Description
Technical Field
[0001] The utility model belongs to the technical field of internal meshing gear pumps, and specifically relates to a high-viscosity internal meshing gear pump assembly for a blending device. Background Art
[0002] The internal meshing gear pump adopts the principle of internal meshing of gears. The pitch circles of the inner and outer gears are closely adjacent to one side, and the other side is separated by a "crescent plate" on the pump cover. The driving inner gear on the main shaft drives the outer gear to rotate in the same direction. At the inlet, the gears are separated from each other to form a negative pressure to suck in the liquid, and at the outlet, the gears are continuously engaged to squeeze out the liquid.
[0003] When using an internal meshing gear pump, it is necessary to install and fix the internal meshing gear pump. However, most of the existing internal meshing gear pumps are installed on the mounting plate through bolts at the four corners. This installation method requires tightening four more bolts and also requires the use of tools, which is relatively cumbersome and not convenient for subsequent disassembly and maintenance by the staff.
[0004] In view of this, the present utility model is specifically proposed. Content of the Utility Model
[0005] To solve the above technical problem that when using an internal meshing gear pump, it is necessary to install and fix the internal meshing gear pump. However, most of the existing internal meshing gear pumps are installed on the mounting plate through bolts at the four corners. This installation method requires tightening four more bolts and also requires the use of tools, which is relatively cumbersome and not convenient for subsequent disassembly and maintenance by the staff. The basic concept of the technical solution adopted by the present utility model is:
[0006] A high-viscosity internal meshing gear pump assembly for a blending device, including a gear pump;
[0007] A mounting plate arranged below the gear pump, a disassembly and assembly mechanism is arranged between the bottom end of the gear pump and the mounting plate, and a limiting mechanism is arranged on one side of the disassembly and assembly mechanism. The disassembly and assembly mechanism includes a mounting groove opened at the top end of the mounting plate:
[0008] A round hole is opened on the inner wall of the mounting groove, a fixing ring is fixedly connected to the inner wall of the round hole, a first spring is fixedly connected to the outer wall of one end of the fixing ring, a clamping convex block is fixedly connected to the end of the first spring far from the outer wall of the fixing ring, a connecting rod is fixedly connected to the outer wall of one side of the clamping convex block, a positioning rod is fixedly connected to the end of the connecting rod far from the clamping convex block, a sliding groove is opened on the outer wall of the mounting plate, a push rod is slidably arranged in the inner wall of the sliding groove, a release groove is opened on the outer wall of the push rod, a mounting block is fixedly connected to the bottom end of the gear pump, and a positioning hole is opened on the outer wall of the mounting block.
[0009] As a preferred embodiment of the present utility model, the limiting mechanism includes a connecting plate fixedly connected to the outer wall of the push rod. A limiting hole is provided at one end of the connecting plate away from the push rod. A groove is provided on the outer wall of the mounting plate. A sliding hole is provided on the inner wall of the groove. A second spring is fixedly connected to the inner wall of the sliding hole. One end of the second spring away from the inner wall of the sliding hole is fixedly connected to a limiting rod. A dial plate is fixedly connected to the outer wall of the limiting rod.
[0010] As a preferred embodiment of the present utility model, the number of the mounting grooves and the mounting blocks is four respectively. The mounting grooves and the mounting blocks are arranged in pairs and are symmetrically distributed on the mounting plate and the gear pump in a left-right symmetrical structure.
[0011] As a preferred embodiment of the present utility model, the inner wall of the mounting groove is fitted with the outer wall of the mounting block, and the inner wall of the positioning hole is fitted with the outer wall of the positioning rod.
[0012] As a preferred embodiment of the present utility model, the inner wall of the sliding groove provided on the outer wall of the mounting plate is fitted with the outer wall of the push rod.
[0013] As a preferred embodiment of the present utility model, a communication groove is provided on the inner wall of the sliding hole provided on the inner wall of the groove on the mounting plate. The outer wall of the dial plate is slidably arranged on the inner wall of the communication groove.
