Description

TECHNICAL FIELD

[0001] The utility model relates to hollow fiber membrane processing equipment technical field especially, it relates to a feeding hopper with dispersion function. BACKGROUND

[0002] In the water treatment membrane application field, PVDF membrane material is widely applied because of its excellent acid and alkali resistance, chemical corrosion resistance, weather resistance, biocompatibility and good processability. The material is usually divided into suspension material and emulsion material because of different processing technology, and the two materials are in the state of powder. When producing and preparing the spinning dope, solvent is generally added first and then PVDF polymer is added, and the uniformity of the mixture of the two is crucial to the quality and stability of the subsequent produced membrane filaments.

[0003] Because of the dissolution characteristics of the powder material, it is light and easy to float, and it is easy to form a mass during the dissolution process due to the coating of the solvent, which brings trouble to the further dissolution of the raw material. For high-viscosity spinning dope, the increase of the viscosity of the polymer powder added in the early stage will affect the dissolution and uniform mixing of the powder added later. Using the conventional feeding hopper, the powder material will be added to the dissolving kettle in one direction. Because the continuously added powder material cannot be dissolved in time, the powder material accumulates at one position, and under the action of the stirring paddle, it is mixed with the solvent to form a mass, which needs a long time to dissolve. Using the interval feeding method invisibly increases the feeding time, affecting the overall production efficiency and the high efficiency of the process matching. SUMMARY

[0004] Therefore, the purpose of the utility model is to provide a feeding hopper with dispersion function to solve the technical problem that the existing feeding hopper has a single feeding direction when discharging, causing the powder to accumulate and affecting the dissolution efficiency.

[0011] As the preferred technical scheme of the utility model, the guide component is an impeller rotatably arranged on one side of the support close to the end face of the discharge port, the impeller has a driving blade surface, so that when the small block powder hits the driving blade surface, the driving blade surface can convert the hitting potential energy into the driving force for the rotation of the impeller relative to the support, thereby further dispersing the powder through the rotating impeller.

[0012] As the preferred technical scheme of the utility model, the funnel body comprises an upper shell and a lower shell telescopically arranged at the head and tail.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical scheme and advantage of the utility model more clear and obvious, the following is in combination with specific embodiment, and the utility model is further explained in detail.

[0025] As Figure 1 , Figure 2 Indicated, a kind of feeding funnel with dispersion function, is located at the feed inlet of dissolving kettle, including: funnel body with feed inlet 2 and discharge outlet 3, the caliber of feed inlet 2 is greater than the caliber of discharge outlet 3, to form the discharge channel of upper wide lower narrow;Crushing component is arranged at discharge outlet 3, and crushing component is used to crush large block powder in discharge channel into small block powder and make it dispersed;Guide component is arranged at discharge outlet 3, and guide component is used to release small block powder after dispersion through discharge outlet 3 into dissolving kettle in random direction;

[0026] The above technical scheme can make the powder disperse into the inside of the dissolving kettle, prevent the powder from accumulating in one place, and when used, the funnel body is installed at the feeding opening of the dissolving kettle, the powder to be added is poured into the funnel body from the feeding opening 2, due to the structure of the funnel being narrow at the top and wide at the bottom, the powder feeding speed is not too fast, so as to avoid forming a group, when the powder contacts the crushing component, the two collide, so as to crush the large powder into small powder and make the small powder disperse on the guide component, the guide component releases the small powder into the dissolving kettle through the discharging opening 3 in a random direction, due to the non-uniqueness of the release direction, the powder can be effectively prevented from accumulating in one place, and the small area of accumulation is diffused to a larger area, so that the powder presents a "spreading" effect, and the powder accumulation into a block is further avoided, and the dissolving effect and stirring efficiency of the liquid are improved.

[0027] As shown in Figure 3 In this embodiment, the crushing component is a support 5 arranged on the inner wall of the discharging opening 3; preferably, the support 5 is designed in a cross structure.

[0028] The above technical scheme can preliminarily disperse the powder, and when the powder collides with the support 5, the powder is dispersed into small pieces, and the small pieces of powder fall from the gap between the support 5 and the inner wall of the funnel body.

