 2, the spray gun tube body 3 is locked on the rotating fixed seat 2, and the height adjustment operation of the spray gun tube body 3 is not performed.

[0045] like Figure 1 , Figure 8 and Fig. 9 As shown, it also includes a feed pipe 14 and a nozzle 15. The feed pipe 14 is arranged at the upper end of the spray gun tube body 3, and the nozzle 15 is arranged at the lower end of the spray gun tube body 3.

[0046] The nozzle 15 in the utility model is arranged at the end of the spray gun tube body 3 extending into the granulating pot 4, and the feed pipe 14 is connected to the external pump body, and when feeding is required, the material is fed into the spray gun tube body 3 through the pump body. Both the feed pipe 14 and the nozzle 15 are common structures in the prior art, such as the corresponding structure disclosed in the patent with publication number CN205216787U.

[0047] An example of an installation process of the present invention is given below.

[0048] When installing the device of the utility model, the mounting seat 1 is first fixed on the granulating pot 4; then the rotating fixed seat 2 is fixed on the mounting seat 1, rotated to the required angle, and locked by the butterfly nut 11, and the rotation process is observed through the angle indicator 7; then the spray gun tube body 3 is extended into the granulating pot 4 through the rotating fixed seat 2 and the mounting seat 1, and the spray gun tube body 3 is adjusted to the corresponding height, and fixed by the locking bolt, and the height adjustment process of the spray gun tube body 3 is observed through the linear scale line 8. In the above process, the spray gun tube body 3 can also be first installed on the rotating fixed seat 2 and the height is adjusted, and then the rotating fixed seat 2 is installed on the mounting seat 1 and the angle is rotated.

[0049] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only a specific implementation method of the utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions and improvements made within the scope of the utility model should be included in the protection scope of the utility model.