[0014] As a preferred embodiment of the present utility model, the inner wall of the limiting hole is fitted with the outer wall of the limiting rod.
[0015] The present utility model has the following beneficial effects compared with the prior art:
[0016] In the present utility model, first, the push rod is pulled outwards. At this time, the push rod will drive the release groove on the outer wall to move until the release groove is moved to the position of the engaging convex block. At this time, the engaging convex block will lose the extrusion limit of the push rod, so that the first spring will rebound and reset, pushing the engaging convex block to move to one side, and then engaging into the release groove. In this way, during the movement of the engaging convex block, the positioning rod will be driven to move inwards, so that the positioning rod retracts into the round hole provided on the inner wall of the mounting groove. After that, the mounting block can be aligned and inserted into the inside of the mounting groove. After the insertion and engagement are completed, the push rod can be pushed forward. At this time, the inner wall of the release groove will exert an extrusion effect on the engaging convex block. The squeezed engaging convex block will drive the positioning rod to move back to its original position, and at the same time, the first spring will be stretched during the movement. At this time, the outer wall of the positioning rod will extend out of the round hole and then insert into the inner wall of the positioning hole, so that the mounting block can be limited, thus completing the installation of the gear pump. This method does not require repeated screwing of bolts for installation, and at the same time, no tools are needed to complete the installation, which is convenient for the staff to disassemble, install and repair.
[0017] In this utility model, after pushing the push rod to the inner wall of the groove opened on the outer wall of the mounting plate, the dial plate is synchronously toggled to move to the right. At this time, the dial plate will drive the limiting rod to move to the right. At the same time, during the movement of the limiting rod, the second spring will be compressed. Subsequently, the push rod will drive the connecting plate to insert into the inner wall of the slot opened on the outer wall of the mounting plate. After the insertion is completed, the dial plate can be released. Through the rebounding action of the second spring, the limiting rod can be pushed to move back to its original position, and then inserted into the limiting hole to limit the push rod and prevent the push rod from moving, so as to avoid the loosening of the installation of the gear pump.

Specific Embodiment
[0025] To make the purposes, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model.
[0026] As Figures 1 to 4As shown in the figure, a high-viscosity internal gear pump assembly for a blending device includes a gear pump 1, a mounting plate 2 disposed below the gear pump 1, a disassembly and assembly mechanism 31 is provided between the bottom end of the gear pump 1 and the mounting plate 2, and a limiting mechanism 32 is disposed on one side of the disassembly and assembly mechanism 31. The disassembly and assembly mechanism 31 includes a mounting groove 311 opened at the top end of the mounting plate 2. A circular hole is opened on the inner wall of the mounting groove 311, and a fixing ring 312 is fixedly connected to the inner wall of the circular hole. One end of the outer wall of the fixing ring 312 is fixedly connected to a first spring 313. The end of the first spring 313 away from the outer wall of the fixing ring 312 is fixedly connected to a clamping convex block 314. One side of the outer wall of the clamping convex block 314 is fixedly connected to a connecting rod 315. The end of the connecting rod 315 away from the clamping convex block 314 is fixedly connected to a positioning rod 316. A chute is opened on the outer wall of the mounting plate 2, and a push rod 317 is slidably disposed on the inner wall of the chute. A release groove 318 is opened on the outer wall of the push rod 317. The bottom end of the gear pump 1 is fixedly connected to a mounting block 319, and a positioning hole 3110 is opened on the outer wall of the mounting block 319.
[0027] Furthermore, the number of the mounting grooves 311 and the mounting blocks 319 is four respectively. The mounting grooves 311 and the mounting blocks 319 are opposite to each other in pairs and are symmetrically distributed on the mounting plate 2 and the gear pump 1 in a left-right symmetrical structure, so as to perform a clamping and limiting function on the left, right, upper and lower sides of the gear pump 1 synchronously, thereby improving the mounting stability of the gear pump 1.
