Description

Technical Field

[0001] The utility model belongs to the technical field of neutralizers, and particularly relates to a novel non-clogging sulfur fumigation neutralizer. Background Art

[0002] The sulfur fumigation neutralizer is a key equipment for the clarification process in the sugar factory. In the process of sucrose production, the juice squeezed out of sugarcane by the press is called sugarcane juice. The sugarcane juice is filtered with a curved screen and sent to the sulfur fumigation neutralizer. At the same time, sulfur gas with a certain temperature and density, that is, sulfur dioxide gas, is also sent to the sulfur fumigation neutralizer. In the sulfur fumigation neutralizer, the sulfur gas is mixed with the sugarcane juice to form a sulfurous acid mixture. The sulfurous acid mixture is discharged from the neutralizer, and lime milk (Ca(OH)2) is added to the sulfurous acid mixture to react and generate calcium sulfite (CaSO3). The non-sugar impurities (such as colloidal suspended matter and pigments) in the mixed juice are removed by the adsorption of calcium sulfite.

[0003] The clarity of sugarcane juice is related to the amount of sulfur gas and the spray volume of sugarcane juice. In the sulfur fumigation neutralizer, the sugarcane juice is sprayed out from the nozzle at a certain flow rate after being pressurized, and then meets the sulfur gas and reacts. When changing the spray volume of sugarcane juice, the traditional sulfur fumigation neutralizer usually stops the sulfur fumigation neutralizer and the related equipment that feeds the sugarcane juice into the sulfur fumigation neutralizer, and then manually blocks some nozzles to meet the needs of sugarcane juice with different spray volumes. However, this method greatly affects production efficiency.

[0004] Therefore, there is an urgent need for a sulfur fumigation neutralizer that can flexibly adjust the spray volume of sugarcane juice and improve production efficiency. Utility Model Content

[0006] In view of the above problems, the utility model provides a novel non-clogging sulfur fumigation neutralizer, which comprises: a juice inlet chamber and a vacuum chamber and a distribution plate arranged between the juice inlet chamber and the vacuum chamber, the top of the juice inlet chamber is provided with an actuator and a lifter, the juice inlet chamber is provided with a sugarcane juice inlet, and the vacuum chamber is provided with a sulfur gas inlet; a first adjustment hole is provided at the center of the distribution plate, a plurality of second adjustment holes are provided on the distribution plate around the first adjustment hole, a first nozzle is provided on the first adjustment hole, and a second nozzle is provided on the second adjustment hole.

[0007] A second valve stem is connected to the first nozzle, one end of which passes through the top of the juice inlet chamber to be connected to the actuator, and the other end of the second valve stem extends into the first nozzle; a first valve stem is connected to the second nozzle, one end of which passes through the top of the juice inlet chamber to be connected to the lifter, and the other end of the first valve stem extends into the second nozzle.

[0008] The aperture of the first adjustment hole is larger than that of the second adjustment hole, and the apertures of the plurality of second adjustment holes are set to be the same aperture or to be different apertures.

[0009] Preferably, the first nozzle is vertically arranged on the first adjustment hole, so that the first nozzle can spray sugarcane juice vertically toward the vacuum chamber; a plurality of second nozzles are obliquely arranged on the second adjustment hole and uniformly inclined toward the center position of the distribution plate, so that the second nozzles can obliquely spray sugarcane juice toward the vacuum chamber.

[0010] Preferably, the lower end of the first nozzle passes through the first adjustment hole and extends into the interior of the vacuum chamber, and the upper end of the first nozzle is connected to the juice inlet chamber so that the upper end opening of the first nozzle is flush with the inner surface of the lower end of the juice inlet chamber.

[0011] Preferably, the lower end of the second nozzle passes through the second adjustment hole and is flush with the inner top surface of the upper end of the vacuum chamber, and the upper end of the second nozzle extends into the interior of the juice inlet chamber.

[0012] Preferably, a sealing ring is connected between the second nozzle and the first valve stem; and a sealing sleeve is connected between the first valve stem and the lifter.

[0013] Preferably, the first valve stem includes a first valve stem body and a valve flap connected to the end of the first valve stem body, the valve flap extends into the interior of the second nozzle, and the first valve stem body passes through the top of the juice inlet chamber and is connected to the lifter.

[0014] Preferably, the second valve stem includes a second valve stem body and a valve needle portion connected to the end of the second valve stem body, the valve needle portion extends into the first nozzle, and the second valve stem body passes through the top of the juice inlet chamber and is connected to the actuator.

[0015] Preferably, a guide seat is connected to the top of the juice inlet chamber, and the actuator is connected to the guide seat.

