[0034] The attached drawing is the best embodiment of a retractable splash guard for a filter press. The present invention will be further described in detail below with reference to the attached drawing

[0035] A retractable splash guard for a filter press includes a multi-layer splash guard 11, a slide rail support frame and an electrical control cabinet

[0036] The multi-layer splash guard 11 includes a plurality of splash guard 11 monomers with decreasing width and height arranged along the slide rail direction. The decreasing amount of the splash guard 11 is slightly less than the width of the support beam. Each splash guard 11 monomer includes left and right support surfaces and an upper support surface. Fixed beams are welded and connected in an "O" shape on the inner sides of the left and right support surfaces. The left and right surfaces of the upper support surface are welded and connected at a certain angle, and fixed beams are welded and connected in a "field" shape on the inner sides of the left and right surfaces of the upper support surface

[0037] Horizontal support beams are welded to the left and right support surfaces at both the front and rear ends of the bottom layer splash guard 11, and a vertical support beam is provided at the intersection of the left and right surfaces of the upper support surface and welded to the horizontal support beam. The rest of the splash guards 11 are provided with horizontal and vertical support beams at the front end

[0038] The left and right support surfaces of the single splash-proof cover 11 except the top layer splash-proof cover 11 are symmetrically provided with a plurality of connecting plates at the front end. The front end is along the expansion direction of the splash-proof cover 11. The width of the connecting plate is between the width of a single beam and the width of two beams, so that when the splash-proof cover 11 is expanded, the connecting plate can drive the lower layer splash-proof cover 11 to move.

[0039] The rear end of the top layer splash-proof cover 11 is provided with a hook 12 on both sides, and the hook 12 is movably connected with an iron chain. The rear end of the bottom layer splash-proof cover 11 is provided with a buckle mechanism 14, which can be movably connected with the iron chain. When maintenance is needed to move all the splash-proof covers 11, the iron chains on the hooks 12 on both sides of the top layer splash-proof cover 11 can be connected to the buckle mechanism 14 of the bottom layer splash-proof cover 11 in the collapsed state of the splash-proof cover 11, so as to drive all the splash-proof covers 11 to move.

[0040] The bottom of the splash-proof cover 11 is symmetrically provided with a plurality of groups of moving wheels on the left and right sides. The moving wheels are specifically groove wheels, and the multi-layer slide rails 21 are specifically corresponding slide rails.

[0041] The slide rail support frame includes a plurality of slide rails 21, a chain mechanism 22 and a support frame. The plurality of splash-proof covers 11 are respectively slidably connected to the independent slide rails, and the plurality of slide rails 21 of the slide rail support frame are fixedly connected in parallel by the independent slide rails. The plurality of slide rails 21 are in a decreasing relationship according to the matched splash-proof covers 11. The decreasing relationship of the plurality of slide rails 21 can effectively prevent the internal splash-proof cover 11 from being displaced when the plurality of splash-proof covers 11 are expanded, causing loose connection.

[0042] A moving groove is arranged below the plurality of slide rails 21, and an upper half of a ring chain mechanism 22 is arranged in the moving groove. One end of the chain mechanism 22 is connected with a gear, the gear is connected with a driving motor 32 and a transmission shaft 24, the other end of the transmission shaft 24 is connected with a gear and connected to the other side chain mechanism 22. A protective plate 234 is arranged outside the lower half of the ring chain mechanism 22. The protective plate 234 is specifically a hollow square tube. A plurality of support plates 233 are fixedly connected with the protective plate 234 and the horizontal total support frame 231 below the plurality of slide rails 21. A support beam is fixedly connected between the two horizontal total support frames 231, and a plurality of vertical total support frames 232 are fixedly connected with the horizontal total support frame 231.

[0043] The bottom of the top splash-proof cover 11 is fixedly connected with the driving mechanism 13 on both sides. The driving mechanism 13 specifically comprises an I-shaped bottom plate 131, a connecting arm 132, a through connecting plate 133 and a single-side bent plate chain 134. One end of the I-shaped bottom plate 131 is connected to the top splash-proof cover 11 through bolts, and the other end is fixedly connected to the connecting arm 132. The connecting arm 132 penetrates and is fixedly connected to the through connecting plate 133. The single-side bent plate chain 134 is connected to the through connecting plate 133 on the inner side. The single-side bent plate chain 134 is connected to the ring chain structure. The driving mechanism 13 moves in the front-back direction following the movement of the ring chain driven by the motor, and drives the top splash-proof cover 11 to move in the opening and closing movement.

[0044] The electrical control cabinet is internally provided with a controller which is electrically connected with the control switch, the travel switch 31 and the driving motor 32. The travel switch 31 is located at both ends of the multi-layer slide rail 21 on the slide rail support frame, and the bottom of the top splash-proof cover 11 is fixedly connected with a baffle. When the baffle opens the travel switch 31, the controller receives the signal sent by the travel switch 31, and closes the driving motor 32 so that the device no longer moves to open or close.

[0045] The specific use method of the device is as follows:

[0046] Before the device is opened, it is necessary to check whether the lock chain at the rear end of the top splash-proof cover 11 is connected with the bottom splash-proof cover 11. If the connection is made, the lock chain is removed, and if the connection is not made, the device switch can be opened. The opening button in the electrical control cabinet is pressed, and the top splash-proof cover 11 starts to move. When the baffle contacts the travel switch 31, the top splash-proof cover 11 stops moving and waits for the command. When the retracting button is pressed, the top splash-proof cover 11 moves in the opposite direction to be retracted, until the baffle contacts the travel switch 31, and the top splash-proof cover 11 stops moving.

[0047] When the device needs to be repaired, the lock chain at the rear end of the top splash-proof cover 11 is used to connect the top splash-proof cover 11 and the bottom splash-proof cover 11, and the device is moved to the middle of the track for repair operation.

[0048] The embodiments of the utility model are described in detail in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge range possessed by those skilled in the art without departing from the purpose of the utility model.
