Description

Technical Field

[0001] This utility model relates to the technical field of belt juicer cleaning structure, and in particular to a juicer washing belt water recovery structure. Background Technology

[0002] Traditional cleaning systems for belt juicers involve placing a water collection tray beneath the juicer. Water from cleaning the upper and lower belts falls into this tray and is collected before flowing by gravity through pipes into a water filter screen located below. These screens can be curved, rotary, or vibrating. The filtered water then flows by gravity into a circulating water collection tank located below the screen. From there, a vertical multi-stage centrifugal pump pressurizes the filtered water and delivers it to the juicer's cleaning water inlet, creating a continuous cycle.

[0003] Because the filter screen can only remove coarse fibrous fruit residue, a significant amount of fine fruit residue remains on the pressing belt and in the washing water. This results in the need for a large amount of rinsing water to clean the pressing belt, leading to an increasing amount of fruit residue remaining in the washing water. Ultimately, a large amount of fruit residue-containing washing water requires additional wastewater treatment. This results in higher production costs. Utility Model Content

[0004] In response to the shortcomings of the existing production technology, the applicant provides a reasonably structured juicer washing and water recovery structure that achieves water conservation while also increasing the sugar content of the finished juice.

[0005] The technical solution adopted in this utility model is as follows: A juicer washing and water recovery structure includes a pipeline and a first water tank and a second water tank installed on the pipeline. The first water tank serves as the source of pure water for washing; the second water tank serves as a temporary storage location for the washing water after washing; the washing water in the second water tank is used as raw material for the second pressing.

[0006] As a further improvement to the above technical solution: The pipeline includes an outlet section, a return section, and a recovery section. The outlet section leads from the first water tank to the press belt, and the return section collects the washing water flowing out of the press belt. The spray direction of the water outlet section is towards the position of the circulating press belt to avoid the opening press roller.

[0007] The pressing belt is equipped with a fixed pulley on the side facing the ground, and the pressing belt forms a "V" shaped surface along the fixed pulley. The spray direction of the water outlet section is towards at least one inclined surface of the "V" shaped surface.

[0008] A water receiving tray is placed directly below the fixed pulley, and the output end of the water receiving tray is connected to the return water section.

[0009] The water receiving tray avoids the spray surface of the water outlet section.

[0010] The output end of the second water tank is connected to the recycling section and transported to the slag discharge machine or the second pressing pulp tank.

[0011] A parallel pipe leading to the return water section is extended from the juice output path of the belt juicer, and a valve connects the parallel pipe to the return water section.

[0012] The recycling section includes: The first section begins with the second water tank. A branch line branches off from one output end of the first section; the branch line sprays back onto the top of the press belt. The second section branches off from the output end of the first section; the second section leads to the slag discharge machine or the second pressing pulp tank.

[0013] Valve connections between the first section, branch line, and second section.

[0014] Both the first and second water tanks are connected to an external pure water source.

[0015] The beneficial effects of this utility model are as follows: This application provides a second water tank as a temporary storage location for the washing water, and uses the washing water as raw material for the second pressing. This improves the utilization rate of raw materials, and the washing water no longer needs to be treated separately as wastewater, thus reducing the wastewater treatment process.

[0016] The washing water is transported to the pulp discharge machine or the second pressing pulp tank, where it undergoes a mixing step before being sent directly to the second pressing stage. This allows the sugar content to be distributed more evenly within the mixture. Because the washing water contains a certain amount of sugar, the juice has a higher sugar content after the second pressing.

[0017] The juice output path features two parallel paths: a direct output path and an input path into a second water tank. This allows juice with more sediment from the later stages to be introduced into the second water tank and mixed with wash water, serving as raw material for a second pressing. This design ensures the purity of the output juice while also maximizing the utilization of sediment.

[0018] The design of this system is highly efficient and makes belt juicers equipped with this system ideal for concentrated juice processing lines, enabling efficient and low-loss juice extraction, energy saving and emission reduction, and economical operation. Attached Figure Description

[0021] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0022] like Figure 1 As shown, the juicer washing and water recovery structure of this embodiment includes a pipeline, and a first water tank 3 and a second water tank 4 installed on the pipeline. The first water tank 3 serves as the source of pure water for washing; the second water tank 4 serves as a temporary storage location for the washing water after washing; the washing water in the second water tank 4 is used as raw material for the second pressing.

[0023] The pipeline includes an outlet section 7, a return section 8, and a recovery section 9. The outlet section 7 leads from the first water tank 3 to the press belt 1, and the return section 8 collects the washing water flowing out of the press belt 1. The spray direction of the water outlet section 7 is towards the position of the circulating press belt 1, avoiding the opening press roller.

[0024] A fixed pulley 10 is installed on the side of the pressing belt 1 facing the ground. The pressing belt 1 forms a "V" shaped surface along the fixed pulley 10. The spraying direction of the water outlet section 7 is towards at least one inclined surface of the "V" shaped surface.

[0025] A water receiving tray 11 is supported directly below the fixed pulley 10, and the output end of the water receiving tray 11 is connected to the return water section 8.

[0026] The water receiving tray 11 avoids the spray surface of the water outlet section 7.

[0027] The output end of the second water tank 4 is connected to the recovery section 9, and the water is transported to the slag discharge machine 5 or the second pressing pulp tank.

[0028] On the juice output path of the belt juicer, there is a parallel pipe 14 that connects to the return water section 8, and the parallel pipe 14 is connected to the return water section 8 by a valve.

[0029] Recycling section 9 includes: The first segment, 901, originates from the second water tank, number 4. Branch 903 branches off from one output end of the first section 901; branch 903 sprays back to above the press belt 1. The second section 902 branches off from one output end of the first section 901; the second section 902 leads to the slag discharge machine 5 or the second pressing pulp tank.

