Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of ultra-high pressure elastic pressing equipment, and in particular relates to a deep dewatering device for sludge in an ultra-high pressure elastic pressing machine. Background Technology
[0002] The high-pressure elastic press is one of the deep dewatering equipment for sludge. It combines a rigid press plate with an elastic press plate and uses hydraulic drive to deform the elastic plate and apply high pressure evenly. This avoids the "edge effect" of traditional filter presses, resulting in more uniform dewatering and stable moisture content in the sludge cake. It is suitable for scenarios with high requirements for dewatering uniformity.
[0003] Because the filter cylinder of conventional ultra-high pressure elastic pressing equipment is in a closed state, when a large amount of fibers are stuck inside and need to be cleaned, it is impossible to split it in half to clean the inside directly. Instead, one has to drill into the inside to clean it, which makes cleaning the filter cover of conventional ultra-high pressure elastic pressing equipment quite troublesome.
[0004] Therefore, we propose an ultra-high pressure elastic press sludge deep dewatering device to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to solve the problem of the troublesome cleaning of the filter cover of conventional ultra-high pressure elastic pressing equipment, and to propose a deep dewatering device for sludge in ultra-high pressure elastic pressing machines.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] The ultra-high pressure elastic press sludge deep dewatering device includes an ultra-high pressure elastic press body and a filter cover. The filter cover is divided into two parts, and a constraint sleeve is symmetrically fitted on the outside of the filter cover. A door-shaped bolt is engaged on the side of the constraint sleeve. When cleaning the filter cover, the door-shaped bolt is removed, then the constraint sleeve is removed, and then the filter cover is removed, separating the filter cover into two parts for easy cleaning of residue inside the filter cover.
[0008] Preferably, the filter cover includes a cover body, and a fastener is fixedly connected to the side end of the cover body. The fastener is fastened inside the constraint sleeve to keep the filter cover in a mated state. When high pressure is generated inside the cover body, the high pressure is further applied to the cover body, and through the cover body, it acts on the fastener, further securing the fastener to the constraint sleeve, facilitating the disassembly or assembly of the filter cover.
[0009] Preferably, the constraint sleeve includes a sleeve body, hooks are symmetrically fixedly connected to the side of the sleeve body, a drainage groove is opened on the arc surface of the sleeve body, and a buckle is fastened in the middle of the sleeve body.
[0010] Preferably, the constraint sleeve further includes a guide head, which is fixedly connected to the upper end of the hook. The guide head facilitates the guidance of the latch to engage with the hook.
[0011] Preferably, the gate-shaped bolt includes a bolt body, the lower end of which is fixedly connected to a stop block. The bolt body is mounted inside the hook, and the stop block is positioned outside the hook. By using the stop block to restrict the hook spacing between the two constraint sleeves, the hooks act on the sleeve body, causing the sleeve body to grip the filter cover tightly, thus improving the stability of the filter cover in its closed state.
[0012] Preferably, the gate bolt further includes a guide block, the upper end of which is fixedly connected to the lower end of the stop block. The guide block facilitates guiding the stop block to stay outside the hook.
[0013] In summary, the technical effects and advantages of this utility model are as follows:
[0014] 1. When cleaning the filter cover, remove the door bolt, then remove the constraint sleeve, and then remove the filter cover. Divide the filter cover into two parts to facilitate cleaning the residue inside the filter cover.
[0015] 2. The fasteners are fastened inside the constraint sleeve to keep the filter cover in a mated state. When high pressure is generated inside the cover, the high pressure is applied to the cover, which in turn applies pressure to the fasteners, making the fasteners and constraint sleeve more secure, which facilitates the disassembly or assembly of the filter cover.
[0016] 3. By using a stop block to block outside the hook, the distance between the hooks of the two constraint sleeves is limited. The hooks act on the sleeve body, making the sleeve body hug the filter cover tightly, thus improving the stability of the filter cover in the closed state. Attached Figure Description

[0022] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments.
[0023] like Figure 1 As shown, the ultra-high pressure elastic press sludge deep dewatering device includes an ultra-high pressure elastic press body 1 and a filter cover 2. The filter cover 2 is divided into two parts, and a constraint sleeve 3 is symmetrically fitted on the outside of the filter cover 2. A door bolt 4 is clamped on the side of the constraint sleeve 3.
[0024] like Figure 1 and 2 As shown, the filter cover 2 includes a cover body 21, and a fastener 22 is fixedly connected to the side end of the cover body 21. The fastener 22 is fastened inside the constraint sleeve 3 to keep the filter cover 2 in a mated state. When high pressure is generated inside the cover body 21, the high pressure is further applied to the cover body 21, and through the cover body 21, it acts on the fastener 22, so that the fastener 22 is further secured to the constraint sleeve 3.
[0025] like Figure 1 and 3 As shown, the constraint sleeve 3 includes a sleeve body 31, with hooks 32 symmetrically fixedly connected to the side of the sleeve body 31. A drainage groove 34 is formed on the arc surface of the sleeve body 31, and a fastener 22 is fastened to the middle of the sleeve body 31. The liquid squeezed out from the filter cover 2 flows downward through the drainage groove 34.
[0026] like Figure 1 and 3 As shown, the constraint sleeve 3 also includes a guide head 33, which is fixedly connected to the upper end of the hook 32. The guide head 33 is used to guide the door bolt 4 to lock onto 32.
[0027] like Figure 1 and 4 As shown, the gate-shaped bolt 4 includes a bolt body 41, with a stop block 42 fixedly connected to the lower end of the bolt body 41. The bolt body 41 is mounted inside the hook 32, and the stop block 42 is positioned outside the hook 32. By using the stop block 42 to block outside the hook 32, the distance between the hooks 32 of the two constraint sleeves 3 is limited. The hooks 32 act on the sleeve body 31, causing the sleeve body 31 to grip the filter cover 2 tightly.
[0028] like Figure 1 and 4 As shown, the door bolt 4 also includes a guide block 43, the upper end of which is fixedly connected to the lower end of the stop block 42. The guide block 43 guides the stop block 42 to stay outside the hook 32.
[0029] Working principle: When the filter cover 2 needs to be cleaned, remove the door bolt 4, then remove the constraint sleeve 3, and then remove the filter cover 2, dividing the filter cover 2 into two parts.
[0030] The above description is only a preferred embodiment of the utility model, but the protection scope of the utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed by the utility model, based on the technical solution and the utility model concept, should be included within the protection scope of the utility model.
[0031] The description briefly mentions the application direction of the utility model in relation to existing technologies known to those skilled in the art without modification, and combines them with the utility model to form a complete technology; it avoids excessive popularization of technologies known to those skilled in the art, in order to help those skilled in the art quickly understand the main content of the utility model.
