Description

Technical Field

[0001] This utility model relates to the field of belt juicer cleaning technology, and in particular to a reciprocating spray 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] The rinsing process in the existing technology is unidirectional, meaning that the rinsing water is discharged as wastewater for treatment. To ensure the rinsing effect, the existing technology usually requires a large amount of pure water to ensure the cleanliness of the press belt after washing. Utility Model Content

[0004] In response to the shortcomings of the existing production technology, the applicant provides a reciprocating spray structure with a reasonable structure. Compared with the traditional rinsing structure, it reduces the number of nozzles, increases the water pressure, and uses high-pressure, low-flow pure water for reciprocating rinsing, thereby reducing the water consumption per cleaning cycle.

[0005] The technical solution adopted in this utility model is as follows: A reciprocating spray structure includes a spray pipe that reciprocates axially, wherein at least one end of the spray pipe is provided with a power source, and the power source drives the spray pipe to reciprocate. The spray surface of the spray pipe is constant, and the spray surface moves unidirectionally as the spray pipe moves.

[0006] As a further improvement to the above technical solution: The spray pipe is equipped with an installation reference, which is set at both ends of the initial position of the spray pipe, and a spraying space is reserved between the two installation references.

[0007] A protective cover is provided between the two mounting bases, and the spray pipe reciprocates through the protective cover.

[0008] The length of the nozzle movement path on the spray pipe is less than the length of the protective cover in the axial direction of the spray pipe.

[0009] The mounting base is equipped with a support seat, and the power source is located at one of the support seats.

[0010] Rollers are provided on the support seats at both ends, and the rollers on each support seat clamp the spray pipe on both sides.

[0011] The rollers are symmetrically arranged on both sides of the spray pipe in the radial direction.

[0012] The roller is a non-powered roller.

[0013] The spray surface of the nozzles on the spray pipe covers the width of the pressing belt to be cleaned.

[0014] The end of the spray pipe facing away from the power source is connected to a flexible pipe or flexible joint.

[0015] The beneficial effects of this utility model are as follows: This application, based on high-lift, high-pressure water, reduces the number of nozzles to decrease the amount of water sprayed per unit time and lower water costs. Theoretically, due to the already designed high-pressure, high-lift cleaning structure, the high-pressure, high-lift cleaning water can compensate for the reduced cleaning effect caused by the fewer nozzles.

[0016] To further optimize the cleaning effect by reducing the number of nozzles, this application concentrates the nozzles on a specific section of the spray pipe, replacing the conventional evenly distributed nozzle design. This localized design shortens the distance between adjacent nozzles, making the sprayed water mist more planar rather than a single bundle, resulting in a larger cleaning coverage area. This application also designs a servo structure for the spray pipe, driving it to reciprocate at high speed. This transforms the cleaning action from unidirectional spray cleaning to multiple high-pressure reciprocating spray cleanings per unit time, which can be understood as changing from a single cleaning to high-frequency multiple cleanings. During the high-frequency multiple cleaning process, the press belt is in two states: being sprayed and the spraying is paused. When spraying is paused, the residual sugary juice continues to fall under its own weight and the influence of the water flow. When it is sprayed again, the cleaning effect is enhanced, resulting in a better cleaning effect compared to a single continuous atmospheric pressure spray.

[0017] The spray pipe is equipped with a protective cover. The cover protects the spray pipe and nozzles and prevents water from flowing in other directions. It also serves as a reference structure for the spray pipe. The cover works in conjunction with the installation reference to provide a unidirectional motion reference for the spray pipe and prevent it from moving in other degrees of freedom.

[0018] Compared with traditional cleaning structures, the spray system showed a more significant water-saving effect during practical operation as the width of the pressing belt to be cleaned increased. Conventional cleaning structures require a larger volume of water to cover the pressing belt, while the high-frequency, high-pressure reciprocating spray cleaning method used in this application can cover the pressing belt by moving the system and can achieve precise water usage, thus the total water consumption is not greater.

[0022] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0023] like Figure 1 and Figure 2 As shown, the reciprocating spray structure of this embodiment includes a spray pipe 3 that reciprocates axially. At least one end of the spray pipe 3 is provided with a power source 1, which drives the spray pipe 3 to reciprocate. The spray surface of the spray pipe 3 is constant, and the spray surface moves unidirectionally as the spray pipe 3 moves.

[0024] The spray pipe 3 is equipped with an installation reference 2, which is set at both ends of the initial position of the spray pipe 3, and a spraying space is reserved between the two ends of the installation reference 2.

[0025] A protective cover 6 is provided between the two mounting references 2, and the spray pipe 3 reciprocates through the protective cover 6.

[0026] The length of the movement path of the nozzle 4 on the spray pipe 3 is less than the length of the protective cover 6 in the axial direction of the spray pipe 3.