[0016] Preferably, a hand hole is provided on the juice inlet chamber, an observation hole is provided on the vacuum chamber, a throat is connected to the lower end of the vacuum chamber, and a tail pipe is connected to the lower end of the throat.

[0017] Preferably, the actuator is an electric actuator, a manual actuator or a pneumatic actuator.

[0018] Compared with the prior art, the novel non-clogging sulfur fumigation neutralizer provided by the utility model has the following advantages:

[0019] (1) Different adjustment holes are set on the distribution plate so that the new non-clogging sulfur fumigation neutralizer can be equipped with different nozzles. Among them, the first nozzle on the first adjustment hole is used for continuous adjustment during the reaction process, and the second nozzle on the second adjustment hole is used for switch adjustment during the reaction process. Under normal circumstances, the second nozzle is in a non-clogging state. That is, the first nozzle is in dynamic adjustment during the reaction process, and the multiple second nozzles are switched according to the situation. For example, some of the second nozzles are closed for blockage treatment and opened when needed, so that the entire adjustment process becomes flexible.

[0020] (2) The multiple second adjustment holes with different apertures are set on the distribution plate, making the adjustment process more flexible. Because as an adjustment hole, its aperture determines the specifications of the nozzle, and the spray volume of nozzles of different specifications is different. When the same aperture is used, the spray volume of each nozzle is the same. During adjustment, for example, when the three second nozzles are closed, the spray volume of sugarcane juice is reduced, achieving the purpose of reducing the spray volume of sugarcane juice, but at the same time, the sugarcane juice is reduced too little, and the adjustment effect is not very good. At this time, since the second adjustment holes of different sizes are set, the second nozzles can be the same or different. During adjustment, the second nozzle can be selected according to actual needs. The second nozzle is used as a switch adjustment, and the first nozzle is adjusted according to the fluctuation of the squeeze volume. In this way, the adjustment effect of the sugarcane juice spray volume is more in line with expectations. Therefore, the setting of the aperture of the second adjustment hole used as a switch further improves the flexibility of adjustment.

[0021] (3) The spray volume of the first nozzle and the second nozzle are controlled independently, and the spray volume of each second nozzle is also controlled independently. The spray volume on the first nozzle is controlled by the second valve stem and the actuator. The actuator controls the lifting and lowering of the second valve stem to control the length of the second valve stem extending into the first nozzle, thereby controlling its spray volume. The spray volume of the second nozzle is controlled by the first valve stem and the lifter. The end of the first valve stem is directly blocked on the second nozzle by the lifter. Similarly, the end of the first valve stem can be removed from the second nozzle to control the opening and closing of the second nozzle. By individually controlling the opening and closing of each second nozzle and individually controlling the first nozzle, the spray volume of sugarcane juice entering the vacuum chamber is adjusted, thereby achieving flexible adjustment.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following is a description of the embodiments of the present invention based on its overall structure.

[0030] Figure 1 and Figure 2 This is a schematic diagram of the structure of a novel non-clogging sulfur fumigation neutralizer provided by the utility model. Figure 3 This is a schematic diagram of the structure of the distribution plate provided by the utility model, see Figure 1 , Figure 2 and Figure 3 The novel non-clogging sulfur fumigation neutralizer comprises: a juice inlet chamber 1 and a vacuum chamber 2 and a distribution plate 3 arranged between the juice inlet chamber 1 and the vacuum chamber 2, the top of the juice inlet chamber 1 is provided with an actuator 4 and a lifter 5, the juice inlet chamber 1 is provided with a sugarcane juice inlet 10, and the vacuum chamber 2 is provided with a sulfur gas inlet 20; a first adjustment hole 31 is provided at the center position of the distribution plate 3, a plurality of second adjustment holes 32 are provided on the distribution plate 3 around the first adjustment hole 31, a first nozzle 61 is provided on the first adjustment hole 31, and a second nozzle 62 is provided on the second adjustment hole 32.

[0031] The first nozzle 61 is connected to a second valve stem 7, one end of which passes through the top of the juice inlet chamber 1 to be connected to the actuator 4, and the other end of the second valve stem 7 extends into the first nozzle 61; the second nozzle 62 is connected to a first valve stem 8, one end of which passes through the top of the juice inlet chamber 1 to be connected to the lifter 5, and the other end of the first valve stem 8 extends into the second nozzle 62.

[0032] The aperture of the first adjustment hole 31 is larger than the aperture of the second adjustment hole 32 , and the apertures of the plurality of second adjustment holes 32 are set to be the same aperture or different apertures.

