Description
Technical Field
The invention belongs to the field of jet pumps, and particularly relates to a material distribution device for a nozzle feed inlet of a jet pump along with vibration.
Background
Jet pumps are important unit operations in chemical industry, and are fluid machinery and mixed conveying recoil equipment which transfer energy and mass by utilizing the strong shearing and severe turbulent diffusion effects between high-speed jet and sucked fluid. The jet pump has the characteristics of simple structure, stable process, convenient installation, strong process adaptability, low production cost and the like, so that the jet pump has wider and wider application range, and can replace water ring type, rotary vane type and reciprocating vacuum pumps under certain vacuum conditions. The patent describes a solid-liquid mixing jet pump which has dual functions of solid-liquid mixing and conveying, and the most remarkable characteristic is the conveying of solid powder, such as corn starch and the like. High efficiency is obtained if a jet pump is used to deliver soluble salts with relatively stable physical and chemical properties, such as sodium sulfate, sodium carbonate, sodium chloride, etc. The high-efficiency jet pump system has wide application prospect, and can be widely applied to solid-liquid mixed conveying in the fields of petroleum, chemical industry, medicine, food and the like.
The jet pump system achieves the aim of conveying a solid-liquid mixture by using high-speed flowing liquid sprayed by a jet nozzle, and in the process, the feeding efficiency of the jet nozzle of the jet pump directly influences the efficiency of the jet pump system, so that how to improve the efficiency of the jet pump system is very important. It is noted that the material distribution device at the feed inlet of the nozzle of the vibration type jet pump also has certain influence on the overall efficiency of the system. For example, the humidity of powder products (such as starch) added into a jet pump nozzle is too high, the humidity of powder is too high due to wet weather, and excessive feeding of operators can cause the powder at the discharge opening of the jet pump jet nozzle to be excessively accumulated into blocks, commonly called as 'lump materials', so that the powder cannot freely slide down by the gravity of the powder and cannot be sucked into the jet pump nozzle under the jet vacuum generated by the jet pump jet nozzle, and the idle operation of a jet pump system is caused, namely the efficiency bottleneck of the jet pump is generated. In addition, when the feeding amount of an operator is too large or too fast, a large amount of powder is impacted to enter the jet pump nozzle, so that the gas in the jet pump nozzle is instantly extruded to form reverse impact of the powder, and the operator is injured, and the phenomenon is commonly called choking. Therefore, under the condition of not accompanying the feeding hole distributing device of the vibration type jet pump nozzle, an operator cannot stir and distribute the powder by using an iron stick, because a large amount of dust can exist in a workshop when the operator feeds the jet pump nozzle, and the dust can explode when meeting open fire. Therefore, the operator can only use a stick to distribute and dredge the bottleneck of the feed opening, which artificially increases the investment of labor cost. Use the stick probably to lead to the saw-dust to fall into in the hopper, and can not solve the problem that scraps of paper and cellosilk on the wrapping bag fall into in the hopper with it, product quality is difficult to guarantee. Therefore, the traditional system design method does not carry out material distribution synergy on the nozzle feeding port of the jet pump, causes the investment of a large amount of manpower and material resources, and has possible potential safety hazards, so that the efficiency of the jet pump system is reduced, and the jet pump system is not economical and environment-friendly.
The accompanying vibration type jet pump nozzle feed inlet distributing device is developed on the basis of research of 'high-efficiency jet nozzles capable of continuously adjusting positions of jet spray pipes' (ZL 201410539286.0), and the specific structure is shown in the attached drawing 2 and is used as an economical jet pump nozzle submachine obtained by a mother machine through tests. In the prior art, a person obtains a jet nozzle with higher efficiency on the basis of long-term practical application and experiments, and in comparison, the efficiency of the jet nozzle is lower than that of a jet pump nozzle additionally provided with a material distribution device along with a feeding hole of a vibrating jet pump nozzle.

Along with the working principle of the vibrating type jet pump nozzle feed inlet distributing device (see the attached figure 1):
(1) pouring the powder into a hopper;
(2) when the powder is poured into the hopper, the powder is under the impact of self gravity, and the elasticity sensitivity of the material distribution device is higher along with the nozzle feed inlet of the vibration type jet pump, so that the vibration can be generated, the impact force of the powder is buffered, and the concentrated powder is subjected to dispersed material distribution, so that the distribution is more reasonable.
The vibration comes from two parts: the vibration generated by the impact of the powder has the characteristic of intermittent vibration; the jet pump system operates to produce mechanical vibrations that are characterized as continuous and stable, i.e., as long as the jet pump system is operating properly. The forced vibration of the material distributing device at the feed inlet of the nozzle of the vibration type jet pump also effectively weakens the condition of material choking;
(3) when severe 'lump materials' occur, the lifting rod (2-8) or the butterfly nut (2-3) can be slightly knocked downwards by a rubber hammer to vibrate the materials. The vibration hooks (2-9) can push the powder downwards to flow and make the powder vibrate to become more loose and easy to flow, so that the condition of lump materials is relieved to a certain extent;

As the cross-sectional area of the pressurizing chamber A is gradually reduced, the potential energy of the liquid is reduced and the kinetic energy of the liquid is increased, so that the jet speed of the liquid is greatly increased when the liquid passes through the outlet of the pressurizing chamber A, and a jet effect is formed. The liquid flowing at high speed is sprayed into a diffusion shape through the mixing chamber B, the occupied space volume is increased, part of air is entrained to enter the expansion chamber C, the space volume of the liquid is further increased, and then the liquid enters the conveying pipeline with the same diameter as the outlet end of the expansion chamber C. The high velocity flow of liquid creates a vacuum in the process through the pumping chamber a to the expansion chamber C. Solid powder (such as starch) is fed into a vacuum mixing chamber B through a hopper 1 and a material distributor 2 along with a vibrating jet pump nozzle feed inlet, and the powdery solid which slides freely is sucked into the mixing chamber, mixed with high-speed slurry which enters continuously and then enters an expansion chamber C. The mixed slurry returns to the slurry return tank through the conveying pipeline, is sucked by the high-pressure liquid conveying pump again, and then is injected into the jet nozzle to form a cycle.
The method for assembling the material distribution device at the nozzle feed inlet of the jet pump along with vibration comprises the following steps:
and (3) installing a lifting rod and a vibration hook: 6 vibration hooks (2-9) are respectively and uniformly welded on the lifting rod (2-8). And finishing the installation of the lifting rod and the vibration hook.
The steel wire cage (2-1) is welded with the spring seat (2-2): the material distribution device is installed along with a nozzle feed port of a vibration type jet pump: firstly, six suspended ends on the upper side of the steel wire cage (2-1) are respectively inserted into 6 holes on the spring seat (2-2), then the six steel wires are respectively welded with the spring seat (2-2), and then the 6 steel wires are respectively welded with two horizontal circular steel wire rings inside the steel wire cage (2-1). Meanwhile, the steel wire cage (2-1) is also manufactured.

And finishing the installation of the material distribution device along with the nozzle feed port of the vibration type jet pump.
It is suggested that the actual position of the vibrating hooks (2-9) after installation should be adjusted to the position in fig. 1, which should not be too high nor too low, otherwise, the cloth effect is not good. The position can also be adjusted by the wing nut (2-3).
