Description

Technical Field

[0001] The utility model relates to the technical field of sandblasting machines, in particular to a water filter device for a water mist sandblasting machine. Background Art

[0002] In a water mist sandblasting machine, it is often necessary to mix water and sand materials together to improve the effect of workpiece processing. The use of water in the water mist sandblasting machine has high requirements. If the water contains a large amount of impurities, it is very easy to cause the sandblasting nozzle to become clogged. In order to avoid this situation, the water used needs to be filtered, so a water filter device is needed.

[0003] Application number CN95225013.6 describes a pneumatic wet sandblasting machine mounted on a wheeled frame. It features a sand tank, an air tank, and a combined spray gun connected via a pipe. The machine also features a water tank with a water inlet at the top and an air inlet on the side. The inlet is connected to the air tank via a pipe and a pressure reducing valve. The water outlet at the bottom of the water tank is connected via a water pipe to a water control valve and a water nozzle on the combined spray gun. This sandblasting machine reduces dust by spraying water, and boasts high blasting power. It is suitable for sandblasting large workpieces such as ships, large oil tanks, bridges, and roads.

[0004] However, the water flow of this device is directly sprayed onto the inner side of the filter element through the water nozzle. The filter element is subjected to excessive impact of the water flow, which can easily cause damage to the filter element during long-term spraying, thereby affecting the water filtering effect of the filter element.

[0005] In view of the above problems, it is urgent to carry out innovative design based on the water filter device structure of the original water mist sandblasting machine. Utility Model Content

[0006] The purpose of the utility model is to provide a water filtering device for a water mist sandblasting machine, so as to solve the problem proposed in the above background technology that the water flow of the device is directly sprayed onto the inner side of the filter element through the water nozzle, the filter element is subjected to excessive impact of the water flow, and the filter element is easily damaged during long-term spraying, thereby affecting the water filtering effect of the filter element.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a water filtering device for a water mist sandblasting machine, comprising a body, a supporting base fixedly mounted on the lower end of the body, a water inlet fixedly mounted on the upper end of the body, and an external water pipe connected to the outer side of the water inlet; a filter screen, the filter screen being fixedly mounted on the inner side of the body; a buffer assembly, the buffer assembly being arranged on the upper end of the filter screen; a knocking assembly, the knocking assembly being arranged at the lower end of the filter screen, and the knocking assembly being driven and operated by the buffer assembly, wherein the buffer assembly is adjusted in angle by the impact force of the water flow; the knocking assembly knocks the bottom of the filter screen by the angle change of the buffer assembly.

[0008] Preferably, the buffer assembly includes a rotating shaft and a buffer plate, the rotating shaft is rotatably connected to the inner side of the body, and the buffer plate is fixedly installed on the outer side of the rotating shaft.

[0009] Preferably, the buffer plate is arranged at the lower end of the water inlet.

[0010] Preferably, the buffer assembly also includes a slide groove, a telescopic spring, a sliding block and a support rod. The slide groove is opened on the inside of the body, and a telescopic spring is fixedly installed on the inside of the slide groove. The tail end of the telescopic spring is fixedly connected to the sliding block, and the sliding block is nested on the inside of the slide groove. The outer side of the sliding block is rotatably connected to the support rod, and the tail end of the support rod is rotatably connected to the bottom of the buffer plate.

[0011] Preferably, the support rods are arranged in two groups in a bilaterally symmetrical manner about the midpoint of the buffer plate.

[0012] Preferably, the knocking assembly includes a transmission belt, a concentric shaft and a cam, the concentric shaft shaft is connected to the rotating shaft shaft through the transmission belt, and the concentric shaft is rotatably connected to the inner side of the body, a cam is fixedly installed on the outer side of the concentric shaft, and the cam and the bottom of the filter are distributed correspondingly up and down.

[0013] Preferably, the cams are arranged in two groups symmetrically about the midpoint of the filter screen.

[0014] Compared with the prior art, the beneficial effect of the present invention is that the water filter device of the water mist sandblasting machine is provided with:

[0015] 1. Buffer structure. When water is supplied to the inner side of the body through an external water pipe, the water flow will be transported to the inner side of the body through the water inlet. During the transportation process, the water flow will impact the buffer plate placed at the lower end, thereby slowing down the flow rate of the water flow through the buffer plate. At the same time, the buffer plate will squeeze the support rod under the impact of the water flow, causing the support rod to rotate. The sliding block at the tail end of the support rod squeezes the telescopic spring and slides downward along the inner side of the slide groove. After the support rod rotates, the buffer plate loses the support of the support rod and rotates through the rotating shaft, thereby being tilted 45°. The water flow delayed at the upper end flows along the inclined surface of the buffer plate to the filter screen for filtration. Through the above structure, the filter screen is prevented from being damaged by excessive impact force of the water flow.