[0028] Furthermore, the inner wall of the mounting groove 311 is fitted with the outer wall of the mounting block 319, and the inner wall of the positioning hole 3110 is fitted with the outer wall of the positioning rod 316, so as to ensure the stability of the gear pump 1 mounted on the mounting plate 2.
[0029] Even further, the inner wall of the chute opened on the outer wall of the mounting plate 2 is fitted with the outer wall of the push rod 317, so as to ensure the tight fit between the outer wall of the push rod 317 and the inner wall of the chute, thereby ensuring the stability of the push rod 317 during movement and fixing.
[0030] The limiting mechanism 32 includes a connecting plate 321 fixedly connected to the outer wall of the push rod 317. A limiting hole 322 is opened at the end of the connecting plate 321 away from the push rod 317. A groove is opened on the outer wall of the mounting plate 2. A sliding hole is opened on the inner wall of the groove. A second spring 323 is fixedly connected to the inner wall of the sliding hole. The end of the second spring 323 away from the inner wall of the sliding hole is fixedly connected to a limiting rod 324. A dial plate 325 is fixedly connected to the outer wall of the limiting rod 324.
[0031] Furthermore, a communication groove is opened on the inner wall of the sliding hole opened on the inner wall of the groove on the mounting plate 2. The outer wall of the dial plate 325 is slidably disposed on the inner wall of the communication groove, so as to provide a moving space for the dial plate 325, thereby facilitating the positioning and de-positioning operations of the push rod 317.
[0032] Further, the inner wall of the limiting hole 322 is fitted with the outer wall of the limiting rod 324, so as to ensure the stability of the limiting rod 324 clamped on the inner wall of the limiting hole 322.
[0033] The implementation principle of a high-viscosity internal gear pump assembly for a blending device in this embodiment is as follows: During installation, first pull the push rod 317 outwards. At this time, the push rod 317 will drive the release groove 318 on the outer wall to move until the release groove 318 moves to the position of the engaging convex block 314. At this time, the engaging convex block 314 will lose the extrusion limit of the push rod 317. Then the first spring 313 will rebound and reset, pushing the engaging convex block 314 to move to one side and then engaging into the release groove 318. In the process of the engaging convex block 314 moving, it will drive the positioning rod 316 to move inwards, so that the positioning rod 316 retracts into the round hole opened on the inner wall of the installation groove 311. After that, the installation block 319 can be aligned and inserted into the inside of the installation groove 311. After the insertion and engagement are completed, the push rod 317 can be pushed forward. At this time, the inner wall of the release groove 318 will exert an extrusion effect on the engaging convex block 314. The squeezed engaging convex block 314 will drive the positioning rod 316 to move back to its original position, and at the same time, the first spring 313 will be stretched during the movement. At this time, the outer wall of the positioning rod 316 will extend out of the round hole and then insert into the inner wall of the positioning hole 3110, so as to limit the installation block 319, thus completing the installation of the gear pump 1. This method does not require repeatedly screwing bolts for installation, and at the same time, no tools are needed to complete the installation, which is convenient for the staff to disassemble, install and overhaul.
[0034] After the push rod 317 is pushed into the inner wall of the groove opened on the outer wall of the mounting plate 2, the dial plate 325 is synchronously dialed to move to the right. At this time, the dial plate 325 will drive the limiting rod 324 to move to the right. At the same time, during the movement of the limiting rod 324, it will exert an extrusion effect on the second spring 323. Then the push rod 317 will drive the connecting plate 321 to insert into the inner wall of the slot opened on the outer wall of the mounting plate 2. After the insertion is completed, the dial plate 325 can be released. Through the rebounding action of the second spring 323, the limiting rod 324 can be pushed to move back to its original position and then inserted into the limiting hole 322 to limit the push rod 317 and prevent the push rod 317 from moving, so that the installation of the gear pump 1 becomes loose.