[0030] Valve connections between section 901, branch line 903, and section 902.

[0031] Both the first water tank 3 and the second water tank 4 are connected to an external pure water source.

[0032] The specific structure and working principle of this application are as follows: Example 1: This application relates to a belt juicer and provides a cleaning structure for cleaning the juicer belt 1. This cleaning structure significantly reduces the amount of water used for cleaning through high-pressure water spraying, reciprocating spraying, and wastewater recycling. After collection, the cleaning wastewater contains less water than conventional cleaning water, resulting in a higher pulp content, which can be used for a second pressing, thereby increasing the juice yield and sugar content of the juice.

[0033] The overall principle of this application is as follows: Figure 1 As shown, a plunger pump 2 is installed on the basis of the belt juicer. The plunger pump 2 pressurizes the pure water to 6-8 MPa. The pure water under this pressure can easily penetrate the pressing belt 1 and wash off the juice, pulp and pulp stuck in the holes of the pressing belt 1.

[0034] The inlet of plunger pump 2 is connected to a first water tank 3, which is connected to an external pure water source, allowing pure water to be added to the tank at any time. After the plunger pump 2 draws pure water, it is delivered to the pipeline connected to the outlet of the plunger pump 2. The pipeline leads to the pulp discharge machine 5, where the pulp mixes with the fruit pomace inside the machine, increasing the moisture content of the pomace. The pomace output from the pulp discharge machine 5 after replenishment of water is used for subsequent secondary pressing.

[0035] Because the washing water contains a certain amount of sugar, the juice has a higher sugar content after the second pressing, and it can also further extract the juice remaining in the pulp.

[0036] The connecting pipeline between the first water tank 3, the plunger pump 2, and the slag discharger 5 includes the inlet section 6, the outlet section 7, the return section 8, and the recovery section 9.

[0037] Among them, the water inlet section 6 is the pipeline between the first water tank 3 and the plunger pump 2, and the plunger pump 2 draws pure water.

[0038] The pipeline leading out from one end of the plunger pump 2 is the water outlet section 7. After the plunger pump 2 pressurizes the pure water, it is delivered to the water outlet section 7. The water outlet of the water outlet section 7 is connected to several nozzles. The nozzles face the pressing belt 1, and the pressurized water in the nozzles sprays out to wash off the residual juice and pulp on the pressing belt 1.

[0039] To facilitate the collection of water from washing, such as Figure 1As shown, in this embodiment, a fixed pulley 10 is provided at the lowest section of the pressing belt 1, and this section of the pressing belt 1 is set into a downward converging cone shape. Directly below the fixed pulley 10, a water receiving tray 11 is provided. The washing water obtained after rinsing the pressing belt 1 with pure water is received by the water receiving tray 11 and sent to the return water section 8 connected to the water receiving tray 11. The return water section 8 sends the washing water to the second water tank 4 for storage.

[0040] The output end of the second water tank 4 is connected to a centrifugal pump 12. One end of the output of the centrifugal pump 12 is the recovery section 9 of the pipeline. The recovery section 9 is connected to the inlet of the slag discharge machine 5 and is mixed with the fruit pomace and input into the slag discharge machine 5. The slag discharge machine 5 outputs the water-replenished fruit pomace through the spiral blades.

[0041] Example 2: The difference between this embodiment and embodiment one is that one end of the output of the recovery section 9 can be directly connected to the second pressing pulp tank, and stored in the second pressing pulp tank for subsequent second pressing.

[0042] Example 3: The difference from Embodiment 1 or Embodiment 2 is that in this embodiment, a branch line 903 is led out from the recovery section 9. The branch line 903 extends above the pressing belt 1 of the belt juicer and has several nozzles 13. After passing through the recovery section 9 and the branch line 903, the washing water in the second tank is sprayed into the belt juicer from the nozzles 13, where the original belt juicer performs a second pressing of the washing water.

[0043] Branch 903 divides the recovery section 9 into the first section 901 and the second section 902, as follows: Figure 1 As shown, the first section 901 is the fork between centrifugal pump 12 and the second section 902 and branch line 903; the second section 902 extends from the fork to the slag discharge machine 5. Valves are installed on both the second section 902 and branch line 903. If the branch line 903 is long, two or more valves can be installed. At least one valve on branch line 903 should be located near the intersection to reduce residual washing water in branch line 903.

[0044] If the solution in Example 1 is to be used directly, and the washing water is input into the slag discharge machine 5, then the valve on branch line 903 should be closed; if the solution in this example is to spray the water to the original belt juicer's pressing belt 1, then the valve on the second section 902 should be closed. Branch line 903 or the recovery section 9 pipeline can be selected according to actual needs.

[0045] Example 4: Based on Embodiment 1, this embodiment improves the juice output path of the belt juicer. A parallel pipe 14 is opened on the juice output pipe 15, and the parallel pipe 14 is connected to the return water section 8. Valves are installed on both the parallel pipe 14 and the juice output pipe 15.

[0046] During the juicing process, when the pure juice is output, the valve on the juice output pipe 15 is opened and the valve on the parallel pipe 14 is closed, and the pure juice flows out from the juice output pipe 15. When the juice with more sediment is output, the valve on the juice output pipe 15 is closed and the valve on the parallel pipe 14 is opened. The thick juice with more sediment is stored in the second tank through the return water section 8 as the raw material for the second pressing.

[0047] Example 5: In this embodiment, the first water tank 3 is only replenished with pure water, while the second water tank 4 can be replenished with both pure water and washing water. The liquids in the first water tank 3 and the second water tank 4 do not flow into each other.

[0048] The design concept of this application is that, since the washing water contains a certain amount of sugar, the juice will have a higher sugar content after the second pressing, thereby improving the quality of the juice.

[0049] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