[0027] Mounting reference 2 is equipped with a support 7, and power source 1 is located at one of the support 7.

[0028] Rollers 702 are provided on the two end support seats 7, and the rollers 702 on each support seat 7 are clamped on both sides of the spray pipe 3.

[0029] Rollers 702 are symmetrically arranged on both sides of the spray pipe 3 in the radial direction.

[0030] Roller 702 is a non-powered roller.

[0031] The spray surface of the nozzle 4 on the spray pipe 3 covers the width of the pressing belt to be cleaned.

[0032] The end of the spray pipe 3 facing away from the power source 1 is connected to a flexible pipe or flexible joint 5.

[0033] The specific structure and working principle of this application are as follows: This application relates to belt juicers and provides a spray system for cleaning the juicer belt. This spray system significantly reduces the amount of water used for cleaning by using high-pressure, reciprocating spraying. After collection, the collected cleaning water contains less pulp than conventional cleaning water and can be used for a second pressing, thereby increasing the juice yield and sugar content of the juice.

[0034] The overall principle of this application is as follows: Figure 1 As shown, a spray system is installed on the basis of a belt juicer. The spray system includes a plunger pump, which pressurizes pure water to 6-8 MPa. At this pressure, the pure water can easily penetrate the pressing belt and wash away any residual juice, pulp, and pulp stuck in the holes of the pressing belt.

[0035] The main improvement in this application lies in how the sprinkler system achieves water conservation; therefore, it only addresses... Figure 1 The spray pipe part will be further explained. Other structures of the juicer, such as the water delivery system, can use existing technologies.

[0036] like Figure 2 As shown, the spray pipe 3 structure includes a power source 1, which can be a cylinder or a power source 1. Taking the power source 1 as an example, the power source 1 is installed on an external frame, and the frame is used as the installation reference 2 of the overall spray structure. The direction of movement of the power source 1 is required to be parallel to the installation reference 2 so that the power source 1 can drive the spray pipe 3 to reciprocate along the installation reference 2.

[0037] The spray pipe 3 is a straight pipe, with one end of the spray pipe 3 closest to the power source 1 being a closed end. The other end of the spray pipe 3 is connected to the water outlet section using a connector 5. A flexible pipe can be used as the water outlet section, or a flexible connector 5 can be used to allow the spray pipe 3 to reciprocate axially. A high-pressure water nozzle 4 is installed on the spray pipe 3. The high-pressure water nozzle 4 can be a commercially available part, combined with a plunger pump, to spray high-pressure water at a pressure of 6-8 MPa.

[0038] A protective cover 6 is installed outside the spray pipe 3, with the opening of the protective cover 6 facing the extrusion belt to be sprayed. The protective cover 6 is fixed to the mounting base 2, allowing relative sliding between the spray pipe 3 and the protective cover 6.

[0039] In this embodiment, the number of nozzles 4 is less. The nozzles 4 can be linearly arrayed on the spray pipe 3, or a small number can be set on a certain section of the spray pipe 3. When the spray pipe 3 moves axially back and forth, it drives the nozzles 4 to reciprocate and spray the pressing belt at high pressure to clean the pressing belt.

[0040] To further reduce the moving resistance of the spray pipe 3, support seats 7 are respectively installed at both ends of the spray pipe 3 on the mounting reference 2. The main body of the support seat 7 is made of bent steel or metal plate, and a through groove 701 is reserved on the main body. A set of rollers 702 is installed on each through groove 701. The rollers 702 are symmetrically arranged in the radial direction of the spray pipe 3. A set of two rollers 702 clamps the two sides of the spray pipe 3. When the spray pipe 3 moves, the two unpowered rollers 702 are used to reduce frictional resistance, while the main body of the support seat 7 is used to ensure that the movement of the spray pipe 3 is on a constant straight line.

[0041] The design concept of this application is to use ultra-high head, high-pressure water at a low flow rate to clean the pressing belt. A plunger pump pressurizes pure water to 6-8 MPa, a pressure easily penetrating the pressing belt, and then performs reciprocating spray cleaning. This spraying method, with fewer nozzles and higher water pressure, aims to save water and also results in a higher concentration of washing water, suitable for secondary pressing. Because the washing water contains a certain amount of sugar, the juice will have a higher sugar content after the secondary pressing.

[0042] Compared to traditional systems, this system uses only 1 / 5 to 1 / 6 of the water. Actual tests show that the wider the pressing belt, the more nozzles (4) are eliminated from the traditional spray structure, resulting in a more significant water-saving effect. It also eliminates the need for investment in belt washing water filtration equipment and filter residue conveying equipment. While saving water, it also reduces equipment investment, decreases wastewater treatment volume, and lowers the evaporation rate of subsequent evaporators.
