Abstract
Description
Technical Field
[0001] This utility model relates to the field of rinsing equipment technology, specifically to a rinsing structure for a vacuum filter. Background Technology
[0002] A vacuum filter press, also known as a vacuum filtration machine, is a device that uses negative pressure generated by a vacuum pump to achieve filtration and separation. It is widely used in liquid-solid separation processes in industries such as chemical, pharmaceutical, food, and environmental protection. The basic principle of a vacuum filter press is to create negative pressure on the filter medium (such as filter cloth or filter paper), allowing the liquid (filtrate) to pass through the filter medium while solid particles (filter cake) are retained on it.
[0003] HPMC, or hydroxypropyl methylcellulose, is a semi-synthetic, nonionic cellulose ether mixture. It is a white or off-white powder, odorless and tasteless, with viscoelastic properties. HPMC has wide applications in many fields.
[0004] HPMC typically requires rinsing with a vacuum filter during production to remove impurities such as ash and improve its purity.
[0005] Traditional vacuum filter presses typically use one or two fixed nozzles on the frame for cleaning. This limits the effectiveness of cleaning ash and other contaminants from the object being cleaned, resulting in longer washing times and poorer cleaning results. Utility Model Content
[0006] In view of this, the present invention provides a rinsing structure for a vacuum filter, which can achieve efficient and rapid cleaning of the object to be cleaned by setting multiple sets of position-adjustable rinsing components. This solves the problem that the spraying structure of the traditional vacuum filter usually involves fixing one or two fixed nozzles on the frame of the vacuum filter before cleaning, which has a limited range of washing effect on ash and other substances in the object to be cleaned, resulting in long washing time and poor washing effect.
[0007] To solve the above-mentioned technical problems, this utility model provides a rinsing structure for a vacuum filter. The rinsing structure is installed on the frame of the vacuum filter, and a water storage tank connected to the rinsing structure is installed below the frame. The rinsing structure includes spray pipes and a synchronous spacing adjustment component installed on the frame. A pair of spray pipes are installed on the synchronous spacing adjustment component, which can adjust the pair of spray pipes to move towards each other. The spray pipes and the water storage tank are connected by a water pump. This utility model can achieve convenient and quick adjustment of the position of the spray pipes through the synchronous spacing adjustment component, thereby greatly increasing the spraying range of the spray pipes. It solves the problem that the traditional rinsing structure of a vacuum filter usually involves fixing one or two fixed nozzles on the frame of the vacuum filter for cleaning, which has a limited range of washing effect on ash and other substances in the object to be cleaned, resulting in long washing time and poor washing effect. This invention greatly improves the cleaning efficiency.
[0008] The synchronization spacing adjustment component includes a slide rail mounted on the upper part of the frame, two sliders slidingly mounted inside the slide rail, and a drive unit on the slide rail to drive the two sliders to move in opposite directions.
[0009] Both sliders have threaded holes with opposite threads. A bidirectional screw is rotatably installed inside the slide rail. The bidirectional screw passes through the two sliders and is threadedly connected to the two sliders. The driving component includes a servo motor, and the output shaft end of the servo motor is connected to the bidirectional screw for transmission.
[0010] A bearing is provided between the output shaft end of the servo motor and the bidirectional screw. The slide rail has a mounting hole that matches the outer ring of the bearing. The outer ring of the bearing is fixed in the mounting hole. The end of the screw that connects to the servo motor is a smooth rod. The smooth rod is fixed to the inner side of the inner ring of the bearing. The output shaft of the servo motor is fixed to the outer side of the inner ring of the bearing.
[0011] Each slider is equipped with a fixing plate at its lower part, and each fixing plate is equipped with a spray pipe at its lower part. The spray pipe includes a diversion pipe located at the lower part of the fixing plate. There are two diversion pipes, and the two diversion pipes are connected to each other through a connecting pipe. Each diversion pipe has multiple water spray pipes on its inner side closest to the object to be sprayed, and multiple bamboo-joint pipes connected to it are also provided on the outer side of each diversion pipe.
[0012] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:
[0013] 1. This utility model can be started by rotating the output shaft of a servo motor. The rotating servo motor drives the bidirectional screw to rotate as well. In addition, the threaded connection between the two sliders with opposite screw threads and the guiding and limiting function of the slide rail on the sliders, the rotation of the bidirectional screw can drive the two sliders and their lower spray pipes to move towards each other along the slide rail. This enables spray cleaning of a larger area to be cleaned. Moreover, as the spray components move simultaneously in opposite directions, the impurities washed away are washed off, preventing them from remaining on the surface of the object. This results in better cleaning effect, higher cleaning efficiency, and more convenient and efficient operation.
[0014] 2. This utility model can guide and divert the spray liquid introduced into it through the diversion pipe, and spray it out through the spray pipe and bamboo joint pipe to achieve all-round and multi-angle rinsing spray operation on the object to be cleaned, resulting in better cleaning effect and higher efficiency.

Detailed Implementation
[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the appendices of the embodiments of this utility model. Figure 1-3 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.