[0033] See also Figure 1 , Figure 2 and Figure 3 The novel non-clogging sulfur fumigation neutralizer provided in the above embodiment has the following working principle:

[0034] Sugarcane juice is squeezed out of the sugarcane through the squeezer, and the juice enters the juice inlet 10 into the juice inlet chamber 1, and is sprayed into the vacuum chamber 2 through the first nozzle 61 and the second nozzle 62. The high-speed sprayed juice will form a negative pressure inside the vacuum chamber 2, and the negative pressure will draw the external sulfur through the sulfur inlet 20, so that the sulfur enters the vacuum chamber 2 and is collected together with the sugarcane juice.

[0035] The juice inlet chamber 1 is arranged at the upper end of the vacuum chamber 2, and the distribution plate 3 is connected between the juice inlet chamber 1 and the vacuum chamber 2. The distribution plate 3 is used to fix the first nozzle 61 and the second nozzle 62.

[0036] See also Figure 1 , Figure 2 and Figure 3 , the distribution plate 3 is configured as a circular distribution plate. A first adjustment hole 31 is provided at the center of the distribution plate 3, and the first adjustment hole 31 can connect the juice inlet chamber 1 and the vacuum chamber 2. A plurality of second adjustment holes 32 are provided around the first adjustment hole 31. In a preferred embodiment, the aperture size of each second adjustment hole 32 is different, and in some optional embodiments, the aperture sizes of the second adjustment holes 32 are the same.

[0037] As a preferred embodiment, the aperture size of each second adjustment hole 32 is different, and its technical advantage is that it can make the adjustment of the sugarcane juice spraying amount more flexible. As for the adjustment hole, its aperture determines the specification of the nozzle, and the spraying amount of nozzles of different specifications is different. In the case of setting nozzles of different specifications, the nozzles can be combined and selected at will during adjustment, so that the adjustment is more flexible and the adjustment effect is better. For example, three second nozzles with the same spraying amount can be selected, and then three other second nozzles with the same spraying amount can be selected, and then the first nozzle can be used for adjustment.

[0038] See also Figure 1 , Figure 2 and Figure 3 When the new non-clogging sulfur fumigation neutralizer is working, the first regulating hole 31 is used as a continuous regulating hole, that is, the flow rate of sugarcane juice is stabilized by continuously adjusting the spray volume of the first nozzle 61, thereby stably maintaining negative pressure to absorb sulfur gas. The second regulating hole 32 is used as a switch regulating hole, which not only maintains negative pressure, but also is used to adjust the clarity of sugarcane juice.

[0039] In the new non-clogging sulfur fumigation neutralizer, sulfur gas is dissolved in the sugarcane juice at a certain concentration to generate a sulfurous acid mixture. The clarity of the sugarcane juice is closely related to the concentration of sulfur gas dissolved in the sugarcane juice in the new non-clogging sulfur fumigation neutralizer. If the dissolved density is small, the generated calcium sulfite is not enough to absorb impurities in the sugarcane juice, and if the dissolved density is too large, it will cause excessive consumption of lime. Therefore, it is necessary to ensure that the solubility of sulfur gas in the sugarcane juice is stable within a certain range. Therefore, for the second regulating hole 32 used as a switch-type regulating hole, the second nozzle 62 configured thereon can assist in adjusting the concentration of sulfur gas entering the vacuum chamber 2. When only one of the first nozzles 61 is used, its nozzle cannot adapt to the fluctuation of the pressing amount. The sugarcane juice squeezed out of the sugarcane by the squeezer directly enters the new non-clogging sulfur fumigation neutralizer. When only a single nozzle is used, it can only be applied to the requirements of low pressing amount. However, the production site is often a high pressing amount. For the state of high pressing amount and constant fluctuation of pressing amount, if only the first nozzle 61 is used, it is not easy to adjust, which is easy to cause large fluctuations in sulfur fumigation intensity and pH value. The simultaneous use of the first nozzle 61 and the plurality of second nozzles 62 can meet the regulation requirements of a high pressing volume and a constantly fluctuating pressing volume.