[0016] 2. Anti-clogging structure: When the water flow drives the buffer plate to rotate, the rotating shaft will simultaneously drive the concentric shaft to rotate through the connection of the transmission belt. The rotation of the concentric shaft will drive the cam to rotate together. The rotation of the cam will knock on the bottom of the filter screen. The knocking of the cam on the filter screen will cause the filter screen to vibrate. The generated vibration will shake out the impurities blocking the inside of the filter hole, preventing the filter hole from being blocked and affecting the water filtration effect;

[0017] Furthermore, when the water supply is stopped, the support rod will be reset by the elastic force of the telescopic spring, thereby resetting the buffer plate outside the rotating shaft. After the buffer plate is reset, the rotating shaft will drive the cam outside the concentric shaft to reset through the connection of the transmission belt, thereby facilitating the next knock on the bottom of the filter.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figures 1-6 The utility model provides a technical solution: a water filter device for a water mist sandblasting machine, comprising:

[0027] Example 1: Figure 1-Figure 5The technical solution shown in the figure, the utility model provides a technical solution: a water filter device of a water mist sandblasting machine, which discloses: a machine body 1, a support base 2 is fixedly installed at the lower end of the machine body 1, and a water inlet 3 is fixedly installed at the upper end of the machine body 1, and the outer side of the water inlet 3 is connected to an external water pipe 4; a filter screen 5, the filter screen 5 is fixedly installed on the inner side of the machine body 1; a buffer component 6, the buffer component 6 is arranged at the upper end of the filter screen 5; a knocking component 7, the knocking component 7 is arranged at the lower end of the filter screen 5, and the knocking component 7 is driven by the buffer component 6 for operation, wherein the buffer component 6 is adjusted in angle by the impact force of the water flow; the knocking component 7 knocks the bottom of the filter screen 5 by the angle change of the buffer component 6;

[0028] The buffer assembly 6 includes a rotating shaft 601 and a buffer plate 602. The rotating shaft 601 is rotatably connected to the inner side of the body 1, and the buffer plate 602 is fixedly installed on the outer side of the rotating shaft 601; the buffer plate 602 is arranged at the lower end of the water inlet 3; the buffer assembly 6 also includes a chute 603, a telescopic spring 604, a sliding block 605 and a support rod 606. The chute 603 is opened on the inner side of the body 1, and the telescopic spring 604 is fixedly installed on the inner side of the chute 603. The tail end of the telescopic spring 604 is fixedly connected to the sliding block 605, and the sliding block 605 is nested in the inner side of the chute 603. The outer side of the sliding block 605 is rotatably connected to the support rod 606, and the tail end of the support rod 606 is rotatably connected to the bottom of the buffer plate 602; two groups of support rods 606 are symmetrically arranged about the midpoint of the buffer plate 602;

[0029] The external water pipe 4 used in this device is an intermittent water supply device, which can prevent the water level above the filter 5 from being too high (the speed of water entering the water inlet 3 is greater than the speed of water filtering through the filter 5);

[0030] When this structure supplies water to the inside of the body 1 through the external water pipe 4, the water flow will be transported to the inside of the body 1 through the water inlet 3. During the transportation process, the water flow will impact the buffer plate 602 placed at the lower end, thereby slowing down the flow rate of the water flow through the buffer plate 602. At the same time, the buffer plate 602 will squeeze the support rod 606 under the impact of the water flow, thereby causing the support rod 606 to rotate. The sliding block 605 at the tail end of the support rod 606 squeezes the telescopic spring 604 and slides downward along the inside of the slide groove 603. After the support rod 606 rotates, the buffer plate 602 loses the support of the support rod 606 and rotates through the rotating shaft 601, thereby being placed at an angle of 45°. The water flow delayed at the upper end flows along the inclined surface of the buffer plate 602 to the filter screen 5 for filtration. Through the above structure, the impact force of the water flow is prevented from being too large to cause damage to the filter screen 5.

[0031] Example 2: Figures 1-4 、 Figure 6The technical solution shown in the figure, the utility model provides a technical solution: a water filter device for a water mist sandblasting machine, disclosed: a knocking assembly 7 includes a transmission belt 701, a concentric shaft 702 and a cam 703, the shaft portion of the concentric shaft 702 is connected to the shaft portion of the rotating shaft 601 through the transmission belt 701, and the concentric shaft 702 is rotatably connected to the inner side of the machine body 1, and a cam 703 is fixedly installed on the outer side of the concentric shaft 702, and the cam 703 is distributed in an upper and lower correspondence with the bottom of the filter screen 5; two groups of cams 703 are symmetrically arranged about the midpoint of the filter screen 5;

[0032] When the water flow drives the buffer plate 602 to rotate, the rotating shaft 601 will simultaneously drive the concentric shaft 702 to rotate through the connection of the transmission belt 701, and the rotation of the concentric shaft 702 will drive the cam 703 to rotate together. The rotation of the cam 703 will knock on the bottom of the filter screen 5, and the knocking of the filter screen 5 by the cam 703 will cause the filter screen 5 to vibrate. The generated vibration will shake out the impurities blocked inside the filter holes, preventing the filter holes from being blocked and affecting the water filtering effect. When the water supply is stopped, the support rod 606 will be reset by the elastic force of the telescopic spring 604, thereby resetting the buffer plate 602 on the outside of the rotating shaft 601. After the buffer plate 602 is reset, the rotating shaft 601 will drive the cam 703 on the outside of the concentric shaft 702 to reset through the connection of the transmission belt 701, thereby facilitating the next knocking on the bottom of the filter screen 5. Through the reciprocating water supply of the above-mentioned external water pipe 4, the protruding part of the cam 703 will reciprocally knock on the bottom of the filter screen 5, achieving the anti-clogging effect.