[0020] like Figure 1-3As shown: This embodiment provides a rinsing structure for a filter press. The rinsing structure is mounted on the frame 100 of the filter press. A water storage tank 200 connected to the rinsing structure is located below the frame 100. The rinsing structure includes spray pipes 500 and a synchronous spacing adjustment component 300 mounted on the frame 100. A pair of spray pipes 500 are mounted on the synchronous spacing adjustment component 300, which can adjust the pair of spray pipes 500 to move in opposite directions. The spray pipes 500 are connected to the water storage tank 200 via a submersible pump. Inside the water tank 200, the outlet of the water pump is connected to the inlet of the spray pipe 500 via a connecting hose. This utility model can conveniently and quickly adjust the position of the spray pipe 500 through the synchronous spacing adjustment component 300, thereby greatly increasing the spray range of the spray pipe 500. This solves the problem that the spray structure of traditional vacuum filter machines usually involves fixing one or two fixed nozzles on the frame 100 of the vacuum filter machine for cleaning operations, which has a limited range of washing effect on ash and other substances in the object to be cleaned, resulting in long washing time and poor washing effect. This greatly improves the cleaning efficiency.
[0021] According to one embodiment of the present invention, such as Figure 1-3 As shown, the synchronous spacing adjustment component 300 includes a slide rail 310 disposed on the upper part of the frame 100, two sliders 320 are slidably disposed in the slide rail 310, and a drive member 330 is also disposed on the slide rail 310 to drive the two sliders 320 to move in opposite directions.
[0022] Both sliders 320 have threaded holes with opposite threads. A bidirectional screw 340 is rotatably mounted inside the slide rail 310. The bidirectional screw 340 passes through both sliders 320 and is threadedly connected to them. The driving component 330 includes a servo motor 331. The output shaft of the servo motor 331 is connected to the bidirectional screw 340. This invention can rotate the output shaft of the servo motor 331. The rotation of the servo motor 331 drives the bidirectional screw 340 to rotate as well. Combined with the threaded connection between the bidirectional screw 340 and the two sliders 320 with opposite threads, and the guiding and limiting function of the slide rail 310, the rotation of the bidirectional screw 340 can drive the two sliders 320 to move towards each other along the slide rail 310. This enables synchronous and rapid adjustment of the distance between the two sliders 320, making the operation more convenient and efficient.
[0023] According to another embodiment of the present invention, such as Figure 1 and Figure 2As shown, a bearing is provided between the output shaft end of the servo motor 331 and the bidirectional screw 340. The slide rail 310 has a mounting hole that matches the outer ring of the bearing. The outer ring of the bearing is fixed in the mounting hole. The end of the screw that connects to the servo motor 331 is a smooth rod. The smooth rod is fixed to the inner side of the inner ring of the bearing. The output shaft of the servo motor 331 is fixed to the outer side of the inner ring of the bearing. This utility model can realize the transmission connection between the output shaft of the servo motor and the screw through the bearing, which has higher transmission efficiency.
[0024] According to another embodiment of the present invention, such as Figure 1 and Figure 3 As shown, each slider 320 has a fixing plate 400 at its lower part, and each fixing plate 400 has a spray pipe 500 at its lower part. The spray pipe 500 includes two branch pipes 510 located at the lower part of the fixing plate 400, and the two branch pipes 510 are connected by a connecting pipe 511. Each branch pipe 510 has multiple water spray pipes 512 on its inner side near the object to be sprayed, and multiple bamboo pipes connected to the outer side of each branch pipe 510 are also provided thereto. The bamboo-joint tube 513 is a plastic tube. The tilt angle and length of the bamboo-joint tube 513 can be easily and quickly adjusted. Specifically, the operator holds the bamboo-joint tube 513 and bends and moves its nozzle to a suitable position. This utility model can guide and divert the spray liquid introduced into it through the diversion tube 510, and spray it out through the spray pipe 512 and the bamboo-joint tube 513 to achieve all-round and multi-angle rinsing spray operation on the object to be cleaned, resulting in better cleaning effect and higher efficiency.
[0025] How to use this utility model:
[0026] First, it needs to be clarified that this utility model mainly involves spray cleaning of impurities on the surface of objects. Taking HPMC's spray cleaning as an example, this utility model details its usage. When cleaning is required, the water pump is first started to pump water from the storage tank 200 into the diversion pipe 510. Then, the output shaft of the servo motor 331 is started to rotate cyclically. This utility model can rotate by starting the output shaft of the servo motor 331. The rotating servo motor 331 drives the bidirectional screw 340 to rotate as well. Combined with the threaded connection between the bidirectional screw 340 and the two sliders 320 with opposite threads, and the guiding and limiting function of the slide rail 310 on the sliders 320, the rotation of the bidirectional screw 340 can... The two sliders 320, along with their lower spray pipes 500, move towards each other along the slide rail 310, thereby achieving spray cleaning of a larger area to be cleaned. Furthermore, the simultaneous movement of the spray components away from each other washes away impurities, preventing them from remaining on the object's surface. This invention achieves efficient and rapid cleaning of the object by setting multiple sets of adjustable spray components. It solves the problem that traditional filter presses typically use one or two fixed nozzles on the frame 100 for cleaning, resulting in limited washing effectiveness for ash and other substances, leading to longer washing times and poorer cleaning results. This invention offers better cleaning results, higher cleaning efficiency, and more convenient and efficient operation.
[0027] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0028] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