[0040] like Figure 3 As shown, eight second adjustment holes 32 are arranged on the distribution plate 3, and eight second nozzles 62 are configured. During the adjustment process, the first adjustment hole 31 is used as a continuous adjustment hole. When the first nozzle 61 cannot be adjusted, that is, the adjustment of the first nozzle 61 alone cannot meet the sugarcane juice processing requirements, the second adjustment holes 32 of different numbers and sizes are used for adjustment according to the fluctuation of the squeezed amount, that is, according to the sugarcane juice on the side of the sugarcane juice inlet 10. That is, according to the fluctuation of the squeezed amount, the second nozzles 62 of different numbers and different spraying amounts are used for adjustment, so that the spraying amount and flow rate of the sugarcane juice in the vacuum chamber 2 are stable, and then the solubility of sulfur in the sugarcane juice is stabilized within a certain range. In the adjustment process, the second adjustment holes 32 of different apertures can be configured with second nozzles 62 of different specifications, and the second nozzles 62 of different specifications can be more suitable for the fluctuation of the squeezed amount.

[0041] In a preferred embodiment, the number of the second adjustment holes 32 is 6 or more. As a more preferred embodiment, for example, the number of the second adjustment holes 32 is 9 or 12.

[0042] See also Figure 1 , Figure 2 and Figure 3, the spray volume and flow rate of the first nozzle 61 and the second nozzle 62 are set to be independently controlled, and each second nozzle 62 is independently controlled. In the utility model, the first nozzle 61 is controlled by the second valve stem 7 and the actuator 4, and the actuator 4 can operate the length of the second valve stem 7 extending into the first nozzle 61 to adjust the spray volume and flow rate of the sugarcane juice on the first nozzle 61. The second nozzle 62 is controlled by the first valve stem 8 and the lifter 5, and the first valve stem 8 is raised and lowered by the lifter 5 to control the spray volume and flow rate of the sugarcane juice on the second nozzle 62. In some preferred embodiments, a pull rod is set at the top of the juice inlet chamber 1, and the pull rod is connected to the first valve stem 8, and the first valve stem 8 is pulled up and down by the pull rod. The first nozzle 61 and the second nozzle 62 are set to be independently controlled to flexibly adjust the spray volume of sugarcane juice entering the vacuum chamber 2.

[0043] In a preferred embodiment, the actuator 4 is an electric actuator, a manual actuator or a pneumatic actuator. At the same time, a manual actuator, an electric actuator or a pneumatic actuator can also be used to control the first valve stem 8. In the utility model, Figure 2 Reference numeral 17 denotes an actuator for controlling the first valve stem 8, which may be a manual actuator, an electric actuator, or a pneumatic actuator.

[0044] See also Figure 1 , Figure 2 and Figure 3 In a preferred embodiment, the first nozzle 61 is vertically arranged on the first adjustment hole 31, so that the first nozzle 61 can vertically spray sugarcane juice toward the vacuum chamber 2; a plurality of second nozzles 62 are obliquely arranged on the second adjustment hole 32, and uniformly inclined toward the center position of the distribution plate 3, so that the second nozzles 62 can obliquely spray sugarcane juice toward the vacuum chamber 2.

[0045] As a preferred embodiment, both the first nozzle 61 and the second nozzle 62 are conical nozzles. The first nozzle 61 is vertically arranged on the first adjustment hole 31 in the vertical direction. The upper end of each second nozzle 62 is deflected outward, that is, deviated from the center of the distribution plate 3, and the lower end of each second nozzle 62 is deflected inward, that is, close to the center of the distribution plate 3, so that the second nozzle 62 can be tilted on the second adjustment hole 32. Under this setting, the sugarcane juice sprayed by the first nozzle 61 and the second nozzle 62 can collide with each other, and a more stable negative pressure is formed through collision friction. The stable negative pressure makes the sulfur gas suction force stronger, which meets the needs of high extraction volume.

[0046] See also Figure 1 , Figure 2 and Figure 3 In a preferred embodiment, the lower end of the first nozzle 61 passes through the first adjustment hole 31 and extends into the interior of the vacuum chamber 2, and the upper end of the first nozzle 61 is connected to the juice inlet chamber 1, so that the upper end opening of the first nozzle 61 is flush with the inner surface of the lower end of the juice inlet chamber 1. In the above preferred embodiment, except that the top opening of the first nozzle 61 needs to be connected to the juice inlet chamber 1, the remaining part of the first nozzle 61 is arranged in the vacuum chamber 2. This method can make the sugarcane juice on the first nozzle 61 spray into the vacuum chamber 2 from the middle position in the vacuum chamber 2, thereby forming a stable negative pressure in the vacuum chamber 2.

[0047] See also Figure 1 , Figure 2 and Figure 3 In a preferred embodiment, the lower end of the second nozzle 62 passes through the second adjustment hole 32 and is flush with the inner top surface of the upper end of the vacuum chamber 2, and the upper end of the second nozzle 62 extends into the juice inlet chamber 1. In the above preferred embodiment, the bottom of the second nozzle 62 is connected to the vacuum chamber 2 so that the second nozzle 62 can be connected to the vacuum chamber 2, and the remaining part of the second nozzle 62 is arranged in the juice inlet chamber 1. In this way, the sugarcane juice sprayed from the second nozzle 62 can be sprayed from the top of the vacuum chamber 2 into the vacuum chamber 2.