[0029] As shown in Figure 3 In this embodiment, the guide component is an impeller 6 rotatably arranged on the side of the support 5 close to the end face of the discharging opening 3, and the impeller 6 has a driving blade surface, so that when the small pieces of powder collide with the driving blade surface, the driving blade surface can convert the collision potential energy into the driving force for the rotation of the impeller 6 relative to the support 5, so as to further disperse the powder through the rotating impeller 6.

[0030] The above technical scheme can utilize the collision potential energy of the powder to drive the rotation of the impeller 6, so as to further disperse the powder through the rotation of the impeller 6, when the powder is poured, the powder passes through the support 5 to be dispersed along the powder feeding channel of the funnel body, and the dispersed powder drives the rotation of the impeller 6, the rotating impeller 6 further disperses the powder, the small area of accumulation is diffused to a larger area, so that the powder presents a "spreading" effect, and the powder accumulation into a block is further avoided, and the dissolving effect and stirring efficiency of the liquid are improved.

[0031] As shown in Figure 1 and Figure 2As shown, in the present embodiment, the funnel body comprises a top shell 1 and a bottom shell 4 which are telescopically connected; preferably, the top shell 1 and the bottom shell 4 are welded to each other to form an integral body, the top shell 1 is composed of a first vertical section 101, a first inclined section 102 and a second vertical section 103; the bottom shell 4 is composed of a third vertical section 401, a second inclined section 402, a third inclined section 403 and a fourth inclined section 404, the third vertical section 401 is connected with the second vertical section 103;

[0032] The above technical solution can avoid the powder from falling on the stirring shaft of the dissolving kettle. Since the lower end of the funnel body is designed to be bent, the added raw materials finally enter along the wall of the dissolving kettle. This has the advantage that the powder added along the wall of the kettle can be taken away by the spiral belt of the stirring paddle in time and mixed into the liquid, avoiding the powder from accumulating on the main shaft of the stirring paddle in the downward mode along the discharge port 3.

[0033] Working principle:

[0034] The funnel body is designed to be wide at the top and narrow at the bottom. The feed port 2 of the funnel body is completely matched with the feed port of the dissolving kettle. On the one hand, it can prevent the added raw materials from leaking out of the gap between the funnel body and the dissolving kettle. On the other hand, it can also avoid the dusting of the powder to some extent, which brings trouble to the operators and poses a safety hazard of dust inhalation. At the same time, the design of being wide at the top and narrow at the bottom facilitates the addition of raw materials, and the structure of the narrowed lower end of the funnel can control the speed of discharging, avoiding the formation of powder lumps.

[0035] The funnel body is designed to be bent, so that the added raw materials finally enter along the wall of the dissolving kettle. This has the advantage that the powder added along the wall of the kettle can be taken away by the spiral belt of the stirring paddle in time and mixed into the liquid, avoiding the powder from accumulating on the main shaft of the stirring paddle in the downward mode along the discharge port 3.

[0036] The discharge port 3 of the funnel adopts a cross-shaped support 5, and the center of the cross is installed to the impeller 6. This design structure further improves the dispersion effect of the powder without the formation of powder lumps. When the powder is added, it first passes through the support 5 for dispersion, and then passes through the impeller 6, which drives the rotation of the impeller 6. The rotating impeller 6 further disperses the powder from a small area to a larger area, so that the powder presents a "spreading" effect, further avoiding the formation of powder lumps, improving the dissolution effect of the liquid and the stirring efficiency.

[0037] It is worth mentioning that the funnel can be made of stainless steel or plastic resistant to solvent corrosion. In actual use, if the production formula does not change, the feeding funnel does not need to be cleaned frequently. After use, it is stored in a large sealed bag. This can avoid the moisture of the water-absorbing raw materials and prevent dust from falling and introducing other impurities.

[0038] It should be understood by those of ordinary skill in the art that the above discussion of any of the embodiments is merely exemplary and is not intended to suggest the scope of the present application (including the claims) is limited to these examples; the above embodiments or technical features among different embodiments can also be combined, the steps can be implemented in any order, and there are many other changes of different aspects of the present application as described above, which are not provided in details for the sake of brevity.

[0039] The present application is intended to cover all such alternatives, modifications, and variations as fall within the broad scope of the appended claims. Accordingly, any and all such alternatives, modifications and variations should be included within the scope of the present application.