[0048] See also Figure 1 , Figure 2 and Figure 3 In a preferred embodiment, a sealing ring 9 is connected to the second nozzle 62, and the sealing ring 9 is used for contact sealing between the first valve stem 8 and the second nozzle 62. In the above preferred embodiment, the first valve stem 8 is blocked on the second nozzle 62, so the second nozzle 62 and the first valve stem 8 need to be sealed to avoid juice leakage here during the adjustment process. For example, during the adjustment process, according to the amount of sugarcane juice on the side of the sugarcane juice inlet 10, when it is necessary to block the juice of part of the second nozzle 62, if juice leakage still occurs during the blocking process, the adjustment effect is difficult to meet expectations. Similarly, a sealing sleeve 16 is connected between the first valve stem 8 and the lifter 5, and the sealing sleeve 16 is also used for sealing to prevent sugarcane juice from leaking from this part.

[0049] See also Figure 1 , Figure 2 and Figure 3In a preferred embodiment, the first valve stem 8 includes a first valve stem body 81 and a valve clap 82 connected to the end of the first valve stem body 81, the valve clap 82 extends into the second nozzle 62, and the first valve stem body 81 passes through the top of the juice inlet chamber 1 and is connected to the lifter 5. In the above preferred embodiment, the valve clap 82 is directly blocked inside the second nozzle 62, blocking the entire second nozzle 62. When adjusting, the lifter 5 or the pull rod or the external actuator is used to control the valve clap 82 to directly block the second nozzle 62, and the number of blocked second nozzles 62 is controlled according to actual conditions.

[0050] Specifically, in some other preferred embodiments, the valve flap 82 does not need to extend into the interior of the second nozzle 62 , but directly blocks the second nozzle 62 at the opening position of the second nozzle 62 .

[0051] See also Figure 1 , Figure 2 and Figure 3 In a preferred embodiment, the second valve stem 7 includes a second valve stem body 71 and a valve needle portion 72 connected to the end of the second valve stem body 71, the valve needle portion 72 extends into the first nozzle 61, and the second valve stem body 71 passes through the top of the juice inlet chamber 1 and is connected to the actuator 4. In the above preferred embodiment, the valve needle portion 72 is configured to be cylindrical at the upper end and conical at the lower end, and is configured according to the situation of the first nozzle 61.

[0052] See also Figure 1 , Figure 2 and Figure 3 In a preferred embodiment, a guide seat 13 is connected to the top of the juice inlet chamber 1, and the actuator 4 is connected to the guide seat 13. In the above preferred embodiment, a screw sleeve and other parts are connected to the guide seat 13, and the actuator 4 is installed on the guide seat 13 through the screw sleeve and other parts, and the screw sleeve and other parts can seal the second valve stem 7 to prevent the sugarcane juice in the juice inlet chamber 1 from leaking from the connection position between the second valve stem 7 and the juice inlet chamber 1.

[0053] See also Figure 1 , Figure 2 and Figure 3 In a preferred embodiment, a hand hole 11 is provided on the juice inlet chamber 1, and an observation hole 21 is provided on the vacuum chamber 2. In the above preferred embodiment, the hand hole 11 is convenient for observing the situation in the juice inlet chamber 1, and is also convenient for repairing the parts in the juice inlet chamber 1. The same is true for the observation hole 21.

[0054] See also Figure 1 , Figure 2 and Figure 3 In a preferred embodiment, the lower end of the vacuum chamber 2 is connected to a throat pipe 14, and the lower end of the throat pipe 14 is connected to a tail pipe 15. Specifically, the sugarcane juice and sulfur gas are mixed and collected at the throat pipe 14, and the sulfurous acid mixture generated later is discharged to the tail pipe 15 through the throat pipe 14, and the sugarcane juice after the sulfur fumigation neutralization reaction is completed is discharged from the tail pipe 15.

[0055] In summary, the new non-clogging sulfur fumigation neutralizer provided by the utility model can adjust the spray volume and flow rate of the sugarcane juice in the sulfur fumigation neutralization reaction based on the fluctuation of the sugarcane juice extraction in the sugar factory production control system, so that the sulfur fumigation intensity is stable, and can match the production control system to adapt to the change of sugarcane juice extraction from 30% to 120%, which is very convenient for process control.
